Twig Wordpress Repeater within a repeater

I would like to ask for help regarding a repeater within a repeater on Wordpress using Twig. The Services section shows up correctly but the Features section within the Services section isn't showing up.
Here is a screenshot of the Wordpress ACF.Click Me
And right below is the code that I am currently using.
Please advise. Thank you!
{% extends "page.twig" %}
{% block additional %}
<div id="page-services">
<section id="services">
<div class="row small-up-1 large-up-1">
<div class="small-12 medium-11 large-9 columns small-centered">
<div class="services-grid animated fadeIn wow">
<p align="center">
{{post.services_desc}}
</p>
</div>
</div>
</div>
<div class="line centered"></div>
</div>
<center>
<div class="row">
<div class="small-12 medium-11 large-9 columns small-centered">
<div class="features-header animated fadeIn wow">
{% for item in post.get_field('services_ist') %}
<div class="column services">
<h2 class="capitalize bold">
{{item.services_title}}
</h2>
{% if item.services_subtitle %}
<h4 class="subtitle">
{{item.services_subtitle}}
</h4>
<div class="line thin"></div>
{% endif %}
{% if item.services_content %}
<div class="description">
{{item.services_content}}
<br><br>
</div>
{% endif %}
{% if feats.services_feat %}
{% for feats in post.get_field('services_feat') %}
<p>{{feats.feat_title}}</p>
{% endfor %}
{% if feats.feats_desc %}
<h4 class="feats description">
{{feats.feats_desc}}
</h4>
{% endif %}
{% endif %}
</div>
{% endfor %}
</center>
</div>
</div>
</div>
</section>
</div>
{% endblock %}
As the ACF Integration Guide says, you shouldn’t use get_field() again when you try to access nested repeater fields:
When you run get_field on an outer ACF field, everything inside is ready to be traversed. You can refer to nested fields via item_outer.inner_repeater
So instead of using:
{% for feats in post.get_field('services_feat') %}
You should use:
{% if feats.services_feat %}
{% for feats in feats.services_feat %}
<p>{{ feats.feat_title }}</p>
{% endfor %}
{# … #}
{% endif %}
I have never done twig before but a quick search got me something.
Change the inner repeater to this:
{% for feats in services_ist.get_field('services_feat') %}
<p>{{feats.feat_title}}</p>
{% endfor %}
This way the second repeater knows that its a child from the first repeater instead of a direct child to the post.

How can I use loop functionality in twig template?

I want to use a looping functionality in region.html.twig file to I can
wrap elements that outputted from {{ content }} section.
Defult region.html.twig
{% if content %}
<div class="Parent">
{{ content }}
</div>
{% endif %}
The schematic generated Output:
<div class="Parent">
Item_1
Item_2
Item_3
</div>
I try to use below code to create a loop and add a wrapper around of each Item outputted from {{ content }}:
My code:
{% if content %}
<div class="Parent">
{% for item in items %}
<div class="child-wrapper">{{ item.content }}</div>
{% endfor %}
</div>
{% endif %}
The Final outpute that I want to achive:
<div class="Parent">
<div class="child-wrapper">Item_1</div>
<div class="child-wrapper">Item_2</div>
<div class="child-wrapper">Item_3</div>
</div>
If your data is: content = [1, 2, 3, ... , 100]
Then write
{% if content %}
<div class="Parent">
{% for item in content %}
<div class="child-wrapper">{{ item }}</div>
{% endfor %}
</div>
{% endif %}
If your data is array of assotiated arrays like this:
content = [
['content' => 1],
['content' => 2],
]
Then write
{% if content %}
<div class="Parent">
{% for item in content %}
<div class="child-wrapper">{{ item.content }}</div>
{% endfor %}
</div>
{% endif %}

symfony twig background image

I need to know why this script doesn't work with me and If anyone has a solution it will be appreciated.
My problem is that the image wouldn't be displayed background-image:url('{{asset('uploads/images/')}}{{image.name}}
<div class="carousel-inner">
{% set i = 0 %}
{% for project in projects %}
{% for image in project.images[:1] %}
{% if i == 0 %}
<div class="item active">
{% else %}
<div class="item">
{% endif %}
<div class="fill" style="background-image:url('{{asset('uploads/images/')}}{{image.name}}')"></div>
<div class="carousel-caption">
<h2>{{project.name}}</h2>
</div>
</div>
{% endfor %}
{% set i = i + 1 %}
{% endfor %}
</div>
</div>
You need to include your image.name inside of the asset() function.
{{asset('uploads/images/')}}{{image.name}} changed to
{{asset('uploads/images/' ~ image.name)}}

Twig batch with condition

I send Cards(some data) from controller to twig and create row with 3 elems.
{% for elem in Cards|batch(3) %}
<div>
<div class="row">
{% include ':appviews/elements/Card:Card.html.twig' with {'elem': elem} %}
</div>
</div>
{% endfor %}
It works well, but now i need to add card with static html (not from Data), that must be rendered one time.
Is there way, to add only 2 elems in row for the first loop?
{% for elem in Cards|batch(3) %}
<div>
<div class="row">
{% if loop.first %}
<div class="col-md-4 noPadding margin">
<div class="square"> SOME TEXT</div>
</div>
{% endif %}
{% include ':appviews/elements/Card:Card.html.twig' with {'elem': elem} %}
</div>
</div>
{% endfor %}
You cannot do this with "batch" filter. I suggest you use some logical tricks. There can be many of them, depending on:
how often do you want to insert the hardcoded block
how much code/template piece is being reused
For example, if you only need this once in the beginning, you can slice your array once, and then slice it again:
{% for elem in Cards|slice(0, 1) %}
<div>
<div class="row">
{% if loop.first %}
<div class="col-md-4 noPadding margin">
<div class="square"> SOME TEXT</div>
</div>
{% endif %}
{% include ':appviews/elements/Card:Card.html.twig' with {'elem': elem} %}
</div>
</div>
{% endfor %}
{% for elem in Cards|slice(2, Cards|length) %}
...
{% endfor %}
If you think there's too much copy/paste going on, you can create a macro for the "row", with some parameters and have all the logic in it. Then you can control, how, when and what is rendered. But this can be an overload in simple cases, so you decide:
http://twig.sensiolabs.org/doc/tags/macro.html
Well, final code is:
<div class="row rowQuest">
<div class="col-md-4 noPadding margin">
<div class="square">HARDCODED CARD</div>
</div>
{% set firstPartOfQuests = quests|slice(0,2) %}
{% for elem in firstPartOfQuests|batch(2) %}
{% include 'appviews/elements/questCard/questCard.html.twig' with {'elem': elem} %}
{% endfor %}
</div>
{% set lastPartOfQuests = quests|slice(2,quests|length) %}
{% for elem in lastPartOfQuests|batch(3) %}
<div class="row rowQuest">
{% include ':appviews/elements/questCard:questCard.html.twig' with {'elem': elem} %}
</div>
{% endfor %}
PS i still don't understand why i can't use for cycle without batch.
{% for elem in first2Quests %}
{% include 'appviews/elements/questCard/questCard.html.twig' with {'elem': elem} %}
{% endfor %}

How to handle twig view and bootstrap 3 rows/columns?

I have an Article entity and I made a findAll() in the controller.
I rendered each article in a div with the col-md-6 class.
But foreach 2 articles I must wrap these divs in a row div.
How can I do this with twig ?
Thanks.
EDIT :
I tried your code (NHG) like this:
{% for article in articles %}
{% if loop.index % 2 == 0 %}
<div class="row"></div>
{% endif %}
<div class="col-md-6">
<article class="well well-sm">
<img src="{{ article.image }}" alt="{{ article.title }}" class="img-thumbnail">
<h2 class="h3 text-center">{{ article.title }}</h2>
<div class="alert alert-success well-sm">
{{ article.content|striptags|slice(0, 235) }}...
</div>
<a class="btn btn-default btn-sm pull-right" href="#">{{ article.comments|length }} Comments</a>
<div class="btn-group btn-group-sm">
{% for tag in article.tags %}
<a class="btn btn-default">{{ tag.name }}</a>
{% endfor %}
</div>
</article>
</div>
{% endfor %}
But it doesn't work.
I want to have something like this :
<div class="row">
<div class="col-md-6"></div>
<div class="col-md-6"></div>
</div>
<div class="row">
<div class="col-md-6"></div>
<div class="col-md-6"></div>
</div>
<div class="row">
<div class="col-md-6"></div>
<div class="col-md-6"></div>
</div>
UPDATED:
As #Maerlyn suggested:
{% for row in articles|batch(2) %}
<div class="row">
{% for article in row %}
<div class="col-md-6">
// your content
</div>
{% endfor %}
</div>
{% endfor %}
OLD way:
Use loop.index (doc: The loop variable), modulo (doc: Math operators) and if (doc: if statement )
{% for article in articles %}
{% if loop.index % 2 == 1 %}
<div class="row">
{% endif %}
<div class="col-md-6">
// your content
</div>
{% if (loop.index % 2 == 0 or loop.last) %}
</div>
{% endif %}
{% endfor %}
{% for row in articles|batch(2) %}
<div class="row">
{% for article in row %}
<div class="col-md-6">
// your content
{% if loop.index is divisibleby(3) %}
</div>
{% endif %}
{% endfor %}
</div>
{% endfor %}
I suggest :
<div class="row">
{% for article in articles %}
{% if (loop.index0 % 2 == 0) and not loop.first %}
</div>
<div class="row">
{% endif %}
<div class="col-xs-12 col-sm-6 col-md-6 col-lg-6">
// your content
</div>
{% endfor %}
</div>
