Inside authControllers.js, I redirect to /signup page along with an error flash message
const err = validationResult(req);
//find errors and convert to array
const reqErrors = err.array();
const errors = reqErrors.filter(e => e.msg !== 'Invalid value');
let messages = [];
//loops through erros and push them into messages array
errors.forEach((error) => {
messages.push(error.msg);
});
//check if we have error or not
** if (messages.length > 0) {
// Store error into flash , so we display it later
req.flash('error', messages);
res.redirect('/signup');
}else{**
//move further
return next();
}
}
Inside userRoutes.js
userRouter.get('/',(req, res)=>{
console.log("hello from get route")
console.log(req.flash())
const errors = req.flash('error')
console.log(errors.length)
return res.render('signup',
{
title:"Chatting room Log in",
messages: errors,
// if error array > 0 then we have an error need to display
flag :errors.length > 0
}
);
});
When i run the program , this is following console.log(req.flash()) output:
{ error: [ 'Username is required and must be at least 5 characters.', 'Email is invalid', 'Password is required and must be at least 5 characters.' ] }
However, the variable errors is an empty array, thus when I tried to output errors.length. I got 0. It supposed to give me length 3.
Thanks for helping me! I am using connect-flash, passport.js , express.js.
