How the depth of a twig template is calculated by SensioLabsInsight - symfony

Question

I analyzed the quality of my php project with SensioLabsInsight and I get this error:
Twig templates should not contain business logic
Template too complex, depth of 13 is reached but only 5 is allowed.
for this template :
{% macro row(context, blockinfo, chapterContainerClass, chapterHeadingClass, chapterContentClass) %}
{% set step = context.step %}
{% set panel = blockinfo.panel %}
{% set simu = step.simulator %}
<div id="{{ step.name }}-panel-{{ panel.id }}-blockinfo-{{ blockinfo.id }}" class="blockinfo-container">
<div class="blockinfo-label">
<h2>{{ blockinfo.label }}</h2>
</div>
<div class="blockinfo-chapters">
{% for chapter in blockinfo.chapters %}
{%- if chapter.displayable or (step.dynamic and context.script == 1) or (simu.dynamic and step.id == 0) -%}
<div id="{{ step.name }}-panel-{{ panel.id }}-blockinfo-{{ blockinfo.id }}-chapter-{{ chapter.id }}" class="chapter-container {{ chapterContainerClass }}" data-chapter-id="{{ chapter.id }}">
<div class="chapter-label {{ chapterHeadingClass }}">
<h3>
{%- if chapter.collapsible -%}
<button id="ui-collapse-{{ step.name }}-panel-{{ panel.id }}-blockinfo-{{ blockinfo.id }}-chapter-{{ chapter.id }}" role="button" aria-expanded="false" class="btn btn-collapse" data-toggle="collapse" type="button" data-target="#{{ step.name }}-panel-{{ panel.id }}-blockinfo-{{ blockinfo.id }}-chapter-{{ chapter.id }}-sections"><span>
{% endif %}
{{ chapter.label }}
{%- if chapter.collapsible -%}
</span></button>
{% endif %}
</h3>
</div>
<div id="{{ step.name }}-panel-{{ panel.id }}-blockinfo-{{ blockinfo.id }}-chapter-{{ chapter.id }}-sections" class="blockinfo-chapter-sections {{ chapterContentClass }}{%- if chapter.collapsible %} collapse{%- endif -%}">
{% for section in chapter.sections %}
{%- if section.displayable or (step.dynamic and context.script == 1) or (simu.dynamic and step.id == 0) -%}
<div id="{{ step.name }}-panel-{{ panel.id }}-blockinfo-{{ blockinfo.id }}-chapter-{{ chapter.id }}-section-{{ section.id }}" class="section-container">
{%- if section.label is not empty -%}
<div class="section-label">
<h2>{{ section.label }}</h2>
</div>
{% endif %}
<div class="section-body-container">
{%- if section.annotations is not empty %}
<div id="{{ step.name }}-panel-{{ panel.id }}-blockinfo-{{ blockinfo.id }}-chapter-{{ chapter.id }}-section-{{ section.id }}-annotations" class="section-annotations">
{{ simu.paragraphs(section.annotations)|jscode }}
</div>
{% endif %}
<div id="{{ step.name }}-panel-{{ panel.id }}-blockinfo-{{ blockinfo.id }}-chapter-{{ chapter.id }}-section-{{ section.id }}-content" class="section-content{%- if section.annotations is not empty %} with-annotations{%- endif -%}">
{{ simu.paragraphs(section.content)|jscode }}
</div>
</div>
</div>
{% endif %}
{% endfor %}
</div>
</div>
{% endif %}
{% endfor %}
</div>
</div>
{% endmacro %}
I don't know how to solve this problem because i don't know how the depth of a twig template is calculated by SensioLabsInsight
Thank you in advance for your help

Answer 1

You should not use conditional statements in twig like :
{%- if section.annotations is not empty %}
you need to write this statements in controller or in a PHP file something like this :
public function isempty()
{
if($this->label== "") {
$mylabel = "empty";
}
else {
$mylabel = "notempty";
}
return $myGender;
}
And this is how to avoid business logic in Twig templates
