Python Jinja2 loop index to make id unique - python

I'm using jinja2 template with Flask and MongoDB and I need to display users' cars in a template.
I was able to render cars in the profile template with car information and buttons to edit or delete a car. The problem is that if a user has multiple cars, only the first DELETE CAR button actually works (where I have an include modals to confirm) but nothing happens when click on the second or third delete button. Apparently I duplicated the id that needs to be unique. But I cannot achieve the results.
Here is my template: profile.html
{% extends 'layout/base.html' %}
{% block content %}
{% include 'components/navigation/navigation.html' %}
<div class="container">
<div class="row g-3 justify-content-center">
<div class="col-6 mt-5">
<div class="card">
<div class="card-body">
<h3 class="text-center profileHeader">
{{ username }}'s profile
</h3>
</div>
</div>
</div>
</div>
<div class="row row justify-content-center mt-4">
{% for car in cars %}
{% if session.user|lower == car.created_by|lower %}
<div class="card mb-3" style="max-width: 840px;">
<div class="row g-0">
<div class="col-md-4">
<img src="{{ car.car_image }}" class="imgCard" alt="ferrari image">
</div>
<div class="col-md-8">
<div class="card-body">
<ul class="list-group list-group-flush">
<li class="list-group-item"><strong>Year</strong>: {{ car.car_year }} </li>
<li class="list-group-item"><strong>Name</strong>: {{ car.car_name }}</li>
<li class="list-group-item"><strong>Designer</strong>: {{ car.car_design }}</li>
</ul>
<ul class="list-group list-group-flush">
<li class="list-group-item"><strong>Engine</strong>: {{ car.spec_engine }}</li>
<li class="list-group-item"><strong>Power</strong>: {{ car.car_power }}</li>
<li class="list-group-item"><strong>Trasmission</strong>: {{ car.trasmission }}</li>
<li class="list-group-item"><strong>Races</strong>: {{ car.races }}</li>
<li class="list-group-item"><strong>Wins</strong>: {{ car.wins }}</li>
<li class="list-group-item"><strong>Podiums</strong>: {{ car.podiums }}</li>
<li class="list-group-item"><strong>Poles</strong>: {{ car.poles }}</li>
<li class="list-group-item"><strong>Fast Laps</strong>: {{ car.fast_laps }}</li>
<li class="list-group-item"><strong>Constructor Championship</strong>: {{
car.constructor_champ
}}</li>
<li class="list-group-item"><strong>Driver Championship</strong>: {{ car.drivers_champ }}
</li>
<li class="list-group-item"><strong>Description</strong>: {{ car.description }}</li>
<p><em>by: {{ car.created_by }}</em></p>
</ul>
<div class="d-grid gap-2 d-md-flex justify-content-md-end">
<a id="myBtn" class="btn btn-danger"><i class=" fas fa-trash-alt"></i> Delete</a>
<a href="{{ url_for('editcar', car_id=car._id) }}" class="btn btn-danger" id="edit-btn"><i
class="far fa-edit"></i> Edit</a>
{% with car_id=car._id %}
{% include 'components/modals/confirm.html' %}
{% endwith %}
</div>
</div>
</div>
</div>
</div>
{% endif %}
{% endfor %}
</div>
enter code here
</div>
{% endblock %}

Just make unique the tag id of delete button, so the trigger will be unique in every button. How to make unique ? just add the car._id on tag id
<a id="myBtn-{{car._id}}" class="btn btn-danger"><i class=" fas fa-trash-alt"></i> Delete</a>

As #Darn pointed out, your ids need to be unique. But that is not the cause of your issue here.
I assume you have some Javascript code that gets triggered when user clicks on the delete link. The issue is probably from how that code is being triggered. The code needs to be written in such a way that it is bound to dynamically generated elements (you're generating the delete links on the fly i.e. afte the code for the delete was already bound; that delete code needs to also apply to each element when it is created).
You should bind the delete action to a class e.g.
$(".fa-trash-alt").on("click", function(){
$(this).parent() ...... // this is the link to the instance of the link that was clicked
});

collapsing accordion content in django for loop

I am trying to implement for loop in my accordion. Everything seems to be fine except the fact that when I click on 3rd or 4th button then other bodies stay expanded. It should work exactly the same as in the first example in Bootstrap documentation so if you click on Accordion Item #2 then Accordion Item #1 and Accordion Item #3 collapse.
I am sure that the issue is with my {% if forloop.first %} but I am not sure how can I dynamically change that so it will collapse all accordion contents except active one.
My code:
{% for category in top_categories %}
<div class="accordion" id="accordionExample">
<div class="accordion-item">
<h2 class="accordion-header" id="heading{{category.id}}">
<button class="accordion-button" type="button" data-bs-toggle="collapse"
data-bs-target="#collapse{{category.id}}" aria-expanded="false" aria-controls="collapse{{category.id}}">
{{category.title}}
</button>
</h2>
<div id="collapse{{category.id}}" class="accordion-collapse {% if forloop.first %} show {% else %} collapse {% endif %}" aria-labelledby="heading{{category.id}}"
data-bs-parent="#accordionExample">
<div class="accordion-body">
{% for qa in category.qa.all|slice:"0:3" %}
Q: {{qa}}<hr>
{% endfor %}
</div>
</div>
</div>
</div>
{% endfor %}
I think that the main problem is that you are including <div class"accordion" id="accordionExample"> inside the loop. A secondary one is that the "collapse" class is also necessary for the first iteration. Try this:
<div class="accordion" id="accordionExample">
{% for category in top_categories %}
<div class="accordion-item">
<h2 class="accordion-header" id="heading{{category.id}}">
<button class="accordion-button" type="button" data-bs-toggle="collapse" data-bs-target="#collapse{{category.id}}" aria-expanded="true" aria-controls="collapse{{category.id}}">
{{category.title}}
</button>
</h2>
<div id="collapse{{category.id}}" class="accordion-collapse collapse {% if forloop.first %}show{% endif %}" aria-labelledby="heading{{category.id}}" data-bs-parent="#accordionExample">
<div class="accordion-body">
{% for qa in category.qa.all|slice:"0:3" %}
Q: {{qa}}<hr>
{% endfor %}
</div>
</div>
</div>
{% endfor %}
</div>

What's problem with this pagination code?

This code already have done the pagination ,but it false because per page it shows all items in the database ,and the same in other pages
This is the routing
#app.route('/shop/page/<int:page_num>')
def shop(page_num):
products=Product.query.filter
(Product.category.has(Product.category_id))
shopPage=Product.query.paginate
(page=page_num,per_page=5,error_out=True)
return render_template('shop.html',
shopPage=shopPage,products=products)
And this is the HTML code of pagination and the output products of database
{% block content %}
<div class="mb-5">
{% for product in products %}
<div class="col-4 mt-3 ">
<div class="card">
<div class="card-header">
<form method="POST" action="{{ url_for('shop') }}" >
</form>
</div>
<div class="card-body">
<h5 class="card-title">{{product.name }}</h5>
<p class="card-text">
<div>Category: {{ product.category.name }}</div>
<div>Price: {{ product.price }} $</div>
<div>Company: {{ product.company }}</div>
</p>
</div>
</div>
</div>
{% endfor %}
</div>
{% for page in shopPage.iter_pages(left_edge=2, right_edge=2, left_current=1, right_current=2) %}
{% if page %}
<nav >
<ul class="pagination ">
<li class="page-item ">
<a class="page-link" href="{{url_for('shop',page_num=page)}}" tabindex="-1">{{ page }}</a>
</li>
</ul>
</nav>
{% else %}
...
{% endif %}
{% endfor %}

How do I hide or show content for each iteration?

I have a Lecture model which contains lectures. For each lecture I have a title and a content and eventually some files. I was trying to make that when somebody presses on a title, the title and the content will display under, but only for that lecture. Problem is that if I use a class, all lectures will be shown and if I use and id only the first one will be shown. How should I do this ?
$('#title').click(function () {
$('#lecture-hide').toggle();
});
{% for c in category.list %}
<div id="title">
<p>Lecture {{ forloop.counter }}: <span>{{ c.lecture_title }}</span>
</p>
<br>
</div>
<div id="lecture-hide" style="display: none;">
<br>
<li><h5>{{ c.lecture_title }}</h5></li>
<li><p>{{ c.content }}</p></li>
{% for file in c.files.all %}
{% if file.files %}
{% if forloop.first %}
<p id="files">Lecture files:</p>
{% endif %}
<li><a class="media"
href='{{ MEDIA_URL }}{{ file.files.url }}'><i
class="fas fa-download"></i>{{ file.files.name }}</a></li>
{% endif %}
{% endfor %}
<br>
</div>
{% endfor %}
Maybe you can use next selector in your jQuery code like this:
$('div.title').click(function () {
$(this).next().toggle();
});
You have to change id of the title to class to apply this to every element of the list.
You need to set dynamic attributes in your html:
{% for c in category.list %}
<div class="title" id="title-{{ c.id }}">
<!-- the content -->
</div>
<div class="lecture-hide" for="title-{{ c.id }}" style="display: none;">
<!-- the content -->
</div>
{% endfor %}
and in JQuery
$('.title').click(function () {
$('.lecture-hide[for="title-' + $(this).attr('id') + '"]').toggle();
});
This will works even if the html elements order change.

Django CMS: How to modify style of show_menu

I want to build a Django CMS template from a template found on https://startbootstrap.com.
I have load the following tags
{% load cms_tags menu_tags sekizai_tags staticfiles %}
and then within the <body> part the menu
...
<nav class="navbar navbar-expand-lg navbar-dark bg-dark fixed-top">
<div class="container">
<a class="navbar-brand" href="#">Start Bootstrap</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarResponsive">
<ul class="navbar-nav ml-auto">
{% show_menu 0 100 100 100 %}
</ul>
</div>
</div>
</nav>
...
Unfortunately, the links for the pages in the menu have almost no CSS (see image).
Basically, the links need to be of class nav-link. How can I fix this?
You can use a custom template for the menu tags;
<ul class="dropdown">
{% show_menu 1 100 100 100 "partials/navigation.html" %}
</ul>
Then in partials/navigation.html;
{% load cms_tags menu_tags cache cms_page %}
{% for child in children %}
<li class="nav-link">
{{ child.get_menu_title }}
{% if child.children %}
<ul class="sub_menu">
{% show_menu from_level to_level extra_inactive extra_active template '' '' child %}
</ul>
{% endif %}
</li>
{% endfor %}
<li class="nav-item">
<a class="nav-link" href="{{ child.attr.redirect_url|default:child.get_absolute_url }}">{{ child.get_menu_title }}</a>
{% if child.children %}
<ul class="sub_menu">
{% show_menu from_level to_level extra_inactive extra_active template '' '' child %}
</ul>
{% endif %}
</li>

Python Django Pagination + Bootstrap columns

Need recommendations or little help how to list insert in columns using Django built-in Pagination and Bootstrap.
For example. I have list with pagination. Every page have for example 9 results. But it all is in one column. I want to using Bootstrap row/column (col-md-4) to insert this list in 3 columns/3 rows. Is that with django Pagination possible or not? How? Or what you recommend?
This is my template code, where i make 3 columns with bootstrap. But all columns have 9 results and all column results are the same!
{% if project %}
<div class="container">
<div class="row">
<div class="col-md-4">
{% for projects in project %}
<li>
<a href="{{ current_page.get_absolute_url }}{{ project.slug }}">
<img src="{{ projects.main_image.image|thumbnail_url:'projects_top_thumbnail' }}" alt="{{ projects.title }}" />
<div class="showcase-title">
{{ projects.title }}
</div>
</a>
</li>
{% endfor %}
</div>
<div class="col-md-4">
{% for projects in project %}
<li>
<a href="{{ current_page.get_absolute_url }}{{ project.slug }}">
<img src="{{ projects.main_image.image|thumbnail_url:'projects_top_thumbnail' }}" alt="{{ projects.title }}" />
<div class="showcase-title">
{{ projects.title }}
</div>
</a>
</li>
{% endfor %}
</div>
<div class="col-md-4">
{% for projects in project %}
<li>
<a href="{{ current_page.get_absolute_url }}{{ project.slug }}">
<img src="{{ projects.main_image.image|thumbnail_url:'projects_top_thumbnail' }}" alt="{{ projects.title }}" />
<div class="showcase-title">
{{ projects.title }}
</div>
</a>
</li>
{% endfor %}
</div>
<div class="pagination">
<span class="step-links">
{% if project.has_previous %}
previous
{% endif %}
<span class="current">
Page {{ project.number }} of {{ project.paginator.num_pages }}.
</span>
{% if project.has_next %}
next
{% endif %}
</span>
</div>
</div>
</div>
{% endif %}
Try this
<div class="container">
<div class="row">
{% for projects in project %}
<div class="col-md-4">
<li>
<a href="{{ current_page.get_absolute_url }}{{ project.slug }}">
<img src="{{ projects.main_image.image|thumbnail_url:'projects_top_thumbnail' }}" alt="{{ projects.title }}" />
<div class="showcase-title">
{{ projects.title }}
</div>
</a>
</li>
</div>
{% endfor %}
</div>
<div class="pagination">
<span class="step-links">
{% if project.has_previous %}
previous
{% endif %}
<span class="current">
Page {{ project.number }} of {{ project.paginator.num_pages }}.
</span>
{% if project.has_next %}
next
{% endif %}
</span>
</div>
</div>
If you are looking for a grid of 3X3 Then the above code solves that.
