Question

无法排除ID，甚至无法尝试使用stackoverflow中的现有问题：django-import-export: cannot exclude id field during import : KeyError: u'id'

resource.py

from import_export import resources
from .models import Bugdata

class BugDataResource(resources.ModelResource):

    class Meta:
        model = Bugdata
        skip_unchanged = True
        report_skipped = True
        exclude = ('id',)
        import_id_fields = ['Created_date', 'BugID', 'ID_Link', 'Summary', 'Status', 'Severity', 'Tags']

models.py

from django.db import models

class Bugdata(models.Model):
    Created_date = models.DateField()
    BugID = models.CharField(max_length=50,primary_key=True)
    ID_Link = models.URLField(max_length=300)
    Summary = models.CharField(max_length=600)
    Status = models.CharField(max_length=10)
    Severity = models.CharField(max_length=10)
    Tags = models.CharField(max_length=10)

    def __str__(self):
        return self.Summary

admin.py

from django.contrib import admin
from import_export.admin import ImportExportModelAdmin
from .models import Bugdata
# Register your models here.

@admin.register(Bugdata)
class NewtaskAdmin(ImportExportModelAdmin):
    pass

显然我没有添加评论的名声，您解决了吗？我在使用与您自己相同的设置时发生了类似的情况，因此建议您仔细检查您要锁定的文件的编码。在Mac上将Excel保存为CSV格式时遇到了问题，在这种情况下，我使用了sublime之类的文本编辑器来确保将其保存为UTF8格式，并且该特定错误似乎消失了。
