    <p>I am working on a really basic registration form in Node.js (with Express), and I am trying to find the easiest way to provide basic form validation. I've gone with "Express-Validator", which seems to do a fine job. However, my goal is to simply show any validation messages that are required and to <strong>leave the values entered by the user alone.</strong></p> <p>It seems that the request information is not making it back into the res.render, which I guess makes sense. However, I've looked everywhere I can think of and I can't find any reference that discusses how to keep form fields populated after showing error messages.</p> <p>Below is a small snippet describing my approach:</p> <pre><code>post: function(req, res){ var userName = req.body.username; var password = req.body.password; //Validate input req.assert("username", 'Invalid email address.').isEmail(); req.assert("password", 'Password cannot be empty.').notEmpty(); req.assert("passwordConfirm", 'Passwords entered do not match!').equals(password); //Make sure we have no validation errors var pageErrors = req.validationErrors(); if(!pageErrors) { userModel.CreateUser(userName, password, function(err){ if(err) { //there was a problem inserting new user... probably already exists //will need to check the error to confirm var dbErrorMessage = "Could not insert record into database!"; if(err.code === 11000) { //this is a duplicate entry dbErrorMessage = "A user with that email address already exists!"; } res.render('register.html', { pageErrors: [{msg: dbErrorMessage }]}); } else { res.render('register.html', { successMessage: successMessage }); } }); } else { res.render('register.html', { pageErrors: pageErrors }); } </code></pre>

    1. COThis is what people mean when they say that "the web is stateless". You need to manually re-populate your values after each request.

    2. COYeah, I realized it would require intervention from the server side to pass back the values, but I was hoping that express had something (or a middleware add-on) that might do this for us. I'll just go the AJAX form submission route. It'd make a better user experience anyway.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
