Rails - Passing parameters to create filled in form

Question

I want to pass some parameters with link_to method to create method, so that the form will shown prefilled to a user.

I wrote this code to pass the parameters,

<%= link_to "Buy", new_transaction_url(:friend_id => @friend.id, :t_type => 2) %>

And in transactions_controller's new method, I have:

@transaction = Transaction.new
@transaction.t_type = params[:t_type]

It didn't work as well.

That would be great if you can help me.

Thanks.

Usually new_transaction_url would call the #new action in your controller, not the #create action. Watch your log file while you do it to see exactly what controller action is being called and what parameters are being passed.
