Trying to figure out how to build a query in CakePHP where I can select all Events that are between X and Y dates (user-entered dates).
The problem lies in that the Event doesn’t have the dates in it’s table.
Event hasMany Schedule
Schedule belongsTo Event
Schedule hasMany Date
Date belongsTo Schedule
Events table: details of the event – name, location, description…etcSchedules table: start and end date with repeat optionsDates table: the actual dates of the event created from the data inSchedules
So – I actually need to select any Events that have at least one Date entry between the X and Y dates.
I also need to be able to display the dates with the event data.
Edit (REVISED):
I’ve tried this, but it appears to be retrieving the events regardless of the Date, but only retrieving the Date info if the date falls within the range:
$this->Event->Behaviors->attach('Containable');
$events = $this->Event->find('all', array(
'limit'=>5,
'order'=>'Event.created DESC',
'contain' => array(
'Schedule' => array(
'fields'=>array(),
'Date' => array(
'conditions'=>array(
'start >=' => $start_date,
'start <=' => $end_date,
)
)
)
),
));
*Just to clarify – Date.start and Date.end are always the same Date – they just also include a time (both datetime fields) – hence why I’m checking “start” against both.
I’ve tried using containable, I’ve tried unbind/bindModel..etc – I must be doing something wrong or off-track.
Something to keep in mind – once I figure out how to get the Events based on the Date, I also need to add on other conditions like Event Types and more – not sure if this would affect the answer(s) or not.
UPDATE:
Here’s what I’m using that seems to work – also seems very ugly – any thoughts?:
function getEvents($opts = null) {
//$opts = limit, start(date), end(date), types, subtypes, subsubtypes, cities
$qOpts['conditions'] = array();
//dates
$qOpts['start'] = date('Y-m-d') . ' 00:00:00';
if(isset($opts['start'])) $qOpts['start'] = $opts['start'];
$qOpts['end'] = date('Y-m-d') . ' 23:59:59';
if(isset($opts['end'])) $qOpts['end'] = $opts['end'];
//limit
$qOpts['limit'] = 10;
if(isset($opts['limit'])) $qOpts['limit'] = $opts['limit'];
//fields
//$qOpts['fields'] = array('Event.id', 'Event.name', 'Event.slug', 'City.name', 'Date.start');
// if(isset($opts['fields'])) $qOpts['fields'] = $opts['fields'];
//date conditions
array_push($qOpts['conditions'], array(
"Date.start >=" => $qOpts['start'],
"Date.start <=" => $qOpts['end'],
));
//cities conditions
if(isset($opts['cities'])) {
if(is_array($opts['cities'])) {
$cityConditions['OR'] = array();
foreach($opts['cities'] as $city_id) {
array_push($cityConditions['OR'], array('OR'=>array('Venue.city_id'=>$city_id, 'Restaurant.city_id'=>$city_id)));
}
array_push($qOpts['conditions'], $cityConditions);
}
}
//event types conditions
//$opts['event_types'] = array('1');

array_push($qOpts['conditions'], $eventSubTypeConditions);
}

//event sub sub types conditions
if(isset($opts['event_sub_sub_types'])) {
if(is_array($opts['event_sub_sub_types'])) {

array_push($eventSubSubTypeConditions['OR'], array('EventSubSubTypesEvents.event_sub_sub_type_id' => $event_sub_sub_type_id));

array_push($qOpts['conditions'], $eventSubSubTypeConditions);

GROUP_CONCAT to the rescue!!! Long story short – I needed to return Events with their many Dates (with being able to query against different HABTM tables) – but when I tried, I’d either get way too many events (one for each date…etc) or I’d use GROUP BY, and not get all the dates. The answer… still use GROUP BY, but combine the Dates into a single field using GROUP_CONCAT:
I’m posting a lot of code – feel free to browser if you got stuck like I did.

Hope this helps someone. Feel free to point out any issues w/ my code – I always like to improve. But for now, I’m dancing in circles because it WORKS!!! Now that it works, I’m going to go back in and try to clean up those ORs like @bfavaretto mentioned.
