When you use attachment\_fu plugin you have to use one of the image processing libraries. However, when more of them are installed I get the error: no such file to load – application.rb How can I force attachment\_fu to use one specific image library? ---

You’ll need to give more information probably. Have you configured you model to use attachment\_fu? That is usually where you specify the processing. Reply with that and you might more help. Also what specifically are the processors you have installed? Are you sure that error isn’t related to something else going on in your controllers?

I had similar problems using attachment\_fu for one project that I’m currently developing, You need to provide more info about the error and your app configuration, I will personally use paperclip is a great plugin, it has a smaller footprint and it has more options than attachment fu plus you can find some useful tutorials about how to use it.

I switched to Paperclip and it is working now 🙂 Should have done that a long time ago 🙂 Milan D. wrote: > OK, what I did was rename the application\_controller.rb to > application.rb and it started working.

OK, what I did was rename the application\_controller.rb to application.rb and it started working. But only on localhost. On the server it won’t create any model with attachments (even if I don’t specify the picture - works fine on localhost). I changed the mode to 777 to make sure that there are no permission issues and nothing happened. I have all of the libraries installed on server (rmagick, image\_science and mini\_magick). If I put gem.config in environment.rb it says that I need to install the gem (both on localhost and server). I’ve read somewhere that that is the issue with rails 2.2.2. I have also tried specifying :with =\> :mini\_magick in the has\_attachment options to force the plugin to use the specific library and it still wouldn’t create the model. Maybe I should try out paperclip. P.S. Everything is working on the localhost. I have the feeling that this is a configuration issue. Is there any way for gem dependencies to break or something similar?
