I solved the ajax login the follwing way
controllers/user.py
def login():
'''
ajax login function
return login form error/success message and serialized user
as JSON object
'''
form = SQLFORM.factory(
Field('email', requires=[IS_EMAIL()]),
Field('password', 'password')
)
user = dict()
message = ''
success = None
if form.accepts(request.vars, session):
success = auth.login_bare(form.vars.email, form.vars.password)
if success:
from gluon.contrib import simplejson
if not auth.is_logged_in():
return simplejson.dumps({'id': None})
user = dict([(k, v)
for k, v in auth.user.iteritems() if k in 'first_name
last_name email id'.split()])
user['groups'] = [row.auth_group.role for row in db(db.
auth_membership.user_id == auth.user.id)(
db.auth_membership.group_id == db.auth_group.id).select()]
success = True;
else:
message = 'invalid login'
from gluon.contrib import simplejson
return simplejson.dumps({'user': user, 'form': str(form), 'message':message
, 'success': success})
in index.html
<div id="login-form"></div>
in my JavaScript lib
function trapForm(target, url, success_callback) {
$(target + ' form').submit(function(e) {
getForm(target, url, $(this).serialize(), success_callback);
e.preventDefault();
});
}
function getForm(target, url, fdata, success_callback) {
$.ajax({
url: url,
data: fdata,
method: 'post',
dataType: 'json',
success: function(data) {
if (data.message) {
$.jGrowl(data.message); // I juse jGrown instead of the build
in .flash
}
$(target).html(data.form)
trapForm(target, url, success_callback);
if (data.success == true) {
success_callback(data.user)
}
},
error: function() {
$.jGrowl('getForm failed');
}
});
}
/**
* get the login form via ajax and render it into the page
*/
function getLoginForm() {
// load login form
getForm('#login-form', localconfig.baseurl + '/user/login', undefined,
function(user) {
framework.this_user.update(user);// this is where I process the
returned result
... // further front end actions that should be done on login
follow here
});
}
Hope this helps other facing this problem.
