Postgre: 2 different query but same result
I have problem with my queries in postgre sql. First Query: SELECT first_name, last_name, service_name, max(usluga) FROM ( SELECT first_name, last_name, service_name, count(scheduler_scheduleevents.id) as usluga FROM workers_workers LEFT JOIN scheduler_scheduleevents ON scheduler_scheduleevents.worker_id = workers_workers.id AND is_start_time = True AND is_active = False AND ( scheduler_scheduleevents.date < %s or ( scheduler_scheduleevents.date = %s and time < %s ) ) LEFT JOIN user_settings_userservices ON user_settings_userservices.id =scheduler_scheduleevents.service_type_id WHERE workers_workers.salonid_id= %s AND scheduler_scheduleevents.worker_id = %s GROUP BY workers_workers.id, service_name) as x GROUP BY x.first_name, x.last_name, x.service_name And Second: SELECT first_name, last_name, service_name, min(usluga) FROM ( SELECT first_name, last_name, service_name, count(scheduler_scheduleevents.id) as usluga FROM workers_workers LEFT JOIN scheduler_scheduleevents ON scheduler_scheduleevents.worker_id = workers_workers.id AND is_start_time = True AND is_active = False AND ( scheduler_scheduleevents.date < %s or ( scheduler_scheduleevents.date = %s and time < %s ) ) LEFT JOIN user_settings_userservices ON user_settings_userservices.id =scheduler_scheduleevents.service_type_id WHERE workers_workers.salonid_id= %s and scheduler_scheduleevents.worker_id = %s GROUP BY workers_workers.id, service_name) as x GROUP BY first_name, last_name, service_name First query should give me only 1 service which was made most time and second query should give me too only 1 service which was made least times.

Django on Elastic Beanstalk "requirements.txt" is invalid
I'm trying to deploy a django project with Elastic Beanstalk cli. I followed the Official Amazon Tutorial as well as this Tutorial on realpython.com. The Deploymentprocess works fine as long as I stick to a newly created Django Project with just a view dependencies for pip.

Django With MSSQL using Pyodbc: Model Forms not being saved

Testing performance of container to ensure SLA
There are three responsibilities: Container provider: Provide a computing container with enough performance. In this case virtual machine with full linux root access. Application provider. That's us. We provide a Django app QA: They are testing that the service of our application has enough performance. If QA thinks the performance is not good enough, they blame us, the application provider. How can we ensure that the container is fast enough? Is there a common way to test the performance of a provided container? Background: I don't know (and I don't want to know) if the hypervisor is running VMWare, kvm or different. I would like to have a simple way to test the performance of the container every 15 minutes. The testing should not slow down the service, since it is running in production. -
add_periodic_task doesn't schedule the task with Celery 4.0.1
I'm using Celery 4.0.1 with Django 1.10 and I have troubles scheduling tasks (running a task works fine). Here is the celery configuration: os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'myapp.settings') app = Celery('myapp') app.autodiscover_tasks(lambda: settings.INSTALLED_APPS) app.conf.BROKER_URL = 'amqp://{}:{}@{}'.format(settings.AMQP_USER, settings.AMQP_PASSWORD, settings.AMQP_HOST) app.conf.CELERY_DEFAULT_EXCHANGE = 'myapp.celery' app.conf.CELERY_DEFAULT_QUEUE = 'myapp.celery_default' app.conf.CELERY_TASK_SERIALIZER = 'json' app.conf.CELERY_ACCEPT_CONTENT = ['json'] app.conf.CELERY_IGNORE_RESULT = True app.conf.CELERY_DISABLE_RATE_LIMITS = True app.conf.BROKER_POOL_LIMIT = 2 app.conf.CELERY_QUEUES = ( Queue('myapp.celery_default'), Queue('myapp.queue1'), Queue('myapp.queue2'), Queue('myapp.queue3'), ) Then in tasks.py I have: @app.task(queue='myapp.queue1') def my_task(some_id): print("Doing something with", some_id) In views.py I want to schedule this task: def my_view(request, id): app.add_periodic_task(10, my_task.s(id)) Then I execute the commands: sudo systemctl start rabbitmq.service celery -A myapp.celery_app beat -l debug celery worker -A myapp.celery_app But the task is never scheduled. I don't see anything in the logs. The task is working because if in my view I do: def my_view(request, id): my_task.delay(id) The task is executed. If in my configuration file if I schedule the task manually, like this it works: app.conf.CELERYBEAT_SCHEDULE = { 'add-every-30-seconds': { 'task': 'tasks.my_task', 'schedule': 10.0, 'args': (66,) }, } I just can't schedule the task dynamically. Any idea? -
Add field to AbstractUser admin page
I have an AbstractUser class in models.py file in order to extend the django user default class, class Profile(AbstractUser): address = models.CharField('Address', max_length=255, null=True) In my admin.py, class ProfileAdmin(UserAdmin): pass Everything works fine, but when I try to add my profile field, the address field does not appear in admin: class ProfileAdmin(UserAdmin): fieldsets = ( (None, {'fields': ('username', 'password')}), (_('Personal info'), {'fields': ('first_name', 'last_name', 'email','address')}), (_('Permissions'), {'fields': ('is_active', 'is_staff', 'is_superuser', 'groups', 'user_permissions')}), (_('Important dates'), {'fields': ('last_login', 'date_joined')}), I add 'address' field to fieldset variable but when I go to my Profile admin page 'address' field does not appear. Is there anyway to add fields from my Profile class to my Profile admin page? Thanks in advance, -

Sending data from view.py to a javascript in django
I know similar questions have been asked before but I am very new to django and js. I have tried many solutions but I am not able to make sense of many and able to run them. So I am writing my code and the solution that I have tried. Can someone please tell me what mistake am I doing. In my views.py I am handling a file which produces some results. These results are in the form of a Dataframe(used pandas). From this dataframe I am calculating few integer values which are stored in variables: tot,p,lp,us. I am also getting 3 sub-dataframes namely: dfp,dflp,dfus. I need to display all these on the webpage so I am sending them to an html: uploaded.html as shown below. dict_1 = {'Path':p, 'LPath':lp, 'USig':us} json1 = json.dumps(dict_1) return render(request, 'uploaded.html', locals(), {'js_json1': json1, 'TotVar': tot}) The above code just sends the variables and not the dataframe as I don't know how to do it.

GeoServer and CentOS. Permissions denied when trying to create a layer
I have a Django/Python map application. This application uses gdal library to create geotiffs and tiled layers. Everything works absolutely ok - geotiffs are nicely created, folders with tiles are also created. But there is a problem - I can not create a store and publish a layer, because geoserver says, that it does not have permissions to write to my Django folders. The error message looks like so: '/var/www/django_project/django_project/layers/tiled/test_layer1/0/0.prj', "[Errno 13] Permission denied: And multiple similar error messages. When I check permissions to test_layer1 folder, I see that it is 777 and the owner is apache (not apache tomcat, but apache httpd). I guess the whole problem is in the owner - geoserver for some reason is not able to write to these folders (inspite of 777 permisions). But I'm not sure what owner and what permissions I should set, so that both Django application (or perhaps I should say apache) could write to this folder and GeoServer could read and write to it. By the way, GeoServer is running on top of Apache Tomcat. -
Django : Authenticated differents user models
In my project, I have 2 models named Students and Teachers. These two models are a OneToOne field to User. I have 3 applications : home (index page, faq, about...), teachers (interface for teacher, manage her courses, edit profil ...) and students (interface for students, profil ...) I have one login form (in application home), and I want to use it for log in teachers and students, and redirect to the correct application after authentication. What is the best way for doing that ? I think to create two groups (teachers and students) and assign to the correct group after registration form, and in log in form, just check the group ? PS : Student can create an account, but for teacher, our team creates accounts, so we don't have a registration form for teachers -
Django form not working for ManyToMany (auth.users)
I'm trying to create a Debt model using Django. It has a debtors field which link a debt to many users. It behaves the way I want through Django's administration panel, but I can't get it to work using a django form. I can create debts but the the debtors field is emptying, despite the browser showing an accurate list of users to choose from.

How to test file response in Django?
I have an API that generates and returns a CSV file: def getCSV(): response = HttpResponse(content_type='text/csv') response['Content-Disposition'] = 'attachment; filename='export.csv' writer = csv.writer(response, csv.excel) # ... Write some CSV content ... return response This works fine when I call it from the browser, but I cannot figure out how to write a test that calls the API and check that the CSV contents are what they should be. If I: c = Client() r = c.get('/my/export/api') print(r.content) That just prints three bytes and is most probably conceptually completely wrong. How can I get the contents of the CSV file response in my test? -
