导轨 - RSPEC 不完整的多字节字符错误

Question

我正在使用 Rails 3.2.13 和 ruby 1.9.3。我不断收到以下错误：

Failure/Error: @user = Fabricate :user, role_ids: [role.id]
PG::Error:
   incomplete multibyte character
 # ./spec/controllers/api_controllers/projects_controller_spec.rb:6:in `block (2 levels) in <top (required)>'

关于该错误的令人沮丧的事情是它间歇性地发生。有时我可以运行 10 次测试而不会发生，然后其他时候每次都会发生。

发生错误的 projects_controller_spec.rb 文件第 6 行周围的代码如下所示：

require 'spec_helper'
describe Api::V1::ProjectsController do
  before do
    role = Fabricate :data_collector_role
    @user = Fabricate :user, role_ids: [role.id] # this is line 6
    @project = Fabricate.build(:project, proposal: Fabricate(:full_proposal))
    @project.save(validate: false)
    @permission = Fabricate :permission, user: @user, project: @project
    @project2 = Fabricate.build(:project, proposal: Fabricate(:full_proposal))
    @project2.save(validate: false)
    request.env["HTTP_ACCEPT"] = 'application/json'
    request.env['HTTP_AUTHORIZATION'] =   ActionController::HttpAuthentication::Token.encode_credentials(@user.api_key)
  end

在上面的第 6 行调用的 Fabricator 看起来像这样：

Fabricator :user do
    username { sequence(:username) { |n| "foo#{n}" } }
    password 'foobar'
    password_confirmation 'foobar'
    email_address "[e-mail]"
    home_phone "123456789"
    work_phone "456789189"
    sales_channel
end

相同的代码在其他不适用于 API 控制器的规范中被调用，并且它们在 100% 的时间内工作。

RSPEC 时不时地完全崩溃并给出以下错误：

     Failure/Error: get :show, { id: @project.id }
     ActiveRecord::StatementInvalid:

将其添加到文件规范/控制器/api_controllers/projects_controller_spec.rb 的顶部
