我有一個用於模型的Paperclip的用戶模型,我需要能夠使用RABL爲每個尺寸(小,中,大)返回image_url
。使用RABL從Paperclip返回圖片URL
在mongoid模型,我只想做self.avatar(:original)
但現在沒有什麼工作,我只是得到的附件的空響應
"user" : {
"id" : "50b204e10eae9c55fa000028",
"paperclip::attachment" : {},
"name" : "My Name"
}
/models/user.rb
has_mongoid_attached_file :avatar,
:styles => {
:original => ['1000x1000>', :jpg],
:small => ['64x64#', :jpg],
:medium => ['250x250', :jpg],
:large => ['500x500>', :jpg]
}
/views/posts/base.json.rabl
child :user do
attributes :id, :name
child :avatar do
attributes :original
end
end
