I created the model Z_MecialHistory to store information of the patient (*date,
patient and healthprofessional*) and it is related to the model PatientData.
The point is that, as Albert said, I need to access to the information in
the model PatientEvaluation.
After adding the function field Albert recommended to the model
PatientEvaluation
....
z_medical_history = fields.Function(fields.Many2Many(
'gnuhealth.z_medical_history',
None, None, 'Historial Medico del Paciente'),
'get_z_medical_history')
... I added the following function to PatientEvaluation model guessing that
I had to use the current patient ....
def get_z_medical_history(self, name):
pool = Pool()
Patient = pool.get('gnuhealth.patient')
return Patient.z_medical_history
But it doesnt work... I dont really understant how to the get function
should be coded to worrk...
And got the following error...
