Add link to methods to array in controller - ruby-on-rails

Question

I have a index method in my rails 4 application controller that looks like:
def index
#products = Product.all
#headers = #products.map(&:data).flat_map(&:keys).uniq
#product_data = #products.map{ |product| product[ :data ].values }
end
So #product_data ends up with something like:
[["Table", "$199.99", "blue"], ["Book", "$9.99", "green"]]
In my view, I put all of this in a unordered list. But now I'd like to have a link_to an edit and delete page for each product. How can I include this in my array, so I can display a link for each product on the view page?

Answer 1

You could add product_id to the result of product[:data].values array. Then use that product_id as parameter to your product url_helpers.
#product_data = products.map{ |product| product[ :data ].values.unshift(product.id) }
This should give you something similar to:
[[1, "Table", "$199.99", "blue"], [2, "Book", "$9.99", "green"]]

Answer 2

I see there is no use of #product_data there.Why can't You display the data in a table in your index.html.erb and you can loop through every product,so that the edit and delete links appear to every product.Assuming that you have name,price and color attributes for your product model,just do like this
In your index.html.erb:
<table border=1>
<tr>
<th>Product Name</th>
<th>Product Price</th>
<th>Product Color</th>
<th></th>
<th></th>
</tr>
<% #products.each do |p| %>
<tr>
<td><%=p.name %></td>
<td><%=p.price %></td>
<td><%=p.color %></td>
<td><%=link_to 'Edit', :action => "edit", :id => p.id %></td>
<td><%=link_to 'Delete', :action => "delete", :id => p.id, :confirm => "Are you sure?" %></td>
</tr>
<% end %>
</table>
Note:
Its just an another approach.
