| Subject: | args options with a non default constructor |
HI Thomas,
I am trying to use Catalyst::Model::Adaptor with Mongoose where I do
use base 'Catalyst::Model::Adaptor';
__PACKAGE__->config(
class => 'Mongoose',
constructor => 'db',
args => { 'db_name'=> 'medapp' }
);
However with the current code it fails:
Couldn't load class (MedApp) because: Couldn't instantiate component
"MedApp::Model::Mongoose", "Attribute (name) does not pass the type
constraint because: Validation failed for 'Str' with value

As you can see the Base is sending a HASH ref as a parameter rather then
converting it to a list. I traced the problem to the mangle_parameters
function:
https://github.com/kthakore/catalyst-model-adaptor/commit/24284bb699605548fd7c55bb17c59847aab0a5c0
And I fixed it as it was mentioned in the docs for
Catalyst::Model::Adaptor. I have forked and patched the repo and pushed
a pull request. Please consider accepting it.
