Laravel über Fremdschlüssel falsch

Question

gebildet Hey Jungs, die ich zu viele Sachen ausprobiert und einige Blogs lesen oder Diskussion, die ich repariere nicht mein Problem, das ich bin neu in Laravel dieses Projekt für meine Universität Lektion ... habe ich Fehler, wenn ich will Datenbank diese Fehler wie

[Illuminate\Database\QueryException]           
SQLSTATE[HY000]: General error: 1005 Can't create table `moviestore`.`#sql- 
13df8_27` (errno: 150 "Foreign key constraint is incorrectly formed") (SQL: 
alter table `orders` add constraint `orders_address_id_foreign` foreign ke 
y (`address_id`) references `addresses` (`id`)) 

und dies ist mein Codes

public function up() 
{ 
    Schema::create('orders', function (Blueprint $table) { 
     $table->engine = 'InnoDB'; 
     $table->increments('id'); 
     $table->dateTime('OrderDate'); 
     $table->integer('TotalCount'); 
     $table->decimal('TotalPrice',20,2); 
     $table->integer('user_id')->unsigned(); 
     $table->integer('address_id')->unsigned(); 
     $table->timestamps(); 

     $table->foreign('user_id')->references('id')->on('users'); 
     $table->foreign('address_id')->references('id')->on('addresses'); 
    }); 

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

/** 
* Reverse the migrations. 
* 
* @return void 
*/ 
public function down() 
{ 
    DB::statement('SET FOREIGN_KEY_CHECKS=0'); 
    Schema::dropIfExists('orders'); 
    DB::statement('SET FOREIGN_KEY_CHECKS=1'); 
} 

Adressen Tabellencode

public function up() 
{ 
    Schema::create('addresses', function (Blueprint $table) { 
     $table->engine = 'InnoDB'; 
     $table->increments('id'); 
     $table->string('FullAddress'); 
     $table->string('AddressType'); 
     $table->string('PhoneNumber'); 
     $table->integer('user_id')->unsigned(); 
     $table->timestamps(); 

     $table->foreign('user_id')->references('id')->on('users'); 
    }); 
} 

/**

* 
* @return void 
*/ 
public function down() 
{ 
    DB::statement('SET FOREIGN_KEY_CHECKS=0'); 
    Schema::dropIfExists('addresses'); 
    DB::statement('SET FOREIGN_KEY_CHECKS=1'); 
} 

erstellen

Es gibt keine Beziehung zwischen den einzelnen Tabellen, wenn ich Tabellen

wandern Ich glaube, Sie benötigen eine Migrationsdatei zu aktualisieren, wie:

Zuerst Addresses Migration laufen, weil Addresses.id Fremdschlüssel orders.address_id

ist Adressen Tabellencode

public function up() 
{ 
    Schema::create('addresses', function (Blueprint $table) { 
     $table->engine = 'InnoDB'; 
     $table->increments('id'); 
     $table->string('FullAddress'); 
     $table->string('AddressType'); 
     $table->string('PhoneNumber'); 
     $table->integer('user_id')->unsigned(); 
     $table->timestamps(); 

     $table->foreign('user_id')->references('id')->on('users')->onDelete('cascade'); 
    }); 
} 

/** 
* Reverse the migrations. 
* 
* @return void 
*/ 
public function down() 
{ 
    DB::statement('SET FOREIGN_KEY_CHECKS=0'); 
    Schema::dropIfExists('addresses'); 
    DB::statement('SET FOREIGN_KEY_CHECKS=1'); 
} 

Tabelle Orders

public function up() 
{ 
    Schema::create('orders', function (Blueprint $table) { 
     $table->engine = 'InnoDB'; 
     $table->increments('id'); 
     $table->dateTime('OrderDate'); 
     $table->integer('TotalCount'); 
     $table->decimal('TotalPrice',20,2); 
     $table->integer('user_id')->unsigned(); 
     $table->integer('address_id')->unsigned(); 
     $table->timestamps(); 

     $table->foreign('user_id')->references('id')->on('users')->onDelete('cascade'); 
     $table->foreign('address_id')->references('id')->on('addresses')->onDelete('cascade'); 
    }); 


} 

/** 
* Reverse the migrations. 
* 
* @return void 
*/ 
public function down() 
{ 
    DB::statement('SET FOREIGN_KEY_CHECKS=0'); 
    Schema::dropIfExists('orders'); 
    DB::statement('SET FOREIGN_KEY_CHECKS=1'); 
}
