A Hashrocket project

`disable_with` to prevent double clicks

If a link or button initiates a request that takes a long time to respond then the user (being a user) might click the link or button again. Depending on the code implemented on the server this could put the application into a bad state.

Rails has a handy feature that will disable a link or button after the user has clicked it, disable_with:

<%= link_to('something',
      something_path(something),
      data: {
        disable_with: "Please wait..."
      }
    )
%>

In Rails 5.0 and up sumbit buttons have disable_with set by default. To disable disable_with use:

data: { disable_with: false }
