Django Rest Framework add page number attribute using the PageNumberPagination class
I am building an API in Django and I am trying to add the page number on the json results. And I am trying to add the page number in the returned results for example, I am currently getting this; { "links": { "next": null, "previous": null }, "count": 1, "results": [ { "url": "http://127.0.0.1:8000/api/brands/1/?format=json", "name": "microsoft", "description": "Nothing", "top_brand": true, "guid": "microsoft" } ] } But I am trying to get something like this; { "count": 1, "results": [ { "url": "http://127.0.0.1:8000/api/brands/1/?format=json", "name": "microsoft", "description": "Nothing", "top_brand": true, "guid": "microsoft" }, ... ], "page_number": 1, "from": 1, "to": 10, "last_page": 4 } The most important attribute is the page_number but I am not so sure how to get that from the parent class using self... I see no direct way besides using a function. Here is my code; class StandardResultsSetPagination(PageNumberPagination): page_size = 100 page_size_query_param = 'page_size' max_page_size = 1000 def get_paginated_response(self, data): return Response({ 'links': { 'next': self.get_next_link(), 'previous': self.get_previous_link() }, 'count': self.page.paginator.count, 'results': data, 'page_number': self.page.paginator.count, }) -
How to enable default error views in Django 1.11?
I upgraded a Django project to 1.11, and now some of the default error views don't work anymore. I have these settings: handler500 = 'myhandle_500' handler404 = 'myhandle_404' handler403 = django.views.defaults.permission_denied However, I've implemented a simple test view for the 403 error, which just raises a PermissionDenied exception, and while this used to show my custom 403.html template, now it's treated like a generic server exception and shows my 500.html template. How do I restore this functionality? -
How to run a python script inside javascript and refresh the view in django
I have a python script that takes in some data and manipulates it. However i need it to run on the client side inside the javascript to process some data and refresh the view. The python file that manipulates data works well as I have tested it inside the IDLE shell DataManipulation.py class ModifyData(object): #Bunch of functions to manipulate data below is the function used to render the view with url '.../test' which also works perfectly. views.py def test(request): template = 'app/test.html' file = 'documents/Sample.csv' #File to be loaded args = {'test': file } return render(request, template, args) After loading this page, i use a javascript library that displays the data on the page in a table, the user can then manipulate the data like multiply a column by 3, but where I am stuck is how to take my DataManipulation.py file to modify the data and updates the page with the updated column on a button click -

Jwt Decode using PyJWT raises Signature verification failed
I'm running into a weird issue with decoding the jwt token in the django views. If I try jwt.decode('encoded_token', 'secret') then I see the "Signature verification failed" message. In order to escape from this issue I've set the verify flag to False: jwt.decode('eroded_token', 'secret', verify=False) This gives the decoded payload with no error but I'm trying to figure out how I can verify the token successfully without setting the verify flag to False.

django collectstatic with settings flag throws logging path error using incorrect logging path
I've recently started restructuring a project to use two scoops style configuration, with a config package, with settings inside it. Within that package, there's _base.py, development.py, staging.py and production.py. Since this is deployed as a WSGI app with Apache, I'm using a json file for environment variables, such as AWS credentials, db username/passwords and such. In short, following suggestions listed at https://medium.com/@ayarshabeer/django-best-practice-settings-file-for-multiple-environments-6d71c6966ee2 When deploying on staging, I have the wsgi app running through apache. In addition, manage.py $COMMAND is working with the --settings=config.settings.staging flag set. That is, with the exception of collectstatic. It's apparently trying to access an invalid logging path, and I can't figure out why its using that particular path which is not defined in the settings file being used.

Problems with MongoDB and Python
Good evening guys, I need some help. I need to implement a MongoDB database as a default or secondary (if possible) in an application made in Django. Currently my Django application works with Tweepy, I need to save the captured data in the NoSQL database. I chose MongoDb, but I found several information saying that it is only possible to use with python 2.7 (my application was built in python 3.5). Is there any way to do it? I have already tried to use pymongo, mongodbengine, among others without success ... I believe that I am not doing correct. I need guidance in this process (I did not find information for newer versions of django and python, and the documentation has not been updated) -
