Question

I am writing a template for Rails 3 (you can find it here), and I m having troubles with the following lines:

# 8. config/database.yml modifications
if yes?("Do you want to set the database host to  /var/run/postgresql ?")
  inject_into_file "config/database.yml", " host: /var/run/postgresql
", :after => "development:
"


  # FIXME these two won t work :(((( why????
  # inject_into_file "config/database.yml", " host: /var/run/postgresql
", :after => "production:
"
  # inject_into_file "config/database.yml", " host: /var/run/postgresql
", :after => "test:
"


  # Not finding other solutions, I rewrite the two blocks above with two seds
  run %q(sed -i  /test:/a  host: /var/run/postgresql  config/database.yml)
  run %q(sed -i  /production:/a  host: /var/run/postgresql  config/database.yml)
end

也就是说,第一个投放者——书本作品,以及汇/数据库。页: 1 我

development:
  host: /var/run/postgresql

但是,其他两种注射器——纸面成功应用,但不会修改汇/数据库。因此,我

test:
  adapter: postgresql

and

production:
  adapter: postgresql

Answer 1

You have to specify the :force => true option to inject the same text multiple times. See:

http://rdoc.info/github/wycats/thor/master/Thor/Actions#insert_into_file-instance_odmeth

这一版本对我来说是有用的:

不要问我,这一选择为什么会有任何意义,th。

Answer 2

我在此 st卑地寻求解决一个略有不同的问题:

铁路公司说,以这种方式使用注射器。

inject_into_file  name_of_file.rb , after: "#The code goes below this line. Don t forget the Line break at the end
" do <<- RUBY 
  puts "Hello World"
RUBY
end

然而,这在我整个时间都没有奏效。在某些情况下,它实际上将把“投射”一词和一些废气编码带入试图注入的档案中。

最后,我表示,你只能通过<代码>inject_into_file。 a 体积,而且非常容易。

inject_into_file  name_of_file.rb , :after => "#The code goes below this line. Don t forget the Line break at the end
" do
  "Hello World"
end
