# `belongs_to` likes a singular name

In Ecto, there is a convenient keyword to represent a relationship between schemas. One of the building blocks is "belongs_to." I found that the name of the association should remain in singular form. 

I asked why this is the case. It seems that the naming is based on convention, but Ecto actually infers the foreign key name from the association name.

```
schema "albums" do
  # field definitions here
  belongs_to :artists, MusicDB.Artist
end  
```
