Validations

[Torsten Rüger]

Moi,

so as a newbie who was just going to move to datamapper, i am confused about the rails-4 and validations.

My app used paperclip and devise (though that is not written in stone) and so i found dm versions. But especially dm-devise says not to mix with dm-validations.

dm-validations are said to be superfluous and even dangerous as the dm-rails provides ActiveModel validations (indirectly)

Everything pointing towards not to use dm-validations, except dm-paperclip depends on it. 

Now i'm having troubles imagining that i would be the only one to use paperclip in a rails app, so what gives, where is my mistake ?

Any help (also link to paperclip alternatives) appreciated.
