Django: How to transfer a html table from a template to a database table?
I have a html template (review.html) which get populated dynamically with a html table. The table data can be changed by the user. After the user has made his changes, he than can save the whole table data to a django database table by clicking a submit button. Here is the part where I need help: How can I insert the html table data into the database table? The database table exists and all migrations are done. The html table has the same columns and column names as the database table, the datatypes are also the same. I just don't know how to write the function for the POST-request for the button click event. -
How exactly do we implement swagger docs for django APIView
So I have a django GenericAPIView Endpoint, for which I want to add swagger documentation. I have searched all over the documentation on how to do the django-rest-swagger, but I can't seem to understand them very much. Below are my files. views.py class SignUpAPIView(GenericAPIView): """ get: Not Available post: This endpoint presents Sign Up facility for the user. Try it urself by sending a request in the below form """ permission_classes = [AllowAny] serializer_class = SignupSerializer def get(self, request, format=None): return Response("Only POST Method is allowed") def post(self,request,format=None): serializer = SignupSerializer(data=request.data) data = request.data if serializer.is_valid(): valid_data=serializer.data print(valid_data) return Response("Success", status=status.HTTP_200_OK) serializer.py class SignupSerializer(serializers.Serializer): name = serializers.CharField(required=True, max_length=150) username = serializers.CharField(required=True, max_length=150) mobileNumber = serializers.CharField(required=True, max_length=10) email = serializers.CharField(required=True, max_length=150) password = serializers.CharField(required=True, max_length=150) This is the current Swagger Doc UI, that is being rendered. How do I make the example value in the Description to something of the below form? { "user":{ "name":"string", "username":"string", "mobileNumber":"string", "email":"string", "password":"string" } } Also, If someone could explain how exactly we can create good documentation using swagger, it would be of great help. A brief explanation of how exactly swagger works would be helpful. Thanks in advance. -

How can I use Django's translation strings with Wagtailtrans (Add-on for supporting multi language Wagtail sites)
So I have a website which is using the Wagtailtrans extension for Wagtail. I basically enables multi language by duplicating the page tree. So the url gets fixed with the language-code at the start. I can translate all my content which I define through my models perfectly fine. Here's an example of how that works: class ServicesPage(MetadataPageMixin, TranslatablePage): description = models.CharField(max_length=255, blank=True,) content_panels = Page.content_panels + [ FieldPanel('description', classname="full") ] Instead of Page you define it as TranslatablePage in your model. All is working fine, however I still need some additional strings which I don't define in my models to be translated. I just use Django's translation feature with {% load i18n %} and then the strings wrapped inside {% trans "String" %}. So far so good, I defined my two languages in Wagtail admin (Wagtail trans creates an option for that) which in this case is English and Dutch. I set English as the main language so the strings are in english. I use ./manage.py makemessages and it creates a .po file for me, with all the tagged strings in there. At last I use ./manage.py compilemessages. But translated strings are not showing up when I switch to Dutch … -
How can I communicate with external python script from Django server
I have a Django server running in my pc and a client browser running into a Raspberry Pi. The Raspberry Pi has a RFID-RC522 reader which may read nfc tags. My idea is to write a python script on the client side (RPi) that detect when a RFID card is read and send the read rfid id to the Django Server in order to login a user. Mi question is, How can I communicate with the server using this external python script? Im using this SimpleMFRC522 Library to read from rfid reader. The desired workflow is: A user access to the WebApp using a local IP ("192.168.0.105:8000"). Django server respond serving the login page. The user wants to login with the RFID card, and bring the card to the reader. The reader, running in a external python, send the id of the card to Django Server. Django server autenticate the user. -

"Were sorry but something went wrong" while trying to access Django application on A2
I have been working on deploying a somewhat existing django application on an A2 shared server. I have been following the following guides: https://medium.com/@isaactchikutukutu/deploying-django2-python3-on-a2-hosting-9e786a3e38ad https://www.a2hosting.co.uk/kb/developer-corner/python/installing-and-configuring-django-on-unmanaged-servers Any time I try to visit my website all I get is a page that says "We're sorry, but something went wrong" It gives me an error ID and says Web application could not be started by the Phusion Passenger application server. Please read the Passenger log file (search for the Error ID) to find the details of the error. I'm not sure where to find the Passenger log files and thus I have no idea how to figure out what isn't working properly. When I run manage.py it seems to run fine. I can call run server and it works fine. It would be awesome if someone could help me move forward with this. Thanks! -
Converted whole pyshipping project from python 2 to 3 by using the in-built python tool 2to3 but it does not work in python 3
Pyhton newbie here, very good chance I am doing a silly mistake here.. After losing a good amount of hair and searching for many hours, I am still not able to convert a whole project to python 3. I have a project made in django framework and it uses python 3.7, and I wanted to incorporate this library into my app. But, because pyshipping uses python 2.7, I thought it may cause compatibility issues. Following this answer,I converted the whole project and tried running this file binpack_simple.py. But it gives me an error I am not able to understand at all.

How to display in progress bar the progress of ajax request in Python and Jquery

django access related model status in custom managers
