I'm new to Jinja and this is my first post here on Stack Overflow.
I'm trying to loop through a gallery of images handled by bootstrap carousel/modal. I was able to let it work; <img> and <div> are rendered correctly, however I can't loop through the active element. Searching the web, I found that macros can help achieve it but I'm not familiar with using them. Here's the code I'm working on:
<div class="modal fade" id="myModalGal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-body">
<!-- Wrapper for slides -->
<div id="carousel-example-generic" class="carousel slide" data-ride="carousel">
<div class="carousel-inner">
<div class="item active">
{% for content in porte %}
{% if content.gal_porte %}
<img src="{{content.gal_porte}}" class="img-responsive" alt="test">
<div class="carousel-caption"></div>
</div>
<div class="item">
{% elif content.gal_porte %} <img src="{{content.gal_porte}}" class="img-responsive" alt="test1">
<div class="carousel-caption"></div>
{% endif %}
{% endfor %}
</div>
<!-- Controls -->
<a class="home-icon left" href="#carousel-example-generic" role="button" data-slide="prev"> <i class="fa fa-arrow-left"></i>
</a> <a class="home-icon right" href="#carousel-example-generic" role="button" data-slide="next"> <i class="fa fa-arrow-right" style="text-align: right;"></i>
</a>
</div>
</div>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Chiudi</button>
</div>
</div>
</div>
Jinja for loops have counters so you can check if you are on the first iteration of the loop and make that one the active slide.
Something like this:
<div class="carousel-inner">
{% for content in porte %}
<div class="item{% if loop.index == 1 %} active{% endif %}">
<img src="{{content.gal_porte}}" class="img-responsive" alt="test1">
<div class="carousel-caption"></div>
</div>
{% endfor %}
<!-- Controls -->
<a class="home-icon left" href="#carousel-example-generic" role="button" data-slide="prev">
<i class="fa fa-arrow-left"></i>
</a>
<a class="home-icon right" href="#carousel-example-generic" role="button" data-slide="next">
<i class="fa fa-arrow-right" style="text-align: right;"></i>
</a>
</div>

With the django framework I use a loop in my templates to display the image inside my database, I also use the Bootstrap grid to make it clean, but it not working correctly. As you can see the image on at the bottom are not align correctly.
hmtl
<div class="container">
<div class="row">
<div class="col-sm-12 col-md-3 col-lg-2">
<div class="card-filter" style="width: 10rem;">
<div class="card-header">
Pattern Type
</div>
<ul class="list-group list-group-flush">
{% for pattern in categories %}
<li class="list-group-item">{{pattern.name}}</li>
{% endfor %}
</ul>
</div>
</div>
{% for photo in photos %}
<div class="col-sm-12 col-md-5 col-ld-5">
<div class="card" style="width: 25rem;">
<img class="card-img-top" src="{{photo.image.url}}" alt="Card image cap">
<div class="card-body">
<p class="card-text">Symbol: GBPUSD<br>Pattern: ButterFly Bullish</p>
View Pattern
</div>
</div>
</div>
{% endfor %}
</div>
</div>
views.py
def home(request):
categories = Category.objects.all()
photos = Photo.objects.all()
context = {'categories': categories,
'photos': photos}
return render(request, "main/home.html", context)
You better put all the images in a parent that takes rest of the width after the list on the left, so it should be like this:
<div class="container">
<div class="row">
<div class="col-sm-12 col-md-3 col-lg-2">
<div class="card-filter" style="width: 10rem;">
<div class="card-header">
Pattern Type
</div>
<ul class="list-group list-group-flush">
{% for pattern in categories %}
<li class="list-group-item">{{pattern.name}}</li>
{% endfor %}
</ul>
</div>
</div>
<div class="col-sm-12 col-md-9 col-lg-10">
{% for photo in photos %}
<div class="col-sm-12 col-md-6">
<div class="card" style="width: 25rem;">
<img
class="card-img-top"
src="{{photo.image.url}}"
alt="Card image cap"
/>
<div class="card-body">
<p class="card-text">
Symbol: GBPUSD<br />Pattern: ButterFly Bullish
</p>
<a href="{% url 'photo' photo.id %}" class="btn btn-dark"
>View Pattern</a
>
</div>
</div>
</div>
{% endfor %}
</div>
</div>

I'm trying to create a social media news feed, with the posts, but I dont want to show the comments just if the user presses the button Show Comments. The problem is that when I press the button of one post, all the post will extend comments. I don't really know how to solve this...
{% for post in posts %}
<div class="container">
<div class="row">
<div class="[ col-xs-12 col-sm-offset-1 col-sm-5 ]">
<div class="[ panel panel-default ] panel-google-plus">
<div class="panel-heading">
<img class="[ img-circle pull-left ]" width="50" height="50" src="{{post.author.profile.image.url}}" alt="Mouse0270" />
<h3 class="author">{{post.author}}</h3>
<h5><span>Shared publicly</span> - <span> {{post.date_posted}} </span> </h5><br>
</div>
<div class="panel-body">
{% if user == post.author %}
<a class="text-right" href="{% url 'post-update' post.id %}"><p>Update</a>
<a class="text-danger text-right" href="{% url 'post-delete' post.id %}">Delete post</a>
{% endif %}
<p>{{post.content}}</p>
{% if post.image %}
<img src ="{{post.image.url}}" width="300" height="300" border="0" class="img-thumbnail">
{% endif %}
{% if post.video %}
<video width="250" controls >
<source src="{{post.video.url}}" type="video/mp4" >
</video>
{% endif %}
</div>
<br/>
<div class="container" >
<button class="btn btn-primary">Add comment</button>
</div>
<br>
<button type="button" class="btn btn-danger btn-block" data-toggle="collapse" data-target="#demo">See comments</button>
<div id="demo" class="collapse">
{% for comment in post.comments.all %}
<div class="container">
<div class="row">
<div class="col-sm-5">
<div class="panel panel-default">
<div class="panel-heading">
<strong>{{comment.author}}</strong> <span class="text-muted">commented at {{comment.created_on|date:"d M g:i a"}}</span>
</div>
<div class="panel-body">
<img class=" img-circle" width="30" height="30" src="{{comment.author.profile.image.url}}">
{{comment.body}}
</div><!-- /panel-body -->
</div><!-- /panel panel-default -->
</div><!-- /col-sm-5 -->
</div>
</div>
{% endfor %}
</div>
</div>
</div>
</div>
</div>
</div>
</div>
{% endfor %}
The problem is with the collapsable button above {% for comment in post.comments.all %}, but I dont know how to make it unique for every post.
I am trying to render the data from the database one by one by it does not work.
index.html
{% for i in edus %}
<div class="panel panel-default">
<div class="panel-heading" role="tab" id="headingOne">
<h4 class="panel-title">
<a data-toggle="collapse" data-parent="#accordion" href="#collapseOne" aria-expanded="true" aria-controls="collapseOne">{{i[0].title}}
</a>
</h4>
</div>
<div id="collapseOne" class="panel-collapse collapse in" role="tabpanel" aria-labelledby="headingOne">
<div class="panel-body">
<div class="row">
<div class="col-md-12">
<p>{{i[0].descripiton}} </p>
</div>
</div>
</div>
</div>
</div>
{% endfor %}
If you want to render specific index, you should change:
{{i[0].title}} into {{ i.0.title }}
{{i[0].descripiton }} into {{ i.0.description }}
I'm trying to make it like the following: https://getbootstrap.com/docs/4.3/examples/pricing/
it shows the screen divided into three section
so it should be like this I think...
<div class="row mb-2">
<div class="col-4 bg-danger">
.col-4
</div>
<div class="col-4 bg-warning">
.col-4
</div>
<div class="col-4 bg-success">
.col-4
</div>
</div>
But the problem is I am using django jinja template and for loop. so it groups the whole content.
This is my code but it won't do what's like in the link
<div class="row">
<div class="col-6 col-md-4">
<div class="card">
{% for all_episode in episode %}
<img class="card-img-top" src='{{all_episode.image.url}}'>
<div class="card-body">
<h5 class="card-title">
{{ all_episode.title }}
</h5>
<p class="card-text">{{ all_episode.story |slice:":100" }}...</p>
</div>
<div class="card-footer">
<small class="text-muted">
<span class="h5">
{{ all_episode.series }}
</span> /
<span class="h6">{{ all_episode.season }}</span></small>
</div>
{% endfor %}
</div>
</div>
Okay so I am creating an app which displays a picture with title and description. Here it is
{% block content %}
<!-- MODAL IMAGE - This is the preview -->
{% if projects %}
{% for project in projects %}
<div class="col-md-4 ">
<div class="grid mask">
<figure>
<img class="img-responsive" src="{{ project.preview.url }}" alt="">
<figcaption>
<h5>{{ project.title }}</h5>
<a data-toggle="modal" href="#modal1" class="btn btn-primary btn-lg">Take a Look</a>
</figcaption><!-- /figcaption -->
</figure><!-- /figure -->
</div><!-- /grid-mask -->
</div><!-- /col -->
<!-- MODAL DETAIL - This is suppos to show the details -->
<div class="modal fade" id="modal1" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title">{{ project.title }}</h4>
</div>
<div class="modal-body">
<p><img class="img-responsive" src="{{ project.preview.url }}" alt=""></p>
<p>Category: {{ project.category }}</p>
<p>Detail: {{ project.detail }}</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div><!-- /.modal-content -->
</div><!-- /.modal-dialog -->
</div><!-- /.modal -->
{% endfor %}
{% endif %}
{% endblock %}
So the app is working, when I add a new project image it shows the preview of all projects created. But when I click on the "Take a look" it does show the pop up window but the image and title always refer to the first image and title. IN SHORT MY MODAL DETAIL ALL REFER TO THE FIRST IMAGE AND TITLE.
Thank you.
eak,
You can have only one element with a given ID (modal1 in your case). All of your "Take a look" links open the first element with the modal1 ID, because the rest of the elements' IDs are disregarded. You need to render unique IDs for each project, e.g.:
...
<a data-toggle="modal" href="#modal{{ project.pk }}" class="btn btn-primary btn-lg">Take a Look</a>
...
<div class="modal fade" id="modal{{ project.pk }}" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
...
