How to block requests from apps like postman, insomnia and allow only one origin - django rest framework
I try to block the possibility to send a post request to my app via postman or insomnia. I want to limit the source of a request to one domain www.sample.com. I did add this domain to the ALLOWED_HOSTS and CORS_ORIGIN_WHITELIST, and nothing more and still I can send a request and save the data in my django app. How can I limit the origin of a request to the one domain and block all others or return "Unauth msg"?

Translated URLs in Django that work simultaneously for all languages
Given a view defined by a function about_us, I would like it to be accessible by either one of these URLs: /about/ /acerca-de/ In a way that requesting any of those activates the corresponding language and renders the view, but both URLs remain accessible at all times regardless of the currently active language. I would also like to reverse these URLs inside templates using the path name, so reverse('about_us') can give me the URL that corresponds to the currently active language. Django offers a mechanism for translating URLs by wrapping the string matchers for path objects in gettext_lazy so reverse URL resolution can return the one appropriate for the current language, but AFAIK only one of the URLs works at any given time, depending on the current language. If I instead define two path objects then I can point them to the same view wrapped by some view decorator that activates the given language first, but then I lose the ability to perform reverse URL resolution and I am forced to perform some ugly tricks to get links to respect the current language. Has anyone found a solution to this problem? -

I want to create a 'bulletin' page where I filter a few models by start- and end- date. path('bulletin/<int:startyear>-<int:startmonth>-<int:startday>/<int:endyear>-<int:endmonth>-<int:endday>/', bulletin_view, name="bulletin"), And the view: def bulletin_view(request, startyear, startmonth, startday, endyear, endmonth, endday): start_date= startyear + '-' + startmonth + '-' + startday end_date= endyear + '-' + endmonth + '-' + endday dateEvents = dateEvent.objects.filter(start_date_time__gte=start_date).filter(start_date_time__lte=end_date).order_by('start_date_time') context = { 'dateEvents': dateEvents, } return redirect('bulletin') When I go to this URL: /bulletin/2020-06-01/2020-06-30/ I keep getting: TypeError at /bulletin/2020-06-01/2020-06-30/ bulletin_view() got an unexpected keyword argument 'startyear' I've changed parameters names, replaced '-' with '/', taken the 'int:' out; nothing, I still get the error.

Django annotations m2m duplication
I am trying to do an annotation with django, for some reason I am getting a weird result when I add the m2m of task: qs = qs.annotate(Sum('activitytime__cost'), Sum('tasks__tasktime__cost')) activitytime__cost = 600 ! WRONG ! When I do: qs = qs.annotate(Sum('activitytime__cost')) I get the correct value of 200, but it seems like it's multiplying by the amount of tasks I have when trying to sum the m2m of tasks. Any help is much appreciated. -
How to display extended user model extrafield at django-rest-auth registration endpoind
I am trying to use the django-rest-auth library on my django rest framework api. What I have done here, is extending my user model by using a one to one field to the basic user model, and adding an extra field role, which is going to be a choice between "Student" and "Teacher". Here is my model: from django.db import models from django.contrib.auth.models import User ROLES = [ ('Student', 'Student'), ('Teacher', 'Teacher'), ] class AxessUser(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) role = models.CharField(max_length=7, choices=ROLES, default="Student") The role field is displayed as an inline inside the admin site. In fact, the result is the following: So far so good. Now when I try to access the rest-auth endpoint for registration, obviously I am presented with a registration form for the generic django user model. So my question is, how do I implement this field inside the rest-auth registration endpoint? -

how to have an "add another file" feature in a django form?

(not selecting multiple files with a unique submit button) example of process : 1) select a file, click on upload, 2) display : the name of the uploaded file, a button to remove this file if needed a button to upload another file 3) eventually click on submit to save the Document and its multiple files. -

Sending attachment in django using SendGrid
I have an html string I convert to PDF using Weasyprint and thereafter attaching it to an email which is sent using SendGrid. The code below is working. But I have two question: Since I store the file to MEDIA_ROOT using Weasyprint, will the fail be saved and therefore has to be deleted after sending? Or is it only stored temporary?

Django template tags conditionals
Right, am struggling with my blog app when trying to render some logic through the template view. So the idea is to render a one time only button for the newly authenticated users that do not have a post published and after the user has published its first post the button will be rendered within a for loop so he/she'll be able to create/delete a new one from there. views.py @login_required(login_url='app_users:login') @allowed_users(allowed_roles=['admin', 'staff', 'users']) def blog(request): posts = BlogPost.objects.all().order_by('date_posted') context = {'title': 'Blog', 'posts': posts} return render(request, 'app_blog/blog.html', context) models.py class BlogPost(models.Model): title = models.CharField(max_length=100, null=True) content = models.TextField(null=True) date_posted = models.DateTimeField(default=timezone.now, null=True, blank=True) author = models.ForeignKey(User, on_delete=models.CASCADE) def __str__(self): return self.title blog.html {% block content %} {% if request.user not in posts|last %} <div class="container" style="float: left;"> <a class="btn btn-primary btn-sm mt-1 mb-1" href="{% url 'app_blog:blog_create' user.id %}"><h5>C'mon {{ request.user.username }}, don't be shy! Create Your First Blog Post!</h5></a> </div> {% endif %} <br> <br> {% for post in posts %} <br> <div class="container"> <article class="media content-section"> <img class="rounded-circle account-img" src="{{ post.author.profile.image.url }}" alt="Image could not be uploaded!"> <div class="card-body media-body"> <div class="article-metadata"> <a class="mr-2" href="{% url 'app_blog:blog_user_detail' post.id %}">{{ post.author }}</a> <small class="text-muted">{{ post.date_posted|date:"d F Y" }}</small> </div> …
