I am actually try to post a list of values ['good','nice','happy'] to the
backend.
I have following files in my django app.
{{{
models.py
class TagModel(models.Model):
name = models.CharField(max_length=255)
class BlogModel(models.Model):
title = models.CharField(max_length=255)
tags = models.ManyToManyField(TagModel)
}}}
----
{{{
forms.py
class BlogForm(forms.ModelForm):
title = forms.CharField(widget=forms.TextInput(attrs={
'placeholder':_('Enter Blog Title'),
'class' : 'form-control border-success'
}))
blog_tags = forms.ChoiceField(widget=forms.TextInput(attrs={
"name":"blog_tags"
}))
def clean_title(self):
title = self.cleaned_data.get('title')
print(title)
return title
def clean_blog_tags(self):
//this line does not get whole list of data
tags = self.cleaned_data.get('blog_tags')
print(tags) // problem is here
return tags
class Meta:
model = PostModel
fields = ['title','blog_tags']
views.py
class create_blog(CreateView):
template_name = 'blogbackend/create_blog.html'
form_class=BlogForm
def get_form_kwargs(self):
kwargs = super(create_blog,self).get_form_kwargs()
print(kwargs)
return kwargs
}}}
Html Template
[[Image('https://i.stack.imgur.com/lzqxO.jpg')]]
What happen on template is :-
I render the title field on the view
I added a JS code on Input box , which gets value a create a hidden input
with name blog_tags
{{{
<input type="hidden" name="blog_tags" value="..." />
}}}
which is same as the filed name in forms.py file
After user submit the form
I successfully receives the both input values title and blog_tags in my
views.py file and successfully display on console with helper function
get_form_kwargs()
Data is look like this
{{{
{'initial': {}, 'prefix': None, 'data': <QueryDict:
{'csrfmiddlewaretoken':
['4Cm5mvGFv4skPJNTzRI8fKZKq9i7edQbwNmOgCPbDTtu8JQHqE5cd9rQLA8Kzhpu'],'title':
['first'],'blog_tags' : ['good','nice','happy']}>, 'instance':None}
}}}
Problem
When I am trying to access the value inside function clean_blog_tags() it
only prints list value "happy" on console
could anyone please help me to get whole list of values in clean function
Thanks GS
