I have changed my models after you pointed out they were wrong:
class Business < ActiveRecord::Base
belongs_to :address
has_many :types
has_many :categories, :through => :types
end
class Address < ActiveRecord::Base
has_many :businesses
end
class Category < ActiveRecord::Base
has_many :types
has_many :businesses, :through => :types
end
class Type < ActiveRecord::Base
belongs_to :business
belongs_to :category
end
I haven't entered the validation in yet, but I will do it later on.
My partial form looks like this:
<h1>New business</h1>
<%= error_messages_for :business %>
<% form_for(@business) do |f| %>
<p>
<b>Address</b><br />
<%= f.text_field :address_id %>
</p>
<p>
<b>Business name</b><br />
<%= f.text_field :business_name %>
</p>
<p>
<b>Business email</b><br />
<%= f.text_field :business_email %>
</p>
<p>
<b>Business telephone</b><br />
<%= f.text_field :business_telephone %>
</p>
<p>
<%= f.submit "Create" %>
</p>
<% end %>
<%= render :partial=>"new_address", :locals=>{:address=>Address.new}
%>
<%=
render :partial=>"new_category", :locals=>{:category=>Category.new} %>
<%= render :partial=>"new_type", :locals=>{:type=>Type.new} %>
<%= link_to 'Back', businesses_path %>
I've got rid of the multiple create buttons that were present when I
created the form and I am only left with one create button.
How do make the create button save all the data on the form? Also what
validation method do I use to check that the details I want to save
are not already present in the database?
