问题描述
url(r'^ article /(?P< slug> [ - \ w] +)/ $',views.ArticleView.as_view(),name ='article-detail'),
和我有这样的观点:$ b
$ b pre $ class $ ArticleView(DetailView):
model = Article
template_name ='template / article.html'
context_object_name ='article'
$ b $ def get_context_data(self,** kwargs):
context = super(ArticleView,self)。 get_context_data(** kwargs)
context ['comments'] = self.object.comment_set.filter(approved = True)
返回上下文
我已经显示了所有批准的评论(如您所见),但我不知道如何在该文章视图中创建评论表单。
我有这个 ModelForm
:
class CommentForm .ModelForm):
class Meta:
model = Comment
fields ='__all__'
和...评论模型:
class评论(models.Model):
作者= models.CharField(max_length = 100)
article = models.ForeignKey(Article,on_delete = models.CASCADE)
email = models.EmailField()
message = models.TextField(max_length = 1000)
created_at = models.DateTimeField(auto_now_add = True)
approved = models.BooleanField(default = False)
CommentForm的问题是我不知道如何'隐藏'文章和批准的字段以及如何使用ArticleView中获得的文章填充文章字段。
我尝试将 FormMixin
与 DetailView
结合,但是当我提交
评论表单,控制台显示: Me thod not Allowed(POST)
。
如何创建一个到ArticleView的表单视图?
如果你没有得到什么,请问我,我知道我的语法不好。我会尽量做到尽量清楚。
预先感谢您的解答。
class ArticleView(FormMixin,DetailView):
model = Article
template_name ='template / article.html'
form_class = CommentForm
$ b $ def get_success_url(self):
return reverse('article-detail' ,kwargs = {'slug':self.object.slug})
def get_context_data(self,** kwargs):
context = super(ArticleView,self).get_context_data(** kwargs)
context ['form'] = CommentForm(initial = {
'article':self.object
})
context ['comments'] = self.object。 comment_set.filter(approved = True)
返回上下文
$ b $ def post(self,request,* args,** kwargs):
self.object = self.get_object()
form = self.get_form()
if fo rm.is_valid():
返回self.form_valid(表单)
else:
返回self.form_invalid(表单)
$ b $ def form_valid(self,form):
form.save()
return super(ArticleView,self).form_valid(form)
在 forms.py
:
class CommentForm(forms .ModelForm):
class Meta:
model = Comment'$ b $ exclude =('admit',)
widgets = {$ b $'article':forms.HiddenInput()
}
唯一的方法是我可以...为该文章字段设置一个值(这是文章的外键)是在ArticleView中设置初始值。
如果有人有更好的选择,我很高兴看到它。
>I have this url mapping:
url(r'^article/(?P<slug>[-\w]+)/$', views.ArticleView.as_view(), name='article-detail'),
and I have this view:
class ArticleView(DetailView):
model = Article
template_name = 'template/article.html'
context_object_name = 'article'
def get_context_data(self, **kwargs):
context = super(ArticleView, self).get_context_data(**kwargs)
context['comments'] = self.object.comment_set.filter(approved=True)
return context
I've already displayed all the approved comments (as you see), but I don't know how to create a comment form inside that ArticleView.I have this ModelForm
:
class CommentForm(forms.ModelForm):
class Meta:
model = Comment
fields = '__all__'
and... Comment model:
class Comment(models.Model):
author = models.CharField(max_length=100)
article = models.ForeignKey(Article, on_delete=models.CASCADE)
email = models.EmailField()
message = models.TextField(max_length=1000)
created_at = models.DateTimeField(auto_now_add=True)
approved = models.BooleanField(default=False)
The problem with CommentForm is that I don't know how to 'hide' article and approved fields and how to fill article field with the article got in the ArticleView.
I've tried to combine FormMixin
with DetailView
but.. when I submit the comment form, console displays: Method not Allowed (POST)
.How can I create a form view into ArticleView?
If you didn't get something, please ask me, I know my grammar is bad. I will try to be clear as much as possible.
Thanks in advance for answers.
I solved it, kind of..
class ArticleView(FormMixin, DetailView):
model = Article
template_name = 'template/article.html'
form_class = CommentForm
def get_success_url(self):
return reverse('article-detail', kwargs={'slug': self.object.slug})
def get_context_data(self, **kwargs):
context = super(ArticleView, self).get_context_data(**kwargs)
context['form'] = CommentForm(initial={
'article': self.object
})
context['comments'] = self.object.comment_set.filter(approved=True)
return context
def post(self, request, *args, **kwargs):
self.object = self.get_object()
form = self.get_form()
if form.is_valid():
return self.form_valid(form)
else:
return self.form_invalid(form)
def form_valid(self, form):
form.save()
return super(ArticleView, self).form_valid(form)
in forms.py
:
class CommentForm(forms.ModelForm):
class Meta:
model = Comment
exclude = ('admitted',)
widgets = {
'article': forms.HiddenInput()
}
The only way I could... set a value for that article field (which is a foreign key for the article) was to set initial value in ArticleView.
If someone have a better alternative, I'm glad too see it.
