Many models, one set of cucumber steps: BOOYAH!! also: machinist ftw

model_steps.rb

# make sure there are none
Given /^no (.+) exists$/ do |model_name|
  model_class(model_name).destroy_all
end

# single model, one attribute of interest
Given /^a (?:(.+) )?(.+) with (.+) "(.+)" exists$/ do |blueprint_name, model_name, key, value|
  model_class(model_name).make blueprint_name, key => value
end

# single model, attributes as rows
Given /^the following (?:(.+) )?(.+) exists:$/ do |blueprint_name, model_name, data|
  model_class(model_name).make blueprint_name, data.rows_hash
end

# several models, attributes as columns
Given /^the following (?:(.+) )?(.+) exist:$/ do |blueprint_name, model_name, data|
  model = model_class(model_name)
  
  data.hashes.each do |datum|
    model.make blueprint_name, datum
  end
end

# given number of models, attribute values irrelevant
Given /^(\d+) (?:(.+) )?(.+) exist$/ do |count, blueprint_name, model_name|
  model = model_class(model_name)
  
  count.to_i.times { model.make blueprint_name }
end



# DRY
def model_class(model_name)
  model_name.titleize.gsub(/\s/, '').singularize.constantize
end
