Default field set differs during import in v4

[matthewhegarty]

Describe the bug

in v3, all model fields are presented during import:

In v4, only certain model fields are presented, even when no fields attribute is defined.

To Reproduce

Import the books.csv file using the Admin console.

Versions (please complete the following information):

• Django Import Export: 4.0.1
• Python 3.11
• Django 5.0.2

Expected behavior

For consistency with v3, we should see all default fields presented.

@matthewhegarty I could not reproduce this. You mention importing books.csv but screenshot looks like E-books import (it has author field). Without digging deeper, it seems fields that are presented are defined with Resource class and not import file headers.

Ah good point - thanks for checking. I'll check again later and close if I cannot reproduce.

Yes, it looks ok when importing a file to Book
