每当我尝试运行cap production deploy它时,在以下命令失败

[ebbf9fde] Command: cd /var/www/apps/my_app/releases/20150803171251 && /usr/local/rvm/bin/rvm 2.2.2 do bundle install --path /var/www/apps/my_app/shared/bundle --without development test --deployment --quiet
DEBUG [ebbf9fde]    /usr/local/rvm/scripts/set: line 19: exec: bundle: not found

我添加了一个用户'deploy'来执行此部署,输出rvm list是

$ rvm list

rvm rubies

=* ruby-2.2.2 [ x86_64 ]

# => - current
# =* - current && default
#  * - default

进一步运行gem列表的输出是

$ gem list

我正在定义一个名为“联系人”的表中存在的一些字段的验证：

class Contact < ActiveRecord::Base
    validates :nome, :cognome, :indirizzo_abitazione, 
              :numero_civico, :indirizzo_email, :prefisso_cellulare, :cellulare, presence: true
    validates :nome, :cognome, :indirizzo_email, 
              :prefisso_cellulare, :cellulare, uniqueness: true
    validates :indirizzo_email, format: { with: /\A([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})\z/i, on: :create }
end

如果存在错误，我想利用引导程序的类属性“has-error”以红色突出显示特定字段；所以我试图以这种方式做到这一点：

  <div class="form-group <%= @contact.errors[:name] ? "has-error" : "" %>" >
    <%= f.label :name , :class => "control-label" %><br>
    <%= f.text_field :name, :class => "form-control" %>
  </div>

但是当我登录到这个页面时，该字段已经是红色的。有没有一种方法可以查看在验证一条记录期间，特定字段是否出现错误？

我正在使用Rails 4.2.3.我无法将可变数量的搜索条件传递给我的Rails finder方法.我有

    user = current_user
    search_criteria = ["my_objects.user_id = ?"]
    search_values = [user.id]
    start_date = params[:start_date]
    if start_date.present?
      start_date_obj = Date.strptime(start_date, "%m/%d/%Y")
      search_criteria.push("my_objects.start_date >= ?")
      search_values.push(start_date_obj)
    else
      start_date = my_object.find_user_first_my_object_date(user)
      @default_start_date = start_date.to_time.strftime("%m/%d/%Y") if start_date.present?
    end
    end_date = params[:end_date]
    if end_date.present?
      end_date_obj = Date.strptime(end_date, "%m/%d/%Y")
      search_criteria.push("my_objects.end_date <= ?")
      search_values.push(end_date_obj)
    else
      end_date = my_object.find_user_last_my_object_date(user)
      @default_end_date = end_date.to_time.strftime("%m/%d/%Y") if end_date.present?
    end
    distance = params[:distance]
    if distance.present?
      distance_parts = distance.split(" ")
      search_criteria.push("my_objects.distance = ?")
      search_criteria.push("my_objects.distance_unit_id = ?")
      search_values.push("#{distance_parts[0]}")
      search_values.push("#{distance_parts[1]}")
