Rails回形針搜索文件名

Question

我要求用戶能夠搜索通過回形針上傳的文件名。 查看上傳的文檔看起來像這樣...

2.0.0-p353 :002 > d=Document.last
  Document Load (0.4ms)  SELECT  "documents".* FROM "documents"   ORDER BY "documents"."id" DESC LIMIT 1
 => #<Document id: 5, name: "hampton_george_27_70", transcription: "Asheville Nov 8th 1853 received of James A. Patton...", created_at: "2014-08-22 16:10:19", updated_at: "2014-08-22 16:37:51", document_file_name: "hampton_george_27_70.jpeg", document_content_type: "image/jpeg", document_file_size: 519652, document_updated_at: "2014-08-22 16:10:19"> 
2.0.0-p353 :003 > d.document_file_name
 => "hampton_george_27_70.jpeg" 

但是這些不是傳統的rails型模型，那么我將如何搜索它們呢？

Answer 1

Document似乎是一個模型，因此您可以對其進行查詢。 例如，要搜索文件名中帶有“ george”的文檔：

search_term = "george"
documents = Document.where(['document_file_name LIKE ?', "%#{search_term}%"])
