I had to rename your variables to follow your code, but it looks like your
mistake is at this line (translating back):
weth = arguments[0]
That sets variable 'weth' to be a reference to the *same object* that that
is referenced as arguments[0]. You then proceed to modify that object in
each iteration of the loop, and assign other references to it to your
result variable, but in the end it's still only one object.
Here's a version that I think will do what you want:
template = arguments[0]
param_groups = arguments[1]
results = {}
param_groups.each_pair do |ifc_num, params|
# key difference:
result = template.clone
# no need to clone other objects:
result['in_vlan'] = params['in_vlan']
result['options']['MTU'] = params['mtu']
# especially here:
results['eth' + ifc_num.to_s] = result
end
