So I needed a quick way to convert a list of authors from “Joe A. Bloggs” into “Bloggs, Joe A.” – i.e, not separated out into firstname and lastname fields, just one field called ‘name’. I then needed another field to return a single column with the first letter of the lastname for display purposes. […]

There comes a point in life when your current hosting environment needs to scale up, and quickly. It might just be that one of your clients gets very popular very quickly, or the gradual adding of sites and resources starts to make services fail. Thankfully there are a few tricks to make life a little […]

Just a head’s up: This recent Mura CMS issue is something which could possibly apply to a wheels app: http://www.trunkful.com/index.cfm/2014/1/29/Mura-CMS-Vulnerability I’m not referring to the file manager upload bit (although that could possibly apply), but the role escalation.

The Room Booking system is now available as v 1.01; the main addition being permissions, roles and authentication. As before, I thought it might be useful to highlight a few of the thought processes behind this update, and look at some of the problems come across when beginning to think about an application which is due […]

So I admit that’s a pretty quick release cycle, but hey, I was inspired (or something). There’s some massive changes, most noticeably the addition of user authentication, roles, permissions, logging & password resets. All documentation has been moved to https://github.com/neokoenig/RoomBooking/wiki, where you can find a breakdown of all the settings, permissions, roles and upgrading instructions.

HasManycheckbox() is obviously only one way of updating these relationships. The other main way is via cunning uses of includePartial(). Let’s return to our contact’s email addresses – remember the contact ‘hasMany’ of those. We need a way to a) list their existing email addresses, b) add new ones (preferably within the same update form […]
So far we’ve setup the database tables and the models, so now we need to start thinking about getting and updating this contacts data, including the associated nested properties. Outputting a simple add/edit form should hopefully be familiar to you by now (if not I recommend checking out the cfwheels screencasts: http://cfwheels.org/screencasts ). When updating […]
Let’s look at an example call to a contact, but without any of it’s relationships. So, the simplest possible call – find me one contact row where id = 1. Well, it’s good to see our createdAt field got autofilled, and our calculated property of fullname made it through too. deletedAt is null, which is […]
