As I can display forms in my view with OneToOneField relationships?
I was trying to create a relationship with EgresoMesual Pacientee, going by the GET method creates me the form
But to go through the POST method and relate the form EgresoMensualForm
egreso_form = EgresoMensualForm (self.request.POST, instance = request.paciente.egresomensual)
I mark error:
AttributeError at / ece / file /
'WSGIRequest' object has no attribute 'patient'
How can I create a single form that takes models: EgresoMensual, OtrosIngresos, Holiday Observations
