将数据发送到API并将其检索到网格
在我的项目中，我在前端使用extjs。 yii2在后端。我创建了一个表单来从数据库中检索选定的数据。
如您所见，我有两个日期字段和一个下拉列表。我有一组复选框。这是我的数据库表的屏幕截图。
我应该使用复选框选择我想要的数据，然后从＆＃39;之间的数据库中获取数据。到＆＃39;到＆＃39;日期。当我单击RUN按钮时，那些选定的数据应该加载到下面的网格中。当我单击下载按钮时，应将这些选定的数据下载到csv文件中。但是当我单击RUN按钮时，它会发送两次相同的API调用。并且一个API正确地获取数据，而另一个API发送并且错误地说“未定义的索引：来自＆＃39;”。这是我视图中的代码。

我将这些数据发送到商店文件。这是商店文件代码。
extend: 'Ext.data.Store',

autoLoad: false,
pageSize: Configs.grid.pageSize,
saveRecord: function(data,fnCallBack) {
var me = this;
//var data = this.data;
//autoLoad: true,
//console.log(data);
Ext.getBody().mask('Please wait...');
Ext.Ajax.request({

params: data,
callback: function(opts, success, res) {
Ext.getBody().unmask();
try {
if(success) {
var response = App.decodeHttpResp(res.responseText);
if(response.success) {
Ext.Msg.show({

title: 'Reports',
msg: 'Report saved successfully'
});
} else {
throw response.error;
}
me.load();
} else {
throw 'Unknown Reason';
}
} catch (ex) {
Ext.Msg.show({

buttons: Ext.Msg.OK,
title: 'Report',
msg: 'Failed to save data<br />' +
'Reason: ' + ex
});
}
}

}
这是我的前端模特。

noCache: false,
actionMethods: {'read': 'POST'},
api: {

// update: utils.createUrl('api', 'user-update'),
// destroy: utils.createUrl('api', 'user-delete')
},
reader: {

root: 'data'
},
listeners: {
exception: function(proxy, response, operation) {
App.showHttpError('Reports', response);
//console.log(this.fields);
}
}
}
使用这些文件我将数据发送到控制器。这就是定义我的API的地方。
这是我的控制器功能。
public function actionReportRead(){
$post = Yii::$app->request->post();
$time = 0;
$_vals = (new Order())->readReports(
@$post['start'],
@$post['limit'],
$post['from'],
$post['to'],
@$post['rb1'],
@$post['rb2'],
@$post['rb3'],
@$post['rb5'],
@$post['rb4'],
@$time,
@$post['rb6'],
@$post['rb7']
);
$this->setOutputData($_vals);
$this->setOutputStatus(true);
}
这就是模型。
public function readReports($start, $limit,$from,$to, $rb1, $rb2, $rb3, $rb5, $rb4, $time, $rb6, $rb7 )
{
if (!$start) { $start = 0; };
if (!$limit) { $limit = Config::PAGE_SIZE; };
//$q = (new ActiveQuery(self::className()));
$q = self::find();
//$q->where(['between', 'submitted_time', $from, $to ]);
$q->alias('T')->andWhere(['BETWEEN', 'T.submitted_time', $from, $to ]);
$q->limit($limit);
$q->offset($start);
$q->orderBy(['T.order_id' => SORT_ASC]);
$data = [];
$action = null;
foreach ($q->all() as $_o) {
if($_o->status == 2){
$action = 'Data Entry Verified';
$time = $_o->timeDataEntry;
}else if($_o->status == 3){
$action = 'QC Accepted';
$time = $_o->timeQcPass;
}else if($_o->status == 4){
$action = 'Accepted';
$time = $_o->timeVerify;
}else if($_o->status == 1){
$action = 'Verification Pending';
$time = $_o->timeQcReject;
}else if($_o->status == 0){
$action = 'Rejected';
$time = $_o->timeQcReject;
}
$userlist='SELECT name FROM Company WHERE id = '.$_o->company_id;
$rsuserlist = Yii::$app->db->createCommand($userlist)->query();
$row = $rsuserlist->read();
$data[] = (object) array(
'date' =>$_o->submitted_time,
'rb1' =>$_o->order_id,
'rb2' =>$_o->conn,
'rb3' =>$_o->status,
'rb5' =>$_o->conn_type,
'rb4' =>$action,
'time' =>$time,
'rb6' =>$_o->channel,
'rb7' =>$row['name']
);
}
$json=Json::encode($data);
$this->logger->actLog($json);
return $data;
}
我发现后端很好。但我不太确定。我是extjs的新手。所以，我尝试了很多方法，但没有任何效果。我之前提到过，数据没有被加载到网格，API会向我发送错误。请帮我解决这个问题。我该怎么做。
1 个答案:
答案 0 :(得分：0)
我找到了答案，我正在回答我自己的问题。
这里，一个API可以正确获取所有数据。其他人没有得到'从'和'到'的价值观。所以我使用了以下代码。
me.store.getProxy().extraParams = {
from: vals.from,
to: vals.to
};
使用这个我可以将所有参数发送到其他API并消除该问题。现在数据被提取到网格没有问题。
