What would I miss, if I don't use any authentication in django and login the user using django query filter with a manually hashed password
I have seen the default user authentication and custom user uathentication in django, I would like to know what would I be missing if I just login a user by using a normal query like, ____.objects.get(password = ______, email = ______) and just hash the password stored in the model column.And store the login details in session and clear them on logout. Would it ruin the security altogether or is it something else I wouldn't get which is found in the normal django authentication? -

Booking system for fitness / gym company - Where to store booking data, what django-models should I use?
I have to make (high school project) booking/reservation system for fitness / gymnastics service company. Users (clients) can have: tickets - for 1 hour (on 1 day) - "single ticket" subscription - 1 hour a day for one, two or three months. Overall, I have some idea how to make this application, but only need help with choosing best / optimal Django model for storing booking / reservation information. Assuming that there can be maximum N ( N ~ 15) persons in fitness club at the same time, I can sell limited number of tickets and subscriptions for particular day/hour. Where (what Django model suits best) should I store booking / reservation informations, For example: User No. 0001 is taking fitness at Monday, 25 January, 2021, 5 pm to 6 pm (single ticket) User No. 0002 is taking fitness at Friday, 30 January, 2021, 11 am to 12 am (single ticket) ..... User No. 0055 is taking fitness every weekday from 3 pm to 4 pm for whole January and February (subscription) ..... etc. What Django model do You recommend in my case? -
Django and Heroku - Migration is applied before its dependency
I'm having trouble getting my Django web app from a local server to Heroku. To try and troubleshoot I created a new app from scratch and managed to push that through to Heroku with no problems. The issue comes when I add class User(AbstractUser): pass to models.py, then run makemigrations and migrate. The error is: django.db.migrations.exceptions.InconsistentMigrationHistory: Migration admin.0001_initial is applied before its dependency mainapp.0001_initial on database 'default'. One thing that might be causing it is that I'm using sqlite3 on localhost then Postgres on the Heroku server (although I'm not advanced enough to know if that is actually the problem!) Also my gitignore file contains: /venv __pycache__ db.sqlite3 mainapp/static/ Should it also include the migrations folder? Any help or ideas would be appreciated!

Jinja .css template logic
I am wiring my framework to wagtail. It is a custom module css framework called reely.io that is made for Hubspot. It has jinja variables for breakpoints, colors, etc. one of the variables is a multiplier for padding and margin settings. I have the css file set up and coming through to the template. the issue is with any logic in the css file: {{ spacing_multiplier * 1 + 'px' }} {{ break_sm + 30 + 'px' }} Yes, this works in Hubspot's HubL, which I always considered a derivative of Jinja, but the syntax is a bit different. am I doing it wrong? views.py from django.views.generic import TemplateView class Themes(TemplateView): template_name = "css/reely.css" content_type = "text/css" def get(self, request, *args, **kwargs): context = self.get_context_data(**kwargs) ''' Responsive Breaks ''' context["break_xl"] = 1773 context["break_lg"] = 1292 context["break_md"] = 768 context["break_sm"] = 576 context["break_xs"] = 396 ''' Spacing Multiplier ''' context["spacing_multiplier"] = 10 ''' Font ''' context['google_font_link'] = "https://fonts.googleapis.com/css2?family=IBM+Plex+Sans:wght@300;400;600;700&display=swap" context['font_family_1'] = "'IBM Plex Sans', sans-serif;" ''' Color Set 1 ''' context["primary_color"] = '#333333' '''rgb(51,51,51)''' context["secondary_color"] = '#555555' '''rgb(85,85,85)''' context["tertiary_color"] = '#FFFFFF' '''rgb(255,255,255)''' ''' Color Set 2 ''' context["primary_font_color"] = '#333333' '''rgb(51,51,51)''' context["secondary_font_color"] = '#555555' '''rgb(85,85,85)''' context["tertiary_font_color"] = '#FFFFFF' '''rgb(255,255,255)''' ''' Color Set … -

For some requests, the django app will return a 200, with an x-accel-redirect header of the form: /document_store/<PROTOCOL>/<PRE-SIGNED S3 URL>. Expected behaviour: Nginx intercepts the response with the x-accel-redirect header, and instead serves the file from the pre-signed s3 url. Actual behaviour: Django successfully returns a 200, with the header set as expected. Nginx intercepts this request, and returns a 403. I have logged out the contents of the x-accel-redirect header, and passed <PROTOCOL>://<PRE-SIGNED S3 URL> to curl, which results in the file being downloaded successfully, so I am confident that: The header is being constructed properly The pre-signed header gives … -

Django Group By Permutations of ManyToManyField
I'd like to perform a group_by on a ManyToManyField habit_type = models.ManyToManyField(HabitType, blank=True), but not on every single existing element but on the existing permutations. E.g. currently there are 7 existing elements which are referenced to and with the query below it is grouped by each element. I'd like to group by the existing permutations like (1,2), (1,3,5), (1,4,6,7) But I do not want all possible combinations which would be a little bit too much... result = obj.registration_set.values(habit_type=F('participantpersonal__habit_type'))\ .annotate(number_personal=Coalesce(Count('participantpersonal__habit_type'), 0)) return result As example I have 6 entries with the habit (1,2) the current output is: { "habitTypeGroup": 1, "numberGroup": 6 }, { "habitTypeGroup": 2, "numberGroup": 6 } And my wished output is: { "habitTypeGroup": [1,2], "numberGroup": 6 }, Thanks for your help in advance -
Receiving a hidden input trough a submit button that has also other functionalities
I am building a django app in which the user has to write a sentence in a text box. After that the user has to click on continue and the sentence gets sent to the server and received by it. then it returns the next html page and with the sentence as context data for the render function. Now on this second html page the user has to record an audio of a word he sais. The word is then turned into a string and after that sent to the server trough a submit button. Since I passed the sentence to the second html page I can put a hidden input that has the sentence as value on the second html page. But now I would like that this sentence(the hidden input value) gets sent to the server with the word as a string. And this is what I tried but it does not work and I do not understand why. This is the impotant part of the second html page: <div id='result' class='voc'> Your text will appear here </div> <br> <div id= 'record'> <button onclick="startConverting()" class='btn btn-info btn-sm' id="re">record</button> <form action="/audio_data" method="POST"> <button class='btn btn-info btn-sm ml-3' value="Send" id="send" … -

Filter Djangos Admin list_display and inline
I have a table with films which is connected through intermediate table to to the table Person, which has name and role (writer, actor, director) a person. I am now searching a way to display writers, actors and director separately in list_display.
