Need to display if a Asset field within a Matrix field has a file or not. While this works, the overhead is really high. Is there a way to write this with less overhead? Based on the EE template debug, here's the simplified snippet that causes the most lag:

{exp:channel:entries}
       {exp:playa:parents}
          {if '{matrixfield search:assetfield="not IS_EMPTY"}{row_id}{/matrixfield}'!=""}
             I'm not blank!
          {/if}
       {/exp:playa:parents}
{/exp:channel:entries}

Using the search+row_id is most efficient way I've tested to write it, but it's still some 2k queries/8sec vs the 100/.xsec the site normally has. With the Asset in Matrix, in Playa, in Entries I would expect some additional processing time. Open to any ideas to try!

  • Could you not just check to see if the matrix cell is empty by using the matrix column name rather than actually checking the Asset field within the Matrix field?

  • The column name calls the Assets plugin. {matrixfield}{asset_column_name}{/matrixfield} had even more overhead. Unless there's a way to ask for that column without using the cell name itself. Is that what you were suggesting or did I miss something?

  • Blair, I think I'm confused as well. Have you tried {matrixfield}{if asset_column_name != ""}{row_id}{/if}{/matrixfield}?

  • I didn't know that was a tag. Where's the docs for it and I'll give it a shot?

  • Ok, sorry, brain fail. The asset_column_name (what I called assetfield, which is really called audio_file) used in that way gives about another 300 queries. I did try that.

I have the same problem - did you ever discover a good way to get around the n+1 problem?
