glia-errors

Implements Glia errors in Ruby and provides utilities to easily construct them.

Installation

$ gem install glia-errors

Usage

Require library

require 'glia/errors'

For Glia developers

Map from dry-validation result

Currently 2 dry-validation versions are supported:

• v0 up to 0.13
• v1 up to 1.6

schema = Dry::Validation.Schema do
  # ...
end
result = schema.(input)
error = Glia::Errors.from_dry_validation_result(result)
response = error.to_h

Specifying mapping for custom error message

If you have custom dry-validation predicates and error messages you can specify a custom error map. Custom error map takes priority over standard error mapping.

When custom error appears to be quite common consider adding it to this library instead.

ERROR_MAP = {
  'must be custom format' => lambda do |field, value, error_message|
    Glia::Errors::InvalidFormatError.new(field: field)
  end
}
error = Glia::Errors.from_dry_validation_result(result, ERROR_MAP)
response = error.to_h

For REST API integrators

require 'uri'
require 'net/http'
require 'openssl'
require 'json'

url = URI('https://api.glia.com/engagement_requests')

http = Net::HTTP.new(url.host, url.port)
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_NONE
request = Net::HTTP::Post.new(url)
request["Accept"] = 'application/json'
request["Content-Type"] = 'application/json'
request.body = '{}'

response = http.request(request)
code = response.code.to_i

if code >= 200 || code <= 299
  # Success
elsif response.header['Content-Type'] == 'application/json'
  # Glia error
  error = JSON.parse(response.read_body)
  case error['type']
    when Glia::Errors::INPUT_VALIDATION_ERROR
      # ...
    when Glia::Errors::UNKNOWN_ERROR
      # ...
    else
      # ...
    end
  end
else
  # Other error
end

Testing

Glia errors support multiple versions of dry-validation and tests are run against each supported major version. Under the hood we use Appraisal gem which generals additional gemfiles for each of the versions.

To run all tests use:

bundle exec rake test

To run tests only for dry-validation v1:

bundle exec rake test_dry_validation_v1

To run tests only for dry-validation v0:

bundle exec rake test_dry_validation_v0

Formatting

bundle exec rake format
