I have a project that I am working in my Django Project I want data to be loaded from my DB to my select option. When an LCDA (Name of Local District in my app) is selected zones belonging to that LCDA will display on another select element if a Zone is selected Areas belonging to that zone will also display more like having three select element in my form.
The issue is no data is being displayed on the three element and worst still when I inspect on my browser I am not seeing the CSS links and JS links, I am using Django 3.0 but this same thing worked on Django2.1, could this be a Django version issue? If it is, I can’t afford to downgrade my app to 2.1 I followded this steps
- pip install django_select2
- I added django_select2 to my installed apps
- I added to my url config path(‘select2/’, include(‘django_select2.urls’)),
- I added this in my head {{ form.media.css }} on my base.html
- I aded jquery before body on my base.html
- I added this before body {{ form.media.js }} on my base.html
