Hi Daniel,
i change it to instance, but still got other errors :
def myadmin_change_post(request,
template_name='blog/admin/change_post.html'):
try:
id= request.GET.get('id','4')
except ValueError:
id=1
#post = get_object_or_404(Post,pk=id)
post = Post.objects.get(pk=id)
form = AdminPostForm(instance=post)
return render_to_response(template_name,locals(),context_instance =
RequestContext(request) )
the form :
class AdminPostForm(forms.Form):
cat_choices = [('private','private')]
title =
forms.CharField(widget=forms.TextInput(attrs={'size':'20','value':'','class':''}),label='Title')
content=
forms.CharField(widget=forms.Textarea(attrs={'cols':'40','rows':'5'}),label='Content')
slug =
forms.CharField(widget=forms.TextInput(attrs={'size':'20','class':''}),label='Slug')
is_publish = forms.BooleanField(label='Publish')
categories = forms.ChoiceField(choices=cat_choices)
created_at =
forms.DateTimeField(widget=forms.DateTimeInput(),label='Created at')
modified_at =
forms.DateTimeField(widget=forms.DateTimeInput(),label='Modified at')
any clue where the error migh be..
