Hi,
I have a strange problem.
If I output the output variable from profiler hook, it looks like this:

——————————————————
Array
(
[0] => Array
(
[type] => query
[query] => SELECT ..(something)…….
[time] => 0.000397
)
[1] => Array
(
[type] => query
[query] => SELECT ..(something)…….
[time] => 0.000994
)
[2] => Array
(
[type] => query
[query] => SELECT ..(something)…….
[time] => 0.000710
)
)
Total Doctrine time: 0.0027720928192139
Peak Memory: 9326416
——————————————————

But in my doctrine_profiler file I got this:

———————————————
php if…..

Array
(
)

Total Doctrine time: 0
Peak Memory: 9326416
—————————————

Empty array? Why?

from(’Category c, c.Forums f’)

that makes c and f aliases for the tables

Thanks for more tutorial-ly goodness. I had a question: what are the single letters in the Doctrine_Query? Like this:
“->select(’c.title, f.title, f.description’)”
Where do the letters c and f come from; what do they represent. Does this have something to do with MYSQL programming?

I had problems when PHP tried to write the ‘doctrine_profiler.php’ to my /system/logs directory. It turned out that I needed to set permissions on the /system/logs directory to 777. After that it all worked fine.

I guess it’s due to the nature of Doctrine_Collection Object. But I still don’t understand how exatly or why are the values of num_threads for the categories are 2 and 0.

Q:
When we print_r the categories after we use DQL for the query, eg:
print_r($vars['categories']->toArray(true));

Why is there another

[num_threads] => 0
)

)

at the end?

I have an idea.

How about integrating doctrine profiling with CI profiling. So that we can just call the CI’s profiler with parameter true. How about this?

I had an odd problem…

[Sat Feb 27 21:02:16 2010] [error] [client 10.5.5.197] PHP Fatal error: Call to undefined function memory_get_peak_usage() in /home/web/sites/citest.com/html/system/application/hooks/doctrine_profiler_hooks.php on line 38

…then I realized – I’m dealing with RHEL… sure enough, the base php version = 5.1.6. Yea, remember to update php to 5.2 or better.

Just a reminder.

Well, DQL itself has nice features. I prefer it over Active Records.
But also we utilized other features of Doctrine too, not just DQL.

i got a question in DQL how to pass session User id

$vars['mood'] = Doctrine_Query::create()
->select(’m.mood_name, a.id, m.account_id’)
->from(’mood m, m.account a’)
->where(’m.account_id=”7″‘)

i want to show data according to current logged user.

m.account_id=Current_User::user()->id;

it is always a goog thing to use DQL.
and with using DQL… what is the advantage in using Doctrine?

Ok! That’s it! Actually I’m using the Doctrine 1.2 version.
Thanks a lot!

Ok, I finally figured it out. It has to do with the Doctrine version.

When I first started writing this series, Doctrine 1.1 was the stable release. Now Doctrine 1.2 is out, so I assume that is what you installed. I just upgraded my install from 1.1 to 1.2 and got that same error as you guys. I am really not sure what kind of internal change they made that caused this, because 1.2 was supposed to be backwards compatible with 1.1.

Anyway, I fixed the problem. In controllers/home.php, you need to change this line:

->addSelect('COUNT(t.id) as num_threads')

to this:

->addSelect('t.id, COUNT(t.id) as num_threads')

That should fix it.

Now I will go ahead update the articles.

I had the same error message reported by Lenzjo, but unfortunately I could not figure out what triggers it. Some help?
Thanks

It’s taken me a while, but I finally got it fixed. Back in day 1, there was a problem with putting doctrine in the app plugin folder, so I put it in the sys plugin folder.

After going thru every file, in the download, and comparing mine to them the only diff was doctrine’s location. Having nothing to lose I moved it and it’s all working fine now.

I only started using CI just over a week ago, so I’m not totally familar yet with CI, but I have been using the Template library from the start with this project and was getting to think that it might be the problem.
