Laravel Model函数之间的“创建"区别是什么?和“插入"? [英] What's difference between Laravel Model functions "create" and "insert"?

问题描述

Laravel模型允许使用两个函数将值插入数据库表.他们是

Laravel Model allows two functions for inserting the values to the database table. They are

创建: User::create(['id'=>1,'name'=>'stack']);

插入: User::insert(['id'=>2,'name'=>'overflow']);

我发现他们执行类似的操作.他们之间有什么区别?

I found they perform similar operations. What's difference between them?

推荐答案

insert():

如果使用insert()方法，则无法默认使用created_at和Updated_at数据库列 将为空

If you using insert() method you can't default created_at and updated_at database column it will be null

DefaultUser::insert(['username'    =>  $request->username, 'city'  =>  $request->city, 'profile_image' =>  $request->profile_image]);

---

create(): 当我们使用创建方法时，必须在可填充字段

---

create() : when we use create method you must define this model in fillable fields

添加模型

 protected $fillable = ['username','city', 'profile_image'];

添加您的控制器

DefaultUser::create(['username'    =>  $request->username, 'city'  =>  $request->city, 'profile_image' =>  $request->profile_image]);

然后我们可以使用create方法而不会出现** mass分配错误** 基本上在这里，表定义的字段在您的模型中受到保护

then we can use create method without **mass assignment error ** basically here , table defined fields are protected in your model

，您应该定义要批量分配的模型属性.您可以使用模型上的$ fillable属性来完成此操作
