阅读更多关于 How do I build a UNION query with ORDER BY and GROUP BY in Kohana's query builder?

问题 I'm trying to build a UNION query using Kohana's query builder. Everything works fine until I add a GROUP BY or ORDER BY clause. Here is the code I'm using (simplified): $query1 = DB::select('p.name') ->from(array('person', 'p')) ->where('p.organization', 'LIKE', 'foo%') ->limit(10); $names = DB::select('sh.name') ->union($query1, FALSE) ->from(array('stakeholder', 'sh')) ->where('sh.organization', 'LIKE', 'foo%') ->group_by('name') ->order_by('name') ->limit(10) ->execute() ->as_array();

kohana 3.2 ORM find_all() with relationships

阅读更多关于 kohana 3.2 ORM find_all() with relationships

问题 I have 3 tables: artists{id,name} media{id,name,filename} media_artists{artist_id,media_id} I created the models with n-n relationships as described in the Kohana guide. When I do in a controller: $artist_view = new View('artists/profile'); $artist_id = $this->request->param('id'); $artist_view->artists = $artist_model->where('id', '=', $artist_id)->find(); $artist_view->media = $artist_model->media->find_all(); it works fine, and I can call the media entries related to this specific artist

Kohana 3.3 Not working from Subdirectory

阅读更多关于 Kohana 3.3 Not working from Subdirectory

问题 Answer: Kohana 3.3, they didn't take into account case-sensitivity on folders/files (they capitalized some directories/files) so this is going to drive some folks nuts when they start switching to the new Kohana (just like I did). I switched back to Kohana 3.2 until this has been fixed. Thank you very much for taking time in reading my huge post I had about this silly problem, and I hope this answer saves a poor souls life in the future =) 回答1: It is not correct that "they didn't take into

问题 Based on this documentation, I've implemented a catch all route which routes to an error page. Here is the last route in my bootstrap.php Route::set('default', '<path>', array('path' => '.+')) ->defaults(array( 'controller' => 'errors', 'action' => '404', )); However I keep getting this exception thrown when I try and go to a non existent page Kohana_Exception [ 0 ]: Required route parameter not passed: path If I make the <path> segment optional (i.e. wrap it in parenthesis) then it just

How to integrate Wordpress into Kohana 3

阅读更多关于 How to integrate Wordpress into Kohana 3

问题 I now need to make a Kohana 3 site have a Wordpress blog. I've seen Kerkness' Kohana For Wordpress, but it seems to be the opposite of what I want. Here are the options I have thought of Style a template to look exactly like the Kohana site (time consuming, non DRY and may not work) Include the blog within an iframe (ugly as all hell) cURL the Wordpress pages in. This of course means I will need to create layers between comment posting, etc, which sounds like too much work. Is there any way I

What should I do with Kohana 3 to make route actions' hyphens change to underscores?

阅读更多关于 What should I do with Kohana 3 to make route actions' hyphens change to underscores?

Consider this route in bootstrap.php ... Route::set('crud', 'staff/<controller>(/<action>(/<id>))', array( 'controller' => '(activities|users|default-emails)', 'action' => '(new|view|modify|delete)', 'id' => '\d+' ))->defaults(array( 'directory' => 'staff', 'action' => 'view' )); The default-emails is trying to run the action_default-emails() method which obviously doesn't and can't exist. What part of Kohana should I extend to map that hyphen into a underscore internally? Should I be concerned that if I do do this, then it will be accessible via both _ and - delimited routes? Thanks. The

When using Kohana DB, how does one avoid duplicate code when needing a count for pagination?

阅读更多关于 When using Kohana DB, how does one avoid duplicate code when needing a count for pagination?

问题 Using the Kohana query builder, is it possible to build my query piece by piece. Then execute a count on said query. Then execute the query itself. All without having to write duplicate conditionals... one for the count and one for the results... Adding DB::select(array('COUNT("pid")', 'mycount')) To the main query results in only getting back one record. Is it maybe possible to execute the count, and somehow remove array('COUNT("pid")', 'mycount') from the select... Right now the only way I

In Kohana 3, how do you figure out errors made during a query?

阅读更多关于 In Kohana 3, how do you figure out errors made during a query?

问题 I'm using Kohana 3. I'm writing an update query, and it is working for everything except this one section. If I do a var_dump() on the results of $db->execute() I get either a 1 or 0 to say it failed or not. It is failing in this example (returning 0). How can I figure out what error is happening? It justs seems to be silenty failing at the time being. I tried doing echo mysql_error() but it didn't work, as I expected, as Kohana 3's db library uses PDO I'm pretty sure. How can I figure out
