ruby - rails 3 access to model and mailer from external script -

How can I use models and mailers from Ruby Script in a topic? I think of something that is not related to the web and can not be done through rail, but are bound to the database used in the rail. For example, when I want to send an email to Sb Premium ends and 7 days ago I am the best relation

Set a rake function that you can call and check the output Are there. lib / tasks / appname.rake

  function in   do_some_stuff = & gt; : Environment # You want any code in "End of some output" End

visual studio 2010 - How to reinstall MVC 2 tools for VS2010? -



    I uninstalled ASP.Net MVC 2 device for Visual Studio 2010. How can I restore it? MVC2 downloads seem to include only the VS2008 device.   Whatever I said, says that MVC 2 has been included in VS2010, but the installation of an improvement did not fix it, and MVC 2 is not listed.

This is your  show-ref .  You ask "Is there anything in this safe / head in the safe?"  I ask, "what current  head  exists?"   In practice, both of these are fair tests, because once you have a branch, so to achieve the  HEAD , some mock values will indicate manually lack of editing It is very diffic...
