Hello and welcome to this lecture.

2
00:00:03,030 --> 00:00:09,220
In this lecture I'll be explaining what Ruby on Rails is.

3
00:00:10,000 --> 00:00:11,700
What is reals.

4
00:00:11,800 --> 00:00:18,040
Ruby on Rails is also referred to has rails for short what is rails.

5
00:00:18,220 --> 00:00:28,660
Rails is basically a web application development frame work so it is a frame work.

6
00:00:28,660 --> 00:00:30,970
What is the framework meant for it.

7
00:00:30,970 --> 00:00:40,660
What basically is a scaffold that you can build applications around so you can look heavy like a framework.

8
00:00:40,840 --> 00:00:51,340
Physically provides some BS functionality which you can use and the extend to make more complex applications

9
00:00:51,490 --> 00:01:00,020
from there are different types of framework for different types of programming languages.

10
00:01:00,070 --> 00:01:09,880
Rails is written in the Ruby programming Lanke it is designed to make programming web application a

11
00:01:09,880 --> 00:01:11,200
lot easier.

12
00:01:11,290 --> 00:01:13,670
Unal so enjoyable.

13
00:01:14,800 --> 00:01:22,840
Rails also makes assumptions on what developers need to get started.

14
00:01:22,940 --> 00:01:27,970
So it is basically a kind of pin year Ted software.

15
00:01:27,970 --> 00:01:36,040
It has its own opinions so it makes the assumptions that there is a best way to do things and it's designed

16
00:01:36,040 --> 00:01:39,840
to encourage people to do things that way.

17
00:01:40,030 --> 00:01:44,450
In some cases it may also discourage the alternative.

18
00:01:44,590 --> 00:01:47,950
If he notice that you're trying to do things in a wrong way.

19
00:01:48,520 --> 00:01:56,750
So if you do things the framework has advice you to do it should increase your productivity.

20
00:01:57,130 --> 00:02:06,010
Rails also allows you to write less code and achieve more in composing to a lot of other programming

21
00:02:06,010 --> 00:02:06,800
languages.

22
00:02:06,970 --> 00:02:18,640
Unless all the frameworks rails includes two main philosophies and to make your philosophy or guiding

23
00:02:18,640 --> 00:02:30,310
principles behind rails is try dry physically means dont repeat yourself so dry is a principle of software

24
00:02:30,310 --> 00:02:40,300
development which states that every piece of knowledge must have a single on ambiguous or for a tasty

25
00:02:40,510 --> 00:02:44,420
representation within his system.

26
00:02:44,470 --> 00:02:52,210
So by not writing the same information over an array again how I code is more maintainable more extensible

27
00:02:52,360 --> 00:02:57,920
and less buggy ammi's it contains less errors.

28
00:02:57,940 --> 00:03:07,210
Another guide in principle is Convention all fa configuration rails has opinions about the best way

29
00:03:07,270 --> 00:03:14,740
to do many things in a web application and defaults to this set of conventions he has a set way of doing

30
00:03:14,740 --> 00:03:15,770
things.

31
00:03:15,820 --> 00:03:21,990
So if you want to do things g is in the frame what he tool guy do the best way.

32
00:03:22,210 --> 00:03:25,020
So by doing that you save a lot of hassle.

33
00:03:25,120 --> 00:03:29,260
A lot of time and it also makes you more productive.

34
00:03:29,260 --> 00:03:37,720
There are other frameworks available to develop in the Ruby program alone won't buy rails is simos commercially

35
00:03:37,720 --> 00:03:46,030
used and done also most popular off the rails or the Ruby on Rails framework or frameworks used to develop

36
00:03:46,060 --> 00:03:50,410
applications in Ruby Ruby programming language.

37
00:03:50,440 --> 00:03:54,490
That's it for this lecture on the introduction to rails.

38
00:03:54,490 --> 00:03:55,660
Thanks for watching.

39
00:03:55,660 --> 00:03:56,600
Bye for now.
