I have tried just using an image tag and removing the asset timestamp after the image but it still displays the old image and I have also tried adding meta tags to stop browser caching

问题 I have a Sidekiq worker that does some background processing and then finally POSTs a success message to a 3rd party API. This message I post is essentially a "thank you" message and can contain HTML. In the message I'd like to link back to my site in a properly formatted way. This naturally sounds like a view to me. I'd love to simply use a view template, render it to HTML and finally post it off to the API. For the life of me, i cannot figure how to render a view from within my Sidekiq

The urls are generated in the controller, and image_url() doesn't seem to return the same result from the controller as it does

问题 I'm allowing my users to have multiple profiles (user has many profiles) and one of them is the default. In my users table I have a default_profile_id. How do I create a "default_profile" like Devise's current_user which I can use everywhere? Where should I put this line? default_profile = Profile.find(current_user.default_profile_id) 回答1: Devise's current_user method looks like this: def current_#{mapping} @current_#{mapping} ||= warden.authenticate(:scope => :#{mapping}) end As you can see,

问题 I have tried to Google a lot about Rails Garbage collector, but I didn't get a reliable answer. Has anyone got a source to show how garbage collection is implemented in Rails?

You should search for documentation about the Ruby Garbage Collector. You can start from the Ruby GC module. The GC module provides an interface to Ruby

问题 I have downloaded the Honeybadger webpack example and run bundle install .
