Learning Ruby on Rails

I have been reading agile web development with rails over the past few days.

Before reading a book, I thought of the following questions, which need to be found in the book:

1. How to input validate, such as a required, number, date, range, and general logic check?
2. How can I change the default input format? For example, the default format of datetime is yyyy-mm-dd hh-mm. How to Use yyyy-mm-dd?
3. How to encrypt password settings?
4. How to Implement the drop-down selection box?
5. Is there a masterpage?
6. How to Use session and cookie?
7. How to migrate pages?
8. How to Implement transaction?
9. How to implement unit test? What about performance test?
10. How does the active record process multiple tables?
11. Is there Ajax?
12. How to use web service?
13. How to Use cache?

After reading this book for four days, I finally finished reading this book :)

In addition to question 5, you can also find the answer.

 

The general feeling after reading the book is that rails has changed our development model,

You can focus on a more abstract level and quickly develop a prototype for iterative development. In addition, Dynamic Language performance is really cool.
