As a result of all of the refactoring that's been done, it's now
possible for us to define a public API to allow users to specify
behavior. This is an initial implementation so that I can work off of it
in smaller pieces for additional features/refactorings.
The current behavior will continue to stay the same, though I'd like to
refactor towards the automatic schema detection being built off of this
API, and add the ability to opt out of automatic schema detection.
Use cases:
- We can deprecate a lot of the edge cases around types, now that there
is an alternate path for users who wish to maintain the same behavior.
- I intend to refactor serialized columns to be built on top of this
API.
- Gem and library maintainers are able to interact with `ActiveRecord`
at a slightly lower level in a more stable way.
- Interesting ability to reverse the work flow of adding to the schema.
Model can become the single source of truth for the structure. We can
compare that to what the database says the schema is, diff them, and
generate a migration.
Now the internal reflections will hold a reference to its public
representation, so when the outside world calls `Account.reflection` we
can build a list of public reflections.
Simplifies the code slightly, isolates non-nil non-range values into a
single array, which will make it easier to do things like apply type
casting to them in the future.
Unlike the outer `rescue`, this one is much more precise about what we
want to handle: a connection failure (`Dalli::RingError`) is not
relevant to what we're testing here. But other Dalli errors may well be
indicating an actual problem.
This is not a security issue since this page is not present in
production and user have to type something in the field but is better to
escape the input.
The intention is to eventually remove `column` from the arguments list
both for `quote` and for `type_cast` entirely. This is the first step
to that end.
Let's say we just ran:
```
$ rails g migrate add_click_to_issue_assignment
```
We will get an error that looks like:
```
Could not find generator migrate.
```
This patch adds all existing migrations to the output to make it easier for a developer to find a valid migration.
```
Could not find generator "migrate". Please select a valid generator:
Rails:
assets
controller
generator
helper
integration_test
mailer
migration
model
resource
scaffold
scaffold_controller
task
```
It would be nice to do some spelling detection and suggest alternatives, but for now this should help.
It appears that the only time that `quote` is called with a column,
but without first calling `type_cast` is when where is called with an
array. My previous pull request broke this behavior, without failing
tests. This adds a test for the only case I can think of that exercises
the `if column.type == :integer` branch of `quote` effectively.
`yield` was missing in #with_dup, due to which 57 assertions were not running
in real, and all tests were passing by default.
Error was introduced in commit - 31ceb5e.
