Q:

django/taggit - unhashable type: 'list'

I'm using django-taggit (see here). This is what I have:
forms.py
from taggit.forms import *

    class MyForm(forms.Form):
        title = forms.CharField()
        my_tags = TagField(max_length=800, widget=forms.TextInput(attrs={'class':'myTags'}))

views.py
       if 'submit_button' in request.POST:
            form = MyForm(request.POST)
            if form.is_valid():
               cd = form.cleaned_data 
               f_title = cd['title']
               f_my_tags = cd['my_tags']

               p = MyData.objects.create(title=f_title)   
               p.tags.add(f_my_tags)
               p.save()

mytemplate.html
{{ form.my_tags.errors }}
{{ form.my_tags }}

Not sure why I get unhashable type: 'list' when I use p.tags.add(f_my_tags) in my views.py. Any ideas? Thank you!

A:

You need to either add tags individually:
map(p.tags.add, cd['my_tags'])

this is equivalent to:
for tag in cd['my_tags']:
    p.tags.add(tag)

or pass them as positional arguments to tags.add:
p.tags.add(*cd['my_tags'])

this being equivalent to:
    p.tags.add(cd['my_tags'][0], cd['my_tags][1]... )
