+
+```python
+class BaseField(FieldInfo)
+```
+
+BaseField serves as a parent class for all basic Fields in ormar.
+It keeps all common parameters available for all fields as well as
+set of useful functions.
+
+All values are kept as class variables, ormar Fields are never instantiated.
+Subclasses pydantic.FieldInfo to keep the fields related
+to pydantic field types like ConstrainedStr

+
+Iterates over declared on Model model fields and extracts fields that
+should be treated as database fields.
+
+If the model is empty it sets mandatory id field as primary key
+(used in through models in m2m relations).
+
+Triggers a validation of relation_names in relation fields. If multiple fields
+are leading to the same related model only one can have empty related_name param.
+Also related_names have to be unique.
+
+Trigger validation of primary_key - only one and required pk can be set,

+
+Extracts fields from base classes if they have valid oramr fields.
+
+If model was already parsed -> fields definitions need to be removed from class

+
+If the class is parsed first time annotations and field definition is parsed
+from the class.__dict__.
+
+If the class is a ormar.Model it is skipped.

+
+Model method to convert raw sql row from database into ormar.Model instance.
+Traverses nested models if they were specified in select_related for query.
+
+Called recurrently and returns model instance if it's present in the row.
+Note that it's processing one row at a time, so if there are duplicates of
+parent row that needs to be joined/combined
+(like parent row in sql join with 2+ child rows)
+instances populated in this method are later combined in the QuerySet.
+Other method working directly on raw database results is in prefetch_query,

+
+**Arguments**:

+```
+
+Traverses structure of related models and populates the nested models
+from the database row.
+Related models can be a list if only directly related models are to be
+populated, converted to dict if related models also have their own related
+models to be populated.

+
+Extracts own fields from raw sql result, using a given prefix.
+Prefix changes depending on the table's position in a join.
+
+If the table is a main table, there is no prefix.
+All joined tables have prefixes to allow duplicate column names,

+#### save
+
+```python
+ | async save() -> T
+```
+
+Performs a save of given Model instance.
+If primary key is already saved, db backend will throw integrity error.
+
+Related models are saved by pk number, reverse relation and many to many fields
+are not saved - use corresponding relations methods.
+
+If there are fields with server_default set and those fields
+are not already filled save will trigger also a second query
+to refreshed the fields populated server side.
+
+Does not recognize if model was previously saved.
+If you want to perform update or insert depending on the pk
+fields presence use upsert.

+```
+
+Triggers a upsert method on all related models
+if the instances are not already saved.
+By default saves only the directly related ones.
+
+If follow=True is set it saves also related models of related models.
+
+To not get stuck in an infinite loop as related models also keep a relation
+to parent model visited models set is kept.
+
+That way already visited models that are nested are saved, but the save do not
+follow them inside. So Model A -> Model B -> Model A -> Model C will save second
+Model A but will never follow into Model C.
+Nested relations of those kind need to be persisted manually.
+
+**Arguments**:
+
+- `follow (bool)`: flag to trigger deep save -

+
+**Arguments**:

+
+Sends pre_update and post_update signals.
+
+Sets model save status to True.
+
+**Raises**:
+
+- `ModelPersistenceError`: If the pk column is not set will throw ModelPersistenceError
+
+**Arguments**:
+
+- `kwargs (Any)`: list of fields to update as field=value pairs

+<a name="models.model.Model.delete"></a>
+#### delete
+
+```python
+ | async delete() -> int
+```
+
+Removes the Model instance from the database.
+
+Sends pre_delete and post_delete signals.
+
+Sets model save status to False.
+
+Note it does not delete the Model itself (python object).
+So you can delete and later save (since pk is deleted no conflict will arise)
+or update and the Model will be saved in database again.
+
+**Returns**:
+
+`(int)`: number of deleted rows (for some backends)
+
+<a name="models.model.Model.load"></a>
+#### load
+
+```python

+
+Allow to refresh existing Models fields from database.
+Be careful as the related models can be overwritten by pk_only models in load.
+Does NOT refresh the related models fields if they were loaded before.
+
+**Raises**:
+
+- `NoMatch`: If given pk is not found in database the NoMatch exception is raised.
+
+**Returns**:

+```
+
+Main base class of ormar Model.
+Inherits from pydantic BaseModel and has all mixins combined in ModelTableProxy.
+Constructed with ModelMetaclass which in turn also inherits pydantic metaclass.
+
+Abstracts away all internals and helper functions, so final Model class has only

+#### \_\_init\_\_
+
+```python
+ | __init__(*args: Any, **kwargs: Any) -> None
+```
+
+Initializer that creates a new ormar Model that is also pydantic Model at the
+same time.
+
+Passed keyword arguments can be only field names and their corresponding values
+as those will be passed to pydantic validation that will complain if extra
+params are passed.
+
+If relations are defined each relation is expanded and children models are also
+initialized and validated. Relation from both sides is registered so you can
+access related models from both sides.
+
+Json fields are automatically loaded/dumped if needed.
+
+Models marked as abstract=True in internal Meta class cannot be initialized.
+
+Accepts also special __pk_only__ flag that indicates that Model is constructed
+only with primary key value (so no other fields, it's a child model on other
+Model), that causes skipping the validation, that's the only case when the
+validation can be skipped.
+
+Accepts also special __excluded__ parameter that contains a set of fields that
+should be explicitly set to None, as otherwise pydantic will try to populate
+them with their default values if default is set.
+
+**Raises**:
+

+
+Overwrites setattr in object to allow for special behaviour of certain params.
+
+Parameter "pk" is translated into actual primary key field name.
+
+Relations are expanded (child model constructed if needed) and registered on
+both ends of the relation. The related models are handled by RelationshipManager
+exposed at _orm param.
+
+Json fields converted if needed.
+
+Setting pk, foreign key value or any other field value sets Model save status
+to False. Setting a reverse relation or many to many relation does not as it
+does not modify the state of the model (but related model or through model).
+
+To short circuit all checks and expansions the set of attribute names present
+on each model is gathered into _quick_access_fields that is looked first and

+```
+
+Because we need to overwrite getting the attribute by ormar instead of pydantic
+as well as returning related models and not the value stored on the model the
+__getattribute__ needs to be used not __getattr__.
+
+It's used to access all attributes so it can be a big overhead that's why a
+number of short circuits is used.
+
+To short circuit all checks and expansions the set of attribute names present
+on each model is gathered into _quick_access_fields that is looked first and
+if field is in this set the object setattr is called directly.
+
+To avoid recursion object's getattribute is used to actually get the attribute
+value from the model after the checks.
+
+Even the function calls are constructed with objects functions.
+
+Parameter "pk" is translated into actual primary key field name.
+
+Relations are returned so the actual related model is returned and not current
+model's field. The related models are handled by RelationshipManager exposed

+
+Allows you to filter by any `Model` attribute/field
+as well as to fetch instances, with a filter across an FK relationship.
+
+You can use special filter suffix to change the filter operands:
+
+*  exact - like `album__name__exact='Malibu'` (exact match)
+*  iexact - like `album__name__iexact='malibu'` (exact match case insensitive)
+*  contains - like `album__name__contains='Mal'` (sql like)
+*  icontains - like `album__name__icontains='mal'` (sql like case insensitive)
+*  in - like `album__name__in=['Malibu', 'Barclay']` (sql in)
+*  gt - like `position__gt=3` (sql >)
+*  gte - like `position__gte=3` (sql >=)
+*  lt - like `position__lt=3` (sql <)
+*  lte - like `position__lte=3` (sql <=)
+*  startswith - like `album__name__startswith='Mal'` (exact start match)
+*  istartswith - like `album__name__istartswith='mal'` (case insensitive)
+*  endswith - like `album__name__endswith='ibu'` (exact end match)
+*  iendswith - like `album__name__iendswith='IBU'` (case insensitive)

+
+<a name="queryset.queryset.QuerySet.exclude"></a>
+#### exclude
+
+```python
+ | exclude(**kwargs: Any) -> "QuerySet"
+```
+
+Works exactly the same as filter and all modifiers (suffixes) are the same,
+but returns a *not* condition.
+
+So if you use `filter(name='John')` which is `where name = 'John'` in SQL,
+the `exclude(name='John')` equals to `where name <> 'John'`
+
+Note that all conditions are joined so if you pass multiple values it
+becomes a union of conditions.
+
+`exclude(name='John', age>=35)` will become
+`where not (name='John' and age>=35)`
+
+**Arguments**:
+
+- `kwargs (Any)`: fields names and proper value types
+
+**Returns**:
+
+`(QuerySet)`: filtered QuerySet
+
+<a name="queryset.queryset.QuerySet.select_related"></a>
+#### select\_related
+
+```python
+ | select_related(related: Union[List, str]) -> "QuerySet"
+```
+
+Allows to prefetch related models during the same query.
+
+**With `select_related` always only one query is run against the database**,
+meaning that one (sometimes complicated) join is generated and later nested
+models are processed in python.
+
+To fetch related model use `ForeignKey` names.
+
+To chain related `Models` relation use double underscores between names.
+
+**Arguments**:
+
+- `related (Union[List, str])`: list of relation field names, can be linked by '__' to nest
+
+**Returns**:
+
+`(QuerySet)`: QuerySet
+
+<a name="queryset.queryset.QuerySet.prefetch_related"></a>
+#### prefetch\_related
+
+```python
+ | prefetch_related(related: Union[List, str]) -> "QuerySet"
+```
+
+Allows to prefetch related models during query - but opposite to
+`select_related` each subsequent model is fetched in a separate database query.
+
+**With `prefetch_related` always one query per Model is run against the
+database**, meaning that you will have multiple queries executed one
+after another.
+
+To fetch related model use `ForeignKey` names.
+
+To chain related `Models` relation use double underscores between names.
+
+**Arguments**:
+
+- `related (Union[List, str])`: list of relation field names, can be linked by '__' to nest
+
+**Returns**:
+
+`(QuerySet)`: QuerySet
+
+<a name="queryset.queryset.QuerySet.fields"></a>
+#### fields
+
+```python
+ | fields(columns: Union[List, str, Set, Dict]) -> "QuerySet"
+```
+
+With `fields()` you can select subset of model columns to limit the data load.
+
+Note that `fields()` and `exclude_fields()` works both for main models
+(on normal queries like `get`, `all` etc.)
+as well as `select_related` and `prefetch_related`
+models (with nested notation).
+
+You can select specified fields by passing a `str, List[str], Set[str] or
+dict` with nested definition.
+
+To include related models use notation
+`{related_name}__{column}[__{optional_next} etc.]`.
+
+`fields()` can be called several times, building up the columns to select.
+
+If you include related models into `select_related()` call but you won't specify
+columns for those models in fields - implies a list of all fields for
+those nested models.
+
+Mandatory fields cannot be excluded as it will raise `ValidationError`,
+to exclude a field it has to be nullable.
+
+Pk column cannot be excluded - it's always auto added even if
+not explicitly included.
+
+You can also pass fields to include as dictionary or set.
+
+To mark a field as included in a dictionary use it's name as key
+and ellipsis as value.
+
+To traverse nested models use nested dictionaries.
+
+To include fields at last level instead of nested dictionary a set can be used.
+
+To include whole nested model specify model related field name and ellipsis.
+
+**Arguments**:
+
+- `columns (Union[List, str, Set, Dict])`: columns to include
+
+**Returns**:
+
+`(QuerySet)`: QuerySet
+
+<a name="queryset.queryset.QuerySet.exclude_fields"></a>
+#### exclude\_fields
+
+```python
+ | exclude_fields(columns: Union[List, str, Set, Dict]) -> "QuerySet"
+```
+
+With `exclude_fields()` you can select subset of model columns that will
+be excluded to limit the data load.
+
+It's the opposite of `fields()` method so check documentation above
+to see what options are available.
+
+Especially check above how you can pass also nested dictionaries
+and sets as a mask to exclude fields from whole hierarchy.
+
+Note that `fields()` and `exclude_fields()` works both for main models
+(on normal queries like `get`, `all` etc.)
+as well as `select_related` and `prefetch_related` models
+(with nested notation).
+
+Mandatory fields cannot be excluded as it will raise `ValidationError`,
+to exclude a field it has to be nullable.
+
+Pk column cannot be excluded - it's always auto added even
+if explicitly excluded.
+
+**Arguments**:
+
+- `columns (Union[List, str, Set, Dict])`: columns to exclude
+
+**Returns**:
+
+`(QuerySet)`: QuerySet
+
+<a name="queryset.queryset.QuerySet.order_by"></a>
+#### order\_by
+
+```python
+ | order_by(columns: Union[List, str]) -> "QuerySet"
+```
+
+With `order_by()` you can order the results from database based on your
+choice of fields.
+
+You can provide a string with field name or list of strings with fields names.
+
+Ordering in sql will be applied in order of names you provide in order_by.
+
+By default if you do not provide ordering `ormar` explicitly orders by
+all primary keys
+
+If you are sorting by nested models that causes that the result rows are
+unsorted by the main model `ormar` will combine those children rows into
+one main model.
+
+The main model will never duplicate in the result
+
+To order by main model field just provide a field name
+
+To sort on nested models separate field names with dunder '__'.
+
+You can sort this way across all relation types -> `ForeignKey`,
+reverse virtual FK and `ManyToMany` fields.
+
+To sort in descending order provide a hyphen in front of the field name

+#### filter
+
+```python
+ | filter(**kwargs: Any) -> "QuerysetProxy"
+```
+
+Allows you to filter by any `Model` attribute/field
+as well as to fetch instances, with a filter across an FK relationship.
+
+You can use special filter suffix to change the filter operands:
+
+*  exact - like `album__name__exact='Malibu'` (exact match)
+*  iexact - like `album__name__iexact='malibu'` (exact match case insensitive)
+*  contains - like `album__name__contains='Mal'` (sql like)
+*  icontains - like `album__name__icontains='mal'` (sql like case insensitive)
+*  in - like `album__name__in=['Malibu', 'Barclay']` (sql in)
+*  gt - like `position__gt=3` (sql >)
+*  gte - like `position__gte=3` (sql >=)
+*  lt - like `position__lt=3` (sql <)
+*  lte - like `position__lte=3` (sql <=)
+*  startswith - like `album__name__startswith='Mal'` (exact start match)
+*  istartswith - like `album__name__istartswith='mal'` (case insensitive)

+#### exclude
+
+```python
+ | exclude(**kwargs: Any) -> "QuerysetProxy"
+```
+
+Works exactly the same as filter and all modifiers (suffixes) are the same,
+but returns a *not* condition.
+
+So if you use `filter(name='John')` which is `where name = 'John'` in SQL,
+the `exclude(name='John')` equals to `where name <> 'John'`
+
+Note that all conditions are joined so if you pass multiple values it
+becomes a union of conditions.
+
+`exclude(name='John', age>=35)` will become
+`where not (name='John' and age>=35)`
+
+Actual call delegated to QuerySet.
+
+**Arguments**:
+
+- `kwargs (Any)`: fields names and proper value types
+
+**Returns**:
+
+`(QuerysetProxy)`: filtered QuerysetProxy
+
+<a name="relations.querysetproxy.QuerysetProxy.select_related"></a>
+#### select\_related
+
+```python
+ | select_related(related: Union[List, str]) -> "QuerysetProxy"
+```
+
+Allows to prefetch related models during the same query.
+
+**With `select_related` always only one query is run against the database**,
+meaning that one (sometimes complicated) join is generated and later nested
+models are processed in python.
+
+To fetch related model use `ForeignKey` names.
+
+To chain related `Models` relation use double underscores between names.
+
+Actual call delegated to QuerySet.
+
+**Arguments**:
+
+- `related (Union[List, str])`: list of relation field names, can be linked by '__' to nest
+
+**Returns**:
+
+`(QuerysetProxy)`: QuerysetProxy
+
+<a name="relations.querysetproxy.QuerysetProxy.prefetch_related"></a>
+#### prefetch\_related
+
+```python
+ | prefetch_related(related: Union[List, str]) -> "QuerysetProxy"
+```
+
+Allows to prefetch related models during query - but opposite to
+`select_related` each subsequent model is fetched in a separate database query.
+
+**With `prefetch_related` always one query per Model is run against the
+database**, meaning that you will have multiple queries executed one
+after another.
+
+To fetch related model use `ForeignKey` names.
+
+To chain related `Models` relation use double underscores between names.
+
+Actual call delegated to QuerySet.
+
+**Arguments**:
+
+- `related (Union[List, str])`: list of relation field names, can be linked by '__' to nest
+
+**Returns**:
+
+`(QuerysetProxy)`: QuerysetProxy
+
+<a name="relations.querysetproxy.QuerysetProxy.limit"></a>
+#### limit
+
+```python
+ | limit(limit_count: int) -> "QuerysetProxy"

+
+Actual call delegated to QuerySet.
+
+**Arguments**:
+
+- `limit_count (int)`: number of models to limit
+
+**Returns**:
+
+`(QuerysetProxy)`: QuerysetProxy
+
+<a name="relations.querysetproxy.QuerysetProxy.offset"></a>

+
+**Arguments**:
+
+- `offset (int)`: numbers of models to offset
+
+**Returns**:
+
+`(QuerysetProxy)`: QuerysetProxy
+
+<a name="relations.querysetproxy.QuerysetProxy.fields"></a>
+#### fields
+
+```python
+ | fields(columns: Union[List, str, Set, Dict]) -> "QuerysetProxy"
+```
+
+With `fields()` you can select subset of model columns to limit the data load.
+
+Note that `fields()` and `exclude_fields()` works both for main models
+(on normal queries like `get`, `all` etc.)
+as well as `select_related` and `prefetch_related`
+models (with nested notation).
+
+You can select specified fields by passing a `str, List[str], Set[str] or
+dict` with nested definition.
+
+To include related models use notation
+`{related_name}__{column}[__{optional_next} etc.]`.
+
+`fields()` can be called several times, building up the columns to select.
+
+If you include related models into `select_related()` call but you won't specify
+columns for those models in fields - implies a list of all fields for
+those nested models.
+
+Mandatory fields cannot be excluded as it will raise `ValidationError`,
+to exclude a field it has to be nullable.
+
+Pk column cannot be excluded - it's always auto added even if
+not explicitly included.
+
+You can also pass fields to include as dictionary or set.
+
+To mark a field as included in a dictionary use it's name as key
+and ellipsis as value.
+
+To traverse nested models use nested dictionaries.
+
+To include fields at last level instead of nested dictionary a set can be used.
+
+To include whole nested model specify model related field name and ellipsis.
+
+Actual call delegated to QuerySet.
+
+**Arguments**:
+
+- `columns (Union[List, str, Set, Dict])`: columns to include
+
+**Returns**:
+
+`(QuerysetProxy)`: QuerysetProxy
+
+<a name="relations.querysetproxy.QuerysetProxy.exclude_fields"></a>
+#### exclude\_fields
+
+```python
+ | exclude_fields(columns: Union[List, str, Set, Dict]) -> "QuerysetProxy"
+```
+
+With `exclude_fields()` you can select subset of model columns that will
+be excluded to limit the data load.
+
+It's the opposite of `fields()` method so check documentation above
+to see what options are available.
+
+Especially check above how you can pass also nested dictionaries
+and sets as a mask to exclude fields from whole hierarchy.
+
+Note that `fields()` and `exclude_fields()` works both for main models
+(on normal queries like `get`, `all` etc.)
+as well as `select_related` and `prefetch_related` models
+(with nested notation).
+
+Mandatory fields cannot be excluded as it will raise `ValidationError`,
+to exclude a field it has to be nullable.
+
+Pk column cannot be excluded - it's always auto added even
+if explicitly excluded.
+
+Actual call delegated to QuerySet.
+
+**Arguments**:
+
+- `columns (Union[List, str, Set, Dict])`: columns to exclude
+
+**Returns**:
+
+`(QuerysetProxy)`: QuerysetProxy
+
+<a name="relations.querysetproxy.QuerysetProxy.order_by"></a>
+#### order\_by
+
+```python
+ | order_by(columns: Union[List, str]) -> "QuerysetProxy"
+```
+
+With `order_by()` you can order the results from database based on your
+choice of fields.
+
+You can provide a string with field name or list of strings with fields names.
+
+Ordering in sql will be applied in order of names you provide in order_by.
+
+By default if you do not provide ordering `ormar` explicitly orders by
+all primary keys
+
+If you are sorting by nested models that causes that the result rows are
+unsorted by the main model `ormar` will combine those children rows into
+one main model.
+
+The main model will never duplicate in the result
+
+To order by main model field just provide a field name
+
+To sort on nested models separate field names with dunder '__'.
+
+You can sort this way across all relation types -> `ForeignKey`,
+reverse virtual FK and `ManyToMany` fields.
+
+To sort in descending order provide a hyphen in front of the field name
+
+Actual call delegated to QuerySet.
+
+**Arguments**:
+
+- `columns (Union[List, str])`: columns by which models should be sorted
+
+**Returns**:
+
+`(QuerysetProxy)`: QuerysetProxy

+The `ormar` package is an async mini ORM for Python, with support for **Postgres,
+MySQL**, and **SQLite**.
+
+The main benefit of using `ormar` are:
+
+*  getting an **async ORM that can be used with async frameworks**
+(fastapi, starlette etc.)
+*  getting just **one model to maintain** - you don't have to maintain pydantic
+and other orm model (sqlalchemy, peewee, gino etc.)
+
+The goal was to create a simple ORM that can be **used directly
+(as request and response models)
+with `fastapi`** that bases it's data validation on pydantic.
+
+Ormar - apart form obvious ORM in name - get it's name from ormar in swedish which means
+snakes, and ormar(e) in italian which means cabinet.
+
+And what's a better name for python ORM than snakes cabinet :)
