django.import-export ImportExportMixin customisation

I am using ImportExportMixin to add the import export buttons to my admin page:

i write it like this :

from django.contrib import admin
from .models import *
from import_export.admin import ImportExportMixin

class PlayerAdmin(ImportExportMixin,admin.ModelAdmin):
    list_display = [field.name for field in Player._meta.fields]

admin.site.register(Player,PlayerAdmin)

When I do th export I get something like this :

[{"id": 1, "name": "player1", "date_birth": "1997-01-01", "tshirtnumber": 19, "club": 1, "poste": "ST"}]

The club is a ForeingKey and I want the name of the club not the id. so what to do ? and please I need the same thing for the import I mean I want to import players with their club name .

I am expecting :

[{"id": 1, "name": "player1", "date_birth": "1997-01-01", "tshirtnumber": 19, "club": "chelsea", "poste": "ST"}]

For export you can define the relation in the fields list of your resource:

class PlayerResource(ModelResource):
    class Meta:
        model = Player
        # add all your export fields
        fields = ("id", "name", "club__name")

For importing relations, declare a ForeignKeyWidget:

class PlayerResource(ModelResource):
     # values here might be different depending on your model
     club = fields.Field(
        column_name='club',
        attribute='club',
        widget=ForeignKeyWidget(Club, field='name'))


    class Meta:
        model = Player
        # ...
