    There is the present? Method that checks for existence and not nil:

    if ra[:address].present?
    ....

    ra[:address] is already falsy if it's nil, the second check is redundant 👀

    @TeeSeal this will throw an error if no key with that name exists though.

    @fuckwit Hashes do not throw errors for keys that do not exist. They return nil, or whatever default you provide.

    @Puroguramingu Your variable naming is ghetto.

    @Root yeah remembered that after it was too late to edit the comment.

    This method is mainly for checking if it exists and has a value that is not nil, empty string, whitespace string, empty array/hash or false.

    @fuckwit Yap. #present? is probably the method I miss most when working on Ruby (non-Rails) projects.

    @Puroguramingu Glad, because it's pretty smelly. 😋

    (Also, I can't see the image.)

    @root haha I wouldn't be caught writing that. The images should be working again hopefully.
