我有两个模型:页面和部门。我在 extjs 的列表视图中显示页面,我想在列表视图中显示部门名称而不是部门 ID。我还没有真正通过 GUI 将部门添加到页面中,只能通过直接 db insert 语句,但我希望至少能够在列表视图中显示部门名称。
到目前为止,我有以下内容,这显示了 department_id
楷模
Ext.define('ExtMVC.model.Department', {
extend: 'Ext.data.Model',
fields: ['name']
});
Ext.define('ExtMVC.model.Page', {
extend: 'Ext.data.Model',
fields: ['title','body','department_id'],
associations: [
{type: 'belongsTo', model: 'Department'}
]
});
商店
Ext.define('ExtMVC.store.Pages', {
extend: 'Ext.data.Store',
model: 'ExtMVC.model.Page',
autoLoad: true,
proxy: {
type: 'rest',
url: '/admin/pages',
format: 'json'
}
});
Ext.define('ExtMVC.store.Departments', {
extend: 'Ext.data.Store',
model: 'ExtMVC.model.Department',
autoLoad: true,
proxy: {
type: 'rest',
url: '/admin/departments',
format: 'json'
}
});
列表显示
Ext.define('ExtMVC.view.page.List' ,{
extend: 'Ext.grid.Panel',
alias : 'widget.pagelist',
title : 'All Pages',
store: 'Pages',
initComponent: function() {
this.tbar = [{
text: 'Create Page', action: 'create'
}];
this.columns = [
{header: 'Title', dataIndex: 'title', flex: 1},
{header: 'Department', dataIndex: 'department_id', flex: 1}
];
this.callParent(arguments);
}
});
控制器 (fwiw)
Ext.define('ExtMVC.controller.Pages', {
extend: 'Ext.app.Controller',
init: function() {
this.control({
'pagelist': {
itemdblclick: this.editPage
},
'pagelist > toolbar > button[action=create]': {
click: this.onCreatePage
},
'pageadd button[action=save]': {
click: this.doCreatePage
},
'pageedit button[action=save]': {
click: this.updatePage
}
});
},
onCreatePage: function () {
var view = Ext.widget('pageadd');
},
onPanelRendered: function() {
console.log('The panel was rendered');
},
doCreatePage: function (button) {
var win = button.up('window'),
form = win.down('form'),
values = form.getValues(),
store = this.getPagesStore();
if (form.getForm().isValid()) {
store.add(values);
win.close();
this.getPagesStore().sync();
}
},
updatePage: function (button) {
var win = button.up('window'),
form = win.down('form'),
record = form.getRecord(),
values = form.getValues(),
store = this.getPagesStore();
if (form.getForm().isValid()) {
record.set(values);
win.close();
this.getPagesStore().sync();
}
},
editPage: function(grid, record) {
var view = Ext.widget('pageedit');
view.down('form').loadRecord(record);
},
stores: [
'Pages',
'Departments'
],
models: [
'Page'
],
views: [
'page.List',
'page.Add',
'page.Edit'
]
});
