Rails 4 Simple Form Validations - ruby-on-rails

Question

For some reason my validations aren't working correctly. I can submit the form if it's blank, and it gets processed by the controller. Isn't the point of the model to validate the params before it goes to the controller?
My Controller is:
class SubscribersController < ApplicationController
before_action :set_subscriber, only: [:show, :edit, :update]
# GET /subscribers
# GET /subscribers.json
def index
#subscribers = Subscriber.all
end
# GET /subscribers/1
# GET /subscribers/1.json
def show
# This is Wrong, but You Get The Idea
#subscriber = Subscriber.find_by(params[:id])
end
# GET /subscribers/new
def new
#subscriber = Subscriber.new
end
# GET /subscribers/1/edit
def edit
end
# POST /subscribers
# POST /subscribers.json
def create
#subscriber = Subscriber.new(subscriber_params)
respond_to do |format|
if #subscriber.save
format.html { redirect_to :back, notice: 'Thanks For Joining Our Mailing List!' }
format.json { render :back, status: :created, location: #subscriber }
else
format.html { redirect_to :back, notice: 'Error, Invalid Entry, or you are on the List Already!'}
format.json { redirect_to :back, #subscriber.errors, status: :unprocessable_entity }
end
end
end
# PATCH/PUT /subscribers/1
# PATCH/PUT /subscribers/1.json
def update
respond_to do |format|
if #subscriber.update(subscriber_params)
format.html { redirect_to :back, notice: 'Subscriber was successfully updated.' }
format.json { redirect_to :back, status: :ok }
else
format.html { redirect_to :back }
format.json { render json: #subscriber.errors, status: :unprocessable_entity }
end
end
end
# DELETE /subscribers/1
# DELETE /subscribers/1.json
def destroy
if #subscriber = Subscriber.find_by(params[:email])
respond_to do |format|
if #subscriber.destroy
format.html { redirect_to :back, notice: 'Subscriber was successfully destroyed.' }
format.json { head :no_content }
else
format.html { redirect_to :back, notice: 'Something Wrong' }
format.json { render json: #subscriber.errors, status: :unprocessable_entity }
end
end
else
redirect_to :back
flash[:error] = "Couldn't Find That Email Database!"
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_subscriber
#subscriber = Subscriber.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def subscriber_params
params.require(:subscriber).permit(:name, :email)
end
end
and my model is:
class Subscriber < ActiveRecord::Base
before_validation :downcase_email
validates_uniqueness_of :email
validates_format_of :email,:with => Devise::email_regexp
validates_presence_of :name, :message => "Name can't be blank"
validates_presence_of :email, :message => "Need an Email!!", on: :destroy
private
def downcase_email
self.email = self.email.downcase if self.email.present?
end
end
lastly my form:
<div class="five wide column subscriber">
<div class="ui inverted form segment">
<%= simple_form_for(#subscriber) do |f| %>
<%= f.error_notification %>
<h3 class="ui header">Join Our Mailing List</h3>
<div class="two fields">
<div class="field">
<%= f.input :name, placeholder: "Enter Name", required: true, error_html: { id: 'password_error'}%>
</div>
<div class="field">
<%= f.input :email, placeholder: "Enter Email", type: "email", required: true%>
</div>
</div>
<%= f.submit "Join", class: "ui blue submit button" %>
<% end %>
</div>
</div>
Let me know if I need to supply any more information. I hope this is an easy fix, but I'm not sure what I'm doing wrong.
