I'm using this tutorial to set bootstrap modal content in forms, but I want to set the title...
I think I don't understand how to set the title content_for method...I understand it for templating, but if I want to send a title to the modal, is it best to make a helper for that? Is there a better Rails 4 way to do this?
Please advise, and remember, I'm not a CE--I've looked at the rails doc and google searched, so please don't demean my question by posting a google link. Thanks!
If you're going to be rendering the title of the modal dynamically, it's typically better to use a helper method. This will keep your view logic DRY and readable. This method will accept an argument for the title and if none is present it will render a default title.
In application_helper.rb:
def modal_title(title)
if title.empty?
"My Default Title"
else
title
end
end
In your modal partial where the title should appear:
<%= modal_title(yield(:title)) %>
In the view, you will have access to dynamically set the title using content_for. For example, you could pass a string as your title or pass an instance variable from your controller.
<% content_for :title, @your_variable %>
