How to merge two Querysets and create new queryset in django - django

Question

I have two models for two parts of AC, that is IndoorInventory for the indoor unit which shows all indoor unit information, and OutdoorInventory for showing outdoor unit information.
class IndoorInventory(models.Model):
client = models.ForeignKey(Client, on_delete=models.CASCADE)
product = models.CharField(max_length=50)
indoor_brand = models.CharField(max_length=100, null=True, blank=True)
indoor_model_no = models.CharField(max_length=100, null=True, blank=True)
indoor_sr_no = models.CharField(max_length=100, null=True, blank=True)
outdoor_model_no = models.CharField(max_length=100, null=True, blank=True)
class OutdoorInventory(models.Model):
client = models.ForeignKey(Client, on_delete=models.CASCADE)
product = models.CharField(max_length=50)
outdoor_brand = models.CharField(max_length=100, null=True, blank=True)
outdoor_model_no= models.CharField(max_length=100, null=True, blank=True)
outdoor_sr_no = models.CharField(max_length=100, null=True, blank=True)
indoor_model_no= models.CharField(max_length=100, null=True, blank=True)
I am passing a queryset of IndoorInventory to my Django template and fetching all the data there. Below is my VIEW
def clientInventory(request):
context = {}
client_id = request.GET.get('client_id')
id_inven = IndoorInventory.objects.filter(client=client_id)
od_inven = OutdoorInventory.objects.filter(client=client_id)
context['id_inven'] = id_inven
return render(request, 'client-inventory.html', context)
My Template Below
<table id="client-invent-admin" class="table table-striped table-bordered display nowrap">
<thead>
<tr>
<th class="filterhead">ID</th>
<th class="filterhead">Brand</th>
<th class="filterhead">Product/Type</th>

{% for invent in id_inven %}
{% if invent.indoor_model_no == '' %}
<tr class="bg-danger">

{% endif %}
{% endfor %}

<tfoot>
<tr>
<th>ID</th>
<th>Brand</th>

</table>
See table frontend
Now I want to get the outdoor_sr_no from OutdoorInventory models and pass it to the IndoorInventory Queryset so that the outdoor_sr_no value also get fetched on the table next to (OD model no) column in the table

Answer 1

You can use the chain method which concatenates the querysets
from itertools import chain
result_list = list(chain(q1, q2, q*))
The chain method returns a chained object, so you transform it into a list and then you can get the information.
You can also use the union method (Django Union Method)
qs1.union(qs2)
See more information in How can I combine two or more querysets in a Django view?

Answer 2

In your clientInventory method, you could add od_inven to your context dict.
context['id_inven'] = id_inven
context['od_inven'] = od_inven
Then you could use that in your template in the same way you are currently using id_inven. Something like:
...
<body>
{% for foo in od_inven %}
...
<td>{{ foo.id }}</td>
...
