Render different template depending on object class
I have a sorted list with items of three different types. Two are of the same class: q1 = Model1.objects.annotate(created_at=F('created')) q2 = Model2.objects.annotate(created_at=F('creation_datetime')) items = sorted(chain(q1, q2), key=attrgetter('created_at'), reverse=True) Then in the list template: {% for item in items %} ??? {% endfor %} Items of class Model1 should use template1.html, items of Model2 and type X template2X.htmland items of Model2 and type Y template2Y.html. I have thought of the following terrible idea: rendering the template in a tag. @register.assignment_tag(takes_context=True) def render_item(context, item): if isinstance(item, Model1): return render_to_string('template1.html', context) elif isinstance(item, Model2): if item.typeX: return render_to_string('template2X.html', context) elif item.typeY: return render_to_string('template2Y.html', context) return render_to_strong('unknown.html', context) And then: {% for item in items %} {% render_item item as html %} {{ html }} {% endfor %} What's the appropriate way to do this? -

Django - how to do an aggregation inside annotation
My models are the following: class Content(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, null=True) second_contents = models.ManyToManyField('self', related_name='first_contents', blank=True) class Fight(models.Model): win_content = models.ForeignKey(Content, db_index=True, on_delete=models.SET_NULL, related_name="wins", null=True) loss_content = models.ForeignKey(Content, db_index=True, on_delete=models.SET_NULL, related_name="losses", null=True) user = models.ForeignKey(User, db_index=True, related_name="clashes", on_delete=models.SET_NULL, blank=True, null=True) timestamp = models.DateTimeField(auto_now_add=True) class Hashtag(models.Model): hashtag = models.CharField(db_index=True, max_length=50, null=False, unique=True) contents = models.ManyToManyField(Content, db_index=True, related_name="hashtags", blank=True) Each Content in Content.second_contents builds a Pair of two contents. Each Content can have n second_contents One Pair Result is defined as one Fight object containing both Pair Content objects as win_content and loss_content. Now let's say I have a Hashtag object with 10000 Content objects as Hashtag.contents. I want to get the top100 Pair of Contents which have the most Results, so in the end I'm looking the get some order_by Queryset with an annotated item count. What I've tried: contents = (Content.objects .filter(hashtags__in=hashtagid) .filter(first_contents__in=contents) .annotate( count="""some query like max(count(wins, filter=Q(second_contents__in=F('content'))) + count(losses, filter=Q(second_contents__in=F('content'))))""" ) .order_by('count')[:100] ) Is there any way to perform that query as an annotation? e.g. loop through each Content.second_contents relationship, count the number of wins and losses, and finally annotate the Max value? I'm kind of stuck with my current knowledge of possible queries and can't see … -
Django - Form template throws "This field is required" for Imagefield
I'm having some trouble with image upload in Django 3.0. I'm experiencing the issue where trying to upload an image from my template throws the error "This field is required" even though i have a file selected. It uploads fine I do it from the form in the admin area. models.py class Image(models.Model): title = models.CharField(max_length=50) image = models.ImageField(upload_to='images/') def __str__(self): return self.title views.py def new_post_view(request): new_img = ImageForm(request.POST or None) if new_img.is_valid(): new_img.save() new_img = ImageForm() return redirect('imageposts:gallery') return render(request, 'imageposts/create.html', {'new_pic': new_img}) forms.py class ImageForm(forms.ModelForm): class Meta: model = Image fields = [ "title", "image", ] widgets = { "title": forms.TextInput(), "image": forms.FileInput(), } create.html {% extends 'base.html' %} {% block content %} <form method="post" enctype="multipart/form-data"> {% csrf_token %} {{new_pic.as_p}} <button type="submit">Add image</button> </form> {% endblock %} Solutions i've seen have been to make the field nullable and empty, but for this case, the image is an always required, but it's just not uploading the selected file. The form just clears the file section and throws "This field is required." I've tried in both django 3.0 and django 2.2 and I get the same result.

Filter a queryset by a list of users and request.user at the same time
I would like to create a queryset containing posts from both a list of 'friends' and 'request.user'. So far I can only filter posts by friends using posts = Post.objects.filter(user__in=friends). I tried to do posts = Post.objects.filter(user__in=friends).filter(user=request.user) but this returns an empty queryset. I can't figure out how to filter 'posts' using both parameters at the same time. Any suggestions would be much appreciated, cheers. -

putting a pandas dataframe inside a django template
I want to put a pandas dataframe inside a django template. For instance I want something like this: <html> <head><title>HTML Pandas Dataframe with CSS</title></head> <body> THE PANDAS DATAFRAME </body> </html> What I have tried are these codes. First in my django views.py, this was my function: from django.shortcuts import render import pandas as pd def about(request): df = pd.DataFrame({'a': [12, 3, 4], 'b': [5, 6, 7]}) df = df.to_html(classes='mystyle') return render(request, 'blog/about.html', {'table': df}) The template is: {% load static %} <link rel="stylesheet" type="text/css" href="{% static 'blog/style.css' %}"> <html> <head><title>HTML Pandas Dataframe with CSS</title></head> <body> {{table}} </body> </html> And, the style.css is: body { background: black; color: white; } Apparently, when I check it in my browser the template is loaded with the CSS code correctly but it gives me the following output instead of the table that I want: <table border="1" class="dataframe mystyle"> <thead> <tr style="text-align: right;"> <th></th> <th>a</th> <th>b</th> </tr> </thead> <tbody> <tr> <th>0</th> <td>12</td> <td>5</td> </tr> <tr> <th>1</th> <td>3</td> <td>6</td> </tr> <tr> <th>2</th> <td>4</td> <td>7</td> </tr> </tbody> </table> I am new to django, so maybe my approach is completely wrong. -
When a superuser logs in, check if a model object exists, if not, redirect to creation
Consider a model called AppSettings. Let's say the project has recently been installed on a server and I want to make it so that whenever a superuser logs in, before adding any other model objects or doing anything else, I want to first check if there's an AppSettings object. If there isn't I want to immediately redirect to the AppSettings add form and allow actions after there's at least one object. There would be a auto_add datetime field called "last_update" so we can check for the last object by doing AppSettings.objects.latest("last_update"). I just want to know how to check and redirect and where to put that code or any other way to achieve my goal. Thank you for your time, I appreciate it. -

manipulation the original source of a file or video url like youtube player or cloud file download sites
