Laravel 有条件地预先加载，使用或查询

Question

我有这个查询：

    $paginated = File::whereIn('model_id', $channelRules->pluck('id'))
        ->with('campaignChannelRule.channel.channel')
        ->where('model_type', 'campaign_channel_rule')
        ->orWhere(function($query) use($campaign) {
            $query->where('model_type', 'campaign')->where('model_id', $campaign->id);
        })
        ->paginate(15);

问题是，当文件是model_type campaign时，我不想急切加载->with('campaignChannelRule.channel.channel') 。

我怎样才能做到这一点？

谢谢

我认为这是因为查询的语法错误，试试这个：

$paginated = File::with('campaignChannelRule.channel.channel')
        ->whereIn('model_id', $channelRules->pluck('id'))
        ->where(function ($w) use ($campaign) {
            $w->where('model_type', 'campaign_channel_rule')
                ->orWhere(function ($query) use ($campaign) {
                    $query->where('model_type', 'campaign')->where('model_id', $campaign->id);
                });
            })
        ->paginate(15);
