How to filter and get all vendor details using category

[Gautam Ankul]

Here is my models

class Vendor(models.Model):

category_id = models.ForeignKey(

Category,

blank=True,

null=True,

verbose_name=u"Category id",

on_delete=models.CASCADE,

)

vendor_id = models.CharField(

unique=True, max_length=50, blank=False, null=False, verbose_name=u"Vendor Id",

)

vendor_name = models.CharField(

max_length=50, blank=False, null=False, verbose_name=u"Vendor name"

)

vendor_password = models.CharField(

max_length=50, blank=False, null=False, verbose_name=u"Vendor password"

)

vendor_avg_rating = models.DecimalField(

validators=[MinValueValidator(0.0), MaxValueValidator(5.0)],

max_digits=3,

decimal_places=2,

blank=True,

null=True,

verbose_name=u"Vendor average rating",

)

vendor_tokens = models.TextField(

default="[]", blank=True, null=True, verbose_name=u"Vendor tokens",

for category:

class Category(models.Model):

category_name = models.CharField(

max_length=50, blank=False, null=False, verbose_name=u"Category name"

)

def __str__(self):

return self.category_name

class Meta:

verbose_name_plural = "Categories"

and serializer is here

class VendorSerializer(serializers.ModelSerializer):

class Meta:

model = Vendor

fields = ["vendor_id","vendor_name","vendor_location"]

and i want that type of result:

{
    "ErroeCode": "0",
    "status": 200,
    "message": "Get vendor details successfully",
    "Items": [
        {
            "vendor_id": "1",
            "vendor_name": "ankul gautam"
        },
        {
            "vendor_id": "2",
            "vendor_name": "deepak kush"

Hi,

You need to create a Category serializer an append it to VendorSerializer

class CategorySerializer(serializers.ModelSerializer):

    class Meta:

        model = Category

        fields = ["category_name", ]

class VendorSerializer(serializers.ModelSerializer):

    category = CategorySerializer()

    class Meta:

        model = Vendor

        fields = ["vendor_id", "vendor_name", "vendor_location", "category"]

You can filter by category now.

Regards,
