Question

I would like to pass a parameter through a link_to method in Rails. I know there is a way to do it via the URL but I really don’t want to do that. Is there any way to pass a param via a link without adding it to the link itself?

I know in PHP you can post and then retrieve that value by using the post variable. Is there something similar in Rails?

Answer 1

link_to signature looks as follows:

link_to(body, url_options = {}, html_options = {})

So, POST would look like (lets say you want to POST user’s data):

link_to "Link text", some_path(:foo => "bar", :baz => "quux"), user: @user, :method => :post

User’s data can be retrieved in the controller using params[:user]
