Django: Ordering Objects Manually w/ A Field
I have a django model with an index IntegerField. I want to allow users to manually order these objects via a drag and drop interface. The idea is to update the ordering by updating this index field when one of the objects is dragged to a new position. So, for example if a user drags the 4th item to the top, that object will then be index 0, former index 0 will be index 1, former index 1 will be shifted to index 2 and so on. Is there a good way to do this in a single Django ORM call, without needing to iterate through the entire list of objects and increment the index? Say I want to insert an object that was at Index 4 at Index 2– is there a way to shift all indexes >= 2 by +1? -

Django AllAuth - Link UserProfile stored in session to User created from Google Signup
I want to allow users to sample my Django website before prompting them to sign up with Google (which I implement using the django-allauth package). I want them to be able to create a UserProfile with their name, age, preferences, etc. and allow them access to the site. class UserProfile(models.Model): user = models.OneToOneField(User, null=True, blank=True, on_delete=models.CASCADE) name = models.CharField(max_length=25, null=True, blank=True) age = models.IntegerField(null=True, blank=True) I do this by creating a UserProfile with no associated User, and storing their UserProfile pk in the session as follows: userprofile = UserProfile(name='Harry', age=28) userprofile.save() request.session['userprofile_pk'] = userprofile.pk Then when the user eventually decides to sign up via Google, I'd like to link their UserProfile to the User model like so: userprofile_pk = request.session.get('userprofile_pk') userprofile = UserProfile.objects.filter(pk=userprofile_pk).first() userprofile.user = request.user # User that has just been created using the django-allauth Google package userprofile.save() The problem I'm facing is that the django-allauth package creates the User, logs them in, and redirects to the url specified in my LOGIN_REDIRECT_URL, which clears the session and all access to the userprofile_pk. Is there a way I can link the UserProfile stored in the session to the newly created User? -
Is there anyway to run a game irrespective of reloding page in django
I need a way to run this number game irrespective of request. It should accept the forms submitted from this same page. I found that js clock and backend clock are not synchronized so I have started reloading this game tab for each second. So that time modules are creating newly after every refresh. And another problem is when a new user visits this page it will create time modules newly which ruin this game. So please suggest me a better way to do this. views.py class NumberSection(ListView): template_name = "gamepage.html" def get(self, *args, **kwargs): context = {} silver_created=False if not silver_created: silver_end,silver_gold_buffer,silver_gold_new,silver_gold_correct,silver_gold_start = create_time_modules() self.silver = True silver_game = NumbersGame.objects.create(mode='silver') self.silver_game_id = silver_game.id context['silver_status'] = 'accepted' silver_created =True if silver_created: if silver_end<=datetime.now(): self.silver = False context['silver_status'] = 'blocked' if silver_gold_buffer<=datetime.now(): pass if silver_gold_new<=datetime.now(): silver_created = False while True: silver_x = silver_gold_correct - silver_gold_start context["silver_minutes"]=(silver_x.seconds//60)%60 context["silver_seconds"]=silver_x.seconds%60 return render(self.request,self.template_name,context=context) def post(self, *Args, **kwargs): name = self.request.POST.get("choosen") amt = self.request.POST.get("total") if name == 'silver' and self.silver: hist = History.objects.create(user=self.request.self.user.userprofile,investment=amt,color_num_selected=name) hist.id_made = self.silver_game_id hist.save() return redirect('core:next') -

Why I can't display data of a user in Django?

Return a template after fetch
I made a fetch POST with data I want to handle on my server. I want to get that Json values sent by the fetch and use them to return a template, so i'm doing: def prepricing(request): if request.method == "POST": content = json.loads(request.body) return render(request, "letter/pricing.html", { "mail":content['mail'], "name":content['name'], "content2":content['content'] }) The post method is triggered.

Any ideas? -

Django: child drop down value is not returning, from dependent drop down set
I have a dependent drop down set for Makes and Models. Javascript is used to detect the change on the Make and then to filter/populate the Model dropdown from a Model. This appears to work well. I need the child drop down value to then perform a search of inventory on another html page, which I'm creating through a view. I instead of passing the child value, the parent value is always returned. This means I can generate a search/filter using the make but not the model as is required. I have tried many combinations of requests and changing the drop downs as well as an attempt at hidden variables to obtain the java script variable in place of pulling back the dropdown option via the name attribute ..... so far no success. Really need some guidance here.

How to make a like button with jquery inside a form so that it will save it to database and also change the style of like button?
I am working on a django project and I want to add a like button to the posts. this is my template: <form action="{% url 'like' post.id %}" method="GET" name="liked" class="l-form"> {% csrf_token %} <button style="display: inline;" class="like__btn"> <i class="like__icon fa fa-heart" style="display: inline;"></i> </button> </form> <script> $('.like__btn').on('click', function(){ $('.like__icon.fa-heart.fa').toggleClass("liked"); }); </script> All I want to do this, when user clicks on a heart icon, it will submit the form. But also change the icon color to red. (liked class is basically, color:red) When I click on the button it submits the form, increases the like count, but then it refreshes the page so my heart icon doesn't stay red. If I add type="button" this time it doesn't refresh the page, change the color of the icon but doesn't submit the form. I tried to do another button to submit the form and make it hidden but whenever the form is submitted it refreshes the page and goes back to the white heart. Also tried to return false; in jquery but it doesn't submit the form again. I am stuck for hours, so any advice would be great! -
Should race conditions be handled in form or view?
Lets suppose I have to withdraw money from a specific wallet object. So I first check if x amount of money is in wallet.. Then I lock wallet object in form clean() method, then check it. If the wallet has enough money, form is valid and we proceed to the view. In the view the withdraw action happens but in the view, the wallet object won't be locked anymore.. If two threads manage to reach to the view at the same time, race condition may occur. should the transfer action happen in the clean() form method where the wallet object will be locked or validate the amount of money of the wallet in the view? -

Why is the Django Admin bad for multiple users
I'm trying to find out why Django Admin is bad to use for users around > 10000 users and why people insists that I should serialize with for example Django REST API and use JavaScript on frontend to handle the data.

Is it possible to create an alias for deep joins/relationships?
I am adding some functionality to an app where a user can sort records in a table on the frontend (react) by passing additional url parameters to the backend. We use this in several places, and have a Mixin for pagination. In the pagination mixin I have the following: def get_queryset(self): order_by_field = self.request.GET.getlist("order_by") if order_by_field: return super().get_queryset().order_by(*order_by_field) else: return super().get_queryset() This works great, I can pass urls like {app_base_path}/{some_resource}/?order_by=title to get it to sort the returned query set by the queried model's title field. It also works with multi-sort (e.g. {app_base_path}/{some_resource}/?order_by=title&order_by=date). However, this looks very ugly and reveals unneccessary information to the end user for deeply nested relationships. For instance if I want to sort by a related field through an intermediary table: {app_base_path}/{some_resource}/?order_by=intermediary_model__related_model__field_of_interest. Is there a way I can make this nested relationship an alias on the model I am querying? Something like: class MyModel(models.model): # other model fields, etc. @property def alias(): return "intermediary_model__related_model__field_of_interest" -
