Rails undefined method errors showing on session controller

Question

I am building an application in which I am trying to login using clearance.I have build login and sign up page .They are working very smooth but the problem is when I am trying to show error when user enters any wrong email or password so my <% if :session.errors.any? %> is not working .It is saying undefined method `errors' for :session:Symbol
[Session_controller]

class SessionController < ApplicationController

    def new
    end

    def create
        @session = authenticate(params)
        sign_in(@session) do |status|
            if status.success?      
                redirect_to root_path
            else
                render 'new'    
            end
        end
    end

    private
          def user_params
            params.require(:session).permit(:email,:password)
          end
end

[session/_form.html.erb]

Answer 1

You are calling errors on :session, which is a symbol. You may want to try calling errors on @session.

Answer 2

undefined method `errors' for :session:Symbol

errors should be called on a new model instance i.e, Model.new. You should have @session defined as Session.new in new method, the below should work

#session_controller
def new
  @session = Session.new
end

#in the view
<% if @session.errors.any? %>
