Django formset not rendering with django-widget-tweaks - django

Question

I am getting the error 'LoginForm' object has no attribute 'as_widget' whenever I use formset. I really do not know what is the problem as the forms renders properly with normal Django forms. I am trying to see what characteristics in the formset is giving this problem with django-widget-tweaks, but up until now it is hard to figure out. I am getting the error at {% render_field field class="form-control" placeholder=field.label %} in the HTML code.
forms.py:
class LoginForm(ModelForm):
user_login = forms.HiddenInput()
prefix = 'prefix_login'
class Meta:
model = Usermie
fields = ['email', 'password']
widgets = {'password': forms.PasswordInput(),
'email': forms.EmailInput()}
views.py
def manage_articles(request):
article_formset = formset_factory(LoginForm)
book_formset = formset_factory(SignUpForm)
if request.method == 'POST':
if 'login' in request.POST:
login = article_formset(request.POST, request.FILES, prefix='login')
if login.is_valid():
email = request.POST.get('prefix_login-email', '')
password = request.POST.get('prefix_login-password', '')
# Return a user_obj object if the username and password are valid
# otherwise it will return null, the null variable is called None in python
user_obj = auth.authenticate(email=email, password=password)
# return HttpResponse("inside form if condition")
if user_obj is not None:
if user_obj.is_active:
login_usermie(request, user_obj)
return HttpResponseRedirect('/home/')
else:
# pass
return HttpResponse("Your account is inactive.")
elif 'signup' in request.POST:
signup = book_formset(request.POST, request.FILES)
if signup.is_valid():
pass
else:
login = article_formset
signup = book_formset
return render(request, 'usermie/formtest.html', {
'login': login,
'signup': signup,
})

Answer 1

login variable in template is a formset. So when you do following:
{% for field in login %}
{% render_field field class="form-control" placeholder=field.label %}
{% endfor %}
you have form as field value and not a field.
Try do this:
{% for form in login %}
{% for field in form %}
{% render_field field class="form-control" placeholder=field.label %}
{% endfor %}
{% endfor %}
