Rails 5: error passing time_ago_in_words from controller to view
up vote

favorite
I want to prevent users from deleting comments that are more than X minutes old. (This is determined by a status field.) I anticipate that the value of X may change in future so it's currently defined in an initializer:
AGE = 1.minute
What's the best way to pass the error message from the Comment controller to the (Server-generated Javascript Response) view?
if @comment.status == "locked"
render "comments/too-old", locals: {message: "You can't delete this comment now as it's more than #{time_ago_in_words(AGE.ago)} old."}
end
This currently fails as we're not allowed to use time_ago_in_words in a controller:
undefined method `time_ago_in_words'

The method time_ago_in_words is from ActionView::Helpers::DateHelper helper which will be automatically included in views.
If you need to access this method from controller then, you need to include this helper in the controller.
Assuming the controller name is CommentsController and action name as destroy:
include ActionView::Helpers::DateHelper
class CommentsController < ApplicationController
def destroy
...
if @comment.status == "locked"
render "comments/too-old", locals: {message: "You can't delete this comment now as it's more than #{time_ago_in_words(AGE.ago)} old."}
end
...
end
end

This is nowhere documented. As this method is available in a module, we can include wherever needed.

I'm not sure you're following my gist. The Rails documentation is not rigorous enough. How on earth is one supposed to learn this stuff?
