How to dynamically change resource class in Django Import-Export admin based on user group?

Question

I am using Django Import-Export library to manage export functionalities in my Django admin interface. I have a requirement where I need to dynamically change the resource class based on the user's group membership.

Here's a simplified version of what I am trying to achieve:

    from import_export.admin import ImportExportModelAdmin
    from django.contrib import admin
    from .resources import RawFileDMDResource, RawFileResource
    
    class RawFileAdmin(ImportExportModelAdmin):
        resource_class = RawFileResource
        [...]
        def get_resource_class(self, request=None):
            resource_class = self.resource_class
            if request is None:
                user = get_user()
            else:
                user = request.user
    
            if user.groups.filter(name='DMD ext_users').exists():
                resource_class = RawFileDMDResource
            return resource_class

However, the get_resource_class method expects a request argument. It seems that the Import-Export library doesn't provide the request object in the context of this method.

Is there a way to access the current user's information or request object within the get_resource_class method without explicitly passing the request object?

Answer 1

Unfortunately it is not easy to do this with the current codebase.

One option would be to override the entire export_action() method so that you can add code to make selections based on the request instance.

For example, you could pass the request into get_export_resource_classes().

You can then override get_export_resource_classes() and add your selection logic there.

It would be a lot easier to return a Resource class based on request properties if this were passed into the method. I have raised an issue for this to be implemented. Feel free to submit a PR if you use this approach.
