  • SEO Friendly URLs where the phrase used may change in Rails

    - by Newy
    Say I have http://www.mysite.com/I-Like-Cheeseburgers and I want that to point to Item with id 3. Sometime later, I change the name of the item, and now its http://www.mysite.com/I-Like-Hamburgers (and perhaps many more times). I want all these URLs to remain pointing to Item 3. Is it efficient to simply keep a table of [strings,item_ids] and do a lookup on this? Is there a better way?

  • Reset SQL variable inside SELECT statement

    - by Jason McCreary
    I am trying to number some rows on a bridge table with a single UPDATE/SELECT statement using a counter variable @row. For example: UPDATE teamrank JOIN (SELECT @row := @row + 1 AS position, name FROM members) USING(teamID, memberID) SET rank = position Is something like this possible or do I need to create a cursor? If it helps, I am using MySQL 5.

  • Library to edit odt documents in php

    - by neo
    I try to edit ODT-documents programmaticly in PHP. In fact I just want to do some text replacement and adding new rows in a table. I know that a normal ODF document is an archive containing XML-files. But before I reinvent the wheel: is there any library which does most of the tasks? Or should I just parse the XML-file in a DOM-parser and modify it?

  • Drupal - Hide a single page from search index

    - by ilowe
    Hi, I've taken over an existing Drupal installation and have been asked to remove a single page from the site search results. I know about the lullabot tutorial through this question: http://stackoverflow.com/questions/1748837/hide-drupal-nodes-from-search, but that talks about excluding a class of content when I really just want to exclude a single page. I've tried manually deleting the node from the search_index table, but that didn't seem to work either. Any recommendations for excluding a single regular content page from the search index?

  • How to notify a Windows .net service from PHP on Linux?

    - by Louis Haußknecht
    I'm writing a service in C# on Windows which should be triggert by an PHP driven web frontend, which runs on Linux. Both processes share the same SQL Server 2005 database. There is no messaging middleware available atm. The PHP process inserts an row in a SQL Server table. The Windows process should read this entry and process it. I have no experience in PHP, so what would you suggest to notify the Windows process?

  • Cakephp beforeFind() - How do I add a JOIN condition AFTER the belongsTo association is added?

    - by michael
    I'm in Model-beforeFind($queryData), trying to add a JOIN condition to the queryData on a model which has belongsTo associations. Unfortunately, the new JOIN references a table in the belongsTo association, so it must appear AFTER the belongsTo in the query. Here is my Tagged-belongsTo association: app\plugins\tags\models\tagged.php (line 192) Array ( [Tag] => Array ( [className] => Tag [foreignKey] => tag_id [conditions] => [fields] => [order] => [counterCache] => ) [Group] => Array ( [className] => Group [foreignKey] => foreign_key [conditions] => Array ( [Tagged.model] => Group ) [fields] => [order] => [counterCache] => ) ) Here is the JOIN added in Tagged-beforeFind(), notice that the belongsTo joins have not yet been added: app\plugins\tags\models\tagged.php (line 194) Array ( [conditions] => Array ( [Tag.keyname] => europe ) [fields] => Array ( [0] => DISTINCT Group.* [1] => GroupPermission.* ) [joins] => Array ( [0] => Array ( [table] => permissions [alias] => GroupPermission [foreignKey] => [type] => INNER [conditions] => Array ( [GroupPermission.model] => Group [0] => GroupPermission.foreignId = Group.id [or] => Array ( ... ) ) ) ) [limit] => [offset] => [order] => Array ( [0] => ) [page] => 1 [group] => [callbacks] => 1 [by] => europe [model] => Group ) When I check the output, it fails with "1054: Unknown column 'Group.id' in 'on clause'" because the Permissions join appeared BEFORE the Groups join. SELECT DISTINCT `Group`.*, `GroupPermission`.* FROM `tagged` AS `Tagged` INNER JOIN permissions AS `GroupPermission` ON (`GroupPermission`.`model` = 'Group' AND `GroupPermission`.`foreignId` = `Group`.`id` AND (...)) LEFT JOIN `tags` AS `Tag` ON (`Tagged`.`tag_id` = `Tag`.`id`) LEFT JOIN `groups` AS `Group` ON (`Tagged`.`foreign_key` = `Group`.`id` AND `Tagged`.`model` = 'Group') WHERE `Tag`.`keyname` = 'europe' But this SQL (with Permissions joined moved to the end) works fine: SELECT DISTINCT `Group`.*, `GroupPermission`.* FROM `tagged` AS `Tagged` LEFT JOIN `tags` AS `Tag` ON (`Tagged`.`tag_id` = `Tag`.`id`) LEFT JOIN `groups` AS `Group` ON (`Tagged`.`foreign_key` = `Group`.`id` AND `Tagged`.`model` = 'Group') INNER JOIN permissions AS `GroupPermission` ON (`GroupPermission`.`model` = 'Group' AND `GroupPermission`.`foreignId` = `Group`.`id` AND (...)) WHERE `Tag`.`keyname` = 'europe' How do I add my join in beforeFind() after the belongsTo join?

  • UIWebView doesn't scroll to the bottom of the webpage loaded/created

    - by tom
    I have a UIWebView inside a normal UIViewController. The content of the UIWebView is programming/dynamically created in my program, and it could be very long (multiple table rows). Somehow, after loading, the page won't scroll more then one and half screen of content when swipe on the screen. Because of that I can only see the beginning few rows of data, but not the many others after them. Why is that?
