QLSTATE [22007]：无效的日期时间格式：1366 不正确的 integer 值 laravel

Question

I cannot store the company that my client belongs to. The company is a foreign key and when I click register customer I get an error:

SQLSTATE[22007]: Invalid datetime format: 1366 Incorrect integer value: 'Tim' for column customerlist . customers . company at row 1 (SQL: insert into customers ( company , name , document , phone , email , updated_at , created_at ) values (Tim, Felix Botta, 04919407939, +55.41984081085,felix.botta@gmail.com, 2021-02-14 20:55:15, 2021-02-14 20:55:15))

CustomerController

class CustomersController extends Controller
{
public function index(){
    $customers = Customer::get();
    return view('customers.list', ['customers' => $customers]);
}

public function new(){
    $companies = Company::orderBy('id', 'desc')->get();
    return view('customers.form', ['companies' => $companies]);
}

public function add( Request $request ){

    $customers = new Customer;
    $customers = $customers->create( $request->all() );
    
    return Redirect::to('/customers');
}

public function edit( $id ){
    $customers = Customer::findOrFail( $id );
    return view('customers.form', ['customers' => $customers]);
}

public function update( $id, Request $request ){
    $customers = Customer::findOrFail( $id );
    $customers->update( $request->all() );
    return Redirect::to('/customers');
}

public function delete( $id ){
    $customers = Customer::findOrFail( $id );
    $customers->delete();
    return Redirect::to('/customers');
}}

Answer 1

According to the migration the company column is integer and foreign key that points to companies table and according to error you are passing string value Tim for company column. So in blade view change

<option value="{{ $company->name }}">{{ $company->name }}</option>

to

<option value="{{ $company->id }}">{{ $company->name }}</option>
