collection.create doesn't save a model's children about ampersand-rest-collection HOT 6 OPEN

Hi folks, any idea how to perform this?

from ampersand-rest-collection.

@e2jk, can you post your model definition and example form data?

from ampersand-rest-collection.

The model definition: http://pastebin.com/iMkFb3TG

When posting information on the page to create a new record, the following data is posted from the form:

{"abbreviation":"Test Object","objectType":"Interface","description":null,"notes":null,"fromDate":null,"toDate":null,"numberOfRecords":null,"relatedGroup":{"abbreviation":"","name":""},"fromSystem":{"systemName":"","vendorName":"","contactName":"","contactPhone":"","contactEmail":""},"toSystem":{"systemName":"","vendorName":"","contactName":"","contactPhone":"","contactEmail":""},"responsiblePerson":{"firstName":"","lastName":""}}

As you can see, all the data from the children is empty.
Since I'm saving again the model after it has just been created (again, with the same data from the form), a PUT command is issued just after that, which has all the children item populated:

{"id":13,"abbreviation":"Test Object","objectType":"Conversion","description":null,"notes":null,"fromDate":null,"toDate":null,"numberOfRecords":null,"relatedGroup":{"id":2,"abbreviation":"ENC","name":"Afspraak en Opname","objects":[4,5,6,7,8]},"fromSystem":{"id":9,"systemName":"SchedulePlus","vendorName":"","contactName":"","contactPhone":"","contactEmail":"","fromObjects":[]},"toSystem":{"id":11,"systemName":"New EPD","vendorName":"EPD vendor","contactName":"Toto van der Been","contactPhone":"9898989898","contactEmail":"[email protected]","fromObjects":[10],"toObjects":[7]},"responsiblePerson":{"id":5,"firstName":"Rob","lastName":"van Egmond"}}

I've added a debug console log just after submitCallback, and the JS object that is the data variable does have properties named as the children, which are themselves objects that contain the data. Example from this Firefox web tools screenshot:

from ampersand-rest-collection.

This is the text version of the screenshot (with another object I've just created). It's the output of console.log(JSON.stringify(data)); just after submitCallback is called.
You'll notice that the children data are sent themselves as objects (e.g. embedded objects). And as mentioned, when calling model.save with the same data in the success callback of app.objects.create, the model is properly saved (i.e. the issue is not in data, but likely in the way children are saved when calling collection.create whereas model.save works flawlessly):

19:30:17,492 "{"abbreviation":"XXX","objectType":"Conversion","description":"This is a test","notes":"These are notes","fromDate":null,"toDate":null,"numberOfRecords":null,"relatedGroup":{"id":2,"abbreviation":"ENC","name":"Afspraak en Opname","objects":[4,5,6,7,8]},"fromSystem":{"id":2,"systemName":"Radiologix","vendorName":"Radiologix","contactName":"David Seller","contactPhone":"123456789","contactEmail":"[email protected]"},"toSystem":{"id":3,"systemName":"PharmaPill","vendorName":"","contactName":"","contactPhone":"","contactEmail":""},"responsiblePerson":{"id":2,"firstName":"Marcel","lastName":"Eiffel","objects":[3,9,10]}}"1 project-de-brug.nonCached.js:911:1

Hi there, any thoughts about this issue?

from ampersand-rest-collection.

I couldn't understand from your pastepin what you are trying to do. Try to create a minimal example that doesn't work. I sense that you may be mixing between children and collections.
