How to edit user profile in Django
I'm trying to create an "Edit Profile" form in the fronted. What happens is that my form(i'm not 100% sure) tries to create a user instead of finding the current user and update his profile. So I think that's the issue. Checked many questions here but none was clear enough. The fields I'm trying to edit are email(to be checked if email already exisit), Name, user type, and password. below is the code for forms.py class ProfileForm(forms.ModelForm): password1 = forms.CharField(label='Password', widget=forms.PasswordInput) password2 = forms.CharField(label='Confirm Password', widget=forms.PasswordInput) class Meta: model = User fields = ('full_name', 'active', 'admin','email','user_type') def clean_password2(self): # Check that the two password entries match password1 = self.cleaned_data.get("password1") password2 = self.cleaned_data.get("password2") if password1 and password2 and password1 != password2: raise forms.ValidationError("Passwords don't match") return password2 def save(self, commit=True): # Save the provided password in hashed format user = super(ProfileForm, self).save(commit=False) user.set_password(self.cleaned_data["password1"]) # user.active = False # send confirmation email if commit: user.save() return user code for views.py def profile(request): user = User.objects.filter(email = request.user) # form = ProfileForm(user.values().first()) if request.method == 'POST' : form = ProfileForm(request.POST) if form.is_valid(): form.save(commit=True) form = ProfileForm(user.values().first()) # print(user) context = { 'object_list': user, 'form': form } return render(request, 'userpanel/profile.html',context) Thanks in advance -
How to count the distinct of model_set in Django?
I've looked into this question, but I think it's different. Let me explain a bit further. I have a serializer called DetailTrackSerializer to serialize my Track model, and I've nested a TaggedSerializer in DetailTrackSerializer. class DetailTrackSerializer(serializers.ModelSerializer): id = serializers.IntegerField(read_only=True) title = serializers.CharField(max_length=120) link = serializers.URLField(max_length=120) tagged_set = TaggedSerializer(many=True) artist = ArtistSerializer() class Meta: model = Track fields = ('id', 'artist', 'title', 'link', 'tagged_set',) class TaggedSerializer(serializers.ModelSerializer): tag = TagSerializer() class Meta: model = Tagged fields = ('tag',) class TagSerializer(serializers.ModelSerializer): class Meta: model = Tag fields = ('name',) Currently, this DetailTrackSerializer is returning a json like this { "tracks": [ { "id": 168, "artist": { "id": 163, "name": "Gob" }, "title": "Face the Ashes", "link": "", "tagged_set": [ { "tag": { "id": 1356, "name": "punk rock" } }, { "tag": { "id": 1356, "name": "punk rock" } }, { "tag": { "id": 1356, "name": "punk rock" } }, ... The list goes on, if there are 100 "punk rock" tag in this track, it will shows up 100 times.

Passing multiple arguments into Django's filter()
Based on user input I need to pass custom arguments into Django filter. Something along the lines of the following: q = Question.objects.all() a = q.filter(O_Stat__icontains = "Active", Ll_Name__icontains = "fruit") I tried setting the arguments to string: f = 'Operating_Status__icontains = "Active", Legal_Name__icontains = "fruit"' a = q.filter(f) Get a stack trace error. Is there a better solution then to pass every possible field into the filter ? #Like This a = q.filter(O_Stat__icontains = UserIn1, Ll_Name__icontains = UserIn2) Regards. -

Django - looking for architectural advice for my project
First of all, I want to say that I'm really a novice with Django, and looking for some architectural advice for my project. I have a front-end template that looks like this: When a user clicks "Save" button, the information in the input fields needs to be saved into the database. I don't want my page to be refreshed when I click "Save" button, because only the information that belongs to the section will be sent. (however, if this needs some AJAX plugin, I can give it up on that for now. Primary importance for now is just connecting this front-end with PostgreSQL database) Ex: clicking Save in "Overall BHA" section will only save inputs in the "Overall BHA" into the database without refreshing the page. And the same process for "Drill Bit" section too. First, I need advice on models.py models.py from django.db import models # Create your models here. class BHA_overall(models.Model): drill_str_name = models.CharField(max_length=256) depth_in = models.IntegerField() depth_out = models.IntegerField() drilled = models.IntegerField() # ....... class BHA_drill_bit(models.Model): BIT_OPTIONS = ( ('PDC Drag'), ('Roller Cone'), ('other')) color = models.CharField(max_length=256, choices=BIT_OPTIONS, default='other') size = models.CharField(max_length=256) wob_max = models.CharField(max_length=256) # .......

Django: DetailView URL with PK Issue
I'm new to Django and I am trying to build a church directory application to manage users (sheep) in churches (flocks). Everything seems to work until I add a CBV - DetailView for a model named ChurchMembers. I want to use the pk of the ChurchMember to create a DetailView for the member to have a profile.

Django Get Auth User pk to be saved in model after form submission
I am currently implementing Django's Auth Users. I am now attempting to create a form with two simple fields with the User's pk as the foreign key.

One combined model vs Two separated models with similar purpose
In my case, one User can subscribe to another User or Community. And, I can't decide, should a Subscription model be combined for both or should it be separated UserSubscription and CommunitySubscription Combined model will look like that: class Subscription(models.Model): date_subscribed = models.DateTimeField(default=timezone.now) date_unsubscribed = models.DateTimeField(null=True) subscriber = models.ForeignKey(User, related_name='subscriptions') author = models.ForeignKey(User, related_name='subscribers', null=True) community = models.ForeignKey(Community, related_name='subscribers', null=True) is_active = models.BooleanField(default=True) Two separated models will look the same except they'll contain only one of two fields author or community. Not both. The hardest and the most frequent query about Subscription is a subscriber's feed-page which displays Posts based on user`s subscriptions combined: class Post(models.Model): title = models.CharField(max_length=255) text = models.TextField() communities = models.ManyToManyField(Community) # NOTE: THIS IS M2M! author = models.ForeignKey(User) And, I just want to make it right in terms of performance and potential things that I do not see now but can face in future. So, Is there any pros and cons about separated UserSubscription and CommunitySubscription or combined Subscription model? How would you do and why? -

Allowing user to skip multi-factor authentication for 30 days from a device
I've inherited an app at my company (ReactJS/Django), and they've asked me to implement multi-factor authentication. I've got it wired up with django-mfa, and the authentication works great. Now, they've requested that if a user logs in with MFA, they will not be asked for MFA again on THAT device for 30 days. At first, I thought no problem. You can do it with a cookie or whatever as you would any persistent session, and instead of using that to keep the user logged in, you can use it to determine whether or not to ask for MFA verification. The obvious oversight I made in my haste is that theoretically you could have multiple users logged in to that same device. User A could log in with MFA. If you store a cookie with session information that allows User A to skip MFA, what happens when User B logs in? I don't really know any obvious way around this. Is there a straight-forward or conventional way to manage multiple user sessions in a browser, or an alternative approach to this problem I'm missing? -

When making a lesson selection, I would like to make a choice to show which year this lesson belongs to (eg 2011-2012, 2012-2013, 2014-2015). I want it to be automatically calculated instead of writing this selection field by hand. YEAR = ( (2011-2012, _(2011 - 2012)), (2012-2013, _(2012 - 2013)), (2013-2013, _(2013 - 2014)), ) models.py class Lesson(models.Model): department = models.ForeignKey(Department,on_delete=models.CASCADE) academician = models.ManyToManyField(Academician) l_code = models.CharField(verbose_name=_('Ders Kodu'), max_length=7) l_name = models.CharField(verbose_name=_('Ders AdΔ±'), max_length=45) e_year = models.CharField(verbose_name=_('EΔitim YΔ±lΔ±'), max_length=50,) def __str__(self): academician = '-'.join( [str(academician.a_fullname) for academician i self.academician.all()]) return '{department} - {academician} - {l_code}'.format(department=self.department.d_name, academician=academician,l_code=self.l_code) this selection field will be made in admin.py -
