# Remove The Default Value On A Column
|
|
|
|
You have a column on one of your database tables with a default value. You'd
|
|
like to remove the default value. Removing the default is the same as
|
|
setting it to `nil`. You can do this with the ActiveRecord DSL using the
|
|
`change_column_default` method.
|
|
|
|
```ruby
|
|
def change
|
|
change_column_default :users, :age, nil
|
|
end
|
|
```
|
|
|
|
See [the
|
|
docs](http://api.rubyonrails.org/classes/ActiveRecord/ConnectionAdapters/SchemaStatements.html#method-i-change_column_default)
|
|
for more details.
