Redirection

Often, we need to redirect to a new url in the middle of a request. A successful createaction, for instance, will usually redirect to the show action for the model we just created. Alternately, it could redirect to the index action to show all the things of that same type. There are plenty of other cases where redirection is useful as well.

Calling redirect_to will halt the request lifecycle.

Redirect to URL

redirect_to(location: "", status: 302, params: { "key" => "value" }, flash: { "user_id" => "1" })

Redirect to Action

redirect_to(action: :index, status: 302, params: { "key" => "value" }, flash: { "user_id" => "1" })

Redirect to Controller Action

redirect_to(
  controller: :symbol, 
  action: :index, 
  status: 302, 
  params: { "key" => "value" }, 
  flash: { "user_id" => "1" })

Redirect Back

redirect_back(status: 302, params: { "key" => "value" }, flash: { "user_id" => "1" })
