How can I serialize custom many-to-many model django?
I have 3 tables on data base: News, CustomUser(not important) and Comment: class News(models.Model): date = models.DateTimeField(auto_now_add=True) title = models.CharField(max_length=200) text = models.TextField() image = models.ImageField(upload_to='news_images/', blank=True) author = models.ForeignKey(CustomUser, on_delete=models.SET_DEFAULT, blank=True, default=1) tags = models.ManyToManyField(Tags, blank=True) published = models.BooleanField(default=False) comments = models.ManyToManyField( CustomUser, related_name='author', through='Comments.Comment', blank=True, ) class Comment(models.Model): date = models.DateTimeField(auto_now_add=True) text = models.TextField() author = models.ForeignKey(CustomUser, on_delete=models.SET_NULL, null=True) event = models.ForeignKey(News, on_delete=models.CASCADE, parent_link=True) As you can see, comment is a custom many-to-many model, that links Users and News, and adds some extra data (text of comment itself). I using DRF, so I need to serialize it. I need news serializer to include list of comments with all their fields(like author fields as you can see below on the screenshot).But when i getting one of the news I see that: {"id":2,"author":{"username":"Admin","email":"alexsiid29@gmail.com","first_name":"","last_name":""},"tags":[],"comments":[1],"date":"15.08.2021 10:10","title":"Тест2","text":"тестовая 2","image":"http://127.0.0.1:8000/news_images/%D0%91%D0%B5%D0%B7%D1%8B%D0%BC%D1%8F%D0%BD%D0%BD%D1%8B%D0%B9.png","published":true} Comments: "comments":[1] And when I printing during the view-function execution: self.object = News.objects.filter(pk=pk).first() print(self.object.comments.all()) I getting this: <QuerySet [<CustomUser: Admin>]> So, instead of normal representation of comments I get the authors ID. There is my serializers: class CommentSerializer(serializers.ModelSerializer): author = CustomUserSerializer(source='author.id') event = NewsSerializer(source='event.id') class NewsSerializer(serializers.ModelSerializer): author = CustomUserSerializer(read_only=True) tags = TagSerializer(required=False, allow_null=True, many=True) comments = serializers.PrimaryKeyRelatedField(allow_null=True, many=True, read_only=True) So, how can I serialize this … -
Django Failed to establish a new connection <urllib3.connection.HTTPSConnection>
I use Django 2.2 and I have an api that is connected to two Esx servers. a = 10.131.171.80 b = 10.131.171.90 everything works perfectly, except that during my test when I add a third fake server, it tells me that the server does not respond because connection time out.

Best strategy for saving profile picture using Django
This may be a very trivial question but its something I could not find a convincing answer. I am building a web application with Django as the backend. My application has a user profile which can take a profile picture. I have to decide on cloud storage solution. I wanted to ask what is best strategy for such a task. Storing on cloud, or storing on the web server itself. I want to know the pros and cons (ignoring cost). Also if I decide to go with cloud storage, what are the best for such a task. Here its profile picture (limiting single picture to say less than 1MB), so taking into account latency etc. I have worked on AWS S3 and have a solution in place to store these images on S3. But I wanted to have opinions. -

Django selenium (StaticLiverServerTestCase): tests run together fail but pass if run individually
I write tests with StaticLiverServerTestCase for my Django application. My issue: tests runs together fail while pass when run individually. I have read much about this behavior on SO but none of answer/comments help. It seems that issue may come from shared files/fields/data. I have tried using setUpClass/tearDownClass class methods as well as setUp/tearDown methods. Using fixture did not resolve anymore. I also tryed to make individual class for each test instead of one class with many test ethods but doesn't work anymore. My tests involve Ajax calls and I think this is related. For example, in the 2 tests below: L_new_patient_is_created_from_index_page_TestCase run first (I don't know why) and pass. L_search_form_exist_refresh_TestCase fail L_search_form_exist_refresh_TestCase will call an ajax view to display a table and change the url with JQuery ($(location).prop('href', redirect_url);). So if the user refresh the page (F5), it will be redirected to another page that hit the changed url and display the same table. What happen when the 2 tests are run together is that url is not changed so refresh do not redirect to the right page. How can I make my tests trully independant? class L_search_form_exist_refresh_TestCase(StaticLiveServerTestCase): fixtures = ['dumpdata.json'] port = 8000 # host = "0.0.0.0" # … -

How do I access User Model field in the Serializer of extended User Model in Django Rest Framework?
I am creating a simple registration/login app in Django Rest Framework using Rest APIs with Django Rest Knox's authentication, in which, upon registration, user will also upload a CSV File (which is an optional field). I have a Person Model which is an extended (derived or OneToOne) Model of User Model and has FileField for the file to be uploaded. I have two ModelSerializers, one is based on User Model named MainRegisterSerializer and serializes username, email and password fields, and the other is based on Person Model named RegisterSerializer, which serializes FileField and register field (that is initialized with MainRegisterSerializer class's constructor. Now, in views.py, I am accessing the RegisterSerializer, to get the data from front that which includes username, email and password fields from User Model, and FileField from Person Model. But, when I enter data in front-end and upload the file, and click on POST button, I get the following error: KeyError at /api/v1/register 'username' on the code line user = User.objects.create_user(validated_data['username'], validated_data['email'], validated_data['password'], validated_data['file']) in serializers.py file.

How to style an Image Field button in Django App
I want to style my Image Field Button (Choose File) with CSS. Currently, its displaying in the default theme. I am using Bootstrap V5.0.1, Django V3.2.12, Python 3.7.6. First, I tried to identify or add a class or id which I can add and style the button regularly but was unable to add as the button was added by Django Image Field. The Code in my forms.py is given below: from django import forms class ImageUploadForm(forms.Form): image = forms.ImageField(label='') Then I used the Hover functionality of the Chrome Developer Tools to identify any leads and found that the button and its area had 2 id's #file-upload-button and #id_image. I tried to add CSS to the above-mentioned id's but did not get the result i desired. I want to style the Choose File Button Below also if possible can i add any bootstrap to the button, any help would be appreciated! Thanks.

Django authentication with .NET httpWebRequest and HttpWebResponse
I have an issue with the login with the "POST", following this link here: Django Authentication from .NET using HttpWebRequest and HttpWebResponse via HTTP POST Without "POST", I don't seem to get logged on because the received ResponseStream is still on the login page. Adding the request method "POST" caused me to be caught in "The remote server returned an error: (403) Forbidden." Also tried .Credentials rather than "Dim postData As String = "username=" & m_username & "&password=" & m_password" but nothing helps. Trying AllowAutoRedirect True/False, PreAuthenticate True/False doesn't help at all. myRequest.AllowAutoRedirect = True myRequest.Method = "POST" myRequest.PreAuthenticate = True myRequest.Credentials = New NetworkCredential(username, password) I am sure I can access the site with the password I am using. Any advice? -
Monitoring of loggings using Django
I have a pipeline of steps that I want to monitor and also alert the user in the front end about the process.

Is there a better approach to that problem ? -

Django Rest Framework method in action decorator needs be specified in class http_method_names
DRF version is 3.11.2 I was working on some existing code to add an extra "delete" action to a viewset, but I got 405 Method not allowed, consider the following made up example class UserViewSet(ViewSet): .... queryset = User.objects.all() http_method_names = ['get', 'post'] @action(detail=True, method=['delete']) def delete_profile(self, request, pk=None) Profile.objects.get(user=pk).delete() .... Like I said, when I make a delete method call to /user/123/delete_profile, I get 405 Method not allowed, however, if I add delete to http_method_names as below, it works fine. class UserViewSet(ViewSet): .... queryset = User.objects.all() http_method_names = ['get', 'post', 'delete'] @action(detail=True, method=['delete']) def delete_profile(self, request, pk=None) Profile.objects.get(user=pk).delete() .... But this is not ideal as I don't want to allow "delete" operation on the User, whilst I can overwrite the delete method on the viewset to avoid user being deleted, this is not very elegant. So the question is, is this a bug or by design? -
