hey folks, if I used
.default(false) for one of the attributes, and I passed nil it convert it to the default value used
why not throwing an error?
Is there a way to define multiple constructors for different data sources on a single struct? E.g. I (probably) want to use the
schemaconstructor when instantiating my struct from the database, but want to use strict_with_defaults everywhere else
I have the feeling that dry-rb wants me to have structs that are specific to the datasources I am pulling their content from, but since I'm refactoring an old codebase here, it would be a ton of work
@untitaker there is
Struct.constructor that takes a block
@flash-gordon I forgot to thank you for that, that seems good.
other question: what's up with this? https://gist.github.com/untitaker/a41afabcdf608c68f86cdbe854f9b905 I would've assumed it raises a validation error, but instead it raises NoMethodError
it works fine for valid input
@untitaker what's the stacktrace of the error? :)
@flash-gordon ^
@untitaker something's wrong there, could you file an issue to dry-struct with that example?^
Hello all!
@flash-gordon, I would like to ask you about your example from your presentation:

Events::PasswordChanged class is kind of Events::Updatemodule Events
class PasswordChanged < Dry::Struct

Updated = PasswordChanged | EmailChanged

Events::Update[event] <- this either will raise an error or return the value back
Thanks! I found
Events::Updated.valid?(event) also.
or you can use
try if you don't want to raise an exception, although structs are supposed to be used with valid input where if anything doesn't match the format raises an exception
right,
valid? is another option
