How can i add a footer at the end of the website which is contains for loop in html?
I used : .footer{ position: relative; height: 130px; clear: both; background-color: red; to set a footer at the end of the website but now the footer is not at the end of the all products: html: {% load static %} <!DOCTYPE html> <html> <head> <link rel="stylesheet" href="{% static 'main.css' %}"> </head> <body style="background-color: #36454F;"> {% for i in p%} <div class='card'> <div class="number">{{i.Number}}</div> <img src="{{i.image}}"></img> <p id="id">{{i.description}}</p> <a href="{{i.buy}}" target='_blank' rel='noopener noreferrer'> <button><span class="price"> ${{i.price}}</span> buy</button> </a> </div> {%endfor%} <div class="footer"> <h3>hello</h3> </div> </body> </html> css: .card { max-width: 400px; margin: 0auto; text-align: center; font-family: arial; border-style: solid; border-width: 6px; position: relative; top: 611px; margin-bottom: 33px; margin-right: 33px; justify-content: center; float: left; } .footer{ position: relative; height: 130px; clear: both; background-color: red; } .card img{ height: 400px; width: 400px; vertical-align: middle; } .price {background-color: #f44336; font-size:22px; border-radius: 3px; position: absolute; bottom: 0px; right: 0px; padding: 3px; } .card button { border: none; color: white; background-color: #000; position: relative ; cursor: pointer; width: 100%; height: 100px; font-size: 44px; align-items: center; } .card button:hover { opacity: .5; background-color: #330; } #id{ background-color: palevioletred; color: white; margin: 0; font-size: 17px; } .number{ width: 50px; height: 50px; background-color: #330; color: yellow; border-radius: 50%; position: … -
how to override django/wagtail url path in nginx?
I want to run several wagtail blogs on my server. The code i have is based on a couple of containers for each blog : one nginx container for the frontend and one container for the backend. I would like to serve both containers on one port with the nginx frontend served on / and the backend accessible on /wagtail so i could access to the admin at /wagtail/cms-admin. However when i use this config file for my nginx: server { listen 80; server_name localhost; location / { root /usr/share/nginx/html/storybook-static; index index.html index.htm; try_files $uri $uri/ /index.html; } location /wagtail { proxy_pass http://172.20.128.2:8000;#wagtail server running there proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $host; proxy_redirect off; client_max_body_size 20M; } location /static/ { alias /app/static/; } location /media/ { alias /app/media/; } } the wagtail throws me a msg error "not found". I'm wondering if i dont need to configure something in my wagtail/django files so it recognizes it is served at /wagtail? Any hint on what i'm missing in the configuration? -

React problems with updating state

Django - How to save individual elements of a CharField when a form is submitted?
When I submit my form, I want the text submitted as "note" to be split up, say by paragraph, and also saved to the "tag" part of my model automatically. I have the following as my models.py class NoteModel(models.Model): note = models.CharField( max_length = 5000 ) def __str__(self): return f"{self.note}" class NoteTagModel(models.Model): note = models.ForeignKey( NoteModel, on_delete=models.CASCADE, related_name="notes", blank= False, null = True, ) tag = models.CharField( max_length = 5000 ) def __str__(self): return f"Note: {self.note} | Tag: {self.tag}" I have the following as my forms.py class NoteTagForm(ModelForm): class Meta: model = NoteTagModel fields = [ 'note', ] Is there a way of doing this with Signals? Or would using a hidden inline formset be the best way? Any other suggestions are greatly appreciated. I appreciate that JavaScript may be needed to separate out the text and declare as a variable to be saved as a form value. Many thanks -
djangorestframework-simplejwt with auth0 - settings issue?

Selecting first item in a subquery of many to many relationship in django
Consider having a Book model with many Comments (from different Users) which may belong to many Categories. class Category(Model): title = CharField(max_length=200) class Book(Model): title = CharField(max_length=200) categories = ManyToManyField(Category) class User(Model): name = CharField(max_length=200) class Comment(Book): content = TextField() book = ForeignKey(Book, null=False, on_delete=CASCADE) user = ForeignKey(User, null=False, on_delete=CASCADE) I want to select comments for an specific Book, and for each Comment, annotate it with the number of comments that the writer of that Comment wrote for the first Category of that book. And I want to this in a single query. Something like this: def get_commnets(book): main_category = book.categories.first() n_same_comments_subquery = Subquery( Comments.objects .filter(user__id=OuterRef('user_id'), book__category__first=main_category) .annotate(count=Count('pk')) .values('count') )[:1] comments = ( book.comment_set .annotate(n_same_comments=n_same_comments_subquery) ) return comments The previous piece of code does not work, obviously. This is because there is not any lookup like first. I've tried many other solutions, but non of them worked. How can I achieve this goal? Thank you in advance. -
