Question

i created a form to save a post into db for my blog project. I’ve designed index page. now i am tryin to create a form to create new posts. before that i was using ‘ manage.py shell’

here is my view :

def addpost(request):
    form = addForm()
    if request.method=="POST":
        titleform = request.POST['title']
        bodyform = request.POST['body']
        checkform = request.POST['isdraft']
        if form.is_valid():
                n = Post(title = titleform, body = bodyform, isdraft=checkform)
                n.save()

                return HttpResponseRedirect('/admin/')
    else:
        pass
    return render(request,'userside/add.html',{'form':form,})

my model.py:

class Post(models.Model):
    title = models.CharField(max_length = 100)
    body  = models.TextField()
    slug = AutoSlugField(populate_from='title',unique=True)
    posted = models.DateField(auto_now_add=True)
    isdraft = models.BooleanField()
    def __unicode__(self):
        return self.title

    @permalink
    def get_absolute_url(self):
        return ('view_blog_post',None, {'postslug':self.slug})

class addForm(forms.Form):
    title = forms.CharField(max_length=100)
    body  = forms.CharField(widget=forms.Textarea)
    isdraft = forms.BooleanField()

if i submit form as ‘isdraft’ field is False(unchecked) ; it gives error like:

MultiValueDictKeyError at /admin/addpost/

“Key ‘isdraft’ not found in “

and if i submit the form as ‘isdraft’ field is True(checked) ; it gives nothing. just refreshing form. no adding data into db.

i am doing sth wrong..

thank you

edit : Dmitry Beransky’s answer worked for checkbox error. but it still doesnt add any data into db. just refreshes the form.

Answer 1

The whole point of using a form is that it takes care of validation and cleaning, that is converting values to the proper data types. That’s why you should be accessing form.cleaned_data rather than reques.POST, and you should be doing it inside the if form.is_valid() check.

Edit

I’ve just noticed that you’re never passing request.POST to the form. So form.is_valid() will never be true.

Please go back and read the documentation about using a form in a view.
