LARAVEL 行克隆获得选择 SQL 错误

问题描述

嗨，我已经被困在这里好几天了， 我正在尝试使用复制方法从我的数据库克隆一行。但我收到错误

这是我的代码：

 foreach($e_inserts as $e_data){
$enrollment = \App\Enrollment::find($e_data['enrollment_id']); //CLONE ENROLLMENTS
                                $new_enrollment = $enrollment->replicate();
                                $new_enrollment->term_id = $input['term_to'];
                                $new_enrollment->enrollment_status = 'waiving';
                                $new_enrollment->save();
}

我收到一个插入的选择错误

1sqlSTATE[21000]: Cardinality violation: 1242 Subquery returns more than 1 row (sql: insert into `enrollments` (`user_id`,`participation_id`,`term_id`,`email`,`ssn`,`student_id`,`effective_date`,`termination_date`,`last_name`,`first_name`,`middle_initial`,`dob`,`gender_code`,`identify_as`,`academic_level`,`enrollee_category`,`address`,`address2`,`city`,`state`,`zip`,`zip_reserve`,`phone`,`alt_phone`,`notification_phone`,`emergency_contact_first_name`,`emergency_contact_last_name`,`emergency_contact_relationship`,`emergency_contact_phone`,`emergency_contact_email`,`beneficiary_contact_first_name`,`beneficiary_contact_last_name`,`beneficiary_contact_relationship`,`beneficiary_contact_phone`,`beneficiary_contact_email`,`academic_status`,`opt_status`,`enrollment_status`,`dependents`,`spouse`,`agree`,`no_us_address`,`country_of_study`,`home_country`,`ead_start_date`,`ead_end_date`,`action_taken`,`completed`,`status_updated_at`,`deleted_at`,`carrier_sent`,`carrier_member_id`,`custom_history`,`locked`,`updated_at`,`created_at`) values (59536,728,2777,[e-mail],test_waived_2,?,Email,Match,2000-01-01,M,UNDG,DOM,6162 Rotary Way,Joshua Tree,CO,92252,none,FT,out,waiving,1,2021-07-25 11:57:35,2021-07-27 03:20:09,2021-07-27 06:30:30,2021-07-27 06:30:30))" 

解决方法

试试这个

$new_enrollment = $enrollment->replicate()->fill([
   'term_id' = $input['term_to'];
   'enrollment_status' = 'waiving';
]);

$new_enrollment->save();
