Question

任何帮助都将不胜感激，因为我正在用这根头发拔头发！我有一个Formview，它发送了repair_id和part_id到ModelForm。 ModelForm将此数据用作ModelChoiceField的输入，以提取一组值。我将ModelChoiceField子类化为PartMatModelChoiceField，以连接标签中的两列。这一切似乎都可以正常工作，但是每次我提交表单时，这些东西都不会提交为有效。

如果我查看html输出，则表单值/标签正确显示。如果我从ModelChoiceField中获取一个值，然后通过外壳提交表单，那么一切将显示为有效且没有错误。

测试一段时间后，我可以看到问题出在part_mat_nr字段上。

如果我将其切换回ModelChoiceField（无子类），则遇到相同的问题如果我将查询集简化为PrdTtBom.objects.filter（item_no__iexact = part_id），我也会遇到同样的问题如果我用静态设置的part_id替换了简化查询集中的变量part_id。有用。

此变量正在正确构建列表中，因此无法确定。

Model.py（相关字段）

part_mat_nr = models.CharField(db_column='Part_Mat_Nr', max_length=255, verbose_name='Part Number')

具有ModelChoiceField的Django ModelForm似乎不适用于参数
