I have the following forms to each user profile
class UserUpdateForm(forms.ModelForm):
class Meta:
widgets = {'gender':forms.RadioSelect,}
fields = ("username", "email", "is_student",
"is_professor", "is_executive",)
model = get_user_model() #My model User
class StudentProfileForm(forms.ModelForm):
class Meta:
model = StudentProfile
fields = ('origin_education_school',current_education_school',
'extra_occupation')
class ProfessorProfileForm(forms.ModelForm):
class Meta:
model = ProfessorProfile
fields = ('occupation',)
class ExecutiveProfileForm(forms.ModelForm):
class Meta:
model = ExecutiveProfile
fields = ('occupation', 'enterprise_name',
'culturals_arthistic','ecological')
I have an URL which call to my AccountProfilesView class based view which
create an instance of the previous forms according to the user profile:
url(r"^profile/(?P<slug>[\w\-]+)/$",
views.AccountProfilesView.as_view(),
name='profile'
),
My AccountProfilesView is this:
I this moment, from the AccountProfilesView class based view I am create
the different instances of each one of these forms, according to the
user profile, then, if an user have the is_student profile their related
form will be generated, and so, of this way to is_professor and
is_executive profiles
If an user have the three profiles (is_student, is_professor,is_executive )
in one single form will be created or rendered the fields of the three
forms associated to each user profile related.
class AccountProfilesView(LoginRequiredMixin, UpdateView):
# All users can access this view
model = get_user_model()
#success_url = reverse_lazy('dashboard')
template_name = 'accounts/profile_form.html'
fields = '__all__'
def get_context_data(self, **kwargs):
context = super(AccountProfilesView,
self).get_context_data(**kwargs)
user = self.request.user
if not self.request.POST:
if user.is_student:
profile = user.get_student_profile()
context['userprofile'] = profile
context['form_student'] = forms.StudentProfileForm()
if user.is_professor:
profile = user.get_professor_profile()
context['userprofile'] = profile
context['form_professor'] = forms.ProfessorProfileForm()
print ("profesor form is", context['form_professor'])
if user.is_executive:
profile = user.get_executive_profile()
context['userprofile'] = profile
context['form_executive'] = forms.ExecutiveProfileForm()
return context
def post(self, request, *args, **kwargs):
self.object = self.get_object()
context = super(AccountProfilesView, self).post(request, *args,
**kwargs)
user = self.request.user
# if self.request.method == 'POST':
if user.is_student:
context['form_student'] = forms.StudentProfileForm(
self.request.POST)
elif user.is_professor:
context['form_professor'] = forms.ProfessorProfileForm(
self.request.POST)
elif user.is_executive:
context['form_executive'] = forms.ExecutiveProfileForm(
self.request.POST)
return context
def form_valid(self, form):
context = self.get_context_data(form=form)
user = self.request.user
user = form.save()
if user.is_student:
student = context['form_student'].save(commit=False)
student.user = user
student.save()
if user.is_professor:
professor = context['form_professor'].save(commit=False)
professor.user = user
professor.save()
if user.is_executive:
executive = context['form_executive'].save(commit=False)
executive.user = user
executive.save()
return super(AccountProfilesView, self).form_valid(form)
def get_success_url(self):
return reverse('dashboard')
And in my template, I have the following small logic:
<form method="POST">
{% csrf_token %}
{% if userprofile.user.is_student %}
<div align="center"><i>My Student Profile data</i></div>
{% bootstrap_form form_student %}
{% endif %}
{% if userprofile.user.is_professor %}
<div align="center"><i>My Professor Profile data</i></div>
{% bootstrap_form form_professor %}
{% endif %}
{% if userprofile.user.is_executive %}
<div align="center"><i>My Executive Profile data</i></div>
{% bootstrap_form form_executive %}
{% endif %}
<input type="submit" value="Save Changes" class="btn
btn-default">
</form>
>From the perspective of show the forms with the fields according to the
userprofile, this approach works, the data or fields related to the user
profile are denoted or renderised
For example this user have the three profiles and in the screen of profile
in the application, show the three forms:
<https://i.stack.imgur.com/lUfRL.jpg>
But at moment of perform update of such view screen form, (in which each
profile have their respective model/table in where their own data are
managed)
happened the following:
When I click en *Save Changes *there is an error:
File "/home/bgarcial/workspace/ihost_project/accounts/views.py", line 185,

self.request.POST)

More precisely:
<https://i.stack.imgur.com/g7dhD.png>
I think so, is that at the moment of create the form instances of the
Django forms, and I denote that the data to be included in the request and
the POST operation, this is not validated of some way
I unknown the traceback error:
BadHeaderError
Header values can't contain newlines (got '<tr><th>) .....
I've searched that error, but I don't have related information about it.
