[brindakv]

User should not be able to see or edit the following columns in the Accession_Code table:

• PDB Extended Code
• PDB Code
• PDB Accession Code
• Accession Serial
• Notes

@svoinea Please use following snippet for ACL update

cnames = ["Accession_Serial", "PDB_Extended_Code", "PDB_Code", "PDB_Accession_Code", "Notes"]
    for cname in cnames:
        col = table.columns[cname]
        col.acls.update({
            "enumerate": {},
            "select": g["entry-updaters"],        
            "insert": g["entry-updaters"]
        })
