First a short description of the issue: I'm trying to create a module-system similar to the one in Joomla!, where modules (small information-widgets) can be shown in different positions on different pages of the website. I'm using the django-treemenus app for the menu-structure of the website, this is comprised of two models: Menus and MenuItems.
When the user creates a module in the Django-admin he should be able to pick the pages it's shown on from a SelectMultiple-list. For this, I've created a Many-to-Many field that links Modules with MenuItems. So far so good. The MenuItems are shown ordered by ID, as is to be expected. However, I would like to show them ordered by Menu, and also indented according to their level in the tree-structure. The MenuItems-model contains methods to generate such a structure, I just don't know what the best way to populate the SelectMultiple-field with it is. After some googling and searching in this group, I think I've found two possible solutions: 1. Create a custom-widget based on SelectMultiple and replace self.choices with my own tuples. The problem I see with this is that it will query the database unnecessarily, once to populate the field in the default way and then when I run my own queries. Is there a way to avoid this? Where are the choices generated? 2. Instead of a Many-to-Many field, maybe use some other field (CommaSeparatedInteger?) and make a ModelForm that shows a MultipleSelect-Widget that I populate dynamically. The problem here is that I'd rather prefer not to lose the relationship between Modules and MenuItems that the M-to-M field creates. Sorry for this lengthy first post. Anybody have any idea what the best solution is? Is there something I haven't considered?
