I'm Sreenesh, a beginner in Django web framework.
I've been facing some problems while doing a project.
this is my
OUTPUT of my django website which is not what i expected it to be.
this is my
HTML CODE from this I think you can say output is not the desired one.
command prompt throws me these 2 errors CMD PROMPT and I'm unable to fix these problems on my own as I'm a self learner.this is my bootstrap files directory as you can see the path I specified in link tag in my html code is right. this is my Settings.py and Url.py. Could anyone help me where i am doing wrong and how to fix these problems so I can get ahead with my project and learn some valuable lessons. Thank you everyone.
Update: this is my folder tree for those who need it for some verifications.
If you are facing some trouble wile using bootstrap in local then use CDN
in your base html file :
Into the <head> tag
<!-- Boostrap css -->
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap#4.6.0/dist/css/bootstrap.min.css"
integrity="sha384-B0vP5xmATw1+K9KRQjQERJvTumQW0nPEzvF6L/Z6nronJ3oUOFUFpCjEUQouq2+l" crossorigin="anonymous">
Just before closing the body tag
<!-- jQuery and Bootstrap js -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/bootstrap#4.6.0/dist/js/bootstrap.bundle.min.js"
integrity="sha384-Piv4xVNRyMGpqkS2by6br4gNJ7DXjqk09RmUpJ8jgGtD7zP9yug3goQfGII0yAns"
crossorigin="anonymous"></script>
Try it and let us know the result
You are getting a 404 error (does not exist) when it tries to load bootstrap.min.css. So, it's not in the folder specified by
{% static css/css/bootstrap.min.css %}
(or possibly, there's a file protection problem). Anyway, I think that translates to $BASE_DIR/static/css/css/bootstrap.min.css (using Linux notation, I don't do Windows).
Check that the file is there? And to debug in case I'm wrong, you can get the actual path it's looking for by using the same template tag to generate visible HTML content, or an HTML comment that you can see with your browser view page source
<!-- trying to load bootstrap from {% static css/css/bootstrap.min.css %} -->

I have installed the ember-remarkable addon in Ember 2.7. I am able to use the md-text component to format text content. The content adds the appropriate <code> markup for fenced code blocks such as:
```javascript
// An empty function
function test() {
}
```
However, the CSS to highlight that code as Javascript is not being included in my app. I am currently styling my app in app/styles/app.scss using the ember-cli-sass addon.
One way to include the CSS would be to add a <link> to app/index.html to a CDN such as:
<link rel="stylesheet" type="text/css" href="https://cdnjs.cloudflare.com/ajax/libs/highlight.js/9.5.0/styles/default.min.css">
Is that the best way? Or is there an "Ember" way to easily include the styles that are in the bower_components/highlightjs directory?
The proper way to include the Highlightjs CSS that I wanted is to add this line to ember-cli-build.js:
app.import('bower_components/highlightjs/styles/default.css');
Of course, this is not limited to the default style.
I have a section of my site in a subdirectory. My slicknav code works fine for any file in the main directory, hiding the regular navigation on small screens and displaying the hamburger menu icon instead. I assume I need to modify it to work correctly for a page in the subdirectory. I don't see how to do it.
designsondemand.com/about.htm works fine with this standard code:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<script src="jquery.slicknav.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$('#menu').slicknav();
});
</script>
But designsondemand.com/products/mugs.htm does not execute the code. I have set the link rel to reference the absolute file location, thinking that might be the problem.
<link rel="stylesheet" href="http://www.designsondemand.com/slicknavstyle.css">
<link rel="stylesheet" href="http://www.designsondemand.com/slicknav.css">
I would like to know if I can modify my JavaScript slicknav code to execute properly on a subdirectory, or if the only solution is to change my site's structure to do away with subdirectories.
Fresh night of sleep, new idea on Google search to answer my question. Today it was a search on "jquery on subdirectory." Answers seemed semi-relevant, and in the first one I got the answer although it took two tries. But SUCCESS!
The answer is to modify the script
<script src="jquery.slicknav.js"></script>
to instead include a leading slash to tell the page to find the code up one directory.
<script src="/jquery.slicknav.js"></script>
Up until recently I was including the file...
https://raw.githubusercontent.com/rwjblue/ember-qunit-builds/master/dist/globals/main.js
...in a 'TestRunner' page which I would open to run all of my Ember unit tests. All was great.
A few days ago, that file disappeared from github, so I started searching for the new way get my unit tests (e.g. moduleForComponent tests) running.
I first tried to simply include the ember-qunit.js file from the ember-qunit-builds repo, but errors like could not find module 'ember' came back.
Am I correct in saying that ember-qunit somehow depends on ember-test-helpers? I'm a bit lost as to which references I should be including before my test code...I have a feeling that I'm missing something related to ES6-style modules (export/import etc) with which I have little experience.
Could somebody perhaps point me in the right direction here? What should I be including on my 'TestRunner.html' page to get the 'moduleForComponent'-style tests happening again?
Note: I'm in a .NET environment where I understand that the frequently-mentioned tools for 'installing' this stuff (like Bower/npm) are not really available (are these a necessity for getting this to work?).
I'm not really sure where your problem is, but I can paste you relevant parts of my index.html (I'm using Ember App Kit here):
<!-- #if tests=true -->
<script src="/vendor/ember-shim.js"></script>
<link rel="stylesheet" href="/vendor/qunit/qunit/qunit.css">
<script src="/vendor/qunit/qunit/qunit.js"></script>
<script src="/vendor/qunit-shim.js"></script>
<script src="/vendor/ember-qunit/dist/named-amd/main.js"></script>
<div id="qunit"></div>
<!-- #endif -->
and
<!-- #if tests=true -->
<div id="qunit-fixture"></div>
<script src="/tests/tests.js"></script>
<script src="/tests/test-helper.js"></script>
<script src="/tests/test-loader.js"></script>
<script src="/testem.js"></script>
<!-- #endif -->
If you're looking particularly for the dist/globals/main.js file, then you can always go to github and select an older tag (not master), then go to the file's raw version. Here's the link to the 0.1.8 version:
https://raw.githubusercontent.com/rwjblue/ember-qunit/v0.1.8/dist/globals/main.js
If you want to stay up-to-date, use this repo:

Does this provide any help?
If this seems not-so-helpful (Noting the 'too localized' close votes), then please tell me why. I think Django and JQuery UI make a pretty good team so it's worth working out any gotchas about using them. The answer to this question is not something I've found documented or in another question and is relevant to use of other widgets in other places.
And on to the question...
I have a django project in development mode. Inside its static directory I have the following file structure:
directory: js
jquery-1.9.1.js
jquery-ui-1.10.1.custom.js
other_stuff.js
directory: css
directory: ui-lightness
directory: images
jquery-ui-1.10.1.custom.css
jquery-ui-1.10.1.custom.min.css
I'm trying to get the datepicker to work on one of my forms:
In my html head I have:
<link type="text/css" rel="stylesheet" href="/static/css/ui-lightness/jquery-ui-1.10.1.custom.css"/>
<script src="/static/js/jquery-1.9.1.js" type="text/javascript"></script>
<script src="/static/js/jquery-ui-1.10.1.custom.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function() {
$("#id_date_of_birth").datepicker();
});
</script>
And the input I am trying to change looks like:
<input type="text" size="10" id="id_date_of_birth" class="vDateField" value="1987-01-19" name="date_of_birth"/>
Now I know this question has been asked like a billion times before but none of the listed solutions I have read so far seem to work...Can anybody hazard a guess as to why I am getting the error$(...).datepicker is not a function ?
Stuff I've considered:
Everything seems to be included in the correct order. Other solutions mention including jquery ui's ...core.js but I think everything is included in jquery-ui-1.10.1.custom.js because otherwise the jquery ui download page is very misleading (I chose to download every component and there is no effect)
No other errors came up except the one I mentioned. All scripts loaded correctly
Nothing is included more than once
I'm waiting until the document is ready before calling anything at all so my problem is not due to bad timing
If the directory structure you listed is accurate, your jquery files do not end with ".js", while your references to those files do have ".js" in the page header. Add the ".js" extension to your jquery files and it should work.
you should also close your input element:
<input type="text" size="10" id="id_date_of_birth" class="vDateField" value="1987-01-19" name="date_of_birth" **/**>
For some reason the link wanted a separate closing tag...
<link type="text/css" rel="stylesheet" href="/static/css/ui-lightness/jquery-ui-1.10.1.custom.css"><link/>
This happened to me several times.
What i did was to copy the whole code (script) and placed it in the parent view.
If you're trying to place the script in a partial it may not work, try to put it in a higher level until you get the job done.
One example in django-oscar i had to place the script in the basket.html template to make it work in here:
{% include 'basket/partials/basket_content.html' %}
What’s the best way to keep related files together in Django?
In addition to our HTML templates, most views have at least one additional JavaScript file, and possibly an additional CSS file. For example:
item_detail.html
item_detail.js
item_detail.css
We want to keep these files side-by-side if possible, so we don't have to look in two or three directories to find them.
Update: I do know that it’s dumb to defeat caching and that’s not what I’m asking. Each page loads several JavaScript and CSS items that are properly cached. For example:
<!-- at top of file -->
<link rel="stylesheet" href="/master/css/site-main.css">
<!-- at bottom of file -->
<script type="text/javascript" src="/master/js/jquery.js"></script>
<script type="text/javascript" src="/master/js/site-main.js"></script>
That part is fine.
In addition to this, each page loads page-specific JavaScript and CSS:
<link rel="stylesheet" href="/static/css/widgets/item_detail.css">
<script type="text/javascript" src="/static/js/widgets/item_detail.js"></script>
In this example, item_detail.js would have event handlers that are needed on the item detail page (only).
Unfortunately this means that I now have several parallel directory structures for this view:
my_site
widgets
item_detail.html ← This is the view
static
css
item_detail.css ← This is the view-specific CSS
js
item_detail.js ← This is the view-specific JavaScript
What I want is this:
my_site
widgets
item_detail.html ← This is the view
item_detail.css ← This is the view-specific CSS
item_detail.js ← This is the view-specific JavaScript
Due to the way views work in Django, it’s not clear to me that this is possible.
If you are just organizing stuff for development, you can symlink you template dir with all template, css and js files to directory you are serving static files too.
So from your example: add my_site/widgets to Django TEMPLATE_DIRS config and cp -s my_site/widgets to directory you have your static files in.
This is dirty hack and, please, don't use it in production as it is very insecure IMHO. But if you want to have neatly organized project in development stage - then I see this as one possible solution.
And also consider that this might give you loads of headache when you move from development to production as stuff WILL fail.
I agree with freiksenet. A solution to the problem he adresses could be aggregating the various css and js files. The whole site then uses just one css and one js file. The first load would be higher, yes, but a big part of the speed of a site is in downloading files, and if caching is done right, aggregation of these files helps imho.
I unfortunately don't have an answer to your main question.
I keep javascript in files separated by function and combine them into a single minified js file with a pre-commit hook (right after the tests run).
for example: I have several jquery-ui dialogs on the site I'm currently working on. Each dialog's functionality is broken off into it's own js file for maintainability. And all the needed js files are "included" on the development pages using a short base.js file like so:
function include(filename) {
document.write(unescape("%3Cscript src='" + filename + "' type='text/javascript'%3E%3C/script%3E"));
}
// include-js (external)
include('/site_media/jquery-plugin1.js');
include('/site_media/js-sources/dialog1.js');
my pre-commit hook does a regex on this file...
include\('/site_media/(.*)'\);
and feeds all the files into YUI compressor.
So I guess the answer to your question is... I put them wherever makes sense to me logically, because on the live site, it'll all be in the minified JS file(s) anyway
You don't want to have your templates available as static files -- they may contain sensitive information or details about the page's implementation which are not appropriate for the public to see.
CSS and JS do not have to be segregated into separate directories -- simply place them in the static/ directory.
my_site/
widgets/
item_detail.html
static/
item_detail.css
item_detail.js
One approach I’m testing:
my_site/
widgets/
item_detail.html
item_detail.css
item_detail.js
These are not shared statically. Instead, in the HTML template:
<script type="text/javascript" charset="utf-8">
{% include "widgets/item_detail.js" %}
</script>
(Similar code for CSS.) I would only do this for page-specific JavaScript and CSS, not site-wide stuff that can benefit from caching.
This dumps the actual JavaScript and/or CSS right into the template, yet allows me to keep them in separate files for development purposes. This is nice, development-wise but defeats some JavaScript and CSS caching, but only for page-level stuff that’s not re-used on any other page.
