小枝忘记阵列密钥 [英] Twig forgets array-keys

问题描述

我在Symfony2的树枝一个奇怪的问题。我使用下面的数组：

I have a weird problem with twig in Symfony2. I am using the following array:

[days] => Array
    (
        [1] => Array
            (
                [money] => 9
            )

        [2] => Array
            (
                [money] => 21
            )

        [3] => Array
            (
                [money] => 38
            )

        [4] => Array
            (
                [money] => 6
            )

        [18] => Array
            (
                [money] => 6
            )

        [19] => Array
            (
                [money] => 3
            )

        [31] => Array
            (
                [money] => 11
            )

    )

要测试这个我用下面的code

to test this I used the following code

{% for key in days %}
  {{ key }}<br>
{% endfor %}

但输出显示以下

0
1
2
3
4
5
6

但它应该是这样的。

but it should look like this

1
2
3
4
18
19
31

看起来像树枝将创建新的索引一个新的数组。有没有办法摆脱阵列右手食指？

Looks like twig creates a new array with new indexes. Is there a way to get the right index from array?

使用的var_dump（$天）在PHP中，我可以看到正确的索引，这样的问题，以小枝有关。

With var_dump($days) in php I can see the right index, so the "problem" is related to twig.

推荐答案

它不是树枝的关系，它的使用embeddedDocuments教义，MongoDB中一个已知的差距。教义不能从embeddedDocuments处理键值，将重新排序，从0开始键，并因此忽略右边键值。谢谢你的好意的帮助：）

It's not related on twig, it's a known gap in doctrine-mongodb using embeddedDocuments. Doctrine can't handle key-Values from embeddedDocuments, it will reorder the keys beginning from 0 and will so ignore the right key-values. Thank you anyway for your help :).
