The first Drupal Cape Town meetup of 2017 took place at the Bandwidth Barn on the 22nd of February 2017.
What's been on my mind
One of the sites I maintain recently had a server upgrade to Ubuntu 14.04.4, which included a new version of varnish (version 3.05) which required an update to the Varnish configuration. After setting up a new default.vcl file I was monitoring the headers sent and received to make sure that what was supposed to be cached was in fact being cached by Varnish. While testing I discovered that I was not getting any Cache-Control headers from static files like images.
I'm a huge fan of Elon Musk, the world-changing, South African born pioneer of the consumer electric car and space technology company SpaceX, and was pleased to learn that both the Tesla website, and the SpaceX website are built on Drupal. Both are currently Drupal 7 sites with home pages that use beautiful images and videos (in the case of the Tesla site) to provide high visual impact and engagement.
I recently migrated a Drupal 6 site to Drupal 7 using the migrate and migrate_d2d modules. While testing the new site on my client’s server, every now and again ajax requests were failing, and page resources like images were not loading. The apache error log showed a number of “client denied by server configuration” errors.
I ran into issues when trying to use drupal's hook_form_alter to change some attributes of cck fields in a node form. It appears that depending on the weight of the module the form_alter is in, it might get called before the actual form element has been processed.
To make sure, you can set a function to be called after the form has been properly created, but before rendering.
In your form alter, add the after build key to the form field's array:
$form['field_course_status']['#after_build'] = 'course_disable_status_field';
Was adapting some views handlers that were used in Open Atrium, and came across a number of places where I saw some strange constants with three stars either side of them, like: ***ATRIUM_ACTIVITY_TIMESTAMP***
I recently created a provider plugin for Drupal's CCK emfield module which allows you allows you to embed a Zoopy video by pasting the url into a cck field:
This is a lot easier than having to copy the embed code provided by Zoopy and paste this into a textarea.
The provider plugin then extracts the video code and displays the video on your Drupal site:
These are some of the thoughts I shared at the Drupal Johannesburg meetup held on 11 March 2009.
My thoughts on the meetup
For me, it was great to see everyone again, although I was disappointed that there weren't more than 3 new faces among the 15 or so that turned up. We do need to do something to attract more new members. I particularly enjoyed hearing about what new modules people have discovered, and enjoyed the less formal discussions afterwards.
