WSGI middleware that does Rails style PUT and DELETE request emulation.
The middleware intercepts the wrapped application's response and looks
for forms with method="PUT" or method="DELETE". For each such form
it replaces the value of method with "POST" and adds a hidden input
field _method that contains the original request method.
It also intercepts incoming requests and does the inverse transformation.
What this all means is that you can use PUT and DELETE forms in your HTML code, without having to worry about browser support for these request methods.
You can install EmulateRest from PyPI:
easy_install emulaterest
or you can install the latest version from the github repository:
git clone git://github.com/abiczo/emulaterest.git cd emulaterest python setup.py install
- For
text/htmldocuments the default behavior is to inject HTML style<input>elements. You can tell EmulateRest to inject XHTML style<input/>elements either by using theforce_xhtmloption or by serving your documents asapplication/xhtml+xml. - If you are using a gzipping middleware or any other middleware that modifies the content-encoding, make sure that EmulateRest is wrapped in that middleware and not the other way round.
A complete working example using web.py:
import web
urls = ('/', 'index')
class index:
def GET(self):
web.ctx['headers'].append(('Content-Type', 'text/html'))
return """<html><head><title>PUT test</title></head><body><div>
<form method="PUT" action="/">
<div>
<input type="text" name="inp" value="value">
<input type="submit" value="Submit">
</div>
</form>
</div></body></html>
"""
def PUT(self):
return 'PUT ' + str(web.input())
if __name__ == '__main__':
import emulaterest
app = web.application(urls, globals())
app.run(emulaterest.EmulateRestMiddleware)
