[英]Grails Plugin Searchable - default wildcard search
有沒有辦法用通配符自動包裝所有搜索?
例如:
Book.search("*${params.q}*", params)
我不熟悉.search(你使用插件嗎?)。 但是,對於模型中的通配符搜索,我通常在域模型類中創建一個方法。 在你的例子中,
在Book模型類中:
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
}
}
在你的控制器中:
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)
}
