I've got an issue reading a nested array from JSON(BSON from MongoHQ) using Node and Angular.

JSON snippet: http://pastie.org/9305682. Specifically look for the edges array.

Mongoose model: http://pastie.org/9305685

Basically I call the character from the DB and then attempt to log it to the console with console.log(char); before sending it back to the angular call with res.json(char); 'char' is the returned character from the databased saved as my mongoose model.

Attempting to log the character to the console. I get everything looking normal except for the portions with the nested "effects" arrays. Anywhere they show up I receive the following:

edges:                                                                                                                                                                                                                                        
 [ { name: 'Super Hacker', notes: '', effects: [Object] },                                                                                                                                                                                    
   { name: 'Witty', notes: '', effects: [Object] },                                                                                                                                                                                           
   { name: 'Attractive', notes: '', effects: [Object] },                                                                                                                                                                                      
   { name: 'Encyclopedic Memory',                                                                                                                                                                                                             
     notes: 'Prereq: d8 Smarts',                                                                                                                                                                                                              
     effects: [Object] },                                                                                                                                                                                                                     
   { name: 'Daywalker', notes: '', effects: [Object] },                                                                                                                                                                                       
   { name: 'Tough', notes: '', effects: [Object] } ],

From here if I try to call it with:

From NodeJS - console.log(char[0].edges[0].effects[0].type); - Returns undefined.

From Angular View - {{cur_char.edges[0].effects[0].type}} - Displays nothing.

Thanks in advance for the help. Let me know if I can provide more in.

Have you tried just console.log(char[0].edges[0].effects[0]), to see if the object is being returned as JSON? –  JoshSGman Jun 19 at 16:50
    
Calling this I get [object Object]. –  Tyrrexx Jun 19 at 18:13

I think what you're asking is how to see more depth to the object in the console output. You can use util.inspect to print out more information:

console.log(util.inspect(char, { depth: 5 }));

By default util.inspect only goes to a depth of 2 which explains why you can only see the contents of the array (1) and the primitive properties of each element in the array (2).

See: http://nodejs.org/api/util.html#util_util_inspect_object_options

Okay, I've tried this out. I still get the same result of [object] though. –  Tyrrexx Jun 19 at 19:20
    
It appears to work for me. Here is a script I created to test it out. On screen I see effects displayed in console for all the edges. gist.github.com/anonymous/f8f29903010a6f425e03 I named the file char.js and ran it with: node char.js –  Hayes Jun 19 at 19:32
    
Hmm yeah doing it that way works for me too. I believe the issue was that the effects array needed to be treated as its own schema. Regardless I've decided just to keep effects as a single array of strings instead of anbarray of objects. Thanks for the help! –  Tyrrexx Jun 20 at 17:21
