How to Encrypt Password before saving it to User Model Django?
I've created a user-signup page which adds users to User Model in Django But when the data is saved, the Password is not encrypted, i.e. stored as Text only. This creates a problem when the user tries to log in (as Django tries to Decrypt the original password, and they both don't match). Also, I'm extending the User Model so as to add more information about the users which is saved in the Profile Model (Using a One-To-One Link) views.py def user_signup(request): if request.method == "POST": user_form = userSignup(request.POST) phone = request.POST['phone'] address = request.POST['address'] pincode = request.POST['pincode'] if user_form.is_valid() : user = user_form.save() auth.login(request,user) userdata = User.objects.all() for userinfo in userdata: if userinfo.username == user.username: user_id=user.id update_data = Profile.objects.get(pk = user_id) update_data.address=address update_data.phone=phone update_data.pincode=pincode update_data.save() return redirect('/') else: return HttpResponse(" SIGNUP FAILED") else: form = userSignup() profile_form = userSignup_profile() return render(request,"user_signup.html",{'form':form, 'profile_form':profile_form}) def user_logout(request): auth.logout(request) return redirect('/') user_signup.html <body> <form action="user_signup" method="POST"> {% csrf_token %} {{form.as_p}} {{ profile_form.as_p}} <button class="primary" type="submit" >SIGNUP </button> </form> </body> Models.py class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) phone = models.CharField(max_length=10) address = models.TextField(max_length=200) pincode = models.IntegerField() forms.py class userSignup(forms.ModelForm): password = forms.CharField(max_length=50, widget = forms.PasswordInput()) class Meta: model = User fields = ('first_name', 'last_name','username', … -
Why can't I access subclass type for my Django model instances?
I have something like this: class Cat(models.Model): #some fields class SiameseCat(Cat): #some additional fields for cat in pet_store.cats.all(): print(isinstance(cat, SiameseCat)) print(type(cat)) Even when my instantiated SiameseCats are visible under a separate heading on the django admin page, I always get "False, Cat" printed to the terminal for each cat in the pet store. If I try to print(cat.siamese_only_field), I get an attribute error. I need to access and output the siamese_only_field for my project to work. Also, this whole thing is generally a head scratcher and I'd like to know what I'm doing wrong. Why can't I access the model subclass of an object as expect? -

how to redirect to a profile page and see the data of the logged in user in Django?
I have been working on a small project, and it was developing smoothly until I got a road block. However, I am not able to route to the profile page. My website workflow is as below: 1) user sign up and redirect to login screen once registration successful. 2) user login and now he/she sees a form, where he/she needs to fill in mandatory fields 3) save and then either click on "profile" link(in the navbar) to see the profile data, or "save" button will redirect to the profile page automatically. point 3) is not working. For now I have a hyperlink in the NavBar for "profile". But its not doing anything though I have written the GET method. May be I am not fetching the data properly.

How can I create a Django model in views.py?
In a DetailView page for object "Patient", I have a form. When the form is filled and submitted, I want to create a "Location" object. Then, I want to create a ForeignKey pointing to the "Patient" object that we are looking at in the DetailView. As you can see, if the form is valid, I call the model constructor, save the information and connect it to the patient object. However when I check Django Admin, I can't see a new object created. I totally improvised as I couldn't find examples online. Is this the way to do it? class PatientDetailView(DetailView, FormMixin): model=Patient form_class = PastLocationForm #template_name = 'patient_detail.html' def get_success_url(self): return reverse('patient_detail', kwargs={'pk': self.object.pk}) def post(self, request, *args, **kwargs): if not request.user.is_authenticated: return HttpResponseForbidden() self.object = self.get_object() form = self.get_form() if form.is_valid(): pastLocationDetail = Location() setattr(pastLocationDetail,'location',str(form.cleaned_data['location']).split(',')[0]) setattr(pastLocationDetail,'address',str(form.cleaned_data['location']).split(',')[1].split(', ')[0]) setattr(pastLocationDetail,'district',str(form.cleaned_data['location']).split('District: ')[1].split(',')[0]) setattr(pastLocationDetail,'grid_x',str(form.cleaned_data['location']).split('Coordinates: (')[1].split(', ')[0]) setattr(pastLocationDetail,'grid_y',str(form.cleaned_data['location']).split('Coordinates: (')[1].split(', ')[1][:-1]) setattr(pastLocationDetail,'date_from',form.cleaned_data['date_from']) setattr(pastLocationDetail,'date_to',form.cleaned_data['date_to']) setattr(pastLocationDetail,'details',form.cleaned_data['details']) setattr(pastLocationDetail,'patient', self.object) return self.form_valid(form) else: return self.form_invalid(form) Location model class Location(models.Model): patient = models.ForeignKey(Patient, related_name='locations', on_delete=models.CASCADE, null=True, blank=True) . .
