Can someone help on the UX TriModal CRUD(add, create,delete, update records). I tried the regular expression given in the documentation (/{dataSourceName}/{recordId})*/{dataSourceName} but doesn't work. It keeps saying invalid regular expression. Can we get a detailed example on how to add new records to the UX dataSource, update, delete from the dataSource?

Hi Olayinka, i am not a specialist on the subject but saw there were no replies yet so figured I would try to help you find anything useful. 

So I found the following and hope it might at least give you some ideas on how to solve your issue...

Regular expressions are typically used for pattern matching, but CRUD operations involve more than just pattern matching.  The regular expression you mentioned (/{dataSourceName}/{recordId})*/{dataSourceName}) might not be directly related to CRUD operations. 

Found the following in regards to creating a record:
def create_user(name, email):
    # Create a new User record in the dataSource
    # Save the provided name and email
    # Return success or failure status
