ruby on rails - Check if given string is an URL -

In my rail application, I need to verify whether the URL given by the user is really a URL. I only use the HTTP protocol (And possibly HTTPS, I have not paid any attention to it at all), which makes me believe that there may be something in the train already that can work for me.

If not: Can you recommend a regex string? I have found something after googling but all of them have one or two problems according to user comments.

Thanks

  def uri? (String) Yuri = URI String (string)% w (http https) .include? (Uri.scheme) Rescue URI :: Evil Error False URI :: Invalid URIA RRF Last    This is a very simple example. The advantage of using the  URI  library on regular expressions is that you can do complex tests.

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. Add VS2010 / Select a component in the Remove screen.      You will get your VS2010ToolsMVC2.msi VS2010 DVD under WCU \ ASPNETMVC - hopefully it will do!    






Git Bash script to check whether repo has any commits? -



    I have a script on which I need to work differently if there is one, which is one or more , Commits. What is the best way to do this?   Something like this will appear in the proxy code.    #! / Bin / bash if [[`git log_count`] ==" 0 "]]; Then there is no commodity for this repo. # What goods ... and echo are "one or more committed!" # What are the other things?    Any ideas?      you can    git rev-parse -verify HEAD    (after :)     This is a pipeline command, and its behavior vs. "  git diff " There is very little possibility to change   I find it more pronounced  rev-parse -verify  means "is this a valid object name?"    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...
