Receiving Object <IncomingMessage> has no method 'flash'

[joshbedo]

I was just going through the repo and recreating the setup for passport-local on one of my projects and when i go to my /login route i'm getting the message below. Inside of the cli i also get undefined for req.flash. Wondering if there is anything i'm missing. I did the following

1. Added connect-flash to the config.json
2. Installed the npm package connect-flash
3. Setup all the lib files exactly the same
4. Included the LocalStrategy within my login controller

controllers/login/index.js

'use strict';

var LoginModel = require('../../models/login');
var passport = require('passport');

module.exports = function(router) {
  var model = new LoginModel();

  router.get('/', function(req, res) {
    console.log(req.flash); // undefined
    model.messages = req.flash('error');
    res.render('login', model);
  });

  router.post('/', function(req, res) {
    console.log(req, res);

    passport.authenticate('local', {
      successRedirect: req.session.goingTo || '/',
      failureRedirect: '/login',
      failureFlash: true
    })(req, res);  // seems to be erroring here.
  });

};

At this point i've went through most of the files and can't seem to trace why the req object wouldn't include flash. Let me know if you need to see anything else specifically, Thanks!

What priority did you give it in config.json?

[joshbedo]

So i just solved this by changing spec.js to include flash like this. Not sure if this is needed? but it works.

// Used for serializing and deserializing passport users
'use strict';

var express = require('express');
var passport = require('passport');
var flash = require('connect-flash');
var auth = require('../lib/auth');
var userLib = require('./user')();
var db = require('../lib/database');
var crypto = require('../lib/crypto');

module.exports = function spec(app) {
  app.on('middleware:after:session', function configPassport(eventargs) {
    // Tell passport to use our newly created local strategy for authentication
    passport.use(auth.localStrategy());
    // Give passport a way to serialize and deserialize a user. In this case by the user's id.
    passport.serializeUser(userLib.serialize);
    passport.deserializeUser(userLib.deserialize);
    app.use(passport.initialize());
    app.use(passport.session());
    app.use(flash());
  });

  return {
    onconfig: function(config, next) {
      var dbConfig = config.get('databaseConfig')
      var cryptConfig = config.get('bcrypt');

      crypto.setCryptLevel(cryptConfig.difficulty);
      db.config(dbConfig);
      userLib.addUsers();
      next(null, config);
    }
  };
};

Also here is my config.json

    "express": {
      "view engine": "jsx",

    }

      }
    }

      }
    }

    // inject user into the response object

      "priority": 112,

      }
    }

    ,"middleware": {

        "static": {
            "module": {
                "arguments": [ "path:./.build" ]
            }
        }

        ,"router": {
            "module": {
                "arguments": [{ "directory": "path:./controllers" }]
            }
        }

    }
}

You'd have to put the flash in the middleware configuration rather than the root of the config.

[joshbedo]

Within spec.js? or which file?

[aredridel]

Within config.json.

Generally, kraken apps move as much middleware configuration as possible in there.

[joshbedo]

I do have flash set within the config.json though?

    // flash messaging middleware
    ,"flash": {
      "priority": 91,
      "enabled": true,
      "module": {
        "name": "connect-flash",
        "method": "flash"
      }
    }

[aredridel]

Yeah, outside the middleware configuration section. It won't do anything where you have it.

[joshbedo]

do'h i feel really dumb now, Thanks for the help!

[aredridel]

Sure thing! It takes a bit to get used to the json configs!
