Strict mode can't be used with coercion disabled

[valscion]

When I use :strict => true mode together with :coerce => false, I would expect to receive errors when my input is not of the type defined with attribute method. What happens, though, is that my input is set as-is and no error is thrown.

Is this intended behavior, that strict: true has no effect when coercion is disabled? If it is, I believe documentation needs to be updated to reflect this.

The code I used to test this is:

class BlogPost
  include Virtus.model(strict: true, coerce: false)
  attribute :slug, String
end

Tested in console:

[1] test »  post = BlogPost.new(slug: {})
=> #<BlogPost:0x007f97d3d469e0 @slug={}>
[2] test »  post.slug
=> {}

Expected outcome was to get an error as strict mode was in use.

Currently strict mode is designed to work with coercions. I agree this should be documented though. I also started wondering if maybe I should change it so that it would raise also when coercion is turned off.

I'll think about this a bit more.

What about if an error would be thrown every time the given attribute was not of the type specified with attribute :name, <type> when coercion is disabled? An example:

class BlogPost
  include Virtus.model(strict: true, coerce: false)
  attribute :slug, String
end

# Error thrown:
BlogPost.new(slug: 2)
BlogPost.new(slug: {})

# No error
BlogPost.new(slug: "foo")

I think it makes sense, just making strict even stricter when it can't fall back to coercion.

@solnic One word: morpher :D

This is concerned with what we want to do. Not how. So morpher is kinda irrelevant here.

@solnic I just try to motivate myself into more OSS time, dont ruin this :D Sorry for the noise BTW.

This isn't noise no worries. It also motivates me to finally start working on integrating morpher. Otoh rom comes first so virtus has to wait.
