<%= link_to          


        

Answer 1

Below is the code if you want to preload the modal on the page in hidden state

<%= link_to "Open modal", "#my-modal", :class => "btn", "data-toggle" => "modal" %>
<div class="modal hide fade" id="my-modal" title="My modal">
  <div class="modal-header">
    <button aria-hidden="true" class="close" data-dismiss="modal" type="button">×</button>
    <h3 id="myModalLabel">Modal header</h3>
  </div>
  <div class="modal-body">
    Modal Body
  </div>
  <div class="modal-footer">
    <button aria-hidden="true" class="btn" data-dismiss="modal">Close</button>
  </div>
</div>

And if you want to load the modal through ajax then you can do something like this

<%= link_to "Open modal", new_post_path, :class => "btn", :remote => true, "data-toggle" => "modal", "data-target" => "my-modal" %>
<div class="modal hide fade" id="my-modal" title="My modal">
  <div class="modal-header">
    <button aria-hidden="true" class="close" data-dismiss="modal" type="button">×</button>
    <h3 id="myModalLabel">New Post</h3>
  </div>
  <div class="modal-body a-unique-class">
    New Post Body
  </div>
  <div class="modal-footer">
    <button aria-hidden="true" class="btn" data-dismiss="modal">Close</button>
  </div>
</div>

In posts/new.js.erb you would include

$(".a-unique-class").html('<%= j render "posts/_form" %>')

Make sure that you have a unique id or class for every modal body.

Assuming you want to create a new post using modal form, the controller code and _form.html.erb is in place

There is a syntax error in benchwarmer's answer above.

try this instead:

$(".a-unique-class").html('<%= j render "posts/form" %>')

Answer 3

There is a prettier way to add data attributes in Rails. You can do something like this to get the same results.

<%= link_to 'Click Here', "#", data: {toggle: "modal", target: "#modal"} %>
