Use Vue components in application at runtime
I am developing a small application using Vue which will have list of downloadable components available to the user. Downloadable components will be hosted somewhere on the webserver(compiled version of SFC's) seperately. List of components can be increased or decreased based on users permissions. This application will be shared with the user to download the components of their choice and add them to the list. Problem is am not getting any examples in the internet where compiled components are used inside compiled Vue apps at runtime. All the available examples need compiled components to be registered or to be imported in the applications in order to use it. The only way right now is to chuck the idea of using ES6 or (.vue) Single file Components luxury and use ES5 version which i don't want to. Can anyone help me out? Backend used is Django -
Django: How to realize App structure for specific program (picture)
I'm new to Python/Django and I would like to rewrite an old program as a web application The picture is a screenshot of the program. As you can see there are multiple tabs on the left and two on the top (marked red) so the programm ist kind of nested(?). All of the Tabs work together to calculate the end result. Im kind of overwhelmed so my first question is how to structure the Programm in Django using apps. Is each Tab one app and I link them all together? Also is there a template for tab-style menue? Thank you very much, hope ich can get it realized :D Programm_Image -
Design pattern of coupling/decoupling two apps in Django
I have two apps: app1 and app2. =>app1 has model A gets data with timestamps. =>app2 has model B with some computations that have to be made on the data that model A gets Usecase:. Every time we create model B, it has to check if we have enough data in model A => do an update. This same update is triggered every time we add data to model A. => My design is: since updates are having a place in model B then I import my model A in it and check if I have enough data while creating model B. on the other way around, if I add data to model A I prefer not importing model B in model A to avoid app circular dependencies and coupling. So my idea here is to send a signal from model A to model B and proceeds to the update, is it the best way to do it or you would think of some different design patterns? => I also read on some blogs that using signals is not always suggested, what's your take on this? -

Django unit test remove Files created inside the tests
I'm using DRF view tests. Inside my tests I create files which I want to remove after the tests were running. I'm using addCleanup inside my setUp method to remove the directories. It basically works, but when I run my complete set of unit tests one dir won't be deleted (I think it's the first one created). Here is the relevant code: class BaseViewTest(APITestCase): client = APIClient() base_media_root = settings.MEDIA_ROOT def setUp(self): settings.MEDIA_ROOT = tempfile.mkdtemp(dir=self.base_media_root) # add test data self.addCleanup(shutil.rmtree, settings.MEDIA_ROOT) -
Django {% if object.foreignkey %} returns the opposite of the value
So I have two models. First one is Collection Title and second one is Title Status. In Title Status I have a foreignkey named collection_title_status that points to CollectionTitle. I have rendered the form TitleStatusForm inside my collection_title_detail.html with a DetailView and a FormMixin. The form is in a modal. Globally, this part works, meaning that I can fill the form, and it saves the data and creates a link between the Collection Title and the Foreign Key of Title Status (for example, if CollectionTitle id is 61, my collection_title_status value will be 61 as well). What I want to do : If Collection Title is not linked to a Title Status (meaning the user as not initiate the Status monitoring yet), then I want to display the button called 'Initiate' that opens the modal containing TitleStatusForm to initiate the Title Status model If Collection Title is already linked to a Title Status (which should be done after fulfilling the first step above), then I don't want to display the above mentionned button and modal. Instead, I want to display the values previously entered by the user for each field. So here is how I tried to do it : … -

current path didn't match in django
I am a beginner for django. I tried to make my 1st project helloworld, with the help of tutorials I installed and followed their instructions. When I run my project in server it shows an error 404, the current path didn't match any of these. myproj/urls.py from django.contrib import admin from django.urls import path from helworld.views import hello urlpatterns = [ path('admin/', admin.site.urls), path('index/', hello), ] helworld/views.py from django.shortcuts import render from django.http import HttpResponse def hello(request): return HttpResponse(request, "hello world!") This is my code when I run it. Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/helworld Using the URLconf defined in myproj.urls, Django tried these URL patterns, in this order: admin/ index/ The current path, helworld, didn't match any of these. You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page. I searched for solution but being a beginner its bit tough for me to solve this error. so kindly help me with an easy clarification. Thank you in advance. -
