Relationship parents does not work
How Do I?
Please, help me understand.
Here is my structure:
› CHANNEL_ONE
-- {title}
-- {url-title}
-- {channel-one-grid}
---- {field1}
---- {channel-two-relationship} *(multiple)*
---- {field2}
---- {field3}
› CHANNEL_TWO
-- {title}
-- {url-title}
-- {ch2field1}
-- {ch2field2}When i’m on a CHANNEL_TWO entry page, how i can show all entries from CHANNEL_ONE that listed this CHANNEL_TWO entry as related?
Here is my current code that does not work:
<body>
{exp:channel:entries channel='CHANNEL_TWO' limit='1' require_entry='yes' disable='categories|member_data|pagination|category_fields'}
{title}
...
etc
{/exp:channel:entries}
{exp:channel:entries channel='CHANNEL_TWO' require_entry='yes' disable='categories|member_data|pagination|category_fields'}
{parents field='channel-one-grid:channel-two-relationship'}{parents:title}{/parents}
{/exp:channel:entries}
</body>What i get:

Also tried this code (and its variations):
{exp:channel:entries channel='CHANNEL_TWO' disable='categories|member_data|pagination|category_fields'}
{channel-one-grid}
{channel-one-grid:channel-two-relationship:parents field='channel-one-grid:channel-two-relationship'}{parents:title}{/channel-one-grid:channel-two-relationship:parents}
{/channel-one-grid}
{/exp:channel:entries}Getting this error:

{exp:channel:entries channel='CHANNEL_ONE|CHANNEL_TWO' disable='categories|member_data|pagination|category_fields'}
{channel-one-grid}
{channel-one-grid:channel-two-relationship}
{channel-one-grid:channel-two-relationship:parents field='channel-one-grid:channel-two-relationship'}
{channel-one-grid:channel-two-relationship:parents:title}
{/channel-one-grid:channel-two-relationship:parents}
{/channel-one-grid:channel-two-relationship}
{/channel-one-grid}
{/exp:channel:entries}
I’m not surprised the field parameter doesn’t take a grid field. Does it work if you leave that out?
{exp:channel:entries channel='CHANNEL_TWO' require_entry='yes' disable='categories|member_data|pagination|category_fields'}
{parents}{parents:title}{/parents}
{/exp:channel:entries}There’s a reported bug using Parent fields with file grids, which share a lot of code. (https://github.com/ExpressionEngine/ExpressionEngine/issues/432). If it fails, I think the best option is to add a comment there and stay subscribed.
Thank you, Robin Sowell!
Trying to come up with workaround, started new forum topic: https://expressionengine.com/forums/topic/252782/how-to-use-expquery-results-in-expchannel-parameter
Is there a chance EE to fix this bug? Or i need to think of alternatives?
Quick update on this one, we just pushed a fix for this to the repo and it will be in the next release.
