Karen,
Spot on with the first positional argument I think, but I now get the
error:
form = TweetForm(instance=obj)
TypeError: __init__() got an unexpected keyword argument 'instance'
Here is the view:
if request.method == 'POST':
form = TweetForm(request.POST)
etc.
elif isinstance(obj, TweetLog):
form = TweetForm(instance=obj) <----- had TweetForm(obj)
before!
else:
default_taglist = request.session.get('taglist', '')
form = TweetForm(initial = {'tweet_taglist' :
default_taglist}) # An unbound form
return form
And the form:
class TweetForm(forms.Form):
tweet = forms.CharField(widget=TweetFieldWidget(), required=True)
tweet_taglist = forms.CharField(max_length=100, required=False)
process_backwards = forms.BooleanField(required=False)
attached_notes = forms.CharField(widget=forms.Textarea,
required=False)
attached_url = forms.URLField(required=False)
attached_file = forms.FileField(required=False)
attached_image = forms.ImageField(required=False)
class Media:
js = ('/js/jquery.js', '/js/jquery-ui.min.js','js/
jeditable.js','js/tweetform.js', 'js/jquery-ui.tabs.js')
css = { 'all': ('/css/jquery-ui.css','/css/smoothness/jquery-
ui-1.7.2.custom.css') }
class Meta :
model = TweetLog
fields =
('tweet','attached_notes','attached_url','attached_file','attached_image')
