将小部件链接到查询的数据源时遇到麻烦 [英] Had trouble linking widget to a queried datasource
问题描述
我确定每个人都已经知道这一点，但是花了我一段时间才弄清楚，所以我想我会分享.
I'm sure everyone already knows this, but it took me a while to figure out so I thought I would share.
基本上，我试图告诉小部件根据模型中条目的当前状态更改颜色.
Basically I was trying tell a widget to change color based on the current status of an entry in my model.
但是我需要将小部件1更改为201房间，将小部件2更改为202房间，等等.
But I needed Widget 1 to change for Room 201, Widget 2 to change for Room 202, etc.
例如:
房间:201，状态:可用=小部件1:绿色 房间:202，状态:已预订=小部件2:红色
Room: 201, Status: Available = Widget 1: Green Room: 202, Status: Booked = Widget 2: Red
我可以让小部件更改颜色(这要感谢 Project List Sample )，但是我很困惑如何将其单独的数据源更改为查询.它们基本上只会显示与数据库/表中当前所选项目相对应的颜色.
I could get the widgets to change color (thanks to borrowing from the code in the Project List Sample), but I was confused how to change their individual datasources to a query. They would basically only show the color corresponding to the currently selected item in the database/table.
所以，这就是我所做的:
So, here is what I did:
进入我的模型，进入数据源下，并添加了一个新的数据源.
Went into my Model, went under Datasources and added a new Datasource.
姓名:Room201
Ex name: Room201
然后在查询"构建器中的我试图缩小的字段"中.
Then in the Query builder I put in the Field I was trying to narrow by.
例如:Room =:查询
ex: Room = :Query
(房间=我的字段，并且我相信:Query"是查询的唯一名称，如果我错了，有人可以纠正我)
(Room = my field, and I believe the ":Query" is the just name of the query, someone can correct me if I'm wrong)
然后，您将在该窗口下方看到一个框，您可以在其中添加绑定.所以这就是我输入查询的地方.
Then you'll see a box below that window where you can add a binding. So THAT is where I put in my query.
例如:@ datasources.Facilities.query.filters.Room._equals = 201
ex: @datasources.Facilities.query.filters.Room._equals = 201
(注意:我必须为每个房间创建一个单独的数据源)
(Note: I had to create a separate Datasource for each room)
然后我转到我的窗口小部件，然后为数据源选择查询的数据源(Room201).
Then I went to my widget and chose the queried datasource (Room201) for the datasource.
因此，小部件1 =数据源Room201，小部件2 =数据源Room202，等等
So Widget 1 = the datasource Room201, Widget 2 = the datasource Room202, etc.
完成.
