        * Graphical JSON-RPC browser and web console
        * Provides `system.describe`
        
        
        The basic API:
        
        **myproj/myapp/views.py**
        
            from django_jsonrpc import jsonrpc_method
        
            @jsonrpc_method('myapp.sayHello')
            def whats_the_time(request, name='Lester'):
              return "Hello %s" % name
        
            @jsonrpc_method('myapp.gimmeThat', authenticated=True)
            def something_special(request, secret_data):
              return {'sauce': ['authenticated', 'sauce']}
        
        
        **myproj/urls.py**
        
            from django.conf.urls.defaults import *
            from django_jsonrpc import jsonrpc_site
            import myproj.myapp.views # you must import the views that need connected
        
            urlpatterns = patterns('',
              url(r'^json/browse/', 'jsonrpc.views.browse', name="jsonrpc_browser"), # for the graphical browser/web console only, omissible
              url(r'^json/', jsonrpc_site.dispatch, name="jsonrpc_mountpoint"),
              (r'^json/(?P<method>[a-zA-Z0-9.]+)$', jsonrpc_site.dispatch) # for HTTP GET only, also omissible
            )
        
        
        **To test your service:**
        You can test your service using the provided graphical browser and console,
        available at http://YOUR_URL/json/browse/ (if using the url patterns from above) or with the included ServiceProxy:
        
            >>> from django_jsonrpc.proxy import ServiceProxy
        
            >>> s = ServiceProxy('http://localhost:8080/json/')
        
            >>> s.myapp.sayHello('Sam')
            {u'error': None, u'id': u'jsonrpc', u'result': u'Hello Sam'}
        
            >>> s.myapp.gimmeThat('username', 'password', 'test data')
            {u'error': None, u'id': u'jsonrpc', u'result': {u'sauce': [u'authenticated', u'sauce']}}
        
        We add the `jsonrpc_version` variable to the request object. It be either '1.0', '1.1' or '2.0'. Arg.
        
        Guide
        =====
        
        ### Adding JSON-RPC to your application
        
        #### 1. Install django-json-rpc
        
            git clone git://github.com/samuraisam/django-json-rpc.git
            cd django-json-rpc
            python setup.py install
        
            # Add 'jsonrpc' to your INSTALLED_APPS in your settings.py file
        
        #### 2. Write JSON-RPC methods
        
            from django_jsonrpc import jsonrpc_method
        
            @jsonrpc_method('app.register')
            def register_user(request, username, password):
              u = User.objects.create_user(username, 'internal@app.net', password)
              u.save()
              return u.__dict__
        
            @jsonrpc_method('app.change_password', authenticated=True)
            def change_password(request, new_password):
              request.user.set_password(new_password)
              request.user.save()
              return u.__dict__
        
        #### 3. Add the JSON-RPC mountpoint and import your views
        
            from django_jsonrpc import jsonrpc_site
            import app.views
        
            urlpatterns = patterns('',
              url(r'^json/$', jsonrpc_site.dispatch, name='jsonrpc_mountpoint'),
              # ... among your other URLs
            )
        
        
        ### The jsonrpc_method decorator
        Wraps a function turns it into a json-rpc method. Adds several attributes to the function speific to the JSON-RPC machinery and adds it to the default jsonrpc_site if one isn't provided. You must import the module containing these functions in your urls.py.
        
        `jsonrpc.jsonrpc_method(name, authenticated=False, safe=False, validate=False)`
        <ul>
        <li>
        `name`
        
        The name of your method. IE: `namespace.methodName`
        </li>
        <li>
        `authenticated=False`
        
        Adds `username` and `password` arguments to the beginning of your method if the user hasn't already been authenticated. These will be used to authenticate the user against `django.contrib.authenticate` If you use HTTP auth or other authentication middleware, `username` and `password` will not be added, and this method will only check against `request.user.is_authenticated`.
        
        You may pass a callablle to replace `django.contrib.auth.authenticate` as the authentication method. It must return either a User or `None` and take the keyword arguments `username` and `password`.
        </li>
        <li>
        `safe=False`
        
        Designates whether or not your method may be accessed by HTTP GET. By default this is turned off.
        </li>
        <li>
        `validate=False`
        
        Validates the arguments passed to your method based on type information provided in the signature. Supply type information by including types in your method declaration. Like so:
        
              @jsonrpc_method('myapp.specialSauce(Array, String)', validate=True)
              def special_sauce(self, ingredients, instructions):
                return SpecialSauce(ingredients, instructions)
        
        Calls to `myapp.specialSauce` will now check each arguments type before calling `special_sauce`, throwing an `InvalidParamsError` when it encounters a discrepancy. This can significantly reduce the amount of code required to write JSON-RPC services.
        
        *NOTE:* Type checking is only available on Python versions 2.6 or greater.
        </li>
        <li>
        `site=default_site`
        
        Defines which site the jsonrpc method will be added to. Can be any
        object that provides a `register(name, func)` method.
        </li>
        </ul>
        
        ### Using type checking on methods (Python 2.6 or greater)
        When writing web services you often end up manually checking the types of parameters passed. django-json-rpc provides a way to eliminate much of that code by specifying the types in your method signature. As specified in the JSON-RPC spec the available types are `Object Array Number Boolean String Nil ` and `Any` meaning any type.
        
              @jsonrpc_method('app.addStrings(arg1=String, arg2=String) -> String', validate=True)
              def add_strings(request, arg1, arg2):
                return arg1 + arg2
        
        However contrived this example, a lot of extra information about our function is available. The `system.describe` method will automatically be able to provide more information about the parameters and return type. Provide `validate=True` to the `jsonrpc_method` decorator and you can be guaranteed to receive two string objects when `add_strings` is called.
        
        **Note:** Return type information is used only for reference, return value types are not checked.
        
        Types can be specified a number of ways, the following are all equivalent:
        
              # using JSON types:
              @jsonrpc_method('app.findSelection(query=Object, limit=Number)')
        
              # using Python types:
              @jsonrpc_method('app.findSelection(query=dict, limit=int)')
        
              # with mixed keyword parameters
              @jsonrpc_method('app.findSelection(dict, limit=int)')
        
              # with no keyword parameters
              @jsonrpc_method('app.findSelection(dict, int)')
        
              # with a return value
              @jsonrpc_method('app.findSelection(dict, int) -> list')
        
        ### Using the browser
        To access the browser simply add another entry to your `urls.py` file, before the json dispatch one. Make sure to include the name attribute of each url.
        
            urlpatterns = patterns('',
              ...
              url(r'^json/browse/$', 'jsonrpc.views.browse', name='jsonrpc_browser')
              url(r'^json/', jsonrpc_site.dispatch, name="jsonrpc_mountpoint"),
              ...
            )
        
        
        ### Enabling HTTP-GET
        JSON-RPC 1.1 includes support for methods which are accessible by HTTP GET which it calls idempotent. Add the following to your `urls.py` file to set up the GET URL.
        
            urlpatterns += patterns('',
              (r'^json/(?P<method>[a-zA-Z0-9.-_]+)$', jsonrpc_site.dispatch),
            )
        
        Each method that you want to be accessible by HTTP GET must also be marked safe in the method decorator:
        
            @jsonrpc_method('app.trimTails(String)', safe=True)
            def trim_tails(request, arg1):
              return arg1[:5]
        
        You can then call the method by loading `/jsonrpc/app.trimTails?arg1=omgnowai`
        
        ### Using authentication on methods
        There is no specific support for authentication in the JSON-RPC spec beyond whatever authentication the transport offers. To restrict access to methods to registered users provide `authenticated=True` to the method decorator. Doing so will add two arguments to the beginning of your method signature, `username` and `password` (and always in that order). By default, the credentials are authenticated against the builtin `User` database but any method can be used.
        
            @jsonrpc_method('app.thupertheecrit', authenticated=True)
            def thupertheecrit(request, value):
              p = request.user.get_profile()
              p.theecrit = value
              p.save()
              return p.__dict__
        
        Using your own authentication method:
        
            def mah_authenticate(username, password):
              return CustomUserClass.authenticate(username, password)
        
            @jsonrpc_method('app.thupertheecrit', authenticated=mah_authenticate)
            def thupertheecrit(request, value):
              request.user.theecrit = value
              request.user.save()
              return request.user.__dict__
        
        In case authentication is handled before your method is called, like in some middleware, providing `authenticated=True` to the method decorator will only check that `request.user` is authenticated and won't add any parameters to the beginning of your method.
