Ruby Reports

Hello,
I am referring the link below for creating the ruby reports.For creation of report_table, query is used for selecting only particular table.If i query the report_table, am getting error as "undefined method slice! for Hash".

Ex:
1. Author.report_table(:all, :only => ['id','name'])
If i use like this.I am getting error.
2. Author.report_table
If i use like this,its working properly.

I want to select only particular column from table.Please help me to do this.Its urgent.Thanks

I know this isn't what the tutorial says, but you could try At least, that is how the Active Record :select seems to work.

Thanks for the reply. Even that is not working for me.
We can also use Author.report_table_by_sql("select .....")

It stinks when tutorials don't work the same way they tell you to do something. I'm not sure what you can do in this case. It may be best just to use Author.report_table_by_sql("select .....").
