Arel

gistfile1.txt

```
scope :arel, ->(column, predication, *args) { where(arel_table[column].public_send(predication, *args)) }
```

Example usage of the scope:

```
MyModel.arel(:created_at, :lt, 2.days.ago)
```
For all predications, check the documentation or source code.
This scope doesn't break the where chain. This means you can also do:

```
MyModel.custom_scope1.arel(:created_at, :lt, 2.days.ago).arel(:updated_at, :gt, 2.days.ago).custom_scope2
```
