cascade_save(**kwargs)#

Recursively save any references and generic references on the document.

clean()#

Hook for doing document level data cleaning (usually validation or assignment) before validation is run.

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.

Clears the field from the document.

Parameters:

field_name – the field name

Raises:

ValueError – if the field does not exist

classmethod compare_indexes()#

Compares the indexes defined in MongoEngine with the ones existing in the database. Returns any missing/extra indexes.

copy(new_id=False)#

Returns a deep copy of the document.

Parameters:

new_id (False) – whether to generate a new ID for the copied document. By default, the ID is left as None and will be automatically populated when the document is added to the database

copy_with_new_id()#
classmethod create_index(keys, background=False, **kwargs)#

Creates the given indexes if required.

Parameters:
  • keys – a single index key or a list of index keys (to construct a multi-field index); keys may be prefixed with a + or a - to determine the index ordering

  • background – Allows index creation in the background

delete(signal_kwargs=None, **write_concern)#

Delete the Document from the database. This will only take effect if the document has been previously saved.

Parameters:
  • signal_kwargs – (optional) kwargs dictionary to be passed to the signal calls.

  • write_concern – Extra keyword arguments are passed down which will be used as options for the resultant getLastError command. For example, save(..., w: 2, fsync: True) will wait until at least two servers have recorded the write and will force an fsync on the primary server.

classmethod drop_collection()#

Drops the entire collection associated with this Document type from the database.

Raises OperationError if the document has no collection set (i.g. if it is abstract)

classmethod ensure_indexes()#

Checks the document meta data and ensures all the indexes exist.

Global defaults can be set in the meta - see guide/defining-documents

By default, this will get called automatically upon first interaction with the Document collection (query, save, etc) so unless you disabled auto_create_index, you shouldn’t have to call this manually.

This also gets called upon every call to Document.save if auto_create_index_on_save is set to True

If called multiple times, MongoDB will not re-recreate indexes if they exist already

Note

You can disable automatic index creation by setting auto_create_index to False in the documents meta data
