Fix an exception on the error page when a controller index action raised an PG::AmbiguousColumn error because the model `search` method generated SQL with an ambiguous column reference. In this case the error page tried to generate data attributes for the <body> tag, but this failed because evaluating the `current_item` raised an exception again.
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.
