我有以下Laravel Fluent查询从博客返回分页结果。我试图在输出中包括来自Posts表的id列，但视图中的$post->id在分页结果中返回该帖子的数字键。例如，如果这是第三篇文章，$post->id将返回3，即使表中的ID可能是24。
下面是查询-
$posts = DB::table('posts')
->join('blog_categories', 'blog_categories.id', '=', 'posts.blog_category_id')
->order_by('created_at', 'desc')
->paginate(10);
我如何检索id列像postID一样，而不破坏分页?
谢谢!
posts和blog_categories都有自己的id字段，所以它只是默认为第一个记录，通常只是"1"。我会考虑使用Eloquent ORM来解决这个问题。
http://laravel.com/docs/database/eloquent
然后你可以这样做:
$posts = Post::order_by('created_at', 'desc')->paginate(10);
And from the view:
@foreach($posts as $post)
{{ $post->id }}
{{ $post->blog_cat->.... }}
@endforeach
我不知道你的项目的具体要求，但这应该会让你朝着正确的方向前进。
工作版本:
数据库迁移/ // Blog Categories
Schema::create('categories', function($table) {
$table->engine = 'InnoDB';
$table->increments('id');
$table->string('name', 255);
$table->timestamps();
});
// Posts
Schema::create('posts', function($table) {
$table->engine = 'InnoDB';
$table->increments('id');
$table->integer('category_id')->unsigned();
$table->string('title', 255);
$table->text('body');
$table->timestamps();
$table->foreign('category_id')->references('id')->on('categories');
});
// Fake Data
$category = new Category;
$category->name = 'Category 1';
$category->save();
$category = new Category;
$category->name = 'Category 2';
$category->save();
$post = new Post;
$post->title = 'Blog Post 1';
$post->body = 'Lorem Ipsum';
$post->category_id = 2;
$post->save();
$post = new Post;
$post->title = 'Blog Post 2';
$post->body = 'Lorem Ipsum';
$post->category_id = 1;
$post->save();
Post模型
class Post extends Eloquent {
public function Category()
{
return $this->belongs_to('Category','category_id');
}
}
class Category extends Eloquent {
}
foreach (Post::with('Category')->order_by('created_at', 'desc')->take(10)->get() as $post)
{
echo $post->title."<br/>";
echo $post->body."<br/>";
echo $post->category->name."<br/>";
echo "<br/>'n'n";
}
