[英]column exist but when migration it returns SQLSTATE[42000]: Syntax error or access violation: 1072 Key column doesn't exist in table
[英]SQLSTATE[42000]: Syntax error or access violation: 1072 Key column 'proform_id' doesn't exist in table
在 php artisan migrate:fresh 之后我得到错误:
SQLSTATE[42000]:语法错误或访问冲突:1072 表中不存在键列“proform_id”(SQL:alter table proforms
add constraint proforms_proform_id_foreign
外键( proform_id
)在删除级联时引用proforms
( id
))
这是生成错误的迁移:2020_08_08_093303_create_dynamic_field.php

这是与之相关的迁移:2020_07_29_101958_proforms.php
<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class Proforms extends Migration

/**

public function up()
{
Schema::create('proforms', function (Blueprint $table) {
$table->increments('id');
$table->integer('proformnumber')->nullable();
$table->date('proformdate')->nullable();
$table->date('selldate')->nullable();
$table->integer('user_id')->unsigned()->nullable();
$table->integer('form_id')->unsigned()->nullable();
$table->integer('currency_id')->unsigned()->nullable();
$table->string('paymentmethod')->nullable();

});
Schema::table('proforms', function (Blueprint $table){
$table->foreign('user_id')
->references('id')
->on('users')

->references('id')
->on('forms')
->onDelete('cascade');
$table->foreign('currency_id')
->references('id')

});
这对我来说很奇怪:
Schema::table('proforms', function (Blueprint $table) {
$table->foreign('proform_id')
->references('id')
->on('proforms')
->onDelete('cascade');
});
看起来您正在尝试添加一个引用它自己的表的外键。
proforms
表上没有proform_id
。 该语句需要在dynamic_fields
表上运行。
Schema::table('dynamic_fields', function (Blueprint $table) {
$table->foreign('proform_id')
->references('id')
->on('proforms')
->onDelete('cascade');
});
