Programmers can take advantage of this feature when defining custom
default settings. And, since many CONSUL installations had custom
changes in the `custom/verification/residence.rb` model and those
changes might use regular expressions, we're making it easier to migrate
that code to the new system to define valid postal codes.
We aren't documenting this feature in the description in the admin
section because most administrators don't know what regular expressions
are.
Note that, in order to simplify the setting, we already define the `/\A`
and `\Z/` characters. So, if the custom code had something like
`postal_code =~ /^280/`, the setting would have to be "280*" (without
the quotes) or, in order to comply with a length validation,
"280[0-9]{2}" (without the quotes).
Due to the way Madrid handled postal code validations (see issue 533),
by default we were requiring everyone to validate against the local
census *and* to specify valid postal codes.
This could be useful in some cases, but in other cases, the census
validation will be enough and there'll be no need to manually define the
valid postal codes. Besides, some CONSUL installations are used in
organizations or political parties where the postal code validation
doesn't make sense.
In some countries, postal codes are defined with a dash in the middle,
so we're using a colon to define ranges instead. We could also use two
dots, like in Ruby ranges, but IMHO this would cause typos since people
would enter codes separated with three dots or just one dot.
We weren't using the `be_valid` matcher because we had errors in the
census data.
Removing the `before_validation` callback and using a method to get the
census data instead allows us to stub the `census_data` method in the
tests, and so we can use the `be_valid` matcher instead of calling
`valid?` manually and then checking for errors.
We were inconsistent on this one. I consider it particularly useful when
a method starts with a `return` statement.
In other cases, we probably shouldn't have a guard rule in the middle of
a method in any case, but that's a different refactoring.
We were very inconsistent regarding these rules.
Personally I prefer no empty lines around blocks, clases, etc... as
recommended by the Ruby style guide [1], and they're the default values
in rubocop, so those are the settings I'm applying.
The exception is the `private` access modifier, since we were leaving
empty lines around it most of the time. That's the default rubocop rule
as well. Personally I don't have a strong preference about this one.

Date.new(...) does not take into account the current timezone, while other
parts of the application do. By default always parsing any date with the
default timezone and converting the resulting Time to Date would prevent
this kind of issues
DateTime.parse(...).in_time_zone gives an unexpected result, as the
DateTime.parse(...) will create a DateTime with +0000 time zone and the
`in_time_zone` will modify the DateTime to adjust to the default zone.
Maybe its better explained with an example, using 'Lima' as timezone:
DateTime.parse("2015-01-01")
> Thu, 01 Jan 2015 00:00:00 +0000
DateTime.parse("2015-01-01").in_time_zone
> Wed, 31 Dec 2014 19:00:00 -05 -05:00
And that's not the desired date but the previous day!
Here's a better alternative than the first one. Added a new abstraction level from which are performed both types of census calls, while the logic of those is managed in their own library.
