How to return to HTTP_REFERRER instead of passing a template to TemplateResponse?
I am writing an application that has a page with content ideas. User has the ability to schedule any post right from this page. The schedule button calls a view SocialPost that schedules a post and then redirects the user to the same page from where it came using return HttpResponseRedirect(request.META.get('HTTP_REFERER')). This works perfectly fine. However, I am also using a middleware and TemplateResponse hook to decrement the user-allocated quota. I understand that in order to make TemplateResponse hook to work I should return TemplateResponnse in the view instead of HttpResponseRedirect. The problem is that I don't have the html file path to pass in TemplateResponse. The equivalent I have been using is return TemplateResponse(request, request.META.get('HTTP_REFERER')). This is not working. Can you please guide how to redirect to the same page from user came using TempalteResponse. -
How to prevent a user from manually going to some specific urls?
In my app, I want the user to access one specific url when he has paid the money via paypal client-side integration. my paypal integration comes from here. Now at the end(of the given link) I have to redirect the user to another page, by doing this, onApprove: function(data, actions) { return actions.order.capture().then(function(details) { // Show a success message to the buyer alert('Transaction completed by ' + details.payer.name.given_name + '!'); window.location.href='/accepted/{{transaction_id}}'; }); Now at the accepted page, I have to do some serious tasks that includes inserting records to database about the whole transaction. If user pays the money and go to that page, it's fine. But if the user inspected the page(by pressing F12) and manually moved to that url, he wouldn't pay but the transaction will be stored on the database. How can i avoid this? Please guys, I have been stuck for a long time. Thank you:) -
How to refer a submit element after submiting the form?
I am trying to refer a submit element after submitting a form but it is not working. At first, a tab named London consists a form and after submitting the form the result is stored in Paris tab.

Django models to hold a list of objects from another Model
I am creating a shopping cart for an e-commerce platform. I have made a Products model and the I need to create a Cart model. One cart can have multiple products in it. I need to create a field products in the cart which is a list of multiple product objects. I am not sure how to do it but I can think of two ways:- Create a list of ids of all the products Create a list which contains the product objects inside of them (this might save lookup time) The product model looks like this:- class Product(models.Model): # Define the fields of the product model name = models.CharField(max_length=100) price = models.IntegerField(default=0) quantity = models.IntegerField(default=0) description = models.CharField(max_length=200, default='', null=True, blank=True) image = models.ImageField(upload_to='market/static/images/products') category = models.ForeignKey(Category, on_delete=models.CASCADE, default=1) # Foriegn key with Category Model store = models.ForeignKey(Store, on_delete=models.CASCADE, default=1) The foreignkey relation doesn't seem to work here because it only stores one entry at a time. I think ManytoManyFields might work but I am not able to connect it between these two models. -

How to enable the ltree extension on google cloud sql
First of al: ltree is a postgres plugin, which seems to be officially supported by google (see GCP PostgreSQL extensions) In the same documentation I read that you need to enable the extension first (like on a normal postgres database). My backend application is written in the django framework and I basically instruct it to run the following command, which works without hick ups on my local machine: CREATE EXTENSION IF NOT EXISTS ltree; However, when I run that migration, I get the following error: Traceback (most recent call last): File "/usr/local/lib/python3.7/site-packages/django/db/backends/utils.py", line 82, in _execute return self.cursor.execute(sql) psycopg2.errors.InsufficientPrivilege: permission denied to create extension "ltree" HINT: Must be superuser to create this extension. This makes sense since according to the documentation, "the postgres user must be part of the cloudsqlsuperuser role". However, I see no way to give my user that role. I tried the default postgres user, which according to the documentation page above should be configured correctly, but it basically does not work. When I dig deeper in the cloudsql documentation, I read something even more surprising: it does not seem to be possible to create superusers according to this documentation. So, the question is quite simple: How … -

Django extend base.html work on all pages but one
Today i tried to setup Django authentification on an app and it's working a 99%. The registration and login are working perfectly but i have a problem on the userprofile page. Registration, login and userprofile templates all have the extends base.html and it's working for the registration and login, but on the userprofile page i get an error saying that the source base.html can't be round. Strangest thing is that the path value that Django trie is the correct one, same as the other two templates. This is the structure of my templates folder : Templates Account Registration.html Login.html Userprofile.html Base Base.html Most of the post if have found about extend base error usualy incombe the extend not working at all or not working in one folder but working in the others where mine work for two templates out of 3 in the same folder. I tried to remove most of the code in my userprofile template to see if anything was messing with the extend but even there i get the same error. -

How to descrease SQL queries count generated by model method in Django?

How to save and run python function in HTML button?
Context: For a face recognition project, user should upload a selfie and that pic will be saved in a S3 bucket (AWS) so the final result will be a template with that selfie and the person who looks like you. So, I want a button that save the image uploaded by user and at the same time, run the face recognition function. template: <form method="post" enctype="multipart/form-data" id="upload-form" action="{% url 'erp:fibocal' %}"> <div class="card-footer"> <button type="submit" class="btn btn-primary btn-flat" onclick="showLoaderOnClick('{% url 'erp:fibocal' %}')"> <i class="fas fa-save"></i> ¡Encontrá tu parecido! </button> </div> </form> And that button don´t save the image in my s3 bucket, only runs "erp:fibocal" that is a function in views.py: def fibocal(request): if request.method == 'POST': img_loaded = request.FILES['image'] imagenes = FR(img_loaded) return render(request, 'base.html', {'name': imagenes[0], 'prct':imagenes[1]}) else: return render(request, 'home/register.html', {}) ``` I think that I should save the image at the "fibocal" function but I don´t know how.
