Rails : Trouble installing attachement_fu on Heroku

Question

I'm trying to deploy an app on heroku. My trouble is to install hattachement_fu plugin.

I ran the following command to install it directly on the server.

heroku plugins:install http://github.com/technoweenie/attachment_fuand"

and I get the following message :

Unable to load plugin: some_plugin: uninitialized constant ActiveRecord 
Already up-to-date. 
attachment_fu installed

So seams that the plugin is installed but something get wrong above ... But in my logs I continue to get :

NoMethodError (undefined method `has_attachment' for #<Class:0x2b3fed47a830>):

Like if the plugin was not there.

Any idea about what's going on ?

Answer 1

That's not how plugins work. The command you used is for installing plugins to the heroku command line tool.

If you want to install a Rails plugin, go to your project folder and script/plugin install foo (or however your version of rails installs plugins), commit it, then push to heroku.
