Forums don't really work

Hi:
I'm almost done with my web based on Beerhouse project and will be soon publishing so was looking at some issues other people have with actual webs.

Referring to another poster's complaint regarding his own website, I went to:
http://www3.gamhan.com/BeerHouse/Default.aspx

where they have put the Beerhouse online.

I tried posting in the forums. As this other poster had complained of with his site, the post does not show up. The title to the posts shows, but not the text of the posts. You can see where I "Rae88" tried posting in two different forums and tho the heading/Title appears, the post doesn't!

Has the author furnished any fix to this? I'd like to get my code corrected before I go online if possible.

Rachel,

This issue is related to the clearing of the posts cache. Have a look at the sections where the cache is cleared (when adding/amending posts) and you'll need to add a few additional sections there. I'm not at a machine that has the code otherwise i'd post it. However, later today, I'll be at home and will be able to post the updated code for you.

I had this issue too, hence putting the fix in place. You may discover the fix yourself before i post it and if so, drop the fix up here for others to see.

cheers for now

Hi Jimi:
Please do post it when you get a chance. (I'm currently working on trying to conclude some other issues with my project now so will not be discovering the fix for this anytime soon.)

I'll tell that other poster to look here later and view your post.

Thanks a lot,

Rachel

Rachel,

You need to add the following code to the InsertPost() method of BLL/Forums/post.cs in the same section as the other BizObject.PurgeCacheItems stuff.

// jbt frig to empty cache
BizObject.PurgeCacheItems("Forums_Thread");

It's not very 'clever' and to be honest, I now use a different cacheing scheme in any TBH architecture based sites that I now do. However, this is what I last did when i was using it a year or so back.

Let me know if this fixes it for you.

Thanks a bunch Jimi:
I haven't yet deployed my site but I will make that change and hope it works when I'm actually on line.

Jimi -

I would be interested learning how you're implementing caching now. As my TBH site becomes more complex the 'PurgeCache' method has been a frequent source of frustration, but I haven't yet developed a better caching scheme than the one presented in TBH.

Thanks.

Scott,

Basically, I generate my DAL/BLL/ (basic CRUD UI) from a site generator that i've been developing and as a result, came up with several (imo) improvements to the caching sheme. basically, the bits that can cause issues are places where you have lists that may have foreign keys etc and something there changes, or single entities where a change occurs but supporting lists don't get cleared. The best way to see this in action may actually be to download the site generator and run it against the TBH database. You'll then get an idea of the new 'improved' caching scheme from the resulting code.

The nice thing is that the site generator is wholly based on the good principles of TBH architecture but with a few of the wrinkles ironed out. I use it on most projects these days and it has saved me both a ton of effort as well as saving in the frustration normally associated in handcoding this 'plumbing' set of layers.

Grab yourself a copy from:

Announce: Flixon Site Generator V2 now available

enjoy...

Jimi -

I haven't taken the time to investigate Flixon yet, but you've given me a good reason to check it out now. I know you're a big proponent of Flixon so I'm sure it will be worth the effort. Thanks for the tip!
