rendering multiple files - rails

Question

Suppose I make an ajax a call, from which I want to get some static template (app/views/static/some_template.html.erb), on which I want to act with some javascript stored here app/views/layouts/sign_in.js.erb. Is it possible to render multiple file ? (because I want to keep separate my js files and my html files)

def ajax_call
   respond_to do |format|
    ...
    format.js {render 'layouts/sign_in.js.erb'}
   end
end

Edit : here's my controller

    respond_to do |format|
       format.js {render 'devise/sessions/new.html.erb'}
    end

In devise/sessions/new.html.erb, I put

<div> test</div>
<%= render "layouts/sign_in.js.erb" %>

and in layouts/sign_in.js.erb, I put console.log('test');

You can put renders inside the partial and segment your files one more level:

def ajax_call
   respond_to do |format|
    ...
    format.js {render 'layouts/grouped_sign_in.js.erb'}
   end
end

# in _grouped_sign_in.js.erb
<%= render 'layouts/sign_in.js.erb' %>
<%= render 'layouts/create_account.js.erb' %>

In fact, I put a console.log(test) inside my sign_in.js.erb file, but it seems not to be evaluated as javascript but instead as plain text. How can it be ?

It still doesn't work I added <%= javascript_tag do %>console.log("test");<% end %> and I get <script> //<![CDATA[ console.log("test"); //]]> </script>

What is the source code? Can you pastebin it please? I think that there is nested <script> tags, 1 global with 2 inside.

I reduced the html part of the template to <div>test</div> and it still get the same problem...

Perhaps it is related to the fact that I render in my controller some static page format.js {render 'static/new.html.erb'} (I put at the bottom of this page <%= render 'layouts/sign_in.js.erb' %> )

What you can do is the following

In your controller

@template = ActionView::Base.new('app/views/static', {}, ActionController::Base.new).render(file: 'new').to_s

respond_to do |format|
    format.js {render 'layouts/sign_in.js.erb'}
end

and then get your @template variable back in your sign_in.js.erb, <%= escape_javascript(@template) %>
