Update db after successful payment - DRF
In my project I use Django as my backend, vue as my frontend and stripe as my payment processing software. The users of my program will be able to buy in game currency (points). So whenever I recieve the checkout.session.completed webhook event I essentially want to change the users' points accordingly in the db. I thought of making an internal api request, through django, that updates the users' points but I quickly found out that it would be bad practice and should only be done when testing. I was just wondering how you would tackle this problem and what you think would be the best practice in this situation. If you need any more information, just ask. Thanks in advance. -

Displaying user uploaded image in Python Django
I am creating a website using the Django python framework and am currently stuck on a problem. I am using function views to display a page called myaccount, and on 'myaccount' i would like all user details to be displayed using context objects, for this page it is 'user'. I also have another model called Profile, which holds the profile picture and date of birth of the user. However when i attempt to display the image which has been uploaded during the account creation into the media folder named '/media/%y/%m/%d/imagename.filextension' i receive an error saying "The 'profilepicture' attribute has no file associated with it." I have been searching vastly for fixes to this issue and have so far found no result which has worked, i have tried to create a property function which gets the url from the image called 'get_absolute_url' by doing user.profile.profilepicture.get_absolute_url but it fails to work and displays the same error. I was wondering if anyone could point me in the direction of a fix for this or a solution. The code to display the image, views.py and urls.py is down below views.py @login_required def myaccount(request): return render(request, 'account/myaccount.html', {'section': 'myaccount'}) urls.py path('', views.myaccount, name='myaccount'), myaccount.html <img … -
How to call post_save signal after adding object to ManyToMany field on another model

Is there any way to organize filelds in django models?
I have many tables in my django models, each responsible for a different form in my template. I wrote some code to convert this fields directly into tempalte using python and JavaScript. Next I've been trying to add sections into template, which means that in my template each section has own title and own fields. After a few tries my code looked like an example: #before class forms_n(Models.Model): field1 = models.IntegerField() field2 = models.ForeignKey(ForeignModel, on_delete=models.CASCADE,null=False,blank=False) field3 = models.IntegerField() field4 = models.IntegerField() #after class form_n_cfg: @section_decorator(section=0,title="This is seciton 0") class form_n_0(models.Model): field1 = models.IntegerField() field2 = models.ForeignKey(ForeignModel, on_delete=models.CASCADE,null=False,blank=False) class Meta: abstract = True @section_decorator(section=1,title="This is seciton 1") class form_n_1(models.Model): field3 = models.IntegerField() field4 = models.IntegerField() class Meta: abstract = True class form_n(forms_n_cfg.form_n_0,forms_n_cfg,form_n_1): pass #utils.py def section_decorator(**kwargs): def set_attrs(obj): fields = obj._meta.fields for i in fields: for key,value in kwargs.items(): setattr(getattr(obj,i.name),key,value) return obj return set_attrs Everything worked fine, in time I realized that Foreignkey unlike other fields doesn't have any values from my decorator. I think the problem is because i added attrs to for parent class, not subclass form_n which i use (just why other fields had values from decorator). I noticed that just classes inner form_n_cfg has @section_decorator attributes for … -
