Methods

• ▷ def __eq__(self, other)

  source link
• ▷ def __getstate__(self)

  Hook to allow choosing the attributes to pickle.

• ▷ def __hash__(self)

  source link
• ▷ def __init__(self, *args, **kwargs)

  source link
• ▷ def __reduce__(self)

  source link

  Overrides

  This method is overriden in:

  • django.contrib.admin.models.LogEntry
• ▷ def __setstate__(self, state)

  source link
• ▶ def __str__(self)

  source link

  Overrides

  This method is overriden in:

  • django.contrib.sessions.base_session.AbstractBaseSession
  • django.contrib.gis.db.backends.postgis.models.PostGISGeometryColumns
  • django.contrib.gis.db.backends.spatialite.models.SpatialiteGeometryColumns
  • django.contrib.admin.models.LogEntry

  • django.contrib.auth.models.Group
  • django.contrib.auth.base_user.AbstractBaseUser
  • django.contrib.redirects.models.Redirect
  • django.contrib.sites.models.Site
  • django.contrib.flatpages.models.FlatPage
  • django.contrib.contenttypes.models.ContentType
• ▶ def clean(self)

  Hook for doing any extra model-wide validation after clean() has been

  source link

  called on every field by self.clean_fields. Any ValidationError raised
  by this method will not be associated with a particular field; it will
  have a special-case association with the field defined by NON_FIELD_ERRORS.

  Overrides

  This method is overriden in:

  • django.contrib.auth.base_user.AbstractBaseUser
• ▷ def clean_fields(self, exclude=None)

  Clean all fields and raise a ValidationError containing a dict of all validation errors if any occur.

  source link
• ▷ def date_error_message(self, lookup_type, field_name, unique_for)

  source link
• ▷ def delete(self, using=None, keep_parents=False)

  source link
• ▷ def full_clean(self, exclude=None, validate_unique=True)

  Call clean_fields(), clean(), and validate_unique() on the model. Raise a ValidationError for any errors that occur.

  source link
• ▷ def get_deferred_fields(self)

  Return a set containing names of deferred fields for this instance.

  source link
• ▷ def prepare_database_save(self, field)

  source link
• ▶ def refresh_from_db(self, using=None, fields=None)

  Reload field values from the database.

  source link

  By default, the reloading happens from the database this instance was
  loaded from, or by the read router if this instance wasn't loaded from
  any database. The using parameter will override the default.
  
  Fields can be used to specify which fields to reload. The fields
  should be an iterable of field attnames. If fields is None, then
  all non-deferred fields are reloaded.
  
  When accessing deferred fields of an instance, the deferred loading
  of the field will call this method.

• ▶ def save(self, force_insert=False, force_update=False, using=None, update_fields=None)

  Save the current instance. Override this in a subclass if you want to control the saving process.

  source link

  The 'force_insert' and 'force_update' parameters can be used to insist
  that the "save" must be an SQL insert or update (or equivalent for
  non-SQL backends), respectively. Normally, they should not be set.

  Overrides

  This method is overriden in:

  • django.contrib.auth.base_user.AbstractBaseUser
• ▶ def save_base(self, raw=False, force_insert=False, force_update=False, using=None, ...)

  Handle the parts of saving which should be done only once per save, yet need to be done in raw saves, too. This includes some sanity checks and signal sending.

  def save_base(

  self,

  raw=False,

  force_insert=False,

  force_update=False,

  using=None,

  update_fields=None,

  )

  source link

  The 'raw' argument is telling save_base not to save any parent
  models and not to do any changes to the values before save. This
  is used by fixture loading.

• ▶ def serializable_value(self, field_name)

  Return the value of the field name for this instance. If the field is

  source link

  a foreign key, return the id value instead of the object. If there's
  no Field object with this name on the model, return the model
  attribute's value.
  
  Used to serialize a field's value (in the serializer, or form output,
  for example). Normally, you would just access the attribute directly
  and not use this method.

• ▷ def unique_error_message(self, model_class, unique_check)

  source link
• ▷ def validate_unique(self, exclude=None)

  Check unique constraints on the model and raise ValidationError if any failed.
