Reusing generic actions to manage relations

class aristotle_mdr.contrib.generic.views.GenericAlterForeignKey(**kwargs)

A view that provides a framework for altering ManyToOne relationships (Include through models from ManyToMany relationships) from one ‘base’ object to many others.

The URL pattern must pass a kwarg with the name iid that is the object from the model_base to use as the main link for the many to many relation.

• model_base - mandatory - The model with the instance to be altered

• model_to_add - mandatory - The model that has instances we will link to the base.

• template_name

  • optional - The template used to display the form.
  • default - “aristotle_mdr/generic/actions/alter_foreign_key.html”

• model_base_field - mandatory - the name of the field that goes from the model_base to the model_to_add.

• model_to_add_field - mandatory - the name of the field on the model_to_add model that links to the model_base model.

• form_title - Title for the form

For example: If we have a many to many relationship from DataElement`s to `Dataset`s, to alter the `DataElement`s attached to a `Dataset, Dataset is the base_model and model_to_add is DataElement.

post(request, *args, **kwargs)

Handles POST requests, instantiating a form instance with the passed POST variables and then checked for validity.

class aristotle_mdr.contrib.generic.views.GenericAlterManyToManyView(**kwargs)

A view that provides a framework for altering ManyToMany relationships from one ‘base’ object to many others.

The URL pattern must pass a kwarg with the name iid that is the object from the model_base to use as the main link for the many to many relation.

• model_base - mandatory - The model with the instance to be altered

• model_to_add - mandatory - The model that has instances we will link to the base.

• template_name

  • optional - The template used to display the form.
  • default - “aristotle_mdr/generic/actions/alter_many_to_many.html”

• model_base_field - mandatory - the field name that goes from the model_base to the model_to_add.

• form_title - Title for the form

For example: If we have a many to many relationship from DataElement`s to `Dataset`s, to alter the `DataElement`s attached to a `Dataset, Dataset is the base_model and model_to_add is DataElement.

• model_to_add_field - mandatory - the name of the field on the model_to_add model that links to the model_base model.

• ordering_field - optional - name of the ordering field, if entered this field is hidden and updated using a drag-and-drop library

• form_add_another_text - optional - string used for the button to add a new row to the form - defaults to “Add another”

• form_title - Title for the form

For example: If we have a many to many relationship from DataElement`s to `Dataset`s, to alter the `DataElement`s attached to a `Dataset, Dataset is the base_model and model_to_add is DataElement.
