Method	__init__	Undocumented
Method	formfield	Return a django.forms.Field instance for this field.
Method	get​_prep​_value	Perform preliminary non-db specific value checks and conversions.
Method	model.setter	Undocumented
Method	set​_attributes​_from​_name	Undocumented
Method	to​_python	Convert the input value into the expected Python data type, raising django.core.exceptions.ValidationError if the data can't be converted. Return the converted value. Subclasses should override this.
Method	value​_to​_string	Return a string value of this field from the passed obj. This is used by the serialization framework.
Class Variable	empty​_strings​_allowed	Undocumented
Instance Variable	base​_field	Undocumented

Inherited from Field (via RangeField):

Method	__copy__	Undocumented
Method	__deepcopy__	Undocumented
Method	__eq__	Undocumented
Method	__hash__	Undocumented
Method	__lt__	Undocumented
Method	__reduce__	Pickling should return the model._meta.fields instance of the field, not a new copy of that field. So, use the app registry to load the model and then the field back.
Method	__repr__	Display the module, class, and name of the field.
Method	__str__	Return "app_label.model_label.field_name" for fields attached to models.
Method	​_check​_backend​_specific​_checks	Undocumented
Method	​_check​_choices	Undocumented
Method	​_check​_db​_index	Undocumented
Method	​_check​_deprecation​_details	Undocumented
Method	​_check​_field​_name	Check if field name is valid, i.e. 1) does not end with an underscore, 2) does not contain "__" and 3) is not "pk".
Method	​_check​_null​_allowed​_for​_primary​_keys	Undocumented
Method	​_check​_validators	Undocumented
Method	​_description	Undocumented
Method	​_get​_flatchoices	Flattened version of choices tuple.
Method	cast​_db​_type	Return the data type to use in the Cast() function.
Method	check	Undocumented
Method	clean	Convert the value's type and run validation. Validation errors from to_python() and validate() are propagated. Return the correct value if no error is raised.
Method	clone	Uses deconstruct() to clone a new copy of this Field. Will not preserve any class attachments/attribute names.
Method	contribute​_to​_class	Register the field with the model class it belongs to.
Method	db​_check	Return the database column check constraint for this field, for the provided connection. Works the same way as db_type() for the case that get_internal_type() does not map to a preexisting model field.
Method	db​_parameters	Extension of db_type(), providing a range of different return values (type, checks). This will look at db_type(), allowing custom model fields to override it.
Method	db​_type​_parameters	Undocumented
Method	db​_type​_suffix	Undocumented
Method	deconstruct	Return enough information to recreate the field as a 4-tuple:
Method	get​_attname	Undocumented
Method	get​_attname​_column	Undocumented
Method	get​_choices	Return choices with a default blank choices included, for use as <select> choices for this field.
Method	get​_col	Undocumented
Method	get​_db​_converters	Undocumented
Method	get​_db​_prep​_save	Return field's value prepared for saving into a database.
Method	get​_db​_prep​_value	Return field's value prepared for interacting with the database backend.
Method	get​_default	Return the default value for this field.
Method	get​_filter​_kwargs​_for​_object	Return a dict that when passed as kwargs to self.model.filter(), would yield all instances having the same value for this field as obj has.
Method	get​_internal​_type	Undocumented
Method	get​_pk​_value​_on​_save	No summary
Method	has​_default	Return a boolean of whether this field has a default value.
Method	pre​_save	Return field's value just before saving.
Method	rel​_db​_type	Return the data type that a related field pointing to this field should use. For example, this method is called by ForeignKey and OneToOneField to determine its data type.
Method	run​_validators	Undocumented
Method	save​_form​_data	Undocumented
Method	select​_format	Custom format for select clauses. For example, GIS columns need to be selected as AsText(table.col) on MySQL as the table.col data can't be used by Django.
Method	validate	Validate value and raise ValidationError if necessary. Subclasses should override this to provide validation logic.
Method	value​_from​_object	Return the value of this field in the given model instance.
