handle(*error_classes, severity: :warning, context: {}, fallback: nil, source: DEFAULT_SOURCE) public

Evaluates the given block, reporting and swallowing any unhandled error. If no error is raised, returns the return value of the block. Otherwise, returns the result of fallback.call, or nil if fallback is not specified.

# Will report a TypeError to all subscribers and return nil.
Rails.error.handle do
  1 + '1'
end

Can be restricted to handle only specific error classes:

maybe_tags = Rails.error.handle(Redis::BaseError) { redis.get("tags") }

Options

  • :severity - This value is passed along to subscribers to indicate how important the error report is. Can be :error, :warning, or :info. Defaults to :warning.

  • :context - Extra information that is passed along to subscribers. For example:

    Rails.error.handle(context: { section: "admin" }) do
      # ...
    end
    
  • :fallback - A callable that provides handle's return value when an unhandled error is raised. For example:

    user = Rails.error.handle(fallback: -> { User.anonymous }) do
      User.find_by(params)
    end
    
  • :source - This value is passed along to subscribers to indicate the source of the error. Subscribers can use this value to ignore certain errors. Defaults to "application".
