django admin many-to-many intermediary models using through= and filter_horizontal

Question

This is how my models look:

class QuestionTagM2M(models.Model):
    tag = models.ForeignKey(\'Tag\')
    question = models.ForeignKey(\'Question\')
    date_         


        

Answer 1

The docs may have changed since the previous answers were posted. I took a look at the django docs link that @Irfan mentioned and it seems to be a more straight forward then it used to be.

Add an inline class to your admin.py and set the model to your M2M model

class QuestionTagM2MInline(admin.TabularInline):
    model = QuestionTagM2M
    extra = 1

set inlines in your admin class to contain the Inline you just defined

class QuestionAdmin(admin.ModelAdmin):
    #...other stuff here
    inlines = (QuestionTagM2MInline,)

Don't forget to register this admin class

admin.site.register(Question, QuestionAdmin)

After doing the above when I click on a question I have the form to do all the normal edits on it and below that are a list of the elements in my m2m relationship where I can add entries or edit existing ones.
