Is it possible in Sailsjs to build more complex models

Question

I would like to have arrays or collections in my model, is this yet possible with waterline (mongoDB)? are there any alternatives around?

example:

{
   n

I don't know if this is still an issue, but the trick is to neither POST as "form-data" nor "x-www-url-encoded". You have to POST the "raw" content:

Assume the situation:
http://www.example.com/mymodel

---

form-data

Your Header may look like this:

POST /mymodel/create HTTP/1.1
Host: www.example.com
Cache-Control: no-cache

----WebKitFormBoundaryE19zNvXGzXaLvS5C
Content-Disposition: form-data; name="basicModules"

[1,2,3,4]
----WebKitFormBoundaryE19zNvXGzXaLvS5C

the result is that a string "[1,2,3,4]" gets (type-)validated, which fails

---

x-www-url-encoded

In this case the Header is something like this:

POST /mymodel/create HTTP/1.1
Host: www.example.com
Cache-Control: no-cache
Content-Type: application/x-www-form-urlencoded

basicModules=%5B1%2C2%2C3%2C4%5D

which has exactly the same result as form-data. validation fails because of basicModules being the string "[1,2,3,4]"

---

raw

to make it work your Header has to look like this:

POST /mymodel/create HTTP/1.1
Host: www.example.com
Cache-Control: no-cache

{"basicModules":[1,2,3,4]}

which results in just exactly what you want, and type validation works.

---

so in the end, you can fill the most complex models that way in JSON. e.g.

POST /mymodel/create HTTP/1.1
Host: www.example.com
Cache-Control: no-cache

{"user": {
         "name": {
           "first":"John",
           "last":"Doe"
         },
         "age":25,
         "pets":[{
           "name":"Garfield",
           "type":"cat"
         },
         {
           "name":"Rudolph",
           "type":"reindeer"
         }]
       }
