Flask - Build a Social Network - Form validation is not working.

Here is a link to a snapshot of my workspace: https://w.trhou.se/uwrdy4qmdj

I'm running into some issues with the form validation. When I leave the fields blank and click submit, it should tell me that the data is required, but it's not. I've gone over my code several times and I'm not seeing anything wrong with it. Thoughts?

Do you have a form that's missing method="POST"?

That was it! On the register.html file, I was missing the = between method and "POST". Thanks!

I don't see anything obviously wrong either.

If you put a pdb into your view right before the form.validate_on_submit(), after a post, does anything show in, I think, form.errors?

Thanks for looking at this Kenneth. Perhaps I'm doing this wrong, but the page won't load with a 502 -Bad Gateway error when I try and insert pdb.

Am I doing this right? 

@app.route('/register', methods=('GET', 'POST'))
def register():
    form = forms.RegisterForm()
    import pdb
    pdb.set_trace()
    if form.validate_on_submit():
        flash("Yay, you registered!", "success")
        models.User.create_user(
            username=form.username.data,
            email=form.email.data,
            password=form.password.data
        )
        return redirect(url_for('index'))
    return render_template('register.html', form=form)

So I spent some more time on this today. I downloaded a copy of your files and compared it line by line to what I had and I didn't see anything different. Next, I tried copying my code into a brand new workspace and it did the same thing.

One thing I have noticed is that it is putting the csrf_token in my URL and also in the console ever time I press the button, which seems odd. The working code I downloaded from the video and then copied into workspaces doesn't seem to do this. Thoughts?
