I have a blog application where I would like to display on the post view a
list of keyword categories and associated keyword types.
#views/post.html.erb
.
.
.
<% @post.keywords.group_by(&:keyword_category_id).each do |category, type|
%>
<li><%= category %></li>
<% type.each do |type| %>
<%= type.keyword_type_id %>
<% end %>
<% end %>
.
.
.
The keyword categories and keyword types are in separate models. The
association for the models are:
#keyword_category.rb
has_many :keyword_types
#keyword_type.rb
belongs_to :keyword_category
#post.rb
has_many :keywords
has_many :keyword_types, through: :keywords
has_many :keyword_categories, through: :keywords
I am using a join table called 'keywords', for keeping track of the keyword
categories and keyword types for a post.
The keywords table has the following fields.
post_id
keyword_category_id
keyword_type_id
The issue I am having is the view is displaying the ids and I can't figure
out how to do something like category.keyword_category.name? Any ideas on
what I am doing wrong? Thanks in advance for your help.
