Access parent data from a nested template

[StrouMfios]

I am trying to access the parent data from a nested template but I am getting "Error: data.parent is undefined"

In my 'master' template I have the declaration

{{for Rooms tmpl="#RoomTmpl" layout=true /}}

and in the #RoomTmpl

<script id="RoomTmpl" type="text/x-jsrender"> {{:parent.parent.data.Room1Label}} (Here is the error) {{for #data}} {{:RoomName}} {{/for}} </script>

I tried also this {{:#parent.parent.Room1Label}} but with no luck

I had tried {{:#parent.data.Room1Label}} but no {{:#parent.parent.data.Room1Label}}
So, the correct one is {{:#parent.parent.data.Room1Label}}
Sorry, but I find it right after my post.

Thanks anyway

Yes, #foo is short for #view.foo, so #parent means #view.parent. OTOH if you just put parent, it is going to look for a data property called parent, i.e. #data.parent where #data is your current data item.

Well, I managed to get the parent data by using {{:#parent.parent.data.Room1Label}}
but now I am facing the same problem while I am in a layout loop

{{for #data}}
{{:#parent.parent.data.Room1Label}}
{{//for}}

It does not return the property value. If I do the same outside the loop, works fine.

Also, the weird thing is (please have a look at the following code)

In "Master template" I have nested template but it doesn't return any data
{{for Room1 tmpl="#RoomTmpl" layout=true /}}

//RoomTmpl
< s cript id="RoomTmpl" type="text/x-jsrender">
{{:#parent.parent.data.NumberOfRoomsSearched}}
< / script>

BUT!
If I use it like the following, It worked as I excpected.

In "Master template"
{{if NumberOfRoomsSearched>=1}}
{{for Room1 tmpl="#RoomTmpl" layout=true /}}
{{/if}}

Am I doing something wrong?

Thanks again Boris

You need to understand the way the view hierarchy works.
See #96, and also the reply I just posted on StackOverflow.http://stackoverflow.com/a/10452828/1054484

That added {{if}} tag is adding a nested view, but with the same data property as it's containing view.

Thanks a lot Boris. I liked the trick by using template variables.
