Part 2 of Ruby on Rails Tutorial Online
An anonymous reader writes "Curt Hibbs has released Part 2 of his tutorial Rolling with Ruby on Rails to the O'Reilly ONLamp site. The first part was published in January. Topics covered are database transactions, callbacks, unit testing and caching." From the article: "In Rolling with Ruby on Rails, I barely scratched the surface of what you can do with Ruby on Rails. I didn't talk about data validation or database transactions, and I did not mention callbacks, unit testing, or caching. There was hardly a mention of the many helpers that Rails includes to make your life easier. I can't really do justice to all of these topics in the space of this article, but I will go into details on some of them and present a brief overview of the rest, with links to more detailed information."
Python and Perl not only differ in syntax, but also aim at completely different niches.
You're not really supposed to write big programs in Perl -- Perl is better suited for short tasks, anything that includes heavy string parsing and/or sysadmin chores.
[evil Perl zealot hat on] Python, on the other hand, serves as a poor excuse for a "real" language aimed for apps longer than several screenfuls of code -- but, it loses because of [XXXXX]. It's also likely to give you Cobol fingers.
In the above, [XXXXX] stands for the real arguments against Python. They were censored out to keep this post within the Holy Wars traditions -- meaningful arguments are not allowed.
The creatures outside looked from Alt-Right to Antifa; but already it was impossible to say which was which.
While I'm not one to cast doubt needlessly on new, different ideas, I must admit that while the Ruby on Rails tutorial was spectacularly simple and fast, the fact is that when I decided to move from toy to trying to implement it, I encountered a number of problems.
First, the database that I hooked this framework to was not empty originally. After hooking the framework to that db, the data disappeared...I should repeat that, my data disappeared without my explicit instruction to destroy the data!.
Second, getting this running on linux was problematic because the tutorial was strictly for Windows and thus missed a few bits about linux (not really the author's fault since he admitted that linux takes more work).
I should be honest and say that after I discovered that RoR was truncating my database every time I tried to use it (without notifying me of that fact), I ran away in horror. I now use Zope and won't go back to RoR.
