[英]How to get multiple whereBetween records in Laravel
我在Laravel 5.4
上构建了一个小型应用程序,在该应用程序中,我从诸如此类的关系中获取数据集:
$meetings = Company::where('name', 'Atlanta Ltd')
->withCount(['interactions as investors'=> function ($q) {
$q
->whereBetween('schedule', [Carbon::now()->subMonths(6), Carbon::now()->subMonths(1)])
->whereHas('contactsAssociation', function ($q) {
$q->whereHas('company', function ($q) {
$q->where('type', 'like', 'Investor');
});
});
}])->get()
->transform(function ($company) {
$company->investors_count = $company->interactions
->pluck('investors_count')
->sum();
return $company;
});
目前,我正在获取特定日期之间的互动次数作为investor_counts,我想获取某些日期字段之间的计数,即假设我想连续六个月获取数据,我的意思是六个不同月的数据像这样的东西:
->whereBetween('schedule', [Carbon::now()->subMonths(6), Carbon::now()->subMonths(5)])
和
->whereBetween('schedule', [Carbon::now()->subMonths(5), Carbon::now()->subMonths(4)])
和
->whereBetween('schedule', [Carbon::now()->subMonths(4), Carbon::now()->subMonths(3)])
清单与上述差异相似。 而且我不想实现多个foreach循环, Laravel Collection
有没有解决的办法,我可以在其中操纵这些数据以获取输出。 请指导我。 谢谢。
编辑:让我以更好的方式进行说明,目前,我正在使用以下代码来获取所需的数据:
public function investorGraphData(Request $request)
{
$weekInvestorData = $weekResearchData = [];
if($request->timeFormat == 'month')
{
for($i=0; $i<6; $i++)
{
$meetings = Company::where('name', $request->client)
->withCount(['interactions as investors'=> function ($q) use($i) {
$q
->whereBetween('schedule', [Carbon::now()->subMonth($i+1), Carbon::now()->subMonth($i)])
->whereHas('contactsAssociation', function ($q) {
$q->whereHas('company', function ($q) {
$q->where('type', 'like', 'Investor');
});
});
}])
->withCount(['interactions as research' => function($q) use($i) {
$q
->whereBetween('schedule', [Carbon::now()->subMonth($i+1), Carbon::now()->subMonth($i)])
->whereHas('contactsAssociation', function ($q) {
$q->whereHas('company', function ($q) {
$q->where('type', 'like', 'Research');
});
});
}])
->get();
$weekInvestorData[] = $meetings[0]->investors_count;
$weekResearchData[] = $meetings[0]->research_count;
}
return response()->json(['investor' => $weekInvestorData, 'research' => $weekResearchData], 200);
}
elseif ($request->timeFormat == 'week')
{
for($i=0; $i<6; $i++)
{
$meetings = Company::where('name', $request->client)
->withCount(['interactions as investors'=> function ($q) use($i) {
$q
->whereBetween('schedule', [Carbon::now()->subWeek($i+1), Carbon::now()->subWeek($i)])
->whereHas('contactsAssociation', function ($q) {
$q->whereHas('company', function ($q) {
$q->where('type', 'like', 'Investor');
});
});
}])
->withCount(['interactions as research' => function($q) use($i) {
$q
->whereBetween('schedule', [Carbon::now()->subWeek($i+1), Carbon::now()->subWeek($i)])
->whereHas('contactsAssociation', function ($q) {
$q->whereHas('company', function ($q) {
$q->where('type', 'like', 'Research');
});
});
}])
->get();
$weekInvestorData[] = $meetings[0]->investors_count;
$weekResearchData[] = $meetings[0]->research_count;
}
return response()->json(['investor' => $weekInvestorData, 'research' => $weekResearchData], 200);
}
else
return response()->json(['message' => 'No input given'], 200);
}
有什么办法可以通过收集来缩短这段代码?
您可以尝试为列指定其他名称,
例如 :
$meetings = Company::where('name', 'Atlanta Ltd')
->withCount(['interactions as investors'=> function ($q) {
$q
->whereBetween('schedule as schedule6to5', [Carbon::now()->subMonths(6), Carbon::now()->subMonths(5)])
->whereBetween('schedule as schedule5to4', [Carbon::now()->subMonths(5), Carbon::now()->subMonths(4)])
->whereBetween('schedule as schedule4to3', [Carbon::now()->subMonths(4), Carbon::now()->subMonths(3)])
->whereHas('contactsAssociation', function ($q) {
$q->whereHas('company', function ($q) {
$q->where('type', 'like', 'Investor');
});
});
}])->get()
->transform(function ($company) {
$company->investors_count = $company->interactions
->pluck('investors_count')
->sum();
return $company;
});
也许这会工作。
