Here is my models:
class Item < ActiveRecord::Base
has_many :price_group_lines
has_many :price_groups, through: :price_group_lines
attr_accessible :item_name, :item_id
validates :item_name, presence: true
def to_label
"#{item_name}"
end
end
class PriceGroup < ActiveRecord::Base
has_many :customers
has_many :price_group_lines
has_many :items, through: :price_group_lines
attr_accessible :price_group_name
validates :price_group_name, presence: true
def to_label
"#{price_group_name}"
end
end
class PriceGroupLine < ActiveRecord::Base
belongs_to :item
belongs_to :price_group
attr_accessible :item_id, :price_group_id, :price, :item, :price_group
validates :price, :item_id, :price_group_id, presence: true
end
View (show.html.erb) for Price Group controller
<h1> PRICE GROUP </h1>
<p> <%= @pg.price_group_name %> </p> <br>
<% @pg.items.each do |i|%>
<%= i.item_name %>
<% end %>
<br>
<%= link_to "PRICE GROUP List", price_groups_path %>
So, I have the access to item_name in show.html.erb, but i don't know how to get the access to "price" attribute in PriceGroupLine model. Something, like i.items.price not working. Please, help!
Problem is because you have association of price, better said prices. Your variable i is already item just call price_group_lines on it and you will get association on which you can call each and get each price.
<% @pg.items.each do |i|%>
<%= i.item_name %> # will display item name
<% i.price_group_lines.each do |pgl| %>
<%= pgl.price %> # will display price
<% end %>
<% end %>
