Ramaze help

[Jeff Nixon]

I want to conditionally display content in a view based on a session variable. I'm not clear at this stage if there is a built in template language that would allow me to use conditional statements. Below is my first stab at the controller and view code. Can you point me in the right direction for documentation or examples? Any insight is much appreciated.

controller/presentationtest.rb:

class PresentationsController < Ramaze::Controller

map '/presentations'

  def authenticate(password)

  if password = 'ammpresentations'

  session[:logged_in] = true

  end

  end

end

view/presentations.xhtml:

<p>

Please login below to view the Presentations. 

</p>

<form action="#{PresentationsController.r(:authenticate)}" method="POST">

    <label for="password">Password</label>

    <input type="password" name="password" />

    <br /><br />

    <input type="submit" value="Login" />

</form>

<!-- conditional check goes here; logged_in = true -->

// here is the content that will be displayed, once you enter password //

<a href="#" >Presentation 1</a><br>

<a href="#" >Presentation 2</a><br>

<a href="#" >Presentation 3</a> 

<!-- end of conditional section -->

Jeff,

Using the default template engine (Etanni) you can put arbitrary Ruby
code in your views using the following two tags:

* #{}: evaluates the Ruby expression and displays the value
* <?r ?>: used for statements such as "if", loops, etc

In your case this means you can do something like the following:

<?r if session[:logged_in] ?>

<p>This will only be displayed if you are logged in.</p>

<?r end ?>
