When I include a template in another template how can I pass the path of a source file?
I have two templates that go together, one inside the other. The inner one has an icon that needs to change according to the content of the parent template. I've tried to pass the icon path using a variable: src="{% url 'main_bar_icon' %}"> and I added this line of code in the parent template: {% with main_bar_icon='../static/dist/img/logout-icon.svg' %} {% include 'main_bar.html' %} {% endwith %} So, this is my inner template: {% block main_bar %} <a href=""> <img class="app-main-bar-icon" src="{% url 'main_bar_icon' %}"> </a> {% endblock main_bar %} And this is my parent template: {% block content %} {% with main_bar_icon='/dist/img/logout-icon.svg' %} {% include 'main_bar.html' %} {% endwith %} {% endblock content%} In the browser I get this: <img class="app-main-bar-icon" src(unknown) alt="icon"> -
Django 2 Many to Many relationships
I'm working on a project using Python(3.7) and Django(2.1) in which I need to build a relationship between users and organizations. I'm using the default Django User model and a profile model to add extra information to users. Many users can join an organization and an Organization can have many members, a user can create an Organization, these behaviors I need to implement, according to my understanding we need to build a ManyToMany relationship for Organizations model, but don know how to use this relationship to display the information, e.g display a user's organizations on his profile page. Here are my models: class Organization(models.Model): name = models.CharField(max_length=255, blank=False) users = models.ManyToManyField(User, related_name='members', null=True) def __str__(self): return self.name class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) image = models.ImageField(default='media/default.jpg', upload_to='profile_pics') goals = MultiSelectField(choices=goals_choices, default='') def __str__(self): return f'{self.user.username} Profile' -

How to add non-standard languages to Dango?
Tell me, how can I add a language to Dango, which is not supported by the standard? In the file settings.py identified: ...

What's the right way for a RESTful app to upload files?
I'm building a React application along with a Django REST API, and I wanna use Cloudinary for my image management/storage. My question is: What would be the right way to do it? 1) The react application through the React SDK provided by Cloudionary upload directly to Cloudionary and then the response is sent to my Django Rest app. 2) The react application uploads directly to my Django Rest App and then my Django Rest app uploads to Cloudionary through the Django SDK provided by Cloudionary. What's the right way to do it and what would be the benefits of one over the other? Or is it really indifferent? -
Disable atomic transaction in Django 1.11 change view

How to convert a lookup to an expression to use in `QuerySet.annotate`?
The subject may be a little bit obscure, so here is an example. Let's say I have a model: class TestModel(models.Model): user = models.ForeignKey(User, ...) I want a QuerySet containing a has_user field that would basically map to the following SQL query select id, user_id is not null as has_user from app_testmodel How can I explain this user_id field to Django when using QuerySet.annotate? I am aware that Django has concepts like models.F, models.Q, models.lookups, models.expressions etc., but I am unable to understand how to apply them in my case. To the best of my knowledge, this is a question of converting a "lookup" to a boolean "expression" where A "lookup" is something like 'user_id__isnull' or lookups.IsNull(models.F('user_id')) in Django ORM language. An "expression" is something like expressions.ExpressionWrapper(?, output_field=models.BooleanField()). So far I only managed to convert the user_id is not null expression to case when user_id is not null then true else false end, which maps to Python code like this: from django.db import models from django.db.models import expressions # ... qs = TestModel.objects.all().annotate(has_user= expressions.Case( expressions.When( user__isnull=False, then=expressions.Value(True), ), default=expressions.Value(False), # # Tell Django the expected type of the field, see `output_field` in # https://docs.djangoproject.com/en/2.1/ref/models/expressions/ # output_field=models.BooleanField())) But it is an … -
How to handle Django through_fields with non-fixed direction
Django's ManyToManyField through_fields attribute takes a tuple of the format(foreign_key_to_intermediate_model, foreign_key_from_intermediate_to_target_model) I have a data-structure that essentially looks like this (simplified for the example) class Person(models.Model): name = models.CharField() relations = models.ManyToManyField( Person, through='Relationship', through_fields=(???)) class Relationship(models.Model): child = models.ForeignKey(Person) parent = models.ForeignKey(Person) holiday_card_sent = models.BooleanField() I need to annotate the relationship (did they send a card), but a single person will be both a child and a parent in different relationships. The relationship has a directionality, but not the person. A person will also have multiple children and multiple parents. It feels like I'm missing something obvious here. Should I just be creating my own __init__ method to handle this? Will that lose out on lookup performance that Django would normally give? -

Signal receiver works in shell but not in frontend
I've been following these instructions to associate a profile to each user upon user creation. When I instantiate and save a user in the shell, the associated profile get saved as well. However, when I sign up a user in the front end, then no associated profile gets created. Furthermore, the console does not execute a print statement embedded in the receiver. I verified that a new user is indeed added to the database. Debug-toolbar does list "post_save" under the sent signals, and also lists desired receiver "create_user_profile" under the corresonding receivers. What could be going on here? The relevant portion of my signals.py is from django.contrib.auth.models import User from django.db.models.signals import post_save from django.dispatch import receiver from people.models import Profile @receiver(post_save, sender=User) def create_user_profile(sender, instance, created, **kwargs): print(f"create_user_profile: this was called with instance={instance}") if created: Profile.objects.create(user=instance) The contents of the associated apps.py file are from django.apps import AppConfig class PeopleConfig(AppConfig): name = 'people' verbose_name = ('people') def ready(self): import people.signals # noqa and my init.py file has default_app_config = 'people.apps.PeopleConfig' -

Get '_set' for a many-to-many relationship with a through

Django: Frequent use of include template tag - how much is too much?
I noticed that I started using include template a lot. One of my template files has 20+ include tags. Some of them are for modal dialogs that in turn have include for different form field sets. I am also using basically the same buttons with different data attributes so these are also done with include tags. Some my "fragments" that I use with include have around only five lines of HTML code. I worry if this is too much and can negatively affect performance (since Django loads another files, etc..) For example whis is markup of one of my HTML fragments I am using with include: <div class="form-group"> <input type="url" class="form-control" id="video-link-input" name="video_link" placeholder="YouTube link"> </div> <input type="hidden" id="video_id" name="video_id" value=""> <img class="img-fluid img-thumbnail" id="video-img-preview"> Hope the question is not too broad. I would just like to avoid possible bad practice. -
Django how to serialize and validate external xml data
i have "problems" validating external xml. What i want is to fetch data from an external rss site, validate if all fields are present and save it to the database then. The problem i am having is that i am not sure how can i send the xml data to my validator. I tried in different ways but it was not working. https://api.foxsports.com/v1/rss?partnerKey=zBaFxRyGKCfxBagJG9b8pqLyndmvo7UU&tag=nba This is an example of the rss i am trying to parse. Here is my code: import json import requests import xml.etree.ElementTree as ET from rest_framework.views import APIView from rest_framework.response import Response from rest_framework import status, generics class Test(APIView): def get(self, request, format=None): response = requests.get( channel.url ) print(response.status_code) if response.status_code == 200: xml = response.text.encode("utf-8") tree = ET.fromstring(xml) for child in tree.iter("item"): serializer = RssSerializer(data=child) if serializer.is_valid(): serializer.save(parsed_xml) The problem here is that my serializer is always not valid, no matter what i do. I kind of got around this problem when i wrote a small helper function that is manually extracting fields from the request. It looks like this: def parse_xml(self, node): parsed_json = { "title": node.find("title").text, "description": node.find("description").text, "link": node.find("link").text, "pub_date": node.find("pubDate").text, "guid": node.find("guid").text, } return parsed_json Basically i just added this line parsed_xml …
