Problem passing a json object to controller

[Patito Feo]

Hi,

Ive been trying to pass an object with keys to the controller. But i havent been able to extract the request.vars.

Here is my view:

var Cars = {}

Cars.make = 'Ford';

Cars.model = 'Mustang';

Cars.year = 1969;

$.post( "{{=URL('default', 'transcriptor')}}", //request.post_vars.json1

   {     

         tarea: 'solicitudguardar', items: { json1: JSON.stringify( Cars ) }

   }, )

Here is my function:

elif request.vars.tarea == 'solicitudguardar':

   var = json.loads ( request.post_vars.items[json1] )

       

       

Here is one of the errors i got:

global name 'json1' is not defined

I dont understand why the array object is not being process as a json array in controller. 

Any help will be much appreciated.

Cheers,

[Javier Pepe]

You need use:

   var = json.loads ( request.post_vars.items["json1"] )

Javier, 

Tested and not working.

<type 'exceptions.TypeError'> 'builtin_function_or_method' object has no attribute '__getitem__'

request.post_vars	<Storage {'tarea': 'solicitudguardar', 'items[json1]': '[1,2,3]'}>

Any ideas?

Thanks for your reply,

Hi,

Try this, write down at the begin of the controller

print request.vars

you will see how the controller receives the information and then you will know if it's a js problem or a server side problem.

with your code what the controller receives is 

<Storage {'tarea': 'solicitudguardar', 'items[json1]': '{"make":"Ford","model":"Mustang","year":1969}'}>

you don't need to use  json.loads, you just need this

mydata = request.vars['items[json1]']

print mydata

{"make":"Ford","model":"Mustang","year":1969}

Paco here is the reponse:

1. {vars: {…}, respuesta: "noexiste"}
1. respuesta: "noexiste"
2. vars: {tarea: "solicitudguardar", items[json1]: "[1,2,3]"}
3. __proto__: Object

Thanks in advance,

Hiiii again :)

I think the problem is this

Instead of

request.vars.items[json1]

use this

request.vars['items[json1]']

because the var is 'items[json1]' requests.vars.items[json1] will look for the key 'json1' in the dict var items and there is no items var only a 'items[json1]' var that's why you need to use ['items[json1]'] and not items[json1]
