Witam,
mam problem z zapisem do bazy danych zagnieżdżonego formularza z opcją checkboxes multiselect, natomiast produkt mi się zapisuje do bazy danych tabeli Product, a wartości z zagnieżdżonego formularza chciałbym zapisać do tabeli Link , proszę o pomoc, poniżej mój kod:
class Product < ActiveRecord::Base
has_many :links
has_many :categories, :through=> :links
accepts_nested_attributes_for :links, allow_destroy: true
end
class Category < ActiveRecord::Base
has_many :links
has_many :products, :through=> :links
accepts_nested_attributes_for :links
end
class Link < ActiveRecord::Base
belongs_to :product , :inverse_of => :links
belongs_to :category, :inverse_of => :links
end
views/new
<%= form_for (@product), url: {action: “create”} do |f| %>
<%= f.text_field :name %>
<%= f.text_area :description %>
<%= f.text_field :price %>
<% Category.all.each do |category|%>
<%= check_box_tag “f[category_ids][]”, category.id, f.object.categories.include?(category.id) %>
<%= category.name %>
<% end %>
<%= f.submit :submit %>
<%end%>
controller:
def create
@product = Product.new(product_params)
@product.save
redirect_to action: ‘index’
end
def product_params
params.require(:product).permit(:name, :description, :price, :links_ids=>[])
end
Na wyjściu dostaje coś takiego:
