Add support for coercion by endpoints with type File #318
Description
If you have a remote method with a parameter that's type: 'file' you receive following error:
"Error: Invalid value for argument 'file' of type 'file': [object Object]. Received type was converted to object.
As far as I understood the error is in function convertToBasicRemotingType in shared-method.js:
function convertToBasicRemotingType(type) {
if (Array.isArray(type)) {
return type.map(convertToBasicRemotingType);
}
if (typeof type === 'object') {
type = type.modelName || type.name;
}
type = String(type).toLowerCase();
switch (type) {
case 'string':
case 'number':
case 'date':
case 'boolean':
case 'buffer':
case 'object':
case 'file':
case 'any':
return type;
case 'array':
return ['any'].map(convertToBasicRemotingType);
default:
// custom types like MyModel
return 'object';
}
}
The type file is supported as a separate type. The problem is that the arg is coming as type object.
My fix at the moment is to use object as arg type or to use a older version where the file type is not supported and becomes default type object.
But i would like to use the correct type: file.
My interface definition:
model.remoteMethod(
'fileUpload',
{
http:{ verb:'Post', source: 'body', path: '/upload/:id'},
description: '',
accepts: [
{arg: 'id', type: 'string', http: { source: 'path' }, required: true},
{arg: 'file', type: 'file', http: { source: 'body' }, required: true},
{arg: 'req', type: 'object', http: {source: 'req'}}
],
returns: {arg: 'res', type: 'object', root:true}
});
Perhaps I am doing something wrong?
