Issue #16

[boonya]

Dude, seriously, I have no idea what does this error mean https://travis-ci.org/ets-labs/domain_models/jobs/104227992#L121

@boonya, great job! Thanks!

One thing here here that would be nice to add - add required=False argument for fields.Model and fields.Collection initializers and pass it to the parent initializer call (like it is done for default argument in these fields).

I didn't use **kwargs for the child fields that have overridden initializer and retained default arg obviously defined, because of making easier IDE introspection and autosuggestion when someone will define a field (**kwargs - is easier to maintain, but worse for the end-user).

About the tests failing on 3.2 - it's a travis problem. I checked on our other project - situation is the same. So, no worries.

@rmk135, like this one? a662609

BTW, I have added Travis CI & Coveralls bages into README

[rmk135]

Yeah, like this! Thanks!

Regarding the badges - looks good!

I think that will make it like there https://github.com/ets-labs/dependency_injector/blob/master/README.rst in future.

[boonya]

Of course. In future it will be. I think we will add much more bages ;)

I've added more badges ;) 2e84f1e
