db.models.options.Options.get_field()

Options.get_field(field_name) [source]

Returns the field instance given a name of a field.

field_name can be the name of a field on the model, a field on an abstract or inherited model, or a field defined on another model that points to the model. In the latter case, the field_name will be the related_name defined by the user or the name automatically generated by Django itself.

Hidden fields cannot be retrieved by name.

If a field with the given name is not found a FieldDoesNotExist exception will be raised.

# A field from another model that has a relation with the current model
>>> User._meta.get_field('logentry')

# A non existent field
