How do you mock params when testing a Rails model's setter?-Collection of common programming errors

Can we see the whole stack trace? Where does it think String#stringify_keys! is being called?

Also, params looks odd to me. Is tasks.build() expecting input like this: ["new_tasks_attribute", {"name" => "paint fence"}] ?

If not, maybe you actually want Hash#each_key() instead of Hash#each()?

Need more data. Also, you might consider a Ruby tag to accompany your Rails tag.
