Php 仅laravel过滤器嵌套条件

我只想过滤dealTransactions中的嵌套值

简单地说，Merchant Wands only dealTransactions提供了交易日期

我试过下面这样的方法，但不起作用

dates = ['2019-01-01', '2019-01-02', '2019-01-03', '2019-01-04', '2019-01-05'];


$merchant = Merchant::with(['deals.dealTransactions'])->where('slug', $slug)
                ->whereHas('deals.dealTransactions', function($query) use ($dates) {
                    foreach($dates as $date) {
                        $query->where('date', '=', $date);
                    }                        
                })
                ->first();




deal_transactions table

id, deal_id, date 


deals table 
id, merchant_id, 


merchants table
id, many columns for merchant

谢谢

如果我正确理解了您的模式，这可能会有帮助：

// Here you define the scope that will be used to select & eager load.
$transactionsScope = function ($q) use ($dates) {
    return $q->whereIn('date', $dates);
};
// All merchant of slug in/with that transaction's scope.  
$merchant = Merchant::where('slug', $slug)
    ->whereHas('deals', function ($q) use ($transactionsScope) {
        return $q->whereHas('dealTransactions', $transactionsScope);
    })
    ->with(['deals' => function ($q) use ($transactionsScope) {
        return $q->with('dealTransactions', $transactionsScope);
    }])
    ->firstOrFail();

您应该能够通过嵌套关系上的“急切加载”约束来执行此操作：

$merchant = Merchant::where('slug', $slug)
    ->with(['deals.dealTransactions' => function ($query) use ($dates) {
        $query->whereIn('date', $dates);
    }])->first();

谢谢你的回复。根据你的回答，我有了一个想法。谢谢。谢谢你的回复。根据你的回答，我有了一个想法。谢谢。您只想加载dealTransaction日期与日期匹配的交易，或者您只想加载dealTransaction，如果它有匹配的日期？@lagbox我想加载交易和dealTransactions，但dealTransactions必须与日期匹配。谢谢，请再澄清一下。。。无论发生什么情况，您都希望加载交易，但这些交易中的交易必须只与这些日期匹配？@lagbox Yes完全正确！您只想加载dealTransaction日期与日期匹配的交易，或者您只想加载dealTransaction日期匹配的交易？@lagbox我想同时加载交易和dealTransactions，但dealTransactions必须与日期匹配。谢谢，请进一步澄清。。。无论发生什么情况，您都希望加载交易，但这些交易中的交易必须只与这些日期匹配？@lagbox Yes完全正确！
