如何创建seeder类及其存储位置
我正在学习本教程,现在我们正在“为数据库播种关系”
这是我的DatabaseSeeder.php
// app/database/seeds/DatabaseSeeder.php
<?php
use App\Bear;
use App\Tree;
use App\Fish;
use App\Picnic;
use Illuminate\Database\Seeder;
class DatabaseSeeder extends Seeder
{
/**
* Run the database seeds.
*
* @return void
*/
public function run()
{
Eloquent::unguard();
// call our class and run our seeds
$this->call('BearAppSeeder');
$this->command->info('Bear app seeds finished.'); // show information in the command line after everything is run
}
}
// our own seeder class
// usually this would be its own file
class BearAppSeeder extends Seeder
{
public function run()
{
// clear our database ------------------------------------------
DB::table('bears')->delete();
DB::table('fish')->delete();
DB::table('picnics')->delete();
DB::table('trees')->delete();
DB::table('bears_picnics')->delete();
// seed our bears table -----------------------
// we'll create three different bears
// bear 1 is named Lawly. She is extremely dangerous. Especially when hungry.
$bearLawly = Bear::create(array(
'name' => 'Lawly',
'type' => 'Grizzly',
'danger_level' => 8
));
// bear 2 is named Cerms. He has a loud growl but is pretty much harmless.
$bearCerms = Bear::create(array(
'name' => 'Cerms',
'type' => 'Black',
'danger_level' => 4
));
// bear 3 is named Adobot. He is a polar bear. He drinks vodka.
$bearAdobot = Bear::create(array(
'name' => 'Adobot',
'type' => 'Polar',
'danger_level' => 3
));
$this->command->info('The bears are alive!');
// seed our fish table ------------------------
// our fish wont have names... because theyre going to be eaten
// we will use the variables we used to create the bears to get their id
Fish::create(array(
'weight' => 5,
'bear_id' => $bearLawly->id
));
Fish::create(array(
'weight' => 12,
'bear_id' => $bearCerms->id
));
Fish::create(array(
'weight' => 4,
'bear_id' => $bearAdobot->id
));
$this->command->info('They are eating fish!');
// seed our trees table ---------------------
Tree::create(array(
'type' => 'Redwood',
'age' => 500,
'bear_id' => $bearLawly->id
));
Tree::create(array(
'type' => 'Oak',
'age' => 400,
'bear_id' => $bearLawly->id
));
$this->command->info('Climb bears! Be free!');
// seed our picnics table ---------------------
// we will create one picnic and apply all bears to this one picnic
$picnicYellowstone = Picnic::create(array(
'name' => 'Yellowstone',
'taste_level' => 6
));
$picnicGrandCanyon = Picnic::create(array(
'name' => 'Grand Canyon',
'taste_level' => 5
));
// link our bears to picnics ---------------------
// for our purposes we'll just add all bears to both picnics for our many to many relationship
$bearLawly->picnics()->attach($picnicYellowstone->id);
$bearLawly->picnics()->attach($picnicGrandCanyon->id);
$bearCerms->picnics()->attach($picnicYellowstone->id);
$bearCerms->picnics()->attach($picnicGrandCanyon->id);
$bearAdobot->picnics()->attach($picnicYellowstone->id);
$bearAdobot->picnics()->attach($picnicGrandCanyon->id);
$this->command->info('They are terrorizing picnics!');
}

我已经尝试了这里找到的所有答案,还有
composer dump autoload
,但没有乐趣。您需要确保导入您的类扩展的LightingSeeder
类
使用App\Bear;
使用App\Tree;
使用App\Fish;
使用应用程序\野餐;
使用照明\数据库\播种机;
类DatabaseSeeder扩展了Seeder

在你的班级顶端好的,谢谢。我这样做了,现在我得到了一个新的错误
class'Bear'not found
谢谢,现在我得到了这个class'App\Bear'not found
更新,我会得到同样的class'App\Bear'not found
错误。这一行似乎是一个致命的错误$bearLawly=Bear::create(数组(
我在上面的问题中更新了我的播种机代码。问题可能是我的数据库表名为“bears”而不是“bear”?或者可能是在我的公共函数run()
,而不是DB::table('bears')->delete();
我需要数据库名bears::table('bears')->delete();
?对照use
指令检查名称空间中CAP的一致性。请参阅以了解可能存在的相同问题。
// app/models/seeder.php
<?php
class Seeder extends Seeder
{
protected $fillable = [];
protected $table = 'bear';
