Question

I have problem with rails routing.

Error is:

No route matches {:controller=>"orders", :action=>"sell_item"}

Route rule looks like:

match 'orders/sell/:id' => 'orders#sell_item', as: 'sell_item'

link generation in the view file:

<%= link_to 'sell', sell_item_url, id: line_item.id %>

function in the OrdersController

def sell_item(line_item_id)
  line_item = LineItem.find(line_item_id)
  line_item.status = 1
  line_item.save
end

It still generates route if I remove ‘/:id’ from route and ‘,id: line_item.id’ from link_to.

Answer 1

Instead of

<%= link_to 'sell', sell_item_url, id: line_item.id %>

try

<%= link_to 'sell', sell_item_url(line_item) %>

Rails should build the route for you based on the object.
