[英]Laravel 5.3 Eloquent where clause on joining table from parent model
I have a fabrics table which links to one brand and one season. 我有一个织物桌,链接到一个品牌和一个季节。 Running
App\\fabrics::with('brand', 'season')->get()
gets me all the fabrics and their brand and season information which is fine (see below). 运行
App\\fabrics::with('brand', 'season')->get()
获取所有面料及其品牌和季节信息,这很好(见下文)。
I want to get fabrics based on the season id. 我想根据季节ID获得面料。 I tried:
我试过了:
App\\fabrics::with('brand', 'season')->where('season.id', '1')->get()
but this doesn't work. 但这不起作用。
Column not found: 1054 Unknown column 'season.id' in 'where clause' (SQL: select * from `fabrics` where `season`.`id` = 1)'
Is it possible to get fabrics and filter by one of its relationships? 是否可以通过其中一种关系获得面料和过滤器?
Obviously I can get the fabrics from the season model App::season but I was wondering if it can be achieved from its parent (fabrics) model. 显然我可以从季节模型App :: season获得面料,但我想知道它是否可以通过其母(面料)模型实现。
All the information from App\\fabrics::with('brand', 'season')->get() 来自App \\ fabrics :: with('brand','season') - > get()的所有信息
>>> App\fabrics::with('brand', 'season')->get()

Use the closure for eager loads contraining : 使用封闭装置来控制急切负荷 :
App\fabrics::with(['brand', 'season' => function($q) use($seasonId) {
$q->where('id', $seasonId);
}])->get();
If you want to filter fabrics by season ID, use whereHas()
: 如果
whereHas()
季节ID过滤结构,请使用whereHas()
:
App\fabrics::with('brand', 'season')
->whereHas('season', function($q) use($seasonId) {
$q->where('id', $seasonId);
})->get();
