问题描述

我有 2 个相关的表，InProducto 和 InUnidadMedida，其中 InProducto 与 ManyToOne 和 InUnidadMedida 相关.我想知道如何获取我的相关 ID 的名称以将其显示在列表中.

I have 2 tables related, InProducto and InUnidadMedida, which InProducto is related ManyToOne with InUnidadMedida. I want to know how can I get the name of my related ID to show it in the list.

索引树枝

        {% for entity in entities %}
            <tr>
                <td>{{ entity.idProducto }}</td>
                <td>{{ entity.nombre }}</td>
                <td>{{ entity.idUnidadMedida }}</td>
                <td>{{ entity.costoPromedio }}</td>
                <td>{{ entity.idSubLinea }}</td>
                <td>{{ entity.idTipoProducto }}</td>
                <td>{{ entity.precio1 }}</td>
                <td>
                    {% if entity.inventariable == 0 %}
                        No
                    {% elseif entity.inventariable == 1 %}
                        Sí
                    {% endif %}
                </td>
                <td>
                    {% if entity.facturable == 0 %}
                        No
                    {% elseif entity.facturable == 1 %}
                        Sí
                    {% endif %}
                </td>
                <td>
                    {% if entity.activo == 0 %}
                        No
                    {% elseif entity.activo == 1 %}
                        Sí
                    {% endif %}
                </td>
                <td class = "actions">
                    <a href="{{ path('inproducto_show', { 'id': entity.idProducto }) }}" class = "btn btn-sm btn-info">ver</a>
                    <a href="{{ path('inproducto_edit', { 'id': entity.idProducto }) }}" class = "btn btn-sm btn-primary">editar</a>
                </td>
            </tr>
        {% endfor %}

其中 {{ entity.idSubLinea }} 和 {{ entity.idUnidadMedida }} 是相关字段，我想显示每个类别的名称.

Where {{ entity.idSubLinea }} and {{ entity.idUnidadMedida }} are the related fields and I want to display the names of each category.

目前它会打印 ID.

推荐答案

It's just {{ entity.unidadMedida.name }} (给定属性是 $name)

It's just {{ entity.unidadMedida.name }} (given the property is $name)

您也可以通过仅制作 {{ entity.unidadMedida }} 并在 InUnidadMedida 实体中制作方法 __toString 来使其更简单

You can also make it a bit simpler by making just {{ entity.unidadMedida }} and making a method __toString in InUnidadMedida Entity

...
public function __toString() 
{
   return $this->name;
}
...
