FAQ

How do I find the Rails route for a page?

Check the 'page' data attribute

The easiest way is to type the following in the browser while on the page in question:

document.body.dataset.page

Find here the source code setting the attribute.

Rails routes

The rake routes command can be used to list all the routes available in the application, piping the output into grep, we can perform a search through the list of available routes. The output includes the request types available, route parameters and the relevant controller.

bundle exec rake routes | grep "issues"

modal_copy_button vs clipboard_button

The clipboard_button uses the copy_to_clipboard.js behaviour, which is initialized on page load, so if there are vue-based clipboard buttons that don't exist at page load (such as ones in a GlModal), they do not have the click handlers associated with the clipboard package.

modal_copy_button was added that manages an instance of the clipboard plugin specific to the instance of that component, which means that clipboard events are bound on mounting and destroyed when the button is, mitigating the above issue. It also has bindings to a particular container or modal ID available, to work with the focus trap created by our GlModal.
