我对laravel相当陌生，尝试在数据库中输入值时遇到此问题。同样的事情对于患者的表和表格有效，但不适用于医生。如果有人可以指出我哪里出了问题，那将是不胜感激的
表格
{
public function up()
{
Schema::create('doctors', function (Blueprint $table) {
$table->increments('id');
$table->integer('uid')->unique();
$table->string('first_name');
$table->string('last_name');
$table->string('phone');
$table->string('username')->unique();
$table->string('email');
$table->string('password');
$table->longText('address')->nullable();
$table->longText('education')->nullable();
$table->longText('specialist')->nullable();
$table->date('dob');
$table->string('blood_group',5);
$table->enum('sex',['M','F','O']);
$table->string('nid_file')->nullable();
$table->string('cv_file')->nullable();
$table->string('picture')->nullable();
$table->boolean('status')->default(1);
$table->unsignedInteger('designation_id');
$table->unsignedInteger('department_id');
$table->rememberToken();
$table->timestamps();
$table->foreign('designation_id')->references('id')->on('designations')->onDelete('cascade');
$table->foreign('department_id')->references('id')->on('departments')->onDelete('cascade');
});
}
/**

*/
public function down()
{
Schema::dropIfExists('doctors');
}
}
我要通过其输入值的视图

更新：感谢所有经历过这一重要帖子并回答的人。
答案 0 :(得分：1)
您收到此错误，因为在迁移中列 first_name 不可为空。这意味着您必须为此列提供一个值。
在您的表单中将这些字段设为必填是一种很好的做法，因此用户必须填写这些字段。另外，您可以利用服务器端validation来验证发布的请求。
答案 1 :(得分：1)
$doctor->first_name = $request->input('fname');
应使用与输入名称相同的形式访问请求属性，因此为“ first_name”
$doctor->first_name = $request->input('first_name');
这也适用于：
$doctor->last_name = $request->input('lname');
应该是：
$doctor->last_name = $request->input('last_name');
答案 2 :(得分：0)
异常Illuminate \ Database \ QueryException (23000) SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'first_name' cannot be null
本身表示错误，列first_name不能为空。您必须将列first_name设置为可空，或者必须插入数据。
检查表单，是否正确提交数据，然后从插入数据的位置检查控制器。
在保存数据之前在控制器中使用Validator。这是示例，
$validator = Validator::make($request->input() , [
'first_name' => 'required',
'last_name' => 'required',
........
])
然后您可以按照验证者的身份检查您的请求
if($validation->fails()){
//Validation failed
}else{
//Success, process the request data
}
答案 3 :(得分：0)
如果您在表单中看到input last_name的名字是last_name
在您的controller中，您正在寻找错误的$request->input('lname');
要么更改此
<input type="text" class="form-control" id="last_name" name="last_name" placeholder="Last Name">
到
<input type="text" class="form-control" id="last_name" name="lname" placeholder="Last Name">
或者在您的控制器中，您可以代替$request->input('lname');来执行此操作，而只能使用$request->input('last_name');，firstname也会如此
谢谢
答案 4 :(得分：0)
$ request-> input（'first_name'）;或$ request-> first_name;
