ImportError: cannot import name 'views' from 'birds_eye'
I've recently started to learn how to build django projects with multiple apps. I have learnt that by using from . import views I can import the different views from the current directory that I am in. However, when using this method, the prompt would give me an error saying: ImportError: cannot import name 'views' from 'birds_eye' The following is my current directory tree of my django project: birds_eye |- accounts (app folder) |- birds_eye (actual project folder) |- clubs (app folder) |- events (app folder) |- posts (app folder) |- static |- templates And this is the actual code of what is happening: birds_eye |- birds_eye (actual project folder) |- urls.py from django.contrib import admin from django.urls import path, include from . import views urlpatterns = [ path('', views.HomePage.as_view(), name="home"), path("admin/", admin.site.urls), path("test/", views.TestPage.as_view(), name="test"), path("thanks", views.ThanksPage.as_view(), name="thanks"), path('accounts/', include("accounts.urls", namespace="accounts")), path("accounts/", include("django.contrib.auth.urls")), # Events --> Calendar, Posts --> Feed | Expected to finish later on. Uncomment when done. # path("posts/", include("posts.urls", namespace="posts")), # path("events/", include("events.urls", namespace="events")), path("clubs/", include("clubs.urls", namespace="clubs")), path('surveys', include('djf_surveys.urls')), ] Is there any solution to this? (I can edit the question in order to provide more resources from my project) -

Django needs to restart server for changing data in template
The goal is to make texts in static templates like "about us" page dynamic with a model so that it can be edited easily later on. My model is as below: class SiteData(models.Model): data_set_name = models.CharField( max_length=200, blank=False, null=False, default="نام مجموعه داده" ) main_page_english_info = models.TextField( verbose_name="مقدمه انگلیسی", blank=True, null=True ) main_page_persian_info = models.TextField( verbose_name="مقدمه فارسی", blank=True, null=True ) my view is as below: class HomePageView(ListView): model = SiteData template_name: str = "core/index.html" site_data = SiteData.objects.get(pk=1) context_vars = { "site_data": site_data, } def get_context_data(self, **kwargs): context = super(HomePageView, self).get_context_data(**kwargs) context.update(HomePageView.context_vars) return context and my template: <p class="mt-3 text-justified text-english fw-semibold nm-text-color" style="direction: ltr; ">{{ site_data.main_page_english_info }}</p> <p class="mt-3 text-justified nm-text-color">{{ site_data.main_page_persian_info }}</p> My problem with this method is two main issues: This method works and if I change data from admin panel, it will be applyed, BUT ONLY if I restarted development server! (ctrl + c and py manage.py runserver). Where is my problem? How can I solve this issue? My model itself isn't so dynamic itself, and this is why I'm also trying another method which I have other problems in that, and I've asked another question here. Now, I'll appreciate an answer to either of these question! -
How to rename default django model field after creation in admin panel
I am making a simple application in Django, where I want my admins to be able to go into the admin panel and create a Level object class Level(models.Model): content = models.CharField(max_length = 200) ^^ This is my simple layout for the model, only admins can create this. However, when my admins create the Level object, it shows up like this: How it shows up in admin panel I don't want this, and I want that to be replaced with the string content, which is a field in my Level model So instead of looking like above, I want it to just contain the context.

Django doesn't show images after adding multiple environments
I'm trying to add local and production environments to my Django project. So instead of one settings.py file, I created a settings directory and in that directory, added 3 settings files: base.py, local.py, and pro.py settings (directory) base.py (the new name for settings.py) local.py (inherits from base.py with some parameter overrides) pro.py (inherits from base.py with some parameter overrides) In the base.py file, I updated the BASE_DIR parameter to point to the parent folder of the current file. previous BASE_DIR: BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) new BASE_DIR: BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath( os.path.join(__file__, os.pardir)))) I didn't change static and media root parameters (in base.py): STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, 'static/') MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media/') However, after the change, my images don't show up anymore.

send variables or messages to page while script is doing tasks (django 4)
I'm doing some python script with django, and I when the user submit a file, I process the file and do tons of tasks, it can last a few minutes. While the user is waiting, I got a loading screen in js, and I print in console what's happening. But I would like to print it in the page, on the loading screen, is there a simple way to do this? my model looks like that models.py def main(): #all the long stuff & logic and my view : views.py def upload(request): #some other stuff MyModel.main() return render(request, 'frontend/upload.html',{ 'form':form, } ) It can be frustrating for the user (and for me) to wait and not know what's going on, I'd like to use my page as I use the console with print, because I'm not over with the stuff to do and I guess it could last some long minutes. -
error while using django_scopes : 'A scope on dimension(s) tenant needs to be active for this query.'
I am using django_scopes module to integrate tenancy across all get views in my django app. As per the readme doc in the repo: https://github.com/raphaelm/django-scopes it says: You probably already have a middleware that determines the site (or tenant, in general) for every request based on URL or logged in user, and you can easily use it there to just automatically wrap it around all your tenant-specific views. Accordingly, I have setup my middleware : class TenantScoper: def __init__(self, get_response): self.get_response = get_response def __call__(self, request): with scope(tenant='xyz'): response = self.get_response(request) return response However, for model view set, when i bring up the server i get an error: django_scopes.exceptions.ScopeError: A scope on dimension(s) tenant needs to be active for this query. class TenantFeatureViewSet(viewsets.ModelViewSet): serializer_class = TenantFeatureSerializer queryset = TenantFeature.objects.all() Although it works perfectly for custom get view: class TenantFeatureView(APIView): def get(self, request): data = TenantFeature.objects.all() Error seems to originate when the line TenantFeature.objects.all() gets executed during server initialisation itself, Is there any workaround for this? -
How to reverse a filter class in Python/Django?
I needed to filter models instances with custom function, and using Post.objects.filter(func) didnt help, I got a type error cause "object is not iterable, so I went with def filter_posts(x): if x.author in followed_author_list: return True else: return False posts = filter(filter_posts, Post.objects.all()) return render(request, 'main.html', {'posts':posts }) And it worked, but now I cant reverse the list, cause I want to order it so newest will be last. If I use list() on it, then posts stop appearing on my website at all, cause I assume its not a different type?.. Question is, how do I reverse filter class, or pull this off in general, so I get my posts filtered in reverse order? -
How do I exclude some File Types from FilerFileField (filer.fields.image)?
I'm working on Django-CMS project. For some models I need to let users upload only these types of files -> .svg, .png, .jpg, .webp (basically for images). The best solution, as I thought, was to use FilerImageField, but it doesn't allow me to upload .svg or .webp. So, what I need to do, is to exclude the possibility of uploading .pdf and other types of files to FilerImageField and allow only for .svg, .png, .jpg, .webp. Would appreciate any kind of help. from cms.models.pluginmodel import CMSPlugin from django.db import models from filer.fields.image import FilerFileField, FilerImageField class MainSection(CMSPlugin): image = FilerFileField(verbose_name="Section Image", related_name="section_image", null=True, blank=True, on_delete=models.CASCADE, help_text="Max file size: 500 kb.
