FieldMaskedModel

FieldMaskedModel provides masked accessor methods to model classes.

Installation

Add this line to your application's Gemfile:

gem 'field_masked_model'

And then execute:

$ bundle

Or install it yourself as:

$ gem install field_masked_model

Usage

For example, you have .proto file shown below.

// proto
syntax = "proto3";
package organization.service;

option ruby_package = "UsersPb";

message User {
  int64 id = 1;
  string name = 2;
  int32 age = 3;
  Profile profile = 4;
}

message Profile {
  int64 id = 1;
  string introduction = 2;
}

By using FieldMaskedModel::Base, you can get model classes with masked accessor methods.

# user.rb
class User < FieldMaskedModel::Base
  msgclass UsersPb::User
end

# profile.rb
class Profile < FieldMaskedModel::Base
  msgclass UsersPb::Profile
end
$ u = User.new(
*   field_mask: Google::Protobuf::FieldMask.new(
*     paths: [
*       "id",
*       "name",
*       "profile.id",
*       "profile.introduction"
*     ]
*   ),
*   message: UsersPb::User.new(
*     id: 3,
*     name: "Taro",
*     profile: UsersPb::Profile.new(
*       id: 4,
*       introduction: "My name is Taro"
*     )
*   ),
* )
=> <User
 id: 3,
 name: "Taro",
 age: -,
 profile: Profile>

$ u.id
=> 3

$ u.name
=> "Taro"

$ u.age
=> FieldMaskedModel::InaccessibleError: age is not specified as paths in field_mask!

$ u.profile
=> <Profile
 id: 4,
 introduction: "My name is Taro">
