這可能是一個簡單的問題，但我一直在盯着這個代碼年齡和嘗試不同的變化，但我似乎無法解決它。angularJS Rails應用程序，通過陣列的問題
我正在循環播放由遊戲中的玩家組成的JSON哈希。每個玩家可以是普通玩家或預備玩家。然而問題在於當前的用戶播放器。我需要在ng-repeat中找到當前遊戲的當前玩家（這是沒有問題的），然後將他/她設置爲預備玩家或普通玩家。那就是問題所在。我有一個if和else語句來判斷當前用戶是否保留，然後將boolean game.current_user.reserve設置爲true或false。問題在於，如果當前用戶在多個遊戲中並且將布爾值設置爲if/else語句的最後一個，則循環似乎經歷if和else兩者。希望你明白我的意思:)
下面是代碼：
Game.get().then(function(games){
$scope.games = games;
angular.forEach(games, function(game, gameIndex){
game.tees = [];
Tee.query({game_id: game.id}).then(function(tees){
game.tees = tees;
})
PlayersGame.query({players: game.id}).then(function(players){
game.players = [];
game.reserves = [];
angular.forEach(players, function(value, index){
if(value.reserve == false){
var id = value.id;
User.get(value.userId).then(function(player){
game.players.push(player);
if(player.id == $scope.current_user.id){
game.current_user = $scope.current_user;
game.current_user.reserve = false;
}
});
}else{
User.get(value.userId).then(function(reserve){
game.reserves.push(reserve);
if(reserve.id == $scope.current_user.id){
game.current_user = $scope.current_user;
game.current_user.reserve = true;
}
});
}
});
});
})
});
我使用$ scope.game在NG-重複，然後我要更多的孩子NG-重複使用$範圍。 game.players和$ scope.game.reserves。當前用戶想要取消他們的遊戲時，我可以成功刪除記錄服務器端，但我無法正確地在客戶端做到這一點。我無法找到正確的記錄刪除$ scope.game 這裏是取消遊戲功能。
$scope.cancelGame = function(gameId, current_user, gameIndex){
var confirmation = confirm("Are you sure that you want to cancel your booking?");
if(confirmation){
PlayersGame.query({game_id : gameId, user_id: current_user.id}).then(function(game){
game[0].delete().then(function(){
if(current_user.reserve = true){console.log($scope.games[gameIndex]);
angular.forEach($scope.games[gameIndex].reserves, function(value,index){
if(value.id == current_user.id){
$scope.games[gameIndex].reserves.splice(index,1);
}
})
}else{console.log($scope.games[gameIndex]);
angular.forEach($scope.games[gameIndex].players, function(value,index){
if(value.id == current_user.id){
var removed = $scope.games[gameIndex].players.splice(index,1);console.log(removed);
}
})
}
});
});
$scope.games[gameIndex].current_user = [];
}
}
我剛剛在循環中做了一些控制檯日誌的測試。在我看來，循環似乎很好。我認爲問題在於重複。我認爲在循環運行後，變量game.current_user.reserve被設置在ng-repeat中。這可能嗎？
這是在任何情況下，HTML：
