Output array in Twig

I trying to output an array from the database to the screen. In my entity:

/**
 * @ORM\Column(type="array", nullable=true)
 */
private $category;

In my twig template:

{% for category in user.profile.category %}
    {{ category }}
{% endfor %}

Error: Array to string conversion in ...

Where is my mistake?

Solution

  • TWIG doesn't know how you want to display your table.

    By the way, you should consider naming your variable $categories instead of $category, as you table contains several categories.

    Then try this:

    {% for category in user.profile.categories %}
   {{ category }}
{% endfor %}

    If my answer doesn't help, please give us the structure of your array (is there any keys or sub-arrays in you table or is it just a list?)
