不能用 ColdFusion 中的结构做数学运算

Question

我正在遍历一个列表，如果结构键不存在，我想创建一个结构的结构，但如果它存在，我只想通过添加一个新值来更新其中一个键该键的现有值。它不会那样做，我不知道为什么。

代码如下：

<cfloop list="#recipeItemList#" index="ril">
    <cfset thisrecipe = entityLoadByPK("recipes", #ril#)>

    <cfloop array="#thisrecipe.getrecipeitem()#" index="recipeItems">

        <cfif recipeItems.hasrawMaterial_id()>
            <cfset theitem = entityLoadByPK("rawMaterials", recipeItems.getrawMaterial_id().getid())>

            <cfinvoke method="getPrepByDate" component="/FEcomponents.production" returnvariable="makeAmount">
                <cfinvokeargument name="recipe_id" value="#ril#">
                <cfinvokeargument name="delivery_date" value="#delivery_date#">
            </cfinvoke>

            <cfset thisRecipeYield = #thisRecipe.getYield()#>

            <cfif thisRecipeYield neq 0>
                <cfset recipeRatio = makeAmount / thisRecipeYield>
            </cfif>

            <cfset thisQuantity = recipeRatio * #recipeItems.getitemQuantity()#>

            <cfif structKeyExists(outerstruct, '#theitem.getid()#')>

                <!--- we must add this quantity to the existing key, not create a new one --->
                <cfset addthis = #outerstruct[theitem.getid()].totalToGet# + #thisQuantity#>

                <cfset structInsert(outerstruct[theitem.getid()],'totalToGet', #addthis#,true)>

                <!--- this is just to for testing to see if the value has changed, and it does not the 'addthis' value is always the latest value in the loop--->
                #outerstruct[theitem.getid()].totalToGet# + #thisquantity# = #addthis# <BR>
            <cfelse>
                <!--- create a new struct --->
                <cfset outerstruct[theitem.getid()] = structnew()>
                <cfset outerstruct[theitem.getid()].rawMaterialid = #theitem.getid()#>
                <cfset outerstruct[theitem.getid()].rawMaterialName = #theItem.getName()#>
                <cfset outerstruct[theitem.getid()].totalToGet = #thisQuantity#>
                <cfset outerstruct[theitem.getid()].uom = #theItem.getUOM().getname()#>
            </cfif>
        </cfif>
    </cfloop>
</cfloop>

我哪里做错了。

感谢您的帮助

我认为这会满足您的要求，我删除了一些额外的井号并更改了您更新结构键的方式。抱歉，我无法运行代码，但我相信这应该可行。

<cfloop list="#recipeItemList#" index="ril">
<cfset thisrecipe = entityLoadByPK("recipes", #ril#)>

<cfloop array="#thisrecipe.getrecipeitem()#" index="recipeItems">

    <cfif recipeItems.hasrawMaterial_id()>
        <cfset theitem = entityLoadByPK("rawMaterials", recipeItems.getrawMaterial_id().getid())>

        <cfinvoke method="getPrepByDate" component="/FEcomponents.production" returnvariable="makeAmount">
            <cfinvokeargument name="recipe_id" value="#ril#">
            <cfinvokeargument name="delivery_date" value="#delivery_date#">
        </cfinvoke>

        <cfset thisRecipeYield = thisRecipe.getYield()>
        <cfset thisQuantity = recipeItems.getitemQuantity()>

        <cfif thisRecipeYield neq 0>
            <cfset recipeRatio = makeAmount / thisRecipeYield>
            <cfset thisQuantity *= recipeRatio>
        </cfif>

        <cfif structKeyExists(outerstruct, theitem.getid())>
            <!--- we must add this quantity to the existing key, not create a new one --->
            <cfset outerstruct[theitem.getid()].totalToGet += thisQuantity>
        <cfelse>
            <!--- create a new struct --->
            <cfset outerstruct[theitem.getid()] = structnew()>
            <cfset outerstruct[theitem.getid()].rawMaterialid = theitem.getid()>
            <cfset outerstruct[theitem.getid()].rawMaterialName = theItem.getName()>
            <cfset outerstruct[theitem.getid()].totalToGet = thisQuantity>
            <cfset outerstruct[theitem.getid()].uom = theItem.getUOM().getname()>
        </cfif>
    </cfif>
</cfloop>
