(Help) Delete the params[:status] hash if it exists in the params hash.

Hello, I am currently learning RubyOnRails and I am not that experienced with programming. The headline is one of the "Code Challenge: More Parameter Modification" tasks and I just don't know what I am missing.

my answer so far: params[:status].delete(:user_id) if params[:status].has_key?(:user_id) and params[:status].delete(:status) if params[:status].has_key?(:status)

Would be grateful for a solution, everything else worked out fine so far :-)

That code can also be changed to...

if params[:status]
    params.delete(:status)
end

to make it a bit easier to read

I was stuck because I didn't use the () or [] appropriately. Where is some information on how they are different and what they mean?
