Trying to Publish a django app with a MySQL Database and a React front end to Heroku
I am trying to publish a django app with a MySQL database and a React front end to Heroku. It runs locally just fine, but I cannot get it to work on Heroku. My code is here: https://github.com/rmoscoe/odyssey, but there's not much of it yet. I'm just getting started. I'm able to push to Heroku, and the build and deployment complete with no errors. But when I visit the site, it just says "Bad Request (400)." The console similarly just says "Failed to load resource: the server responded with a status of 400 (Bad Request)." The logs don't say much more: "at=info method=GET path="/" host=odyssey-db3a471a3d45.herokuapp.com request_id=4f1b44ca-f023-4e72-b1be-d03f9dbde384 fwd="104.32.1.116" dyno=web.1 connect=0ms service=162ms status=400 bytes=428 protocol=https." I've scoured the internet and tried many different solutions, but nothing has made a difference. Some examples: manually running collectstatic before pushing using the heroku terminal to run npm install and npm start on the client side assorted changes to my Procfile and settings.py manually copying the contents of the static directory into the staticfiles directory Can anyone help me? Thanks! -

Django Tastypie - Inserting parent and child objects in a single atomic transaction
I am trying to implement REST API using PostgreSQL, Tastypie and Django. I managed to implement [GET] API endpoint, but I'm having troubles with implementing [POST] API operation. The cause of my troubles is the fact that I have a table "parent" which can have many child objects defined in Django. The definition of models is below: ` class Parent(models.Model): title = models.CharField(max_length=200, null=False, blank=False, unique=True) owner = models.ForeignKey(User, on_delete=models.SET_NULL, null=True, blank=True) is_private = models.BooleanField(null=False, blank=False, default=False) class Meta: db_table = 'test_parent' class Child(models.Model): title = models.CharField(max_length=200, null=False, blank=False) parent = models.ForeignKey(Parent, on_delete=models.CASCADE, null=False, blank=False, related_name='components') is_mandatory = models.BooleanField(null=False, blank=False, default=False) is_visible_in_table = models.BooleanField(null=False, blank=False, default=False) is_visible_in_form = models.BooleanField(null=False, blank=False, default=False) options = models.JSONField(null=True, blank=False) note = models.TextField(null=True, blank=True) class Meta: db_table = 'test_child' ` This is the definition of Tastypie resources: ` class ChildResource(ModelResource): parent = fields.ToOneField('app.api.resources.test.ParentResource', attribute='parent') class Meta: list_allowed_methods = ('get', 'post',) detail_allowed_methods = ('get', 'post', 'patch', 'delete',) authorization = AnonymousCanPostAuthorization() authentication = MultiAuthentication( ApiKeyAuthentication(), CookieBasicAuthentication(), Authentication(), ) resource_name = 'test/child' queryset = Child.objects.prefetch_related('component').filter(is_active=True) always_return_data = True filtering = { "id": ('exact',), "components": ALL_WITH_RELATIONS, } class ParentResource(ModelResource): owner = fields.ToOneField( UserResource, attribute='owner', full=True, null=True ) components = fields.ToManyField( ChildResource, attribute='components', full=True, null=True ) class Meta: resource_name = … -
Nginx with GZIP not compressing Django responses even when it is enabled
I have a Django project that runs via Nginx web server. I've enabled gzip settings on nginx.conf like this: gzip on; gzip_vary on; gzip_proxied any; gzip_comp_level 6; gzip_buffers 16 8k; gzip_http_version 1.1; gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript; gzip_min_length 256; Now I have nginx upstream like this: upstream example { keepalive 500; server 127.0.0.1:8001; } server { listen 0.0.0.0:80 server_name example.com } location / { proxy_pass http://ikhlas; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; } In Django, I have a method that returns JSON with 16MB of size when I enabled gzip it returned to me same JSON with 16MB of size while having Content-Encoding: gzip response header. Why it is not compressing Django responses even if gzip is enabled and returns Content-Encoding header? -
Annotating Many2Many link works but only on SQLite (testing) not MariaDB (Production)
I am trying to annotate a model that includes a many2many link: class Link(models.Model): products = models.ManyToManyField(Product, related_name = "%(class)s_name", related_query_name = "product_link_qs", blank = True) position = models.ForeignKey(Position, on_delete = models.CASCADE) class Position(models.Model): place_id = models.PositiveIntegerField(unique = True) store = models.ForeignKey(Store, on_delete = models.CASCADE) class Store(models.Model): name = models.CharField("name", max_length = 32) in my admin I used annotate() to couple the information: @admin.register(Link) class LinkAdmin(admin.ModelAdmin): list_display = ["product", "get_store"] list_filter = ["position__store"] ### extend by product_link_qs related name property to make field sortable in the admin def get_queryset(self, request): qs = super().get_queryset(request) return qs.annotate(storename = Product.objects.filter(product_link_qs = OuterRef("id")).values("store__name")) @admin.display(description = "store name", ordering = "storename") def get_store(self, obj): if obj.asset: return obj.device.store or None return obj.storename or None only one product is linked to a position: this works perfectly fine in SQLite on testing and MariaDB in production adding a second relation to a link: works on SQLite in testing, but gives: django.db.utils.OperationalError: (1242, 'Subquery returns more than 1 row') -
Krakend Multiple Authorization Methods
I have an application that exposes a few endpoints which, for backward compatibility purposes, support both JWT and Basic Authorization methods. Recently we have decided to use KrakenD as the API Gateway for this application, now I have an issue with the authorization of the mentioned endpoints. I use auth/validator plugin for JWT validation and it works fine. But I'm looking for a way to bypass it when it fails and proxy the request directly to the application to use Basic Auth on the application side. I had an idea about writing a plugin for KrakenD to decide whether the Authorization header is a Basic or Bearer and then decide what to do with the request, or else to see if the JWT validation has failed and then proxy the request to the backend. I wasn't able to do any of those, so I'm looking for new ideas or an already existing solution for this. -

Django three-step registration
Please tell me, I'm doing a 3-step registration, using 3 forms that inherit from ModelForm and view classes that inherit from FormView. The first two pages were ok. On the first, I write down the first name, last name, mail and number in the session. On the second, I confirm the mail using the code. But there is a problem with the third page. There should be two fields: Enter password Enter the password again. And here in the form I don’t know how to make the password validation be from Django (well, that is, checking for length, characters, similarity between the first and second input field, etc.). Tell me, please, how to do this? From what class to inherit in the form? FormView class registration_step3(FormView): form_class = RegistrationForm3 template_name = 'html/log_&_reg/registration_add_password.html' success_url = reverse_lazy('authorization') def dispatch(self, request, *args, **kwargs): if 'registration_data' not in self.request.session: return redirect(reverse_lazy('registration_step1')) return super().dispatch(request, *args, **kwargs) def form_valid(self, form): print("Форма прошла валидацию успешно.") registration_data = self.request.session.get('registration_data') print(registration_data) if registration_data: user = CustomUser.objects.create( first_name=registration_data['first_name'], last_name=registration_data['last_name'], email=registration_data['email'], phone_number=registration_data['phone_number'], notification_access=registration_data['notification_access'], email_verified=True, password=form.cleaned_data['password2'], ) del self.request.session['registration_data'] self.request.session.save() return super().form_valid(form) else: # Handle the case when registration_data is not found in the session return self.form_invalid(form) def form_invalid(self, form): print("Форма не … -

Django - Code between Declaration and Render not executing

I'm creating a simple web page with a form but the form content is not loading and after doing some digging i've discovered that any code between the function delaration request and the render is not being executed. @login_required(login_url='') def index(request): print('Hello World!') project = projectForm() return render(request, 'index.html', {'form': project}) so in the above example Hello World! and creation of the project form do not execute, but the page loads, albeit without any form content.

MariaDB table got non-consecutive primary key after running a Django application
We have been running a Django application for years, and the operation accumulated multiple thousands of historical transactions. We recently sampled through the real data and realized that the transaction table contains non-consecutive values in its primary key id column. The jumping primary keys widely exist in the data, and typically, a sample query for id with an interval of 1000 will only yield three hundred records. By reviewing the application's source code, we have the following details, not sure if relevant, though. The DDL has AUTO_INCREMENT on the id column, so we believe the database will automatically increment on this column. In the Python source code, the model Transaction does not contain the primary key id column, so this column is added by the Django framework. In the function writing the transaction to database, there is no mention of the primary key id column either. However, the function has @transaction.atomic, and we are not sure whether the notation has any influence on the system behavior. The technical stack is: MariaDB v10.5, Python v3.7, Django v3.1.4. Our Question: Why does the database have non-consecutive primary keys on the table? Is it common for applications to have non-consecutive primary keys in … -

Good afternoon, I need to rename the files that users upload through a form with the nomenclature (DSR_"rut"-"name"-"label name (from form)"-0-"extension"). The parts of the rut, the name and the extension I could already generate, but I don't know how to do the name of the label. example: if the label says "image": (DSR_"rut"-"name"-image-0-"extension").

django csrf gives forbidden 403 error for POST
I'm trying to learning Django and as part of a tutorial, i was trying to pass some data through forms. It was good with GET, but POST gives me a forbidden 403. I googled and applied many of those tricks but nothing helped. Here is my code: view @csrf_protect def counter(request): template = loader.get_template("counter.html") ss = request.POST["cnt"] context = { "words" : len(ss.split(" ")) } return HttpResponse(template.render(context, request)) form <form method="post" action="counter"> {% csrf_token %} <textarea name="cnt" rows="10" cols="50"></textarea><br> <input type="submit"> </form> The 403 error at first was: Forbidden (403) CSRF verification failed. Request aborted. Help Reason given for failure: CSRF token missing. But after removing cookies (I read that it might be an issue with the cookie), it changed to: Forbidden (403) CSRF verification failed. Request aborted.
