测试神殿宝石返回误差未定义方法`set_derivatives‘

Question

我正试着通过神殿来测试上传。我有Minio，并遵循了本教程https://shrinerb.com/docs/testing#test-data

然而，FactoryBot.lint从链接中提供的TestModule代码返回以下错误：

profilepic - undefined method `set_derivatives' for #<Shrine::Attacher:0x000055ee893dfe00 @file=#<Shrine::UploadedFile storage=:store id="8aa14e79342fde0077fd48f1035f56c3" metadata={"size"=>576152, "mime_type"=>"image/jpeg", "filename"=>"profile_pic.jpg"}>, @cache=:cache, @store=:store, @context={}, @previous=nil, @column_serializer=Shrine::Plugins::Column::JsonSerializer, @model_cache=true, @model=nil, @destroy_block=nil, @promote_block=nil, @errors=[]> (NoMethodError)

# ./spec/support/factory_bot.rb:7:in `block (2 levels) in <top (required)>'

你知道怎么回事吗？

Answer 1

从错误的角度看，derivatives插件似乎没有加载。https://shrinerb.com/docs/plugins/derivatives

将此添加到测试模块中

Shrine.plugin :derivatives
