这是我的控制器代码,用于获取两个对象。在我使用的每个对象的末尾 - > get();显示错误的未定义变量。但是当我使用 - > first();它工作正常但只显示第一条记录。但我需要整个记录。
public function ratingdata()
{
$pacra['pacra'] = DB::table('og_ratings AS p')
->select('p.client_id as Id','p.ppl_date as Ppl','p.notification_date as Notification ',
'p.dissemination_date as Dissemination', 'p.rating_type_id as ratingTypeId',
'p.rating_scale_id', 'p.pacra_action as Action' , 'og_companies.name as Entity',
'og_main_sectors.title as Industry', 'p.detail_report as DetailReport',
)
->get();
$jcr['jcr'] = DB::table('og_ratings_jcr as t')
->select('t.client_id as id',
't.jcr_dissemination_date as Dissemination',
't.rating_type_id as ratingTypeId',
't.rating_scale_id',
't.jcr_action as Action' , 'og_companies.name as Entity',
't.press_release_jcr as PressRelease',
'og_actions.title as RatingAction',
'og_outlooks.title as Outlook',
'og_sterms.title as RatingST',
'og_lterms.title as RatingLT',
'og_segments.title',
'og_rating_scales.title as RatingScale',
'og_fund_types.title as fundtype',
't.isActive as isActive' , 'og_main_sectors.title AS Industry' )
->get();
return view('RatingsPacra', compact('pacra' , 'jcr'));
}
答案 0 :(得分:1)
我发现你错过了表格之间的关系,以及@apokryfos提到的额外,
。
尝试类似:
public function ratingData()
{
$pacra['pacra'] = \DB::connection()
->table('og_ratings')
->leftJoin('og_companies', 'og_companies.id', '=', 'og_ratings.og_companies_id')
->leftJoin('og_main_sectors', 'og_main_sectors.id', '=', 'og_ratings.og_main_sectors_id')
->select([
'og_ratings.client_id as Id',
'og_ratings.ppl_date as Ppl',
'og_ratings.notification_date as Notification',
'og_ratings.dissemination_date as Dissemination',
'og_ratings.rating_type_id as ratingTypeId',
'og_ratings.rating_scale_id',
'og_ratings.pacra_action as Action',
'og_companies.name as Entity',
'og_main_sectors.title as Industry',
'og_ratings.detail_report as DetailReport',
])
->get();
$jcr['jcr'] = \DB::connection()
->table('og_ratings_jcr')
->leftJoin('og_actions', 'og_actions.id', '=', 'og_ratings_jcr.og_actions_id')
->leftJoin('og_outlooks', 'og_outlooks.id', '=', 'og_ratings_jcr.og_outlooks_id')
->leftJoin('og_sterms', 'og_sterms.id', '=', 'og_ratings_jcr.og_sterms_id')
->leftJoin('og_lterms', 'og_lterms.id', '=', 'og_ratings_jcr.og_lterms_id')
->leftJoin('og_segments', 'og_segments.id', '=', 'og_ratings_jcr.og_segments_id')
->leftJoin('og_rating_scales', 'og_rating_scales.id', '=', 'og_ratings_jcr.og_rating_scales_id')
->leftJoin('og_fund_types', 'og_fund_types.id', '=', 'og_ratings_jcr.og_fund_types_id')
->select([
'og_ratings_jcr.client_id as id',
'og_ratings_jcr.jcr_dissemination_date as Dissemination',
'og_ratings_jcr.rating_type_id as ratingTypeId',
'og_ratings_jcr.rating_scale_id',
'og_ratings_jcr.jcr_action as Action', 'og_companies.name as Entity',
'og_ratings_jcr.press_release_jcr as PressRelease',
'og_actions.title as RatingAction',
'og_outlooks.title as Outlook',
'og_sterms.title as RatingST',
'og_lterms.title as RatingLT',
'og_segments.title',
'og_rating_scales.title as RatingScale',
'og_fund_types.title as fundtype',
'og_ratings_jcr.isActive as isActive', 'og_main_sectors.title AS Industry',
])
->get();
return view('RatingsPacra', compact('pacra', 'jcr'));
}
您应该在表中更改表之间的外键。
你仍然可以继续使用表别名,我只是不想使用它们,因为它们有时在Laravel / Doctrine Dbal中没有按预期工作。
我还将方法名称从ratingdata
更新为ratingData
,以符合PSR-1标准:
https://www.php-fig.org/psr/psr-1/
你也可以回复\DB:connection()->table(..
到DB::table(...
,这只是一种自以为是的方式。
