Custom Response to display the data in list of JSON using django-CodePudding

models.py

class Project(models.Model):
    project_id = models.CharField(max_length=50,default=uuid.uuid4, editable=False, unique=True, primary_key=True)
    org = models.ForeignKey(Organisation, on_delete=models.CASCADE, related_name='org_project',null=True)
    product = models.ManyToManyField(Product,related_name='product_project')
    client = models.ForeignKey(Client, on_delete=models.CASCADE, related_name='client_project')
    project_name = models.CharField(unique=True,max_length=100)
    project_code = models.CharField(max_length=20)
    project_cost = models.IntegerField(null=True)
    currency_type = models.CharField(max_length=100, choices=CURRENCY_CHOICES, default='Indian Rupee')
    project_head = models.ForeignKey(User_Master, on_delete=models.CASCADE, related_name='project_head',null=True)
    project_manager = models.ForeignKey(User_Master, on_delete=models.CASCADE, related_name='project_manager',null=True)
    project_user = models.ManyToManyField(User_Master,related_name='project_user')
    description = models.TextField(max_length=500)
    start_date = models.DateField()
    end_date = models.DateField()
    techstack = models.ManyToManyField(Techstack,related_name='techstack_project')
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)
    is_active = models.IntegerField(default=0, choices=STATUS_CHOICES)

views.py

from djmoney.settings import CURRENCY_CHOICES

class CurrencyList(APIView):
    renderer_classes = (CustomRenderer,)

    def get(self, request, *args, **kwargs):
        return Response(CURRENCY_CHOICES, status=status.HTTP_200_OK)

I was Trying to get the Currency code list in a response so that the data can be sent to the frontend as a dropdown list.

When I Used the above django money package I am getting an response as

{
    "status": "success",
    "code": 200,
    "data": [
        [
            "XUA",
            "ADB Unit of Account"
        ],
        [
            "AFN",
            "Afghan Afghani"
        ],
        [
            "AFA",
            "Afghan Afghani (1927–2002)"
        ],
        ....
],
    "message": null
}

But I need to Get the response as list of json inside the data not as the list of arrays,

{
    "status": "success",
    "code": 200,
    "data": [
        {
            "shortname": "XUA",
            "fullname": "ADB Unit of Account"
        },
        {
            "shortname":"AFN",
            "fullname":"Afghan Afghani"
        },
        {
            "shortname":"AFA",
            "fullname":"Afghan Afghani (1927–2002)"
        },
        ....
],
    "message": null
}

Is it possible to modify the response for this package? or is there any other way to achieve the end goal response by any other method?

CodePudding user response：

You just need to adjust your response in the following way:

from djmoney.settings import CURRENCY_CHOICES

class CurrencyList(APIView):
    renderer_classes = (CustomRenderer,)

    def get(self, request, *args, **kwargs):
        return Response(
            [{'shortname': short, 'fullname': full} for short, full in CURRENCY_CHOICES],
            status=status.HTTP_200_OK,
    )

CodePudding user response：

try this

from djmoney.settings import CURRENCY_CHOICES

class CurrencyList(APIView):
    renderer_classes = (CustomRenderer,)

    def get(self, request, *args, **kwargs):
        return Response([dict(zip(['shortname', 'fullname'], c)) for c in CURRENCY_CHOICES], status=status.HTTP_200_OK)

python console

>>> data = [
...         [
...             "XUA",
...             "ADB Unit of Account"
...         ],
...         [
...             "AFN",
...             "Afghan Afghani"
...         ],
...         [
...             "AFA",
...             "Afghan Afghani (1927–2002)"
...         ]
         ]
>>> 
>>> [dict(zip(['shortname', 'fullname'], c)) for c in data ]
[{'shortname': 'XUA', 'fullname': 'ADB Unit of Account'}, {'shortname': 'AFN', 'fullname': 'Afghan Afghani'}, {'shortname': 'AFA', 'fullname': 'Afghan Afghani (1927–2002)'}]
