Django list view order by alternating supplier
I have a django ListView which queries for products. I now have a new supplier and I get feeds from each supplier at different times of the day. Whenever one supplier updates I get all the updated products from SUPPLIER_A first and then when SUPPLIER_B updates I get all them returning first. This is pushing each supplier off the first few pages so no user will ever see them products for part of the day. How do I alternate by supplier e.g. my products on page 1 will have 12 from each supplier. class Product(models.Model): SUPPLIER_A = "A" SUPPLIER_B = "B" SUPPLIER_CHOICES = ((SUPPLIER_A,SUPPLIER_A), (SUPPLIER_B, SUPPLIER_B)) category = models.ForeignKey(Category, on_delete=models.PROTECT) supplier = models.CharField(choices=SUPPLIER_CHOICES, max_length=20) class ProductListView(ListView): template_name = "product_list.html" paginate_by = 24 def get_queryset(self, *args, **kwargs): slug = self.kwargs.get("slug") return models.Product.objects.filter(category__slug=slug) -
Static File location on Django app deployed to Google App Engine / Cloud SDK
I have developed a website using the latest version of Django, finished all the offline testing, and deployed it to Google App engine. Previously, images and scripts for my website were located in a folder titled ‘scripts’, and running locally I had no problems. Now that my website is deployed however, no images / scripts / static files are successfully loading, and I cannot figure out an appropriate fix. I have successfully created a bucket with google cloud, but I can’t seem to create a functioning path to that bucket. I am unsure whether a html address is a valid parameter for the path location in Settings.py, and regardless replacing the simple HTML address of my google cloud bucket for my STATIC_URL parameter has not fixed the problem. Has anybody else run into this problem, and does anyone know the best configuration for the static_url parameter in Settings.py? Or a simpler way to set up your static files? Thanks in advance! -
How to run same set of test for anonymous user and logged in user?
I have a simple MovieDB app written in Django where webpages differ slightly between logged in view and guest user view. I have a movies list page which doesn't change for logged in user and anonymous user except for sign-in/register links to sign-out. I am currently testing template used, no. of movies listed, movie title, nav-bar links (home, search page, login/register, sign-out, user account). I want to write tests to check these for both type of user only once. -
How to access static file from a template tag in Django to read a text file?
I am building a system where I want to read a text file from my template. This text file is stored in my static folder. In my app_filters, I have the following function: from django import template register = template.Library() @register.filter def print_file_content(file_name): try: file = open(file_name, 'r') return file.read() except IOError: return '' On my template, I am doing this: {% load static %} {% load app_filters %} <div>{{ "{% static 'my_file.txt' %}" | print_file_content }}</div> I have the file in my static folder: myapp/static/my_file.txt, but the file is not read correctly. And the section just remains empty. How can I fix this issue? Thanks for any help. -

Reorganizing ManyToMany models into a different order
I have an setup similar to this. class Author(models.Model): first_name = models.CharField(max_length=30) last_name = models.CharField(max_length=40) books = models.ManyToManyField(Book) def __unicode__(self): return self.title class Book(models.Model): title = models.CharField(max_length=100) author = models.ForeignKey(Author) def __unicode__(self): return self.title Now in my admin panel I can select an author and add Books underneath that specific author. When I print out all the books for each author it prints them in the order that they were added in the admin panel. Is it possible to modify the order in the admin panel so that when they print, they print in the order of the admin panel? -

How to make the images same fit or same size?
I'm developing an e-commerce project in django, I have created a model for images and tried to resize or thumbnail the images but it seems this is not working for my case or maybe this is Front-end issue. When the vendor uploads the image products, I want the image products to fit and look in the same line regardless of the image original size. I don't want them to show like in this picture so I want the price and button to be in the same line. I tried to resize the images but won't work -
Make Django 3 REST render HTML template
I am trying to build a Django (version 3.05) REST API call that will render to a chosen HTML template. I am, however, receiving a number of errors that I haven't found a solution to on StackOverflow (And yes, I've looked far and wide). Since my errors are many and varying depending on what I attempt, let me rather ask how to do it correctly to begin with. In my view set up (below), what do I need to add (or change) in order to render the queryset to an HTML template? models.py: from django.db import models class Hero(models.Model): name = models.CharField(max_length=60) alias = models.CharField(max_length=60) def __str__(self): return self.name serializers.py: from rest_framework import serializers from .models import Hero class HeroSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Hero fields = ('name', 'alias') views.py: from rest_framework import viewsets from .serializers import HeroSerializer from .models import Hero class HeroViewSet(viewsets.ModelViewSet): queryset = Hero.objects.all().order_by('name') serializer_class = HeroSerializer # over here - how do I render the queryset /to/my/template.html myapi/urls.py: from django.urls import include, path from rest_framework import routers from . import views router = routers.DefaultRouter() router.register(r'heroes', views.HeroViewSet) -

Does anyone have an idea how can I set up a specific subscription in stripe with such a special requirements for upgrading and downgrading?
I am working on a platform able to analyse data of the users. I would like to use Stripe payments however I have some problems. At first I would like to describe how I would like my pricing look like in order to make it clearer to understand for you what I want to achieve. During account creation the user can select an amount for example from 1$ to 1000$ that will be available for all services. This amount will be charged every month so this will be working as a subscription plan. The difference is that the amount is not used proportionally each day of the month, as is the case of subscriptions. For example, the user starts one month pricing period 5th of the month with amount equals to 10$. During first 10 days of this period he does not execute any actions so he still has 10$. On the 11th day, he starts the service and uses 4$ within 5 hours. From this time he does not use any tools until the end of the current period and he has 6$ left. I decided at the moment that unused funds will probably not be transferred to the … -

WYSIWYG with images uploader, how to upload images after writing in the wysiwyg
I'm writing an application where a user can write a diary, also the user can add images, so I'm using the input file to choose images and un put inside the content editable. After the images are in the content editable, I can see the html as img base 64. So, I was thinking if is possible to upload images after the user submitted everything? or should I upload the images via Ajax and put inside the editor with the right url. (I only think that this option people can upload images than delete from the editor and these images will be kept inside the server useless.) Thank you for any response! -

Django Bootstrap Modal Forms - Open modal inside another modal
How can I open a model inside another modal in Django Bootstrap Modal Forms? I'm following this guide: https://pypi.org/project/django-bootstrap-modal-forms/#description and I was successful in making a simple modal form. However, I would like to add a new option to the choices in the dropdown list if my choice is not in the list. How can I achieve this output?

How can I use a related field in a SlugRelatedField?
I have the following structures class State(models.Model): label = models.CharField(max_length=128) .... class ReviewState(models.Model): state = models.ForeignKey(State, on_delete=models.CASCADE) ... class MySerializer(serializers.HyperlinkedModelSerializer): state = serializers.SlugRelatedField(queryset=ReviewState.objects.all(), slug_field='state__label', required=False) class Meta: model = MyModel fields = [ 'id', 'state', # this points to a ReviewState object .... ] What I'm trying to do is using the State object's label as the field instead. But it doesn't seem like djangorestframework likes the idea of using __ to lookup slug fields. Would it be possible to do this? If it was: class MySerializer(serializers.HyperlinkedModelSerializer): state = serializers.SlugRelatedField(queryset=State.objects.all(), slug_field='label', required=False) that would be no problem, but I'm trying to use the ReviewState instead. -

Best way to render my python game on a webpage via django
So I just finished making a simple guessing game. You have to guess the random number in 22 guesses. I want to be able to eventually study the data from the users input via machine learning. I decided to use the Django framework. How would I go about doing this? I have set everything up already ( I think ). How do I put the .py game on a webpage. How would I style the logic i made? ( as its just text in a console so far) would i have to put the game in some sort of container and then direct that in a view? I am so confused on the best way to do this lol. Any help will be much appreciated and I am sorry if I am coming across as a noob. :) -
Calling a REST API when a django webserver starts
I have a django webserver that has some code to handle data from dialogflow. So for my project I need to have a user and project list that is cached and will be updated only at regular intervals/ at the startup of webserver. For example Everytime the webserver is started I need to make two rest calls and store the resultant data in variables which i can use later. This is to avoid repeatedly doing those calls since that data is fairly static. Is there a way in django to do this? -

Django page freezes after form submission
