# Read-Only Models
|
|
|
|
Are you in the midst of a big refactoring that is phasing out an
|
|
`ActiveRecord` model? You may not be ready to wipe it from the project, but
|
|
you don't want it accidentally used to create any database records. You
|
|
essentially want your model to be read-only until it is time to actually
|
|
delete it.
|
|
|
|
This can be achieved by adding a `readonly?` method to that model that
|
|
always returns `true`.
|
|
|
|
```ruby
|
|
def readonly?
|
|
true
|
|
end
|
|
```
|
|
|
|
`ActiveRecord`'s underlying persistence methods always check `readonly?`
|
|
before creating or updating any records.
