Question: Let's suppose I have a table called 'user\_products' and a corresponding model called UserProduct in my Rails application. I also have a field called 'is\_temporary' in my table. Now suppose I want to run a query like this but using the ActiveRecord abstraction layer:

```
UPDATE user_products SET is_temporary = false WHERE user_id = 12345;

```

Is there a way I can do this using ActiveRecord? Maybe something along the lines of

```
UserProduct.find_by_user_id(12345).update_attributes(:is_temporary => false)

```

I'd like only one query to be run for this to happen.

Answer: 
```
UserProduct.update_all({:is_temporary => false}, {:user_id => 12345})

```
This is an old post. I updated this in case someone checks it :) (Rails 4)

```
DEPRECATION: Relation#update_all with conditions is deprecated. Please use Item.where(color: 'red').update_all(...) rather than Item.update_all(..., color: 'red').

```

So the query will be 

```
UserProduct.where(:user_id => 12345).update_all(:is_temporary => false)

```

Cheers
