A lot of warnings like 'warning: the variable "var_name" is unsafe as it has been set inside a case/cond/receive/if/&&/||.'

After upgrading to elixir 1.3 I have faced a lot of warnings! Here are the ones coming from ex_admin:

warning: the variable "controller_route" is unsafe as it has been set inside a case/cond/receive/if/&&/||. Please explicitly return the variable value instead. For example:

case int do
  1 -> atom = :one
  2 -> atom = :two
end

should be written as

atom =
  case int do
    1 -> :one
    2 -> :two
  end

Unsafe variable found at: lib/ex_admin/register.ex:184

warning: the variable "resources" is unsafe as it has been set inside a case/cond/receive/if/&&/||. Please explicitly return the variable value instead. For example:

case int do
  1 -> atom = :one
  2 -> atom = :two
end

should be written as

atom =
  case int do
    1 -> :one
    2 -> :two
  end

Most of this stuff has been fixed on my github master branch. I have been waiting to push a new hex release until I get more of the new ecto2 stuff finished.

There's still one left at

I'm running on master and the docs here: https://github.com/smpallen99/ex_admin/blob/880e511cf3e67081cd727b809eb115eb31a57966/lib/ex_admin/form.ex#L145 show and example that produces compile warnings like this. Is there another way to do conditional rendering? Or, alternatively, add a class to an inputs call?
