I have something like this in my Project#show view:

...
<p>
  <b>Start date:</b>
  <%= @project.start_date %>
</p>

<p>
  <b>End date:</b>
  <%= @project.end_date %>
</p>

<div id="calendar_view">
</div>

And I have the following in my projects.js.coffee:

$ ->
    $("#calendar_view").datepicker({
        inline: true
    })

The thing is, I would like to instantiate the datepicker with some relevant information ( such as the span of the project in months, restrict it to the beginning and end of the project ). Is there a way to mix some ruby, or the actual project’s data inside the coffeescript?

    For my projects, I typically add an additional yield block to the end of our documents, right before the closing body tag.

    <body>
...
<%= yield :additional_javascript %>
</body>

    This way, in views, I can append less obtrusive JavaScript to the end of the document via a content_for :additional_javascript block:

    <p>
  <b>Start date:</b>
  <%= @project.start_date %>
</p>

<p>
  <b>End date:</b>
  <%= @project.end_date %>
</p>

<div id="calendar_view">
</div>

<% content_for :additional_javascript do %>
  $(function () {
    $("#calendar_view").datepicker({
      some_property: <%= @project.some_property %>,
      inline: true
    })
  });
<% end %>
