Hi Gwilym, I've implemented this in a recent project, and in such a way that it works with or without Javascript enabled (the user sees a "Populate this list" button beside the sub-category list, using a <noscript> element). In my case, the setup is that each User is assigned to a number of Projects, and to a number of Tasks within each project. They can book time Entries against their assigned Tasks. On the Entry create/change forms they will see a list of their assigned Projects which will be used to populate a list of Tasks when a Project is selected. Feel free to use any of the code linked to below. If you have darcs (http://www.darcs.net) available, you can pull down the entire repository with "darcs get http://www.jonathanbuchanan.plus.com/repos/tracking/";. Otherwise, you can browse it at the following URL: Project repository: http://www.jonathanbuchanan.plus.com/repos/tracking/ Relevant files: apps/time/manipulators.py (validates choices, note special case for when Javascript is disabled) apps/time/templatetags/time_tags.py (js_task_otions - creates Javascript state mapping Projects to Tasks) apps/time/views.py (create_entry and change_entry: these determine which Tasks constitute valid choices for the selected Project) media/js/SelectUpdater.js (handles the relationship between the two lists of items) templates/time/project_updater_script.html (usage of SelectUpdater and js_task_options) The following templates include project_updater_script.html: templates/time/entry_create_form.html templates/time/entry_change_form.html Jonathan. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
