Template:SetProp/RequiredBy auto

Template documentation (for the template shown above, sometimes hidden or invisible)

Description

This helper-template is used, by {{SetProp}}, to automatically create a reverse-relationship, between the Properties RequiresObj, RepairedWith or RequiresTech of pages, with the current page.

It does this by checking for the provided page-name as value in either of these properties on any page in the main-name-space using a SMW-Query like:

{{#ask: [[:+]] [[RequiresObj::~{{{page}}};*]] OR [[:+]] [[RepairedWith::~{{{page}}};*]] OR [[:+]] [[RequiresTech::{{{page}}}]] }}

If it finds any results, then it sets Property:RequiredBy for the current page using these results as value.

It uses {{#arraymap:}} as a wrapper to inject these values in {{#set:RequiredBy=<value>}}.

Syntax

Type the below code somewhere in {{SetProp}} or any-other code:

{{SetProp/RequiredBy auto
|page={{{SUBPAGENAME}}}
|sep={{{sep|,}}}
}}
