Am creating a settings page where the user should be able to chang there image and biodata. But only the biodata gets updated when I print the request.FILES.GET("profile_picture") it prints the name of the photo I uploaded. why is it not uploaded and saved to the database?

Django and DataTables ignoring Read, Edit, Delete buttons after initial 10 results
I am using Django with DataTables and it is working fine, except for one part I have not been able to figure out what I am missing. I have a table that adds Actions to each row READ, UPDATE and DELETE buttons to perform CRUD actions on each row of data. The buttons depend on data-form-url being set to the url and id, like the below, which then pop up in a modal. <button type="button" id="read-file" class="inline-block bs-modal btn btn-sm btn-primary" data-form-url="{% url 'read_file' fileupload.id %}"> <span class="fa fa-eye"></span> </button> This only works for the first 10 entries initialized in the table. The buttons are dead for entries 11 and beyond, basically anything not initialized in the first view and paginated or hidden via the "show 10, 25, 50, 100 entries" dropdown. Can someone help me understand why the buttons are not working and how to activate them again for paginated or hidden rows? views.py class FileUploadListView(generic.ListView): model = FileUpload context_object_name = 'fileuploads' template_name = 'fileupload/file-list-view.html' #Filter view for current user def get_queryset(self): """Returns FileUploads that belong to the current user""" return FileUpload.objects.filter(my_user=self.request.user) html (for the file-table which is included into a base file) <table class="table table-striped table-sm table-bordered {% … -
Bootstrap 4, Card Style in HTML
I use bootstrap 4 cards to develop my blog which actually looks grate, however, when it is used on a mobile version, the picture of the posts shifts on the top and all the dimensions go random.

How to import whole python file and not break F403 flake8 rule?
Imports like this: from .file import * are "anti-patterns". How can I import one python file into another, without breaking flake8 F430 rule? I have settings.py in the Django project that I want to "overwrite" in test_settings.py like this, from settings import * # make tests faster DATABASES['default'] = {'ENGINE': 'django.db.backends.sqlite3'} to test with in-memory database, and I cant figure out how to do it without breaking the rule. -
When doing runserver, keep getting new data loaded in my database
Every time I do a: python manage.py runserver And I load the site, python gets data and puts this in my database. Even when I already filled some info in the database. Enough to get a view of what I am working on. Now it is not loading the information I want and instead putting in new information to add to the database so it can work with some data. What is the reason my data in the database is not being processed? And how do I stop new data being loaded into the database. -

Stripe Checkout Webhook CSRF Error despite @csrf_exempt (Django)
I am using Stripe Checkout for my Django subscriptions. I tested webhooks via CLI locally - with success. Now I am moving the project to staging area and got a CSRF issue. The registered webhook throughs this message (my comments are already added): In general, this can occur when there is a genuine Cross Site Request Forgery, or when https://docs.djangoproject.com/en/2.2/ref/csrf/ Django's CSRF mechanism has not been used correctly. For POST forms, you need to ensure: Your browser is accepting cookies. -> Yes, all cookies are accepted. Tests with different browsers led to the same result. The view function passes a request to the template's https://docs.djangoproject.com/en/dev/topics/templates/#django.template.backends.base.Template.render “render” method. -> No template is being used, since Stripe Checkout provides the template. In the template, there is a “{% csrf_token %}” template tag inside each POST form that targets an internal URL. -> No, CSRF_TOKENS inside the html. No template is being used, since Stripe Checkout provides the template. If you are not using “CsrfViewMiddleware”, then you must use “csrf_protect” on any views that use the “csrf_token” template tag, as well as those that accept the POST data. -> I am using CsrfViewMiddleware. Funny fact: If I disable CsrfViewMiddleware, then webhooks are functioning. … -

Reverse for url with arguments '('',)' not found, but only on a certain machine
I deployed using Gunicorn and Nginx, and am seeing this error in one machine that's using my app, but not in the rest, so I'm starting to think it is an issue on the machine the error is displaying but not in the app. When doing the exact same actions to replicate the error in other machines, the app works just fine. The template form that causes the error: <form action="{% url 'cart:cart_add' product.id %}" method="post"> {% csrf_token %} <div class="form-group"> <label for="id_quantity"></label> <input data-toggle="touchspin" type="number" value="1" required id="id_quantity" name="quantity" data-bts-button-down-class="btn btn-danger" data-bts-button-up-class="btn btn-primary"> <input type="hidden" name="override" value="False" id="id_override"> </div> <button type="submit" class="btn btn-secondary"> <i class="uil-plus-circle"></i> Add to order </button> </form> urls.py: from django.urls import path from . import views app_name = 'cart' urlpatterns = [ path('', views.cart_detail, name='cart_detail'), path('add/<int:product_id>', views.cart_add, name='cart_add'), path('remove/<int:product_id>', views.cart_remove, name='cart_remove'), path('clear/', views.cart_clear, name='cart_clear'), ] Again, in other machines it is working just fine. -
Filtering on related fields in Django
I have two models in my Django project: ModelA(models.Model): name = models.CharField(max_length=20) ModelB(models.Model): a = models.ForeignKey(A, on_delete=models.CASCADE) date = models.DateField() There is a one-to-many relationship between models A and B, with around 50 instances of model A and 100,000 entries for model B. In the problem that I'm having, I have a specific queryset of ModelB, and from this queryset I want to know, for each date, how are these ModelB's distributed among the different ModelA. The data structure that I require is as follows: [ { "date": date_1, "num": num_1, "bins": [ { "name_A": model_A_1, "num": num_A_1_1 }, { "name_A": model_A_2, "num": num_A_1_2 } ] }, { "date": date_2, "num": num_2, "bins": [ { "name_A": model_A_1, "num": num_A_2_1 }, { "name_A": model_A_2, "num": num_A_2_2 } ] } ] where date_1 is one of the existing dates in Table B, num_1 is the total number of ModelB with date date_1. bins contains the distribution of ModelB among the different ModelA's, e.g. num_A_1_1 corresponds to the number of ModelB with date date_1 and Foreign key model_A_1, etc. Here's what I have tried: date_bins = initial_modelB_queryset.values("date").order_by("date").distinct() output = [] for bin in date_bins: B_A_queryset = ModelA.objects.filter(modelB__in=initial_modelB_queryset, modelB__date=bin["date"]) B_num = B_A_queryset.count() bins = … -

Previewing images using Django
I have a html,css and js app that I ported to Django and I want to preview an image before upload. A dropdown form allows users to select an option that will then display the image onto the screen before upload. I did this through javascript by setting img src = "" to empty and then when the user selected an option from the dropdown menu, javascript set the img src path i.e if user selected car from menu then js would set img src=images/car.png and display it. function displayImage(imgValue){ if (imgValue == 'car') { previewImage.setAttribute("src", "images/car.png"); previewDefaultText.style.display = "none"; previewImage.style.display = "block"; } else if (imgValue == 'location') { previewImage.setAttribute("src", "images/newyork.jpg"); previewDefaultText.style.display = "none"; previewImage.style.display = "block"; .... .... } The issue is that the JS isn't setting the path of the img src in Django. Can I do this through JS or will it require to rewrite in a more Django/pythonic way? Note: w/o the use of ajax. -
Convert multiple texts with python markdown in django views
