我正在尝试将我的Rails 5应用程序部署到Heroku。我刚刚设置了mLab，但是我的Heroku应用程序页面上写着＆＃34;肯定存在错误。＃34;
我按照说明seen here。我虽然是初学者，所以我并不完全理解我所做的一切，完全诚实。
这是我的宝石文件，以防万一：

mongoid.yml的相关部分：
# mongoid

default:
# The standard MongoDB connection URI allows for easy
# replica set connection setup.
# Use environment variables or a config file to keep your
# credentials safe e.g. <%= ENV['MONGODB_URI'] %>.
uri: <%= ENV['MONGOLAB_URI'] %>
options:
# The default timeout is 5, which is the time in seconds
# for a connection to time out.
# We recommend 15 because it allows for plenty of time
# in most operating environments.
connect_timeout: 15

我知道这很重要，非常感谢任何回复的人！
编辑：这是routes.rb：
Rails.application.routes.draw do
resources :people, except: [:show]
root to: "people#index"
end
people_controller.rb：
class PeopleController < ApplicationController
def index
@people = Person.all
end
def new
@person = Person.new
end
def create
@person = Person.new(person_params)
if @person.save
redirect_to people_path, notice: "The person has been created!" and return
end
render 'new'
end
def edit
@person = Person.find(params[:id])
end
def update
@person = Person.find(params[:id])
if @person.update_attributes(person_params)
redirect_to people_path, notice: "#{@person.first_name} #{@person.last_name} has been updated!" and return
end
render 'edit'
end
def destroy
@person = Person.find(params[:id])
@person.destroy
redirect_to people_path, notice: "#{@person.first_name} #{@person.last_name} has been deleted!" and return
end
private
def person_params
params.require(:person).permit(:first_name, :last_name, :email, :notes)
end
end
