导轨从咖啡到控制器获取数据

Question

I have some controller code like this to update the workorder.wostatus_id field.

def changestatus
 @workorder = Workorder.find(params[:id])
 @workorder.update_attributes(params[:wostatus_id])
 render nothing: true
end

And the coffee script that ends up executing changestatus:

  receive: (event, ui) ->
    alert $(ui.item).attr('change_url')
    alert $(this).data('wostatus-id')
    $.ajax
      type: 'PUT'
      url: "http://localhost:5000/workorders/13/changestatus"
      data:
        wostatus_id: 3

I have hard coded the url and wostatus_id while trying to get this working.

But, the following line isn't getting the 3 from the coffee:

    @workorder.update_attributes(params[:wostatus_id])

If I hard code the line to this, it works to update the wostatus to 3:

@workorder.update_attribute :wostatus_id, '4'

Thanks in advance!

Answer 1

This bit of your CoffeeScript:

data:
  wostatus_id: 3

Should give you a params that looks like this:

{ :wostatus_id => 3 }

So when you say:

@workorder.update_attributes(params[:wostatus_id])

you're really saying:

@workorder.update_attributes(3)

and that doesn't really make much sense. You need to give update_attributes a key and a value:

@workorder.update_attributes(:wostatus_id => params[:wostatus_id])
