Removing the limit from the PG and SQLite adapter solves the issue.
MySQL is still affected by the issue.

There is no reason for the PG adapter to have a default limit of 255 on :string
columns. See this snippet from the PG docs:
Tip: There is no performance difference among these three types, apart
from increased storage space when using the blank-padded type, and a
few extra CPU cycles to check the length when storing into a
length-constrained column. While character(n) has performance
advantages in some other database systems, there is no such advantage
in PostgreSQL; in fact character(n) is usually the slowest of the
three because of its additional storage costs. In most situations text
or character varying should be used instead.

CollectionProxy should be able to reuse the behavior (methods) of its parent class,
but with its own state. This change allows CollectionProxy to use the arel object
corresponding to its association's scope.

Fix error when using `with_options` with lambda.

It was causing error when using `with_options` passing a lambda as its
last argument.
class User < ActiveRecord::Base
with_options dependent: :destroy do |assoc|
assoc.has_many :profiles, -> { where(active: true) }
end
end
It was happening because the `option_merger` was taking the last
argument and checking if it was a Hash. This breaks the HasMany usage,
because its last argument can be a Hash or a Proc.
As the behavior described in this test:
https://github.com/rails/rails/blob/master/activesupport/test/option_merger_test.rb#L69
the method will only accept the lambda, this way it will keep the expected behavior. See 9eaa0a34

change to the absolute-path interpretation in 4.2.

sqlite3:relative/path
sqlite3:/full/path

This is all about the case where we have a `DATABASE_URL`, and we have a
`database.yml` present, but the latter doesn't contain the key we're
looking for.
If the key is a symbol, we'll always connect to `DATABASE_URL`, per the
new behaviour in 283a2edec2f8ccdf90fb58025608f02a63948fa0.
If the key is a string, on the other hand, it should always be a URL:
the ability to specify a name not present in `database.yml` is new in
this version of Rails, and that ability does not stretch to the
deprecated use of a string in place of a symbol.
Uncovered by @guilleiguaran while investigating #14495 -- this actually
may be related to the original report, but we don't have enough info to
confirm.

Also do not use transactional fixtures. We drop the type and the
table after every run, so there is nothing for the transaction to clean up.
|

Creating and dropping similar tables within the same connection causes postgresql to look up old values in the cache of tables which have already been dropped.

I ran the whole test suite and compared the old to the new types.
Following is the list of types that did change with this patch:
```
DIFFERENT TYPE FOR mood: NEW: enum, BEFORE:
DIFFERENT TYPE FOR floatrange: NEW: floatrange, BEFORE: float
```
The `floatrange` is a custom type. The old type `float` was simply a coincidence
form the name `floatrange` and our type-guessing.

Fix delete all to not produce sql in statement

When delete_all is run on a CollectionProxy and has a
dependency of delete_all the SQL that is produced has an IN
statement. (DELETE FROM `associated_model` where `associated_model`
.`parent_id` = 1 AND `associated_model`.`id` IN (1, 2, 3...)).
This only happens if the association is not loaded (both loaded
and non-loaded delete_all should behave the same. This is a huge
problem when it comes to deleting many records because the query
becomes very slow. Instead the SQL produced should be (DELETE FROM
`assoicated_model` where `associated_model`.`parent_model_id`=1).
I fixed this by making sure the check for loaded and destroy also
makes sure that the dependent is not delete_all, so the conditional
goes to the else and deletes the records directly without the IN
statement.
|
| | | | | |
| | | | | |
| | | | | |
| | | | | |
| | | | | |
| | | | | | |
delete_all sql if an association is not loaded should behave
the same as if the association is loaded. This test ensures
the SQL statements are exactly the same.

The new method relies on AR::Associations::Association knowing about both reflection and a model class.
AR::Base#association now raises a descriptive error when trying to access non-existent associations. Previously it would blow up with a confusing NoMethodError: undefined method `association_class' for nil:NilClass.
