assign_nested_attributes_for_collection_association should accept minimum limits
Reported by Aaron Lifton | June 30th, 2010 @ 11:06 PM
# activerecord/lib/active_record/nested_attributes.rb
def assign_nested_attributes_for_collection_association(association_name, attributes_collection)
options = nested_attributes_options[association_name]
# ...
if options[:limit] && attributes_collection.size > options[:limit]
raise TooManyRecords, "Maximum #{options[:limit]} records are allowed. Got #{attributes_collection.size} records instead."
end
# ...
end
This function should be able to accept minimum limits in addition to maximum limits, and raise TooFewRecords exceptions.

Here's my solution:
Instead of options[:limit], there would be options[:lower_limit] and options[:upper_limit], so both directions could be taken into account.
Then the code would be:
if options[:upper_limit] && attributes_collection.size > options[:upper_limit] raise TooManyRecords, "Maximum #{options[:upper_limit]} records are allowed. Got #{attributes_collection.size} records instead." end if options[:lower_limit] && attributes_collection.size < options[:lower_limit] raise TooFewRecords, "Minimum #{options[:lower_limit]} records are allowed. Got #{attributes_collection.size} records instead." endIs TooFewRecords even implemented?
