[SOLVED] GET() takes 1 positional argument but 2 were given

GET() takes 1 positional argument but 2 were given

I am new to web.py and I tried making a simple application where I retrieve a HTML file and display it.

Here is my complete code:

import web

render = web.template.render('templates/')

urls = (
    '/(.*)', 'index'
)

class index:
    def GET(self):
        return render.index()

if __name__ == "__main__":
    app = web.application(urls, globals())
    app.run()

When I run this, I get the error message:

<class 'TypeError'> at /

GET() takes 1 positional argument but 2 were given

Whenever I add a random parameter to the GET function, the page is able to function, but otherwise not. It would be great if someone could point out what is going wrong here.

Solution

(.*) will be used as second argument, change your code

class index:
    def GET(self, name):
        return render.index(name)

and template index.html

$def with (name)
<html>
<head>
    <title>Hello $name</title>
</head>
<body>
Hello $name
</body>
</html>
