问题
I am using flask_restplus to create a documented API. The marshal decorator controls what data actually gets rendered in your response, but I am having trouble rendering the data. I have the following code:
kpis_model = api.model('kpis', {
'cpl_actual': fields.Integer(description='costo por lead total del mes actual'),
'cpl_anterior': fields.Integer(description='costo por lead total del mes anterior'),
'cpl_diferencia': fields.Integer(description='diferencia de cpl_actual y cpl_anterior')
})
@data.route('/kpis/<cliente>/<mes>/<ano>')
@data.doc(params={'cliente': 'id de Facebook del cliente','mes':'el mes que se desea usar (dos digitos)','ano':'el ano que se desea usar (cuatro digitos)'})
class Kpis(Resource):
@data.marshal_with(kpis_model)
def get(self,cliente,mes,ano):
'''sacar KPIs principales'''
data = {}
data['cpl_actual'] = 300
data['cpl_anterior'] = 100
data['cpl_diferencia'] = data['cpl_actual'] - data['cpl_anterior']
return jsonify(data)
And then when I go to the route /kpis/cliente/mes/ano it returns this:
{
"cpl_diferencia": null,
"cpl_anterior": null,
"cpl_actual": null
}
Why are the values being returned as null ? can someone help me please!
回答1:
You don't need to jsonify when using "marshal_with"
Just return "data"
return data
=)
