Question

I’m new to rails, ruby, and web development in general, and I’m having trouble trying to remove an object from my database.

I get “1 error prohibited this debate from being saved: Proposition can’t be blank”

when I call the destroy method of the object.

This is my link:

<%= link_to 'Delete this debate', debates_path, :method => :delete %>

and this is my destroy method:

def destroy
  Debate.find(params[:id]).destroy

  respond_to do |format|
    format.html { redirect_to(debates_path) }
    format.xml  { head :ok }
  end
end

If the debate is being destroyed anyway, why do I still get an error when the proposition is blank?

Edit:

The model for the debate:

class Debate < ActiveRecord::Base
   validates :proposition, :presence => true

   has_many :responses, :dependent => :destroy
end

I’m following the tutorial from here: http://guides.rubyonrails.org/getting_started.html

Answer 1

Or just:

<%= link_to 'Delete this debate', debate, :method => :delete %>
