Question

我是Django的新手，正在构建测验应用程序。我希望能够使用管理站点上的import_export.admin方法从Django中的CSV文件导入一些问题，当我尝试导入时，包含问题列表的CSV文件的内容不会追加到现有文件中问题列表相反，它引发错误“以10为底的'int（）无效文字：'独立'。”

我尝试将要上传的CSV文件的格式从逗号分隔的值更改为CSV UTF-8（逗号分隔）。我还尝试在“类别”列中使用整数，但是它给出了“回溯（最近一次呼叫最近）类别匹配查询不存在”错误。有帮助吗？

我的admin.py文件：

class QuizAdmin(admin.ModelAdmin):
     form = QuizAdminForm
     list_display = ('title', 'category', )
     list_filter = ('category',)
     search_fields = ('description', 'category', )


class CategoryAdmin(admin.ModelAdmin):
     search_fields = ('category', )

class MCQuestionAdmin(ImportExportModelAdmin):
      list_display = ('content', 'category', )
      list_filter = ('category',)
      fields = ('content', 'category',
      'figure', 'quiz', 'explanation', 'answer_order')
       search_fields = ('content', 'explanation')
      filter_horizontal = ('quiz',)
      inlines = [AnswerInline]

我的models.py文件：

class CategoryManager(models.Manager):

  def new_category(self, category):
    new_category = self.create(category=re.sub('\s+', '-', category).lower())
    new_category.save()
    return new_category

在创建问题时，对于类别，应使用现有类别的ID，而不是字符串值或随机整数。

您已经创建了一些类别吗？
