Question

I have an AuditLog with things like id, action, type, description…

What I’d like to do in the view is something like:

case description
  when "created"
    <li>created styling</li>
  when "deleted"
    <li>deleted styling</li>
  else
    <li>error</li>
end

Trying to learn how to do this in a view and the correct syntax, which the resources I found on Google don’t specify.

Answer 1

If your styling contains lots of tags and HTML elements, I would suggest putting them into partials:

<%= render :partial => @audit_log.description rescue nil %>

If you description is created, then it would render the file _created.html.erb in the same folder as the current view

If it is deleted, render _deleted.html.erb automatically.

If description is something else, which has no _something.html.erb file, then nothing would be displayed (without rescue nil, error will occurs)

======

If you want to render the partial in some different folder,

<%= render :partial => "some/where/#{@audit_log.description}" %>
