So if I do this:
class Errors < ActiveRecord::Base
def crtd_x
crtd.strftime("%Y-%m-%d")
end
...
end
errs = Errors.find(:all, :conditions => ...)
errs.to_xml(:methods => [:crtd_x, ...])
It fails with a NoMethodError: You have a nil object when you didn't
expect it!
The error occurred while evaluating nil.strftime
If I understand correctly, Errors (a subclass of ActiveRecord::Base)
contains a list of rows, each of which would have a field called
"crtd". But at the level I'm calling to_xml, there is no field
"crtd". What I need for my custom function is something like this
(pseudocode):
def crtd_x
current_error.crtd.strftime("%Y-%m-%d")
end
I think I'm close. Please advise how I can make crtd_x() operate on
the current item in the collection rather than on the whole
collection.
Thanks much,
Michael
