我使用paperclip-4.2.0 + rspec 3.0.3和rails 4.1.4并为回形针附件大小验证写了rspec并且发生了以下问题
Failure/Error: it { should validate_attachment_size(:image).less_than(8.megabytes) }
NoMethodError:
undefined method `[]' for nil:NilClass
我按照How can I use Rspec to test that a model using Paperclip is validating the size of an uploaded file?的解决方案，但仍然面临这个问题，任何人都可以帮助我......
