Install
=======

```ruby
gem 'where_lower'
```

Usage
=====
Supports `String`, `Array`, `Range`  
Values in `Array` and `Range` will be converted to `String` and then `downcase`  
Other types will not be touched

```ruby
SomeActiveRecordClass.where_lower(attribute1: 'AbC', attribute2: ['stRing', 123, :symBol], attribute3: ('AA'..'AZ'))
```

Since `0.3.0`  
You can pass a nested hash (1 level deep only) for association condition
```ruby
record.association_records.where_lower(association_table: {association_column: value})
```

You can also add table name in key if you are using it with association  
I don't plan to support any "smart" table guessing though
```ruby
record.association_records.where_lower('association_table.association_column' => value)
```
