Looks like my wish list for rails currently is

\<%= radio\_button\_tag :school\_type, type, ‘’ %\>

This in my opinion should default to ‘not selected’ 🙂

Perhaps this is what you’re looking for:

\<%= radio\_button\_tag :school\_type, type, false %\>

The 3rd value is for ‘checked’ - which should be false or nil to be  
not checked.

my latest wish:  
That rails’ error reports told you what the local variables were [say,  
those that had been passed to a partial]

Rails can’t reflect true local variables, as a fundamental limitation of  
the  
language. However, if you pass :locals =\> { :@variable =\> value } as an  
instance  
variable, you might monkey-patch the Rails error formatter to reflect  
those.

def locals(&block)  
names = eval(“local\_variables”, block.binding) -  
[ActionView::Base.erb\_variable]  
names.map do |name|  
value = eval(name, block.binding)  
“#{name}: #{h value.inspect}”  
end.join ‘  
’  
end

and then in your view  
\<%= locals {} %\>  
(removing ActionView::Base.erb\_variable is just a convenience, it  
rather clogs up the output otherwise)
