[英]Extjs hasone association
I have Person model, it contains id, first_name, last_name etc and merital_id field. 我有Person模型,它包含id,first_name,last_name等和merital_id字段。 I also have Merital model contains only 2 field: id and title.
我也有Merital模型只包含2个字段:id和title。 Server responses JSON like:
服务器响应JSON如:
{
success: true,
items: [
{
"id":"17",
"last_name":"Smith",
"first_name":"John",
...
"marital_id":1,
"marital": {
"id":1,
"title":"Female"
}
},
...
]
}
So how can I connect my models with association? 那么如何将我的模型与关联联系起来呢? I still can use record.raw.merital.title in my column.renderer, but I cannot use such fields in templates like {last_name} {first_name} ({merital.title}).
我仍然可以在我的column.renderer中使用record.raw.merital.title,但我不能在像{last_name} {first_name}({merital.title})这样的模板中使用这些字段。 What king of association do I need to use, I tryed belongsTo, but when I try to use record.getMarital() I get an error "no such method on record".
我需要使用什么样的关联王,我尝试使用belongsTo,但是当我尝试使用record.getMarital()时,我得到一个错误“记录中没有这样的方法”。
I use extjs 4 我使用extjs 4
You should be using ExtJS Models, and Associations, in particular the HasOne association. 您应该使用ExtJS模型和关联,特别是HasOne关联。
