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??
