Entity reference in node_save()

[j-hiertz]

Hi,

I have seeing this post about using entity reference in node_save() #418

I have a different problem,

"field_contrat": {
    "und":{
        "0":{                   
        "nid": form_state.values['n_contrat']           // form_state.values['nid_contrat'] doesn't work
        }
    }
},

This code search on title and not the nid of field_contrat but my title is not unique.

Error : POST http://example.com/?q=drupalgap/node.json 406 (Not Acceptable: Contract: no valid content was found for this title.)

Someone can help me ?

Thanks

@tsuuki Use target_id instead of nid.

I have tried this :

"field_contrat": {
    "und":{
        "0":{                   
        "target_id": form_state.values['nid_contrat']
        }
    }
},

and the result :

POST : http://example.com/?q=drupalgap/node.json - 406 - Not Acceptable
{" form_errors ": {" field_contrat ] [ und ] [ 0] [ nid ": " The Contract field is required . "}}

@tsuuki As you can see, it is still sending the nid for some reason instead of the target_id. Try this:

field_contrat: {
  und: [
    { target_id: form_state.values['nid_contrat'] }
  ]
}

[j-hiertz]

field_contrat: {
    und:[
        { target_id: form_state.values['nid_contrat'] }
    ]
},  

I've got this :

{"type":"contract","title":"test","body":"test","field_contrat":{"und [{"target_id":"90"}]},"language":"und"}
{" form_errors ": {" field_contrat ] [ und ] [ 0] [ nid ": " The Contract field is required . "}}

@tsuuki I believe this problem lies with whatever widget you have specified on the "Manage fields" tab in Drupal for your content type. Which widget are you using?
