Hi there, i have created a website that controls a remote lab and i need every time a user logs in to execute an experiment no other user can log in to the same experiment station. All i want to do is to update a flag value in a specific table in the database. In thee controller of the experiment i added this .. db(db.Exp_Logs_Perm.id == '1').update(Current_State='1')..i ve tried update record but nothing changed and i am getting this error .
raise ValueError("No fields to update") ValueError: No fields to update i define my table inside model db.py. --> db.define_table('Exp_Logs_Perm',Field('Experiment',requires=IS_NOT_EMPTY()),Field('Info'),Field('current_state',requires=IS_NOT_EMPTY())) Does the controller executes everytime my html file for this controller is called?? -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.
