How can I serialize ManyToManyField in django?
I want to make a post model and show the person who clicked like. So after creating models and serializers, the server runs and the following error occurs. TypeError: Direct assignment to the forward side of a many-to-many set is prohibited. Use liker.set() instead. I think the error occurred during the serialization of ManyToManyField, but I don't know the solution. How can I implement the features I want?

HTML page or JSON object as response of single API depending on the type of incoming request
I'm planning to create a service with Django which can serve REST APIs and a web application. Right now I'm in a situation where a function needs to send JSON in response if called from another application and should serve HTML page with the same JSON rendered if requested from a web browser. Is it possible to differentiate the incoming request type and return response accordingly in Django? Thanks in advance. -

How to build a Selenium Chrome extension and Django?

Preventing duplicate XMLHttpRequests in Django
In my app, clicking a button sends a XHR request to my server to upgrade an account and charge the user. def upgradeView(request): if request.user.upgraded == False: billAccount(request.user.id) else: return HttpRequests('Already billed') request.user.upgraded = True request.user.save() return HttpResponse('OK!') I can alter the button using Javascript so that it will be disabled after the user clicks it once. How can I confirm on the server side that the user can't submit 5 XHR requests simultaneously and end up getting billed 5 times? I have a manual check, checking whether they have already been billed, but what if the billAccount function takes a few seconds, and multiple requests are able to trigger the billAccount call before the user is able to be set as upgraded? The more I think about it, the more it seems impossible prevent multiple requests sliding in. Even if the billAccount call is a milisecond, that's still enough time for multiple requests to come in. -

Docker - make my application use secrets instead of env. vars
My Django application uses at lot of environment variables, around 35 in total. Currently all these are handeld by a .env file that I source before I start my application stack. I guess that I don't have to point out that this is by far a very insecure way especially if it's about secret key's in production ... Now my problem is that I don't really understand how to make the switch from a .env file to secrets, as I don't understand how to process the secrets at my container. For example, Django uses a connection string to connect with my MySQL database, see below: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'OPTIONS': { 'init_command': "SET sql_mode='STRICT_TRANS_TABLES'", }, 'NAME': env.str('MYSQL_DB'), 'USER': env.str('MYSQL_USER'), 'PASSWORD': env.str('MYSQL_PWD'), 'HOST': env.str('MYSQL_HOST'), 'PORT': env.str('MYSQL_PORT'), } } Most of the time I use "env.str" to fetch my vars that I pass to the container at start. So how can I make my Django application work with docker secrets and if possible stay with fetching vars the way like shown above? Is it maybe possible to load all needed vars on start at my docker-entrypoint.sh, and if yes, how can this be accomplished? I already came acorss this … -

django model optimization, fields applicable on two Models
I question myself on how to create my models well. I have Project Model which contains multiple Control (and each Control is applicable on multiple Project). But each Control got specific attributes for the Project I mean, a Project can have 10 Controls, and each control Applicable can be "Applicable" or "Not Applicable" Status can be "Not Planned", "Planned", "Done" So I made this : class Project(models.Model): name = models.CharField(max_length=100) code = models.PositiveSmallIntegerField("code", null=True, blank=True) description = models.TextField(default="") class Control(models.Model): control_description = models.TextField() and a third Model for the links between Project / Control / Others class ProjectControl(models.Model): APPLICABLE_CHOICES = ( ("A","Applicable"), ("NA","Not Applicable"), ) STATUS_CHOICES = ( ("D","Done"), ("NP", "Not Planned"), ("P", "Planned") ) project = models.ForeignKey('Project', verbose_name="Project", on_delete=models.CASCADE) control = models.ForeignKey('Control', verbose_name="Controle", on_delete=models.CASCADE) applicable = models.CharField(max_length=100, null=True, choices=APPLICABLE_CHOICES) status = models.CharField(max_length=100, choices=STATUS_CHOICES) Is there a better (or more conventional) way to do this ? I'm just facing an issue when using API, if I want all applicable controls of a project, I have to parse the whole ProjectControl Table, and I think, if the project goes big, performance issues.

I need to use a POST request instead of a GET request because the URI for the GET request is too long (I had to change nginx and gunicorn limits on the production server, to unlimited length (max wasn't enough) which opens the site up to ddos attacks, which is obviously not ideal.
