SBFactory – парсер контента, программа для наполнения интернет магазинов 10 Ruby on Rails Best Practices If you’re new to Ruby on Rails, one of the most daunting aspects is knowing what’s the preferred way of accomplishing a given task. While a lot of techniques and libraries have come and gone as the community’s preferred way of doing something, there are some best practices that remain, and can lead to writing the cleanest, most secure and maintainable Rails code possible. Listed here today are ten of the most popular and useful best practices you can use as a Ruby developer. Fat Model, Skinny Controller Arguably one of the most important ways to write clear and concise code in Ruby on Rails, the motto “Fat Model, Skinny Controller” refers to how the M and C parts of MVC ideally work together. Namely, any non-response-related logic should go in the model, ideally in a nice, testable method. Let’s look at a simple example. You can change it to this: Then, you can move the logic to your post model, where it might look like this: Reusable Scopes and Relations And in Rails 2: Virtual Attributes

Никаких развлечений — клубов, алкоголя, девочек и всего прочего, только аналитика, парсинг, оптимизация. Но самое грусное в том, что после того как несколько бессонных ночей что то делаешь, в понедельник снова возникает ощущение того, что ничего не делал. В этом плане я даже немного завидую чувакам, работающим на стройке и таскающим кирпичи. Как я уже сказал все выходные я батрачил над компом, а точнее парсил, тестил и снова парсил. Немного выдержки с офф сайта ботмастера: Hrefer — программа, предназначенная для поиска новых ссылок на форумы, гостевые книги, блоги, Wiki и т.п. В общем вот такая полезная программа. В последних версиях хрефера появилась довольно интересная фича парсинга нескольких поисковых систем: На самом деле эту функцию я опробовал только вчера, работает, больше сказать нечего.

Learn It often feels like "best practices" have a shelf-life of a few months before being replaced by better ideas. Between Rails’ constant changes and a never-ending stream of new gems and philosophies, it’s a real challenge to keep up with the state of the art. Stay on top of it by reading the source of the Learn app itself, watching the thoughtbot team contribute to it, reading our books (which also come with high quality source code), and watching screencasts on vim, development tools, and more.
How to capture iPad HTTP traffic on a PC without spending a dime January 7, 2012By Keith Sparkjoy Inspired by an article showing how to capture iPad (any iOS device, actually) traffic using a Mac, this morning I set up my iPad so that I could sniff its network traffic using my favorite HTTP debugger, Fiddler2. It’s remarkably simple to do. Note that this technique assumes that your PC is on the same IP subnet as your iPad. Step 1. Step 2. Step 3: On your PC, run ipconfig from a command prompt to discover your PC’s IP address (mine is 192.168.1.102 in the picture below). Step 4. Step 5: Make a note of your current HTTP Proxy setting (it’s usually set to Off by default). You’re all set! Important!

It’s YOUR career. Lead it! « Testastic Microsoft’s review model is an odd beast. Some things about it I adore, some things about it I abhor, and some things that just don’t make sense to me. Why *do* we go through our “midyear” discussion in March and then write up our Annual reviews in June (3 mos later), then get our reviews back 3 months later? On which review are we supposed to take credit for the awesome things we did from that June to September? This post is not about complaining about the review system. But wanna hear something really neat? These same guys proved that promoting the most competent people from the lower levels up is not as successful of a strategy as alternating between the Best and Worst when promoting. Let that soak in. That tweaks my noodle a bit, but I’ve seen situations like this. He was now competent in the position he was in. This time of year is typically where all employees are done hearing their reviews (I hope so!!!) You need to find a product that will capture your heart. Need more to read?

SchmidtHappens | Evaluating Different Ruby and Rails Versions with RVM If you've ever had to test an application that you are building with different versions of Ruby or Rails then you know how frustrating it can be. RVM aims to erase that frustration by making it incredibly easy to install multiple versions on the same development machine. The first thing that you will need to do is install RVM. To do this open a terminal and enter in the following command (please note, you will need to make sure you have git installed): bash < <(curl -s Once the install finishes you will be instructed on how you can update your .bash_profile file with a load path to the rvm executable.
