I’ve installed the plugin for taggable steroids, read the read me,  
followed the instructions, but I’m getting the error ‘undefined method  
tag\_list’. How is that possible? I assume that the method tag\_list  
should be included as part of the plugin and there’s no mention of  
anything in the readme, etc. What am I doing wrong here? Is there some  
code I need to add into the plugins directory? Where should this  
method be found (it’s not in the project at all)?

TIA

how far did you follow it? did you define acts\_as\_taggable in your  
model?  
did you run the migrations?

yep, right. using acts\_as\_taggable in your model should add those  
functions

if you followed the installation process with:  
ruby script/plugin install …  
it should have put the code in the folder  
vendor/plugins below you project root.  
if it’s not there, something went wrong.

next:  
restart the server. otherwise the plug won’t be loaded.

run the migrations, make sure the tags and taggings tables exist

in your model declare  
acts\_as\_taggable

that should be all…

Thanks for your reply, yes I did follow all the instructions.  
restarting the server did not help. i went back to an earlier version  
and redid the plugin install, etc. and it worked fine this time. I  
guess something just came in wonky on my first try. Thanks for the  
sanity check.
