"for" syntax is not work with dictionary

[linuxpham]

Hi Admin,

{% for key, value in dict_item.items() %}

Key: {{key}}

Value: {{value}}

{% endfor %}

It is not working.

Thanks!

Could you provide more detailed sample of the problem which I can add to C++/Python tests as-is?

This is an example:

nlohmann::json dict_item = {"AD":"376","AE":"971","AF":"93"};
{% for key, value in dict_item.items() %}
Key: {{key}}
Value: {{value}}
{% endfor %}

I see a least one issue here. There is no user-callable 'items' in nlohmann::json reflection. I suppose, you need to replace dict_item.items() with dict_item in your sample.

What the result of this sample template processing:

{%set inner_items={"AD":"376","AE":"971","AF":"93"} %}

{% for key, value in inner_items %}
Key: {{key}}
Value: {{value}}
{% endfor %}

it does not work. The result is empty!
I think the "for" syntax only works with "array" data.

Ok. Thanks! I'll check it out.
