Hai everyone,  
I am using restful\_authentication plugin in my project. The relation  
between the category and user is has\_and\_belongs\_to\_many. So I created  
another table category\_users with category\_id and user\_id as fields. In  
my view i specified like the following.  
\<% for category in Category.find(:all) %\>  
\<%= category.name %\>  
\<%= check\_box\_tag(“user[category\_ids][]”,"#{category.id}")  
%\>  
\<%end%\>  
But when I tried to save the user model the categories of the user is  
not saving in the table category\_users. Data to the table users is  
saving. What I have to do for storing data to category\_users? (more than  
one category for a single user).  
Please help.  
Thanks in advance

Try to load up script/console, and check if user.category\_ids=  
[1,3,6,…] works …

Solve the issue by adding attr\_accessible :category\_ids in the model.  
But another error is coming ie  
undefined method `to\_sym’ for #State:0x665cc04  
installed the plugin with --include-activation and --stateful options.  
I dont’ understand the reason for that. Pls help.  
Any suggestions for a good documentation of using the  
restful\_authentication plugin?

Give us the context of where the error is getting raised.
