Unable to get related model data in dump_bulk method

[jatindergit]

Hi
I have following models:

class ClientLevel(TimeStampModel):
    name = CICharField(_('Name'), max_length=50)
    client = models.ForeignKey(Client, related_name='client_levels', on_delete=models.CASCADE)
    order = models.PositiveSmallIntegerField(_('Display Order'))`


class ClientDivision(AL_Node, TimeStampModel):
    name = models.CharField(max_length=50)
    parent = models.ForeignKey('self', related_name='children_set', null=True, db_index=True,
                               on_delete=models.DO_NOTHING)
    level = models.ForeignKey(ClientLevel, on_delete=models.PROTECT, related_name='client_level_divisions')
    client = models.ForeignKey(Client, related_name='client_divisions', on_delete=models.CASCADE)
    node_order_by = ['name']

Issue is, I want to fetch level__order field value in dump_bulk method. How can I do this. Please help

I have the same issue.

With the following models:

class Customer(models.Model):
    email = models.EmailField(unique=True)

class BaseAsset(models.Model):
    name = models.CharField(max_length=INLINE_MAX_LENGTH, blank=True, default="")
    type = models.CharField(max_length=INLINE_MAX_LENGTH, blank=True, default="")
    description = models.TextField(blank=True, default='')


class Asset(MP_Node, BaseAsset):
    customer = models.ForeignKey('Customer', null=True, blank=True, on_delete=models.SET_NULL)

the .dump_bulk() function returns this:

[
    {
        "data": {
            "customer": 1
        },
        "baseasset_ptr_id": 1,
        "children": [
            {
                "data": {
                    "customer": 1
                },
                "baseasset_ptr_id": 4,
                "children": [
                    {
                        "data": {
                            "customer": 1
                        },
                        "baseasset_ptr_id": 6
                    },
                    {
                        "data": {
                            "customer": 1
                        },
                        "baseasset_ptr_id": 7
                    }
                ]
            },
            {
                "data": {
                    "customer": 1
                },
                "baseasset_ptr_id": 5
            }
        ]
    },
    {
        "data": {
            "customer": 1
        },
        "baseasset_ptr_id": 8
    },
    {
        "data": {
            "customer": null
        },
        "baseasset_ptr_id": 9
    }
]

And the admin view shows this structure:

dump_bulk just uses Django's built-in serializers to serialize your model data - which will just provide the ID of related objects by default. Your use case is very specific, so will have to do a bit of work to handle it. Options include:

• Post-process the generated output to add additional data (order in this case), by fetching it using the ID that has already been exported. This is probably the easiest and should be relatively straightforward to do.
• Provide your own python serializer which does what you need.
• Use a different utility (e.g., django rest framework) which provides more flexible serialization tools.
