Adding Namespace to the code

Question

While moving code from developer org to packaging org using ANT in few places of the apex code we need to prefix the packaging namespace. Is there any way to automate this process?

For instance:

RecordType Test = [
    SELECT Id, Name
    FROM RecordType
    WHERE SobjectType = 'abc__books__c'
    AND DeveloperName = 'bookreview'
]; 

In the above code abc is the namespace which is added manually.

Answer 1

There are several ways to achieve this:

1. Querying the namespaceprefix. You can perform query on ApexClass to find if namespace exist or not. eg. ApexClass cs =[select NamespacePrefix from ApexClass where Name =:'<name of the class from your package>'];

2. Create a field in custom setting(Hierarchy) which will contain the namespaceprefix. Hierarchy type custom setting record can be retrieved without using queries.

3. One more nice approach is using custom metadata types. Actually they have namespaceprefix standard field which auto populates in namespaced environment.With custom metadata types, you can issue unlimited Salesforce Object Query Language (SOQL) queries for each Apex transaction.

I think you need to create a common class where you declare the namespace as private variable like this:

private static String NAMESPACE_PREFIX='abc';

Then you use this variable wherever you need this prefix like in your case:

String sObject = NAMESPACE_PREFIX+'books__c'; String devName = books; String qry = '[select Id,Name from RecordType where SobjectType = :sObject and DeveloperName = :devName]

Hope it helps you
