I am using python web.py framework to create a small web application which
has just
1. Login screen (Authentication)
2. Screen with list of records(After succesfull login)
Presently i am trying to create a login screen authentication
I have created an `index.py` file with code as below
**index.py**
import os
import sys
import web
from web import form
from web.contrib.auth import DBAuth
render = web.template.render('templates/')
urls = (
'/', 'Login',
)
app = web.application(urls, globals())
db = web.database(dbn='mysql', db='Python_Web', user='root',
pw='redhat')
class Login:
login_form = form.Form(
form.Textbox('username', form.notnull),
form.Password('password', form.notnull),
form.Button('Login'),
)
def GET(self):
form = self.login_form()
return render.login(form)
def POST(self):
# if not self.login_form.validates():
# return render.login(self.login_form)
post = self.login_form()
username = post['username'].value
print username,">>>>>>>>>>>>>>>>>>>>>>username"
password = post['password'].value
ident = db.select('user', where='user_login=$username',
vars=locals())
if __name__ == "__main__":
web.internalerror = web.debugerror
app.run()
My **login.html** code
$def with (form)
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd";>
<html xmlns="http://www.w3.org/1999/xhtml"; lang="en" xml:lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Log in</title>
</head>
<body>
<div id="container">
<h1>Log in Details</h1>
<form action="" method="post" accept-charset="utf-8">
<p><label for="username">Username:
<input type="text" name="username" id="username" maxlength="254"
tabindex="1" />
</label></p>
<p><label for="password">Password:
<input type="password" name="password" id="password"
maxlength="254" tabindex="2" />
</label></p>
<p><label for="Login"></label><button id="Login"
name="Login">Login</button></p>
</form>
</div>
</body>
When i run the above file with url `www.localhost:9080` in browser i can
see the screen with fields `username, password and login` button , but when
i enter username and password and clicked `login` button and tried to
print the username i cannot fetch any data from the browser and the result
showing is as below
None >>>>>>>>>>>>>>>>>>>>>>username
0.0 (1): SELECT * FROM user WHERE user_login=NULL
Can anyone let me why i am unable fetch the details entered through browser
?, am i missing anything in the above code and finally all my intention is
to create a `login` page and `validate` the user details by checking in the
database
and `redirect` to the next page if user exits
I request to please help me out in writing the code for fetching the
details from the browser and checking in the database and redirecting to
another html page if user exists. I am really stuck and breaking my heads
to complete this process
