我想用rspec测试控制器的动作和flash消息的存在.

行动:

def create
  user = Users::User.find_by_email(params[:email])
  if user
    user.send_reset_password_instructions
    flash[:success] = "Reset password instructions have been sent to #{user.email}."
  else
    flash[:alert] = "Can't find user with this email: #{params[:email]}"
  end

  redirect_to root_path
end

规格:

describe "#create" do
  it "sends reset password instructions if user exists" do
    post :create, email: "email@example.com"      
    expect(response).to redirect_to(root_path)
    expect(flash[:success]).to be_present
  end
...

但我有一个错误:

Failure/Error: expect(flash[:success]).to be_present
   expected `nil.present?` to return true, got false

我想在ActiveAdmin控制器中添加before_action过滤器.

我可以这样做:

before_action :set_product, only: [:show, :edit, :update, :destroy]

private

def set_product
  @product = Product.find_by_name(params[:name])
end

我的项目在当地运作良好.我把它部署到了Heroku.我有一些错误,应用无法在那里运行.我正在使用带有postgresql的rails 4.无法理解为什么会这样.在我看来,没有创建数据库.我应该在database.yml上添加指定生产设置吗？

database.yml的

development:
  adapter: postgresql
  encoding: utf8
  database: test_store_dev
  pool: 5
  username: mike
  password: mike
  host: 127.0.0.1

test:
  adapter: postgresql
  encoding: utf8
  database: test_store_test
  pool: 5
  username: mike
  password: mike
  host: 127.0.0.1

从日志:

在我的数据库中,有很多用户使用无效数据(没有手机号码).因为我刚刚添加了移动存在验证.当我尝试添加新事件时,我收到错误消息"用户移动电话号码必须是...格式".如何在创建事件时跳过用户验证？

event.rb

class Event < ActiveRecord::Base
  has_many :participations
  has_many :users, :through => :participations
end

user.rb

class User < ActiveRecord::Base
  has_many :participations
  has_many :events, :through => :participations
end

events_controller.rb

 def create
    @event = Event.new(event_params)

    respond_to do |format|
      if @event.save
        format.html { redirect_to events_path, notice: 'Event was successfully created.' }
      else
        format.html { render action: 'new' }
      end
    end
  end

_form.html.erb

 <%= form_for @event, :html => {:class => 'row'} do |f| %>
      <%= f.error_messages %>

      <%= f.label :name %>
      <%= f.text_field :name …

我正在尝试使用地理编码器获取当前坐标.

但

request.location.latitude
request.location.longitude 

总是为我返回0.0和0.0.是否可以使用地理编码器找到地理定位坐标？

提前致谢!
