[英]ExtJs 6.0 : Grid Cell Editing with a Combobox - Not Syncing the id value
I'm using a grid with Ext.grid.plugin.CellEditing. 我正在使用带有Ext.grid.plugin.CellEditing的网格。 On the grid, there's a combobox and a date.
在网格上,有一个组合框和一个日期。 The date is syncing correctly, but the combobox is trying to save the id of the combobox in a String description field.
日期正确同步,但是组合框正在尝试将组合框的ID保存在字符串描述字段中。
My combobox has fields codeChecklistItemStatusId (foreign key), and codeChecklistItemStatus (display field for user). 我的组合框具有字段codeChecklistItemStatusId(外键)和codeChecklistItemStatus(用户显示字段)。
When I edit the Checklist Item Status field, the field I've chosen for display field (dataIndex: 'codeChecklistItemStatus') is updated to be an integer. 当我编辑Checklist Item Status字段时,我为显示字段选择的字段(dataIndex:'codeChecklistItemStatus')被更新为整数。 Upon saving, the field codeChecklistItemStatus gets changed from a String description to the new id value, and the field I want to change codeChecklistItemStatusId still has the original id value.
保存后,字段codeChecklistItemStatus从字符串描述更改为新的id值,而我要更改codeChecklistItemStatusId的字段仍具有原始ID值。
All the examples I've found online have a string value being saved instead of an id value. 我在网上找到的所有示例都保存了一个字符串值,而不是一个id值。 Is there any way to change the codeChecklistItemStatusId field instead of codeChecklistItemStatus?
有什么方法可以更改codeChecklistItemStatusId字段而不是codeChecklistItemStatus吗?
I've put dataIndex: 'codeChecklistItemStatusId' in my grid and the grid then displays numbers to the user instead of a description. 我将dataIndex:'codeChecklistItemStatusId'放入网格中,然后网格向用户显示数字而不是描述。 However, when saving the correct field codeChecklistItemStatusId is updated correctly.
但是,保存正确的字段代码时CheckListItemStatusId会正确更新。
The ChecklistItem store: ChecklistItem存储:
Ext.define('gui.store.IspIntakeChecklistItem',
{
extend: 'Ext.data.Store',
model: 'gui.model.IspIntakeChecklistItem',
root: 'data',
proxy:
{
type: 'ajax',
api:
{
read: 'ispIntakeChecklistItem/search',
update: 'ispIntakeChecklistItem/quickEdit'
},
actionMethods:
{
read: 'POST'
},
reader:
{
type: 'json',
rootProperty: 'data'
},
writer:
{
type: 'json',
allowSingle: false,
writeAllFields: true
}
}
});
The CheckListItem model: CheckListItem模型:
Ext.define('gui.model.IspIntakeChecklistItem',
{
extend: 'Ext.data.Model',
fields: [
{
name: 'id'
},
{
name: 'codeChecklistItemStatusId'
},
{
name: 'codeChecklistItemStatus'
},
{
name: 'followUpDate'
}
]
});
The store of the combobox: 组合框的存储:
Ext.define('gui.store.maint.CodeChecklistItemStatus',
{
extend: 'Ext.data.Store',
remoteSort: true,
pageSize: gui.data.Constants.MAX_CODE_RESULTS_IN_GRID,
model: 'gui.model.maint.CodeChecklistItemStatus',
root: 'data',
autoLoad: true,
proxy:
{
type: 'ajax',
api:
{
read: 'codeChecklistItemStatus/search',
update: 'codeChecklistItemStatus/updateSortOrder'
},
actionMethods:
{
read: 'POST'
},
reader:
{
type: 'json',
rootProperty: 'data'
}
}
});
The model of the combobox: 组合框的模型:
Ext.define('gui.model.maint.CodeChecklistItem',
{
extend: 'Ext.data.Model',
fields: [
{
name: 'id'
},
{
name: 'activeFlag'
},
{
name: 'description'
},
{
name: 'sortOrder'
},
{
name: 'createDate'
},
{
name: 'createUser'
},
{
name: 'lastUpdDate'
},
{
name: 'lastUpdUser'
}
]
});
Here are a few of the fields in the grid that has CellEditing enabled: 以下是网格中启用了CellEditing的一些字段:
{
text: 'Checklist Item Status',
itemId: 'codeChecklistItemStatusGridFld',
dataIndex: 'codeChecklistItemStatus',
width: 200,
editor: {
xtype: 'combobox',
queryMode: 'local',
valueField: 'id',
displayField: 'description',
typeAhead: true,
forceSelection: true,
store: 'maint.CodeChecklistItemStatus',
allowBlank: false
},
tdCls: 'editableCell'
},
{
text: 'Follow Up Date',
dataIndex: 'followUpDate',
width: 150,
editor: {
xtype: 'datefield'
},
tdCls: 'editableCell'
}
My controller function: 我的控制器功能:
quickEditChecklistItem: function(editor, e, eOpts) {
if (e.originalValue !== e.value) {
debugger;
var rec = e.record;
var store = this.getIspIntakeChecklistItemStore();
//store.add(rec);
store.sync({
scope: this,
success: function(batch, options) {
Ext.create('gui.widget.Notify').success('Checklist Item saved successfully');
},
failure: function(batch, options) {
Ext.create('gui.widget.Notify').failure('failure');
}
});
}
}
A colleague of mine figured out how to do this. 我的一位同事想出了办法。 On the grid all I need to define is the dataIndex for the combobox column:
在网格上,我需要定义的只是combobox列的dataIndex:
{
xtype: 'editableComboboxGridColumn',
dataIndex: 'codeChecklistItemStatusId'
},
He created a reusable xtype that will handle all the messy code: 他创建了一个可重用的xtype,它将处理所有混乱的代码:
Ext.define('gui.widget.EditableComboboxGridColumn', {
extend: 'Ext.grid.column.Column',
xtype: 'editableComboboxGridColumn',
width: 200,
tdCls: 'editableCell',
//Required property: dataIndex
initComponent: function()
{
var nameCamel = Utilities.toCamelCase(this.dataIndex);
nameCamel = Utilities.removeId(nameCamel);
if (this.text == ' ')
this.text = Utilities.fieldNameToLabel(this.dataIndex);
if (!this.itemId)
this.itemId = Utilities.removeId(this.dataIndex) + "GridFld";
if (!this.store)
this.store = 'maint.' + nameCamel;
if (!this.editor)
{
this.editor =
{
xtype: 'combobox',
queryMode: 'local',
valueField: (this.valueField ? this.valueField : 'id'),
displayField: (this.displayField ? this.displayField : 'description'),
typeAhead: true,
forceSelection: true,
store: this.store,
allowBlank: false
}
}
if (!this.renderer)
{
this.renderer = function (value, metaData, record)
{
var editor = metaData.column.getEditor(record);
var storeRecord = editor.store.getById(value);
if(storeRecord)
return storeRecord.data[editor.displayField];
else
return null;
}
}
this.callParent(arguments);
}
});
Other code in Utilities.js: Utilities.js中的其他代码:
Ext.define('gui.Utilities',
{
alternateClassName: 'Utilities',
singleton: true,
fieldNameToLabel: function(name)
{
var nameProper = '';
for (var i = 0; i < name.length; i++) {
var character = name.substr(i, 1);
if (character.toUpperCase() == character)
nameProper += ' ';
if (nameProper.length == 0)
nameProper += character.toUpperCase();
else
nameProper += character;
}
if (nameProper.indexOf('Code ') == 0)
nameProper = nameProper.substring(5);
if (nameProper.length == nameProper.indexOf(' Id') + 3)
nameProper = nameProper.substring(0, nameProper.length - 3);
var regex = / Flag$/
if (regex.test(nameProper))
nameProper = nameProper.replace(regex, '');
if (nameProper.indexOf(' Upd ') > -1)
nameProper = nameProper.replace(' Upd ', ' Update ');
return nameProper;
},
toCamelCase: function(name)
{
return name.substring(0, 1).toUpperCase() + name.substring(1);
},
removeId: function(name)
{
var regex = /\s?Id$/;
if (regex.test(name))
name = name.replace(regex, '');
return name;
}
});
We originally started with this code before developing the generic xtype: 在开发通用xtype之前,我们最初是从以下代码开始的:
renderer : function (value, metaData, record) {
var editor = metaData.column.getEditor(record);
var storeRecord = editor.store.getById(value);
if(storeRecord)
return storeRecord.data[editor.displayField];
else
return null;
}
