            Some points which may help:

            • The import process is going to try to load existing data based on all four attributes in import_id_fields
            • It will then compare all fields from your Excel file (which correspond to attributes in FormatClass) with what is persisted, and if any of them do not match, it will report an 'update'
            • Set a breakpoint here to catch which field it thinks has changed.

            If I understand correctly, you want to select a value from a dropdown and have that inserted for all rows. This means that if there is a value for 'Jahr' in the import file, this will be ignored in favour of the value selected from the dropdown.

            Setting an import field to the selection in the dropdown can be achieved by assigning the value of the dropdown onto the instance of the object to be imported as follows. (I've used the single field 'year' instead of 'Jahr' and 'Kalenderwoche' but you can update your implementation along the same lines).

            django-import-export won't do this for you by default, but you can easily add some hooks to achieve this.

            You can track the id of each row imported or updated, and then delete any others at the end of the import.

            The default field for identifying whether an object exists or not is called 'id'. However you can override using import_id_fields, so in your case the following should work:

            Asked 2021-Dec-09 at 13:34

            I have a form which enables a user to register on our website. Now I need to export all the data to excel, so I turned towards the import-export package. I have 3 models, Customer, Reference and Contact. The latter two both have a m2m with Customer. I also created Resources for these models. When I use Resource().export() at the end of my done() method in my form view, it exports all existing objects in the database, which is not what I want.

            I tried googling this and only got one result, which basically says I need to use before_export(), but I can't find anywhere in the docs how it actually works.
