Model object has no attribute save

Question

This is the model I've defined:

class Post(models.Model):
    user = models.ForeignKey(MSUser)
    upvote_count = models.IntegerField()
    post_status = models.IntegerField(choices = POST_STATUS)
    title = models.CharField(max_length=200,null = True,blank = True)
    content = models.CharField(max_length=1000,null = False,blank = False)
    created_at = models.DateTimeField(auto_now_add=True, null=True)
    updated_at = models.DateTimeField(auto_now=True, null=True)

    def __unicode__(self):
        return self.content

    def get_user(self):
        return self.user.__unicode__()

    def save(self, **kwargs):
        super(Post, self).save(**kwargs)

Here is the view:

class Post (View):
    @method_decorator(csrf_exempt) # To be removed
    def dispatch(self, request, *args, **kwargs):
#         Placeholder for fine grained permission system to prevent unwarranted GET/POST/PUTS
#          Check request.user properties (like group etc) and request.method 
#             return HttpResponseForbidden()
        return super(Post, self).dispatch(request, *args, **kwargs)

    def get(request):
        pass

    def post(self, request):
        responseMessage = {}  
        user = request.user
        if user.is_authenticated():
            title = request.POST.get('title', None)
            content = request.POST.get('content', None)
            if title is None or content is None:
                responseMessage['status'] = 'failure'
                responseMessage['message'] = 'Mandatory data is missing.'
                return HttpResponse(json.dumps(responseMessage))
            else:
                newPost = Post(user = user,
                               title = title,
                               content = content,
                               post_status = PS_CREATED,
                               upvote_count = 0)
                newPost.save()
                responseMessage['status'] = 'success'
                responseMessage['message'] = 'Post created successfully'
                responseMessage['server_id'] = newPost.id
                return HttpResponse(json.dumps(responseMessage))

When sending a request from Postman I keep getting the following error:

AttributeError: 'Post' object has no attribute 'save'

What am I doing wrong?

Answer 1

Your view class and the model class have the same name ie Post .

So, when you do Post(user=..) in your view, it tries to create the Post view object and then call .save() on it whereas it should have created the Post model object and saved it.

To solve your problem, you need to change your view class name to something else.

Try changing

class Post(View): 

to something like

class PostView(View): 

Answer 2

You have duplicated objects named Post which you got mixed. It looks like you are trying to save the View object instead of the Model object.
