rake db：种子错误'rake aborted！错误:: ECONNREFUSED：拒绝连接'

Question

我正在尝试运行rake db:seed或bundle exec rake db:seed，并且会返回此错误。

rake aborted!
Errno::ECONNREFUSED: Connection refused - {:data=>"<?xml version=\"1.0\" encoding=\"UTF-8\"?><add><doc><field name=\"id\">Topic 3</field><field name=\"type\">Topic</field><field name=\"type\">ActiveRecord::Base</field><field name=\"class_name\">Topic</field><field name=\"topic_text\">Astronomy</field></doc></add>", :headers=>{"Content-Type"=>"text/xml"}, :method=>:post, :params=>{:wt=>:ruby}, :query=>"wt=ruby", :path=>"update", :uri=>#<URI::HTTP http://localhost:8982/solr/default/update?wt=ruby>, :open_timeout=>nil, :read_timeout=>nil, :retry_503=>nil, :retry_after_limit=>nil}

我的seeds.rb文件

# This file should contain all the record creation needed to seed the database with its default values.
# The data can then be loaded with the rake db:seed (or created alongside the db with db:setup).
#
# Examples:
#
#   cities = City.create([{ name: 'Chicago' }, { name: 'Copenhagen' }])
#   Mayor.create(name: 'Emanuel', city: cities.first)

您正在使用Solr，您需要启动它：

bundle exec sunspot-solr start -p 8982

和附注，你可以替换这一行：

Topic.create!(topic: 'Scuba Diving') unless Topic.where(topic: 'Scuba Diving').present?

Place.create!(place: 'Belgium' , name:'Belgium') unless Place.where(place: 'Belgium' , name:'Belgium').present? 

使用：

Topic.find_or_create_by!(topic: 'Scuba Diving')

Place.find_or_create_by!(place: 'Belgium' , name:'Belgium')
