[Django]-Django-import-export error while importing data into database

I had a similar problem.
It is that for import django import-export uses “id” by default.
First, create a resources.py file – where you will declare settings for import and export. And as an exception, declare “id”.

resources.py

from import_export import resources
from .models import *

class PropertyAdminResource(resources.ModelResource):

    class Meta:
        model   =   PropertyModel
        exclude = ('id',)

admin.py

from .resources import *

@admin.register(PropertyModel)
class PropertyAdmin(ImportExportModelAdmin):
    resource_class  =   PropertyAdminResource
    list_display = ['Property_ID', 'Created_By', 'Last_Updated_By']

I highly recommend using resources.py – where you can modify the methods for import and export.

you need to let the resources model know your primary key, if it didn’t find it will automatically set it to ‘id’

here is an example

models.py

class Product(models.Model):
  my_id =  models.CharField(max_length=255, primary_key=True)

admin.py

from import_export.admin import ImportExportModelAdmin
from import_export import resources

class ProductAdminResource(resources.ModelResource):
    class Meta:
         model = Product
         import_id_fields = ['my_id']

@admin.register(Product)
class ProductAdminView(ImportExportModelAdmin):
    resource_class = ProductAdminResource

I had some errors like you and managed to solve them following this answer – https://github.com/django-import-export/django-import-export/issues/92#issuecomment-598009569

I changed from version 2.0.2 to 2.0.1, removed the custom primary key and migrated again

I hope this helps with your problem

Please read
https://django-import-export.readthedocs.io/en/latest/getting_started.html#customize-resource-options

So for your your model you could do

class PropertyAdminResource(resources.ModelResource):
            

    class Meta:
        model = PropertyModel
        
        import_id_fields = ('Property_ID',)
        
class PropertyModelAdmin(ImportExportModelAdmin):
    resource_class = PropertyAdminResource
        
        
admin.site.register(PropertyModel, PropertyModelAdmin)

tested with django-import-export 2.7.0
