Can't link to another page with user

I want link to another page with my user, but i have an error:

RuntimeError in WelcomeController#edit
Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id

In my current page

<%= link_to "edit", welcome_edit_path(@user) %>

thi is my controller

 def edit
   user = User.find_by_id(@user.id)
 end

  get "micropost/new"

  get "user/new"
  get "user/saved"

  get "post/new"

  get "welcome/index"
  get "welcome/sucess"
  get "welcome/edit"
  root :to => "welcome#index"
  get '/users/:id', :to => 'welcome#sucess', :as => "user"

Your code in edit method makes no sense. First thing, you have to define your route properly:

get '/welcome/edit/:id', to: 'welcome#edit', as: 'welcome_edit'

Then, in the WelcomeController:

def edit
  @user = User.find(params[:id])
end

and the link to this page:

<%= link_to 'edit', welcome_edit_path(@user) %>
