What's the best way to check if a page doesn't have child/ren

#1

Matrix Version:5.3.4

In SOAP API, there is a method getChildren which will give me all the children of an asset. Unfortunately this will give me also all children that is part of the asset (content container etc).

I need to check whether an asset is the last in the asset lineage (ie, doesn’t have any “children”). What is the best way to do that? I know I can pass on type_code when I call getChildren but then I will need to make calls as many as all possible type_code.

Thanks for your help.

Have you tried setting this parameter to FALSE?

Dependant: indicates whether to return assets that are dependently linked to the specified asset ID or only non-dependant assets. The value for this parameter should be either TRUE (dependant) or FALSE (non-dependant) (or 1 or 0). The default value for this parameter is NULL.

Thank you for your reply @mfong. I have tried that but it still doesn’t give me what I need.

Setting Dependent = 1 gives me:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="qheps">
   <SOAP-ENV:Body>
      <ns1:GetChildrenResponse>
         <GetChildrenResult>
            <AssetID>331614</AssetID>
            <TypeCode>bodycopy</TypeCode>
         </GetChildrenResult>
         <GetChildrenResult>
            <AssetID>331616</AssetID>
            <TypeCode>content_type_wysiwyg</TypeCode>
         </GetChildrenResult>
         <GetChildrenResult>
            <AssetID>1680619</AssetID>
            <TypeCode>bodycopy</TypeCode>
         </GetChildrenResult>
         <GetChildrenResult>
            <AssetID>331615</AssetID>
            <TypeCode>bodycopy_div</TypeCode>
         </GetChildrenResult>
         <GetChildrenResult>
            <AssetID>1680621</AssetID>
            <TypeCode>content_type_wysiwyg</TypeCode>
         </GetChildrenResult>
         <GetChildrenResult>
            <AssetID>1680620</AssetID>
            <TypeCode>bodycopy_div</TypeCode>
         </GetChildrenResult>
      </ns1:GetChildrenResponse>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

While setting Dependant = 0 gives me:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="qheps">
   <SOAP-ENV:Body>
      <ns1:GetChildrenResponse>
         <GetChildrenResult>
            <AssetID>331616</AssetID>
            <TypeCode>content_type_wysiwyg</TypeCode>
         </GetChildrenResult>
         <GetChildrenResult>
            <AssetID>340026</AssetID>
            <TypeCode>folder</TypeCode>
         </GetChildrenResult>
         <GetChildrenResult>
            <AssetID>1680617</AssetID>
            <TypeCode>folder</TypeCode>
         </GetChildrenResult>
         <GetChildrenResult>
            <AssetID>1680618</AssetID>
            <TypeCode>page_standard</TypeCode>
         </GetChildrenResult>
         <GetChildrenResult>
            <AssetID>1680620</AssetID>
            <TypeCode>bodycopy_div</TypeCode>
         </GetChildrenResult>
         <GetChildrenResult>
            <AssetID>331615</AssetID>
            <TypeCode>bodycopy_div</TypeCode>
         </GetChildrenResult>
         <GetChildrenResult>
            <AssetID>1680621</AssetID>
            <TypeCode>content_type_wysiwyg</TypeCode>
         </GetChildrenResult>
         <GetChildrenResult>
            <AssetID>331614</AssetID>
            <TypeCode>bodycopy</TypeCode>
         </GetChildrenResult>
         <GetChildrenResult>
            <AssetID>340027</AssetID>
            <TypeCode>folder</TypeCode>
         </GetChildrenResult>
         <GetChildrenResult>
            <AssetID>1680619</AssetID>
            <TypeCode>bodycopy</TypeCode>
         </GetChildrenResult>
      </ns1:GetChildrenResponse>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

It seems that the following always returned regardless the value of Dependant:

 <GetChildrenResult>
    <AssetID>331616</AssetID>
    <TypeCode>content_type_wysiwyg</TypeCode>
 </GetChildrenResult>

That’s weird, what happens if you also se the MaxDepth to 1 ? So, just get children that are direct children of the current asset?

You could also try using the JS API get children function perhaps?

https://matrix.squiz.net/manuals/web-services/chapters/javascript-api#getChildren

Also, any reason why you couldn’t just use a dynamic asset listing?

Thanks @Bart. Using MaxDepth = 1 helps. I got the following:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="qheps">
   <SOAP-ENV:Body>
      <ns1:GetChildrenResponse>
         <GetChildrenResult>
            <AssetID>331614</AssetID>
            <TypeCode>bodycopy</TypeCode>
         </GetChildrenResult>
         <GetChildrenResult>
            <AssetID>340026</AssetID>
            <TypeCode>folder</TypeCode>
         </GetChildrenResult>
      </ns1:GetChildrenResponse>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

So I guess if I got only one children type of bodycopy then this asset basically doesn’t have ‘children’. Do you think that logic holds?

Yep, sounds pretty good.
