renaming file when uploading with django modelform

Django 2.2 multiples schemas en postgresql
Estimados buenos días. Les hago una consulta. Tengo un sistema el cual da servicio a muchos negocios iguales y cada negocio tiene su schema en postgresql. El tema es que tengo la tabla users donde le agrego un campo que se llama schema que es donde detallo a que schema tiene que ir cada usuario. Este campo lo levantaría en session y cuando llamo al modelo quiero decirle que me traiga los objetos pero de tal o cual schema. Esto seria en tiempo real. Otra cosa en settings.py solo tendría la conexión a la única DB que es donde tendría todos los schemas. Se les ocurre como puedo hacer?, como le digo al medelo que traiga por ejemplo a contactos pero de tal o cual schema Gracias -

I keep staring at this and no joy. My urls.py file. All of the files are displaying except 'display_maintenance.html' from django.contrib import admin from django.urls import path, include from example import urls as example_urls from example import views as example_views urlpatterns = [ path('admin/', admin.site.urls), path('', example_views.home, name="home"), path('add_location', example_views.add_location, name='add_location'), path('add_device', example_views.add_device, name='add_device'), path('add_maintenance', example_views.add_maintenance, name='add_maintenance'), path('display_maintenance', example_views.display_maintenance, name='display_maintenance'), path('device_list', example_views.device_list, name='device_list'), path('search_device', example_views.search_device, name='search_device') ] Here's the views.py where the error is hanging on the return render: def display_maintenance(request): maintenance = Maintenance.objects.all() context = {"maintenance": maintenance} for item in maintenance: item.devices = Devices.objects.filter(maintenance=item) return render(request, 'example/display_maintenance.html', context) And finally, the html file. I'm baffled: def display_maintenance(request): maintenance = Maintenance.objects.all() context = {"maintenance": maintenance} for item in maintenance: item.devices = Devices.objects.filter(maintenance=item) return render(request, 'example/display_maintenance.html', context) -
What method to choose for designing the study on Amazon Mechanical Turk?
I would like to choose a method for psychological study design, which I want to implement in Amazon Mechanical Turk. The experiment requires dragging and dropping images and some specific randomization, so I can't use platforms like Qualtrics or SurveyMonkey (I think I can't). So I want to create my own experiment and put it on a server. I would use Django and PsychoPy package, but I'm afraid Django is overcomplicated for such a project (I want to have just a csv or a json file with participants' data as output). The second idea is just a javascript, but I feel more comfortable in python. What is your advice? Maybe there is a better option? Thanks for answers. -
Why am I not being able to save my addresses?
Hi I'm trying to develop an e-commerce website with django. I want to use ajax to handle my checkout form. When I added Ajax, after filling out the form and clicking the submit button, I am seeing that my form and data is not getting saved by going into my admin. It's also not being redirected to return HttpResponseRedirect(reverse(str(redirect))+"address_added=True"), rather it's being redirected to http://127.0.0.1:8000/checkout/?csrfmiddlewaretoken=u6hDPBVuOZbDmoHvRFWb2PvfK1YamCIKGSaDkKdVTviWvJODgY5lM6rKppoW1oeP&address=123+Main+Street&address2=&state=MA&country=USA&zipcode=55525&phone=%28877%29+314-0742&billing=on.Can anyone please help me out with what's actually wrong?

How to use Django's include without a string literal?
I just started up with django. Following this tutorial, I ended up with the following urls.py: from django.contrib import admin from django.urls import include, path urlpatterns = [ path('polls/', include('polls.urls')), path('admin/', admin.site.urls), ] This links to polls.urls.py which has its own router. The part I don't like is the string literal 'polls.urls' which is, well... a string literal. I would like to somehow reference the file directly using some of python's power, and have AT LEAST my IDE protect me. What happens if I want to move that polls.urls.py file, or rename it, or rename polls? Should I trust my IDE to catch a reference from a string literal? This is almost like doing this monstrosity, and is very hard for me to accept as the best practice. It just seems odd to me. Is there a way to use something less prone to errors than string literals in django's routers?
