Celery beat serving old (removed) task
Under supervisor, celery beat serves periodic tasks to celery workers for a Django app of mine. I have 4 tasks, task1, task2, task3, and task4. Recently I made a 5th task: task5. My problem is that I commented out task5 from my workers, removed its mention from settings.py and restarted celerybeat and my celery workers. But I still see task5 periodically showing up (throwing an error in the workers' logs naturally). Why is this happening, and how can I update the periodic tasks? In settings.py, I have: CELERYBEAT_SCHEDULER = 'djcelery.schedulers.DatabaseScheduler' CELERYBEAT_SCHEDULE = { 'tasks.task1': { 'task': 'tasks.task1', 'schedule': timedelta(seconds=45), }, 'tasks.task2': { 'task': 'tasks.task2', 'schedule': timedelta(seconds=60), # execute every 60 seconds 'args': (), }, 'tasks.task3': { 'task': 'tasks.task3', 'schedule': timedelta(seconds=90), # execute every 90 seconds 'args': (), }, 'tasks.task4': { 'task': 'tasks.task4', 'schedule': timedelta(seconds=90), # execute every 90 seconds 'args': (), }, } /etc/supervisor/conf.d/celerybeat.conf contains the following: command=python manage.py celery beat -l info directory = /home/myuser/myproject/ environment=PATH="/home/myuser/envs/myenv/bin",VIRTUAL_ENV="/home/myuser/envs/myenv",PYTHONPATH="/home/myuser/envs/myenv/lib/python2.7:/home/myuser/envs/myenv/lib/python2.7/site-packages" user=mhb11 numprocs=1 stdout_logfile = /etc/supervisor/logs/celerybeat.log stderr_logfile = /etc/supervisor/logs/celerybeat.log autostart = true autorestart = true startsecs=10 stopwaitsecs = 600 killasgroup=true priority=999 Ask me for more info if you need it.

Using third party Email system for Django Password Reset
I have a Django App hosted on Google Compute Engine(which doesn't allow port 25/465/587 to send Emails).

But when I use Django Reset Password, that email is still getting sent over by the Django Default Email System. Can this Django Default Email system for password Reset be changed ? If yes, Can someone please explain how it can be changed ? Thanks, -

Django Admin add edit/create buttons to Parent

Django get_or_create on reverse relationship
I'd like to use get_or_create instead of doing this: cart = client.cart cartitems_cart = cart.__cartitem_set if not cartitems_cart.filter(item=stockitem).exists(): cartitem = CartItem.objects.create(item=stockitem) else: cartitem = cartitems_cart.objects.get(item=stockitem) is it possible somehow? The models look like this: class CartItem(models.Model): item = models.ForeignKey(StockItem, blank=True) quantity = models.IntegerField(default=1, null=True) class Cart(models.Model): items = models.ManyToManyField(CartItem, blank=True) So, I need to get or create a CartItem that is related with a Cart. I'm not sure how to write that query. -
To how list group by values and values in that category
I want my template to display my group by category as a header, and then all the values for that group by category under it. For example, my table looks like this: ['John','Physics'] ['Jim','Physics'] ['Sam','Biology'] ['Sarah','Biology'] And I want the template to output this: Physics John Jim Biology Sam Sarah I'm not sure what to put in my veiws.py as I would usually do this in SQL --> first group by category, then return all results in that category. How would my veiws.py and template looks like to accomplish this? Thanks. My current veiws.py: def department(request): students = Students.objects.all().order_by('department') return render(request, 'department.html', { 'students':students, }) -
no module named AppConfig
I'm trying to run a server on my computer in Python/Django. In my installed_apps, I had a program called csvimport. It didn't work, so I had to install django-csvimport and I had to change it to csvimport.app.AppConfig in my installed-apps. However, I still get an importerror message saying "no module named AppConfig". (my version of django is 1.8, and django-csvimport is 2.4, by the way) Is this not the correct way to have csvimport in my installed_apps and my program? Thanks! -

Django refuses to accept my one-off default value for FloatField
I have a class and I'm trying to add a new FloatField to it. Django wants a default value to populate existing rows (reasonable). However, it refuses to accept any value I give it. You are trying to add a non-nullable field 'FIELDNAME' to CLASS without a default; we can't do that (the database needs something to populate existing rows). Please select a fix: 1) Provide a one-off default now (will be set on all existing rows with a null value for this column) 2) Quit, and let me add a default in models.py Select an option: -1 Please select a valid option: -1 Please select a valid option: -1 Please select a valid option: float(-1) Please select a valid option: -1.0 Please select a valid option: float(-1.0) Please select a valid option: How do I get it to accept my value? -
Django 1.9 angularjs 1.5 template tags
I know there are quite a few solution out there it seems as I've already done some searching. However, it seems the vast majority of them are for older versions Django and AngularJS. That said, if I'm using Django 1.9 and AngularJS 1.5 - what would be the "best practice" way to implement Django and AngularJS with the well known issue of conflicting template tags. I'm using AngularJS to implement a site search feature and need a way to display the results. It seems that {% verbatim %} and {% endverbatim %} would be the simplest, cleanest way to achieve this? -

Making a Twitter clone in Django, having trouble with displaying the right user when displaying tweets
I have user registration. Whenever I log in as a certain user, all the tweets are said to be tweeted by that user, even if it wasn't. forms.py from django.contrib.auth.models import User from django import forms class UserForm(forms.ModelForm): password = forms.CharField(widget=forms.PasswordInput) class Meta: model = User fields = ['username', 'password', 'email'] models.py from django.db import models from django.core.urlresolvers import reverse from django.utils import timezone from django.contrib.auth.models import User class Howl(models.Model): author = models.ForeignKey('auth.user', null=True) content = models.CharField(max_length=150) published_date = models.DateTimeField(default=timezone.now) like_count = models.IntegerField(default=0) rehowl_count = models.IntegerField(default=0) def get_absolute_url(self): return reverse('howl:index') def __str__(self): return self.content index.html {% block content %} <h2>Index.html timeline!</h2> {% for howl in howls %} <div class="howl"> <h2><strong>{{user.username}}</strong></h2> <p class="lead">{{howl.content}} - {{howl.published_date}}</p> <span>Rehowls: {{howl.rehowl_count}}, Likes: {{howl.like_count}}</span> </div><!--howl--> {% endfor%} {% endblock %} I know that using user.username in index.html is the problem.

Transfering existing users to python-social-auth
I have running django app with custom user model, that has "facebook_uid" field, that has been used for previous hand-written facebook login. Now I would like to transfer those existing facebook asociations to python-django-auth. I can just create records for those users to table social_auth_usersocialauth with obvious user_id and, provider and uid, but I am not sure if I can leave column extra_data empty (or empty json object). Is this correct approach? Is there anything else I need to do? Thanks! -
how to let user select two items to compare in html/django
I'm trying to create a simple webpage that'll let people select two items from search results to compare stats of each item.

Django-tables2: ValueError at /interactive_table/ Expected table or queryset, not str
I was following along with the tutorial for Django-tables2 tutorial (which can be found here: https://django-tables2.readthedocs.io/en/latest/pages/tutorial.html). I've fixed all the errors up until now, but I've hit one that I cannot solve. It says that my code expected a table or queryset, not a string. I've looked around, and all the solutions to this problem all blame the version being out of date, but I have updated it and I still get this error. Does anybody know what I'm doing wrong? Here is my views.py: from django.shortcuts import render from interactive_table import models def people(request): return render(request, 'template.html', {'obj': models.people.objects.all()}) Here is my models.py: from django.db import models class people(models.Model): name = models.CharField(max_length = 40, verbose_name = 'Full Name') Here is my template.html: {# tutorial/templates/people.html #} {% load render_table from django_tables2 %} <!doctype html> <html> <head> <link rel="stylesheet" href="{{ STATIC_URL }}django_tables2/themes/paleblue/css/screen.css" /> </head> <body> {% render_table people %} </body> </html> -
decorate or wrap the return value of a model field attribute
Suppose I have a Person model: class Person(models.Model): first_name = models.TextField() last_name = models.TextField() I need a way to wrap first_name and last_name at a request-response layer (e.g through middleware). For example, I may want to slightly modify the first_name. One way is doing it in every single place that needs it. Another way is to add a get_first_name() function that would do that for me, but this would require me to change thousands of occurrences of code directly accessing first_name. Another theoretical way, is to somehow wrap around or decorate the attribute through a middleware so that I can make modifications on the fly. Perhaps something like this: class ModifyFieldMiddleware(object): def process_request(self, request): Person._first_name = Person.first_name Person.first_name = modify_value(foo) #somehow pass the actual first_name here Is there a way to do this in django without major hacking? -

Post to nested fields with Django Rest Framework serializers
I have setup my serializer to return nested content successfully. However, I have not been able to post data within the nested fields.

django: is there something like crispy form for displaying a model?
This sounds like a LMGTFY question but I actually tried to look around on google and doesn't seem to find any. I am wondering if there is a module or app for django that handles displaying fields of a model beautifully since I am pretty sure it would look terrible if I do the front end manually. -
