将具有不同名称空间的 rake 任务放在任务下的不同文件夹中是一个好主意吗？如果只有一个具有不同名称空间的文件应该怎么做？
我有一个奇怪的问题.在开发中这个问题不存在,但在生产中rake将这个错误消息抛给我"未初始化的常量程序"
"程序"是一个活动的记录模型,它就在那里,它位于模式文件中,它位于app/model文件夹中.
我执行它就像这个rake import:xml RAILS_ENV = production.可能是什么问题呢？下面是完整的堆栈跟踪
rake import:xml RAILS_ENV=production --trace
(in /usr/mobloom/www/htdocs/remindertest)
** Invoke import:xml (first_time)
** Invoke environment (first_time)
** Execute environment

我写了一篇文章ruby gem,我希望有一个rake任务,用于将gem发布到我自己的GemInABox存储库中:http://my-gem-repo.com.
实现这一目标的最简单方法是什么？
另外,我想阻止默认发布到Rubygems.org.
对于我的Rails应用程序,我想建立一个耙的任务,将用10填充数据库invoices的每个user:
def make_invoices
User.all.each do |user|
10.times do
date = Date.today
i = user.invoices.create!(:number => user.next_invoice_number,
:date => date += 1.year)
i.save
end
end
end
我如何增加date一年？
我已经建立了一个rake任务 -
# SET RAKE TASK NAMESPACE
namespace :db do
# RAKE TASK DESCRIPTION
desc "Fetch property information and insert it into the database"
# RAKE TASK NAME
task :insert_properties do

system("Template='#{params[:template]}' Theme='#{params[:theme]}' rake assets:precompile)
我从UI获取了两个值(params [:template],params [:theme]).我想在另一个路径(站点路径)中运行此任务的另一个意思是管理端UI是那个任务应该在Site目录中执行,
if(params[:theme_script] == "true")
template=Template.where(:name => params[:template]).first
if template
theme = template.themes.where(:name => params[:theme]).first
if theme
# Dir.chdir "#{THEMEPATH}"do
# `Template="#{template.name}" Theme="#{theme.name}" rake assets:precompile`
# end
# sleep 10
# system("#{Rails.root.to_s}/lib/shell_script.sh")
# RunRake.run_rake(template.name,theme.name)
# Dir.chdir "#{THEMEPATH}"do
# Rake::Task['assets:precompile'].invoke

ENV["Template"] = template.name
ENV["Theme"] = theme.name

我正在编写一个 rake 任务，它的功能是从其他网页获取信息。为此，我使用 open-uri 和 nokogiri。我已经在开发中进行了测试并且它可以完成工作，但是随后我部署到生产服务器并失败了。
这是代码：

require 'nokogiri'
desc 'recover eventos llerena'
task recover_eventos_llerena: :environment do
enlaces = []
# Getting index and all links
url = open(URI.parse("https://llerena.org/eventos/lista"))
page = Nokogiri::HTML(url)
page.css("a.fusion-read-more").each do |line|
enlaces.push(line.attr('href'))
end
enlaces = enlaces.uniq
#Inspecting everyone of them
enlaces.each do |link|
url = open(URI.parse(link))
page = Nokogiri::HTML(url)
title = page.css("h1").text
if Evento.find_by_titulo(title) == nil
description = page.css(".tribe-events-single-event-description.tribe-events-content.entry-content.description p").text

我不能以这种方式将这两项工作结合起来，还是需要单独运行？
如果我通过heroku run它运行任务。heroku run用于执行您的作业，因此您可以放心，如果它与 heroku run 一起工作，它将在调度程序中工作。
