軟刪除：

<?php
namespace?app\index\model;
use?think\Model;
use?traits\model\SoftDelete;
class?User?extends?Model{
????use?SoftDelete;
????#autowritetimestamp表示創(chuàng)建與更新的時間戳都被打開
????protected?$autoWriteTimestamp?=?true;
????#刪除數(shù)據(jù)的時候刪除時間戳默認(rèn)寫入字段delete_time中，當(dāng)要自定義時：
//????protected?$deleteTime?=?'自定義刪除時間字段名';
}

然后在控制器里面執(zhí)行操作

<?php
namespace?app\index\controller;
use?think\Controller;
use?app\index\model\User;
class?Index?extends?Controller
{
????public?function?index(){
//????????$res?=?User::destroy(4);//被軟刪除
//????????$res?=?User::get(2);//返回NULL

????????#查詢包含已刪除的數(shù)據(jù)
????????//$res?=?User::withTrashed(true)->find(2);

????????#查詢僅包含已刪除的數(shù)據(jù)
????????$res?=?User::onlyTrashed()->select();
????????foreach?($res?as?$val){
????????????dump($val);
????????}
????????#若要恢復(fù)被軟刪除的數(shù)據(jù)，直接用update方式將delete_time的值設(shè)置為NULL即可

????????#當(dāng)開啟軟刪除后要想真正徹底刪除數(shù)據(jù),在destroy的第二個參數(shù)后面?zhèn)魅胍粋€true值
????????$res?=?User::destroy(1,true);

????????#通過get方式進行軟刪除/刪除
????????$res?=?User::get(3);//如果此處數(shù)據(jù)已經(jīng)被軟刪除則獲取到的為NULL，后面的操作無效
????????$user->delete();//軟刪除
????????$res?=?$user->delete(true);//刪除
????}
}

模型時間戳：

<?php
namespace?app\index\model;
use?think\Model;

class?User?extends?Model{
????#autowritetimestamp表示創(chuàng)建與更新的時間戳都被打開
????protected?$autoWriteTimestamp?=?true;
//????#createtime為false表示創(chuàng)建的時間戳被關(guān)閉
//????protected?$createTime?=?false;
//????#updatetime為true表示更新時間戳被打開
//????protected?$updateTime?=?true;
//????#創(chuàng)建數(shù)據(jù)的時候創(chuàng)建時間戳默認(rèn)寫入字段create_time中，當(dāng)要自定義時：
//????protected?$createTime?=?'自定義創(chuàng)建時間字段名';
//????#更新數(shù)據(jù)的時候更新時間戳默認(rèn)寫入字段update_time中，當(dāng)要自定義時：
//????protected?$updateTime?=?'自定義更新時間字段名';
}

模型修改器與自動完成

<?php
namespace?app\index\model;
use?think\Model;
class?User?extends?Model{
????#get+字段名+Attr
????public?function?getGenderAttr($val){
????????switch?($val){
????????????case?"1";
????????????????return?'男';
?????????????????break;
????????????case?"2";
?????????????????return?'女';
??????????????????break;
????????????default;
?????????????????return?'未知';
?????????????????break;
????????}
????}
????#模型修改
//????public?function?setPasswordAttr($val,$data){
//????????return?$val.$data['email'];
//????}

????#無論對數(shù)據(jù)庫執(zhí)行插入&更新操作，總是在數(shù)據(jù)中加上time字段相應(yīng)的值
????protected?$auto?=?[
??????'time'//字段名
????];
????public?function?setTimeAttr(){
????????return?time();//字段對應(yīng)的值
????}

????#insert/update對數(shù)據(jù)庫執(zhí)行插入/更新操作時，在數(shù)據(jù)字段中加入對應(yīng)的值
????protected?$insert?=?[
????????'insert'//字段名
????];
????public?function?setInsertAttr(){
????????return?time();
????}
}

模型獲取器：

首先設(shè)置User模型：

<?php
namespace?app\index\model;
use?think\Model;
class?User?extends?Model{
????#get+字段名+Attr
????public?function?getGenderAttr($val){
????????switch?($val){
????????????case?"1";
????????????????return?'男';
?????????????????break;
????????????case?"2";
?????????????????return?'女';
??????????????????break;
????????????default;
?????????????????return?'未知';
?????????????????break;
????????}
????}
}

然后在index控制器中操作：

<?php
namespace?app\index\controller;
use?think\Controller;
use?app\index\model\User;
class?Index?extends?Controller
{
????public?function?index(){
????????$res?=?User::get(1);
????????dump($res->gender);//獲取性別單欄數(shù)據(jù)
????????dump($res->toArray());//以數(shù)組形式獲取整條數(shù)據(jù)，性別顯示為男/女/未知
????????dump($res->getData());//以原始形式獲取整條數(shù)據(jù)，性別顯示為1/2/其他
????}
}
