How can i use value from dictionary context in form_valid?
eg.
def get_context_data(self, **kwargs):
context_data = super(ProductView, self).get_context_data(**kwargs)
product_obj = Product.objects.get(id=self.kwargs['pk'])
user_id = product_obj.user_id
user_obj = User.objects.get(id=user_id)
context_data['email'] = user_obj.email
return context_data
def form_valid(self, form, **kwargs):
email = context_data['email'] # need use this value
return super(ProductView, self).form_valid(form)
CodePudding user response:
You can do it in template as hidden input:
<input type="hidden" id="id_email" name="email" value="{{ 'email' }}">
then in method:
def form_valid(self, form, **kwargs):
email = form.data['email']
return super(ProductView, self).form_valid(form)
CodePudding user response:
You can do something like this:
def form_valid(self, form, **kwargs):
context_data = self.get_context_data(form=form, **kwargs)
email = context_data['email'] # need use this value
return super(ProductView, self).form_valid(form)
but you can also do:
def form_valid(self, form, **kwargs):
for email in Product.objects.filter(id=self.kwargs['pk']).values_list('user__email', flat=True)[:1]:
context_data['email'] = user_obj.email
return super(ProductView, self).form_valid(form)
Also, if you use ProductModelForm, on form_valid you can use:
def form_valid(self, form, **kwargs):
if hasattr(form.instance, 'user'):
context_data['email'] = form.instance.user.email
return super(ProductView, self).form_valid(form)
django have many ways to do it :)
