Class FileField

Declaration

Methods

• ▶ def __init__(self, verbose_name=None, name=None, upload_to='', storage=None, **kwargs) override

  source link

  This method overrides django.db.models.fields.Field.__init__.

  Overrides

  This method is overriden in:

  • django.db.models.fields.files.ImageField
• ▶ def check(self, **kwargs) override

  source link

  This method overrides django.db.models.fields.Field.check.

  Overrides

  This method is overriden in:

  • django.db.models.fields.files.ImageField
• ▶ def contribute_to_class(self, cls, name, **kwargs) override

  inherited doc Register the field with the model class it belongs to.

  source link

  This method overrides django.db.models.fields.Field.contribute_to_class.

  If private_only is True, create a separate instance of this field
  for every subclass of cls, even if cls is not an abstract model.

  Overrides

  This method is overriden in:

  • django.db.models.fields.files.ImageField
• ▶ def deconstruct(self) override

  inherited doc Return enough information to recreate the field as a 4-tuple:

  source link

  This method overrides django.db.models.fields.Field.deconstruct.

  * The name of the field on the model, if contribute_to_class() has
     been run.
   * The import path of the field, including the class:e.g.
     django.db.models.IntegerField This should be the most portable
     version, so less specific may be better.
   * A list of positional arguments.
   * A dict of keyword arguments.
  
  Note that the positional or keyword arguments must contain values of
  the following types (including inner values of collection types):
  
   * None, bool, str, int, float, complex, set, frozenset, list, tuple,
     dict
   * UUID
   * datetime.datetime (naive), datetime.date
   * top-level classes, top-level functions - will be referenced by their
     full import path
   * Storage instances - these have their own deconstruct() method
  
  This is because the values here must be serialized into a text format
  (possibly new Python code, possibly JSON) and these are the only types
  with encoding handlers defined.
  
  There's no need to return the exact way the field was instantiated this
  time, just ensure that the resulting field is the same - prefer keyword
  arguments over positional ones, and omit parameters with their default
  values.

  Overrides

  This method is overriden in:

  • django.db.models.fields.files.ImageField
• ▶ def formfield(self, **kwargs) override

  inherited doc Return a django.forms.Field instance for this field.

  source link

  This method overrides django.db.models.fields.Field.formfield.

  Overrides

  This method is overriden in:

  • django.db.models.fields.files.ImageField
• ▶ def generate_filename(self, instance, filename)

  Apply (if callable) or prepend (if a string) upload_to to the filename,

  source link

  then delegate further processing of the name to the storage backend.
  Until the storage layer, all file paths are expected to be Unix style
  (with forward slashes).

• ▶ def get_internal_type(self) override

  source link

  This method overrides django.db.models.fields.Field.get_internal_type.

• ▶ def get_prep_value(self, value) override

  inherited doc Perform preliminary non-db specific value checks and conversions.

  source link

  This method overrides django.db.models.fields.Field.get_prep_value.

• ▶ def pre_save(self, model_instance, add) override

  inherited doc Return field's value just before saving.

  source link

  This method overrides django.db.models.fields.Field.pre_save.

• ▶ def save_form_data(self, instance, data) override

  source link

  This method overrides django.db.models.fields.Field.save_form_data.
