Get list from two models (With addtional fields). Make Subquery
I have models Reserved and Room (default status is Free). And i want get list of all Rooms. Their statuses is Reserved (I have such table) Free (not price, state) Busy So in short i need to get all Rooms with their status. I don't need status fields and will not add it. No status field in my models. How can i get certain statuses? Shortly model class Room(models.Model): # Default all rooms are Free (Rooms state) number = models.ForeignKey(RoomNumber) expiry_date = models.DateTimeField() class Reserved(models.Model): visitor = models.ForeignKey(Visitor, on_delete=models.PROTECT) room = models.OneToOneField(Room) reserved_date = models.DateTimeField() begin_date = models.DateTimeField() I tried to do Subquery but no result :( reserved = Reserved.objects\ .filter(room=OuterRef('pk'))\ .filter(begin_date=timezone.now())\ .values(count=Count('pk')) Room.objects.annotate(reserved=Subquery(reserved[:1])) If 1 room is Reserved if 0 empty -
Learn about user status with token_for_business on Facebook
I want to delete the random facebook business id that was entered into the database years ago. An idea for that came to mind. Putting business id in the database on the facebook verification test. I entered the Facebook development environment. Here I wanted to test several business_ids in db. But I did not get the result I wanted. In the end, can I check with the token_for_business id to see if the user actually exists? -
Docker container does not recognize DJango Formtools
I have some code that uses DJango Form Tools (in particular, the SessionWizardView) . From what I can see, the Formtools appears to work outside a Docker Container but fails when it is used within one. The environment where it is working is development. The Docker container where it is not wokring is Production. The error message one gets is (in the log of the running contaner): from formtools.wizard.views import SessionWizardView ModuleNotFoundError: No module named 'formtools' **I have installed formtools on the C:\Users\dgmufasa>pip install django-formtools Requirement already satisfied: django-formtools in c:\work\software\python64bitv3.6\lib\site-packages Requirement already satisfied: Django>=1.8 in c:\work\software\python64bitv3.6\lib\site-packages\django-1.11.7-py3.6.egg (from django-formtools) Requirement already satisfied: pytz in c:\work\software\python64bitv3.6\lib\site-packages\pytz-2017.3-py3.6.egg (from Django>=1.8->django-formtools) I have added it to INSTALLED_APPS in the settings.py file INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', [..snip ..] 'formtools', ] I have used it as part of a program: from django.shortcuts import render, render_to_response from formtools.wizard.views import SessionWizardView #from django.contrib.formtools.wizard.views import SessionWizardView from django.contrib.auth.decorators import login_required [... snip ...] In this area (development) it all works - but - when taking the EXACT same code, creating a Docker file and putting it into production, I get errors. **requirements.txt for Docker build** file Django==1.11.7 psycopg2 Pillow==4.3.0 bcrypt==3.1.4 cffi==1.11.2 django-formtools django-phonenumber-field==1.3.0 googlemaps==2.5.1 geocoder==1.33.0 geopy==1.11.0 … -
Dynamic read-only field in Django Admin
In Django Admin I want all fields to be: 1) editable on creation 2) some of them on updating ( based on the instance fields values on creation). For example: 2-1.

Understanding a hairy SQL situation
I have a Django app with pymysql to connect to my MySQL instance. Following is my python code for a post request: if request.method == 'POST': body = json.loads(request.body.decode('utf-8')) db = connect_to('table_name', 'key') for json_variable in body['json_key']: record = db.findFirst({'user_id': user_id, 'date': body['date']}) if not record: db.create({'column_name':value}) else: db.update({'column_name':value}, {'user_id': user_id}) In this connect_to, findFirst, create and update are helper methods to connect to the database, find first record with parameters, create a new record and update a table with parameter 1 where parameter 2 is true. The issue is that in many situations, despite a record being present a new one is created and not updated as it should be. The django app itself is on heroku and the mysql instance is on AWS. -
celery task not processed by celery
total celery and django noob here, so sorry if the problem is trivial. Basically the problem is that any function defined by @app.task is not being processed by celery, it just runs normally as if celery isn't there. My celery_app.py file is - from __future__ import absolute_import import os from celery import Celery from django.conf import settings # set the default Django settings module for the 'celery' program. os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'project.settings') app = Celery(broker=settings.CELERY_BROKER_URL) app.config_from_object('django.conf:settings') app.autodiscover_tasks() if __name__ == '__main__': app.start() While my tasks.py file is - from project.celery_app import app @app.task def mytask(): ...

Django ORM Count by Related Field
I have the following models: class Profile(models.Model): pass class Team(models.Model): ... members = models.ManyToManyField("main.Profile", through='main.TeamMember') class TeamMember(models.Model): profile = models.ForeignKey('Profile') team = models.ForeignKey('Team') role = models.CharField(max_length=255) So, I try to order teams by count of profiles with a certain role, and I had a query, which doesn't work: Team.objects.filter(members__role='ExampleRole').annotate(example_role_count=Count('members')).order_by('example_role_count') It raises the following Exception: django.core.exceptions.FieldError: Related Field got invalid lookup: role because role is a TeamMember field, not Profile. So, how can I achieve ordering by count of members with a specified role? -

How to create equivalent LEFT JOIN query in Django's ORM (1.11)
With the following model setup (simplified for brevity): class Claim(models.Model): permalink = models.SlugField(max_length=255, blank=True, unique=True) author = models.ForeignKey(get_user_model(), db_index=True, on_delete=models.SET_NULL, null=True, blank=True) collaborators = models.ManyToManyField(get_user_model(), through='ClaimCollaborator', related_name='claims') # ...other fields class ClaimCollaborator(models.Model): claim = models.ForeignKey(Claim, db_index=True, on_delete=models.CASCADE) user = models.ForeignKey(get_user_model(), db_index=True, on_delete=models.CASCADE) # ...other fields I am trying to replicate the following SQL query in Django's ORM. SELECT * FROM claim c LEFT JOIN claim_collaborator cc ON cc.claim_id = c.id WHERE c.permalink = 'foo-bar' AND (c.author_id = 2 OR cc.user_id = 2) The logic I believe should be straightforward with usage of django.db.models.Q, but the bit I'm struggling on is the LEFT JOIN. Bit of a Django ORM noob, and I have attempted various usage of select_related() with the ClaimCollaborators model to no avail. Any ideas? -

max_length does not work
I have such field in my model: name = models.CharField(max_length=20, default='Anonymous') But when I enter more characters in that field, there is no errors, I can enter any amount of characters. And I can do it in my view, do it in admin/, there is no errors anyway. Somebody adviced me to make .full_clean() before saving entries, but it does not affect, this field still allows to enter more than 20 characters. Same with other fields. And I very, very, very sorry for my bad english. -

Trying to understand Django's communication between view and template
I come from a web2py background and find Django a much more complicated framework to learn and use than web2py. In my view I have: hr = dict(name="Some Name",photo="/static/images/HR.jpg",url="http://some.website.com/?page_id=3602"), js = dict(name="Some Name2",photo="/static/images/JS.jpg",url = "http://some.website.com/?page_id=3608") return render(request, "wos_2017_2/team.html", {team:[hr,js]}) In the template I have tried several things. First I tried to do a for loop which ended in no output. I do not understand how the template language handles what is passed to it through render So I tried this manually to try and figure out how I can use what is passed from the view: <h3>The data-management team</h3> <ul> <li>{{ team.0.name }}</li> <li>{{ team.js.name }}</li> </ul> Which shows an with two empty items. My first preference would be to use a for loop but after many hours of reading and searching inter alia Stackoverflow I did not succeed. I then tried: team = dict(hr = ["Some Name","/static/images/HR.jpg","http://some.website/?page_id=3602"], js = ["Someone Name2","/static/images/JS.jpg","http://some.website/?page_id=3608"]) return render(request, "wos_2017_2/team.html", team) with the following in the template: <h3>The data-management team</h3> <ul> <li>{{ team.hr.0 }}</li> <li>{{ team.js.0 }}</li> </ul> with the same result (an empty list). How do I do it? -
How to make periodic function by using Celery with Django?

Here is my models.py: class Question(models.Model): question_text = models.CharField(max_length=200) pub_date = models.DateTimeField('date published') def __str__(self): return self.question_text def was_published_recently(self): now = timezone.now() return now - datetime.timedelta(days=1) <= self.pub_date <= now class Choice(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) choice_text = models.CharField(max_length=200) votes = models.PositiveIntegerField(validators=[MinValueValidator(0)], default=0) def __str__(self): return self.choice_text Here is the urls.py : app_name = 'polls' urlpatterns = [ url(r'^$', views.IndexView.as_view(), name='index'), url(r'^specifics/(?P<pk>[0-9]+)/$', views.DetailView.as_view(), name='detail'), url(r'^(?P<pk>[0-9]+)/results/$', views.ResultsView.as_view(), name='results'), url(r'^(?P<question_id>[0-9]+)/vote/$', views.vote, name='vote'), ] And finally we have the tests.py part: ### SELENIUM ### class VoteTest(StaticLiveServerTestCase): @classmethod def setUpClass(cls): super(VoteTest, cls).setUpClass() cls.selenium = webdriver.Firefox() cls.selenium.implicitly_wait(10) Question.objects.create(question_text="Sample_question", days=1) Choice.objects.create(choice_text="Sample_choice", question=q, votes=1) def test_vote(self): self.selenium.get('%s%s' % (self.live_server_url, '/polls/')) self.selenium.find_element_by_xpath('//a[@id="1"]').click() # Here I get the "URL not found error", the URL is '.../polls/specifics/1/ As I said the URL is reachable from the webserver.

reset_sequence in pytest-django
