python - Wagtail: accessing data models outside of an app -
very simple really. i'm new django , extension wagtail. want display posts app on homepage, or within other django app matter.
current app structure:
website/home/ website/blog/ website/portfolio/ currently can display posts 'portfolio items' in nice loop on 'portfolio index page'.
when try extend homepage, nothing works.
how access models, etc of 1 app (in case, rendering data 'portfolio items' on 'home'.

you can update context dictionary of homepage page pass latest_portfolio_list template.
class homepage(page): body = richtextfield(blank=true) content_panels = page.content_panels + [ fieldpanel('body', classname="homepage"), ] def get_context(self, request): context = super(homepage, self).get_context(request) context['latest_portfolio_list'] = portfoliopage.objects.live() return context then loop on lastest_portfolio_list in homepage template.
