Question

In my application, I’m using Resque to resize images. If an image is in the resizing queue, I want to show a “resizing image” icon.

This means that I need to be able to find all current jobs relating to a specific model ID in the queue. Right now I do it like this:

Resque.peek(:resize, 0, 100).find_all { |job| /#{model.id}/.match(job["args"][0]) }

This is stupid. But is there any way to query the Resque queue to find all jobs where the first argument is equal to [id]?

Thanks in advance.

Answer 1

Instead of querying resque queue, you should store image meta-data along with your model.

Lets assume you are storing product images. You are likely using a Redis hash to store product details. Just add another flag like this –

hset product:123 is_resizing true

You can them perform a simple lookup to show the resizing image icon. At the end of your resque job, delete the is_resizing key, and add the resized_image_url key.
