Rails 3 / RSpec：控制器测试-在我的测试中访问类函数将返回SQLite3 :: SQLException“无此表”错误

Question

I have a Page scaffold that I created through rails generate scaffold. I ran rake db:migrate, and viewing the database through SQLite Database Browser reveals that it in fact exists. I can go to the rails console and run:

    Page.all.each {|page| puts page.url}

When I run this, it in fact returns the right results (eg, the value of url for each record of Page.

What I am trying to do is set up an rspec test in my pages controller test to see that each of the routes I've set up in config/routes.rb actually works. So I have a test defined in spec/controllers/pages_controller_spec.rb as follows:

describe PagesController do

    Page.all.each do |page|
        describe "GET /#{page.url}" do
            it "should be able to get at page at #{page.url}" do
                get "/#{page.url}"
                response.should be_successful
            end
        end
    end

end

This test does not run. Instead, it generates the following message:

C:/Ruby192/lib/ruby/gems/1.9.1/gems/activerecord-3.0.1/lib/active_record/connection_adapters/abstract_adapter.rb:202:in `rescue in log': SQLite3::SQLException: no such table: pages: SELECT     "pages".* FROM       "pages" (ActiveRecord::StatementInvalid)

Does anyone know what is going on? Or, in the alternative, does anyone know why this will work in my Rails Console, but not in my rspec tests?

Thank you so much. I am relatively new to Rails, so still learning a lot!

运行rake db:test:prepare以确保在测试环境中设置了数据库模式。
