A small snippet of code I've written that is ready for production. Super simple, straight forward login process. Written as an alternative to signing up/in with twitter. Tech: Python, Flask, Jinja

view-login.py

@blueprint.route('/register', methods=['GET','POST'])
def register():
  if request.method == 'GET':
    return render_template('influencer/register.jt')
  data = request.form.to_dict()
  # pass data to validation lib to be validated
  result = v.influencer_register(data)
  if result.is_valid():
    #check for duplicate
    active_influencer = get_influencer_by_email(result.get_value('email'))
    
    if not active_influencer:
      i = create_influencer(**result.get_valid())
      g.s.add(i)
      flash('Success!')
      return redirect(url_for('.signin_email'))
  
  flash('That email address already exists')
  return redirect(url_for('.signin_email'))
  
flash('Something went wrong')
return redirect(url_for('.register'))

@blueprint.route('/signin/email', methods=['GET', 'POST'])
def signin_email():
  if request.method == 'GET':
    return render_template('influencer/signin.jt')
    
  data = request.form.to_dict()
  # pass to validation lib to be validated
  result = v.influencer_register(data)
  if result.is_valid():
    # check for existing
    active_influencer = get_influencer_by_email(result.get_value('email'))
    
    if active_influencer:
      h.login_influencer(active_influencer)
      flash('login success!')
      return h.redirect_home()
      
    flash('That user does not exist')
    return redirect(url_for('.signin_email'))
