Fix favorite star on community home - Generating context with group for the org page

Fix #1632 (closed)

Issue description

Clicking on the star in community home header (e.g. https://gitter.im/viktomas-godu) doesn't result in adding group to favourites. This is caused by group being missing in window.troupeContext and consequently in backbone model. more in #1632 (closed)

Root cause and description of the fix

The the org renderer uses uses basic context as a tropueContext this context contains only user information. So when it gets serialized and then in the browser populates the backbone model, the whole group set of information is missing. This didn't cause more severe trouble because everything on the page gets rendered on the server.

Fix has been implemented by extending basic context with serialized group as a part of the cleanup the org renderer now uses troupeContext.group instead of serializing it again

Manual testing

  • I've tested that the star button works as expected
  • I've touched twitter share URL so I tested that the share button still has correct group URL

Endnote

This MR took me all the way from UI view events to the express routes on the server. It was a long journey but I've learnt more about:

  • Backbone model and collections
  • Server side vs client side rendering
  • troupeContext and sanitizing mongoDB entities
