When show
ing a resource using the Rails ActiveAdmin gem, I want to show a table of another associated model.
So let's say a Winery
has_many
:products
. Now I want to show the products associated on the show
page of the Winery
admin resource. And I want that to be a table similar to what I would get on the index
of the Products
resource.
I got it to work, but only by recreating the HTML structure manually, which kind of sucks. Is there a cleaner way to create an index
table style view for a specific subset of an associated resource?
What I have, which kinda sucks:
show title: :name do |winery|
attributes_table do
row :name
row(:region) { |o| o.region.name }
rows :primary_contact, :description
end
# This is the part that sucks.
div class: 'panel' do
h3 'Products'
div class: 'attributes_table' do
table do
tr do
th 'Name'
th 'Vintage'
th 'Varietal'
end
winery.products.each do |product|
tr do
td link_to product.name, admin_product_path(product)
td product.vintage
td product.varietal.name
end
end
end
end
end
end
To solve this problem, we used partials:
/app/admin/wineries.rb
ActiveAdmin.register Winery do
show title: :name do
render "show", context: self
end
end
app/admin/products.rb
ActiveAdmin.register Product do
belongs_to :winery
index do
render "index", context: self
end
end
/app/views/admin/wineries/_show.builder
context.instance_eval do
attributes_table do
row :name
row :region
row :primary_contact
end
render "admin/products/index", products: winery.products, context: self
active_admin_comments
end
/app/views/admin/products/_index.builder
context.instance_eval do
table_for(invoices, :sortable => true, :class => 'index_table') do
column :name
column :vintage
column :varietal
default_actions rescue nil # test for responds_to? does not work.
end
end
