In my user_sessions_controller:
class UserSessionsController < ApplicationController
before_filter :require_no_user, :only => [:create, :new]
before_filter :require_user, :only => :destroy
def new
@user_session = UserSession.new
@message = "Hello."
end
def create
@user_session = UserSession.new(params[:user_session])
if @user_session.save
flash[:notice] = "Login successful!"
redirect_back_or_default admin_path
else
render :action => :new
end
end
def destroy
current_user_session.destroy
flash[:notice] = "Logout successful!"
redirect_back_or_default new_user_session_url
end
end
========
In views/user_sessions/new.html.erb:
<!--user_sessions#new-->
Admin Login
<%= @message %>
========
In spec/views/user_sessions/new.html.erb_spec.rb:
require 'spec_helper'
describe "user_sessions/new.html.erb" do
context "displays the admin login form" do
it "shows the title" do
render
rendered.should have_content("Admin Login") # this is fine
rendered.should have_content("Hello.") # I added this just to test something simple, but it didn't work
end
it "shows the form"
it "shows the button"
end
end
========
If I do "rails server" and check out the page in the browser, there is the "Hello." just as I expect. But the spec test fails to get it.. it /should/ pass:
1) user_sessions/new.html.erb displays the admin login form shows the title
Failure/Error: rendered.should have_content("Hello.")
expected there to be content "Hello." in "Admin Login\n\n\n\n"
# ./spec/views/user_sessions/new.html.erb_spec.rb:9:in `block (3 levels) in <top (required)>'
So why might the <%= %> not be properly showing the @message?
I actually originally had the form code in the view:
<%= form_for @user_session, :url => user_session_path do |f| %>
<%= f.label :login %>
<%= f.text_field :login, :id=>"admin_login" %>
<%= f.label :password %>
<%= f.password_field :password, :id=>"admin_password" %>
<%= f.submit "Login", :id=>"admin_login_button" %>
<% end %>
.. but testing for this yielded
Failure/Error: render
ActionView::Template::Error:
undefined method `model_name' for NilClass:Class
So the @user_session variable wasn't being recognized by the spec test. Similar problem?
Assistance is appreciated.
