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; … -
Why is Django not pulling from session? Also .get funtion no longer lights up as the .all function does? Nothing displays from database
`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. -
Django - complex annotation/aggregation based on date difference
I have models Category, Lead and Event. The event describes an action of generating leads (downloaded from external source) and can be created anytime - eg 2 times a day, then 7 days nothing, then 1 time a day etc. Event has a new_leads field that keeps track of Lead objects. Each Lead has some category (like clothes, electro etc). I'm trying to predict (based on the history) how many leads would be generated if I created a new event today. I started with annotating Event queryset by the counts of leads for each category. categories = Category.DEFAULT_CATEGORIES annotations = {category[0]:Count('new_leads',filter=Q(new_leads__category__name=category[1])) for category in categories} events = Event.objects.all().annotate(**annotations) Now, for every event, I can just call the category attribute this way: event.clothes which returns a number of new clothes. This is where I don't know how to continue. I want to calculate/annotate the average new leads count per day. Eg. for a particular event and category, I'll divide the number of leads by a number of days since the Event before. Something like event.clothes_avg_per_day and then I'd aggregate the average from all the events for all the categories. That way I'd have an average number of new leads per category … -

Exclude object from queryset if any of it's many to many related objects has a given property value
let's say I have a models like this: class Bar(Model): value = IntegerField() class Foo(Model): bars = ManyToManyField(Bar) Now, how do I get a queryset of Foo objects, excluding the ones, which have any of bars object with value of 0? Corresponding Python code would be like this: foos_ids_to_exclude = [] for foo in Foo.objects.all(): for bar in foo.bars.all(): if bar.value == 0: foos_ids_to_exclude.append(foo.id) break resulting_queryset = Foo.objects.exclude(id__in=foos_ids_to_exclude) But how do I do this on DjangoORM level?
