Instance Method Details

#delete_param(k) ⇒ Object

Destructively delete a parameter, whether it’s in GET or POST. Returns the value of the deleted parameter.

If the parameter is in both GET and POST, the POST value takes precedence since that’s how #params works.

def delete_param(k)
  v = [ self.POST.delete(k), self.GET.delete(k) ].compact.first
  @params = nil
  v
end

#update_param(k, v) ⇒ Object

Destructively update a parameter, whether it’s in GET and/or POST. Returns nil.

The parameter is updated wherever it was previous defined, so GET, POST, or both. If it wasn’t previously defined, it’s inserted into GET.
