PR Summary

• Asset Model Association Established
  The code now has an added reference to the 'Asset' model. This is like giving the code a map to know where to find and interact with assets, which are crucial components of the software.

• Improvements to Location ID Updating
  Whenever an asset is assigned to a user during the procedure known as LDAP synchronization, the software now will also update the 'location_id'. This means the system will be able to better track where assets have been allocated, providing better organization and efficiency.
