Forms Canvas PowerApp表单无法从自定义连接器获取字段,该连接器从REST API返回表格数据
我创建了restapi的自定义连接器,它返回表格数据。我在canvas powerapp中将其用作数据源,它将来自自定义连接器的记录存储到集合中。此集合被成功显示每个项目的项目和属性的库用作数据源。但是,当我尝试使用集合作为数据源时,它无法访问字段。直接使用自定义连接器作为数据源也不起作用 在@aorphan的文章中,我了解到,您可以在表单中使用自定义连接器,只要它们返回表,而不是操作。据我所知,收集的内容是表格数据: 甚至集合的列也可以作为Gallery显示的项目的属性进行访问: 但是,即使将集合设置为新编辑表单的数据源,也无法从数据源添加任何字段: 为了防止我的数据需要更丰富的定义才能被表单正确解释,我的API返回的JSON如下所示:Forms Canvas PowerApp表单无法从自定义连接器获取字段,该连接器从REST API返回表格数据,forms,canvas,powerapps,connector,Forms,Canvas,Powerapps,Connector,我创建了restapi的自定义连接器,它返回表格数据。我在canvas powerapp中将其用作数据源,它将来自自定义连接器的记录存储到集合中。此集合被成功显示每个项目的项目和属性的库用作数据源。但是,当我尝试使用集合作为数据源时,它无法访问字段。直接使用自定义连接器作为数据源也不起作用 在@aorphan的文章中,我了解到,您可以在表单中使用自定义连接器,只要它们返回表,而不是操作。据我所知,收集的内容是表格数据: 甚至集合的列也可以作为Gallery显示的项目的属性进行访问: 但是,即

请帮助我获得正确的数据源,以便表单能够添加其字段,或者至少让我知道,如果由于某种原因无法添加字段,那么我可以继续。正式地说,集合不能用作PowerApps中表单控件的数据源。你的努力令人钦佩,看起来你几乎什么都试过了,所以我要告诉你我的小秘密。
它可能没有官方支持,因此使用风险自负
Items
属性设置为集合(您已经完成了此操作)DataSource
属性设置到集合(您已经这样做了)添加自定义卡
Default
属性设置为gallery.Selected.X
,其中“X”是要在表单中编辑的值李>
有什么帮助吗?非常感谢@SeaDude的回答,它非常全面和有用。尽管您的方法没有列在“官方”文档中,但它很有意义,我认为我们使用它是安全的。
