Django Form, how to get further model info for ModelChoiceField
I have 3 models that are related to eachother. A showing has the 'film' and 'screen' foreignkeys that link to Film and Screen. I'm trying to setup a webpage so that you can view information on a showing that is already setup, and edit it from dropdowns of what films and screens are available.

how to add Comment form inside a post detailed
Is there any way I can add a comment form inside a post's details? I have a view that shows a model object, and I want to allow users to comment on that view.

Django query __in filter on subquery joined over multiple fields without foreignkey

The table constists of activities of people. Each people has multiple activities so multiple rows in this table. 1) First access is to find for a set of given filters (like the name of the acitivity and the age of the person) which persons activities fit the filters and per person what is its oldest acitivity fitting the filters. I call that oldest-date "start_date". On SQL this could look like: select m2.person_id, min(m2.date_current) as start_date from my_table m2 where [...] group by person_id With this query I found a sub-set of people with their oldest filtered-activity (so there may be also older activities which do not fit the filters above) Sample A sample would be to find all people ever did taking drugs plus the date when it happened first. 2) Second access is to get for every person found all its … -

How to deal with Django Cascade deleted objects in django-simple-history?
I have a problem with django-simple-history when I use cascade deletion on objects. I have several tables in my database that inherit from other tables, so I’ve set the deletion to cascade. The problem is that when I want to query Historical Objects generated by django-simple-history, I do have the one in the parent table, but for objects in the children table, that were automatically deleted by Django, I this error : MyApp.models.parentTable_object.DoesNotExist: parentTable_object matching query does not exist. If I understand the problem, django-simple-history tried to create a Historical object for my deleted object but failed because it needed the parent object it inherited and that no longer exists at this point. I can’t do without cascading so I hope it’s possible because django-simple-history has met all my expectations so far.
