I’ve been having fun implementing my first cut at Image/File management for Gravl, and along the way I’ve learnt about LightBox and the Scriptaculous InPlaceEditor stuff. First up, I needed a way of doing an image preview, so I could see what all of those PNGs really meant. Lightbox gives you a great way of “overlaying” the preview image as a popup without the need to refresh the page. Very snazzy. I followed the instructions [...]

If you haven’t had a chance to play with the RichUI plugin, you’ve got to take it for a spin – it’s just fantastic. I’ve been meaning to implement autocomplete for Gravl tags on new blog entries, and with the RichUI plugin (which uses Yahoo Autocomplete under the hood) it’s a total snack. First you declare the RichUI taglibs in your gsp file (note: I’m using the undocumented delimChar setting so that I separate multiple [...]

Thanks to a fantastic tip from Karl on yesterday’s post, I’ve got the searchable plugin up and running on my Grails-RC3 install! Here’s the fix from Karl: i‘ve got a working Searchable-0.4-SNAPSHOT wo. npe, this is working with the RCs too. In the plugin‘s java directory u need to slightly modify the org/codehaus/groovy/grails/plugins/searchable/compass/SearchableCompassUtils.java file. Here is the “patched” version: http://rafb.net/p/prsZip92.html (nopaste url) So I patched my version, and I’m up and running. Getting Gravl converted [...]

I’ve just finished adding fulltext search to Gravl, and, while is still needs some more CSS tweaks, it’s working just great. I took the chance to have a good look at the Searchable plugin and it looks awesome! Sadly, it just kept NPEing at me and complaining that it couldn’t find java.lang.Class! Perhaps it’s a victim of the RC-flux, no doubt it will resurface as 1.0 settles in. Anyways, I ripped the SearchService out of [...]

Continuing my obsession with the power of Grails filters, it was time to add some referer tracking and ipaddress Geocoding to Gravl to see where people are coming from. So I created a new RefererFilters class in conf and I was up and running. I already had a little CacheService happening, so I created a new 24 hour cache, scooped up some interesting browser header data, and squirrelled it away for later: // Scoop up [...]

Grails Filters open up a whole new world of opportunity for jumping into the request pipeline to do your own custom processing. I’m really excited about getting Referer tracking real soon now, since I’ve learned the basics of Filters when I implemented Gravl’s very basic security model. The Grails community is working on some first class plugins for Acegi and JSecurity, but for if your security model is coarse grain (authenticated users can do this, [...]
