How to pass params parameter through link_to?

Question

In Controller

class FeedEntriesController < ApplicationController
  def index
    @search = FeedEntry.search(params[:is_star])
    @feed_entries = @search.page(params[:page])
    @app_keys = AppKey.all
  end
end

In View - feed_entries/index.html.erb

<%= link_to "Stared", {:controller => "feed_entries", :action => "index", :is_star => false } %>

feed_entries table contain is_star:boolean attribute. So, I just want to pass the parameter is_star == true into the params[:is_star].

But the above code is not working. Please some one help me.

If, I click the Stared link. I am getting error like below in the browser:

undefined method `stringify_keys!' for "false":String

you should probably include the stacktrace for your error - my guess, it is coming from inside the FeedEntry#search method? — house9

Could you post the routes associated with the FeedEntries controller? — Marcelo De Polli

It looks like your FeedEntry#search method expects an argument that responds to #stringify_keys! methods, so I assume you should pass a Hash :

@search = FeedEntry.search(is_star: params[:is_star])

BTW link_to with 'controller' and 'action' options is old and verbose syntax, you should use a resourceful style:

link_to 'Stared', feed_entries_path
