ValueError [Solved]

I seem to be encountering an unexplaiable ValueError when I try to load any views with forms after making the post view/form/model. Here's my code

Post View

@app.route('/new_post', methods=('GET', 'POST'))
@login_required
def post():
    form = forms.PostForm()
    if form.validate_on_submit():
        models.Post.create(user=g.user._get_currnet_object(),
                          content=form.content.data.strip())
        flash("Message posted! Thanks!", "success")
        return redirect(url_for('index'))
    return render_template('post.html', form=form)

Post Form

@app.route('/new_post', methods=('GET', 'POST'))
@login_required
def post():
    form = forms.PostForm()
    if form.validate_on_submit():
        models.Post.create(user=g.user._get_currnet_object(),
                          content=form.content.data.strip())
        flash("Message posted! Thanks!", "success")
        return redirect(url_for('index'))
    return render_template('post.html', form=form)

Post Model 

class Post(Model):
    timestamp = DateTimeField(default=datetime.datetime.now)
    user = ForeignKeyField(
        rel_model = User,
        related_name = 'posts' )
    content = TextField()

    class Meta:
        database = DATABASE
        order_by = ('-timestamp',)

[MOD: Added python to markdown formatting -cf]

The Value error I'm getting displays the Message "builtins.ValueError

ValueError: too many values to unpack (expected 2)"

with two lines of code from my actual files quoted at the bottom:

File "/home/treehouse/workspace/templates/register.html", line 2, in <module>

{% from 'macros.html' import render_field %}

File "/home/treehouse/workspace/templates/layout.html", line 55, in <module>

{% for category, message in messages %}

Everything seems to work until I try to access /new_post, then every page with a form breaks.

I fixed it! It was indeed in layouts.html

on line 53 it should have been {% with messages = get_flashed_messages(with_categories=True) %} but I had True in all caps
