Hi,
The validation function returns {error, [ErrorMessages]}
What I do is that I receive it in {error,ErrorList}
I think this is what makes ErrorList a list.
I think what you are doing is that you are receiving it as
{error,[ErrorList]}
and then doing a {json,[{error,ErrorList}]}
This would work fine if you knew for sure there was only one validation
error. But when you have more than one validation errors then I think this
code will break.
In my case, I can get more than one validation errors.
Hence, I have to receive it as a list - {error,ErrorList}
But if I directly json it, I get an array of numbers in output.
So, I instead do {json, [{error,list_to_binary(ErrorList)}]}
This works in my case, giving a string json output.
What also works is this: {json, [{error,io_lib:write_string(ErrorList)}]}
In the previous mail I had also mentioned unicode:character_to_binary. That
however does not seem to work in case of a list of more than one error
strings so that was incorrect.
Please forgive me if I misunderstood you - I am new to Chicago Boss (and
Erlang) :)
Thanks
Jitin
