Organic Groups (OG) in Drupal 7 has a role based permission system that works on a group by group basis. This permissions system works separately to the main Drupal permission system, which can cause a couple of issues. For example, if you want to give a group role access to give other users roles then you'll need to give them the 'Administer groups' permission. The downside of this is that it overrides Drupal's core permissions to do with node deletion and allows the role to delete the group.
I have been developing a site with the Drupal 7 Organic Groups (OG) module today and I found the need to grab a bunch of users from a group depending on their group role. The first parameter here is the group GID (not the node ID) and the second is an array of role ID's to use.
If you have changed or updated a git repository and want to throw away your changes then a good way of forcing the lastest changes to run a combination of two commands. The first command is git fetch --all, which tells git to download the latest updates from the remote without trying to merge or rebase anything. This is followed by git reset --hard origin/master where git resets the master branch (assuming you were on the master branch) to become the version of the master branch you just fetched. Here is the two commands in full:
After a recent update on Ubuntu I found that I was unable to use ssh due to a strange permissions error to do with the ssh config file. This was quite a problem as I wasn't able to push changes to my git server. The error was as follows:
I have started to use virtual machines to develop sites rather than installing a local web server. This allows me to replicate the exact setup of the server I will be deploying to with ease. For each virtual machine I set up a shared folder which allows me to store the files locally whilst being able to run the code on the virtual machine. One thing I missed was the ability to use xdebug to debug the sites through Netbeans, so I set about trying to set up the virtual hosts to allow me to use xdebug remotely.
Searching all files in a directory and sub-directories for a particular term is really useful and comes in handy in all sorts of situations. It is available on all Linux systems and the basic syntax is as follows.
grep -r -i pattern directory
The -r flag is used to recursively search underneath the given directory and the -i flag is used to ignore case. The pattern is a normal regular expression, which can be changed to an extended set by using the -E flag.
I have talked before about running Selenium tests in PHPUnit but I have only recently come to properly automate things. Getting a Selenium server to start and stop in a script is relatively easy and can be done in a simple script. My original script for running a directory of PHPUnit tests was as follows.
I had a recent requirement where I needed to temporarily replace the homepage of a website running Drupal with a simple HTML page. I wanted to do this without doing lots of changes to the site templates so I needed a solution that was easy to turn on and off and would still retain the Drupal site as it was. I found the simplest solution was to add a rule to the DirectoryIndex rule in the sites .htaccess file. Here is the rule I used.
I was at a meeting of the Manchester Web Performance Group the other day where Tom Taylor gave a talk about some of the performance testing tool he uses at Laterooms.com. He used a ruby script to set up some preferences in Firefox which then ran Selenium to open some web pages and test them with YSlow. The results of the YSlow inspection are then sent to a Show Slow server where the results can be graphed over time.
