Passing objects from Django to Javascript DOM

Question

I\'m trying to pass a Query Set from Django to a template with javascript.

I\'ve tried different approaches to solve this:

1. Normal Approach - Javas

Answer 1

Ok, I found the solution!

Mostly it was because of not quoting the results. When Javascript was trying to parse the object this wasn't recognized as string.

So, first step is:

var js_list = {{django_list}}; 

changed to:

var js_list = "{{django_list}}";

After this I realized that Django was escaping characters so I had to replace them like this:

 var myJSONList = (("{{json_list}}").replace(/&(l|g|quo)t;/g, function(a,b){
                return {
                    l   : '<',
                    g   : '>',
                    quo : '"'
                }[b];
            }));

 myData = JSON.parse( myJSONList );

Note: I tried to avoid escaping characters from Django using this:

var js_list = "{{json_list|safe}}"; 

But this doesn't work because it gets confused with the quotes.

Finally I found a way to avoid the logic on the backend of converting to JSON before sending it to Javascript:

var myDjangoList = (("{{django_list |safe}}").replace(/&(l|g|quo)t;/g, function(a,b){
            return {
                l   : '<',
                g   : '>',
                quo : '"'
            }[b];
        }));

myDjangoList = myDjangoList.replace(/u'/g, '\'')
myDjangoList = myDjangoList.replace(/'/g, '\"')

myData = JSON.parse( myDjangoList );

I'm sure this can be improved, I let this to you ;)
