should includes inherit parent properties?

[RandomEtc]

If I do:

res.locals.user = { name: 'Tom' }
res.render('page')

And in page.ect I do:

<% include 'user' %>

I'd like user.ect to have access to @user. Currently I must pass user explicitly:

<% include 'user', { user: @user } %>

This can get tedious for complex page. Is there a better way?

By default all variables available in all templates hierarchy. But it can be overwritten. You don't need to pass user variable into include in your case.

Right. Sorry.

The use-case I'm thinking of is when I want to use an include to render an item in a collection, so I want to pass some one-off parameters to the included template as well as the parameters from the calling page.

So if I do:

res.locals.users = [ { name: 'RandomEtc' }, { name: 'baryshev' } ]
res.locals.otherInfo = 'foo'
res.render('page')

And in page.ect I do:

<% for user, i in @users: %>
  <% include 'user', { user: user, index: i } %>
<% end %>

I'd like user.ect to have access to @otherInfo. Currently I must pass it explicitly:

<% for user, i in @users: %>
  <% include 'user', { user: user, index: i, otherInfo: @otherInfo } %>
<% end %>

I should have used this example previously, apologies.

...

Thinking about it, I guess I could just expose an extend (or inherit or merge) helper method and do this:

<% for user, i in @users: %>
  <% include 'user', @extend(this, { user: user, index: i }) %>
<% end %>

But I'm wondering if this would be useful default behavior?

Sorry, there is no native way to merge parameters right now. Merge may cause performanse issues in this context.

OK I'll write a helper.
