The first place to go is the official [Relish docs][1], they have gotten a significant improvement over the years and are now my first place to look.

At the time of writing this answer originally, this [gist][2] was solid. It contains matchers for the following:

 - [Capybara][3]
 - [Paperclip with Shoulda][4]
 - [Rspec Rails][5]
 - [Rspec Exceptions][6]
 - [Shoulda Matchers][7]

Not sure why you feel rdoc.info isn&#39;t useful - here&#39;s the matcher docs there:

http://rubydoc.info/gems/rspec-expectations/2.0.1/RSpec/Matchers

It may be that you&#39;re looking in the wrong spot; these were in the RSpec::Expectations gem, which is split out from the core in Rspec 2.

Having a terrible time finding **RSpec-2** (and **rspec-rails**) documentation. Specifically I want to look up all available Matchers... but how? 

I&#39;ve tried:

 - [RSpec.info][1] : outdated - RSpec 1.x
 - [rdoc.info][2] : seems useless, to me anyway. (incomplete?)
 - [RSpec-Relish][3] : confusing. incomplete? how would one look up available Matchers?
 - [GitHub Wiki][4] : scattered info. unorganized. incomplete?

Yes, I&#39;m aware of [The Book][5]...but, seriously, isn&#39;t this stuff online? 

Even tried `rake doc:plugins` but it didn&#39;t work. Too green to know why...

apparently there used to be some decent 1.x docs on [rspec.rubyforge.org][6]. but they&#39;re appear to be long gone...

Where are these docs hiding?

I am trying to render results from more than one model in JSON.  The following code in my controller only renders the first result set:

      def calculate_quote
        @moulding = Moulding.find(params[:id])
        @material_costs = MaterialCost.all

        respond_to do |format|
          format.json  { render :json =&gt; @moulding }
          format.json  { render :json =&gt; @material_costs }
        end
      end

Any help would be much appreciated, thanks.

I&#39;m using Rails 2.3.x.  I would like a small section of code to run if and only if the `config.cache_classes` is true.  By default, that&#39;s true for production and false for development.

How do I access the value of config.cache_classes from outside of my environment.rb, development.rb, and production.rb files?  It&#39;s easy to tell if we are in production or development, `Rails.env` will give us the answer.  But there&#39;s no guarantee the developer hasn&#39;t set `config.cache_classes = true` in development.

I certainly understand that you do not generally want to run separate code paths in development and production.  In this particular instance, we are simply not performing some work on startup; if we need to perform it later, we will do so, both in development and production.

I&#39;m having a problem matching user password using devise gem in rails. User password stored on my db which is encrypted_password and i am trying to find user by password, but I don&#39;t understand how to match password from form and encrypted_password in my db.

I&#39;m new to Rails so my current project is in a weird state. 

One of the first things I generated was a &quot;Movie&quot; model. I then started defining it in more detail, added a few methods, etc.

I now realize I should have generated it with `rails generate scaffold` to hook up things like the routing, views, controller, etc. 

I tried to generate the scaffolding but I got an error saying a migration file with the same name already exists.

What&#39;s the best way for me to create scaffolding for my &quot;Movie&quot; now? (using rails 3)

By default,

     rails s #running on 3000 port

Now I want to run it on port 80. So I tried:

     sudo rails -s -p80

But it threw an error:

    mlzboy@mlzboy-MacBook ~/my/b2c2 $ sudo rails s -p80
    sudo: rails: command not found

I used rvm to install ruby &amp; rails. It seems rvm is user specified. Is it not able to find rails in root?

I also tried below code:

    mlzboy@mlzboy-MacBook ~/my/b2c2 $ which rails
    /home/mlzboy/.rvm/gems/ruby-1.9.2-p0/bin/rails
    mlzboy@mlzboy-MacBook ~/my/b2c2 $ sudo /home/mlzboy/.rvm/gems/ruby-1.9.2-p0/bin/rails s -p80

It is pretty easy with the added generator of rspec-rails to set up RSpec for testing a Rails application. But how about adding RSpec for testing a gem in development?
I am not using jeweler or such tools. I just used Bundler (`bundle gem my_gem`) to setup the structure for the new gem and edit the *.gemspec manually.
I also added `s.add_development_dependency &quot;rspec&quot;, &quot;&gt;= 2.0.0&quot;` to gemspec and did a `bundle install`.

Is there some nice tutorial what to do next to get RSpec working?

Capybara: How do I fill in a input field by its ID

When developing gems in Ruby, I almost always need a file in which I can configure RSpec to my needs and maybe before doing that, require some helper modules which should be available in all my `spec` examples.

In Rails applications a file named `spec/spec_helper.rb` is used for that. One thing that annoys me is that in the typical Rails environment, you have to require this spec_helper.rb file in every file that contains examples for it to be loaded. In the past I had a lot of problems with this related to changing load paths and relative require paths inside the example files.

Now for my gems, I would wish to have a way to just say RSpec to require the spec_helper.rb file before loading any of the examples files. Independent of the fact if I call rspec executable, or the rake spec task which I may define in my Rakefile.

I know I can tell RSpec only the location of my spec_helper.rb is this spec_helper.rb requires all the example files manually, but I would also like to avoid the additional maintenance of that approach.

Is there a nicer way to accomplish this?

How to load a spec_helper.rb automatically in RSpec 2

I think there&#39;s a way to run only tests with a given label. Anybody know?

How do I run only specific tests in Rspec?

After significant troubleshooting, I figured out that I needed to run `rake spec` once (I can abort with control-c) before I can run rspec directly (e.g. on a subset of our specs). We are running Rails 3.0.7 and RSpec 2.5.0.

Clearly, rake is running some important database setup tasks / code (we have custom code in the root level rails Rakefile and possibly other places).

**How can I run the rake test database setup tasks / code without running `rake spec`?**

In addition to being able to run rspec on a subset of files, I am using [specjour][1] to spread our specs across multiple cores (haven&#39;t had success with spreading them across the LAN yet), but I see the same behavior as for running rspec directly: I need to run `rake spec` on each test database (assuming two cores) before specjour works:

    rake spec TEST_ENV_NUMBER=1
    control-c (after tests start)
    rake spec TEST_ENV_NUMBER=2
    control-c (after tests start)
    specjour

Note: my config/database.yml has this entry for test (as is common for the parallel testing gems):

    test:
      adapter: postgresql
      encoding: unicode
      database: test&lt;%=ENV[&#39;TEST_ENV_NUMBER&#39;]%&gt;
      username: user
      password:

[parallel_tests][2] seems to set up its databases correctly, but many of our specs fail.

I should also mention that running `specjour prepare` causes Postgres to log errors that it can&#39;t find the databases, but it creates them (without tables). On a subsequent run, no errors are logged, but also no tables are created. It is possible that my whole issue is simply a bug in `prepare`, so I reported it on github.

I think that I can run arbitrary code on each specjour test database by setting `Specjour::Configuration.prepare` in .specjour/hooks.rb, so if there&#39;s any rake tasks or other code that I need to run, it may work there.

How do you test `redirect_to :back` in rspec?

I get 

&gt;`ActionController::RedirectBackError`:&lt;br&gt;
&gt;No `HTTP_REFERER` was set in the request to this action, so `redirect_to :back` could not be called successfully. If this is a test, make sure to specify `request.env[&quot;HTTP_REFERER&quot;]`.

How do I go about setting the `HTTP_REFERER` in my test?
 


Rspec testing redirect_to :back

I have `test-unit` installed and `rspec` installed (along with `-core`, `-expectations`, `-mocks` and `-rails` version 2.6.x). When I run the command `rails new foo`, it uses `test-unit` to generate the test stub files instead of `rspec`.

Is there an option where I can tell rails to use rspec to generate the tests instead?
