How to add a form in an html page in django
I want to add comments form a specific html which has it's own views and models and I do not want to create a new html file like comment.html which will only display the form and its views. I want users to be able to comment right underneath a post, so that users don't have to click a button such as "add comment" which will take them to a new page with the "comment.form" and then they can comment. Basically want a page with all transfer news and their respective comments as well as a comment-form under the old comment. But I'm stuck. I can add comments manually from the admin page and it's working fine, but it seems that I have to create another url and html file to display the comment form and for users to be able to add comments(btw I'm trying to build a sports related website). Thanks in advance!

Django FileResponse don't download HTML file
I'm trying to download an pre-generated HTML file, but all that i've tried doesn't work. Searching StackOverflow i found that return FileResponse(open(file_path, 'rb')) will download a file, but intead of download, the HTML just is rendered on the tab. I think the problem is the browser receive the HTML and instead of display the "Save as" dialog just render it to the current tab. In my main template i have a form with target="_blank" tag, and a submit button that open (without AJAX) a new tab who suposed to download automatically the file. What i want: After i submit the code a new tab appears, the view related to that URL do some code (not related to the download) and after that process (that is working fine) download an HTML file to the device. The HTML exists and don't have any problem, te only problem it's that i want to DOWNLOAD the file but the browser display it instead. Note 1: Yes, i know that with right clic -> download i can download the HTML that i see, but this system is for non IT people, i need to do it the easest way possible. Note 2: I put the … -
DRF identify user by Bearer Token

Strange behavior when sending file to django server in vuejs
When sending my audio files in vuejs I kept getting errors 'the submitted data was not a file, check the encoding type on the form.'

How to "skip" submodule declaration on import

How to retrieve a stripe subscription id after a checkout session in a django project?
Here is my problem. I made a stripe subscription for my django project, and I used the checkout session method. I would like to retrieve the stripe subscription id, after the payment, to put it on my customer model, so I can make a cancel subscription method for the customer, because the method given by stripe require to have this id : stripe.Subscription.modify( *sub_id*, cancel_at_period_end=True ) or stripe.Subscription.delete(*sub_id*) The problem is that I can't find the id anywhere else than in my stripe account, where I have every informations I can need, but I can't find how to retrieve it through code after the payment has been done. I need to fill the field 'stripe_sub_id' in my customer model so i can make the cancel method work. Here is the method that creates the checkout session @csrf_exempt def create_checkout_session(request): if request.method == 'GET': domain_url = 'http://127.0.0.1:8000/' stripe.api_key = settings.STRIPE_SECRET_KEY try: checkout_session = stripe.checkout.Session.create( success_url=domain_url + 'projets/success?session_id={CHECKOUT_SESSION_ID}', cancel_url=domain_url + 'projets/cancelled/', payment_method_types=['card'], mode='subscription', line_items=[ { 'price': sub_price_id, 'quantity': 1, } ] ) return JsonResponse({'sessionId': checkout_session['id']}) except Exception as e: return JsonResponse({'error': str(e)}) And here is my script to activate the session //Get stripe publishable key fetch("/projets/config/") .then((result) => { return result.json(); }) … -
How to populate dropdown menu from Django database
I would like to create two dropdown menus from the data out of a database. I have been struggling with this for the past few hours and have no idea how to fix it. I have imported my CSV file to my database using Jupyter with sqlite3: import pandas as pd import sqlite3 lol = pd.read_csv('LeagueofLegends.csv') del lol['Address'] path = '#path to directory' cxn = sqlite3.connect(path + 'db.sqlite3') cxn.cursor().executescript('drop table if exists lol;') lol.to_sql('lol', cxn, index = False) cxn.close() As far as I know, everything went well, but now I'm at the point where I want to make a few dropdown menus from the data from the database. Down below I have included a snippet of the data. The two dropdowns I want to create are a blueTeamTag and a redTeamTag dropdown. I have tried this for hours but have no clue how to do this. Also, both the blueTeamTag and the redTeamTag contain duplicated, that I have to get rid of before putting it in a dropdown. I also included my views.py, models.py, and the HTML script where the dropdown menus should go. views.py: from django.shortcuts import render from django.http import HttpResponse, HttpResponseRedirect from .models import Lol # Create … -

How to trace code in a Django production system
My code behaves different in the production code, than on my development machine. I would like to debug/trace it. Since it runs on Heroku. I use PyCharm. AFAIK I can't insert import pydevd_pycharm; pydevd_pycharm.settrace(... into the code. I don't need a fancy GUI a command-line tool would be fine, too. I would be happy if I could see all lines which get executed during a particular http request. How to solve this for production systems? -
Converting .csv string data into DateField type in Django models.py
I am using Python 3.7 on Debian 10 I have a number of pre-existing .csv files with these columns: first_name, last_name, birthdate, phone, email I am importing them into a postgres database with Django as the framework. My Django model: from django.db import models class User(models.Model): first_name = models.TextField(blank=False, null=False) last_name = models.TextField(blank=False, null=False) birthdate = models.TextField(blank=True, null=True) phone = models.TextField(blank=False, null=False) email = models.TextField(blank=False, null=False) Custom Django Management Command to import file import_users.py: class Command(BaseCommand): def handle(self, *args, **options): users_file = open(f'{settings.DATA_IMPORT_LOCATION}/users.csv', 'r') for counter, line in enumerate(users_file): line_fields = line.split(',') first_name = line_fields[0] last_name = line_fields[1] birthdate = line_fields[2] phone = line_fields[3] email = line_fields[4] u = User() u.first_name = first_name u.last_name = last_name u.birthdate = birthdate u.phone = phone u.email = email u.save() Output sample when running the following Django ORM query : > for u in User.objects.all(): print(u.birthdate) Output: birthdate 2015-05-28 2009-06-14 2007-01-01 2007-02-17 2008-05-16 2013-01-19 2008-07-24 2015-05-01 2007-06-03 2007-01-17 When birthdate = models.TextField is set to TextField, I can import these .csv files into my Postgres database successfully with my management command. This makes sense because all the .csv data are strings. However, I want to correctly set the model to read as a date, … -
What shall I use for full text search and fuzzy search on a social network django site with a postgresql database?
So, I was looking for a search engine for my new django project with a postgresql database and I ended up with elasticsearch and sphinx. I've chosen the second one, because I thought that if you're searching in a lot of posts you need a fast search, which uses less memory, but after looking at realization of sphinx I went up like, "How do I do that on python and can I do fuzzy search with it?". I've found few django-sphinx libraries, but they seem to be abandoned (last update was 5 years ago), and in sphinx documentation I didn't find anything about django, just few mentions of python. So, is sphinx still alive and how can I use it with django, or should I choose another engine for my tasks? -
