保险丝盒中的面包屑4/5

我与Fusebox合作了很长时间,但仍然无法理解这一部分:

电路结构类似于/foo/bar/widgets/

无论如何,曾经我的想法是为每个控制器融合使用名为“parent”(或任何东西)的自定义词汇,在这里您放置上一级融合的名称。

但我记得,这个方法仅在使用XML样式的电路时才适用,在这种电路中,您总是可以从全局容器中获取任何FuseAction信息,所以我没有做到这一点,因为大量使用了非XML样式。

编辑:带词典的示例

这只适用于 传统保险丝盒5 .

假设我们已经创建了以下词汇定义 /lexicon/bc/parent.cfm :

<cfscript>
    if (fb_.verbInfo.executionMode is "start") {
        // validate fb_.verbInfo.attributes contents
        if (not structKeyExists(fb_.verbInfo.attributes,"value")) {
            fb_throw("fusebox.badGrammar.requiredAttributeMissing",
                        "Required attribute is missing",
                        "The attribute 'value' is required, for a 'parent' verb in fuseaction #fb_.verbInfo.circuit#.#fb_.verbInfo.fuseaction#.");
        }
        // compile start tag CFML code
        circuit = fb_.verbInfo.action.getCircuit().getName();
        fa = fb_.verbInfo.action.getCircuit().getFuseactions();
        fa[#fb_.verbInfo.fuseaction#].parent = circuit & "." & fb_.verbInfo.attributes.value;
    } else {
        // compile end tag CFML code
    }
</cfscript>

基本上,这是专门为lexicon复制粘贴的标准lexicon标记 parent .

假设我们使用的是Fusebox 5骨架示例,那么Contler可以如下所示:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE circuit>
<circuit access="public" xmlns:bc="bc/">

    <postfuseaction>
        <do action="layout.mainLayout" />
    </postfuseaction>

    <fuseaction name="welcome" bc:parent="">
        <do action="time.getTime" />
        <do action="display.sayHello" />
    </fuseaction>

    <fuseaction name="widgets" bc:parent="app.welcome">
        <do action="display.showWidgets" />
    </fuseaction>

    <fuseaction name="widget" bc:parent="app.widgets">
        <do action="display.showWidget" />
    </fuseaction>

</circuit>

它显示了词汇如何用于每个融合。请注意,如果不定义属性 bc:parent 稍后它不会出现在自定义属性结构中。

可以只使用FuseAction名称作为父级,如果您在同一个电路中拥有所有链,则以后可以更容易地使用它。

最后,一些快速代码来构建这些东西。请看评论,它们应该足够有用。

<!--- path data container with current fuseaction saved --->
<cfset arrBreadcrumbs = [] />
<cfset ArrayAppend(arrBreadcrumbs, attributes.fuseaction) />

<!--- pull the current circuit fuseactions --->
<cfset fuseactions = myFusebox.getApplication().circuits[ListFirst(attributes.fuseaction,'.')].getFuseactions() />
<!--- OR <cfset fuseactions = application.fusebox.circuits[ListFirst(attributes.fuseaction,'.')].getFuseactions()> --->

<!--- pull the current fuseaction custom attributes --->
<cfset fa = ListLast(attributes.fuseaction,'.') />
<cfset customAttributes = fuseactions[fa].getCustomAttributes('bc') />

<!--- save the parent fuseaction name if present -- KEY CHECK IS RECOMMENDED --->
<cfif StructKeyExists(customAttributes, "parent")>
    <cfset ArrayPrepend(arrBreadcrumbs, customAttributes.parent) />
</cfif>


<!--- let's say we know that parent is there... --->

<!--- pull the found fuseaction custom attributes --->
<cfset fa = ListLast(customAttributes.parent,'.') />
<cfset customAttributes = fuseactions[fa].getCustomAttributes('bc') />

<!--- save the parent fuseaction name if present --->
<cfif StructKeyExists(customAttributes, "parent")>
    <cfset ArrayPrepend(arrBreadcrumbs, customAttributes.parent) />
</cfif>


<!--- render the collected path --->
<cfoutput>
<cfloop index="crumb" from="1" to="#ArrayLen(arrBreadcrumbs)#">

    <!--- to have a nice labels you can use another lexicon --->
    <a href="#myself##arrBreadcrumbs[crumb]#">#arrBreadcrumbs[crumb]#</a> <cfif crumb LT ArrayLen(arrBreadcrumbs)>&gt;</cfif>

</cfloop>
</cfoutput>

所以输出应该如下所示: app.welcome > app.widgets > app.widget

这是我用的东西…
