Use anonymous subobjects.

Greetings everyone,

I set multiple records of the same type on a single page, and try to #show them as format=table. The table is created just fine, but the #show does not create separate table rows. For each of the records, it appends as a newline in the first table row.

I did the following:

{{#set:NeedsResource=Travertine Slab;5}}
{{#set:NeedsResource=Marble Slab;1}}
{{#show: {{FULLPAGENAME}}
|?NeedsResource.Resource = Name
|?NeedsResource.NeedMin = Name
|format = table}}

I want the query to put each of the sets into a separate table row but can't seem to find a way to do so.

Any hints are very welcome!

Thanks

I keep getting Caught exception of type Flow\Exception\NoParserException when attempting to reply. Here's another try.

To store objects with their own property/value pairs, you should be using #subobject, not #set. See https://www.semantic-mediawiki.org/wiki/Help:Adding_subobjects. Or alternatively, place each set on its own page, if that works for you.

I've tried the subobject approach, but it enlists everything in one single table row aswell. Own page is a no-go. I want to set multiple properties of the same name for the same page, which works, just not the query results.

When I add subobjects and query them, e.g.

{{#ask: [[-Has subobject::{{FULLPAGENAME}}]] |?NeedsResource }}

I do get two distinct rows.

Just for clarity, I'm asuming there's a semicolon because you've defined the property as being one of data type "Record", right?

Yes that is correct, I wanted it to be a record with a few subproperties.

If I do this one:

{{#subobject: test
|level=1
|test=b
}}
{{#subobject: test
|level=2
|test=a
}}

{{#ask: [[-Has subobject::{{FULLPAGENAME}}]] |?test}}

there is only a single row:

I see, the problem is that you've given them identical names (test), which translates to a single subobject rather than two. You can either give them distinct names (e.g. test1 and test2) or leave that part blank, in which case SMW defaults to anonymous, hash-based identifiers.

Oh nice, the anonymous did the trick! Thanks!
