# Get The Column Names For A Model
|
|
|
|
An `ActiveRecord` model is backed by a table in your application's database. We
|
|
can get the column names for a backing table with `ActiveRecord`s help using
|
|
the `.column_names` method.
|
|
|
|
```ruby
|
|
> Book.column_names
|
|
=> ["id", "title", "publication_year", "created_at", "updated_at", "author_id", "genre"]
|
|
```
|
|
|
|
Any `ActiveRecord` model will have access to this class method.
|
|
|
|
See [the
|
|
docs](https://devdocs.io/rails~5.2/activerecord/modelschema/classmethods#method-i-column_names)
|
|
for more details.
