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 … -
