I am struggling with creating a macro to automatically generate section number and subsection numbers. I had thought the snippet below would work but it is failing to assign the value if not already set. I am sure this is obvious but my lack of jinja experience is showing... or perhaps lack of Python experience... or both!
I get this error.
{% set sectionnumber.value = sectionnumber.value + 1 %}
jinja2.exceptions.TemplateRuntimeError: cannot assign attribute on non-namespace object
{% macro getsectionnumber(type) -%}
{% if subsectionnumber is none %}
{% if sectionnumber is none %}
{% set sectionnumber = namespace(value=0) %}
{% endif %}
{% set subsectionnumber = namespace(value=0) %}
{% endif %}
{% if type == 'section' %}
{% if sectionnumber is none %}
{% set sectionnumber = namespace(value=0) %}
{% endif %}
{% set sectionnumber.value = sectionnumber.value + 1 %}
{{ sectionnumber.value }}
{% endif %}
{% if type == 'subsection' %}
{% set subsectionnumber.value = subsectionnumber.value + 1 %}
{{ sectionnumber.value }}.{{ subsectionnumber.value }}
{% endif %}
my template:
template = """
{% set sectionnumber = namespace(value=0) %}
{% set subsectionnumber = namespace(value=0) %}
{% macro getsectionnumber(type) -%}
{% if type == 'section' %}
{% set sectionnumber.value = sectionnumber.value + 1 %}
{{ sectionnumber.value }}
{% endif %}
{% if type == 'subsection' %}
{% set subsectionnumber.value = subsectionnumber.value + 1 %}
{{ sectionnumber.value }}.{{ subsectionnumber.value }}
{% endif %}
{% endmacro %}
{{ getsectionnumber('section') }}
{{ getsectionnumber('subsection') }}
{{ getsectionnumber('subsection') }}
{{ getsectionnumber('section') }}
{{ getsectionnumber('subsection') }}
{{ getsectionnumber('subsection') }}
"""
print the template:
print(Template(template).render())
result:

Hey iam currently trying to get the description of the first menu navigation in Shopware 6.
For that i use the array page.header.navigation.active.breadcrumb and use its key in page.header.navigation.tree[key].description, but my key value is empty.
Thats happening due to the key beeing empty for no reason.
Heres my Code:
{% sw_extends "#Storefront/storefront/section/cms-section-sidebar.html.twig" %}
{% set topMenu = null %}
{% for key, value in page.header.navigation.active.breadcrumb %}
{% if loop.index == 2 %}
{% set topMenu = value %}
{# {% set topMenuDescription = page.header.navigation.tree[key].category.description %} #}
{% set topMenuDescription = key %}
{% endif %}
{% endfor %}
{% set currentMenu = page.header.navigation.active.breadcrumb | last %}
{# {% set currentMenu = page.header.navigation.active.name %} #}
{# {% set topMenuDescription = page.header.navigation.active.description %} #}
{# {% if ! topMenuDescription %}
{% set topMenuDescription = page.header.navigation.active.description %}
{% endif %} #}
{% block section_main_content_block %}
<div class="category-top">
<div class="category-banner">
<img src="/media/6a/fd/8b/1632946677/listing-banner.jpg">
<div class="category-banner-headlines">
{% if (currentMenu != topMenu) %}
<h3>{{ topMenu }}<h3>
<h2>{{ currentMenu }}<h2>
{% else %}
<h2 class="sameMenu">{{ currentMenu }}<h2>
{% endif %}
</div>
</div>
<div class="category-description">
<h1>{{ currentMenu }}</h1>
{{ topMenuDescription | trans | raw }}
</div>
</div>
{{ parent() }}
{% endblock %}
Also here is the structure of the key i want to get:
key-i-want-to-get
And heres the description i want to get:
description-i-want-to-get
Sidenote: The description in my example is empty, since i do the showcase in a seperate testing area, where i havent set a description
The reason topMenuDescription is empty is because the variable only exist inside the scope of the {% for %}-loop you've created. Outside this loop the variable doesn't exist.
In order to solve this issue you need to alter the scope of topMenuDescription by defining the variable outside the {% for %}-loop
{% set topMenuDescription = null %}
{% for key, value in page.header.navigation.active.breadcrumb %}
{% if loop.index == 2 %}
{% set topMenu = value %}
{# {% set topMenuDescription = page.header.navigation.tree[key].category.description %} #}
{% set topMenuDescription = key %}
{% endif %}
{% endfor %}
sidenote
You really should enable twig's debug whilst developing as your current snippet would throw a RuntimeError explaining the variable does not exist.
My code is:
{% for key, value in section.items %}
{% for key_t, value_t in title.items %}
{% if value_t.section_id == key|add:"0" %}
<li class="nav-item-header"><div class="text-uppercase font-size-xs line-height-xs">
{{value.title}}</div> <i class="icon-menu" title="Tables"></i></li>
{% endif %}
{% endfor %}
{% endfor %}
I want to break the for loop when if the condition is true. like as
{% for key, value in section.items %}
{% for key_t, value_t in title.items %}
{% if value_t.section_id == key|add:"0" %}
<li class="nav-item-header"><div class="text-uppercase font-size-xs line-height-xs">
{{value.title}}</div> <i class="icon-menu" title="Tables"></i></li>
{{break}}
{% endif %}
{% endfor %}
{% endfor %}
How is it possible? please help me...
There is no way to break out of a for loop in Django Template. However, you can achieve this by setting a variable and adding an if statement on the top like this.
{% set isBreak = False %}
{% for number in numbers %}
{% if 99 == number %}
{% set isBreak = true %}
{% endif %}
{% if isBreak %}
{# this is a comment. Do nothing. #}
{% else %}
<div>{{number}}</div>
{% endif %}
{% endfor %}

How to break "for loop" in Django template
I'm using Twig in Views to rewrite output with condition.
{{ field_illus_lycee }}
{% if field_titre_pour_views is defined %}
{% if field_titre_pour_views is not empty %}
{{ field_titre_pour_views }}
{% endif %}
{% else %}
{{ title }}
{% endif %}
<span class="accroche-admin">{{ body }}</span>
I want to display field_titre_pour_views only if it exists and isn't empty, otherwise the regular title should be displayed. But at this point the regular title isn't displayed.Inspired by this
I don't understand which mistake I've made.
EDIT: correct code
{{ field_illus_lycee }}
{% if field_titre_pour_views is defined %}
{% if field_titre_pour_views is not empty %}
{{ field_titre_pour_views }}
{% else %}
{{ title }}
{% endif %}
{% else %}
{{ title }}
{% endif %}
<span class="accroche-admin">{{ body }}</span>
Sometimes, to ask is to find...this code do the trick:
{% if field_titre_pour_views |default %}
{{ field_titre_pour_views }}
{% else %}
{{ title }}
{% endif %}
Auto fixed :)
Hope it would help someone else.
I'm trying to build a simple dropdown menu on drupal 8 by using twig templates. My problem is that I can't find a way to give the dropdown links a class. Here's my code
{#
/**
* #file
* Theme override to display a menu.
*/
#}
{% import _self as menus %}
{{ menus.menu_links(items, attributes, 0, menu_name) }} {# 1. #}
{% macro menu_links(items, attributes, menu_level, menu_name) %} {# 1. #}
{% import _self as menus %}
{# 1. #}
{%
set menu_classes = [
'c-menu-' ~ menu_name|clean_class,
]
%}
{% if items %}
{% if menu_level == 0 %}
<ul{{ attributes.addClass('navbar-nav u-header__navbar-nav') }}>
{% else %}
<ul class="hs-sub-menu list-unstyled u-header__sub-menu u-header__sub-menu-offset animated">
{% endif %}
{% for item in items %}
{%
set classes = [
menu_level ? 'dropdown-item u-header__sub-menu-list-item' : 'nav-item u-header__nav-item',
item.is_expanded ? 'menu-item',
item.is_collapsed ? 'menu-item',
item.in_active_trail ? 'active',
item.below ? 'nav-item hs-has-sub-menu u-header__nav-item hs-sub-menu-opened',
]
%}
<li{{ item.attributes.addClass(classes) }} data-event="hover" data-animation-in="fadeInUp" data-animation-out="fadeOut">
{%
set link_classes = [
not menu_level ? 'nav-link u-header__nav-link',
item.in_active_trail ? 'active',
item.below ? 'nav-link u-header__nav-link',
item.url.getOption('attributes').class ? item.url.getOption('attributes').class | join(' '),
]
%}
{% if item.below %}
{{ link(item.title, item.url, {'class': link_classes, 'data-toggle': 'dropdown', 'aria-expanded': 'false', 'aria-haspopup': 'true' }) }}
{{ menus.menu_links(item.below, attributes, menu_level + 1) }}
{% else %}
{{ link(item.title, item.url, {'class': link_classes}) }}
{% endif %}
</li>
{% endfor %}
</ul>
{% endif %}
{% endmacro %}
I just need to give a class to {{ menus.menu_links(item.below, attributes, menu_level + 1) }} completely independent from its parents.
Is there a way to achieve it? My output is like this
Sublink
I need to change it like this
Sublink
If there's any other way to do so like with custom module or with hooks, please let me know

Why does this not work:
{% set relations = [{'cat':'friends','foo':'bar1'},{'cat':'enemies','foo':bar2},....] %}
{% set friends = [{'firstName':'John', 'lastName':'Goodman'},....] %}
{% set enemies = [{'firstName':'Ron', 'lastName':'Badguy'},....] %}
{% for relCat in relations %}
{% set list = relCat.cat %}
{% for person in list %}
{{ person.firstName }}
{% endfor %}
{% endfor %}
I admit that I 'm pretty new to twig, so I really searched and searched, but cannot find a solution for my problem (that I thought to be trivial) ....
I hope someone can help - I lost all my hair over this, thanks, Rudolph
Order of variables is important
So first: enemies and friends:
{% set friends = [{'firstName':'John', 'lastName':'Goodman'}] %}
{% set enemies = [{'firstName':'Ron', 'lastName':'Badguy'}] %}
Then set relations: again friends not 'friends', first is variable, second a string:
{% set relations = [{'cat':friends,'foo':'bar1'},{'cat':enemies,'foo':bar2}] %}
{% for relCat in relations %}
{% set list = relCat.cat %}
{% for person in list %}
{{ person.firstName }}
{% endfor %}
{% endfor %}
And this should work
See fiddle
You can also use the _context variable if you really need to keep strings:
{% set relations = [{'cat':'friends','foo':'bar1'},{'cat':'enemies','foo':bar2}] %}
{% set friends = [{'firstName':'John', 'lastName':'Goodman'}] %}
{% set enemies = [{'firstName':'Ron', 'lastName':'Badguy'}] %}
{% for relCat in relations %}
{% set list = _context[relCat.cat] %} {# <--- here #}
{% for person in list %}
{{ person.firstName }}
{% endfor %}
{% endfor %}
