How to debug ghost blog in development mode?

I am trying to debug posts data in post.hbs file Casper theme.

Code:

{{#get "posts" as |allposts|}}
       {{#each allposts}}
               {{ this }}
        {{/each}}
{{/get}}

Above code [Object Object] in webpage but if I use {{ log this }} I don’t see any logs in console. Any idea why so? Also is it possible to add custom helpers in ghost to output data?

Which console are you referring to? The log helper will output to your Ghost logs, so you should see it when running ghost log -f
