Rails 4 Params not passed to the controller from the form -

i using form "get" method. created text field (in testing.html.erb) user enter name. want name passed controller , based on name, want retrieve data database through query. problem here not getting instance variable in controller action (nothing printed on screen when display @testing in "testing.html.erb"). below routes.rb file.

   rails.application.routes.draw   resources :users    # priority based upon order of creation: first created -> highest priority.   # see how routes lay out "rake routes".    # can have root of site routed "root"   # root 'welcome#index'    # example of regular route:   'index' => 'users#index'   'testing' => 'users#testing'   # example of named route can invoked purchase_url(id: product.id)   #   'products/:id/purchase' => 'catalog#purchase', as: :purchase ..... 

this testing.html.erb file

<h1> testing page </h1>   <%= form_for users_path, :url => {:action => "testing", :name => :name}, :html => {:method => :get} |f| %> <%= f.label :first_name %><br />     <%= f.text_field :name %><br />           <%= f.submit "view schedule" %> <% end %>  <%= @testing %> <%#= @testing.email %> <%#= @testing.content %> 

please note commented @testing.email/content in above file supress error (undefined method `email' nil:nilclass).

below users_controller.rb file.

class userscontroller < applicationcontroller   before_action :set_user, only: [:show, :edit, :update, :destroy]   #before_action :user_set, only: [:testing]   # /users   # /users.json   def index     @users = user.all     @test = params[:name]     @test_index = params[:age]   end    # /users/1   # /users/1.json   def show   end   def testing     @testing = user.find_by(name: params[:name])     #if @testing.name == "siri"         # #render text: "hello #{@testing.name}"         #redirect_to action: :index     #end  end .........   private     # use callbacks share common setup or constraints between actions.     def set_user       @user = user.find(params[:id])     end      # never trust parameters scary internet, allow white list through.     def user_params       params.require(:user).permit(:name, :email, :content)     end end 

the log-file shows following.

processing userscontroller#testing html   parameters: {"utf8"=>"✓", "/users"=>{"name"=>"hello rails"}, "commit"=>"view schedule"} 

i tried use strong params user.find_by(name: params[:users][:name]) throws error "undefined method `[]' nil:nilclass".

i think going wrong somewhere. please correct me. thank time.

issue lies here:

parameters: {"utf8"=>"✓", "/users"=>{"name"=>"hello rails"}, "commit"=>"view schedule"} 

do see /users key in params? shoudn't there. indicates problem form:

<%= form_for users_path, :url => {:action => "testing", :name => :name}, :html => {:method => :get} |f| %> 

first argument expected string (which used name of form params) or activemodel object. in case, string returned users_path, '/users'. should @testing

<%= form_for @testing, :url => {:action => "testing", :name => :name}, :html => {:method => :get} |f| %> 

that fix current issue, shortly after that, should go separate question.
