No target defs

[Xosmond]

Im getting this error:

Error in lib/jennifer/src/jennifer/adapter/base_sql_generator.cr:137: BUG: no target defs

          io << query._raw_select

When I run this command on a amber project:

crystal src/sam.cr -- generate:migration CreateCompanies

Any idea on whats the problem?

Could you provide some of your environment details? Namely crystal version (crystal -v), version of jennifer (shards list), and what DB config you are using?

@Xosmond @z64 yeah, I know the reason. somewhy sometimes (I can't find minimal code that will reproduce this bug) code like next:

class Test
  property var : Array(String)?
  def asd
    @var.not_nil!
  end
end

String.build do |s|
  t = Test.new
  t.var = ["asd"]
  s << v.asd
end

will provide such exception.

@Xosmond Today will commit a fix to the master.

[Xosmond]

Heres the information (running on a MacOS 10.12.6):
Crystal version: Crystal 0.23.1 (2017-10-12) LLVM 4.0.1
Jennifer version 0.4.0 (while shards list show 0.3.4, shards.lock show 0.4.0)

Oh great @imdrasil, I will wait for it then. Thank you for taking care of it. I hope I can learn more crystal to contribute to Jennifer on the future.

@Xosmond try to pull from master branch actually it already should be fixed

[Xosmond]

@imdrasil Yes, you are right, with master branch it works fine. Now I can close this. Good job, Regards.

@Xosmond in few hours I will make new release (0.4.1) so u can switch to normal specifying in shards file

[Xosmond]

@imdrasil Sr, I have some questions about validations (the way is implemented), where can we talk about it?

[imdrasil]

@Xosmond via email (u can find it in my profile). Or if u think that conversation is important or can help someone - create an issue
