Volt not including file if path is concatenated

问题

I'm trying to iterate through a Model collection in volt:

{% if model.elements|length > 0 %}
    {% for element in model.getElements() %}
        {% include "partials/panels/edit-" ~ element.getType() ~ ".volt" %}
    {% endfor %}
{% endif %}

The type can be text or images. If i use the above code, i get the error:

View '/path/to/phalcon/apps/frontend/views/partials/panels/edit-image.volt' was not found in the views directory

I'm sure that the file exists, since if i changethe include, it'll work:

{% include "partials/panels/edit-image.volt" %}

It'll also fail on:

{% include "partials/pandels/edit-" ~ "image.volt %} 

What is the reason that the first version is producing that error? ( I know i could just use ifs.. But theres quite a list of element types later on. )

回答1:

This will not work.

To include view dynamically use partial:

{% if model.elements|length > 0 %}
    {% for element in model.getElements() %}
        {{ partial( "partials/panels/edit-" ~ element.getType() ) }}
    {% endfor %}
{% endif %}

There is no '.volt' since partial will add it.
