Filtering with multi field in django orm
I have some fields that I can use them for filtering a list. I can use all of this fields or some of them in filter query. MY view is like below. But I can not get a right answer.

Form errors not displaying in UpdateView
I have an UpdateView that will display a form to either create the user profile or update the user profile. It works well, however, for some reason I can't get it to show the form errors. There should be form errors based on the ValidationErrors I have put in the model form. I suspect my views.py to be the cause of the form not displaying the errors. Here's my view: class ProfileSettings(UpdateView): model = Profile template_name = 'profile/settings.html' form_class = ProfileForm success_url = reverse_lazy('profile:settings') def post(self, request, *args, **kwargs): form = self.form_class(request.POST, request.FILES) if form.is_valid(): bio = form.cleaned_data['bio'] gender = form.cleaned_data['gender'] avatar = form.cleaned_data['avatar'] Profile.objects.update_or_create(user=self.request.user, defaults={'avatar':avatar, 'bio':bio, 'gender':gender}) return HttpResponseRedirect(self.success_url) -
How to pass an instance ID to an Update view when using Bootstrap Modal in Django?
I started learning Django around 7 months ago and earlier this week I got called in for an internship interview for a software development company and I have to go in and present a challenge on Monday. I have to build a phone catalog website with a basic CRUD and a few other options. Basically just implement a table that displays name, email and phone number, with options to add, remove and update contacts. On my own I decided I wanted to use Bootstrap Modals to handle the add and update templates. This is my Model: class Contacts(models.Model): id = models.AutoField(primary_key=True, unique=True, null=False) name = models.CharField(max_length=100, null=False) address= models.CharField(max_length=150, null=False) phone = models.CharField(max_length=14, null=False) email = models.CharField(max_length=100, null=False) gender = models.CharField(max_length=1, null=False) birth = models.CharField(max_length=10, null=False) And this is my home view: def home(request): #create form form = now_contact_form(request.POST or None) contacts = Contact.objects.all() #edit form edit_form = edit_contact_form(request.POST or None, instance=Contacts) #dictionary data = {'form': form, 'contacts': contacts, 'edit_form': edit_form, } #save if form.is_valid(): contato = form.save(commit=False) contato.save() return redirect('index') if editar_form.is_valid(): editar = editar_form.save(commit=False) editar.save() return redirect('index') return render(request, 'index.html', dados) When I try to run like this, this is what I get. Now, I know the problem … -

Django/PayPal : How can i retrieve Data from PayPal checkout.js?

How to create nested serializer for extended User module with user_id as foreign key
I'm using django-rest-framework and working on application where I have default User module, then UserProfile to extend it and trying to implement "Favorites" feature and for that reason I added additional table Favorites. So there is my UserProfile module: class UserProfile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) ... and there is my Favorite module: class Favorite(models.Model): user = models.ForeignKey(User, related_name='user_favorite', on_delete=models.CASCADE) song = models.ForeignKey('Song', related_name='song_favorite', on_delete=models.CASCADE) I plan to add another field to favorites for movies. There is my Serializers: class FavoriteSerializer(serializers.ModelSerializer): class Meta: model = Favorite fields = [ 'user', 'song' ] class UserSerializer(serializers.ModelSerializer): class Meta: model = User fields = ( "id", "email", "first_name", "last_name", "username", "is_active" ) class UserAuthSerializer(serializers.ModelSerializer): user = UserSerializer(required=True) favorite = FavoriteSerializer(many=True, read_only=True) class Meta: model = UserAuth fields = '__all__' ... I also have some create function in UserAuthSerializer but I don't think that it is relevant in this case. I've tried to put this part favorite = FavoriteSerializer(many=True, read_only=True) into UserSerializer but result is the same. So as you can see I added favorite into UserAuthSerializer and fields should display all fields, but I don't have favorite in my response! There is no error, but it just missing this field my view for this … -
Generate jwt when registering user using djangorestfrfamework-simplejwt
Hi i'm playing with django and djangorestframework-simplejwt and wrote a simple app to register users. Now it seems from reading the documentation and searching online the only way of generating a token is by passing the username, and password to the url url(r'^api/token/$', TokenObtainPairView.as_view(), name='token_obtain_pair'). So it seems i have to create the user first and upon successfully creating the user then send the username, and password again to the url to generate a token. But i want to be able to create a token when the user is created and not have to resend the username and password after user is created. Is there an easier away to generate a jwt when registering a user. -

Firefox SPNEGO Negotiate protocol - multiple connections?
I'm using gssapi/Kerberos authentication in my web application, and I want single sign on via the browser. The problem is, Firefox sends an initial request to the server with no authentication, and receives a 401. But it includes a keep-alive header: Connection: keep-alive If the server respects this keep-alive request, and returns a WWW-Authenticate header, then Firefox behaves correctly and sends the local user's Kerberos credentials, and all is well. But, if the server doesn't keep the connection alive, Firefox will not send another request with the credentials, even though the response has the WWW-Authenticate header. This is a problem because I'm using Django, and Django doesn't support the keep-alive protocol. Is there a way to make Firefox negotiate without the keep-alive? In the RFC that defines the Negotiate extension, there's nothing about requiring that the same connection be re-used. Alternatively, is there a way to make Firefofx preemptively send the credentials on the first request? This is explicitly allowed in the RFC. -

Django annotate with multiple tables
Given the models: class Member(models.Model): first_name = models.CharField(max_length=200) last_name = models.CharField(max_length=200) class MemberAction(models.Model): member = models.ForeignKey(Member, on_delete=models.CASCADE) action = models.CharField(max_length=200) datetime = models.DateTimeField() points = models.IntegerField() class MemberMention(models.Model): member = models.ForeignKey(Member, on_delete=models.CASCADE) date = models.DateTimeField() points = models.IntegerField() I want to get the top five Members with the most combined MemberAction and MemberMention points for a given week. I also want the query to return all of a member's MemberAction rows for the given dates. Any idea how to do this? I got as far as the code below, but the number returned for points_action is incorrect. Oddly enough, when I remove the annotate call for points_news, it works correctly. def index(request): today = timezone.now() week_ago = today - timedelta(7) ma_w_dates = MemberAction.objects.filter(datetime__date__gte=week_ago,datetime__date__lte=today) mention_pts = Sum('membermention__points', filter=Q(membermention__date__date__gte=week_ago,membermention__date__date__lte=today)) action_pts = Sum('memberaction__points', filter=Q(memberaction__datetime__date__gte=week_ago,memberaction__datetime__date__lte=today)) members = Member.objects.annotate(points_actions=action_pts).annotate(points_news=mention_pts).order_by('-points_actions').prefetch_related(Prefetch('memberaction_set', queryset=ma_w_dates))[:5] context = {'members':members} return render(request, 'data/index__text.html', context) -
Migrate a PositiveIntegerField to a FloatField
I have an existing populated database and would like to convert a PositiveIntegerField into a FloatField. I am considering simply doing a migration: migrations.AlterField( model_name='mymodel', name='field_to_convert', field=models.FloatField( blank=True, help_text='my helpful text', null=True), ), Will this require a full rewrite of the database column? How well might this conversion scale for larger databases? In what circumstances would this conversion fail? -

I am having trouble linking Css File to Django Template
I just started learning django framework and i tried to add and use static files to design a template(to change the background) of webpage with simple css but my css file doesn't seem to link with html template as the background did not change. I looked up various solutions and it doesn't seem i am doing anything wrong in the code but it still doesn't work. Please look at the code, what could i be missing? Here is the code for the template; {% load staticfiles %} <link rel="stylesheet" type="text/css" href="music/style.css"> {% if all_albums %} <h3>My Albums</h3> <ul> {% for album in all_albums %} <li><a href="{% url 'music:detail' album.id %}">{{album.album_title}}</a></li> {% endfor %} </ul> {% else %} <h3>You don't have any albums</h3> {% endif %} Here is the css; body{ background: white url("images/blackbackground.jpg"); } I expected the background to change but it didn't. The server returned error message "Not Found: /music/music/style.css [01/Feb/2019 12:15:26] "GET /music/music/style.css HTTP/1.1" 404 2559" guys what am i missing? -
