I've a problem on joining 2 tables, it doesn't recognise the "atleta" primary key to join to "socio.user", or still, i don't know how to set it.

I used quite all the "relation" combination to make it, but it still leaves the atleta column empty.

Here's the error:

1054 Unknown column 'atleta.' in 'on clause' SQL=SELECT COUNT(*) AS `socio.count` FROM `myaiq_librosoci` AS `socio` LEFT JOIN `myaiq_atleti` AS `atleta` ON `socio`.`user` = `atleta`.``;



it should be " ON `socio`.`user` = `atleta`.`id`; "

Hi,

What is the primary model here ? both tables have primary keys ? please post a screenshot of the secondary model settings section.

Best regards,

I tried to name both the primary key as user_id [yeah they're both primary and unique keys]

still: 1054 Unknown column 'atleta.' in 'on clause' SQL=SELECT COUNT(*) AS `socio.count` FROM `#__librosoci` AS `socio` LEFT JOIN `#__atleti` AS `atleta` ON `socio`.`user_id` = `atleta`.``;

I tried to use the custom Project "articles relaction":

1054 Unknown column 'Author.' in 'on clause' SQL=SELECT COUNT(`Article`.`id`) AS `Article.count` FROM `#__content` AS `Article` LEFT JOIN `#__users` AS `Author` ON `Article`.`created_by` = `Author`.``;

Same problem

It looks like there is a problem getting the primary key of the table, what is your mysql version ? could you please try to click the "delete cache" button in the admin area ?

MySQL 5.6.33-cll-lve - MySQL Community Server (GPL)

Tried. Nothing at all.
I also used a brand new database without views (trying to understand if primary keys depends on it), nothing.

Hi elgenoveis,

What is the result when you run the following query in your phpmyadmin:
DESCRIBE #__content;

?

DESCRIBE #__content;

Hi elgenoveis,

Ok, I'm not sure why this problem occurs but you can use the "relation conditions" instead of the foreign key:
Article.created_by:Author.id
