Twig Runtime Error: Impossible to invoke a method (“test”) on a string variable

Question

I have the following twig template (the code is in the same file):

{% macro renderJob(fields) %}
    // renders the job UI block, but I've removed it for simplicity
    Hello world.
{% endmacro %}
{% block _jobs_widget %}
    <div id="jobsContainer">
        {% for fields in form.children %}
            {% dump fields %}
            {{ _self.renderJob(fields) }}
        {% endfor %}
    </div>
{% endblock %}

For some reason, after upgrading to twig/twig = v2.1.0 I'm receiving the follwing error:

Impossible to invoke a method ("renderJob") on a string variable ("@AppBundle/Jobs/form/job.html.twig").

I have been trying to figure out what's causing this without any luck. This used to work just fine in 1.3.x . The fields variable contains the proper data, but it appears it can't pass it to the renderJob macro or it can't find the macro (which is kind of odd)?

Answer 1

Have you tried the following ?

{% import _self as renderJobMacro %}

{% macro renderJob(fields) %}
    // renders the job UI block, but I've removed it for simplicity
    Hello world.
{% endmacro %}

{% block _jobs_widget %}
    <div id="jobsContainer">
        {% for fields in form.children %}
            {{ renderJobMacro.renderJob(fields) }}
        {% endfor %}
    </div>
{% endblock %}

No clue why it worked before, but you still need to import the macro before you can use it:

{% macro renderJob(fields) %}
    // renders the job UI block, but I've removed it for simplicity
    Hello world.
{% endmacro %}

{% import _self as macro %}

{% block _jobs_widget %}
    <div id="jobsContainer">
        {% for fields in form.children %}
            {% dump fields %}
            {{ macro.renderJob(fields) }}
        {% endfor %}
    </div>
{% endblock %}

I think _self is depricated from twigg 2.0, May be you need to check without _self .

Check {{ renderJob(fields) }} instead of {{ _self.renderJob(fields) }}
