Referencing ${current.id} in repeaters?

[John White]

As part of my attempt to work with Relationships, I'm trying to display a BlogPost page and show the Categories the post belongs to.

My schema definition has the relationship as manyBlogPosts have manyCategories.

I'm trying to construct a BlogPost page that takes the UUID of the BlogPost object and displays the page. Throughout the page, I'm referencing ${current.name}, ${current.title}, ${current.text}, etc. However, when I construct a repeater div to show all the Categories, I run into problems.

What works: 

REST Query: BlogPost/<actual UUID of a BlogPost Node>/manyCategories

What doesn't work:

REST Query: BlogPost/${current.id}/manyCategories

Functional Query: find(${current.manyCategories})

Functional Query: ${current.manyCategories}

Any pointers on the proper way to do this?

For whatever reason, this is working now:

REST Query: BlogPost/${current.id}/manyCategories

Hi John,

you are on the right track - I would handle this slightly differently, though.

The only thing that our UI maybe did not communicate clearly is that the "Function Query" is always treated like a scripting environment, which means that you don’t need surrounding "${ … }" for StructrScript.

For JavaScript you’d surround your code with "{ … }". Basically a single wrapping "${}" is automatically introduced.

So the easiest way would be to use a "Function Query" with "current.manyCategories".

The REST query you constructed also works.

Hope that helps!
