How to get objects like Bolean Field options? DJANGO
thanks for your time. By creating an object(product) i'd like to get the option to choose in a list of all my other objects (5 of them) to appear bellow the product. Like a recommended list. Although they don't have a field or category in common. I'd like to let the user of my software set the five of them manually to display for his client. is there something like: class Product (models.Model): name = models.CharField(max_length=100) related_products = models.CharField(choices=Product.objects.all()) or something like: def get_queryset (self): return Product.objects.all() class Product (models.Model): name = models.CharField(max_length=100) for p in queryset related_products = models.CharField(choices=Product.objects()) or like: class Product (models.Model): name = models.CharField(max_length=100) class Related_product (models.Model): product = models.ForeignKey(Product) -

Django serialize for specific id
I am using the serialize method to get a json of a Model object. However it does not work when I pass in a specific id. data = serialize('json', Sample.objects.get(id=1), use_natural_foreign_keys=True) print(data) It seems to only work when you get the entire model's content by all() i.e.: data = serialize('json', Sample.objects.all(), use_natural_foreign_keys=True) -
function should call after several hours with some parameters
I have a configuration like this Employee -> Manager Employee submits a transaction, it goes to the manager and the manager verifies it. I want to add a new configuration. Auto-action after some time(5-6 hours). If the manager is not taking action(verifying it) on Transaction, it will be auto-action according to my configuration. I can use SQS but it gives me only max 2hrs delay to process any function. Now I am thinking about using Redis, pushing an entry to Redis for some time according to config after it expires I will evaluate my function(auto-verify). Multiple employees can submit any number of Transactions for each Transaction I have to push a task to the queue and after each time it should call my function and dequeue from the queue. For Example: 1) Transaction1 is submitted on 6am and this employee has config of 4hrs then at 10am it should auto verify. -

POST IS SEARCHED FOR USERS IN USER DATABASE AND TURNED INTO PROFILE LINK WITH ORIGINAL TEXT
Hey guys I'm new to Django and trying to get a certain thing to work so sorry if I have made previous posts but I'm making great progess. What I'm trying to do is when a user submits a post to the database it's scanned to see if a user is mentioned in it so that when it renders as html it turns that user mentioned in the post into a url link for that users profile along with the original text. So the post is the same just if a user is mentioned it's the users name as a link to his or her profile in the original text. This is what's rendering right now when a post is submitted. post that is submitted by user as you can see @devil is a user and it's username with link appears above it but not in the post data. How would I go about doing it so that the post is checked for a user in the database if it as the symbol "@" in front of it and returns the username as a link to it's profile. This is views.py code for the post submission as you can see … -
Form not displaying on Django site
I have just started learning Django and I have hit a little snag and was hoping someone could help. Problem: My form is not displaying in my main HTML template (ingredior.html) but the form will display in my test HTML template (test.html) which is just a boiler plate HTML file with the {{form1}} tag in the body. I am changing "return render(request, 'ingredior/ingredior.html', context)" in the views.py file manually to test the two different HTML templates. Question: Why is the form working in the test.html and not the ingredior.html file when changed? Please keep in mind that I am swapping this line of code "return render(request, 'ingredior/ingredior.html', context)" with "return render(request, 'ingredior/test.html', context)" to test between the two.

Custom permission not passing to generic views django rest
I am writing custom permission and inheriting in the generic views but it is not working it returns TypeError: Cannot cast AnonymousUser to int. Are you trying to use it in place of User? instead of User required to perform this action my custom permission as follow class IsOwnedByUser(permissions.BasePermission): def has_object_permission(self, request, view, obj): message = {'detail': 'User required to perform this action'} return obj.user == request.user views.py class OrderAddressView(generics.ListCreateAPIView): queryset = OrderAddress.objects.all() serializer_class = OrderAddressSerializer permission_classes = (IsOwnedByUser,) def perform_create(self, serializer): serializer.save(user=self.request.user) def get_queryset(self): return OrderAddress.objects.filter(user=self.request.user) BTW, it works fine with default rest framework permission class when I use like this permission_class = (permissions.IsAuthenticated,) but with my custom permission it is not working( Can anyone tell why it is that?

How to create a downloadable URL for a zip file in Django?
I am trying to create a webpage that has a table where one of the columns in that table downloads a particular file that resides in my computer. The file that is supposed to be download is based on the ID number of that row.(ID is a column in my table) Ex. If the user clicks on the URL that is in the 3rd row then the file named '3.zip' in my local files should get downloaded. I have tried the <a href="<path>" download> in my HTML template file but I realized in Django the method is different. Then I used the HTTPResponse as an attachment method. This is my Views.py code for download. def download_file(request): fl_path = '/home/harish/Desktop/cvision/users_output_files/5/5.zip' filename = '5.zip' with open(fl_path, 'r') as zip_file: response = HttpResponse(zip_file, content_type='application/force-download') response['Content-Disposition'] = 'attachment; filename="%s"'%filename return response Urls.py urlpatterns = [ path('',views.homepage), path('add',views.datapage), path('newdata',views.newdata), path('newuser',views.newuser), path('download_file/',views.download_file) ] So, When I go to path http://127.0.0.1:8000/download_file the file is supposed to get downloaded. But instead I get an error. 'utf-8' codec can't decode byte 0xeb in position 10: invalid continuation byte If we ignore the Encoding error how can I solve the problem of downloading a particular file from local folders based … -
Django: UserCreationForm not getting Custom User Class
I'm new to django and I;m running into an odd issue. Using django 2.2.5 I've created a custom User class, sub-classed from AbstractBaseUser. Other than extending AbstractBaseUser the only major change I made was deleting the username field and adding my own (won't get into why here). I've added the USERNAME_FIELD = "my new username" to the model as well. This all appeared to work well and I was able to create users. I then installed django-registration, to use that functionality and when I tried to makemigrations I ran into this error: 'django.core.exceptions.FieldError: Unknown field(s) ("My new username") specified for User` Now this didn't make any sense to me since the model clearly has a"My new username" field and I'd specified django should use my User model in setting via AUTH_USER_MODEL. I knew that was working because calling get_user_model() in a shell returned my custom model. Now here's where it gets weird, I was able to trace the issue to django-registrations, RegistrationForm. This is a from that subclasses django's UserCreationForm. When RgistrationForm was loading or whatever during makemigrations it was producing the error because the model reference for the form was django.User not my custom user model. RegistrationForm does not … -

Django + Apache + Mobile Initiating Download Instead of Serving Page
