Question

I have A method for format the output as JSON.
My keyword_filter will be pass in this this format:

<QueryDict: {u'customer_type': [u'ABC'], u'tag': [u'2']}>
<QueryDict: {u'customer_type': [u'TDO'], u'tag': [u'3']}>
<QueryDict: {u'customer_type': [u'FRI'], u'tag': [u'2,3']}>

In fact this I got from request.GET (keyword_filter=request.GET)

This is my method: (I am trying)

 def save_fiter_to_JSON(self, dest, keyword_filter):
    fwrite  = open(dest, 'a')
    #keyword_filter = <QueryDict: {u'customer_type': [u'FRI'], u'tag': [u'2,3']}>
    string_input1 =string.replace(str(keyword_filter), '<QueryDict:', '["name:"')
    string_input2 = string.replace(string_input1, '>', '')
    fwrite.write(string_input2+",\n")
    fwrite.close()

The JSON format that I want:

[
 {"name": filter_name, "customer_type": "ABC", "tag": [2,3]},
]

Or the other good one format from you.

import simplejson as json
>>> json.dumps(['foo', {'bar': ('baz', None, 1.0, 2)}])
'["foo", {"bar": ["baz", null, 1.0, 2]}]'

filter_name will be passed from the method save_fiter_to_JSON.

Some tips:

• you can convert django’s QueryDict to to Python dictionary with dict(keyword_filter) expression,
• you can add additional record to the dictionary with dict(keyword_filter, name=filter_name) expression.

Then use json module to dump JSON and write it to the file.
