How to create key to get a request to Django API?
I am creating a database with Django, and I am accesing it with Excel and Apps Script. I can't log in into my superuser account (the only account I'll be having). Therefore, I want to know if there is a way to set a key, or a password, passed through an HTTP header, that I can use to access my API. Currently I only have one API get method, but I'll have more create, update, etc., and I want to be able to use the same key for these as well. It is a really simple Django application deployed in heroku, so I am not using django-REST-framework, nor graphene-django. So if the solution can come without installing anything else, it would be nice. However, if this is not possible, it is better if the solution comes through graphene-django, since I have used it before, and I am more familiar with it. It is important to notice that both the excel file and the apps script are private, since I am using django as a database manager for a small, personal project. Thank you very much in advance! -
How do i change what django looks for in .filter()?
take this example code: from .models import Employees filters = { "name" : request.GET.get("name"), "work_place" : request.GET.get("work_place_filter") } for index, item in enumerate(filters): key = list(filters.keys())[index] value = filters[item] flykninger = Employees.objects.filter(key = value) what im trying to do here is to change what key the filter() function compares the value to if the input fields are not None. But whenever i try to run my own code that includes this snippet, i get Cannot resolve keyword 'key' into field. Choices are: alder... How do i do this? is there another way to do it that i'm not aware of? Thanks -
Is it possible to edit the page_obj before passing template?
I can catch <class 'django.core.paginator.Page'> in get_context_data function of django view class. What I want to do is alter the showing item and get it back to <class 'django.core.paginator.Page'> again. django.core.paginator.Page source code is here. https://docs.djangoproject.com/en/4.0/_modules/django/core/paginator/ I found it has object_list,so I try to change def get_context_data(self): temp = super().get_context_data() print(type(temp['page_obj'])) #<class 'django.core.paginator.Page'> new_object_list = [] for t in temp['page_obj'].object_list:## I can iterate the item here. # make new_object_list here temp['page_obj'].object_list = new_object_list print(temp) # nothing changes return temp However object_list doesn't change. -

If you see the 'urlpatterns' variable with valid patterns in the file then the issue is probably caused by a circular import
i got:django.core.exceptions.ImproperlyConfigured: The included URLconf '<module 'bookstore.urls' from 'C:\blog\bookstore\urls.py'>' does not appear to have any patterns in it. If you see the 'urlpatterns' variable with valid patterns in the file then the issue is probably caused by a circular import. my urls.py in blog is: from django.contrib import admin from django.urls import include, path urlpatterns = [ path('admin', admin.site.urls), path('' , include('bookstore.urls')) ] my code in view.py is: from django.http import HttpResponse from django.shortcuts import render def home(request): return HttpResponse('Home Page') def users(request): return HttpResponse('users Page') def info(request): return HttpResponse('info Page') my code in bookstore.urls.py is: from django.urls import path from bookstore import views URLPatterns = [ path('home/' ,views.home), path('users/' ,views.users), path('info/' ,views.info), ] and thank you for your help -

Django Stripping Blanks In Between Words When Generating Blanks
I am working on a Hangman game using Django and I'm having some trouble generating the blanks from the words if the answer is two words, such as a first and last name. It seems to be something with Django stripping spaces and I have tried playing around with some solutions I found elsewhere, but unsuccessfully. Here I've changed admin.py1 Here I've created a fields.py 2 Where I probably am lost is how I'm linking it back in models.py or displaying it in the template. My logic is solid, I can replicate outside of Django, so it is something model related. Any help or guidance would be greatly appreciated! -

Why is Django is not loading my template view but it once was
My view was running fine until Ill tried to override an admin view. Which i eventually got to work. However in the process I broke the path to my view that was working. The admin view had nothing to do with my originally working view. Now I copied my view into every possible level of my project structure. Yet the django template loader fails to find my order_input.html The error shows the correct path to my order_input.html. I made copies of order_input.html at every single possible level of my project... but django still cant find it. APP - URLS.PY from django.conf.urls import url from . import views urlpatterns = [ url(r'^hw/$', views.helloworld, name='helloworld'), url(r'^order_input/$', views.order_input, name='order_input'), url(r'^time/$', views.today_is, name='time'), url(r'^$', views.index, name='index'), ] SETTINGS.PY # Application definition INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', # 'django.contrib.staticfiles', 'import_export', 'hw_app', ] PROJECT URLS.PY urlpatterns = [ url('r', include('hw_app.urls')), url('admin/', admin.site.urls), path('clearfile', views.clearfile), path('readfile', views.readfile), path('writefile', views.writefile), path('helloworld', views.helloworld), path('order_input', views.order_input), path('ajax_view', views.ajax_view), ] -
How do I use start-app template context in a template file?
I have the current setup for a Django app template which I pass to start-app like so: python3 manage.py start-app --template template/ myapp With a directory structure like this: template/ templates/app_name/ page.html ... app.py app.py uses the template context passed when start-app is run, and works fine! # app.py from django.apps import AppConfig class {{ camel_case_app_name }}Config(AppConfig): default_auto_field = 'django.db.models.BigAutoField' name = '{{ app_name }}' However, I'm trying to get similar behaviour out of page.html, to no avail. {% extends "{{ app_name }}/otherpage.html" %} {% block content %} <p>Hello from {{ camel_case_app_name }}!</p> {% endblock %} If I run start-app like normal, the template is copied over and the app name is not inserted. If I try to run start-app with --extension py,html I don't get the expected behaviour either, because the template is rendered. Is there a way to convert the {{ app_name }} calls in page.html without attempting to render the entire template? -

Django synchronous function: wait for one session to finishing using function
In my django server, I have a function that handles a request from a user. When multiple users are sending requests from within their respective sessions at the same time, the function processes the requests within their own sessions so it happens in parallel. But I want to ensure that when I have multiple requests from multiple users, they are handled one by one rather than simultaneously. Basically, I don't want this function to be a session instance but a global function that only one user can use at a time. How can I solve this problem? This is an open-ended question so as long as we are using Django in the implementation I don't have any more constraints. -

Django-cart object always empty
I am developing ecommerce web application using Django. After I have implemented a footer, pagination and a search bar, "Add to cart" button stopped working.

How to change display value for one to one field in django admin?
I'm looking to change the display value for a one to one field in the django admin dashboard. I want to prefix the user's name to the one to one field. I'm able to successfully do it for a foreign key like this: def formfield_for_foreignkey(self, db_field, request, **kwargs): if db_field.name == 'audio_module': return AudioModuleChoiceField( queryset=AudioModule.objects.filter(is_deleted=False).order_by('user__last_name') ) return super().formfield_for_foreignkey(db_field, request, **kwargs) However, I don't see any options in the docs to override a formfield_for_onetoone. Currently, my form field looks like this: audio_module has a FK to my user table. Like I said above, I'd like to prefix the user's name in front of the audio module in the dropdown so it'll be easier to identify audio modules for specific users. i.e. John Doe - audio module 2 How do I achieve this? -
