如何在管理页面上修改django import export软件包

Question

我正在使用Django Import导出通过管理页面导入书籍列表。我想知道是否可以自定义Django Admin页面，以便它为用户可以选择的月份字段提供一个模型选择字段

Models.py：

from django.db import models

class Author(models.Model):
    name = models.CharField(max_length=100)

    def __str__(self):
        return self.name


class Category(models.Model):
    name = models.CharField(max_length=100)

    def __str__(self):
        return self.name


class Book(models.Model):
    JANUARY = '1'
    FEBRUARY = '2'
    MARCH = '3'
    APRIL = '4'
    MAY = '5'
    JUNE = '6'
    JULY = '7'
    AUGUST = '8'
    SEPTEMBER = '9'
    OCTOBER = '10'
    NOVEMBER = '11'
    DECEMBER = '12'

    MONTH_CHOICES = (
        (JANUARY, 'January'),
        (FEBRUARY, 'February'),
        (MARCH, 'March'),
        (APRIL, 'April'),
        (MAY, 'May'),
        (JUNE, 'June'),
        (JULY, 'July'),
        (AUGUST, 'August'),
        (SEPTEMBER, 'September'),
        (OCTOBER, 'October'),
        (NOVEMBER, 'November'),
        (DECEMBER, 'December'),
    )

    name = models.CharField('Book name', max_length=100)
    author = models.ForeignKey(Author, models.SET_NULL, blank=True, null=True)
    author_email = models.EmailField('Author email', max_length=75, blank=True)
    imported = models.BooleanField(default=False)
    published = models.DateField('Published', blank=True, null=True)
    price = models.DecimalField(max_digits=10, decimal_places=2, null=True, blank=True)
    categories = models.ManyToManyField(Category, blank=True)
    month = models.CharField(
        max_length=2,
        choices= MONTH_CHOICES,
        default=JANUARY,
    )


    def __str__(self):
        return self.name

admin.py

from django.contrib import admin
from import_export import resources
from .models import *
from import_export.admin import ImportExportModelAdmin
from import_export.fields import Field
from import_export.fields import *
from import_export.widgets import *
from django.dispatch import receiver
from import_export.signals import post_import, post_export
from import_export.admin import ImportExportActionModelAdmin

class BookResource(resources.ModelResource):

    class Meta:
        model = Book
        import_id_fields = ('name','month',)
        fields = ('name', 'price','month')



@admin.register(Book)
class BookAdmin(ImportExportActionModelAdmin):
    resource_class = BookResource


admin.site.register(Author)
admin.site.register(Category)

除了要导入和格式化的文件外，我还想添加月份选择字段，因此它会根据选择添加月份。我的问题是该包装是否可行？
