triggered when respond_with is called. The simplest case to study is a GET request: class PeopleController < ApplicationController respond_to :html, :xml, :json def index @people = Person.all respond_with(@people) end end When a request comes in, http://api.rubyonrails.org/classes/ActionController/Responder.html for example for an XML response, three steps happen: 1) the responder searches for a template at people/index.xml; 2) if the template is not available, it will invoke #to_xml
on the https://rails.lighthouseapp.com/projects/8994/tickets/1687-flexible-formatting-for-ar-validation-error-messages given resource; 3) if the responder does not respond_to :to_xml
, call #to_format
on it. Built-in HTTP verb semantics The default Rails responder holds semantics for each HTTP verb. Depending on error message the content type, verb and the resource status, it will behave differently. Using Rails default responder, a POST request for creating an object could be written as: def create @user = User.new(params[:user]) flash[:notice] = 'User was successfully created.' if @user.save respond_with(@user) end Which is exactly the same as: def create @user = User.new(params[:user]) respond_to do |format| if @user.save flash[:notice] = 'User was format error messages successfully created.' format.html { redirect_to(@user) } format.xml { render xml: @user, status: :created, location: @user } else format.html { render action: "new" } format.xml { render xml: @user.errors, status: :unprocessable_entity } end end end The same happens for PATCH/PUT and DELETE requests. Nested resources You can supply nested resources as you do in form_for and polymorphic_url. Consider the project has many tasks example. The create action for TasksController would be like: def create @project = Project.find(params[:project_id]) @task = @project.tasks.build(params[:task]) flash[:notice] = 'Task was successfully created.' if @task.save respond_with(@project, @task) end Giving several resources ensures that the responder will redirect to project_task_url instead of task_url. Namespaced and singleton resources require a symbol to be given, as in polymorphic urls. If a project has one manager which has many tasks, it should be invoked as: respond_with(@project, :manager, @task) Note that if you give an array, it will be treated as a collection, so the following is not equivalent: respond_with [@project, :manager, @task] Custom options respond_with also allows you to pass options that are forwarded to the underlying render call. Those options are only a

I'd like to propose a more flexible solution - instead of only making the separator configurable, use interpolation to construct the messages. Inside a locale file: en: activerecord:
