我一直试图让 django-import-export 与我网站的管理页面一起工作，但遇到了砖墙。目前我正在使用一个空数据库（模式是从模型创建的，但没有添加数据）。“导出”按钮似乎可以正常工作，但单击导入按钮会引发 TypeError，我终生无法破译。这里是：

如果它有帮助，我尝试通过manage.py shell（参考文档）导入，并且它有效。这是我所做的：
import tablib
from import_export import resources
from new_bridge.models import *
book_resource = resources.modelresource_factory(model=WordTable)()
dataset = tablib.Dataset(['1', 'title'], headers=['id','title'])
result = book_resource.import_data(dataset, dry_run=False)
print result.has_errors()
False
这是有问题的模型（来自models.py）：
class WordTable(models.Model):
id = models.IntegerField(primary_key=True)
title = models.CharField(db_column='TITLE', max_length=17, blank=True)
def __unicode__(self):
return self.title
class Meta:
managed = True
db_table = 'word_table'
...以及 manage.py 的相关部分：
from django.contrib import admin
from import_export.admin import ImportExportModelAdmin
from import_export import resources
from new_bridge.models import WordTable
class WordTableResource(ImportExportModelAdmin):
class Meta:
model = WordTable
fields = ('title')
class WordTableAdmin(ImportExportModelAdmin):
fields = ['title']
resource_class = WordTableResource
pass
# Register models w admin to make them editable:
admin.site.register(WordTable, WordTableAdmin)
这真的让我陷入了一个循环。任何帮助将非常感激。
