Rails sorcery 新規登録ができない

 解決：view file 

form_for を<table> タグ内部でなく　外部にして、tableタグを囲む。 

コントローラー：

class RegistrationsController < ApplicationController
def new
@user = User.new
end

def create
@user = User.new(params_user)
if @user.save
raise
login(:email, :password)
redirect_to questions_path
else
render :new
end
end

private
def params_user
params.require(:user).permit(:screen_name, :email, :password, :password_confirmation, :status, :child_age1, :child_age2, :residence_country, :residencenow, :school, :origin, :wannaknow, :know, :bio, :mailmagazine, :comment, :privacy)
end
end
