Query Build Join Fails

This is only returning one table, with no joins. I've tried doing the namespaced.* thing for each table, but that doesn't work

    $namespaced_table = 'Plc\\'.ucfirst('reports').'\\'.\Phalcon\Text::camelize('report_tools');
    $namespaced_table1 = 'Plc\\'.ucfirst('reports').'\\'.\Phalcon\Text::camelize('tools');
    $namespaced_table2 = 'Plc\\'.ucfirst('reports').'\\'.\Phalcon\Text::camelize('tool_content');
    $namespaced_table3 = 'Plc\\'.ucfirst('reports').'\\'.\Phalcon\Text::camelize('tool_scripts');

    $query_object = $this->modelsManager->createBuilder()
    ->leftJoin($namespaced_table1, $namespaced_table.'.tool_id=t.id', 't')
    ->leftJoin($namespaced_table2, 'tc.tool_id=t.id', 'tc')
    ->leftJoin($namespaced_table3, 'ts.tool_id=t.id', 'ts')
    ->where($namespaced_table.'.report_id = 209');

SQL output:

SELECT `report_tools` FROM `reports_alpha`.`report_tools` LEFT JOIN `reports_alpha`.`tools` AS `t` ON `report_tools`.`tool_id` = `t`.`id`  LEFT JOIN    `reports_alpha`.`tool_content` AS `tc` ON `tc`.`tool_id` = `t`.`id`  LEFT JOIN `reports_alpha`.`tool_scripts` AS `ts` ON `ts`.`tool_id` = `t`.`id`  WHERE `report_tools`.`report_id` = 209

report_tools replaced with * is valid SQL

When I alter to (columns, multi-table *)

    $query_object = $this->modelsManager->createBuilder()
    ->leftJoin($namespaced_table1, $namespaced_table.'.tool_id=t.id', 't')
    ->leftJoin($namespaced_table2, 'tc.tool_id=t.id', 'tc')
    ->leftJoin($namespaced_table3, 'ts.tool_id=t.id', 'ts')
    ->where($namespaced_table.'.report_id = 209');

I get

Fatal error: Uncaught exception 'Phalcon\Mvc\Model\Exception' with message 'Unknown model or alias 'Plc\Reports\Tools' (2), when preparing: SELECT...

I did a successful stand alone SELECT on 'Plc\Reports\Tools', so I know that the model etc is good.



I think this is fixed in 1.3.2, could you try please with that version?

We're having trouble with the install of that branch:

git clone --depth=1 git://github.com/phalcon/cphalcon.git
git checkout -b 1.3.2
cd build
sudo install
apache restart

phpinfo() still reports 1.3.1 after going through the compile process, and restart

Phalcon Framework   enabled

The install issue was taken care of by

git pull origin 1.3.2

But there is still a join issue: the current test errors with:

Plc\Reports\ToolContent , tc.tool_id=t.id , tc , Plc\Reports\Tools , Plc\Reports\ReportTools.tool_id=t.id , t , Plc\Reports\ToolScripts , ts.tool_id=t.id , ts , report_id = 209 ,

Finally got things resolved.

Quirk discovered - tables had to be aliased in order to be found. Via addFrom etc

I have the same problem on 1.3.0

How did you aliased table names?


I have the same problem on 1.3.4


could you share the solution for us?

i have this problem too in 1.3.4

$shows = $this->modelsManager->createBuilder()->from('Model\Stat\Content\Show')
            ->where('content_id = :contentId:', ['contentId' => $content->getId()])
            ->join('Model\Device\Device', 'Model\Device\Device.id = Model\Stat\Content\Show.device_id', 'device');
            ->orderBy('date_start DESC')

Phalcon\Mvc\Model\Exception: Unknown model or alias 'Model\Device\Device' (1), when preparing: SELECT [Model\Stat\Content\Show].* FROM [Model\Stat\Content\Show] JOIN [Model\Device\Device] AS [device] ON Model\Device\Device.id = Model\Stat\Content\Show.device_id WHERE content_id = :contentId: ORDER BY date_start DESC
