Issue using VCR to use Webmock to Mock URLs in Ruby App

[steve87....@gmail.com]

I want to be able to record specific requests and have ALL the requests/responses be logged to the SAME file if the URL host is dev1-pb1.  See my code below.  This code definitely ignores all requests that do NOT have dev1-pb1 as the URI.host.  When I make the first RESTful call  http://dev1-pb1:8080/pb-client-wrapper/model/123446, it creates the pb_mock_data file with this request and response in it which I expect.   When I make a subsequent request where the model id changes such as http://dev1-pb1:8080/pb-client-wrapper/model/634005, it throws the error below.  I can get it to work creating unique mock files.  Please advise!  Thanks!  

NOTE:  Ideally, I would like to have a regex in the mock yaml file where ALL requests matching a pattern the URL.   I tried putting a path_regex entry in the mock yaml file, but that didn't resolve the issue.    Can this be done?

In an initializer that loads when my ruby app starts, I have the following code:

if FullSite::Application.config.mock_pb_requests == true

  VCR.configure do |c|

    c.ignore_request do |request|

      URI(request.uri).host != 'dev1-pb1'

    end

    c.allow_http_connections_when_no_cassette = true

    c.cassette_library_dir = 'test/mocked_data/pb-client-wrapper'

    c.hook_into :webmock

    c.around_http_request do |request|

      VCR.use_cassette("pb_mock_data", &request)

    end

  end

end

Error on second request where the model id changes:

An HTTP request has been made that VCR does not know how to handle:

  GET http://dev1-pb1:8080/pb-client-wrapper/model/634005

There is currently no cassette in use. There are a few ways

you can configure VCR to handle this request:

  * If you're surprised VCR is raising this error

    and want insight about how VCR attempted to handle the request,

    you can use the debug_logger configuration option to log more details [1].

  * If you want VCR to record this request and play it back during future test

    runs, you should wrap your test (or this portion of your test) in a

    `VCR.use_cassette` block [2].

  * If you only want VCR to handle requests made while a cassette is in use,

    configure `allow_http_connections_when_no_cassette = true`. VCR will

    ignore this request since it is made when there is no cassette [3].

  * If you want VCR to ignore this request (and others like it), you can

    set an `ignore_request` callback [4].

The default record mode is :once, which allows a cassette to be recorded once, and then will only allow it to be played back in the future:

It sounds like you want to use the :new_episodes record mode:

You can control which requests match using custom request matchers:
