我是 Grails 的新手，从过去几天开始学习 Grails。我正在尝试通过在我的演示 grails 应用程序中使用可搜索插件来添加搜索功能。我成功地在用户搜索中添加了可搜索插件，用户可以在其中搜索其他用户并关注他们。我正在这样做..

grails install-plugin searchable

域 Person.groovy --

package org.grails.twitter

  class Person {

transient springSecurityService

String realName
String username
String password
boolean enabled
boolean accountExpired
boolean accountLocked
boolean passwordExpired
static hasMany = [followed:Person, status:Status]
static searchable = [only: 'realName']

static constraints = {
    username blank: false, unique: true
    password blank: false
}

static mapping = {
    password column: '`password`'
}

Set<Authority> getAuthorities() {
    PersonAuthority.findAllByPerson(this).collect { it.authority } as Set
}

def beforeInsert() {
    encodePassword()
}

def beforeUpdate() {
    if (isDirty('password')) {
        encodePassword()
    }
}

protected void encodePassword() {
    password = springSecurityService.encodePassword(password)
}
   }

查看/可搜索/index.gsp ---

<html>
 <head>
  <meta name="layout" content="main" />
  <title>What Are You Doing?</title>
  <g:javascript library="jquery" plugin="jquery" />
  </head>
  <body>
<h1>Search For People To Follow</h1>
<div class="searchForm">
    <g:form controller="searchable">
        <g:textField name="q" value=""/>
    </g:form>
</div>

    <h1>What Are You Doing?</h1>
    <div class="updateStatusForm">
    <g:formRemote onSuccess="document.getElementById('messageArea').value='';" url="[action: 'updateStatus']" update="messageLists" name="updateStatusForm">
        <g:textArea name="message" value="" id="messageArea" /><br/>
        <g:submitButton name="Update Status" />
    </g:formRemote>
     </div>
    <div id="messageLists">
    <g:render template="messages" collection="${messages}" var="message"/>
</div>
   </body>
   </html>

它工作正常。现在我的问题开始了。现在我想在我的帖子域中添加这个可搜索的内容，用户也可以在其中搜索帖子项目。我正在这样做......

域 Post.groovy --

package groovypublish

class Post {

static hasMany = [comments:Comment]

String title
String teaser
String content
Date lastUpdated
Boolean published = false
SortedSet comments

static searchable = [only: 'title']

static constraints = {
    title(nullable:false, blank:false, length:1..50)
    teaser(length:0..100)
    content(nullable:false, blank:false)
    lastUpdated(nullable:true)
    published(nullable:false)
}
}

这是表单视图

查看/发布/list.gsp --

  ------ some code -----
 <g:form controller="searchable" class="navbar-search pull-left">
   <g:textField name="q" value="" class="search-query" placeholder="Search Posts"/>
 </g:form>

 ------ some code ------

现在，当我尝试按帖子标题搜索帖子时，它会显示错误。它覆盖可搜索的操作。如何解决这个问题呢 ？

您可以使用 searchable 实现自己的搜索方法，从搜索表单中调用控制器函数并执行搜索：

假设您有两种搜索形式：

<g:form controller="postsController" action="postAction" class="navbar-search pull-left">
   <g:textField name="q" value="" class="search-query" placeholder="Search Posts"/>
 </g:form>

和

 <g:form controller="searchable">
        <g:textField name="q" value=""/>
    </g:form>

然后在 PostCONtroller 中，您可以使用 postAction 方法来执行搜索：

def postAction (Integer max) {
        params.max = Math.min(params.max ? params.int('max') : 10, 100)
        params.sort = "id"
        params.order = "desc"

        if(params?.q){


            def result = Post .search(params.q , order:"desc" )

            return [searchResults: result.results, searchResultsCount: result.total, popup : params.popup?.toBoolean()]
        }else{
            [searchResults: Post .list(params), searchResultsCount: Post .count(), popup : params.popup?.toBoolean()]
        }

同样，您可以为另一个搜索使用不同的功能，如果您使用远程表单，那么您需要在搜索页面上有两个不同的 div，并且您可以在那里呈现结果页面。

假设你有：

<g:formRemote name="postSearchForm" update="postSearchResultsDiv" url="[controller: 'post', action:'postAction' , params: [popup: false]]">
                        <label for="searchText">Search Post:</label>
                        <input name="q" type="text" id="searchText" class="input-medium search-query"/>
                        <input id="searchButton" type="submit" class="btn-info" value="Search"/>
                    </g:formRemote>

<div id="postSearchResultsDiv">--Your search result for the form will display here--</div>

这个远程表单将在您的控制器中调用postAction方法，您可以在控制器的视图文件夹中拥有postAction.gsp页面并在那里打印结果。

在您的搜索页面上，postSearchResultsDiv将有搜索结果（postAction GSP 页面输出）

我解决了自己的问题...我已经这样做了..

后控制器 ---

import org.compass.core.engine.SearchEngineQueryParseException
class PostController 
{
   def searchableService

   def searchpost = {
    if (!params.q?.trim()) {
        return [:]
    }
    try {
        return [searchResult: searchableService.search(params.q, params)]
    } catch (SearchEngineQueryParseException ex) {
        return [parseException: true]
    }
    render(view:'searchpost')
   }

  .......
}

搜索表格---

<g:form controller="post" action="searchpost" class="navbar-search pull-left">
   <g:textField name="q" value="" class="search-query" placeholder="Search Posts"/>
 </g:form>

searchpost.gsp //用于显示结果

<html>
   <head>
    <r:require modules="bootstrap"/>
    <meta name="layout" content="main"/>        
   </head>
   <body>
     <g:render template="/layouts/header" />    
     <div class="well"> 
        <g:each var="post" in="${searchResult?.results}">
          <div>
           <h2>${post.title}</h2>
           <p>${post.teaser}</p>
           <p>Last Updated: ${post.lastUpdated}</p>
           <g:link controller="post" action="view" id="${post.id}" class="btn btn-success">
         View this post
          </g:link>
          <g:if test="${post.author == currentLoggedInUser }">
         <g:link controller="post" action="edit" id="${post.id}" class="btn btn-danger">
             Edit this post
         </g:link>
         <g:actionSubmit action="delete" value="${message(code: 'default.button.delete.label', default: 'Delete')}" onclick="return confirm('${message(code: 'default.button.delete.confirm.message', default: 'Are you sure?')}');" class="btn btn-inverse" />
        </g:if>
        <g:form>
     <g:hiddenField name="id" value="${post?.id}" />            
        </g:form>
   </div>

   </g:each>
  </div>        
 </body>
 </html>

它有效:)
