Laravel 迁移时外键不起作用
外键不工作 这是我的迁移文件Laravel 迁移时外键不起作用,laravel,laravel-5,Laravel,Laravel 5,外键不工作 这是我的迁移文件 Schema::create('course_prospect', function (Blueprint $table) { $table->bigIncrements('id'); $table->integer('prospect_id')->length(11)->unsigned(); $table->foreign('prospect_id')->references('id')-

我犯了这个错误
Illuminate\Database\QueryException : SQLSTATE[HY000]: General error:
1005 Can't create table `customerinquirydb`.`#sql-104c_e9` (errno: 150
"Foreign key constraint is incorrectly formed") (SQL: alter table
`course_prospect` add constraint `course_prospect_prospect_id_foreign`
foreign key (`prospect_id`) references `prospect` (`id`))
在Laravel中迁移具有外键的表时。必须首先创建外键所在的表(必须存在)!因此,请确保情况确实如此。我认为这一行中可能重复的
id
应替换为prospect\u id
$table->foreign('prospect\u id')->引用('id')->on('prospect')代码>您是否也可以添加潜在客户和课程表?
