How I can store images in Database by using url to images
My problem is that I want to store images in database, but I don't want to store them physically in my project as static files, I want to save in database url to images which are already uploaded somewhere in Internet. How can I do this, just use CharField or TextField as type of field and paste url? But I also want later to display this photo in my template. class Image(models.Model): name = models.CharField(max_length=25, verbose_name='Image name') image_file = def __str__(self): return self.name -

Can't dynamically create path with upload_to
In my user model, I have an ImageField that contains an upload_to attribute that will create the image path dynamically based on the user's id. avatar = models.ImageField(storage=OverwriteStorage(), upload_to=create_user_image_path) def create_user_image_path(instance, image_name): image_name = str(instance.user.id) + image_name[-4:] return 'users/{0}/avatars/{1}'.format(instance.user.id, image_name) When I sign up, I get an error that looks like this: The system cannot find the path specified: 'C:\Users\xx\PycharmProjects\project_name\media\users\150\avatars' If I remove the id and avatars and just include the image name (with no new directories) it works successfully and writes the image. I have tried doing chmod -R 777 on this directory, but it still doesn't create these new directories dynamically. I'm not sure what I'm doing wrong. -

Validate two inline models in the Django admin
I have three models that look like this (simplified from the actual models): class LayoutPage(models.Model): name = models.CharField(max_length=190, unique=True) height = models.DecimalField(max_digits=10, decimal_places=4) width = models.DecimalField(max_digits=10, decimal_places=4) class PageImage(models.Model): page = models.ForeignKey(LayoutPage) name = models.CharField(max_length=150) class Meta: unique_together = ('page', 'name') class PageText(models.Model): page = models.ForeignKey(LayoutPage) name = models.CharField(max_length=150) class Meta: unique_together = ('page', 'name') My admin definitions look like this: class PageImageInline(admin.TabularInline): model = PageImage form = PageImageForm class PageTextInline(admin.TabularInline): model = PageText form = PageTextForm class LayoutPageAdmin(admin.ModelAdmin): inlines = [LayoutImageInline, LayoutTextInline] And my forms look like this: class PageImageForm(forms.ModelForm): def clean(self): cleaned_data = super(PageImageForm, self).clean() page = cleaned_data.get('page') name = cleaned_data.get('name') if page.pagetext_set.filter(name=name).exists(): self.add_error('name', forms.ValidationError(_('Cannot be the same name as an existing layout text on the page'), code='name_conflict')) class PageTextForm(forms.ModelForm): def clean(self): cleaned_data = super(PageTextForm, self).clean() page = cleaned_data.get('page') name = cleaned_data.get('name') if page.pageimage_set.filter(name=name).exists(): self.add_error('name', forms.ValidationError(_('Cannot be the same name as an existing layout image on the page'), code='name_conflict')) This accomplishes two of the three things I need. 1) For each page, no two images can have the same name, and no two texts can have the same name. 2) When editing a page in the admin, you cannot rename an image to have the same name as … -

ManyToMany field returns None despite having a value
I have 2 classes: categories and pizzas. One of them is a list of categories for the object and another one is the object. Problem is, when I call an object, I can see all the fields except that ManyToMany field returns catalog.Category.None instead of the assigned value. Here is my models.py: class Category(models.Model): CLASSIC = 'Classic' VEGETARIAN = 'Vegetarian' SPICY = 'Spicy' TYPE = [ (CLASSIC, 'Classic'), (VEGETARIAN, 'Vegetarian'), (SPICY, 'Spicy') ] type = models.CharField( max_length=100, choices=TYPE ) def __str__(self): return self.type class Meta: verbose_name_plural = 'Categories' class Pizza(models.Model): name = models.CharField(max_length=100) price = models.IntegerField() size = models.OneToOneField( Size, on_delete=models.CASCADE, primary_key=True ) category = models.ManyToManyField(Category) def __str__(self): return f"name = {self.name}, size = {self.size}, category = {self.category}" And here is my shell output: >>> from catalog.models import Pizza >>> from catalog.models import Category >>> pizza = Pizza.objects.all() >>> pizza <QuerySet [<Pizza: name = Chicken, prices = 8, 10, category = catalog.Category.None>, <Pizza: name = Pepperoni, prices = 8, 12, category = catalog.Category.None>, <Pizza: name = Mushroom, prices = 7, 9, category = catalog.Category.None>]> >>> cat = Category.objects.filter(pizza=1) >>> cat <QuerySet [<Category: Classic>]> >>> cat = Category.objects.filter(pizza=2) >>> cat <QuerySet [<Category: Classic>, <Category: Spicy>]> -
How to make QuerySet JSON serializable?
I have a problem with creating a new object in my Rest Framework. As much I as understand, when I tried to overwrite item's field so it could have all the items that are in my database. I thought, that this would work, and it showed me the working page and I could choose an item. But when I tried to post it to create a new object, it said "Object of type 'Item' is not JSON serializable" I was trying to figure it out, how to convert Item.objects.all() into JSON data. But nothing helped me. I understand, that this isn't really hard to do, but I can't figure it out on my own. So I ask for your help, how to solve this problem? Here's my serializer from rest_framework import serializers from items.models import OrderItem, Item class OrderItemSerializer(serializers.ModelSerializer): item = serializers.ChoiceField(choices=Item.objects.all()) class Meta: model = OrderItem fields = ('item', 'size', 'quantity', 'id') -
Django - using 1-1 relationship method to create two different user profiles, same authentication
I have a Django project in which I have currently used the default user authentication process, and extended it to allow for user profiles. I now want to create profiles for two different types of users, e.g. User type 1: = WP. User type 2: = W. I have looked at some of the suggested solutions but wanted some specific guidance on my particular scenario and code. As I understand it, there are three ways of attempting to do this 1. Proxy Model 2. 1-1 Relationship Method 3. Custom User Model. I want to use option #2 - 1-1 Relationship Method and avoid the other two, with the objective being to a) allow users to log in b) allow a user to specify if they are user type 1 (WP) or user type 2 (W) c) If a user is user type 1 (WP) they are directed to a WP profile, and if a user is user type 2 (W) they are directed to user type 2 (W) profile. I currently have this in my models.py (for users) from django.db import models from django.contrib.auth.models import User from PIL import Image from django import forms class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) … -
Accessing containerized Django app from ECS public IPv4 endpoint
I have a dockerized django app that is stored in ECR.

How can I make my django channels websocket server work over ssl?
I'm setting up a web application that has a chatroom system. I originally followed the tutorial here: https://channels.readthedocs.io/en/latest/tutorial/index.html It worked flawlessly in development, but I had to use daphne to get it to work when I deployed the app because I'm using apache. sudo daphne -b 0.0.0.0 -p 81 myapp.asgi:application But when I used certbot to get ssl certificates for https, I started getting the following console errors whenever I try to send a message: Mixed Content: The page at: https://example.com/home/chat/46508f6fc17b04ad04ba0e8e5095e4b233944ed3d4145e5501ada21bab7042c6/' was loaded over HTTPS, but attempted to connect to the insecure WebSocket endpoint 'ws://example.com:81/ws/chat/46508f6fc17b04ad04ba0e8e5095e4b233944ed3d4145e5501ada21bab7042c6/'. This request has been blocked; this endpoint must be available over WSS.

Django quiz: Save user's choice and include them in a result
I want users to take a series of questions each with different choices to select from. Then, after the last question a page containing results should be displayed that is based on the user's choices (for simplicity let's say the user's score). I am new to Django and I am unsure on how to save the user's choices, so I can work with them. I read some posts about this, but couldn't find a final solution. First of all, will it require a setup/login feature to be able to save user data? Also, will I need some sort of customized UserModel (see code below as an example) and/or a class that contains question_id, answer_id, user_id? My models: class Question(models.Model): question_text = models.CharField(max_length=200) def __str__(self): return self.question_text class Choice(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) choice_text = models.CharField(max_length=200) def __str__(self): return self.choice_text class UserAnswer(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) answer = models.ForeignKey(Choice, on_delete=models.CASCADE) user = models.ForeignKey(User, on_delete=models.CASCADE) answered = models.BooleanField(default=False) def __str__(self): return str(self.question) + "_" + str(self.answer) class UserProfile(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) score = models.IntegerField(default=0) -
Django: Filter data based on expiration date coming within next 1 week and 2 weeks
I have a model class: class Products(models.Model): product = models.Charfield( field specs here . ) expiration_date = modelsDateTimeField ( . field specs here . ) Now I want the users to be able to see all the products which will expire in 1 week or/and 1 month or/and 3 months from today. I have already tried: from django_filters import rest_framework as filters expiration_date_after = filters.DateFilter(field_name='expiration_date', lookup_expr='gte') expiration_date_before = filters.DateFilter(field_name='expiration_date', lookup_expr='lte') with this, I have to pass two parameters in the url: /products/?expiration_date_after=2019-06-06&expiration_date_before=2019-06-12 But I want to pass in the url only 1 or 2 or 3 which will display data for 1 week, 2 weeks and 3 weeks . So if i pass products/1 . it should filters expiration date for next 1 week. and if i pass products/2 . it should filter expiration date for next 1 month. I am new to django.... So please let me know what is best approach to this problem. -
