Python oracle+django+批量创建+长文本

我使用的是django 1.6.2+oracle 12+cx_oracle 5.1.2

这是我的模型

class Value(models.Model):
    text= models.TextField()

我有一些俄文文本，它的长度是3000个字符，当我尝试这样做时：

text = 'some text' #3000 characters

v = Value(text=text)
v.save()

没关系

但当我这么做的时候：

text = 'some text' #3000 characters

v = Value(text=text)
Value.objects.bulk_create([v])

我得到了一个例外：

但是对于英文字符来说没关系
