psycopg2.InternalError: cannot execute INSERT in a read-only transaction
---------------------------------
Above is my stacktrace.
I am going to integrate with some WMS system for receiving. When user input the
PO number which is "Lodnum" then tryton "on_change" and will display the WMS
data to the list (MS SQL Server).
Background, after "on_change", I will read data from MSSQL. And insert to
Tryton postgres.
But when inserted, above error occurred.
