How can I use exclude or filter with CharField?
I have a Good model with this Field: Size = models.ManyToManyField('Size') And Size model: class Size(models.Model): size = models.CharField(max_length = 15) def __str__(self): return self.size In views.py I need to exclude 1 size, so I try: good1 = Good.objects.get(id = good_id) good1.Size.exclude(size = 'XS') But exclude doesn't work... I think it's because of impossibility to compare size field with string 'XS' How can I fix it? -
How to set correct path in anchor tag
I'm working on a simple Django app. Right now I can link different pages via anchor tags using href="{ url 'name'} which I believe is the "Django way to do things". The problem is that as soon as I try to link a file that exists in a different location, I get an error. I've tried changing the name, function, and path, but I'm stuck. The errors vary, but it's usually related to trying to find pyoop.html in the wrong location. The only difference really is the pyoop.html is inside an "extra folder" which is not the case for the other files. # views.py def pyoop(request): return render(request, 'book/pages/pyoop.html') #urls.py urlpatterns = [ ... path('py-oop/', views.pyoop, name="book-pyoop") ] #index.html <a href="{ url 'book-python-oop'}">Link to Python-oop</a> pyoop.html is the only file inside the 'pages' folder, everything else is inside the 'book' folder. -

Django not uploading staticfiles to Amazon S3
I am trying to upload my static files onto Amazon S3 but it is still collecting the static files on a local folder. Any idea of how I can get my Django collectstatic to upload onto S3? Here are the relevant code bits: Using Boto and django-storages.

Optimizing Django REST Framework queries using prefetch_related
I'm not quite understanding the concept of prefetch_related for optimizing the related_name queries. However I seem to be in much need of it at this moment. I wish to optimize the following queryset as I have a bunch of similar looking queries: return Customer.objects.filter( Q(company__administrators__user=user) | Q(company__employees__employee_roles__user=user, company__employees__employee_roles__group__permissions=40) | Q(projects__project_roles__user=user, projects__project_roles__group__permissions=40, access='Restricted') | Q(projects__schedules__schedule_roles__user=user, projects__schedules__schedule_roles__group__permissions=40, projects__access='Restricted', access='Restricted') | Q(customer_roles__user=user, customer_roles__group__permissions=40) ).distinct() What would be the optimal way to do this using prefetching? Currently this query takes about 10 seconds on the development server, compared to < 1 second when returning Customer.objects.all(). Thus I have figured it boils down to the query and not serialization of the data. -
Creating input view for many to 1 relationship in Django
I'm attempting to create a page where users can input a recipe. Users would need to name the recipe, then input a list of ingredients and steps to follow during the recipe. I've set up 4 models Recipe - stores the name as well as the user inputing the recipe Ingredients - stores all ingredients possible (with potential to add new ingredients) Recipe_Ingredients - pairs unlimited number of ingredients to a recipe Step - allows user to enter an unlimited number of steps for a recipe I'm able to input recipes through the admin page, however this is: A. clunky B. doesn't allow non-admins to enter new recipes from django.db import models from django.contrib.auth.models import User # Create your models here. class Ingredient(models.Model): name = models.CharField(max_length=500, blank=False, null=False) link = models.CharField(max_length=500, blank=True, null=True) def __str__(self): return self.name class Recipe(models.Model): title = models.CharField(max_length=250, blank=False, null=False) notes = models.TextField(blank=True, null=True) author = models.ForeignKey(User, on_delete=models.CASCADE) def __str__(self): return self.title class Recipe_Ingredient(models.Model): recipe = models.ForeignKey(Recipe, on_delete=models.CASCADE) ingredient = models.ForeignKey(Ingredient, on_delete=models.CASCADE) unit = models.ForeignKey(Unit, on_delete=models.CASCADE, blank=True, null=True) amount = models.DecimalField(decimal_places=3, max_digits=10000) class Step(models.Model): recipe = models.ForeignKey(Recipe, on_delete=models.CASCADE) step_number = models.IntegerField(default=1) step = models.TextField(blank=True, null=True) def __str__(self): return self.step I'm hoping to create a page where … -

Getting same thread id inside celery workers
I tried getting the current thread id and process id while running a task inside a celery worker process. I have set prefetch multiplier to 1 and I have 4 cpu core machine, so there will be 4 worker processes running for each workers. I have only 1 worker running ( 4 worker processes). As per my understanding each of the worker processes actually handles the execution of task. When I run 4 tasks simultaneously I tried getting the process id and thread id inside the task using os.getpid() and threading.get_ident() respectively. To no surprise, for every task running I got the same set of 4 process_id (as there are 4 worker processes running), but the thread id for each of the process are same. I am not able to understand how is this possible. Following is my observations when running tasks: > log: pid id: 513, t_id 140373758563328 > log: pid id: 514, t_id 140373758563328 > log: pid id: 513, t_id 140373758563328 > log: pid id: 513, t_id 140373758563328 > log: pid id: 513, t_id 140373758563328 > log: pid id: 513, t_id 140373758563328 > log: pid id: 578, t_id 140280371217408 > log: pid id: 579, t_id 140280371217408 -

Django on Nginx subdirectory redirects to root
I have Django 2.2 and am trying to serve it to http://myserver.com/application using Nginx proxy pass. If I try and go to myserver.com/application/admin I get redirect to myserver.com/admin immediately. Is this a setting I should be specifying in Nginx or in Django to avoid this? Django is running in gunicorn, see Nginx.conf: location /static { alias /home/simernes/workspace/django_server/env/static; } location /application { proxy_pass http://localhost:8000/; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto http; proxy_buffer_size 128k; proxy_buffers 8 128k; proxy_busy_buffers_size 256k; } Finally, this is what my urls.py looks like in a project folder "backend": from django.contrib import admin from django.urls import path from django.conf.urls import url, include FORCE_SCRIPT_NAME="/application" STATIC_ROOT="/home/simernes/workspace/django_server/env/static/" app_name='backend' urlpatterns = [ path('admin/', admin.site.urls), url(r'^', include('api.urls', namespace='api')), ] Furthermore, when I go to the root of myserver.com/application I get an error of 404 not found and: Using the URLconf defined in backend.urls, Django tried these URL patterns, in this order: admin/ ^ auth$ [name='auth'] The current path, /, didn't match any of these.

How to pass contenteditable text to value attribute in django html file

How to structure a daily habit tracking app
Background I'm a personal trainer and trying to build an app that tracks whether or not my clients are working on their daily habits (and bugs them about it at a chosen time every day). I'd love to hear if any of you all have ideas on how to structure this as I'm new to both Django and coding in general. Models I currently have two models: Habits and Checks. Habits represent "What are you working on improving?" and have a ForeignKey to a user. Checks represent "Did you complete your habit today?" and have a ForeignKey to a habit. Current status There is a nice solution where you create all the Checks for a Habit based on it's end date, but I'm trying to structure this with an indefinite end date because, as a coach, then I can show hard data when someone isn't making progress. Though I am still willing to accept that maybe this app would work better if habits had deadlines. I wrote a custom manage.py script that Heroku runs automatically at the same time every day, but that doesn't scale with users' individual time zones. I run it manually on my local computer. I originally … -
how to compare time spans in python?
Say I have 2 sets of time spans. So one is from 10:00 am to 12:00 pm, the other from 11:00 am to 13:00 pm, both on the same day. How can I easily calculate to find out if they overlap? My code is irrelevant, but just for understanding the use case - I'm developing a Django app where I want to allow building some sort of schedule, something like this: class TimeSpan(models.Model): start = models.DateTimeField() end = models.DateTimeField() class Worker(models.Model): name = models.CharField(max_length=100) limitations = models.ManyToManyField(TimeSpan) Class Shift(models.Model): workers = models.ManyToManyField(Workers) timespan = models.ForeignKey(TimeSpan) I need to be able to compare a TimeSpan object of shifts, with the limitations of each worker. What would be a good way to do that? -

Automatically adding a slash at the end of a url
I've got all urls configured correctly, with a trailing slash. Now, whenever I visit a correct url that has no trailing slash, I get the "homepage" (since this is the page to show when a url is wrong). This is a pain in the ass since the url is 'somewhat' correct. I've tried to explicitly enable this with APPEND_SLASH = True in the settings.py but without any success. I'm still in the development phase so no weird rewrite rules from a server. What could be the cause of this? Thanks in advance! -

She can also view her previous notifications (basically like facebook notification). This is not email notification or a success/warning type one time notification. I want to know the right track to follow. Do I use django-notifications or django-messages-framework? Where is the use of channels and web sockets in all of these? My steps: 1) create a notification app 2) create a notification model (what fields do I put here if since django-notification already has actor, verb, action object and target fields?) 3) Do i have to create forms.py? How is the notification message getting passed? 4) What view do I put in views.py? (please give an example code) If there is any example project that implemented the notification system please provide a link.
