Dealing with active record validation exceptions

[cmuhire]

A failed active record validation (ex: validates :names, presence: true) produces a 422 (Unprocessable Entity) error response which will be handled by Gaffe.

Is there a way to circumvent this so as to deal with failed validations in the original controller without having to resort to a rescue clause in every create/update method?

Thanks for this handy gem by the way!

As far as I know, .create, .update and #save don’t raise exceptions — .create!, .update! and #save! do. So if you want to handle errors in the original controller:

class FooController < ApplicationController
  def create
    foo = Foo.create(foo_params)

    if foo.save
      redirect_to foo_path(foo)
    else
      render json: { errors: foo.errors }, status: :unprocessable_entity
    end
  end
end

Gaffe won’t handle any 422 error in the above code.

You are right! My bad, I was using a bang update method. Thanks a bunch :)

Alright, I’ll close the issue. 😄
