dutils is a small utility library that aims to provide JavaScript/Django developers with a few utilities that will help the development of RIA on top of a Django Backend.

It currently supports the following features:

• Reverse method for generating Django urls...

Try creating javascript helper functions (in django template) for generating url string. In simple form they could look like this:

function generete_some_url(id){
    return "{% url some_url itemid=112233 %}".replace("112233", id);
}

Maybe this has some other implications but I think it should work.

What s wrong with putting JavaScript in your templates?

You often want to call an initialisation function in your HTML template anyway, so why not pass it an object containing URLs you ll be using?

<script>
MYGLOBAL.mymodule.init({
    fancy_ajax_url:  {% url fancy %} ,
    fancier_ajax_url:  {% url fancier %} 
});
</script>

If you find yourself passing a lot of variable this way, or wanting to use logic in your JavaScript that you do in your HTML templates, then why not render your script through Django s templating engine? Remember, Django templates are not just for HTML documents - often it helps to use templates for plain text, XML, JSON, and yes even JavaScript. Worried about performance? Then cache the result.

I created a mechanism that builds a list of url patterns in your Django project and outputs that in a Javascript file. It is a fork of django-js-utils.

The repo link is here: https://github.com/Dimitri-Gnidash/django-js-utils

We created a small app called django-js-reverse for this purpose.

For example you can retrieve a named url

urls.py:

url(r ^/betterliving/(?P[-w]+)/(?Pd+)/$ , get_house , name= betterliving_get_house ),

in javascript like:

Urls.betterliving_get_house( house , 12)

result:

/betterliving/house/12/

What I usually do is put the URL in either an <input type="hidden" /> element, or in the rel="" attribute.

Then, when writing the JS (using jQuery below) I do:

$( div#show_more ).click(function () {
    var url = $(this).attr( rel );
    // or
    var url = $( #more_url ).val();

    $.get(url, function () { /* ... */ });
});

Nonstandard attributes are well supported by all major browsers and hidden elements don t have to be in forms.

First, you should name your url:

url(r ^blog/(?P<item_id>d+)/$ ,  blog.ajax.remove_item , name= blog-item ),

Then you could pass urls as variables to your module:

<script src="{{ STATIC_URL }}js/my-module.js"></script>
<script>
$(function(){
    MyModule.init( {% url blog-item item.id %} );
});
</script>

// js/my-module.js
var MyModule = {
    init: function(url) {
        console.log(url);
    }
};

You could use tokens in your url:

<script src="{{ STATIC_URL }}js/my-module.js"></script>
<script>
$(function(){
    MyModule.init("{% url blog-item item_id= 0000  %}");
});
</script>

// js/my-module.js
var MyModule = {
    init: function(url) {
        var id = 1;
        this._url = url;
        console.log(this.url(id));
    },
    url: function(id) {
        return this._url.replace( 0000 , id);
    }
};

Notice that your token should match the regex type to resolve successfully (I can t use {item_id} as token because it s defined with d+).

I was a little bit unsatisfied with this solution and I ended by writing my own application to handle javascript with django: django.js. With this application, I can do:

{% load js %}
{% django_js %}
{% js "js/my-module.js" %}

// js/my-module.js
var MyModule = {
    init: function() {
        var id = 1;
        console.log(Django.url( blog-item , id));
    }
};

$(function(){
    MyModule.init();
});

You can remove the parameters from the URL, and pass the dynamic parts as query parameters:

  $( #add-choice-button ).on( click , function () {
    var thing_id = $(this).closest( .thing ).attr( data-item-id );
    $.get( {% url  addThing  %}?t= +thing_id, function (data) {
      ...
    });
  });

I have found this cool django app called Django JS reverse

https://github.com/ierror/django-js-reverse

If you have a url like

url(r ^/betterliving/(?P<category_slug>[-w]+)/(?P<entry_pk>d+)/$ ,  get_house , name= betterliving_get_house ),

Then you do

Urls.betterliving_get_house( house , 12)

The result is

/betterliving/house/12/
