Rails 5 adds more control to fine tuning SSL usage
Adding HTTPS support is one of the first steps towards enhancing the security of a web application. Even when a web app is available over https, some users may end up visiting the http version of the app, losing the security https provides. It is important to redirect users to the https URLs whenever possible. Forcing HTTPS in Rails We can force users to use HTTPS by setting config.force_ssl = tru

Errors can be indexed with nested attributes in Rails 5
We use accepts_nested_attributes_for when we want a single form to cater to multiple models. By using this we can easily provide attributes for associated models. In Rails 4.x, if a validation fails for one or more of the associated models, then it is not possible to figure out from error message, which of the associated model object is the error related to. 1 2class Product < ApplicationRecord 3h
Rails 5 Warning when fetching with Active Record
With large data set we can run into memory issue. Here is an example. 1 2>> Post.published.count 3=> 25000 4 5>> Post.where(published: true).each do |post| 6 post.archive! 7 end 8 9# Loads 25000 posts in memory 10 Copy Rails 5 adds warning when loading large data set To mitigate issue shown above Rails 5 has added config.active_record.warn_on_records_fetched_greater_than.

accessed_fields to find active fields in application
Rails makes it very easy to select all the fields of a table. Above code is selecting all the columns of the table users. This might be ok in most cases. However in some cases we might want to select only certain columns for performance reason. The difficult task is finding what all columns are actually used in a request. To help in this task, Rails 5 has added accessed_fields method which lists a
Rails 5 Expression Indexes & Operator Classes support
Let's assume that in our health care application we have a page which shows all Patients. This page also has a filter and it allows us to filter patients by their name. We could implement the filter as shown here. 1 2Patient.where("lower(first_name) = ?", first_name.downcase) 3 Copy There might be many users with the same name. In such cases, to speed up the search process, we can add an index. Bu
Partial template name without Ruby identifier Rails 5
Before Rails 5, partials name should start with underscore and should be followed by any combination of letters, numbers and underscores. This rule was required because before commit, rendering a partial without giving :object or :collection used to generate a local variable with the partial name by default and a variable name in ruby can't have dash and other things like that. In the following ca
Specific mime types in controller tests in Rails 5
Before Rails 5, while sending requests with integration test setup, we needed to add format option to send request with different Mime type. 1 2class ProductsControllerTest < ActionController::TestCase 3 def test_create 4 5 post :create, { product: { name: 'Rails 5 book' } }.to_json, 6 format: :json, 7 headers: { 'Content-Type' => 'application/json' } 8 9 assert_equal 'application/json', request.c

Rails 5 supports adding comments in migrations
Database schemas change rapidly as project progresses. And it can be difficult to track purpose of each table and each column in a large project with multiple team members. The solution for this problem is to document data models right from Rails migrations. Solution in Rails 4 You can add comments in Rails 4.x migrations using gems like migration_comments and pg_comment. Solution in Rails 5 Rails
