EditFormSet
(**kwargs)[source]¶ Derived from FormSet. Here we have, additionally, buttons for creating new records, and for copying, saving and clearing them. This FormSet makes it possible to write into the collection.

class
cute_mongo_forms.container.base.
FormSet
(**kwargs)[source]¶ Group of forms. Each form corresponds to a different Row class. Only one type of form is visible at a time.
Parameters at instantiation:
Parameters: collection – Collection object with row classes and the document collection -
chooseForm_slot
(element, element_old)[source]¶ Calling this slot chooses the form to be shown
Parameters: - element – an object that has _id and classname attributes
- element_old – an object that has _id and classname attributes
This slot is typically connected to List classes, widget attribute’s, currentItemChanged method (List.widget is QListWidget that has currentItemChanged slot), so the element and element_old parameters are QListWidgetItem instances with extra attributes “_id” and “_classname” attached.
Queries the database for element._id
