Instance Attribute Details

#config ⇒ Hash

Return the configuration hash for the configured application for this client. This method caches the configuration after the first time it is fetched. The accompanying ‘masterKeyOnly` map (if returned by the server) is cached alongside it and exposed via #master_key_only.

Returns:

  • (Hash) —

    force fetch the application configuration hash.

attr_writer :config

#master_key_only ⇒ Hash{String=>Boolean}

Return the masterKeyOnly flag map for the application configuration. Keys map to ‘true` when the corresponding config param is only readable by master-key clients. Lazily triggers a config fetch on first access.

Returns:

  • (Hash{String=>Boolean}) —

    the cached masterKeyOnly map, or an empty hash if the server did not return one (e.g. non-master-key reads).

Instance Method Details

#config! ⇒ Hash

Returns force fetch the application configuration hash.

Returns:

  • (Hash) —

    force fetch the application configuration hash.

def config!
  @config = nil
  @master_key_only = nil
  self.config
end

#config_entries(master: false) ⇒ Hash{String=>Hash}

Return every config entry zipped with its masterKeyOnly trait.

Pass ‘master: true` to include keys whose `masterKeyOnly` flag is `true`; the default `master: false` filters those entries out, matching what a non-master-key client would actually observe. Each entry has the shape `{ value: …, master_key_only: Boolean }`. This is a client-side filter on the already-cached config — it does NOT re-request the config. When the connection is not authenticated with the master key, Parse Server has already stripped master-key-only entries before the response reaches the cache, so `master: true` has nothing extra to surface in that case.

Parameters:

  • master (Boolean) (defaults to: false) —

    when true, include master-key-only entries.

Returns:

def config_entries(master: false)
  config if @config.nil?
  return {} if @config.nil?
  flags = @master_key_only || {}
  @config.each_with_object({}) do |(key, value), out|
    is_master_only = flags[key] == true
    next if is_master_only && !master
    out[key] = { value: value, master_key_only: is_master_only }
  end
end

#update_config(params, master_key_only: nil) ⇒ Boolean

Update the application configuration.

Pass ‘master_key_only:` to additionally mark (or unmark) which keys are only readable by master-key clients. Parse Server merges this map into the existing flags; unspecified keys keep their current flag. Note that Parse Server rejects masterKeyOnly entries for keys that do not exist in `params` (either in this PUT body or already stored).

Parameters:

  • params (Hash) —

    the hash of key value pairs.

  • master_key_only (Hash{String=>Boolean}, nil) (defaults to: nil) —

    optional flag map to merge into the server-side masterKeyOnly settings.

Returns:

  • (Boolean) —

    true if the configuration was successfully updated.
