这是我第一次尝试在Digitalocean上部署Rails应用程序。我正在为我的DBM使用Apache服务器和PostgreSQL。我已经有一个域名，我正在尝试用于我的应用程序。每当我尝试使用我获得的域名访问我的网站时：
We're sorry, but something went wrong.
If you are the application owner check the logs for more information.
这些是我得到的日志。

我已经尝试了很多东西，但找不到问题所在。如果有人能帮助我，我感激不尽！

我可以看到你有PG错误，你可以做出这些改变：
var map;
function initialize() {
var mapOptions = {
zoom: 12,
center: new google.maps.LatLng(-7.045000, 110.426000),
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
setMarkers(map, markers);
};
var markers = [['MSC SEMARANG', -7.045000, 110.426000, 1107, '../images/tower2.png'], ['Srondol', -7.062000, 110.418000, 1108, '../images/tower2.png']];
var infowindow = new google.maps.InfoWindow();
function setMarkers(map, locations) {
var marker, i;
for (i = 0; i < locations.length; i++) {
var markers = locations[i];
var myLatLng = new google.maps.LatLng(locations[i][1], locations[i][2]);
var marker = new google.maps.Marker({
position: myLatLng,
map: map,
title: locations[i][0],
zIndex: locations[i][3],

});
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
infowindow.setContent(locations[i][0]);
infowindow.open(map, marker);
changeTitle(this);
}
})(marker, i));
}
};
function changeTitle(x) {
var count = 0;
var titles = x.get('title');
x.set('title', 'this is chaged');
};
google.maps.event.addDomListener(window, 'load', initialize);
