hello,

controller code that was working fine prior to the upgrade…

```
@foo = Foo.find( @params[:id] )
@bar = Bar.find( @foo.id_bar )

```

…is now throwing following error messages…

```
ArgumentError (wrong number of arguments (2 for 1)):
/usr/.../activerecord-1.14.4/lib/active_record/base.rb:941:in

```

`find_one' /usr/.../activerecord-1.14.4/lib/active_record/base.rb:941:in`find\_from\_ids’  
/usr/…/activerecord-1.14.4/lib/active\_record/base.rb:382:in  
`find’

All I’m trying to do is fetch a row from the db & refer to columnar  
data from that row (both in the controller & in the view). My current  
workaround (ugly) is to use the :all & :conditions switches for the  
find method, and then iterate over @foo to set variables as needed for  
columnar data. Real ugly.

What am I missing here? Bit of a newbie, so apologies in advance if  
it’s painfully obvious.

Cheers,

-ian

Have you defined your own one-parameter find\_one method in your model?  
If so, rename.

–  
We develop, watch us RoR, in numbers too big to ignore.

A suggestion - I don’t know if this will fix the snippet - but @params  
is deprecated.  
You should be using just params, without the instance var (@) prefix.
