UInt32 mysql column error

[dmatamoroscr]

I'm getting this error when I try to set a column as an UInt32 with null: false
(using it in amber framework with mysql adapter, all in latest versions)

There was a problem expanding macro 'base_mapping'

Code in macro 'draw_mapping'

 3 | base_mapping(true)
     ^
Called macro defined in lib/jennifer/src/jennifer/model/mapping.cr:206:7

 206 | macro base_mapping(strict = true)

Which expanded to:

 > 505 |
 > 506 |               begin
 > 507 |                 __temp_221.as(UInt32)
                         ^
Error: can't cast Nil to UInt32

Relevant model mapping:

  mapping(
    id: Primary32,
    from_ip_num: {type: UInt32, null: false},
    to_ip_num: {type: UInt32, null: false},
  )

I hope you've already found the root cause but otherwise here is my thought. Likrly the reason is that you pass nil to one of your UInt32 field. Unfortunately because of the dynamic nature of mapping system compilation errors may be not very obvious. Please use --error-trace for full log so it'll be easier to debug

@dmatamoroscr do you still need any assistance with your issue?
