ruby - Insert into Rails Database -

I'm new to Ruby on the Railways and wanted to create a crawler that snaps data and incorporates it into the database. I am currently using Heroes so that I can not use the database directly and the best way to integrate a crawler script in the ROR framework is that what will happen. I'm using an hour or daily cron to run the script.

If you are using Rail on Heroku, you can use only one ORM adapter like Datamapper or Active Recorder This gives you access to your database but basically via a layer. If you need to send a raw SQL to the database but it is usually not recommended because the ORM has provided you much more.

In a table you will basically just model in general and related areas such as Rail applications.

  RAIL G. PODMATA MetaTit: String Page_title: string RAKE DB: MIGRATE # IT MUCH MUCH HACOCK RAKE DB: Migrate "   Then your In the crawler script, you can create a record using your model ...  
  Page.create (: title => crawler [: title],: meta_title = & gt; crawler [ : MetaTitle])    Generally whenever you can (https://github.com/javan/whenever) to manage your cronjobs, Hirok I do not believe that this Cai Sector works because I have not set before Hrok.

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...
