Rendering a partial within a loop

[lagartoflojo]

Hi,
I'm trying to render a partial multiple times (for the index action) and it's only returning the last item:

Partial _child.json.jsonify

json.name child.name

File index.json.jsonify

@children.each do |child|
  json.ingest!(render partial: child)
end

Actual result:

{"name":"Pedrito"}

Expected result:

[{"name":"Horacio"},{"name":"Pepito"},{"name":"Pedrito"}]

I also tried:

@children.each do |child|
  json << json.ingest!(render partial: child)
end

But the result was:

{"name":"Pedrito","#<Jsonify::JsonObject:0x00000002333ef0>":null,"[#<Jsonify::JsonPair:0x00000002320df0 @key=\"name\", @value=\"Pepito\">]":null,"[#<Jsonify::JsonPair:0x00000002306658 @key=\"name\", @value=\"Pedrito\">]":null}

I'll take a look today at your problem ... until I get that fixed, you could just skip the partial ...

@children.each do |child|
json.name child.name
end

Thank you!
Yes, that's how I generated the "expected result".

Hi
I am looking for the same thing. Any solutions for this?

I have this working like this:

@children.each do | child |
    json << JSON.parse(render 'child', child: child)
end

Not very efficient because Jsonify is converting the partial into a string and JSON.parse is converting it back into a hash, but it works.
