Ruby on Rails Web Services and Integration with MongoDB

I have to warn that the assignments are quite lengthy but you will walk out learning a lot on Ruby on Rails, MongoDB and Web Services.

Overall this is a great course with a lot discussion on MongoDB and using Ruby on Rails to build web services.

5 start rating from me Very easy to understand the lectures and is taught by a professor who is well versed with the concepts.I recommend this course 100% 非常好的课程，难度适中，作业有一定挑战，但是遇到问题仔细查阅论坛基本都能够解决，感谢老师的耐心解答 I didn't find it helpful that all the code was simply given to us and we kind of had to figure out what it did.

I would recommend this course to anybody wanting to learn how to develop web apps and api web services using Rails with MongoDB as the backend.

But it was good to learn about MongoDB and ROR.

I am a full-stack developer working mainly with Ruby on Rails.I took this course to learn about MongoDB and how it can be used with Rails, as well as to pick up certain aspects of Rails that I have not been using as much (like JBuilder)The materials and assignments are very detailed, which shows that a lot of effort has gone into them.

I spent a lot of time on the assignments.

Just be prepared to dedicate a lot of time each week.

Also, the I think that the web services coverage is very poor and needs to be improved.

The material was was too much for the estimated time given to spend on the course per week.

The assignments are poorly written and demand too much Ruby expertise for a course meant for Ruby novices.

As the other user said, the assignments are hard but it is worth it.

But it was worth it.

But as a whole this course is great - it offers a different look at database and this is the only course that talks about web services rather than web apps in this specialization.

It really got me thinking about all the types of web apps I could make.

There are entries in the db seed data that cause trouble, leading to intensive debugging and modification of given files that require a much more experienced programmer to figure out.

I spent more time searching google for information than I did the lecture videos because A. the lecture videos are not named or indexed in such a way as to make it easy to figure out which video to rewatch and B. in many cases the particular thing I was trying to do wasn't covered at all.

I can only imagine how will my skill-set look after next two courses and final capstone project.

John Hopkins should be embarrassed that their name is associated with the pedagogical malpractice that is this specialization series.Foolishly, I paid for the entire specialization up front and Coursera refuses to refund me for the remaining two courses.

The first two courses were great, but this one goes too far into the inner workings of MongoDB which is something I have no interest in.

The first two weeks were fairly boring as they are all about MongoDB.

So in spite of the hard work I am happy that I stayed in there to the end.
