This illustrates the purpose of the block for `link_to_if` and
`link_to_unless` helper methods.
It should help to prevent further mistakes like #19844.

😓
The block is not supposed to be passed to `link_to`. It's used for a
customized behavior of the `condtion = false` case. The docs
illustrate that like so:
```
<%=
link_to_if(@current_user.nil?, "Login", { controller: "sessions", action: "new" }) do
link_to(@current_user.login, { controller: "accounts", action: "show", id: @current_user })
end
%>
```
The documentation previously stated that calling `translate(".foo")` was
equivalent to calling `I18n.translate("people.index.foo")` which is
incorrect due to the various other functions of the `translate` view
helper. This has been fixed.
Additionally, a note about forcing the view helper to re-raise
exceptions was added to the section detailing the handling of missing
translations.
Other cleanup includes:
* Consistent formatting of code
* Stop indenting bulleted list as a code sample
* Tighten some of the language
* Wrap at 80 characters.
Running Action View test case currently printing out this warning:
lib/mathn.rb is deprecated
This should silence the warning since we really want to require this
file in this test.
4.2.1 introduced a change to the way `translate`/`t` works with an
option of `default: [[]]`. In 4.2.0, this would give a default value of
`[]`, but in 4.2.1, it leads to a missing translation.
`default: [[]]` is again allowed for cases where a default of `[]` is
needed.
This addresses GitHub issue 19640.
https://github.com/ruby/ruby/pull/579 - there is a new optimization
since ruby 2.2
Previously regexp patterns were faster (since a string was converted to
regexp underneath anyway). But now string patterns are faster and
better reflect the purpose.
Benchmark.ips do |bm|
bm.report('regexp') { 'this is ::a random string'.gsub(/::/, '/') }
bm.report('string') { 'this is ::a random string'.gsub('::', '/') }
bm.compare!
end
# string: 753724.4 i/s
# regexp: 501443.1 i/s - 1.50x slower
The previous change 92a3c8dcdf174dab5e8759031b6bbe6cd891fe3c improved
this example, but calling .create + #valid? ends up running validations
twice, and we don't want to showcase that.
Lets use the normal use case of building a new object and calling #save
on it, which is what a basic scaffold with Active Record does.
