Bad cases that you should never implement by yourself except for practice are encryption or a premature abstraction (framework, etc) that takes your more than 1 day or 2. ConclusionĬodes that are written 50 years ago with zero-dependencies are working fine today and the ones are written today with dependencies may not work tomorrow :)Īnd don’t get me wrong I don’t mean to reinvent the wheel but don’t be afraid to build your own tool since each app has different needs and not all gems/libraries are going to fit yours. This will be handled by a ErrorSerializer and a concern called ActsAsJSONAPI which I’ve written to handle different cases of serialization and error handling without dependencies and a lot of complexity which you can check out here. Result = ApprovedMvp.new(minimal_viable_product) Here we populate a decorated MVP with contextual errors and pass it up to the controller class UseCases::MinimalViableProductsController < ApplicationController The validate method receives the model attributes as well as any options passed to set or save, if validate returns an error, save does not continue, the model.
#Activerecord validation check without populating errors code#
Let’s take look at the code class ApprovedMvp < SimpleDelegatorĮrrors.add(:minimal_viable_product, "it should be submitted first")Įrrors.add(:minimal_viable_product, "already been approved by user") > MVPs cannot be approved unless they have enough approvals from different users > MVPs cannot be approved more than once by same user # This will generate and refresh user's token and return if no user found it will set variable to nil and user presence validation will handle the error which keeps us from writing an error handling part except a message.Īnd the controller would be like class LoginController MVPs cannot be approved before they're submitted
Super(params.require(:user).permit(:email, = User.find_by(email: email, status: :active)&.authenticate(password)
So we have 2 cases which we have to cover in our implementation to do that I use ActiveModel::Validations to validate the parameters I receive from the controller and using save method to keep interface consistency.
#Activerecord validation check without populating errors password#
> Users cannot login with wrong password / email However articles do not have to be in a group or be a response to another. Let’s consider a user logging in use case > Users can login with password and email
In the favour of simplicity and the fact that I never trust dependencies due to the complexity they bring in I’ve been using ActiveModel and SimpleDelegator to apply service objects through a consistent interface across the controllers as well as avoiding dependency clutter and here are the results. class Reservation < ActiveRecord::Base attraccessible :enddate, :roomtype, :startdate validates :startdate, :presence > true validates :enddate, :presence > true validate :reservationdatesmustmakesense private def reservationdatesmustmakesense if enddate < startdate errors.considering the fact that they are practiced for so long and they can be accomplished using just the batteries already included in Ruby On Rails service objects are no different for which developers often end up using different gems to do such a simple pattern. One of the worst practices in Ruby On Rails is to clutter the Gemfile to do basics as authentication, authorization, validation, etc.
