Errata for Head First Rails

Is "to" here extra that has to be removed? We need a set of pre-written code "to" that will form the foundation of the web application.

you will probably still need these "three" things for your deployed application. Isn't it supposed to be "four" things? Since we have four points? Thanks.

In the following: We need a set of pre-written code "to" that will form the foundation of the web application. I think that "to" has to be removed. Thanks.

There are many features built "in to" Rails. Shouldn't it be "into"? Thanks.

There are many features built "in to" Rails. Shouldn't it be "into"? Thanks.

The main reason "these application exists"..... Shouldn't it be "these applications exist"? Thanks.

"It" you want to use another port, such as 8000, run... I think it should be "If". Thanks.

The model code manages how "data is written and read to your database". Shouldn't it be: data is written to and read from your database? Thanks.

'suposed' should be changed to 'supposed'

Note from the Author or Editor:
"bookings are suposed" in the boss' speech bubble should be replaced with "bookings are supposed"

AddPhoneToTickets adds phone to the "ticket" table. I think it should be "tickets"? Thanks.

An 'is' is missing after 'it': "once the code has been generated it the developer's ..."

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

Note from the Author or Editor:
Change "it" to "it's"

Since all the notes contain a "." after them. Do you think "A decimal" has to have a "." (dot) at the end for consistency? Thanks.

Text: ..."If someone asks for for ad#3..." Double word "for for", change to "for". Greetings from Freiburg in lovely Germany

If someone asks for "for" ad..... "for" is repeated twice. Thanks.

The 10th question is in singular form, although it should be in plural. Question in the book is: Why are the templates in a folder called "views/ad" but the controllers are not in "controllers/ad? The correct version is: Why are the templates in a folder called "views/ads" but the controllers are not in "controllers/ads?

Note from the Author or Editor:
"views/ad" should be changed to "views/ads" and "controllers/ad" should be changed to "controllers/ads"

MeBay only "want" a very small amount of..... Shouldn't it be "wants"? Thanks.

missing single quote at end of line: 'show should be 'show'

Note from the Author or Editor:
"you taken a peek" should be "you've taken a peek"

...."you" taken a peek under the hood of Rails.... Shouldn't be there a "have" after you? Thanks.

"...user is asking for /ads/3, ..." should be "...user is asking for /seller/3, ..."

Note from the Author or Editor:
In the intro paragraph on pages 71/72, "/seller/:id" should be "/sellers/:id" In the annotation on page 72 "/ads/3" should be "/sellers/3"

'An index pag.' should be 'An index page'

Note from the Author or Editor:
Annotation on the "All Ads" page should be "An index page."

I think it should be "page". An index "pag". Thanks.

should the following sentence be "Ruby on Rails". (on) INSTEAD OF (or)? Ruby or Rails Thanks.

Should it be "its", instead of "it's" ...It doesn't keep "it's" own copy of an object, it just remembers where they live. Thanks.

I think "the" has to be "a". Is there "the" problem with inserting... Thanks.

Shouldn't it be "puts". With an (s)? ..., Rails already "put" quite a few Thanks.

The <% form for %> tag is missing an underscore. It should be <% form_for %>

Note from the Author or Editor:
"Available" is mis-spelled in the top annotation.

"new html.erb" should be "new.html.erb"

Shouldn't the seconf "of" be removed? ...with a set of hash table "of" values that will be... Thanks.

Note from the Author or Editor:

Shouldn't "That" be "That's"? "That" way, if someone enters a record,..... Thanks.

The class should read"AdsController" and not "AdController"

"requires needs a model object to work." choose one of "requires needs"

Note from the Author or Editor:
Change to "needs"

The magnets offer the choice of "search_string", but in the solution on the next page, the answer is :search_string.

The URL to download the "ready bake code" ends in books/rails. The correct URL ends in books/hfrails.

The paragraph starts with: WIth a model form ... The second letter is capital, should be corrected to: With a model form ...

Note from the Author or Editor:
"WIth" should be "With"

'...the string the user is searching form.' should be '...the string the user is searching for.'

Note from the Author or Editor:
"is searching form" should read "is searching for"

'...no object to with a single...' should be '...no object with a single...'

Note from the Author or Editor:
'...no object to with a single...' should be '...no object with a single...'

"finder for each of it's attributes" it should be "its"

'...and avoid a type security attack...' should be '...and avoid a type of security attack...'

Note from the Author or Editor:
"type security" should be "type of security" in the final annotation.

'Some people are have been leaving...' should be 'Some people have been leaving...'

Note from the Author or Editor:
"Some people are have" should be "Some people have"

"trainer's name need to completed" should be "need to be completed"

Note from the Author or Editor:
Should be: "Trainer's name needs to be completed"

'...on new adds were completed,...' should be '...on new ads were completed,...'

Note from the Author or Editor:
"adds were" should be "ads were"

"Now what happens now if we miss..." Skip ONE of these two "now", so either "Now what happens if we miss..." or "What happens now if we miss..." sounds right to me.

Note from the Author or Editor:
Change to: What happens now if we miss

'Coconut Airways need a booking system' should be 'Coconut Airways needs a booking system'

Note from the Author or Editor:
'Coconut Airways need a booking system' should be 'Coconut Airways needs a booking system'

In the 2nd sentence "Here's the content of our _new_seat.html.erb partial." only the partial file name should be printed in the fixed width font face. So the word "our" in this sentence has been printed in the wrong font face.

'The render call tell Embedded Ruby...' should be 'The render call tells Embedded Ruby...'

Note from the Author or Editor:
'The render call tell Embedded Ruby...' should be 'The render call tells Embedded Ruby...'

The render call "tell" Embedded Ruby to process the partial and include its output at that point in the file. I think "tell" has to be "tells" (With an (s) at the end). Thanks.

"Remove the list to" should be "Remove the link to"

New partial is given name _seat_list.html; thereafter it is referred to as _seat_list.html.erb

Last line ends in "return it to the browser." This should be, "returns it to the browser." (The controller looks...generates...and returns...)

The text, html source fragment and top of the screenshot refer to flight 2, but the seat list shown is for flight 1

In "We can get around this is by giving..." remove the "is".

"The presence of the value in a request show that a request..." 'show' should be 'shows': "The presence of the value in a request shows that a request..."

"But how do we make this the..." should be "But how do we make this..." or "But how do we make the..."

Note from the Author or Editor:
s/be "But how do we make the form work..."

"you might expect that you will need to how to write JavaScript code" should be "you might expect that you will need to know how to write JavaScript code"

"...the HTML in the 'notices' <div/>..." should be "...the HTML in the 'notice' <div/>..." The 'notices' code magnet should be a 'notice' code magnet on page 299.

Note from the Author or Editor:
On page 299 change the instructions on the Code magnets from: ...HTML in the 'notices'... to ...HTML in the 'notice'... Change the 'notices' magnet to 'notice'

"the page object will generate code to updates the notice" should be "the page object will generate code to update the notice"

The heading says "The completed code CAN WILL now do several things" It should be: "The completed code can now do several things"

'...we used Ajax to download new version...' should be '...we used Ajax to download a new version...'

"and you will found several places" should read "and you will find several places"

'...and the XML bulder template...' should be '...and the XML builder template...'

In the 1st paragraph, 3rd line, the word "the" is doubled. Instead of "could probably just remove the the list of incidents..." write "could probably just remove the list of incidents..."

"The people ... figured that ..." In school we learned it should be: "The people ... figured OUT that ..." Please let me know when I am wrong via email instead of silent deleting this submission.

"...our action will need to generated from a partial..." should be "...need to be generated..."

"Once you've clicked on the save button, you're to the cut down..." should read: "Once you've clicked on the save button, you're redirected to the cut down..."

Instead of 'When the map calls the "new" action is sends...' write (the same as on page 371) 'When the map calls the "new" action it sends...'

"...calls all of it's own..." should be "...its..."

"That return true..." should be "That returns true..."

Last question reads: "But we don't have fields for id, created_ad and updated_at fields?" this should read: "But we don't have fields for id, created_ad and updated_at?"

I assume the correction on p. 389 replacing "edit_incident_url" with "edit_incident_path" carries forward to this page too, in both code examples near the bottom of the page.

"Well that works pretty like the new form did." pretty much?

'...harder to reader and...' should be '...harder to read and...'

"Visti us here for details..." should be "Visit..." (?)

How do you make the most out **the** Rails and the Ruby language?

Note from the Author or Editor:
Change text to be: How do you make the most out of Rails and the Ruby language?

"Pretty-print the contents of an array" should be "Pretty-print the contents of a hash"

"That why" should be "That's why"

"These are the used in the RESTful routes in a scaffold application." should be "These are the urls..."

"The third principle... there should __ a well defined..." Missing "be" a well defined...
