Auto ignore properties when Destination Class does not have that property

[rmalveis]

Hi.
I was using this lib, but I'm missing this functionality.
How can I achieve this using current implementation?

Here is a testCase to clarify:

it('should ignore properties on source object missing on destination object type Definition', () => {
            // arrange
            class DestinationType {
                public keep: string = null;
            }

            var fromObject = {
                keep: true,
                remove: true
            };

            var fromKey = '{60D9DB56-D6E1-48FF-9BAC-0805FCAF91B7}';
            var toKey = '{AC6D5B97-9AE3-4267-BD60-A5FED17E541A}';

            automapper.createMap(fromKey, toKey).convertToType(DestinationType);

            // act
            var toObject = automapper.map(fromKey, toKey, fromObject);
            // assert
            expect(toObject).toBeDefined();
            expect(toObject.remove).not.toBeDefined();
        });

(Just adding this test case to your current set it fails).

I didn't waste too much time analyzing and I think I made simple-minded solution, but you can check it and please feel free to make it safer or toggleable...
Can I open a pull request for you with my changes?

In my current working project this feature is essential.

Cheers.

Hi @rmalveis ! Thanks for creating this issue and your PR. I just merged the PR (kudoos for your work!). I am currently developing on a fix for the other open issue, which I am planning to push this week. This fix requires quite a lot of refactoring, therefore it is not yet ready to push with confidence ;) ... If you are okay with it, I would like to create one release solving both issues at once.

Hey @loedeman !
Releasing this week sounds good!
Let me know when it comes live.

Cheers.

Happy coding!
