html - NoMethodError in Users#show error? -

when log in user rails login screen, tries redirect me user's profile page upon verifying login credentials, however, reason receive error upon landing on profile page (show.html.erb):

nomethoderror in users#show <%= @user.email %> in show.html.erb

i'm not sure why, email field not nil in database? search user in rails console verify this:

 => #<user id: 11, firstname: "leila", lastname: "law", email: "leila@gmail.com", created_at: "2016-01-24 19:49:13", updated_at: "2016-01-24 19:49:13", password_digest: "$2a$10$wdtn0ylur3w/znfahymzzukvziql1prajowytkk3v.6...", password: nil> 

see code below - thank you!

@user not assigned in controller. should change

 user = user.find_by(email: params[:session][:email].downcase) 

to

 @user = user.find_by(email: params[:session][:email].downcase) 

you'll have update occurrences of user in controller. notice space here

params[:session][:email] .downcase 

it should be

params[:session][:email].downcase 

moreover, if session value never set before, controller crash there no downcase nil.
