ninitialized constant Pickle::Adapter::DataMapper

[Aleksander Dąbrowski]

Hi,

I'm writing a little application in Sinatra and Datamapper, and I'm
using Cucumber and Capybara. I wanted to use pickle, so I added file
at support/pickle.rb with following content:

require 'pickle/world'

Pickle.configure do |config|
config.adapters = [ DataMapper::Resource]
end

Unfortunately i got this error:

I also tried to do:

config.adapters = [ :data_mapper ]

But the result was the same.

My application is here: http://github.com/tjeden/sinatra-pong/tree/pickle

What I am doing wrong?

Hi there,

In 0.4, the adapters setting is for your factory adapters (ie. machinist or similar), and you need to provide a class that is an adapter (not an ORM class)

But pickle should work for you without any config, did you try it without adding the adapter config line?

If you are getting errors without any extra config, then try this before Pickle.config:

require 'pickle/adapters/data_mapper'

Let me know how you get.

Cheers,
Ian

Hi,

It helped, thanks.
require 'pickle/world'
did the job.

But now I have another problem. When I run me scenario allone i.e.:
cucumber features/report_match.feature
It works well.

But when I run all scenarios with
cucubmer features I got:
Given a dm_user "Jack" exists with email: "ja...@example.com" #
features/step_definitions/pickle_steps.rb:4
stack level too deep (SystemStackError)
./features/step_definitions/pickle_steps.rb:5:in `/^((?:(?:)|(?:
(?:a|an|another|the|that) )?(?:(?:(?:(?:first|last|(?:\d+(?:st|nd|rd|
th))) )?(?:dm[_ ]user))|(?:(?:dm[_ ]user)(?::? "(?:[^\"]|\.)*")))))
exists?(?: with ((?:(?:\w+: (?:(?:(?:)|(?:(?:a|an|another|the|that) )?
(?:(?:(?:(?:first|last|(?:\d+(?:st|nd|rd|th))) )?(?:dm[_ ]user))|(?:
(?:dm[_ ]user)(?::? "(?:[^\"]|\.)*"))))|(?:"(?:[^\"]|\.)*"|nil|true|
false|[+-]?[0-9_]+(?:\.\d+)?))), )*(?:\w+: (?:(?:(?:)|(?:(?:a|an|
another|the|that) )?(?:(?:(?:(?:first|last|(?:\d+(?:st|nd|rd|th))) )?
(?:dm[_ ]user))|(?:(?:dm[_ ]user)(?::? "(?:[^\"]|\.)*"))))|(?:"(?:[^
\"]|\.)*"|nil|true|false|[+-]?[0-9_]+(?:\.\d+)?)))))?$/'
features/report_match.feature:8:in `Given a dm_user "Jack"
exists with email: "ja...@example.com"'

I'm using http://github.com/maxjustus/sinatra-authentication, with
datamapper, maybe it causes the problem?

Hi,

Not sure what's going on there, if it's working with one scenario, I'd expect it to work with many.

Could you push your code to a branch, or a gist, for me to take a gander?

Cheers,
Ian

Hi,

This is my branch of my application with pickle
