Rails - Ability to Enable/Disable Links on a View?

I have a UserMailer View that has several link_to's like so:

<开发者_开发问答%= link_to('XXXXXXXX Link Title', item_url(@item, :only_path => false), :style => 'color:#5196E3;text-decoration:underline;') %>

The page has several different links. I'd like to know if there is a way to globally set in the view to enable or disable the links.

If enabled, the above would run like normal, if not the block above would just show the text (XXXXXXXX Link Title) and not be linked?

Any ideas other than wrapping every link_to inside a IF statement?

Thanks

Rails already provides a link_to_if helper...

So, define @some_boolean in the controller class, or if you want a true global, then set $some_boolean appropriately. Then use the link_to_if :

<%= link_to_if(@some_boolean, "Link Title", <url etc..>) %>

Documentation

you can create a helper method that takes your link parameters and returns the value that you want. which means you will only implement one IF statement.(which will be in the helper.)

great comment by Sean Hill: helpers should be in helper files :)

ApplicationHelper:

helper_method :conditional_link

  def conditional_link(string,url)
    if true_condition
      return link_to string, url
    else 
      return string
  end

in your view:

<%= conditional_link string, url %>

if also want else part if condition not true then use this

<%= link_to_if( some_boolean, "Link Title", <url etc..>) { link_to "link title", <url etc..>} %>

remember if you wont use code block then text will appear and if u want to render link in other style in case of false then use code block.
