Question

当我在服务器上运行脚本时，我很需要你的帮助来弄清楚为什么会出现这个错误。服务器运行一个postgres数据库我认为它与迭代的数据的对象类型有关，但不知道如何解决这个问题。

帮助将非常感谢。谢谢

Answer 1

问题在于这一行

enrolments = Enrolment.objects.filter(intervention=intervention, household__name__in=households):

household是Household个实例的查询集，而不是名称。我认为以下任何一种都可行。

enrolments = Enrolment.objects.filter(intervention=intervention, household__in=hh_name) 


enrolments = Enrolment.objects.filter(intervention=intervention, household__name__in=hh_name)

如果您使用第二个，那么您可以从代码中删除households查询集。

django.db.utils.ProgrammingError：运算符不存在：字符变化=整数
