Remove a parameter from URL

Question

I have a link_to method in my Rails app:

link_to t('edit'), edit_building_path(@building, :hidden_action => params[:action])

How do I remove hidden_action from url?

Currently url looks like:

http://localhost:3000/buildings/2/edit?hidden_action=new

My issue is that I need to know from which page user is accessing this link_to.

Answer 1

In rails helper, it depends on you

def edit_the_building_url(building, you_want_the_params_or_not)
  if you_want_the_params_or_not
    edit_building_path(building, :hidden_action => params[:action])
  else
    edit_building_path(building)
  end
end

then in your controller

link_to t('edit'), edit_the_building_url(@building, true)

or

link_to t('edit'), edit_the_building_url(@building, false)

if above doesn't profit you, just

url = url.chomp("?hidden_action=#{params[:action]}")
