Changes: * Make it so you can click or hover over a post's favorite count to see the list of public favorites. * Remove the "Show »" button next to the favorite count. * Make the favorites list visible to all users. Before favorites were only visible to Gold users. * Make the /favorites page show the list of all public favorites, instead of redirecting to the current user's favorites. * Add /posts/:id/favorites endpoint. * Add /users/:id/favorites endpoint. This is for several reasons: * To make viewing favorites work the same way as viewing upvotes. * To make posts load faster for Gold users. Before, we loaded all the favorites when viewing a post, even when the user didn't look at them. This made pageloads slower for posts that had hundreds or thousands of favorites. Now we only load the favlist if the user hovers over the favcount. * To make the favorite list visible to all users. Before, it wasn't visible to non-Gold users, because of the performance issue listed above. * To make it more obvious that favorites are public by default. Before, since regular users could only see the favcount, they may have mistakenly believed other users couldn't see their favorites.
Helpers
This directory contains helper functions used by views. Helpers are used for simple common functions, such as linking to users or formatting timestamps.
Helper functions are globals. If you see an unnamespaced function in a view, and it's not a Rails function, then it's probably a helper defined here.
All helper functions defined in this directory are globally available to all views. They're not limited to single views. For example, the functions in posts_helper.rb are available to all views, not just to app/views/posts.
The use of helper functions should be minimized. Partials or components are preferred for more complex widgets, or for things used in only one or two places. Helper functions should be limited to very simple things used in nearly all views.
