Rails - Oct 2006 - create hash before model.find( _your_created_hash_ )

Maybe I should ask this in Ruby forum.
Can anybody tell me how to create a hash before invoke the
''find'' method
and use this hash as parameter for the method?

Smt like:

find_hash = Hash.new
if condition1
  find_hash[ :all ] = true ????
else
  find_hash[ :first ] = true ????
end


....

users.find( find_hash )

thank

find() accepts options hash as a second optional parameter. :first or
:all symbol is a method parameter, not a hash value. What you need is:
find_params = []
if condition1
  find_params[0] = :all
else
  find_params[0] = :first
end

all other options, such as limit, group or include should be placed in
the options hash, e.g. find_params[1] = {:include => :posts, :limit =>
10}

then the find method is called in this way: users.find(*find_params)
