How to customize the serializer data of an onetomany relationship in django
I define the serializer for the image model and call it up to the postserializer to give data at once when the postserializer is called. There is no problem with the operation, but I don't give json data as I want. Now I give it to you like this is it. { "pk": 0, "author": { "id": 0, "email": "", "username": "", "profile": "url", "following": 0, "followers": 0 }, "title": "", "text": "", "view": 0, "images": [ { "image": "url" }, { "image": "url" }, { "image": "url" }, { "image": "url" } ], "like_count": 0, "comment_count": 0, "liker": [ 0, 0 ], "tag": null, "created_at": "2020-10-06T21:46:48.039354+09:00" }, I want this. { "pk": 0, "author": { "id": 0, "email": "", "username": "", "profile": "url", "following": 0, "followers": 0 }, "title": "", "text": "", "view": 0, "images": [ url, url, url, url ], "like_count": 0, "comment_count": 0, "liker": [ 0, 0 ], "tag": null, "created_at": "2020-10-06T21:46:48.039354+09:00" }, How will json come out the way I want? Here is my code. serializers.py class ImageSerializer (serializers.ModelSerializer) : image = serializers.ImageField(use_url=True) class Meta : model = Image fields = ('image', ) class CommentSerializer (serializers.ModelSerializer) : comments_author = userProfileSerializer(read_only=True) class Meta : model = Comment … -
Setting up tests to test API endpoint in DjangoRest
I am struggling setting up tests for a DjangoRest API endpoint. This is the model: class RestaurantReview(models.Model): review_author = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) maps = models.ForeignKey(Restaurant, on_delete=models.CASCADE) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) My test: class CreateReviewTest(APITestCase): def setUp(self): self.user = User.objects.create_user(username="TotoBriac", password="verystrongpsw") self.token = Token.objects.create(user=self.user) self.api_authentication() def api_authentication(self): self.client.credentials(HTTP_AUTHORIZATION="Token " + self.token.key) def test_create_review(self): self.data = {"maps": "ChIJd230zfzz5UcRz8XVIZjiVzY", "review_author": "TotoBriac"} response = self.client.post("/api/restaurant_review/", data = self.data ) self.assertEqual(response.status_code, status.HTTP_201_CREATED) But my test fails and I get this error: AssertionError: 400 != 201 Since it's a 400, can it be also a 404 or a 403? I have another test testing user creation and it's working fine. So I don't think is db access related. Because I run my test this way python3 manage.py test --keepdb (I am testing a PostgrSql db deployed on heroku therefore I had to create another db just for testing), I can't use the verbose -vv and can't figure out was is the issue with my test. -
Triyng to slugify url from title posts in a Django blog
I have a blog in Django and realised that I would like to have the url of the articles in slug with the title's name. I don't really know how to proceed. Another problem is that I already have several posts done with article/int:pk. Tried to make a url camp in the database and a function in order to transform the title and slugify it, but I don't really know how to get it done or how to continue.

Similar view to admin for normal users in django
How can I give a similar view to normal users so they can change some data for some models.

Javascript cookie isn't saved
while working on my first django project I got stuck dealing with cookies on javascript. I'm building a kind of e-commerce website and trying to improve the guest user interaction. I tried to create to cookie that in the future will contain the guest user cart and can't see it when I check the browser cookie so I think the cookie is now saved at all: <head> <meta charset="utf-8"> <title>Webpage</title> <script type="text/javascript"> function getCookie(name){ var cookieArr = document.cookie.split(";"); for (var i = 0; i < cookieArr.length; i++) { var cookiePair = cookieArr[i].split("="); if (name == cookiePair[0].trim()){ return decodeURIComponent(cookiePair[1]); } } return null; } var cart = JSON.parse(getCookie('cart')); if (cart == undefined){ cart = {} console.log("Cart was created!") document.cookies = 'cart=' + JSON.stringify(cart) + ";domain=;path=/"; } // console.log('Cart:',cart); </script> </head> Hope someone can help me, Thanks ahead. -

How can I import component from variable or props - Dynamic router
Context for a good solution (short question in bottom). I have a database (API) which generate list of data of apps like AppA, AppB, AppC, etc. with their name, path... With a map, I generate (react router) links to these apps based on this data list (in the main <App/>) and front. With another identical map (below), I have made the router which should call the App based on the route and app name: function(Router) { const [routes, setRoutes] = useState([]); useEffect(() => { fetch("MyAPI") .then(res => res.json()) .then((result) => {setRoutes(result.results)} ) }, []) // The route for each app and after the map, the route to the home with these links return ( <Switch>{ routes.map(result => <Route exact path={"/"+result.route} key={keygen(16)}> <AppCaller name={result.name} id={result.id} path={"/"+result.route}/> </Route> )} <Route exact path="/"> <App /> </Route> </Switch> ) } export default Router My first problem is I cannot neither give a component Name like <result.name/> from the API to call this component in the Router nor import dynamically this component. My first solution was to create another component <AppCaller/> with the name and path as Props to remove the component problem like this : import React from "react"; import Window from "./dashComponents" import … -

How to make Django 3, channels and uvicorn work together

Django: Identical text not unique on binary level
I have a modal with a field my_field which has to be unique. I´ll check if a task has to be executed later onwards by checking if the entity already exists: class MyModel(models.Model): my_field = models.CharField(max_length=75, unique=True) And later: if MyModel.objects.filter(my_field=my_value).exists(): pass # execute task and save it under the value name in question else: pass The values I need to compare here are received via two different 3rd party apis. Now I have the problem, that the "human readable" same text is not detected as identical, which makes the unique attribute fail (in the sense of it does not let the save fail) and of course also the "does it exist? check". So after a while, I hacked into django shell and converted two of the values into binary code and that way they are not the same. So I read about normalization and came up with this: class MyModel(models.Model): ... def save(self, *args, **kwargs): if self.pk is None: self.my_field = unicodedata.normalize('NFC', self.my_field) ... And before I query the DB, I normalize the received value the same way. Still I get instances with the same "human readable text" but different binary code and the problem persists. How can I … -
Django: How to decide between class-based and function-based custom validators?
This is a beginner question. I'm working on a website that allows users to upload a video to a project model (via ModelForm) and I want to validate this file correctly. I originally declared the field in this way: from django.db import models from django.core.validators import FileExtensionValidator def user_directory_path(instance, filename): """ Code to return the path """ class Project(models.Model): """ """ # ...Some model fields... # Right now I'm only validating and testing with .mp4 files. video_file = models.FileField( upload_to=user_directory_path, validators=[FileExtensionValidator(allowed_extensions=['mp4'])] ) But I read in several places that it was better to use libmagic to check the file's magic numbers and make sure its contents match the extension and the MIME type. I'm very new to this, so I might get some things wrong. I followed the validators reference to write a custom validator that uses magic. The documentation also talks about "a class with a __cal__() method," and the most upvoted answer here uses a class-based validator. The documentation says that this can be done "for more complex or configurable validators," but I haven't understood what would be a specific example of that and if my function-based validator is just enough for what I'm trying to do. I … -

DjangoLoop through an app urls in template
I'm django beginner working on my third project, but running into small issue. Basically, i have an app called 'projects' which contains html templates that the CBV needs for CreaeView, UpdateView, DeleteView and ListView. My base templates inherits from a menus file which contains all the navigation menus needed for the website. Now my issue is i wanted to make projects menu active (css) for all the crud operations of project app. i did this and it's working as intended: {% url 'projects-list' as url %} {% url 'project-detail' project.pk as url1 %} {% url 'project-create' as url2 %} {% url 'project-update' project.pk as url2 %} <a href="{{ url }}" {% if request.path == url or request.path == url1 or request.path == url2 or request.path == url3 %} class="item active" {% endif %}><span class="icon"><i class="fa fa-folder-o"></i></span><span class="name">Projects</span></a> But i don't like it this way as it's too repetitive and i want to add a lot of menus like this in future. What is the easiest way to loop through all links of app? Thanks in advance. Best regards. -

How to set virtualenv to stay active on a host server
I created a website that uses vuejs as the frontend and django as the backend with another service running behind everything that im making api calls to. So django is setup in a way to look at the dist folder of Vuejs and serve it if you run manage.py runserver. but the problem is that my service that I created is in python and it needs to run in a virtualenv in order to work (It uses tensorflow 1.15.2 and this can only run in a contained environment) I'm sitting here and wondering how I can deploy the django application and keep the virtualenv active and Im coming up with nothing, I've tried doing some research on this but everything I found was not relevant to my problem. I've deployed it and when I close the ssh connection the virtualenv stops. If there is anyone that can enlighten my ways I would appreciate it.
