return json to client with {ok, xxx} not {json, xxx}

[Caiyun Deng]

Hi!

In the controller, "TestInfos = [[{name, "test1"}], [{name, "test2"}]], {ok, [{test_infos, TestInfos}]"

In the javacript, the value is not json array.

$(document).ready(function(){

    console.log("*******", {{ test_infos }});

It will  "Uncaught SyntaxError: Unexpected token , " --> console.log("*******", {name,"test1"}{name,"test2"});

I know i can return {json, [{test_infos, TestInfos]} to achieve this.

But i want to return by {ok, [{test_infos, TestInfos}]} and the client get {{ test_info }} is a json array, so i can use javascript to handle it in some particular situations, not to request the server one more time to get the value.

hi,

you can use custom filter: 

src/view/lib/filter_modules/<app_name>_custom_filters.erl

to_json(Record) when is_tuple(Record) ->
    Type = element(1, Record),
    boss_json:encode(Record:attributes(), [Type]);
to_json(Proplists) ->
    boss_json:encode(Proplists, []).

in your controller:

action('GET', []) ->

Condition = [],

Record = boss_db:find_first(my_model_name, Conditions),

{ok, [{record, Record}]).

in your template:

<script>

{% autoescape off %}

var data1 ={{ Record | to_json }};

var data2 ={{ Record.attributes | to_json }};
{% endautoescape %}

</script>

should work , you can easily modify it to your need.
