How to exclude drf router path from drf_spectacular SERVERS setting
I would like to verify some best practices when using drf_spectacular with a django project. I have an API in a django project where all the endpoints use the api/ prefix, i.e. in urls.py, I'm using. path('api/', include('myapp_api.urls')), The myapp_api project'ss urls.py uses the default router, so something like router = routers.DefaultRouter() router.register(r'assets', views.AssetsViewSet) By default, this means that the swagger docs will present all the endpoints as something like... /api/assets/{}/ instead of /assets{}/ This of itself isn't a big deal because the swagger UI's test calls will work just fine because it will correctly call https://example.com/api/assets{}/. It just looks a bit messy in SwaggerUI. The main problem arises when I set the OpenAPI server object, which for drf_spectacular is the SERVERS setting, e.g. SPECTACULAR_SETTINGS = { 'SERVERS': [{'url': 'https://example.com/api'}], } At which point I have failure because the Swagger test calls will try and request to https://example.com/api/api/assets/{}/ and will still show the /api/ prefix on all the endpoints. I seem to have two options: I could go to my urls.py and use path('', include('myapp_api.urls')) instead of path('api/', include('myapp_api.urls')) but that's not desirable because the prefixing seems to make sense in this context. I could use a drf_spectacular preprocessing hook … -

Django transfer database to different Django project without messing up the logic
I built a django project with a few models. Now I created a second server with the same setup. This one is meant to be the deployment server. Databases are seperate from the dev-server. However can you tell me if I can simply copy the databases from the dev server to the deploy or will the django logic, since I also mean the user models and permissions etc. The tables wich I created myself are no problem to transfer to the new server. However I am wondering If django gets confuse when I also transfer something like the auth_user Model. Should this work since I also just copied the backend logic as well? -

Wagtail add thumbnail image to PageChooserPanel
How is it possible to customize the explorer/list view of the PageChooserPanel? I would love to add a thumbnail image here to make life easier for the editors. Their task is to pick out a few dozen artworks (pages) from a large archive. A preview image (and possibly a few additional columns) would greatly simplify this work. I am aware of the get_admin_display_title of a Page as mentioned here. How about a custom version of the PageChooserPanel? I found the AdminPageChooser widget in there, but did not understand how the table of the explorer view is rendered finally. Not sure if it is necessary to get into the weeds to this extend. Would love to see a simple hook like the ModelAdmin list view with its ThumbnailMixin. # wagtail/admin/panels.py from wagtail.admin.widgets import AdminPageChooser class PageChooserPanel(FieldPanel): # ... def get_form_options(self): opts = super().get_form_options() if self.page_type or self.can_choose_root: widgets = opts.setdefault("widgets", {}) widgets[self.field_name] = AdminPageChooser( target_models=self.page_type, can_choose_root=self.can_choose_root ) return opts -

How to Deploy Django App on Centos server having domain secured With SSL?
I have a Django App which I want to deploy on a Centos Linux server having a global/public IP which is assigned to a domain and is secured with SSL. The System configuration is as: centos-release-6-10.el6.centos.12.3.x86_64 Apache/2.2.15 (CentOS) When I run the server using: python manage.py runserver 0.0.0.0:8000, then it is only accessible from the browser by passing a local IP say http://192.xxx.xx.xxx:8000/django_app/home But I want to access it from the public/global IP, but it gives an error when I replace the local IP with Global/Public IP or domain assigned to the public IP as: 105.168.296.58 took too long to respond. Try: Checking the connection Checking the proxy and the firewall Running Windows Network Diagnostics ERR_CONNECTION_TIMED_OUT When I simply put this public IP in the browser as https://105.168.296.58 then it redirects the browser to the app/website say https://mywebsite.com/home which is running at port 80 on Apache, and shows the assigned domain instead of IP, so IP is working fine. in settings.py: all hosts are allowed as ALLOWED_HOSTS = ['*'] Methods tried are: by using django-extensions as: python manage.py runserver_plus --cert certname 0.0.0.0:8000 by using django-sslserver as: python manage.py runsslserver 0.0.0.0:8000 The app runs from both of these methods only locally … -
