This post originally appeared on the SynoLab blog hosted by Synolia, an Elite SugarCRM Partner. Yann Bergès describes how you can use a relate filter with the Filter API. He also explores how Sugar does it as well as identifying a drawback to be considered when using this feature.
We all know the moment when you are roaming through source code to find something for a particular purpose and you come across that feature you didn’t expect but you absolutely want to test. This is how I came into the related link filter feature. What do I mean by related link filter? It is a derivative way to filter related data on a One-to-Many relationship by specifying a link name and a target field:
I want all Contacts filtered on their related Account with « Industry » value « Electronics » (use « one » side of the relationship)
I want all Accounts filtered on their related Contacts with « Title » value « President » (use « many » side of the relationship)
This is an advanced use of Sugar 7 Filter API, if you never used it before, have a look at this documentation for detailed information about how filters work:
– SugarCRM Cookbook – The School of REST – Part 3
– Sugar 7.8 Developer Guide – Architecture – Filters
Examples and tests have been made with a Sugar instance PRO 188.8.131.52
