Need to return the object from the celery shared task queue process
I have faced the error "kombu.exceptions.EncodeError: Object of type 'JsonResponse' is not JSON serializable " In my settings.py : CELERY_BROKER_URL = 'amqp://localhost' CELERY_ACCEPT_CONTENT = ['application/json'] CELERY_RESULT_SERIALIZER = 'json' CELERY_TASK_SERIALIZER = 'json' CELERY_RESULT_BACKEND = 'django-db' So it only accepts response as a json value. But i need to return the object or instance Example : I need to return file path. Thanks in advance. @shared_task def celery_upload(path, id , user_id): upload = Upload() result = upload.file_generation_validation(path, id , user_id) excel = Excel() file_path = excel.Export(result["error"], "aaa") return file_path if I return result it will be successful, But file_path object throws error. -

Dynamically render select choices Django
I posted a screenshot below to hopefully make this easier to understand so I will reference it in my question. I am trying to create a recipe cost calculator app. I have 3 model namely Recipe, RecipeIngredient and Ingredient The user will add ingredients to the database and then create recipes using those ingredients throught the RecipeIngredient model. When creating an Ingredient the user selects a unit eg. (grams). Now when the user goes to create a Recipe (see screenshot below) I want to only display the units that are relevant to that ingredient and not all of them for eg. A user added Beef and the unit was grams now when the user is adding a RecipeIngredient to the Recipe I want them to only be able to select from the "Weight" category in the example (see screenshot below). The reason for this is because grams can't be converted to milliliters and so it shouldn't even be a choice. If anything is unclear or you need more information just let me know. Models Recipe Models from django.db import models from django.urls import reverse from django.contrib.auth import get_user_model from ingredients.models import Ingredient class Recipe(models.Model): """Store recipe information and costs""" class … -

For loop indentation is not taking place in jinja2 templating in vscode
I am writing a for loop or if else using jinja2 templating but it is not giving me indentation in vscode. Fore example, I wrote this: {% extends 'base.html' %} {% block content %} <h2>This is Item List</h2> {% for item in items %} <p>{{items}}</p> {% endfor %} {% endblock content %} But when I press Ctrl s or save it manually, it loses the indentation. The code becomes like this: {% extends 'base.html' %} {% block content %} <h2>This is Item List</h2> {% for item in items %} <p>{{items}}</p> {% endfor %} {% endblock content %} This is happening for for loops, if else and everything inside jinja2 templating. Not happening in normal python codes. This is not giving any error, but I feel distressed. How to solve it. -

Django migration gives psycopg2.errors.DuplicateTable: relation error
I have previously restored the database for the system, and while i tried to migrate through the django applicaion, the following error is thrown.

whats the right way for read MySQL database with django
I'm new to django I have a local application I wrote in python that writes scientific data to a MySQL database hosted on a digital ocean droplet that also runs django. I'm experiencing an intermittent problem where occasionally (maybe 1 in 3 tries) a page request produces a 'bad gateway' error message. Refreshing the page will normally produces the correct page. A page example is http://104.131.165.99/garage/ The problem is annoying and I'm not sure what the cause is but I never understood models in django and I'm not sure how to even clearly ask my question. My local application uses pymysql to connect to the MySQL database thats part of the server where django is hosted, in otherwords a mysql database thats NOT(?) really associated with the instance of django running on the server. The code in my django app (see below) that runs when a page is requested uses pymysql with a host address of 127.0.0.1 to read and manipulate the MwSQL data. Whether or not this is the cause of my problem, I always wondered if this was the proper way to read mysql data in django considering the app writing to that database is on a different … -
