How do you delete an ActiveRecord object?
I looked at Active Record Querying and it does not have anything on deleting that I can see.
Delete by id
,
Delete the current object like: user.remove
,
Can you delete based on a where
clause?
It's destroy
and destroy_all
methods, like
user.destroy
User.find(15).destroy
User.destroy(15)
User.where(age: 20).destroy_all
User.destroy_all(age: 20)
Alternatively you can use delete
and delete_all
which won't enforce :before_destroy
and :after_destroy
callbacks or any dependent association options.
User.delete_all(condition: 'value')
will allow you to delete records without a primary key
Note: from @hammady's comment, user.destroy
won't work if User model has no primary key.
Note 2: From @pavel-chuchuva's comment, destroy_all
with conditions and delete_all
with conditions has been deprecated in Rails 5.1 - see guides.rubyonrails.org/5_1_release_notes.html
