accessing model methods in views

[Ming]

class Catalog
include DataMapper::Resource

storage_names[:default] = 'main'

property :id, Integer, :field => 'code', :key => true
property :item, Text

has n, :subcatalogs

def slug
"whatever"
end
end

if i try to call slug in a view, where c is an instance of Catalog,

c.slug

yields an undefined method error.

Yet c.id and c.item access just fine.

This seems impossible. You will need to post your view code so we can see it.

OK. I ran the debugger and figured out the problem, which unless I
misunderstand, is not correct behavior.

in the view index.haml.html,

the assignment,

- x = c.slug

then the use of x,

= url(:catalog, x)

works fine

BUT, direct use of the method call,

url(:catalog, c.slug)

produces a undefined method error.

Can you send your view code and your controller code? The snippets are not enough.
