Rails 4 in Action 1P review notes

r4ia.txt

1.2.4 Scaffolding

binstubs was only introduced later on, so bin/rails makes no sense


Listing 1.16

update(purchase_params) is used instead of update_attributes(params[:purchase])



Chapter 2

Some mentioning of current tools that assist with the tdd process such as guard/debugger/pry could be useful here.



Listing 3.4

assets group is deprecated


Listing 3.5

Text should corresponding to the listing for references to rspec-rails versions (2.13.x)


3.3.3 Applying a stylesheet

custom stylesheet no longer relevant? (according to https://github.com/steveklabnik/ticketee)


Listing 3.9

`visit root_url` (named route in place of string paths) is more idiomatic


Listing 3.11

Some mentioning of the limited scaffold_controller generator (and its various options to exclude generation of specs like --no-controller-specs)
could be useful, either here or later, to make the point that it already comes with useful defaults such as 
set_model and model_params methods.

Or earlier, when scaffold is used for the first and only time (it shows up in the console output)


Listing 3.16

<p> without matching closing tag


Listing 3.17

Effects of strong_parameters should be mentioned here since it is default in Rails 4. 
Expecting a ForbiddenAttributesError here

Listing 3.23

In the Warning box, validates_uniqueness_of is actually a convention from Rails 2 
even though it is equivalent to the current `validates` idiom.

Listing 3.24

Doesn't make sense, the example doesn't have anything to do with projects#new, and mentioning it can only lead to confusion


4.1.1 The Factory Girl

typo: factory_girl_rails
why is factory_girl needed as well?

Listing 4.2 spec/support/factories/project_factory.rb

Inconsistent path, should be spec/factories

4.1.2 Adding a link to a project

5 examples, 2 pending is inconsistent (generated spec files were removed earlier)


Listing 4.9 

Inconsisted factory_girl syntax


5.1.3 Defining a has_many association

index syntax for generated migration has changed


Listing 5.7 Listing 5.7 spec/factories/ticket_factory.rb

Inconsistent: previously spec/support/factories was used


Listing 5.10 Listing 5.10 update action, TicketsController

why leave out the method header? `def update; end`

6.1 Authentication Basics

user.authentication should be user.authenticate
Missing labels for code listings

6.2 Signing Up

name of the spec file (signing_up_spec.rb) is only mentioned much later, needs to be earlier
Missing labels for code listings
what is @ticket.errors doing in user form partial?! 
There should be 19 examples right before "Implemented sign up."
There should be 21 examples right before "Implement profile pages"
NO mention of user_factory.rb!

Significant content needed for user_profile_spec.rb to work is missing:
