ReferenceError: User is not defined

[tdesaules]

Hi guys,

I test the most simple :

passport.use(new WindowsStrategy({
integrated: true
}, function(profile, done){
User.findOrCreate({ waId: profile.id }, function (err, user) {
done(err, user);
});
}));

app.get('/windows',
passport.authenticate('WindowsAuthentication'),
function (req, res){
res.redirect('/foo/bar');
});

But I always get :
ReferenceError: User is not defined

Any idea ?

Any updates on this? I'm getting the same.

Turns out User.* is just an example of user code, it's not anything included by this module.

[GeorgeChen1982]

yes, I am facing the same situation, what should I do?

[GeorgeChen1982]

I have figured out what went wrong. 'User' is a something like database or a object mapper and is not provided by passport module. Actually, you don't need it.
I replace the snippet just like the following:

old:

User.findOrCreate({ waId: profile.id }, function (err, user) {
done(err, user);
});

new:

if (profile) {
user = profile;
return done(null, user);
}
else {
return done(null, false);
}

still it doesnt work!!!!

Seems like User should be defined as a sequelize instance

[yogeshrathod2508]

• const User=require('../models/User')

• User.find()
  .then((user) => res.json(user),{currPage:"Users"})
  .catch((err) => res.status(400).json("Error is " + err),{currPage:"Users"})

From both points we can see that the variable to require the model file should be used in find() method
This solved my problem. Hope it solves yours

still it doesnt work!!!!

add this serializer if you are not getting the error - "Failed to serialize user into session"

passport.serializeUser(function(user, done) {
done(null, user.id);
});

@raginiagrawal02 I have that and my code is not working. But, I also have the following:
passport.deserializeUser(function(user, done){ User.findById(id, function(err, user) { done(err, user); }); });

[formulaRoot]

Nevermind, solved it!

[spydaspider]

How did you solve it

[sandhyapatel12]

const User = require('../models/User')

import this line and solve your error
