Django printing dynamic field in template - django

Question

With a given model:
class Ventas(models.Model):
producto = models.CharField(max_length=200, help_text="", blank=True, null=True)
stock = models.IntegerField(help_text="Tier", blank=True, null=True)
marca = models.ForeignKey(Marcas, help_text="Usuario", blank=True, null=True, on_delete=models.CASCADE)
categoria = models.ImageField(upload_to='', default="", blank=True, null=True)
def __str__(self):
return str(self.producto )
I annotate a queryset using a dynamicaly chosen field as follows:
ventas_producto = ventas.values(ver_por_choices).annotate(
uds_totales=F("uds_totales"),
share=F("uds_totales"),
).order_by('-uds_totales')
The var "ver_por_choices" can take values of the fields of the model: producto, stock, marca or categoria
Then in the template I want to print the values as
{% for venta in ventas_producto %}
<div>{{ venta.uds_totales}}</div>
<div>{{ venta.share}}</div>
{% endfor %}
How can I print the dynamic field?

Answer 1

Why not include it in the queryset as key:
ver_por_choices = 'Some field name'
ventas_producto = ventas.values(ver_por_choices).annotate(
uds_totales=F('uds_totales'),
share=F('uds_totales'),
key=F(ver_por_choices)
).order_by('-uds_totales')
or even more convenient:
ventas_producto = ventas.values(
uds_totales=F('uds_totales'),
share=F('uds_totales'),
key=F(ver_por_choices)
).order_by('-uds_totales')
Then you can usse this in the {% for … %} loop with:
{% for venta in ventas_producto %}
<div>{{ venta.key }}</div>
<div>{{ venta.uds_totales}}</div>
<div>{{ venta.share}}</div>
{% endfor %}
