DRF doesn't update instead create new instance in modelserializer
Searched throughout SO to find the matching questions doesn't answer mine as there are only few explanations. So hoping to get an answer here. I have a model named "testcase" with pk set as "testcase_name". On update operation in the serializer, instead of updating a new instance is created everytime. I suspect it is because of the pk. serializer.py class TestcaseSerializer(serializers.ModelSerializer): class Meta: model = testcase lookup_field = 'testcase_name' fields = ("testcase_name", 'description') def update(self, instance, validated_data): print(instance) # returns test1 as it is ithe current pk # ret = super(TestcaseSerializer, self).update(instance, validated_data) [setattr(instance, key, value) for key, value in validated_data.items()] instance.save() print(instance)# returns test2 as the testcase_name is changed to test2 #instead it is a new instance rather than the old instance getting updated return instance models.py class testcase(models.Model): testcase_name = models.CharField( max_length=20, primary_key=True) description = models.CharField(max_length=100, blank=True) def __str__(self): return self.testcase_name views.py class Testcaseviewset(viewsets.ModelViewSet): queryset = testcase.objects.all() serializer_class = TestcaseSerializer lookup_field = 'testcase_name' Is there any way to solve this in the serializer itself not from the views. -
Chmod fails when using fuse mount as media directory
I'm trying to use a remote FTP as a Django media source in docker. I have mounted a directory: /mnt/ftp_media with curlftpfs: curlftpfs -o allow_other user:pass@host /mnt/ftp_media I've noticed that when trying to upload a file, it actually does get created on the remote, but django fails on chmod with: Operation not permitted I've tried to directly execute chmod inside the mount: cd /mnt/ftp_mount chmod 666 some_file.txt But then I also get an error: chmod: changing permissions of 'some_file.txt': Operation not permitted Even as a root user. I've tried to remount with different users, but it always yields the same results. Is it just that you should not use chmod in fuse mounts? -

Django - deployment on Heroku returns different HTML than local host
I have a Django app that works great on localhost. When deployed the Heroku, for some reason the app returns different HTMLs. A few examples: I have a form with button type submit. This is the template <button type="button" page="{{request.resolver_match.view_name}}" type="submit" id="bullets_submit" class="btn btn-primary px-5 py-2"> Next Step </button> In localhost everything works well but on Heroku the HTML I receives is without the type="submit". Same button just without this attribute. I have a for loop that iterates on a model and create a li <div class="h5 mx-4 px-3 bg-white" style="position: absolute; top: -20px;"> About the role <a href="{% url 'app:responsibilities' description.pk %}" type="button" class="btn btn-outline-light px-2 text-muted border border-0"><i class="far fa-edit"></a></button> </div> <div class="border border-primary rounded shadow p-2 pt-3 m-2"> <ul> {% for responsibility in description_responsibilities%} <li>{{responsibility}}</li> {% endfor %} </ul> </div> On Heroku, even though the <i class="far fa-edit"> is clearly outside of the for loop, it still get generated several times in the HTML I receive from the server, as if it was inside the for loop. Any idea what might cause this weird behavior? Or how I can debug it? -
Can't get Django REST to save POST object request in model

Django Email Not Working on Production Server
I have recently deployed a site that I developed in Django onto a production server running Ubuntu and Apache. The site functioning in every respect with the exception of sending emails wherever I configure an email to be sent, the page keeps loading and nothing happens although in the back end whatever information was made is saved like the contact us. On the local host emails are working perfectly fine and on the deployed site it is just not sending and the page keeps loading endlessly. Here is an example of the contact us config views.py def contact_us(request): if request.method == 'POST': # check post form = ContactForm(request.POST) if form.is_valid(): data = ContactMessage() # create relation with model data.name = form.cleaned_data['name'] # get form input data data.email = form.cleaned_data['email'] data.subject = form.cleaned_data['subject'] data.message = form.cleaned_data['message'] data.save() # save data to table messages.success(request, "Your message has ben sent.

Writing a cleaner function in python, a parameter to be either a set or a value
I have a struggling with a way of writing this function much cleaner and to make this function for the parameter objs to can be either a QuerySet or an single object, in case when the objs parameter is an set of objects I want to go with the for loop but in the case when is a single object I want to create the date parameter without looping, and also I am not sure if the try block is the good way for checking if the object with these information is already in db or not and if it's not I want to create it with these dates.

In Django admin, how can I filter a MultipleChoiceField depending on a previous MultipleChoiceField?
In my django website, I have 3 classes: Thing, Category and SubCategory. Thing has 2 ForeignKeys: "Category" and "SubCategory" (such as Car and Ferrari). SubCategory has 1 ForeighKey: "Category" (Ferrari is in the category Car) When I create an instance of Thing in the Admin part and when I choose a Category, I would like that the "SubCategory" field only shows the SubCategories linked to the Category I chose.

Using different color than bootstrap default color scheme - Django Python
Pretty new to Django, Recently, while building a website using Django, I created the navbar and used bootstrap. Just to make it look better. However, it seems that I'm forced to use bootstrap default color scheme. I want to change the navigation bar background color to a color tag, inside the base.html file. Google left me empty-handed. With many advices on overwriting and adding your custom.css (which a lot of people aware you of doing so as it is not recommended). I tried adding custom script into the html file, failed. <script> .navbar-custom { background-color: #9f6967; } </script> I would appreciate help on (maybe) creating a custom.css file. So far the nav-bar is the default bootstrap navigation bar script from their website. <nav class="navbar navbar-expand-lg navbar-dark bg-dark"> Other than dark/light/other colors from the scheme, there isn't any way to add a color tag. (specific : #9f6967) -
How to upload an image in django using S3Boto3Storage where the path is set dynamically from the view in django
I'm wanting to save images to an S3 bucket using the session_key as the directory inside the bucket, in django. I have created a test page that uploads an image to a set location in the bucket but don't know how to use the session_key to set the upload location dynamically. I've looked at the docs for django-storages and I can see a way to do this if it wasn't for the fact that I am using a ModelForm.

Django and React authentications system
I am intermediate Django web developer. I am trying my hands on working with both Django and react at the same time. It's all good if you are using the rest framework, but I am stuck with the authentication system. I love Django built-in UserCreationForm but the solutions(JWT) I find don't seem to utilize Django forms. I tried Django Djoser and Knox; my problem Djoser throw parse error when the password is complex, i.e. include symbols, and both don't utilize Django forms. Note: It's okay if your solution does utilize Django forms, but it's better if it does. I should be able to login to Django admin panel too. I should be able to upload images(profile pic) while registering user. And that's it any help is really appreciated and also English is not my first language, so forgive me if I made any mistake. Thanks -

HTML video Tag range not working propery in Django
Am creating a small website, where Django returns a movie and the video Tags handles and play the movie. The video Tag plays the movie but the video tag range or slider doesn't work.

django drf testing social oauth2 with google
I'm trying to test drf-social-oauth2's integration with Google via python manage.py test with the following test class: class DRFSocialOAuthIntegrationTest(TestCase): def setUp(self): self.test_user = UserModel.objects.create_user("test_user", "test@user.com", TEST_USER_PASSWORD) self.application = Application( name="Test Application", redirect_uris="", user=self.test_user, client_type=Application.CLIENT_CONFIDENTIAL, authorization_grant_type=Application.GRANT_PASSWORD, # https://github.com/jazzband/django-oauth-toolkit/blob/master/oauth2_provider/models.py ) self.application.save() # Every test needs a client. self.client = Client() def tearDown(self): self.application.delete() self.test_user.delete() def test_drf_social_oauth2_integration(self): '''Following testing steps found at curl -X POST -d "grant_type=convert_token&client_id=<django-oauth-generated-client_id>&client_secret=<django-oauth-generated-client_secret>&backend=google-oauth2&token=<google_token>" http://localhost:8000/auth/convert-token''' def convert_google_token(self): ''' Convert Google token to our access token curl -X POST -d "grant_type=convert_token&client_id=<client_id>&client_secret=<client_secret>&backend=google-oauth2&token=<google_token>" http://localhost:8000/auth/convert-token ''' return self.client.post( '/auth/convert-token', { 'grant_type': 'convert_token', 'client_id': self.application.client_id, 'client_secret': self.application.client_secret, 'backend': 'google-oauth2', 'token': <google_token> } ) That seems to work fine, but I have to keep feeding it the google_token by manually navigating to https://developers.google.com/oauthplayground/?code=<my_code>&scope=email+profile+https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fuserinfo.email+https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fuserinfo.profile+openid&authuser=0&prompt=consent#: Once there, I click on the 'Exchange authorization code for tokens' button, get the access token, and paste that access token into the tokenparameter of the request inside convert_google_token(). This doesn't feel very automated. I'm not sure if I should just click the checkbox so that the access token is refreshed automatically and therefore never have to edit it in convert_google_token(). Or maybe I'm supposed to get that access token programmatically. But I believe that would entail getting the authorization code first, which …
