Hi,

I am using the ‘acts\_as\_taggable’ gem and have issues when I try to  
‘tag’ an entity with a ‘tagname’ already defined.

i.e

1. book[1].tag(‘science’,‘paperback’) --\> works fine
2. book[2].tag(‘roman’,‘physics’,‘paperback’) --\> creates an exception  
for “paperback” as this tag is already existing in the ‘tags’ db.

Did anybody faced such issue?

I thought this a normal scenario…so not sure whether I am using it in  
a wrong way.

Any ideas?

Thanks, Hari

try:  
book[1].tag\_with("science paperback)  
book[2].tag\_with(“roman physics paperback”)

Otherwise you are not using the tagging engine to tag but just the old  
school has\_many.

Hi Jón,

I am using the ‘gem’ version of acts\_as\_taggable and there is no  
“tag\_with” option.

Does the following work with the module version?

In almost all cases. If you have a choice between a gem or a plugin.  
Choose the plugin.

I have tried with the “plugin” version and it doesn’t have this problem.

No idea what the issue with the gem!
