Hi, ALL,
I'd like someone to help me understand this situation.
Looking at the page: https://docs.djangoproject.com/en/dev/topics/serialization/ the part which says "Serialization formats->JSON" there is an example of how the data would be serialized.
The sample uses the symbol "double quotation".
On my machine I have django 1.6.1:
C:\Documents and Settings\Igor.FORDANWORK>python
Python 2.7.5 (default, May 15 2013, 22:43:36) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import django
>>> django.get_version()
'1.6.1'
>>>
In my views.py I'm using following code:
usb_list = serializers.serialize("json", USB.objects.all())
return render_to_response('html/index.html', {"usb_data": usb_list} )
return render_to_response('html/index.html', {"usb_data": usb_list} )
where USB is the data model class.
This class overrides a __unicode__() function to produce a good output on the console.
Now when I go to the page to see it in the browser I see the data as a JSON but the data is surrounded with a text """.
So in the docs I see something like this: "abc", while my application will show: "abc"
In the index.html I have this code:
<!DOCTYPE html>
<html>
<head>
<title>Test</title>
{% load staticfiles %}
<script type="text/javascript">
var data = "{{usb_data}}";
<html>
<head>
<title>Test</title>
{% load staticfiles %}
<script type="text/javascript">
var data = "{{usb_data}}";
# some more JavaScript code
</script>
</script>
<html>
</html>
Is this a recent change? Am I doing something wrong?
Thank you.

In your template try {{usb_data|safe}}

.......because django escapes everything in the template by default except you ask not to. One of the methods of doing so if by using the `safe` filter like Mario suggested.
You can read the documentation on how to escape or unescape stuff in your template.

Thank you, guys. It works.
Now I need to figure out why I still don't see my data in the jQWidget
control (jqxGrid)...
Anybody familiar with this library?
Thank you.

Thats probably because you are returning the json as a context in a response with the default "text/html" mime type. Your response should have mime type as " application/javascript".
Your json data should be in the response

How do I do that? Could you give me some code, please?
Or at least point to the docs...
Thank you.

Hi
IANA says the JSON mime type be application/json, so you might want to use that.
application/javascript should be for javascript.
