Why bootstrap doesn't work although I have loaded it, etc. (Django project)?

I'm working on this Django project. The functionality works perfectly fine. When I started working on the front-end using Bootstrap3, I ran into some issues (more like confusions).

First, I installed django-bootstrap3 using command prompt like so:

pip install django-bootstrap3

The installation was successful. Bootstrap3 was downloaded into this location in my computer c:\python34\lib\site-packages Then, I included it as a third-party app in settings.py in the list of INSTALLED_APPS in my main project directory like so:

 INSTALLED_APPS =(
--apps--
'bootstrap3',
)

Also in settings.py, I included jQuery like so:

BOOTSTRAP3 = {'include_jquery': True}

I modified my base.html to include the bootstrap elements. I have two apps, users and mynotess (sorry for bad naming)

base.html

EDIT: base.html is at the bottom of question.

For some reason, I loaded up localhost:8000 and it was still in the normal ugly HTML form. I checked online, and I found some CDN links and thought maybe if I just used the CDN links, it would work.

I then included this in base.html, copied right from Bootstrap's website.

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous">

(I included the links in the head section and the scripts in the body section of the HTML document).

It worked! However, when I removed the bootstrap3 from my INSTALLED_APPS and all the code that loads up bootstrap3 that was installed on my computer (such as {% load bootstrap3 %}, it didn't work. It went back to the ugly HTML format. Similarly, when I removed the CDN links and kept all the bootstrap3 code that loaded bootstrap installed on my computer, it went back to the ugly HTML format as well.

My question is:

The functionality of my Django website works just fine. Any help, explanations, or suggestions are greatly appreciated!

EDIT: base.html would have to be like this if I wanted the Bootstrap elements to show up.

If I removed just the CDN links, it wouldn't work. Similarly, if I removed just the template tags, it wouldn't work either.

It sounds like the Django for beginners book. If so be careful to check the folders in which you have placed your html files. I have fallen into this trap myself with this book. It isn't always clear in which directory they are creating new files. In my case, I only noticed this when my bootstrap wouldn't work on my /admin & change_password pages, but it was working fine for 'home'.

Besides the usual typo stuff (title tags etc.), you already defined to import bootstrap, but the jquery line doesn't get loaded until you actually stick the jquery into the parameter to utilise it. (I just realised this is quite old as the new one is already on Bootstrap 4).

You don't need to manually include any cdn links, your django bootstrap tags can handle that part of it for you unless you decide to change the links (in which case you'd write your change to the settings in the settings.py (assuming that's what you're using).

So...

Including the bootstrap CSS is this tag:

{% bootstrap_css %}

And for including the bootstrap javascript and jquery js files - instead of:

{% bootstrap_javascript %}

try using:

{% bootstrap_javascript jquery=True %}

or:

{% bootstrap_javascript jquery %}

if you have already defined jquery as True in your config

I had the same issue, and we both made the same typo: you forgot ">" in your closing title tag

Did you add the configurations in settings.py file? Please see this link https://django-bootstrap3.readthedocs.io/en/latest/settings.html

It sounds like {% boostrap_css %} is not pulling down the CSS. That would cause the issue you have described. You may want to update the settings so they are pulling from a CDN that you know works or just hard code them into your base template.

template.html

<!DOCTYPE html>
{# Load the tag library #}
{% load bootstrap3 %}
<html lang="en">
<head>
    <meta charset="utf-8"><!-- encoding characters -->
    <meta http-equiv="X-UA-Compatible" content="IE=edge"><!-- some Microsoft Edge/IE stuff -->
    <meta name="viewport" content="width=device-width, initial-scale=1"><!-- viewport -> the user's visible area of a webpage, -> this sets it to normal zoom (scale 1) and width of device -->
    <title>My Notes</title
    {# Load CSS and JavaScript #}
    {% bootstrap_css %}
    {% bootstrap_javascript %}
</head>

<body>    
{# Display a form #}
<form action="/url/to/submit/" method="post" class="form">
  {% csrf_token %}
  {% bootstrap_form my_form_here %}
  {% buttons %}
    <button type="submit" class="btn btn-primary">
      {% bootstrap_icon "star" %} Submit
    </button>
  {% endbuttons %}
</form>
</body>
</html>

settings.py

BOOTSTRAP3 = {
    'jquery_url': '//maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css'
    'base_url': '//maxcdn.bootstrapcdn.com/bootstrap/3.3.7/'
}
