Mezzanine Fabric deployment, PSQL issue - "Error: role "project" already exists"
Having huge troubles deploying Mezzanine on digitalocean, and I'm taking it step by step to figure out all the small issues individually. Running "fab create" results in successfully (I guess?) setting up the virtualenv, but when it comes to setting up the PSQL database, it errors with the following (full output): [1xx.xx.xxx.xxx] Executing task 'create' ←[1;32m------ create ------←[0m ←[1;34m$ ←[0m←[1;33mlocale -a←[0m←[1;31m ->←[0m [1xx.xx.xxx.xxx] Login password for 'adm': ←[1;34m$ ←[0m←[1;33mmkdir -p /home/adm/mezzanine/project←[0m←[1;31m ->←[0m ←[1;34m$ ←[0m←[1;33mmkdir -p /home/adm/.virtualenvs←[0m←[1;31m ->←[0m Virtualenv already exists in host server: project Would you like to replace it?

Set up django-celery-email for local dev
It seems the best way to send emails from the django-allauth app asynchronously is to simply install django-celery-email. But the packages warns that This version requires the following versions:Python 2.7 and Python3.5, Django 1.11, 2.1, and 2.2 Celery 4.0 I've only been using python for several months and never encountered a situation where two python version are needed on a project. And I'm using the official recommendation of pipenv for local development. A quick google shows that it isn't possible to have two python interpreters installed in the virtual environment. Since the plugin seems so popular I wondered how others were setting it up? Apologies if I've missed something major that explains this. A bonus answer would also take into account that I am using docker and the docker image will install the python packages like this. RUN pipenv install --system --deploy --ignore-pipfile Many thanks in advance. -

as for the title I have this problem with validation in Django.

How to implement User system for job board (I need employers to be able to register and create posts)?
I am creating a job board where users can search a zip code and see jobs in their area. I have the following models.py: class Business(models.Model): name = models.CharField(max_length = 150) address = models.CharField(max_length = 150) city = models.CharField(max_length = 150) zip_code = models.CharField(max_length = 10) state = models.CharField(max_length = 30) phone_number = models.CharField(max_length = 10) class Job(models.Model): business = models.ForeignKey(Business, on_delete = "models.CASCADE") #when the referenced object is deleted, also delete the objects that have references to it. title = models.CharField(max_length = 100) description = models.CharField(max_length = 500) zip_code = models.CharField(max_length = 10) def save(self, *args, **kwargs): zip_code = self.business.zip_code super(Job, self).save(*args, **kwargs) To use the website to look for jobs, you do not have to sign in. However, I obviously need employer's to be able to create an account so that they can register a business and post jobs for said business.

DRF - How do I link back from model class with PrimaryKey to model class with ForeignKey
I have two models Job and JobDescription. I have a ForeignKey jobid defined in JobDescription. The django-rest-framework does its magic and finds the automatically created PK id in Job to link to. In serializers.py JobDescriptionSerializer jobid will give me a hyperlink to the Job id. So far so good. At this moment however, this is a one way street (JobDescription -> Job). I would like to add a field to Job model/serializer that will allow hyperlinking the other way around as well (Job -> JobDescription). I went through the Django models documentation around ForeignKey and there are some references to forward/backward relationships, but how do I implement this in the rest-framework models/serializers? Thanks for your help in advance! models.py: class Job(models.Model): title = models.CharField(max_length=100, default='') type = models.CharField(max_length=20, default='') location = models.CharField(max_length=100, default='') created_date = models.DateTimeField(auto_now_add=True) class Meta: ordering = ['id'] def __str__(self): return self.title class JobDescription(models.Model): jobid = models.ForeignKey(Job, related_name='desc2job', on_delete=models.CASCADE) description = models.TextField(blank=False) created_date = models.DateTimeField(default=timezone.now) class Meta: ordering = ['id'] def __str__(self): return str(self.jobid) serializers.py: class JobSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Job fields = ( 'url', 'id', 'title', 'type', 'location', 'created_date') class JobDescriptionSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = JobDescription fields = ('url', 'id', 'jobid', 'description', 'created_date') -
Django Testing - authenticate() returns None
Working on making some unittests with Django, and trying to make some testing with the login process with the login form. I am using modified User model just to make the email field unique; otherwise nothing drastically different. account/views.py def post(self, request): # Retrieve the username and password username = request.POST['username'] password = request.POST['password'] # Create a user object from authentication, or return None user = authenticate(username=username, password=password) # Check if user was created if user is not None: # Rest of the code, irrelevant... account/test_views.py def test_account_login_POST_successful_login(self): # Create a user to test login CustomUser.objects.create_user( username='test_user', email='test_user@intranet.com', password='flibble' ) response = self.client.post(self.login_url, { 'username': 'test_user', 'password': 'flibble' }) self.assertEqual(response.status_code, 301) account/models.py class User(AbstractUser): # Make the email field unique email = models.EmailField(unique=True) project/settings.py # Authentication AUTH_USER_MODEL = 'account.User' Funny thing is that login works normally on the web app, but when testing it always returns None. I've tried to check_password() with the created user, and it returns true in both the test method and the view method. I've also tried putting in AUTHENTICATION_BACKEND = ['django.contrib.auth.backends.ModelBackend'], but no go. -
Celery: different settings for task_acks_late per worker / add custom option to celery
This question is a follow up of Is there any way to find out the hash value of two files? I had a problem with celery (see the question that I follow up) and in order to resolve it I'd like to have two celery workers with -concurrence 1 each but with two different settings of task_acks_late. My current approach is not very beautiful. I am doing the following: in settings.py of my django project: CELERY_TASK_ACKS_LATE = os.environ.get("LACK", "False") == "True" This allows me to start the celery workers with following commands: LACK=True celery -A miniclry worker --concurrency=1 -n w2 -Q=fast,slow --prefetch-multiplier 1 celery -A miniclry worker --concurrency=1 -n w1 -Q=fast What would be more intuitive would be if I could do something like: celery -A miniclry worker --concurrency=1 -n w2 -Q=fast,slow --prefetch-multiplier 1 --late-ack=True celery -A miniclry worker --concurrency=1 -n w1 -Q=fast --late-ack=False I found Initializing Different Celery Workers with Different Values but don't understand how to embed this in my django / celery context. In which files would I have to add the code that's adding an argument to the parser and how could I use the custom param to modify task_acks_late of the celery settings. -

gunicorn vs celery for concurrency in django
In Django webapp that's deployed, I get a POST request from external source in views.py As soon as post request is received, I modified post function to do certain action and deliver results(1.1.1.1 is endpoint) in views.py def post(self, request, *args, **kwargs): #do some action #deliver results to 1.1.1.1 In this case, I'm currently running task as the request comes. For instance, if 5 requests come in at once, it's currently processing one by one. But, I'd like to process all requests at once(assuming there are enough server load) and deliver results back. Would increasing workers in gunicorn solve the issue of concurrency or would it be better to utilize job queue like celery? I need something lightweight. If gunicorn is enough, how many workers would need to be set? And what is best practice method? -
Assign value to one-to-many field through django code
I am trying to assign value to a database entry that is defined using the models.ForeignKey. How should I refer to the variables in the referred model?

What are the directives available in django similar to angular directives?
Do we have any directives in django similar to Angular directives like ng-show, ng-if, ng-for etc? When I worked on Angular, those directives are very helpful to me to finish my work faster. For example: how will you use a for loop in templates of django? -
Quiero que todos los navegadores acepten la coma para decimales
Tengo un formulario que en Firefox me acepta la coma para separar los decimales pero con Chrome me acepta el punto. Quisiera que los dos navegadores me acepten siempre coma; quiero que sólo se pueda ingresar números como 560,25 o 1250,75, por ejemplo. Estamos usando HTML5, en un proyecto con Python/Django. -
How to filter models efficiently in Django?
I have a website which will have many companies (model instances) and each company will have many users (model instances). What is the best way to separate the users by company so that the users of each company are all segregated from each other? All the ways I am currently thinking about doing this seems to use some sort of filtering in every section of the site which seems very inefficient. I already used Django's Groups for different employee types. Should groups be applied at the top of the chain (i.e. companies)? Even if I applied companies to groups I would probably be filtering at the template level quite often which seems inefficient and "un-pythonic". What are the best practices here?
