Custom filter for filter_horizontal admin in django
I have the following models where a deck have a many to many relationship with problems and problems can have tags
from django.utils import timezone
from django.db import models
from taggit.models import TaggedItemBase
from taggit.managers import TaggableManager
# Create your models here.
class TaggedProblem(TaggedItemBase):
content_object = models.ForeignKey('Problem', on_delete=models.CASCADE)
class Problem(models.Model):
title = models.CharField(max_length=200)
body = models.CharField(max_length=10000)
pub_date = models.DateTimeField("date published", default=timezone.now())
tags = TaggableManager(through=TaggedProblem)
class Meta:
verbose_name = "problem"
verbose_name_plural = "problems"
def __str__(self):
return self.title
class Deck(models.Model):
name = models.CharField(max_length=200)
problems = models.ManyToManyField(Problem)
def __str__(self):
return self.name
then for the admin i have the following
from django.contrib import admin
# Register your models here.
from .models import Problem,Deck
class DeckAdmin(admin.ModelAdmin):
filter_horizontal = ('problems',)
admin.site.register(Deck, DeckAdmin)
admin.site.register(Problem)
well what i want to do is to have a custom filter to filter the available problems, the filter must be an interface where i can include and exclude tags associated with the problems, so i want to replace the filter search box with something like this
so i can filter the problems by tags and then add then to the deck, how can i achieve that functionality?, i am new to django and have no idea how to proceed
