adding to a query set from another queryset django
I have a query set that looks like this. <QuerySet [<Room: localhost>, <Room: chat>]> which is inside room <QuerySet [<RoomShare: Shared room u'208349023840928', for company 2>]> which is stored inside roomshare If I print the second query to get the name of the room i just use. for x in roomshare: print(x.room.room_name) which gives me `Room Fun` I would like to add this Room_Fun to the first query set. And it should look like this <QuerySet [<Room: localhost>, <Room: chat>, <Room: Room_Fun]> I tried different method's but couldn't achieve the result I want. Also the second query set can have more than 1 roomShare, so I might have to use a forloop to add multiple of times to the first query set. -
Django 1.11 PostgreSQL multiprocess fail to work
Here's a website I've beening working on. It scrapes data from certain urls. I use multiprocessing module to make it faster, but the data cannot be saved. I tried put this under the worker function, but it still can't work.connection.close() Seems like the database just gets stuck in: data = Data(url=url, title=tile) ps: I'm using PostgreSQL 10, and Django 1.11.5, Python 3.5. def getSoup(url): # get beautifulsoup object from the url def getData(soup, url): title = getTitle(soup) # read title from the soup data = Data(url=url, title=title) data.save() print(url, 'Data saved!') def task(url): # connection.close() # I tried put this here, but it's not working soup = getSoup(url) # try for the first time while soup == 1: try: soup = getSoup(url) # if it failed to get soup, it'll return 1 and try again except TimeoutError: pass getData(soup, url) def scrape(): pool = multiprocessing.Pool(processes=10) pool.map(task, get_urls()) # get_urls is a urls generator pool.close() scrape() -
Django: can database migrations be reverse engineered?
I've been trying to wrap my head around how to avoid creating a mess with Django migrations. I tried "don't delete migrations" and for the most part that worked, but when I wanted to delete an app off my codebase, I struggled and fell back into a mess. I was thinking, it would be far easier to untangle these issue if one could: 1- delete all current migrations 2- create a migration from an existing database schema (rather than from Django models) <- this is the missing step 3- run migrate --fake to synch DB with migrations 4- run makemigrations to add any non-applied changes to the migration chain (this time from Django models) 5- run migrate to synch the DB with the new changes The only step that I don't know how to do is step 2. Is this doable? I don't know of any built in module or tool that does this so I'm wondering why not. Some research showed python manage.py inspectDB gets me partially through step 2. -

Django use templatetag API Wrapper
I'm writing a custom API wrapper for automating stuff on multiple devices having a REST API. Authentication to these devices is via csrf token.

Django OneToOneField post_save cant call int object
I want to extend my 'User' model with the 'Profile' model. To facilitate this I've created the following model. I wanted to have the linked 'Profile' model be automatically created with each new 'User' model. Based on some comments on stackoverflow / research on the internet (simpleisbetterthancomplex) I came with the following solution: from django.db import models from django.contrib.auth.models import User from django.db.models.signals import post_save from django.dispatch import receiver # Create your models here. class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, related_name='profile') #Pushup related stats total_pushups = models.IntegerField(default=0) best_consecutive = models.IntegerField(default=0) week_streak = models.IntegerField(default=0) save = models.IntegerField(default=000) @receiver(post_save, sender=User) def create_user_profile(sender, instance, created, **kwargs): if created: Profile.objects.create(user=instance) @receiver(post_save, sender=User) def save_user_profile(sender, instance, **kwargs): instance.profile.save() However, every time I run this (whether through unit tests or 'create superuser' - I have no vies yet, I'm practicing TDD) I get the following error: TypeError: 'int' object is not callable Does anyone here know what I am doing wrong? -

How to include a calendar management module easily within a Django project
I am developing a Python Django platform, using Django, html, and a bit a javascript. This platform aims to manage bookings. I am stuck on a calendar module which I could insert within my html pages. The calendar module would read schedule availabilties and redirect to a booking page when clicked on it. Ideally, I would like something similar to this website : https://www.doctolib.fr/medecin-generaliste/paris (class 'dl-search-result-calendar'). I know it might be coded in AngularJS and Ajax, although my knowledge of this 2 technos is very limited. My question is, what would be the easiest solution to insert such a calendar module, with booking redirect module ? Any help is welcome Thank you -

Call django rest framework CRUD methods from single page angular application

How to create a system using Django so that a naive user can edit the content of the Django website without using HTML code?
I have created a personal website for someone using Django (however it wasn't required since website is very simple, but it was their demand!). Now they want that they can edit the content of pages without editing HTML. They now want me to use Django-CMS, I again disagree as I don't think it is required (?) . What should I do to create a system so they can edit the webpage without messing with templates and HTML? The webpages contains few listings, say of 'Books', 'Recent Visits'... etc. I was thinking to create a model for each of them, and let them edit the database using admin, which will then be used by Django to create a dynamic page for their site. Do you think CMS would be a better choice (but then they don't really need me to do anything, they can do it by themselves!) ? I perhaps didn't put my problem properly, but if anyone can understand it, then please give me your suggestions. I can provide more details if anyone wants. -
