This is by no means the final solution but it's a start in the right
direction. Eventually what needs to happen is we need to reduce the
complexity of the routing. CompsitionView can probably be removed later
on in favor of better Route objects. Also in the next version of sanic
we need to move merge_route and add_parameter out of the add_route logic
and just have them as standalone methods.
The tests should cover everything that we need so that if any changes
are made we can identify regression.
Addresses #353, now dynamic routes work alongside our newly minted
overloaded routes! Also fixed an unintended side effect where methods
were still being passed in as None for `Sanic.add_route`.
When user specifies HTTP methods to function handlers, it automatically
will be overloaded unless they duplicate.
Example:
# This is a new route. It works as before.
@app.route('/overload', methods=['GET'])
async def handler1(request):
return text('OK1')
# This is the exiting route but a new method. They are merged and
# work as combined. The route will serve all of GET, POST and PUT.
@app.route('/overload', methods=['POST', 'PUT'])
async def handler2(request):
return text('OK2')
# This is the existing route and PUT method is the duplicated method.
# It raises RouteExists.
@app.route('/overload', methods=['PUT', 'DELETE'])
async def handler3(request):
return text('Duplicated')
