django - django-taggit form

I can't comment on the used/"green ticked" answer. But I would change the Block

for m_tag in m_tags:
    object.tags.add(m_tag)

to

object.tags.add(*m_tags)

I'm not too familiar with the django taggit app, but it looks like if you want to use the same field and widget setup the app uses, you can import them from the taggit.forms (https://github.com/alex/django-taggit/blob/master/taggit/forms.py):

your models.py:

from django.db import models

from taggit.managers import TaggableManager

class Food(models.Model):
    name = models.CharField(max_length=20)

    tags = TaggableManager()

your forms.py

from taggit.forms import *

class MyForm(forms.Form):
    name = forms.CharField()
    m_tags = TagField()

The TagField will return the processed input using the parse_tags method from utils.py in the taggit app. The return looks to be a cleaned up list(set(words))

your views.py

if form.is_valid():
    name = form.cleaned_data['name']
    m_tags = form.cleaned_data['m_tags']
    object = Food(name=name)
    object.save()
    for m_tag in m_tags:
        object.tags.add(m_tag)
    return HttpResponseRedirect('/thanks/')
