I want have this ability to select multiple items with checkboxes and delete them in one place.
This is the code:
<% @products.each do |p| %>
<%= check_box_tag "product[]" , p.id %>
<div class="product_image">
<%= image_tag p.photo.url(:thumb) , :alt => "#{p.name}" %>
</div>
<%= link_to "<h3>#{p.name}</h3>" , edit_product_path(p) %>
<div class="product_desc">
<%=h truncate(p.description.gsub(/<.*?>/,''),80) %>
</div>
<div class="product_price">
<%=h p.price %>
</div>
<div class="product_categories">
<% for category in p.categories.find(:all) %>
<%=h category.name %>
<% end %>
</div>
<div id="produt_edit_nav">
<%= link_to 'Show' , product_path(p) %>
<%= link_to 'Edit', edit_product_path(p) %>
<%= link_to 'Remove', product_path(p), :confirm => "Are you really want to delete #{p.name} ?", :method => 'delete' %>
</div>
<% end %>
<div id="products_nav">
<%= link_to "Add a new Product" , new_product_path %>
</div>
The checkboxes give me right values, but:
How can I give them different id values for html code, all of them have id="product[]"
?
How can I delete the checked items in one click?
Also, what's the meaning of this part: product[]
?
1: You can create your own Ids by passing them as part of the options hash:
<%= check_box_tag "product_ids[]", product.id, false, :id => "product_#{product.id}" %>
For 2 and 3 I'd recommend looking at this Railscast.
