How to position inlines in Django Admin in the list_display property?

I have two tables related Quiz and Difficulty_level:

I have created inline in admin.py like this:

class DifficultyLevelInline(admin.TabularInline):
    model = DifficultyLevel

and included in QuizAdmin

To arrange the list order, I would do:

  list_display = ('name', 'description', 'publication_date', 'category', 'is_active', 'is_premium')

How can I add inlines in the list_display order. I want to display The DifficultyLevelInline before category.

I found an app for exactly this: https://github.com/robertkovac/django-fieldsets-with-inlines

class MyModelAdmin(FieldsetsInlineMixin, admin.ModelAdmin):
    ...
    fieldsets_with_inlines = [
        (None, {
            'fields': [
                'name',
                'slug',
            ],
        }),
        RelatedThingInline,
        ('Moar Feelds', {
            'is_great',
            'is_neet',
        }),
    ]

Works for me on Django 4.1.

I found a solution here: https://blog.devgenius.io/django-admin-dynamic-inline-positioning-7208596479ce

class MyAdmin(admin.ModelAdmin):
    list_display = ('name', 'description', 'difficulty_level_inline', 'publication_date', 'category', 'is_active', 'is_premium')
    inlines = (DifficultyLevelInline,)

    def difficulty_level_inline(self, *args, **kwargs):
        context = getattr(self.response, 'context_data', None) or {}
        inline = context['inline_admin_formset'] = context['inline_admin_formsets'].pop(0)
        return get_template(inline.opts.template).render(context, self.request)

    def render_change_form(self, request, *args, **kwargs):
      self.request = request
      self.response = super().render_change_form(request, *args, **kwargs)
      return self.response

  • Suppose here is your inline model:
# models.py
from django.contrib.auth.models import Group


class MoreGroup(models.Model):
    group = models.OneToOneField(Group, on_delete=models.CASCADE, related_name='more_group')
    explain = models.CharField(verbose_name="explain_info", max_length=64, blank=True, null=True)
    active = models.BooleanField(verbose_name="is_actived", default=True, blank=True, null=True)
  • then do this:
# admin.py
from . import models


class MoreGroupInline(admin.StackedInline):
    model = models.MoreGroup
    can_delete = False
    verbose_name_plural = 'more_info'


class MyGroupAdmin(GroupAdmin):
    list_display = ['id', 'name', 'get_inline_info']
    def get_inline_info(self, obj) -> str:
        mg = models.MoreGroup.objects.filter(group=obj)
        if mg.count():
            return mg[0].explain
        else:
            return '-'
    get_inline_info.short_description = 'explain_info'

admin.site.register(models.Group, MyGroupAdmin)

Grapelli supports it: https://django-grappelli.readthedocs.org/en/latest/customization.html#rearrange-inlines

Basically, it uses a placeholder via fieldsets and then moves them HTML via JavaScript: https://github.com/sehmaschine/django-grappelli/blob/master/grappelli/templates/admin/change_form.html#L90-96 (search for placeholder, if the lines do not match anymore).

The same can be done by injecting custom javascript yourself (with or without using fieldsets as placeholders).

Unfortunately this is not possible using the default template.

If you take a look at change_form template:

https://github.com/django/django/blob/master/django/contrib/admin/templates/admin/change_form.html

You can see that inlines are always rendered after fieldsets.

One way to get around this would be to use other template:

class MyAdmin(admin.ModelAdmin):
    list_display = ('name', 'description', 'publication_date', 'category', 'is_active', 'is_premium')
    inlines = (DifficultyLevelInline,)
    change_form_template = "my_change_form.html"
