Finishing of my elgg plugin has come to some issues, after fixing my last question I have encountered another. Apperently I am misusing or misunderstanding the use of the Created time lower and upper functions in Elgg
With the code below:
$monthSpan = (30 * 24 * 60 * 60);
$startTime = time() - $monthSpan;
$MemberDifference = elgg_get_entities_from_relationship(array(
'relationship' => 'member', //get Members
'relationship_guid' => $group->guid, //get individual guid for use
'inverse_relationship' => true,
'type' => 'user', //users are returned
'limit' => 20,
'joins' => array("JOIN {$db_prefix}users_entity u ON e.guid=u.guid"),
'order_by' => 'u.name ASC',
'relationship_created_time_lower' => $startTime, //the furthest back it will reach
'relationship_created_time_upper' => time(), //possibly unneeded, but ensures the closest date is today
'count' => true,
));
Using this function, I built it upon my way to get all of the members in the associated group, theoretically it should now grab any members that registered to that group within the last month. Unfortunately, it instead continues to grab every member in the group, regardless of the time they joined.
Does anyone have any information into where I have went wrong?
Turns out, my version of Elgg was too low, otherwise that entire block of code would work. Working Elgg 1.8, I needed to use the following code:
$MemberDifference = elgg_get_entities_from_relationship_count(array(
'relationship' => 'member',
'relationship_guid' => $Reports->guid,
'inverse_relationship' => true,
'type' => 'user',
'limit' => 20,
'count' => true,
'joins' => array("JOIN {$db_prefix}users_entity u ON e.guid=u.guid"),
'order_by' => 'u.name ASC',
'wheres' => array('r.time_created >=' . $startTime)
));
This works perfectly and brings about exactly what im looking for.

I am developing a basic forum system and have used three counter caches in it.
Two are for categories (Containers of threads), which have a reply_count and a thread_count, and the last is for the post itself which has a reply_count.
A thread is made from multiple ForumPosts, where one is a thread (is_thread = true) and the rest are replies (is_thread = false).
A part of my ForumPost code looks like this:
public $belongsTo = array(
'ForumCategory' => array(
'counterCache' => array(
'thread_count' => array('ForumPost.is_thread' => 1),
'reply_count' => array('ForumPost.is_thread' => 0)
// The line above is the one not working
)
),
'Thread' => array(
'className' => 'ForumPost',
'foreignKey' => 'forum_post_id',
'conditions' => array(
'ForumPost.is_thread' => 0
),
'counterCache' => array(
'reply_count' => array('ForumPost.is_thread' => 0)
)
),
);
public $hasMany = array(
'Reply' => array(
'className' => 'ForumPost',
'foreignKey' => 'forum_post_id'
)
);
While this works for the most part, I have noticed one piece of strange behaviour: Threads will increment a category's thread count, but replies will not increment category's reply count, although they do increment a thread's reply count.
I'm still getting used to CakePHP's ways of going about things like this so I might have missed something obvious but I've been pondering over this for a while - any help would be greatly appreciated!
Edit
The following statement is being executed:
UPDATE ... SET `ForumCategory`.`reply_count` = 8 WHERE `ForumCategory`.`id` = 0
Just realised that it was due to the fact that I wasn't setting the forum_category_id for replies to avoid redundancy, but CakePHP uses that value for inserting.
I've had to start making it set the forum_category_id on all replies, too, which is a small sacrifice I suppose.
I've a table containing more than 27,000 records. I want to fetch all data in Dropdown list. For that I've implemented cache but it seems to be not working as its getting very slow and showing blank page (Sometime browser is getting hanged).
Following is my code (I am using yiiboilerplate):
Configuration of backend/config/main.php in component array:
'cache' => array(
//'class' => 'system.caching.CMemCache',
'class' => 'system.caching.CDbCache',
'connectionID' => 'db',
),
In View page:
$dependency = new CDbCacheDependency('SELECT MAX(bank_id) FROM bank');
$bank = CHtml::listData(Bank::model()->cache(1000, $dependency)->findAll('is_active=1', array('order' => 'name')), 'bank_id', 'concatened');
echo $form->dropDownListRow($model, 'bank_id', $bank, array(
'empty' => 'Select'
));
I think 27000 records is not big data but still its getting very slow and I want to implement cache in my entire application.
Is my configuration correct? Where I am going wrong?
Thanks
I think your parameters in findAll is incorrect.
It should be:
Bank::model()
->cache(1000, $dependency)
->findAll([
'select' => 'bank_id',
'order' => 'name ASC', // if it is in ascending order
'condition' => 'is_active = 1'
]);
I don't know what concatened so I just ignored it. But you can always use scopes for your conditions.
The following query returns an array containing the proper ids, but null for all values.
If I remove the aggregation function (AVG()), it returns values (not the averaged ones of course), if I choose e.g. find('all') it returns the average, but not in the list format I want (I could work with that, but I want to try to do it with 'list' first).
$progress = $this->Trial->find('list', array(
'fields' => array(
'Trial.session_id',
'AVG(Trial.first_reaction_time_since_probe_shown) AS average_reaction_time'
),
'group' => 'Trial.session_id',
'conditions' => array(
'Trial.first_valid_response = Trial.probe_on_top',
'TrainingSession.user_id IS NOT NULL'
),
'contain' => array(
'TrainingSession' => array(
'conditions' => array(
'TrainingSession.user_id' => $this->Auth->user('id')
)
)
),
'recursive' => 1,
));
The generated SQL query returns exactly the result I want, when I send it to the DB via PhpMyAdmin.
SELECT
`Trial`.`session_id`,
AVG(`Trial`.`first_reaction_time_since_probe_shown`) AS average_reaction_time
FROM
`zwang`.`trials` AS `Trial`
LEFT JOIN
`zwang`.`training_sessions` AS `TrainingSession` ON (
`Trial`.`session_id` = `TrainingSession`.`id` AND
`TrainingSession`.`user_id` = 1
)
WHERE
`Trial`.`first_valid_response` = `Trial`.`probe_on_top`
GROUP BY
`Trial`.`session_id`
I've examined the source for find('list'). I think it's due to the "array path" for accessing the list getting screwed up when using functions in the query, but I couldn't fix it yet (or recognise my abuse of CakePHP logic).
Once I posted the question, Stackoverflow started relating the correct answers to me.
Apparently, it can't be done with 'list' without virtualFields.
I didn't expect that because it worked using the other find-types.
$this->Trial->virtualFields = array(
'average_reaction_time' => 'AVG(Trial.first_reaction_time_since_probe_shown)'
);
$progress = $this->Trial->find('list', array(
'fields' => array('Trial.session_id','average_reaction_time')
/* etc... */
));
How can you specify a max result set for Magento SOAP queries?
I am querying Magento via SOAP API for a list of orders matching a given status. We have some remote hosts who are taking too long to return the list so I'd like to limit the result set however I don't see a parameter for this.
$orderListRaw = $proxy -> call ( $sessionId, 'sales_order.list', array ( array ( 'status' => array ( 'in' => $orderstatusarray ) ) ) );
I was able to see that we do get data back (6 minutes later) and have been able to deal with timeouts, etc. but would prefer to just force a max result set.
It doesn't seem like it can be done using limit, (plus you would have to do some complex pagination logic to get all records, because you would need know the total number of records and the api does not have a method for that) See api call list # http://www.magentocommerce.com/api/soap/sales/salesOrder/sales_order.list.html
But what you could do as a work around is use complex filters, to limit the result set base on creation date. (adjust to ever hour, day or week base on order volume).
Also, since you are using status type (assuming that you are excluding more that just cancel order), you may want to think about getting all order and keep track of the order_id/status locally (only process the ones with the above status) and the remainder that wasn't proceed would be a list of order id that may need your attention later on
Pseudo Code Example
$params = array(array(
'filter' => array(
array(
'key' => 'status',
'value' => array(
'key' => 'in',
'value' => $orderstatusarray,
),
),
),
'complex_filter' => array(
array(
'key' => 'created_at',
'value' => array(
'key' => 'gteq',
'value' => '2012-11-25 12:00:00'
),
),
array(
'key' => 'created_at',
'value' => array(
'key' => 'lteq',
'value' => '2012-11-26 11:59:59'
),
),
)
));
$orderListRaw = $proxy -> call ( $sessionId, 'sales_order.list', $params);

I am stuck on pagination in CakePHP 1.3. I am trying to paginate feePayment records based on certain criteria.
feePayments belongs to Students which in turn belongs YearGroups.
I want to paginate 'unpaid' feePayments for each year group. The problem I am having is that the SQL query seems to only take into account the conditions I specified for the FeePayment model and ignores the YearGroup criteria so only overdue unpaid records are returned regardless of the year group specified.
Here is my code:
function unpaidClass($id) {
$this->paginate = array(
'FeePayment' => array ('recursive' => 1, 'conditions' => array('FeePayment.status' => 'Unpaid', 'FeePayment.due_date <= ' => date("Y-m-d"))),
'YearGroup' => array ('recursive' => 1, 'conditions' => array('YearGroup.school_year' => $id))
);
$this->set('feePayments', $this->paginate());
}
Hope this makes sense, appreciate any help.
Thanks,
Sid.
You should consider using the Containable behavior. This behavior allows you to group the necessary data you want without relaying on the "recursiveness" of your query. You can place conditions on your contained data similar to the way you would in your queries and is a more permanent way to structure data across your application instead of specifying conditions over and over again in each query.
Paginate should automatically pick up these associations when you Paginate your main model. Here's an example of what I mean here: http://cakephp.1045679.n5.nabble.com/Paginate-with-Containable-td1300971.html#a1300971
These should make your task easier.
After a lot of searching the net and reading CakePHP's documentation, here is the solution I came up with:
function unpaidClass($id) {
$this->FeePayment->unbindModel(array(
'belongsTo' => array('Student')
), $reset = 0);
$this->FeePayment->bindModel(array(
'belongsTo' => array(
'Student' => array(
'foreignKey' => false,
'conditions' => array('Student.id = FeePayment.student_id')
),
'YearGroup' => array(
'foreignKey' => false,
'conditions' => array('YearGroup.id = Student.year_group_id')
)
)
), $reset = 0);
$this->paginate = array(
'contain' => array('Student','YearGroup'),
'conditions' => array('YearGroup.school_year' => $id,
'FeePayment.status' => 'Unpaid',
'FeePayment.due_date <= ' => date("Y-m-d")));
$this->set('feePayments', $this->paginate());
}
