ruby on rails - How to submit a form and delete a post -

i have 2 models in rails project: link , campaign. in show.html.erb link have form create new campaign looks this

 <%= form_for :campaign, url: campaigns_path |f| %>    <%= f.hidden_field :name, value: current_user.email %>    <%= f.hidden_field :product, value: @link.product %>    <%= f.hidden_field :title, value: @link.title %>    <%= f.hidden_field :website, value: current_user.website %>    <%= f.hidden_field :productlink, value: @link.url %>    <%= f.hidden_field :description, value: @link.description %>    <%= f.hidden_field :date, value: date.today.to_s %>    <br>    <br>    <%= f.submit :"let's go make money", class: "btn btn-primary" %>  <% end %> 

this works. problem deleting post link while creating new post based on campaign. basically, want submit form , delete else.

you pass id of link want destroy in form_for:

  <%= form_for @campaign, :url => { :controller => :campaign, :action=>:create, :link_id => @link.id } |f| %>     <%= f.hidden_field :name, value: current_user.email %>    <%= f.hidden_field :product, value: @link.product %>    <%= f.hidden_field :title, value: @link.title %>    <%= f.hidden_field :website, value: current_user.website %>    <%= f.hidden_field :productlink, value: @link.url %>    <%= f.hidden_field :description, value: @link.description %>    <%= f.hidden_field :date, value: date.today.to_s %>    <br>    <br>    <%= f.submit :"let's go make money", class: "btn btn-primary" %>  <% end %> 

in links_controller.rb:

 def show       @campaign = campaign.new     end 

and in campaigns_controller.rb: def show @ end

def create   @link = link.find(params[:link_id])   @link.destroy   ...   # create campaign end
