ruby on rails - Could Not Find Table 'Name' -


i'm new ruby , can't solve problem. tried troubleshooting solutions in similar posts , none fixed problem. hoping might have idea on what's wrong. when attempt login, i'm told cannot find table name'. i'm able create user in rails console , able locate via user.find_by(name: ""). shows in database.

def create   user = user.find_by(name: params[:session])   if user && user.authenticate(params[:session][:password])   else      flash.now[:danger] = 'invalid username/password combination'      render 'new'   end end

migration:

class createusers < activerecord::migration   def change     create_table :users |t|       t.string :name       t.timestamps null: false     end   end end

you have not provided key :name:

user = user.find_by(name: params[:session][:name])
