one of my methods receives a sort parameter either as
params => {“sort”=>{“criteria”=>“1”} }
OR
params => {“sort”=>“1”}
presently, I assign a variable @sc as follows :
params[:sort].nil? ? @sc = “1” : @sc = params[:sort][:criteria]
how can I assign @sc to params[:sort][:criteria] OR params[:sort]
whatever received… ?

You could try something like
stuff = params[:sort]
@sc = stuff.is_a? String ? stuff : stuff[:criteria] unless stuff == nil
Maybe I did not understand your question properly, if this does not seem
to work, please try to elaborate…

First of all you cannot mix symbol and string keys, i.e. you cannot use
a symbol to retrieve a string key:
irb(main):001:0> h={“sort”=>1}
=> {“sort”=>1}
irb(main):002:0> h[:sort]
=> nil
Maybe you want something like this:
tmp = params[“sort”]
@sc = Hash === tmp ? tmp[“criteria”] : tmp

h = {“sort”=>{“criteria”=>{“criterion”=>{“foo”=>“1”}}}}
Get the innermost value.
while (h = h.to_a.flatten.last).class == Hash do end
p h
