动态显示树枝中的表格(Displaying table in twig dynamically)

动态显示树枝中的表格(Displaying table in twig dynamically)

我试图在不知道对象结构的情况下显示User对象中的所有用户（因此我也可以使用同一个表来显示其他对象集合）。

这就是“静态”看起来的样子：

<table> <tr> <td>id</td> <td>username</td> </tr> {% for item in entities %} <tr> <td>{{ item.id }}</td> <td>{{ item.username }}</td> </tr> {% endfor %} </table>

我想要做的是如下（这只是为了显示我正在尝试做的事情，但它甚至不接近工作）：

<table> <tr> {% for property_title in entities.item[0] %} <td>{{ property_title }}</td> {% endfor %} </tr> {% for item in entities %} <tr> {% for property in item %} <td>{{ property.value }}</td> {% endfor %} </tr> {% endfor %} </table>

结果应如下所示：

<table> <tr> <td>id</td> <td>username</td> </tr> <tr> <td>1</td> <td>Mike123</td> </tr> <tr> <td>2</td> <td>jesica2</td> </tr> </table>

PD：这是我的第一篇文章，如果我错过了什么，请道歉。

I'm trying to display all the users in my User object without knowing the structure of the object (so I can use the same table to display other collection of objects as well).

This is what it would look 'statically':

<table> <tr> <td>id</td> <td>username</td> </tr> {% for item in entities %} <tr> <td>{{ item.id }}</td> <td>{{ item.username }}</td> </tr> {% endfor %} </table>

What i would want to do is something as follows (this is just to display what I'm trying to do, but its not even close to working):

<table> <tr> {% for property_title in entities.item[0] %} <td>{{ property_title }}</td> {% endfor %} </tr> {% for item in entities %} <tr> {% for property in item %} <td>{{ property.value }}</td> {% endfor %} </tr> {% endfor %} </table>

Result should be something as follows:

<table> <tr> <td>id</td> <td>username</td> </tr> <tr> <td>1</td> <td>Mike123</td> </tr> <tr> <td>2</td> <td>jesica2</td> </tr> </table>

PD: this is my first post, so apologies if I missed something.

制作一个枝条扩展名，返回您想要的字段列表，这样您就可以使用php来获取字段。 之后使用twig的属性函数

{{attribute（object，fields）}}调用对象上的getter

文档：

http://symfony.com/doc/current/cookbook/templating/twig_extension.html http://twig.sensiolabs.org/doc/functions/attribute.html

例：

{% set temp = entities|first %} {% set fields = getObjectFields(temp) %} <tr> {% for property_title in fields %} <td>{{ property_title }}</td> {% endfor %} </tr> {% for item in entities %} <tr> {% for field in fields %} <td>{{ attribute(item, field) }}</td> {% endfor %} </tr> {% endfor %}

Make a twig extension that returns a list of the fields you want, that way you can use php to get the fields. After that use twig's attribute function

{{ attribute(object, fields) }} to call the getters on the object

docs:

http://symfony.com/doc/current/cookbook/templating/twig_extension.html http://twig.sensiolabs.org/doc/functions/attribute.html

example:

{% set temp = entities|first %} {% set fields = getObjectFields(temp) %} <tr> {% for property_title in fields %} <td>{{ property_title }}</td> {% endfor %} </tr> {% for item in entities %} <tr> {% for field in fields %} <td>{{ attribute(item, field) }}</td> {% endfor %} </tr> {% endfor %}
