python-jsend 0.2.4

What is it?
============
a python jsend module.
compatable with jsend: http://labs.omniti.com/labs/jsend


Note:
============
(note: if there is a "README.rst" file, it's a softlink of "README")

Install:
============
pip install python-jsend

Or download the tarbal, decompress it, then run "python setup.py install"

Test:
==========
python setup.py test
note: it may show the warning messages like something below:

"test.pytest.py/_pytest.core:147: UserWarning: Module _pytest was already imported from test.pytest.py/_pytest, but /usr/local/lib/python2.6/dist-packages is being added to sys.path"

It does no harm, just ommit it.


Shortely: (borrowed from http://labs.omniti.com/labs/jsend)
=================================================================
"""
A basic JSend-compliant response is as simple as this:
{{{
{
status : "success",
data : {
"post" : { "id" : 1, "title" : "A blog post", "body" : "Some useful content" }
}
}
}}}

When setting up a JSON API, you'll have all kinds of different types of calls and responses. JSend separates responses into some basic types, and defines required and optional keys for each type:

||''Type''||''Description''||''Required Keys''||''Optional Keys''||
||success ||All went well, and (usually) some data was returned.||status, data||||
||fail ||There was a problem with the data submitted, or some pre-condition of the API call wasn't satisfied||status, data||||
||error ||An error occurred in processing the request, i.e. an exception was thrown||status, message||code, data||



| ''Type'' | ''Description'' | ''Required Keys'' | ''Optional Keys'' |
|----------+--------------------------------------------------------+-------------------+-------------------|
| success | All went well, and (usually) some data was returned. | status, data | |
| | | | |
| fail | There was a problem with the data submitted, | status, data | |
| | or some pre-condition of the API call wasn't satisfied | | |
| | | | |
| error | An error occurred in processing the request, | status, message | code, data |
| | i.e. an exception was thrown | | |

RError --> Result Error
