Dynamic Picklist Values Using Metadata API
3 minute read
Very often we run into the requirement of needing dynamic picklist values in Salesforce. A common solution involves getting picklist values through the getDescribe method. The values are then used in VisualForce pages or custom controllers. However, having customized VisualForce page instead of a standard page layout, is not always an option.
Interesting code parts for adding and deleting can be found in the addPicklistValue, and deletePicklistValue methods. MetadataService.MetadataPort object is created first. The existing picklist is read as a custom field through the readMetadata method. Picklist value is added/deleted, and the whole custom field is then updated with the updateMetadata method.
When installing the Apex wrapper for Metadata API, there are a few things to take into consideration. In order to access Metadata API in Apex code, the Apex wrapper has to be installed into the sandbox. You can find the Apex wrapper, for example, in https://github.com/financialforcedev/apex-mdapi. Click the “Deploy to Salesforce” button and deploy the package into your sandbox.
