<%= link_to controller: "pages", action: "ajouter", id: n %>

But your code is otherwise so messed up that I can't tell exactly what you're trying to do. What is the "do" at then end of the call to link_to? Is the <%end%> after </button> intended to be associated with it? Or is it supposed to be for the @defautrec.each, but is just in the wrong place?

I suspect you're trying to wrap a button in a link, but that's not how HTML works, regardless of whether you're using Rails or not. Do you just want a button that acts like a link??? It that's the case, you want button_to:

<http://stackoverflow.com/questions/6247491/rails-3-display-link-as-button>

Anyway, you cannot just stick "do" at the end of a function call in order to start a loop. Remember, <%= %> just executes the Ruby code inside and inserts the result into the HTML, and this is not legitimate Ruby:

link_to controller: "pages", action: "ajouter" do

Or, for more clarity, since this is the way it would be parsed:

link_to (controller: "pages", action: "ajouter" do)
