They're Rails Guides, so obviously we're talking about Rails Form Helpers.
Also, 'helpers' should be capitalized.
|
| |
|
|
| |
It's obvious that this is a guide, and none of the other guides say 'A Guide to'.

It's obvious that the guide is based on this version of Rails, and may not be backwards compatible.

Talked with @fxn about this. Bullet points should have periods at the ends.

The wording of these was a bit off, so I fixed them.

The proper name, as per the documentation guides, is 'Active Record.' I've
updated several references to it as 'ActiveRecord'.

Most of the guides have a few simple sentences describing what they will show
you at the top. This one had a few big paragraphs. I've moved those paragraphs
down to an introductory one, and written a new smaller one for the introduction.
This makes this guide more consistent with the others.

This is based on Rails 4, not Rails 3.2.

Clarification to ActiveRecord Validations Doc in 7.2 Custom Methods
|
| |/
|
| |
In the expiration_date_cannot_be_in_the_past validation method, use `expiration_date.present?` instead of the double negative `!expiration_date.blank?`. Also join the comparisons with `&&` instead of `and`, which could cause unintended consequences.

* No need to give a simple example, as we have a
partial that we create in the blog app

* Rails generate model Post ______ creates the
attr_accessible line for you for any fields
you specify. Changed the section to describe
what this line in the model does.

Was surprising found that this example doesn't work:
scope :api do
resources :users
end
and the right form to use it is:
scope 'api' do
resources :users
end
I think this should work similary as `namespace` where both are allowed.
These two are equivalent:
namespace :api do
resources :users
end
namespace 'api' do
resources :user
end

Since now these objects are not cached anymore, there's no need to have
these private methods, just instantiate each of them in the necessary
place.

Follow up of the discussion from the original merge commit:

We want to avoid people's mistakes with methods like count and sum when
called with a block, that can easily lead to code performing poorly and
that could be way better written with a db query.
Please check the discussion there for more background.

Since edd94cee9af1688dd036fc58fd405adb30a5e0da, CollectionProxy
delegates all calculation methods - except count - to the scope,
which does basically what this method was doing, but since we're
delegating from the proxy, the association method was never called.

| | | | |
To perform a sum calculation over the array of elements, use to_a.sum(&block).
Please check the discussion in f9cb645dfcb5cc89f59d2f8b58a019486c828c73
for more context.
