I'm working on a Django form to add user data, but when I click the submit button, nothing happens: there's no redirect to '/' and no data is saved to the database.
I expect the form to auto-fill datetime fields and then redirect back to the previous page once the data is successfully submitted. Below are the relevant code snippets for the HTML form, views, models, forms, and URLs.

I've identified several issues with your form submission process that are preventing the data from being saved and the redirect from happening. Let's address them one by one:
In your HTML form, the action attribute is empty:
HTML<form action="" method="POST">
This means the form is submitting to the current URL, but you need to ensure this URL is mapped to your UserAjouter
view.
Your URLs configuration doesn't include a path for the UserAjouter
view:
PYTHONurlpatterns = [ path("Groupe_Users/add/", views.GroupeAjouter, name='GroupeAjouter'), ]
You need to add a URL pattern for the UserAjouter
view.
There are several issues with your form fields:
The PROFILSIGN
field has the wrong name attribute in the HTML:
HTML<input name="Activer" type="text" id="PROFILSIGN" ...>
It should be:
HTML<input name="PROFILSIGN" type="text" id="PROFILSIGN" ...>
The PICTURE
field uses type="image"
which is incorrect for file uploads. It should be type="file"
.
Your form likely has validation errors that are preventing it from being saved. The view doesn't print form errors when validation fails:
PYTHONif form.is_valid(): form.save() return redirect('/') else: print("") # This should print form.errors
You're trying to set attributes on the form instance before creating it with POST data:
PYTHONform.created_at = datetime.now() form.updated_at = datetime.now() form.UTIL_CREATION = settings.WCURUSER form.UTIL_MODIF = settings.WCURUSER form.Soc_sigle = settings.WSOCGEN form = f_utilisateur_userForm(request.POST) # This creates a new form instance
Here's how to fix these issues:
PYTHONurlpatterns = [ path("Groupe_Users/add/", views.GroupeAjouter, name='GroupeAjouter'), path("User/add/", views.UserAjouter, name='UserAjouter'), # Add this line ]
HTML<form action="{% url 'UserAjouter' %}" method="POST" enctype="multipart/form-data">
Correct the name attribute for PROFILSIGN and change the PICTURE input type.
PYTHONdef UserAjouter(request): # ... existing code ... form = f_utilisateur_userForm() if request.method == "POST": # Create the form with POST data first form = f_utilisateur_userForm(request.POST, request.FILES) if form.is_valid(): # Create but don't save the new instance new_user = form.save(commit=False) # Set the additional fields new_user.created_at = datetime.now() new_user.updated_at = datetime.now() new_user.UTIL_CREATION = settings.WCURUSER new_user.UTIL_MODIF = settings.WCURUSER new_user.Soc_sigle = settings.WSOCGEN # Now save the instance new_user.save() # Save many-to-many relationships if any form.save_m2m() return redirect('/') else: print("Form errors:", form.errors) # ... rest of the code ...
Make sure your form has enctype="multipart/form-data"
and that you're passing request.FILES
to the form when handling file uploads.
Here's the corrected view function:
PYTHONdef UserAjouter(request): pk = request.user.id groupe = f_groupe_user.objects.get(IDF_GROUPE_USER=pk) scuser = request.user.id aze = "Ajout utilisateur" sEtat = "crea" utilisateur = groupe.f_utilisateur_set.all() groupes = f_groupe_user.objects.all() print(f"La valeur du groupe dans GroupeAjouter est : {utilisateur}") print(f"La valeur du scuser est : {scuser}") if request.method == "POST": form = f_utilisateur_userForm(request.POST, request.FILES) print("Lheure locale est:") print(localize(datetime.now())) print(request.method) if form.has_changed(): print("The following fields changed: %s" % ", ".join(form.changed_data)) if form.is_valid(): new_user = form.save(commit=False) new_user.UTIL_CREATION = settings.WCURUSER new_user.UTIL_MODIF = settings.WCURUSER new_user.Soc_sigle = settings.WSOCGEN new_user.save() form.save_m2m() return redirect('/') else: print("Form errors:", form.errors) else: form = f_utilisateur_userForm() context = {'form': form, 'groupe': groupe, 'aze': aze, 'sEtat': sEtat, 'utilisateur': utilisateur, 'scuser': scuser, 'groupes': groupes} return render(request, 'appMenuAdministrator/L_liste_GroupeUtilisateur/FicheCreaUser.html', context)
By implementing these changes, your form should properly save data to the database and redirect to the home page after successful submission.
