my searchable on grails

Posted: December 27, 2008 | Author: | Filed under: code, grails, programming | 1 Comment

Within grails, Book class-domain is very common used as sample. And here is my simple implementation of searchable plugin on Book class-domain:

Book.groovy

class Book {

String bookName
Date release
String description

static Searchable = true

}

BookController.groovy

def search = {

   def bookInstanceList
    def searchResult
    if (params.query) {
        searchResult = Book.search('*'+params.query+'*')
        bookInstanceList = searchResult.results
    }
    else
        bookInstanceList = Book.list()
    render(view:'list', model:[bookInstanceList:bookInstanceList, searchResult:searchResult, query:params.query])
}

List view

<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
        <meta name="layout" content="main" />
        <title>Book List</title>
    </head>
    <body>
        <div class="nav">
            <span class="menuButton"><a class="home" href="${createLinkTo(dir:'')}">Home</a></span>
            <span class="menuButton"><g:link class="create" action="create">New Book</g:link></span>
        </div>
        <div class="body">
            <h1>Book List</h1>
            <g:if test="${flash.message}">
                <div class="message">${flash.message}</div>
            </g:if>
            <div class="list">
                <div class="nav">
                    <g:form name="search" action="search">
                        search: <input type="text" name="query" value="${query}"/>
                        <input type="submit" value="search">
                    </g:form>
                </div>
                <table>
                    <thead>
                        <tr>
                            <g:sortableColumn property="id" title="Id" />
                            <g:sortableColumn property="bookName" title="Book Name" />
                            <g:sortableColumn property="description" title="Description" />
                            <g:sortableColumn property="release" title="Release" />
                        </tr>
                    </thead>
                    <tbody>
                        <g:each in="${bookInstanceList}" status="i" var="bookInstance">
                            <tr class="${(i % 2) == 0 ? 'odd' : 'even'}">
                                <td><g:link action="show" id="${bookInstance.id}">${fieldValue(bean:bookInstance, field:'id')}</g:link></td>
                                <td>${fieldValue(bean:bookInstance, field:'bookName')}</td>
                                <td>${fieldValue(bean:bookInstance, field:'description')}</td>
                                <td>${fieldValue(bean:bookInstance, field:'release')}</td>
                            </tr>
                        </g:each>
                    </tbody>
                </table>
            </div>
            <div class="paginateButtons">
                <g:if test="${searchResult}">
                    <g:paginate total="${searchResult.total}" params="[    query:query]"/>
                </g:if>
                <g:else>
                    <g:paginate total="${Book.count()}" />
                </g:else>
            </div>
        </div>
    </body>
</html>

and here is the shoot:

searchable plugin on book domain-class

The search criteria above is based on word match, for more details about more search criteria or all features on grails searchable please see the documentation on grails plugins site
