task queue in celery
I have a service that processes data. It is written in Python (Django) and uses Celery for making it asynchronous. Processing our data uses credits. You can also buy credits and this is triggered by a Stripe-webhook. Each action that involves credit changes is listed as a "job". I have 2 Celery tasks all adding a job to a certain JobId database. I use the "job" concept to keep track of which data is processed at which job. models.py: class JobId(models.Model): user = models.ForeignKey(User, blank=True, null=True, default=None) job_time = models.DateTimeField(auto_now_add=True) # current credit level credits = models.IntegerField(default=0, null=True, blank=True) # credit impact / delta of this job credit_delta = models.IntegerField(default=0, null=True, blank=True) tasks.py: task_1_buy_credits(user): # credit level of user is searched in jobs_database (the users last job) # adds one line in the JobId database with the users new credit balance task_2_use_credits(user,data): # upfront unknown amount of data get processed # credit level of user is searched in jobs_database (the users last job) # decide to process job completely or stop if credit level is insufficient My current issue is that when people start multiple jobs at a time, the previous job is not finished yet.

How to prevent creation of a record based on a related django-guardian permissions?
How do you prevent a model from being created by a specific user in the django admin if the user does not have a specific permission of a related object. So the object has an object level permission with django-guardian: CHANGE_RATE_PERM = 'change_rates' class Project(models.Model): ... class Meta: permissions = ( (CHANGE_RATE_PERM, 'Change Rates'), ) Permissions are assigned with: assign_perm( CHANGE_RATE_PERM, instance.account_manager, instance ) Then I have a related model called Rate that is related to the project: class Rate(models.Model): project = models.ForeignKey( Project, on_delete=models.PROTECT ) rate = MoneyField( max_digits=10, decimal_places=2, default_currency='ZAR' ) So I want to ensure that when a rate is created on django admin a check is made to see whether the user requesting the rate checks for the CHANGE_RATE_PERM for the the project. If there is no permission, an error is given. -

Django 1.11 - child template not inheriting from parent
I've read through similar stackoverflow problems and checked that I wasn't making the same mistake. I don't think this is an issue with URLs or Views as the Django-debug-toolbar shows that it's picking up the parent template, but the child template isn't extending that.

Django with Postgres - ProgrammingError, migrations not updating the database
Recently, I changed a model called 'Objects' by adding a 'description' field (which has null set to True). Ever since I migrated to the Postgres database hooked up to the Django project, I have received the following error whilst trying to access the 'Objects' model. ProgrammingError at /objects/results/ column objects_objects.description does not exist LINE 1: ...1, "objects_objects"."mapped_product_id" AS Col2, "objects_o... Objects model... class Objects(models.Model): mapped_product = models.ForeignKey(Product,related_name='p_objects',verbose_name='Product',null=True,blank=True,on_delete=models.SET_NULL) description = models.CharField(max_length=1000,null=True,blank=True) slug_key=models.SlugField(unique=True) is_active=models.BooleanField(verbose_name='Active',default=False) In the console, Django says migrations are all successful, and when running the local server it does not show that there are unapplied migrations. Any ideas on how to sync the database up with the models from scratch? I do not mind clearing my development database for this, and have already tried removing all of the previous migrations. I understand that this is somewhat vague at this point since I'm unsure what code I should post here - let me know if there is some code I should post here. -

Python/Django how to set model datetime field with html date field value
I want to assign values form a simple html form(I dont want to use Django model forms or widgets in this case). All of the fields work fine except the datetime one. Lets say the html form is as simple as this: <form action="{% url 'main:create' %}" method="post" class="row form"> {% csrf_token %} <div class="expense-block" id="expense-block-0" data-block="0"> <div class="col-md-2"> <div class="form-group"> <label for="id_name">Name:</label> <input type="text" name="name" class="form-control" required id="id_name"> </div> </div> <div class="col-md-2"> <div class="form-group"> <label for="id_created_at">Date:</label> <input type="datetime-local" name="created_at" class="form-control" required id="id_created_at"> </div> </div> </div> <input type="submit"> </form> As you can see for the date input i am using type="datetime-local" because I want to select both date and time. The model is simple: class Expenses(models.Model): name = models.CharField(max_length=200) created_at = models.DateTimeField() However when i save model I get error: The Expenses could not be created because the data didn't validate. Now the reason I am getting this error is because the 'create_at' value that i get from the post looks like this: 2018-03-09T11:11 So the question is, is it possible with Python to format this date to a normal datetime object? If not, what else can I do in my case? -

Using the URLconf defined in WisdomPets.urls, Django tried these URL patterns, in this order: admin/ ^$ [name='home'] ^adoptions/(\d+)/ [name='pet_detail'] The empty path didn't match any of these.

Django: Minimum disqus comments integration example in development
I want to test disqus comments in development mode. I know that django-disqus is the package that helps integrate disqus comments but can't really figure out the way forward. I have a Post model in models.py as follows. class Post(models.Model): title = models.CharField(max_length=250) slug = models.SlugField(max_length=300, unique_for_date='publish') author = models.ForeignKey(settings.AUTH_USER_MODEL) body = models.TextField() publish = models.DateTimeField() In my templates I have, {% extends "blog/base.html" %} {% block title %} Blog | {{post.title}} {% endblock %} {% block content %} <p> <b>{{post.title}}</b> </p> <p> {{post.body}}</p> <p>Written by: {{ post.author }} on {{ post.publish }}</p> <hr> {% endblock %} {% block domready %} {% endblock %} So, my question is: Is it possible to integrate Disqus in development on my local machine? If yes, please provide reference/blog/hints so that I can integrate disqus comments in my blog.
