Instance Method Details

#parse_file? ⇒ Boolean

Determines whether the hash contains Parse File JSON metadata fields.

Accepts the canonical Parse Server file-pointer shapes:

  • {name, url} (count == 2) with name == File.basename(url path)
  • {__type: "File", name, url} (any count) with the same basename equality

The URL's query string is stripped before computing basename so short-TTL presigned URLs that Parse Server's S3FilesAdapter returns on every read don't include the signature bytes in the comparison.

Returns:

  • (Boolean) —

    True if this hash contains Parse file metadata.

def parse_file?
  url = self[Parse::File::FIELD_URL]
  name = self[Parse::File::FIELD_NAME]
  return false unless url.present? && name.present?
  return false unless count == 2 || self["__type"] == Parse::File.parse_class
  path_only = Parse::File.strip_query(url)
  name == ::File.basename(path_only)
end

#parse_object ⇒ Parse::Object

Turns a Parse formatted JSON hash into a Parse-Stack class object, if one is found. This is equivalent to calling Parse::Object.build on the hash object itself, but allows for doing this in loops, such as map when using symbol to proc. However, you can also use the Array extension Array#parse_objects for doing that more safely.

Returns:

  • (Parse::Object) —

    A Parse::Object subclass represented the built class.
