Question

我有这个：

#include <boost/signals2.hpp>
#include <iostream>
#include <memory>

struct MySlot
{
  void operator()(std::unique_ptr<int>&& input) const
  {
    std::cout << "Signaled " << *input.get();
  }
};

int main(int argc, char* argv[])
{
  boost::signals2::signal<void(std::unique_ptr<int>)> signal;

  signal.connect(MySlot());

  auto ptr = std::make_unique<int>(20);
  signal(std::move(ptr));
}

但我想要的是这样的：

$comments = ArticleComments::orderBy('created_at','desc')->with('user')->with('article')->with('article.translations')->paginate(10);

我如何获得$comments = ArticleComments::orderBy('created_at','desc')->with('user')->with('article')->with('article.translations')->whereHas('article.translations',function($query) use($default_language_id){ $query->where('language_id','=', $default_language_id )->first(); })->paginate(10);但仅限于默认语言？现在我得到所有语言的所有翻译

您不需要在此处使用translations。使用eager load contraining功能。此代码仅为默认语言加载ArticleComments::orderBy('created_at','desc') ->with(['user', 'article', 'article.translations' => function($q) use(default_language_id) { $q->where('language_id', $default_language_id); }])->paginate(10);：

angular.module('SCtrl', ['ng-fusioncharts']).controller('SCtrl', function($scope, $http) {

    //Get All errors.
    $http({
        method: 'GET',
        url: 'node/errors'
    }).then(function successCallback(response) {
        $scope.notifications = response.data;
        console.log($scope.notifications);
    }, function errorCallback(response) {

    });
}

如何使用和哪里在一起？
