counting distinct values within a distinct value search on another field within same jango model
I am trying to pull some analytics from my django model table. So far I can count total values of a field and distinct values of a field. I also know how to create lists showing total values of fields within a distinct field. Now i'd like to count the distinct instances a field occurs within a list of already distinct values of a different field. Here's the table I am working with: | uid | cid | |-------|--------| | a | apple | | a | apple | | a | grape | | b | apple | | b | grape | | c | apple | | c | pear | | c | pear | | c | pear | So the result I am trying to provide is: cid: apple (distinct uid count: 3), cid: grape (distinct uid count: 2), cid: pear (distinct uid count: 1) and also: cid apple's distinct uid's: a, b, c cid grape's distinct uid's: a, b cid pear's distinct uid's: c So far I have been able to get distinct counts and lists like this: dist_uid_list = Fruit.objects.filter(client=user).values('uid').distinct() output >>> {'uid': 'a', 'uid': 'b', 'uid': 'c'} and this: dist_uid_count = … -

Python Django uses wrong query

Msgid in django not being recognized when it starts with percent symbol
Any msgid's that are created for translation do not seem to be recognized if it starts with %. The msgid and msgstr are created in the django.po file but when the code is run, the message remains untranslated. I am wondering if python-format is trying to recognize the % symbol as a placeholder, but I tried to escape the symbol and that still was not the solution. I am wondering if there is something else I am missing. -
How can I connect multiple models in Django
I`m a beginner in Django and want to create a system in the Django-models were a user can upload a course with a title and different Chapters which all can have multiple videos in them. As seen in this image. I thought about creating three models 1. Course with the course title 2. Chapter which has different videos in them 3. Video And here the video with a title of the video But I have no Idea how to create a connection between those three models, so that there can be multiple chapters in one course and multiple videos in one chapter. These are my first models (I just created them quickly): def user_directory_path(instance, filename): # file will be uploaded to MEDIA_ROOT/user_<id>/<filename> return 'user_{0}/{1}'.format(instance.user.id, filename) class video(models.Model): title = models.CharField(max_length=100) video = models.FileField(upload_to=user_directory_path) class course(models.Model): title = models.CharField(max_length=100) class chapter(models.Model): pass How should I adjust the models and create the connection to accomplish the system that I´m after? -
How to add labels for Django models.IntegerChoices
I have two IntegerChoices subclasses in one of my django Models that define ticket priorities for an api. I would like when the priority and statuses are rendered on my web page to show the label, but then when using the api to send the integer number corresponding with the label. This is my code so far: class Ticket(models.Model): class Statuses(models.IntegerChoices): OPEN = 2, 'Open' PENDING = 3, 'Pending' RESOLVED = 4, 'Resolved' CLOSED = 5, 'Closed' class Priorities(models.IntegerChoices): LOW = 1, 'Low' MEDIUM = 2, 'Medium' HIGH = 3, 'High' URGENT = 4, 'Urgent' priority = models.IntegerField(default=Priorities.LOW, choices = Priorities.choices) status = models.IntegerField(default=Statuses.OPEN, choices=Statuses.choices) I then try to access the label in my application via <b>Priority: </b> {{ ticket.priority.label }} <br> <b>Status:</b> {{ ticket.status.label }} But nothing shows up. It seems the Django docs for the new IntegerChoices class is very minimal, and is not clear about how the labeling function works. I also tried rendering the labels like so: OPEN = 2, _('Open') But then I got an error saying "name '_' is undefined" Any pointers in the right direction for what I need to do? -

Django local memory caching not working on heroku

Method on django model to return the count of a foreign key
I want a method on a django model that returns the count of members in a foreignkey. I'd prefer it to be a class method (and not annotation) because I want to serialize it and send it via javascript without involving templates. Based on previous answers to similar questions, I believed the following sort of structure would work (some attributes deleted for the sake of simplicity): class Post(models.Model): likedby = models.ForeignKey('User', on_delete=models.CASCADE, null=True, blank=True, related_name='liked') def likes(self): return self.likedby_set.count() But when I run this I get AttributeError: 'Post' object has no attribute 'likedby_set'. Anyone know why this doesn't work? -

Django adding CSS classes to field
I am trying to add an error class to fields of a each form in a formset if a custom clean method detects errors. This does look to do the trick, I load the page, and the field does have the error class in it. but when in the template I add a custom filter to add a form-control class, everything falls apart. # in my inlineformset: def clean(self, *args, **kwargs): if any(self.errors): errors = self.errors return ## 1) Total amount total_amount = 0 for form in self.forms: if self.can_delete and self._should_delete_form(form): continue amount = form.cleaned_data.get('amount') total_amount += amount if total_amount> 100: for form in self.forms: form.fields['amount'].widget.attrs.update({'class': 'error special'}) raise ValidationError(_('Total amount cannot exceed 100%')) And, here is my code for the custom filter: @register.filter(name = 'add_class') def add_class(the_field, class_name): ''' Adds class_name to the string of space-separated CSS classes for this field''' initial_class_names = the_field.css_classes() ## This returns empty string, but it should return 'error special' class_names = initial_class_names + ' ' + class_name if initial_class_names else class_name return the_field.as_widget(attrs = {'class': class_names,}) And, in my template: {# {{ the_field|add_class:"form-control"}} #} #<- This adds the form-control, but removes the other classes added in the clean method {{ the_field }} … -
Django: How can I set form instance as a variable which was defined inside the HTML page?
So my blog has posts and comments. I want the users to be able to edit the comment through a BOOTSTRAP MODAL that opens inside the same page when you click the edit button. But I'm actually facing a problem, now there is a for loop inside the html page where I defined the comment variable : {%for comment in comments%} <button type="button" class="btn btn-warning btn-sm" data-toggle="modal" data- target="#Edit{{comment.id}}Modal">edit test</button> {%endfor%} Code at Views.py : post = Post.objects.get(slug=slug) comments = post.comment_set.all() if request.method == 'POST': editcommentform = CommentForm(request.POST, instance=comment) if editcommentform.is_valid(): editcommentform.save() else: editcommentform = CommentForm(instance=comment) now in my views.py I cannot actually set the instance to comment because I get an error of "comment is not defined" My question is how can i set the instance to comment while it's only defined inside the for loop in the HTML page? Sorry if it may sound unclear or weird, I am new to the field. -
Sending websockets message from inside of Consumer's connect() closes the connection
While tracking down the root cause for this question I stumpled upon an issue with using self.send() from inside the connect() of a AsyncWebsocketConsumer. It closes the websocket instead of sending the message: import json from uuid import UUID from channels.generic.websocket import AsyncWebsocketConsumer from myapp.models import AnalysisResult class AnalysisConsumer(AsyncWebsocketConsumer): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.analysis_id = self.scope['url_route']['kwargs']['analysis_id'] self.analysis_group_name = "analysis_{}".format(self.analysis_id) async def connect(self): await self.channel_layer.group_add(self.analysis_group_name, self.channel_name) # Setting up this whole channel / websocket connection takes a while. Thus, we need # to send an initial update to the client to make sure a (too) fast analysis result # doesn't get lost while we've been busy here. # Problem: This is DISCONNECTING instead of sending the message. await self.send(text_data=json.dumps({ 'progress_percent': 100, 'status_text': "Done already." })) await self.accept() async def disconnect(self, code): await self.channel_layer.group_discard(self.analysis_group_name, self.channel_name) Is that expected behavior and I shouldn't try to send something via the websocket from inside the Consumer's connect() method? Or should that be working? -
