dragonfly-gem

问题 We decided to try using RefineryCMS for our current project and have run into some issues. We began the project in a local development environment. The deadline is very quickly approaching. At first, we tried to move the project into production using a DreamHost server. There were issues with the images (Refinery uses Dragonfly), where our database dump wasn't brining any images over (or thumbnails). We have exhausted our resources and still can't find a solution to our problem. I've done

问题 In the comments to the solution for How do I find an image on a page with Cucumber/Capybara, somebody asked: I can't seem to figure how to get this to work with URLs generated by Dragonfly. They look like this: /media/BAh_some_long_string_AwIw/12_11_52_810_5x5.jpg?s=7e360000, where 5x5.jpg is my file name. I've tried something like: //img[@src="/media/ / #{image}?s=*"] but it doesn't work. Got any tips? – Ramon Tayag Feb 25 at 4:18 I have a similar problem, only worse - in my case, the

问题 I'm using a combination of Dragonfly and rack/cache hosted on Heroku. I'm using Dragonfly for uploaded assets. Thumbnails are processed on-the-fly and stored in rack/cache for fast delivery from memcached (via the Memcachier addon). Regular static assets are also cached in memcached via rack/cache. My problem is that any uploaded files over 1MB are causing a 500 error in my application. 2013-07-15T10:38:27.040992+00:00 app[web.1]: DalliError: Value too large, memcached can only store 1048576

问题 I'm using dragonfly ~> 0.9.15 Given an image, I'm confused at how to use the convert method in dragonfly to crop a circular portion from the image with transparent background. I am able to use a direct image magick command to run it from command line but the example command I found uses actual files and I'm unaware of how to get the file while dragonfly processes it on the fly. Here's the actual command I took from a stack overflow question with imagemagick. https://stackoverflow.com/a/999563

问题 I'm working on developing a refinerycms rails app that was working good locally and now i've moved it to my VPS and I was having issues with images that i uploaded through refinerycms not loading and i've been reading that i needed to upgrade my version of imagemagick. I upgraded from 6.2.8 to 6.7.8. Now the images all load on some pages, but not on the admin side. What is causing this issue? Here's the stacktrace of the error.

问题 We are using Dragonfly for file and image upload in the app and in the Rails Admin. Dragonfly in app part Users can apply for jobs and add their resume as attachment. When user uploads attachments and sucesfully apply for a job the files get deleted.

问题 I was having some problems getting the dragonfly gem to play nicely with passenger. Passenger doesn't seem to use the current $PATH so it can't find the convert binary. I've added some configuration to dragonfly which seems to solve the issue: require 'dragonfly/rails/images' Dragonfly[:images].configure do |c| c.convert_command = "/usr/local/bin/convert" # defaults to "convert" c.identify_command = "/usr/local/bin/convert" # defaults to "convert" end but the gem i'm working on is going to be
