Re: Question about form_valid: how to automatically set multiple fields when users input data via CreateView supported form?
Hi, Britto,
Sorry for my late reply.
Thank you so much!
I learnt a lot.
Looks like you created a function called get_context_data and put all
comment data from Comment database into context with key 'comments'.
You then called 'comments' in the template. Now I don't need
reated_name='comment' in models.py
To upload images, MEDIA_URL and MEDIA_ROOT are configured in settings.py
and urls.py
image field is added accordingly in models.py
Thank you very much!
I will keep adding features to make my first blog app!
Best regards,
Nori

Hi, Britto,
Wow, it's working as expected!
Thank you so much. (*So sorry, one more question below, please find
it!*)
Basically, you added blank=True for author field and article field in
Comment model.
In this way, I don't need to set author/article field in
CommentCreateView.
Instead, we have post function to pass around args and kwargs such as
pk.
You created form.py and author and article fields will be automatically
selected via post function.
I checked admin site and comments I made were successfully saved in
database now!
New views.py
class ArticleCommentCreateView(LoginRequiredMixin, CreateView):
model = Comment
template_name = 'article_comment_new.html'
fields = ('comment',)
# I don't need 'article' field here, because I set blank=True in
Comment model
login_url = 'login'
success_url = "/"
def post(self, request, *args, **kwargs):
pk = kwargs['pk']
form = CommentForm(request.POST, pk)
if form.is_valid():
new_comment = form.save(commit=False)
new_comment.author = request.user
new_comment.article = Article.objects.get(id=pk)
new_comment.save()
return HttpResponseRedirect('/')
**
By the way, one last thing I wanted to do on top of what we did here is
that I wanted to display all comments associated with each article.
I have been trying to take data from Comment database, but I am not
successful about it.
I am able to take out article data by using *object_list.*
*But I cannot do the same thing for comments.*
I still set related_name='comment' in Comment model.
With this related_name, *{% for comment in article.comments %} *worked
in previous program.
But now, I cannot take out comment data from database.
Sorry many questions and stealing your time.
I really appreciate your advice.
P.S.
I run shell in my terminal by typing python manage.py shell.
I did from article.models import Comment
and I did Comment.objects.all(), then I got all comments printed in my
terminal.
I read somewhere in Django docs, saying that I can implement this kind
of query in django program.
But I also read that this is not best practice in Django if I remember
correctly.
Sorry, I am looking forward to any advice to take out Comment data and
display them in the template.
Best regards,
Nori

If you don't want to display article and author in the template. Use custom
form design instead of {% form.as_p %} tag.
Something like
this will render only comment field on template. You should not remove
those fields as those are required to process form.
Share the code as zip will exam it and let you know.

Re: Question about form_valid: how to automatically set multiple fields when users input data via CreateView supported form?
set form.instance.article = request.POST.get('article')
and add article in fields too like fields = ('comment', 'article')
it should work flawlessly.

Re: Question about form_valid: how to automatically set multiple fields when users input data via CreateView supported form?
Hi, Britto,
Thank you very much for your reply!
I tried form.instance.article = *self.*request.POST.get('article'), I still
got an error shown below.

I tried other listed attributes, but seems like I could not find 'article'
information.
When I set the article field and choose an article, I get like 'article':
['2'].
Regarding user, by adding form.instance.author = self.request.user,
'author' was automatically set without choosing it in the form. But, I did
not see any author information when I tried several
print(self.request.POST.XXX)
thing.
When I tried print(self.request.user), the user was printed in terminal.
But, when I tried print(self.request.POST.user), I got an error like below.
AttributeError at /articles/2/comment/

Request URL: http://127.0.0.1:8000/articles/2/comment/

When I set the article field, and choose an article in the comment form, I
tried print(form.instance.article). Then, the article I chose was printed
in the terminal.
So, seems like form.instance.article is correct.
But how can I set the right part?
form.instance.article = self.response.X???
Where is the user information?
I successfully can access to user by self.request.user, but currently I
have no idea how to access to article information.
Sorry, any advice I can try would be really appreciated!
Looking forward to hearing advice.
Best regards,
Nori

Re: Question about form_valid: how to automatically set multiple fields when users input data via CreateView supported form?
The best way to debug it is add a print function with dir function just
before the error occurring line and see what are available attributes in
request.POST object like this print(dir("", request.POST,
"")) . Also without dir function will show what is available in
POST.
Look at the terminal after running development server and your action to
trigger error, see what are the attributes available for your request.
Probably you have to set form.instance.article = request.POST.get('article')
would work.
Regards
Britto

Question about form_valid: how to automatically set multiple fields when users input data via CreateView supported form?
I really appreciate if anybody could give me an advice about form_valid.
Here is what I want to do.
I am making a simple blog.
I am making simple features:
1) only superuser can create articles.
2) logged-in users can make comments to articles.
I followed along tutorials and mostly done.
*But last thing I want to do is that when users make comments to any
articles, I want author field and article field to be automatically set.*
*Currently, users need to choose author field and article field to make
comments as well as comment texts.*
The tutorial that I followed along uses form_valid and by using form_valid,
now I don't need to choose author.
But I have been struggling with how to automatically set article field by
using form_valid.
I have a simple models.py and views.py below.
class Article(models.Model):
title = models.CharField(max_length=255)
body = models.TextField()
date = models.DateTimeField(auto_now_add=True)
author = models.ForeignKey(
get_user_model(),
on_delete=models.CASCADE,
)
def __str__(self):
return self.title
def get_absolute_url(self):
return reverse('article_detail', args=[str(self.id)])
class Comment(models.Model): # new
article = models.ForeignKey(
Article,
on_delete=models.CASCADE,
related_name = 'comments',
)
comment = models.CharField(max_length=140)
author = models.ForeignKey(
get_user_model(),
on_delete=models.CASCADE,
)
def __str__(self):
return self.comment
def get_absolute_url(self):
return reverse('article_list')
...(not showing all)
#for comment
class ArticleCommentCreateView(LoginRequiredMixin, CreateView):
model = Comment
template_name = 'article_comment_new.html'
fields = ('comment',)
login_url = 'login'
def form_valid(self, form):
form.instance.author = self.request.user
*form.instance.article = self.request.article*
return super().form_valid(form)
I keep getting errors with this code.
I know that *form.instance.article = self.request.article* is something
wrong, but I am having hard time to figure out how to set article field to
be automatically set.
Please give any advice about this.
I really appreciate.
Looking forward to hearing from anyone.
Best regards,
Nori
