在 existDB 中使用模板的异常

Question

我正在尝试使用 existDB 将参数传递给应用程序，我的问题是在使用模板时，它给了我这个错误：

templates:NotFound No template function found for call  app:getBusPorMatricula [at line 189, column 85, source: C:\Users\rober\Documents\eXist\webapp\WEB-INF\data\expathrepo\shared-0.4.0\content\templates.xql]

我实际拥有的代码是这个，我拥有在您创建应用程序时自动生成的所有代码，除了这个文件：

app.xql:

xquery version "3.0";

module namespace app="http://gijonapp1.es/templates";


declare namespace bus="http://docs.gijon.es/sw/busgijon.asmx";

import module namespace templates="http://exist-db.org/xquery/templates" ;
import module namespace config="http://gijonapp1.es/config" at "config.xqm";

 : This is a sample templating function. It will be called by the templating module if
 : it encounters an HTML element with an attribute data-template="app:test" 
 : or class="app:test" (deprecated). The function has to take at least 2 default
 : parameters. Additional parameters will be mapped to matching request or session parameters.
 : 
 : @param $node the HTML node with the attribute which triggered this call
 : @param $model a map containing arbitrary data - used to pass information between template calls
 :)
declare function local:getNumeroBusesFuncionando()
{
    let $numero:=count(doc('http://datos.gijon.es/doc/transporte/busgijontr.xml')//bus:posicion)
    return $numero
};

declare function local:getBusesFuncionando()
{
    <buses numero="{local:getNumeroBusesFuncionando()}">{
    for $bus in doc('http://datos.gijon.es/doc/transporte/busgijontr.xml')//bus:posicion
    order by xs:integer($bus/bus:idlinea)
    return <bus>{$bus/bus:matricula,$bus/bus:idlinea,$bus/bus:idtrayecto,$bus/bus:utmx,$bus/bus:utmy}</bus>}
    </buses> 
};

declare function app:showMenu($node as node(), $model as map(*)){
    <div>
        <ul>
            <li><a href="./busesFuncionando.html">Buses Funcionando</a></li>
            <form action="./busPorMatricula.html">
            Inserte la matricula del autobus a buscar :
                <input type="text" name="matricula"/>
                <input type="submit" value="Buscar"/>
            </form>
        </ul>
    </div>
};

declare function app:showBusFuncionando($node as node(), $model as map(*)) {

    <div>
         <h2> Buses funcionado a las {hours-from-time(current-time())}:{minutes-from-time(current-time())}</h2>

        <ul>

                {
                    for $bus in local:getBusesFuncionando()//bus
                    return <li><b>Linea :{$bus/bus:idlinea}</b> Trayecto : {$bus/bus:idtrayecto} Matricula : {$bus/bus:matricula} Posicion : {$bus/bus:utmx},{$bus/bus:utmy}</li>
                }
        </ul>
    </div>

};

(: !!!!!The PROBLEM is HERE !!!!:)

declare function app:getBusPorMatricula($node as node(), $model as map(*))
{
    let $matricula:=request:get-parameter('matricula', '')

    let $bus :=doc('http://datos.gijon.es/doc/transporte/busgijontr.xml')//bus:posicion[bus:matricula=$matricula]
   return
    <p>asd</p>

};

这是使用模板的页面：

index.html:

 <div xmlns="http://www.w3.org/1999/xhtml" data-template="templates:surround" data-template-with="templates/page.html" data-template-at="content">
        <h1> Menu </h1>
        <div data-template="app:showMenu"/>
    </div>

busPorMatricula.html:

<div xmlns="http://www.w3.org/1999/xhtml" data-template="templates:surround" data-template-with="templates/page.html" data-template-at="content">
    <h1> Bus con matricula </h1>
    <div data-template=" app:getBusPorMatricula" data-template-matricula="{request:get-parameter('matricula', ''}"/>
</div>

我想用这一切做的是给一个注册号，显示带有该号码的公交车的一些信息

感谢您的帮助

Answer 1

我发现了错误，它在 "busPorMatricula.html"

中的 html 的代码中

data-template 的内容中有一个 space，这就是问题所在。

我希望它对其他人有帮助，我花了大约 4 个小时寻找比这更复杂的东西。
