我已实施了“ 许多多功能” 关系, 允许在 Python/ Django < / a > 中重复多个条目 。 我也有表格, 使用模型MultipleChoice Field 处理此关系, 以便验证来自ajax 请求的数据, 但形式是_ valid () 调用后, 模式MultipleChoice 字段中的任何重复项目将被删除 。 是否有办法保留重复项目( 我对表格的提交不感兴趣, 因为不在网页上使用), 或者我必须手动处理此请求 。
modelMultipleChoice Field 使用内部的查询设置,所以每个项目只出现一次(只要在数据库查询中不使用 join s,但对于这个问题无论如何都无法实现)。 您可以尝试使用简单的 MultipleChoice Fielding 并构建 choices 手工复制必要的值。
