1st paragraph

Error in:

But the downside is that once the code has been generated "it the" developer's responsibility to keep the code up-to-date.

I think "is" has to come in between "it the".

Thanks.

Second point

By a symbol"." we mean a sequence

I think "." has to be ","

Thanks.

chapter 2 in polish

I have bought this book in polish and I am trying to change its for Rails 4 and Ruby 1.9.3 - I have "agile programming ruby on rails 2013 - english", too.
But routing and routes are very difficult for me and I do not know, what should be here:
map. connect '/ads/:id', : controller=> 'ads', :action=> 'show' etc.

In "Agile Programming" there is not something like this.

Is there any more actually version of this book anywhere?

1st paragraph

I just want to note a typo in: <% form for %>

As there should be an "_" between "form" and "for":

<% form_for %>

Thanks.

When updating Controller and the Views for the Create a new item, I get the following error

Couldn't find Ad with ID=create

I had to update the route with the following code

map.connect '/ads/create', :controller=>'ads', :action=>'create'

for ruby to recognize what to do with the create request.

Please let me know if I am doing something wrong. Following this book to a T but this piece really stumped me for a while.

Point (2)

In point (2), there should be a ".".

Form script

Edit form url need to post the id too.
This worked for me:
form_for(@ad,:url=>{:action=>'update', :id=>@ad.id}) do |f|

4th paragraph

Every time one of the validators "fails"....

I think it should be "fail".

Thanks.

The title

Typo:

Coconut Airways "need" a booking system

I think it should be "needs" ---> with an "s"

Thanks.

Last paragraoh

Typo:

The render call "tell".....

I think it should be "tells" ---> With an "s" at the end

Thanks.

Third paragraoh

Typo:

provide the "new" _seat_list. html. erb

I think that "new" has to have a different font type similar to the ordinary text and NOT the file name.

Thanks.

13th line.

"and a symbol mark the exact point" should be "and a symbol will mark the exact point"
