记录下来lambda的用处
@required_attributes = [:member, :project,:membership_role, :membership_type]
@hash = @required_attributes.inject({}) { |memo, obj| memo[obj] = Factory(obj); memo }
hash.keys.each do |key|
? ? h_c = hash.clone
? ? h_c.delete(key)
? ? lambda{
? ? ? obj.create!(h_c)
? ? }.should raise_exception(
? ? ? ActiveRecord::RecordInvalid,
? ? ?"Validation failed: #{key.to_s.gsub(/_id/, '').capitalize.gsub(/_/, ' ')} can't be blank"
? ? )?
?end?
