Move mysql2 test for when adapter will be loaded
|
| |
| |
| |
| |
| |
| | |
When run with only the Mysql adapter, we get this failure: https://travis-ci.org/rails/rails/jobs/15937907#L2416
Porting the test over to only run when mysql2 is loaded
|
|/ |
|
|
|
| |
Building on the work of #13427 this PR adds a helpful error message to the adapters: mysql, mysql2, and sqlite3

Do not store production information in .yml files

This commit also cleans up the rake tasks that were checking
for DATABASE_URL in different places.
In fact, it would be nice to deprecate DATABASE_URL usage in the long
term, considering the direction we are moving of allowing those in .yml
files.

Always pass in the column for quote_bound_value and quote using it in
case it exists there.

The code uses these checks in several places to know what to do with a
particular column, for instance AR attribute query methods has a branch
like this:
if column.number?
!value.zero?
end
This should never be true for array columns, since it would be the same
as running [].zero?, which results in a NoMethodError exception.
Fixing this by ensuring that array columns in PostgreSQL never return
true for number?/text? checks.
Since most of the array support was based on the postgres_ext lib, it's
worth noting it does the same thing for numeric array columns too:
https://github.com/dockyard/postgres_ext/blob/v1.0.0/lib/postgres_ext/active_record/connection_adapters/postgres_adapter.rb#L72
This extended the same logic for text columns to ensure consistency.

Currently if you attempt to use a database that does not exist you get an error:
```
PG::ConnectionBad FATAL: database "db_error" does not exist
```
The solution is easy, create and migrate your database however new developers may not know these commands by memory. Instead of requiring the developer to search for a solution, tell them how to fix the problem in the error message:
```
ActiveRecord::NoDatabase: FATAL: database "db_error" does not exist
Run `$ bin/rake db:create db:migrate` to create your database
```
Active Record should not know about `rake db:migrate` so this additional information needs to come from the railtie. Potential alternative implementation suggestions are welcome.

modified regex for finding table_name from a multiline sql query in postgresql

Previously, executing an insert SQL in PostgreSQL with a command like this:
insert into articles(
number)
values(
5152
)
would not work because the adapter was unable to extract the correct articles table name.

Change most tests to make use of assert_raise returning the raised
exception rather than relying on a combination of flunk + rescue to
check for exception types/messages.

Fix PostgreSQL range tests on fresh DB
Correcting the name of the table we're creating is self-explanatory.
But we must also move away from the low IDs, because we're not touching the freshly-created primary key sequence; when the time comes, @new_range will be assigned an ID of 1.

The changes in c4044b2 meant the tests would error on a fresh DB.

Create a blacklist to disallow mutator methods to be delegated to Array

This change was necessary because the whitelist wouldn't work.
It would be painful for users trying to update their applications.
This blacklist intent to prevent odd bugs and confusion in code that call mutator
methods directely on the `Relation`.

Default I18n.enforce_available_locales to true
We will default this option to true from now on to ensure users properly handle their list of available locales whenever necessary. This option was added as a security measure and thus Rails will follow it defaulting to secure option.
Also improve the handling of I18n config options in its railtie, taking the new enforce_available_locales option into account, by setting it as the last one in the process. This ensures no other configuration will trigger a deprecation warning due to that setting.

Using the name of an association in `where` previously worked only
if the value was a single `ActiveRecrd::Base` object. e.g.
Post.where(author: Author.first)
Any other values, including `nil`, would cause invalid SQL to be
generated. This change supports arguments in the `where` query
conditions where the key is a `belongs_to` association name and the
value is `nil`, an `Array` of `ActiveRecord::Base` objects, or an
`ActiveRecord::Relation` object.
# Given the Post model
class Post < ActiveRecord::Base
belongs_to :author
end
# nil value finds records where the association is not set
Post.where(author: nil)
# SELECT "posts".* FROM "posts" WHERE "posts"."author_id" IS NULL
# Array values find records where the association foreign key
# matches the ids of the passed ActiveRecord models, resulting
# in the same query as Post.where(author_id: [1,2])
authors_array = [Author.find(1), Author.find(2)]
Post.where(author: authors_array)
# ActiveRecord::Relation values find records using the same
# query as Post.where(author_id: Author.where(last_name: "Emde"))
Post.where(author: Author.where(last_name: "Emde"))
Polymorphic `belongs_to` associations will continue to be handled
appropriately, with the polymorphic `association_type` field added
to the query to match the base class of the value. This feature
previously only worked when the value was a single `ActveRecord::Base`.
class Post < ActiveRecord::Base
belongs_to :author, polymorphic: true
end
Post.where(author: Author.where(last_name: "Emde"))
# Generates a query similar to:
Post.where(author_id: Author.where(last_name: "Emde"), author_type: "Author")

`test_with_limiting_with_custom_select`.
The query's result was built in a hash with column name as key, if the
result have a duplicated column name the last value was
overriding the first one.
