missing partials with rails - ruby-on-rails

Question

def some_action
#posts = Post.all
render partial: 'layouts/things'
end
In my layouts directory I have things as partial (_things.html.erb)
My other partials work fine. But it doesn't render partial throwing exception as
Missing partial layouts/things with {:locale=>[:en], :formats=>[:json], :handlers=>[:erb, :builder, :raw, :ruby, :jbuilder, :coffee]}. Searched in: * "/my/path/appname/app/views"
Edit-1
def some_action
#posts = Post.all
respond_to do |format|
format.json
end
end
Ok i changed my controller link this but then too same exception.
Edit-2
I have created in my views/controller_name/_some_action.json.erb
This is the controller
def some_action
#posts = Post.all
respond_to do |format|
format.json { render json: #posts }
end
end
My _some_action.json.erb file has
<%= render partial: 'shared/information', post: #posts.name %>
And created _information..js.erb in views shared directory
MY _information.js.erb has sample text as
test
I am getting json response from controller i checked with inspect element. But it is not render actual text i need (i.e., test)

Answer 1

well, IMHO you need to name your partial like
_things.js.erb
or no?

Answer 2

As Jacub Kuchar mentions, if you're trying to provide a JSON response, your partial should be named accordingly (i.e. _things.js.erb). You should also put it in the 'shared' directory rather than 'layouts' as it's a partial, not a layout.
However, I'd also keep the logic of which view to render of the controller and let the view itself handle it.
So your controller can simply say:
respond_to :json # (and whatever other response types you want to support: xml, etc)
def some_action
respond_with #posts = Post.all
end
And then having a matching view, under views/{controller name}/some_action.js.erb, which says:
<%= render partial: 'shared/things', posts: #posts %>
That way your controller isn't polluted with view logic.
