Possible source of cascade deletion on Django 1.9 project?
I'm working on a Django 1.9 project with a huge source and lots of is inherited from previous developers. When I delete a User object from the shell there are many other related objects that get deleted as well. I get a print output with a Tuple containing: (# of deleted objects, {u'CLASS_NAME': #number of deleted objects...}) I've searched all the code throughly and there are no Signals attached to User pre_ post_ or on_ delete, neither I can find where this print output is constructed... so, I have no idea where this is coming from. Any ideas for other possible ways this can be happening? -

Can I return a different Django Response based on whether or not the view is invoked from swagger?
I am using Django-Rest-Framework for my API. And I am documenting that API w/ swagger using drf_yasg. One of my views returns a Django FileResponse. When I access the view directly at "http://localhost:8000/api/my_documents/1" it successfully displays the (PDF) file. But when I access it via swagger it successfully returns a 200 but gives the following message: Unrecognized response type; displaying content as text. This is b/c of this issue in swagger itself. As suggested in that ticket, the problem goes away if I change the "Content-Disposition" response header from "inline" to "attachment". However, I don't want to always download the file. My question is: Can I determine whether the request was made by swagger in the view and conditionally change the headers? Something like: class MyDocumentView(GenericAPIVIew): def get(self, request, pk): my_document = MyDocument.objects.get(pk=pk) response = FileResponse(my_document.file) # (file is a FileField) # WHAT DO I PUT HERE ?!? if request.is_from_swagger: response.headers["Content-Disposition"] = response.headers["Content-Disposition"].replace("inline", "attachment") return response Thanks. -
Why does Django require change permission to add a foreign key?
I have two models in my application, Product and Holder. A Holder can have n products, and a Product must have one Holder. These are the classes: class Product: title = models.CharField(verbose_name=_('Title'), max_length=100) holder = models.ForeignKey(verbose_name=_('Main Holder'), to=Holder, on_delete=models.PROTECT) ... class Holder: name = models.CharField(verbose_name=_('Name'), max_length=50, unique=True) ... When a user that is a staff_member tries to create or change a Product, that specific user has to have the database's change_holder permission assigned to them, otherwise they can't assign a Holder to that Product. The list of holders won't even load up on the respective field on Admin, as the following image illustrates. Anyway, what I'd like to know is what justifies this behavior. Why would a user need permission to change the foreign key model, if they're not changing that model, but the one that contains the key? -

CSRF exempt for contactform - Django
Is it safe to use a CSRF exempt for a contactform or a form using the send_mail function from Django? So according to the docs; The first defense against CSRF attacks is to ensure that GET requests (and other ‘safe’ methods, as defined by RFC 7231#section-4.2.1) are side effect free. Is a POST request, which only creates an email message and does not touch the database, considered as a "safe" method? Example code from django.core.mail import BadHeaderError, send_mail from django.http import HttpResponse, HttpResponseRedirect def send_email(request): subject = request.POST.get('subject', '') message = request.POST.get('message', '') from_email = request.POST.get('from_email', '') if subject and message and from_email: try: send_mail(subject, message, from_email, ['admin@example.com']) except BadHeaderError: return HttpResponse('Invalid header found.') return HttpResponseRedirect('/contact/thanks/') else: # In reality we'd use a form class # to get proper validation errors. return HttpResponse('Make sure all fields are entered and valid.') *example from docs I'm just wondering if I'm not missing something before I add the CSRF exempt. Now I hear you thinking, why would someone want to disable the CSRF validation? In the EU we have to comply to the GDPR. By setting a cookie, we need to explicitly ask the user to accept cookies, if we can prevent setting … -

Save image from Django to S3 AWS without admin.py
I'm in a face recognition project and I would like that the final result show the image that the person upload (His/Her face) and the image of a person that you look a like. I want to store the uploaded image by some user to my S3 AWS bucket but I'm not using the admin.py script because I created a new template: where you upload your pic and then the "Ir" button runs a python function called "fibocal". template.html <div class="container-contact100-form-btn" id = "hola"> <ul><button type="submit" class="notify-btn" onclick="showLoaderOnClick('{% url 'gallery:fibocal' %}')"> <span> Ir </span> </button></ul> </div> and the "fibocal" function is 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], 'imagen': imagenes[2]}) else: return render(request, 'home/register.html', {}) So, I would like that when the user upload the image it will be save to the S3 budget, but I don´t know how to add the "Save" button that is in the default admin template by default. I would like to add a new function to "Ir" button that save the image at the S3 AWS and also runs the fibocal function. Thanks! -
How to make reverse foregnkey/1to1/MtoM connections explicit in django models?
Say there are two models like these: class Post(models.Model): ... class User(models.Model): posts = ManyToManyField(post, ...) ... I know that Post.user is still available in the django querysets and I know about relatedname but there are cases where I also need to add field users to Post model, to which, if I remember correcly, django issues a warning. In my case, I need to write a serializer (project uses DRF) for such implicit field, which is not possible (because "model Post doesn't have field users" to continue the example). And even if it's ok to ignore warning and just make fields explicit, situation is still hard since MtoM is an reverse of MtoM and 1to1 is a reverse of 1to1 but there is no reverse to foreignKey. -
how can restrict access to media image url
how can restrict access to media image url , and make it accessible only by access owner user in django , here is my class model : class private_image(models.Model): i_user = models.OneToOneField(User, related_name='related_PRF_user', on_delete=models.CASCADE) i_image= models.ImageField(upload_to='images', blank=True, null=True ) and my media settings is : MEDIA_ROOT = os.path.join(BASE_DIR, 'media_root/') MEDIA_URL = '/media_url/' i believe, i can make a small function to check access-user and requested URL '/media_url/images/' to get image name , and then get an object from database using image name and then check the owner(i_user) if same access-user . but how can i tell Django to use this function before service MEDIA_URL requests . if you have an example , that will be very helpful . thank you in advanced -
Django and Vuetify
Good morning, good afternoon or good night. How are you? I'm implementing an application using the famous and our Python friend Django and inside it I'm using Vuetify with our VueJs. I always used this using and creating APIs in Django and consuming it on Vuetify. However, I was given the challenge of using Vuetify inside Django using its CDN, but I have a lot of difficulties and I wanted to know if anyone here on the stack has been there. (In case of doubt, not that of npm install inside the django project, but just consume and call the components .Vue like this using your cdn too) In the base.html of django I was able to redenrize a vue page <!DOCTYPE html> {% load static %} <!--{% url 'social:begin' 'google-oauth2' as url_login_gmail %}--> <html lang="pt-br"> <head> <meta charset="UTF-8"> <title>Odontotolgia Undb</title> <link rel="shortcut icon" href="https://www.undb.edu.br/hubfs/avatar_site.png"> <link href="https://fonts.googleapis.com/css?family=Roboto:100,300,400,500,700,900" rel="stylesheet"> <link href="https://fonts.googleapis.com/css?family=Material+Icons" rel="stylesheet"> <link href="https://cdn.jsdelivr.net/npm/vuetify@2.x/dist/vuetify.min.css" rel="stylesheet"> <link href="https://cdn.jsdelivr.net/npm/@mdi/font@4.x/css/materialdesignicons.min.css" rel="stylesheet"> <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no, minimal-ui"> <style type="text/css"> a{ color: #fff; text-decoration: none; text-decoration-line: none; text-decoration-style: initial; text-decoration-color: initial; } </style> </head> <body> <div id="app"> <v-card height="665px" > <v-navigation-drawer v-model="drawer" :mini-variant.sync="mini" permanent absolute > <v-list-item class="px-4"> <v-list-item-avatar> <v-img src="https://randomuser.me/api/portraits/men/85.jpg"></v-img> </v-list-item-avatar> <v-list-item-title> &nbsp; … -

`from django.shortcuts import render,redirect, HttpResponse` `from user_login_app.models import User` `from .models import Book,Author,Rating` `from django.contrib import messages` def index(request): `user=User.objects.get(id=request.session['user_id'])`===================================================On this line the get function isn't operating I can no longer pull from session and the function doesn't light up the way it did. I also get no user display on the page. Normally the .get function highlights as the .all function does, also displays the logged in user on the page. No I get nothing from Session. To be clear, I also made all migrations. I have items in my database. I just can't pull them out. As I have in the past. `author=Author.objects.all()` `rating=Rating.objects.all()`My context statment no longer renders anything. I double checked it agianst past projects. those were all written very similarly. `context={` `'users':user,` `' authors':author,` `'ratings':rating,` } return render(request,'book_home.html',context) I don't get why my .get function doesn't work?? I hope someone has an answer to this puzzle.
