Grails插件可搜索 - 默認通配符搜索

Question

有沒有辦法用通配符自動包裝所有搜索？

例如爲：

Book.search("*${params.q}*", params) 

Answer 1

我不熟悉.search（您正在使用的插件嗎？）。但是，對於模型中的通配符搜索，我通常會在域模型類中創建一個方法。在你的榜樣，

在Book模型類：

class Book { 
    String title 
    String author 
    int year 

    static List wildSearch(par, val) { 
     def foundList = this.executeQuery("select b FROM Book b WHERE ${par} like \'%${val}%\'") 
     return foundList 
    } 
} 

在你的控制器：

def searchBook = { 
    def b1 = new Book(title: "Farewell To Arms", author: "Ernest Hemingway").save() 
    def b2 = new Book(title: "The Brother's Karamazov", author: "Anton Chekov").save() 
    def b3 = new Book(title: "Brothers in Arms", author: "Cherry Dalton").save() 

    // If you search for "Arms", This returns b1 and b3 
    def found = Book.wildSearch("title", params.title) 
}
