使用jedis恢复排序集时,是否保留了订单?(Is order preserved in set when recovering sorted sets using jedis?)

我使用Java Redis客户端“Jedis”。

例如,当使用zrange获取有序集时,客户端指定它返回一个Set,根据定义,它不具有保证。

这个老问题提到了问题,但我没有找到它是否已经解决的参考。

我可以这样做,知道订单会被保留吗?

Set<String> results = jedisCli.zrange(key, start, end);
MyObject[] requestedOrderedObjects = new MyObject[results.size];
int i = 0;
foreach(String result: results) {
    requestedOrderedObjects[i++] = MyObject.loadFromString(result);
}
return requestedOrderedObjects;

感谢您的任何帮助。


I use Java Redis client "Jedis".

When getting a sorted set using zrange for example, the client specifies it returns a Set which by definition has no oredering guarantee.

this old question mentions the problem but I have found no reference to whether it is resolved.

Can I do this and know order will be preserved?

Set<String> results = jedisCli.zrange(key, start, end);
MyObject[] requestedOrderedObjects = new MyObject[results.size];
int i = 0;
foreach(String result: results) {
    requestedOrderedObjects[i++] = MyObject.loadFromString(result);
}
return requestedOrderedObjects;

Thank you for any help.

在将字典传递给模板之前需要强制转换为SafeString。 无需使用json模块。

与此处相同的问题: 在django模板中使用JSON

视图

from django.utils.safestring import SafeString
...
def load_timeline_events(request):
    ....
    return render('timeline.html', {'EVENTS':SafeString(raw_events)})

Need to cast as SafeString before passing the dictionary to the template. No need to use the json module.

Same problem as found here: Using JSON in django template

View

from django.utils.safestring import SafeString
...
def load_timeline_events(request):
    ....
    return render('timeline.html', {'EVENTS':SafeString(raw_events)})
