I'm trying to import data from a CSV file to my Django database but whenever I tried to import I got "KeyError: 'id'" although there's no "id" field in my model. I'm this issue only when I using PostgreSQL, there's no error when I import the same data in sqlite3.

Solution 1:^[1]

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.

Solution 2:^[2]

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

Solution 3:^[3]

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
