Page not found (404) No MenuCategories matches the given query
I created a Django application, the essence is this: data is added through the admin panel, which is then displayed on the main page. I added the data, but they are not displayed on the page; instead an error is displayed: Page not found (404). No MenuCategories match the given query. How can this be fixed? Here is my code in models.py: from django.db import models class MenuCategories(models.Model): name = models.CharField(max_length=50) parent = models.ForeignKey('self', on_delete=models.CASCADE, blank=True, null=True) explicit_url = models.CharField(max_length=100, blank=True, null=True, unique=True) def __str__(self): return self.name def children(self): return self.menucategories_set.all() def get_elder_ids(self): if self.parent: return self.parent.get_elder_ids() + [self.parent.id] else: return [] -

Django: How to populate model field value using another field in django model?
I want to auto-populate a Model field with data from another field, according to the value of that field, i will then auto add a new value the empty field. class Predictions(models.Model): amount = models.DecimalField(max_digits=999999999, decimal_places=2, default=0.00) current_amount = models.DecimalField(max_digits=999999999, decimal_places=2, default=0.00) def save(self, *args, **kwargs): if self.amount: self.current_amount = self.current_amount super(Predictions, self).save(*args, **kwargs) As you can see i have overridden the save method and assigned the value of current_amount to amount, Now the problem is this, when a user want to update this model, i don't want the current_amount to still be set to the amount, some calculation would be done on the curren_amount, so i want the new values for current_amount to remain. So I thought of doing this in the create view and not override the save method This is what i came up with NOTE: I am peforming some other operations in the code, so it might be a little long (the code). class ProductInline(): form_class = PredictionForm model = Predictions template_name = "core/create/create_bet.html" def form_valid(self, form): named_formsets = self.get_named_formsets() if not all((x.is_valid() for x in named_formsets.values())): return self.render_to_response(self.get_context_data(form=form)) # self.object = form.save() # new_form = form.save(commit=False) # new_form.user = self.request.user # self.object = new_form.save() self.object … -

DJANGO RF - Include the SerializerMethodField when nesting a serializer in another serializer
I have a serializer on my UserProfile model. It includes a SerializerMethodField "userGlobalPoints" : class UserProfileSerializer(serializers.ModelSerializer): userGlobalPoints = serializers.SerializerMethodField() def get_userGlobalPoints(self, obj): (*** calculation ***) return userGlobalPoints class Meta: model = UserProfile fields = '__all__' In my Post serializer, I want to nest, for each post, informations about the post's author. So I include fields from the UserProfile model (there is a ForeignKey relation in the Post model). I would like to add the userGlobalPoints field. But I can't figure out how I can nest this field in the serializer. It looks like the usual syntax for nesting a serializer does not work on SerializerMethodField fields. This is my PostSerializer: class PostSerializer(serializers.ModelSerializer): pk = serializers.ReadOnlyField() authorNickname = serializers.CharField(source='postAuthor.userNickname', read_only=True) authorProfileWithGlobalPoints = UserProfileSerializer(many=False, read_only=True) class Meta: model = Post fields = ['pk','authorNickname','postText', 'postTimestamp', 'authorProfileWithGlobalPoints'] Any help on how to achieve this would be apreciated! -

Django Models to Client
So I'm a kid trying Django for the first time, and I'm trying to convert one of my old Python games (a board game called Ludo) into the client side of this. For this, I need to call every instance of the model Goti (defined in the models.py part of Django). I need to do this in the template.html file. How should I do that? For reference, it would be calling all instances of Goti, and pushing it into a list called gotis[] so that I don't have to keep calling every instance. As I said earlier, how do I do that? -

Need Advice in Javascript - New font family for every div
I'm making a post site, but I'm trying to make each post have it's own individual font family. You can see here with the cursive font, it is assigning it properly, but to all of a class.

How to change add and remove tags with JS in django template
I have a quiz Django app which consists of two parts. One is showing 10 sentences with their audio to remember, one per page, and the second is asking questions for the same set of sentences. First part was set up with js function which creates pagination in my html the following way: <button id="prev">prev</button> <button id="next">next</button> <script> var my_objects = `{{ my_objects|safe}}:` #list of items from my view function function paginate(action) { console.log(action) if (action ==='next') { page_number++; } else{ page_number--; } audio.src = `path/to/audio`; $('#dd').empty(); $('#dd').append('<li><h1>'+ my_objects[page_number].fields['content'] +'</h1></li>'); $('#dd').append(audio); $('#dd').append(translation); $('#page_number').val(page_number); } document.addEventListener('DOMContentLoaded', function() { document.querySelector('#next').onclick = function() { paginate('next'); #same goes for 'prev' button. } }) </script> Now when the user paginated through all the sentences I want to show the continue button and if the user clicks it, start the second part. The second part has absolutely same page except I need to hide content of my objects and leave only audio or vise versa and add textarea tag for the user's input. After that I need to loop over my objects again - now in the form of questions. I need to do that without page re-rendering. I tried to make it with tag disabling … -
How to get only the most recent post from each user, ordered by created date
I'm trying to create a social media site in Django where the homepage will display a list of each friend's most recent post, with the newest at the top. At the moment I'm ignoring the friendship functionality and just displaying posts from all users. My current code gets the most recent post from users, but doesn't then order that list by created date. views.py: class PostList(generic.ListView): model = Post # Gets the most recent post from each user # However, the returned set is not ordered by created_on queryset = Post.objects.order_by('author', '-created_on').distinct('author') template_name = 'home.html' I can't change the order_by call as it throws this error: SELECT DISTINCT ON expressions must match initial ORDER BY expressions I know it's possible because I did it ~5 years ago but I don't know what approach I took then and the code is lost. -
Which is better way to rotate logs of Django Application, logging Module of Python or Logrotate of linux?
I want to rotate my logs of Django application, I am able to rotate the logs (based on size) successfully with logging module of python but its causing issue because same log file is getting accessed by celery process and other processes and because of that sometimes application is writing logs in debug.log.1 instead of debug.log file (assume my log file name is debug.log). I suspect this is because my celery process and django server (uwsgi server) is running by different user and because of permission issue it is behaving like that. I am thinking of using logrotate of linux to rotate my log instead of using python class logging.handlers.RotatingFileHandler Can anyone help me in choosing the best way to rotate the log also if you can help me understand why my application is suddenly writing logs in debug.log.1 file instead of debug.log that would be great. -
why i get this Error: missing 1 required positional argument: 'request'
urls.py path("approve_questions/", Approve_questions.posst, name="muster"), # i wann call this function(Approve_questions.posst) in a class path("approve_questions/", Approve_questions.as_view(), name="approve_questions"), class Approve_questions(ListView): form = QuesModel.objects.filter(flaag__exact="False") def get(self, request, *args, **kwargs): form = self.form context = {"form": form} return render(request, "approve_question.html", context) def posst(self, request): return print("anim") how i call about urls.py a function in a class. In this case i wanna call posst but i get the Error: Approve_questions.posst() missing 1 required positional argument: 'request' How i can fix that? Thank you Guys!!!
