Django URL patterns to serve external webpack bundle
I'm writing a django rest framework API (backend) with a react SPA frontend. For the production environment, the front end is served up via nginx at http://example.com/ and the backend is proxied to gunicorn and served from the same domain with a different path - http://example.com/api/ This is all working fine in production, there are no CORS issues as the frontend and backend are both served up under the same domain via nginx. For local development, I want to be able to replicate a similar setup using ./manage.py runserver and have django serve up the frontend from project/frontend/dist (built by npm build seperately). Has anyone got any urlpattern wizardry that will allow this to happen and also let the react-router play nicely? I just can't figure it out and it's starting to drive me nuts... The project structure is something like this if it helps in any explanations. Project | ── backend │ ├── apps │ ├── config | | ├── settings.py | | ├── settings_local.py | | ├── urls.py │ ├── manage.py │ ├── requirements.txt │ └── venv ├── frontend │ ├── dist (contains the npm build webpack) │ ├── node_modules │ ├── package.json │ ├── package-lock.json │ ├── … -

django staticfiles collection error
I started a new project in django and created a development and a testing environment with their settings in the same folder as the custom settings.py everything is going well till I created a static file directory and I tried to collect static files but got error. raise ImproperlyConfigured("You're using the staticfiles app " django.core.exceptions.ImproperlyConfigured: You're using the staticfiles app without having set the STATIC_ROOT setting to a filesystem path. this is my directory BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) if DEBUG: MEDIA_URL = '/media/' STATIC_ROOT = os.path.join(os.path.dirname(BASE_DIR), "static", "static-only") MEDIA_ROOT = os.path.join(os.path.dirname(BASE_DIR), "static", "media") STATICFILES_DIRS = ( os.path.join(os.path.dirname(BASE_DIR), "static", "static"), ) -
Django ORM - MySQL query count optimization for related models
I have two related models, that looks like below: class Enterprise(models.Model): id = models.AutoField(primary_key=True) subsystem_id = models.IntegerField() name = models.CharField(max_length=255, unique=True) modif_date = models.DateTimeField(auto_now=True) active = models.BooleanField(default=True) class Project(models.Model): id = models.AutoField(primary_key=True) subsystem_id = models.IntegerField() name = models.CharField(max_length=255) modif_date = models.DateTimeField(auto_now=True) enterprise = models.ForeignKey('Enterprise' on_delete = CASCADE) active = models.BooleanField(default=True) In my view, need to get all active Enterprises and list them. I'm doing it this way: enterprise_list = Enterprise.objects.annotate(project_count=Count('project')).filter( Q(active=True) | Q(subsystem_id=-1), project_count__gt=0 ) serializer = EnterpriseSerializer(enterprise_list, many=True) Then, my serializer is displaying project list with some additional query: class EnterpriseSerializer(serializers.ModelSerializer): id = serializers.IntegerField(required=False) name = serializers.CharField(max_length=255, required=False) project_list = serializers.SerializerMethodField() def get_project_list(self, enterprise): project_list = Project.objects.filter(Q(active=True) | Q(subsystem_id=-1), enterprise=enterprise) serializer = ProjectSerializer(project_list, many=True) return serializer.data class Meta: model = Enterprise fields = ('id', 'name', 'project_list') This code is working fine, but it has very serious issue - performance. The first query for Enterprise returns list of ~1500 object. Then, for every object, serializer executes single query to fetch additional data for project which results to ~1500 queries. I've tried prefetch_related and select_related but either I'm doing something wrong or it doesn't work in my case. In the other hand I can get list of project first. This could … -

Django CSS takes time to refresh
When I make a change in css, it takes time to be seen in browser. Often I just leave it and get back to do some backend stuff and while I'm doing that, suddenly and unexpectedly, the css changes are applied. I have seen some solutions on the internet, like clear browser's cache, but it doesn't work every time. What is the reason behind it? It gets annoying when you want immediate results. -
already made a website, now i need it to convert it into an android/ios app
i've been learning and building websites for 5 months. Currently i use js (angular2); html5 css(foundation); and python (django).I've already created a basic website [blog] and considering turning it into an app {android / ios} native apps isn't in my interests (the development takes too long, ecspecially when i have to learn java AND swift). So, i am taking "the hybrid app" approuch. i've read that foundation doesn't work well with ionic (the framework i want to use).the reason i am using ionic instead of foundation for apps is because ionic gives far more acsess to mobile features (bluetooth, photo, data, etc). i read that servers that work for desktop aren't good with moble applications. here are my questions: how do i convert a website into an app? since i can't use foundation and ionic at the same time, do i create a seperate project where i use ionic instead of foundation? then if my app and my website files are seperate, do i have to make seperate servers and one database(i will use database mirroring) or connect them to one server? if i connect them to one server how do i handle mobile requests from desktop ones? -

Django transfer files from local host to web server
I am very new to Python, just did a tutorial on it where I created a small website with a blog. It works fine on the local host http://127.0.0.1:8000/ but when I want to upload the files on my subdomain I created on siteground, my browser then tells me "No matching DirectoryIndex". So I added "Options +Indexes" into the .htaccess. Now I can see the directory "Index of /" and the list of my files when I go the website, Instead of the actual website like I can when using the local host. Is there anything I am missing? Thanks! What I get when I enter the website in my browser on the URL of my subdomain: -

What is a strategy of deploying Django + Vue with docker?
I don't fully understand how should I build and deploy the docker container with my app. I have an app which has two parts - REST API with Django REST Framework and SPA with Vue.js. API is connected to Postres. The question is, should I build a single container where I install SPA, API and database, or have app-container linked with a separate database container. I plan to build containers with gitlab ci and deploy to heroku. Or what is the best practice? -
