The error is Sinatra does not know this path. I want to create the path from question/show.erb view to answer/new.erb via submit answer button. What should I do?

question_controller (Controller folder)

get '/questions/:id/show' do

question/show (View folder)

<form method="get" controller="answers" action="/answers/question/<%[email protected]%>/new">

erb :'answer/new'
