Destroying model which matches input

So I have an email field in a model.

I would like a path in this model, where a field shows up in the view, and when I type an email address, and that address matches an existing model, it gets deleted. For unsubscribing from newsletter.

something like this:

newsletter_controller.rb

def unsubscribe(email)
  @newsletter = Newsletter.where(:email => email)
  @newsletter.destroy
end

in the view:

simple_form_for @newsletter do |f|
 f.input :email, method: delete
end

I got no idea how the view should work in the Rails Way.

In config/routes.rb, I suppose you have resources :newsletters Add a route for unsubscribe as following:

resources :newsletters do
   post 'unsubscribe', :on => :member
end

Check rake routes, you should have obtained a route path as unsubscribe_newsletter_path with POST verb.

Now, in your view: 

=form_for(:newsletter, :url => unsubscribe_newsletter_path) do |f|
   =f.label :email
   =f.text_field :email
   =f.submit "Unsubscribe"

(Change it as per syntax of simple_form)
Now, in newsletter_controller.rb(it should have been newsletter*s*_controller), add the method as:

def unsubscribe
  @newsletter = Newsletter.where(:email => params[:newsletter][:email])
  @newsletter.destroy if @newsletter
  redirect_to root_path
end

I hope it helps. Comment with places where it gives you error or doesn't work. I'll try to help.

Good luck. :)
