I want to provide csv links in a view and I placed the csv generating code in ApplicationHelper
. However I'm getting this error:
undefined method `send_data' for #<#<Class:0x0000010151c708>:0x0000010151a070>
referencing this:
send_data content, :type => "text/plain",
:filename => filename,
:disposition => 'attachment'
If I place the csv code in a controller it works fine. I was hoping to use the helper to avoid having to define routes for every controller I want to provide csv options for (I have a bunch). How can I make send_data
(and other necessary methods) available to the helper?
