Infinite edit_profile redirect

[paulsonak]

Thanks for the great tutorial!!

I'm working through chapter 6 and as far as I can tell, my code is the same as v0.6, but my packages may be newer (Flask 2.0.3, flask-wtf 0.15.1).

When I define the edit_profile route, I get an infinite redirect loop after clicking the 'edit profile' link. This additionally has the effect of deleting my username but not email from the database, which causes a bunch of other weird problems. But, if I switch the order of the if and elif statements so that it checks whether the request is a GET first, everything works again:

@app.route('/edit_profile', methods=['GET','POST'])
@login_required
def edit_profile():
    form=EditProfileForm()
    if request.method=='GET':
        form.username.data=current_user.username
        form.about_me.data=current_user.about_me
    elif form.validate_on_submit:
        current_user.username = form.username.data
        current_user.about_me = form.about_me.data
        db.session.commit()
        flash('Your changes have been saved.')
        return redirect(url_for('edit_profile'))
    return render_template('edit_profile.html', title='Edit Profile', form=form)

My conda env:

You are missing the parentheses aftervalidate_on_submit.
