I am trying to make a simple query inside my model, I have already done the same thing in my controller, and so far it works.
/users/controller
$reservations = $db->fetchAll(
"SELECT TIME_FORMAT(time_start, '%H:%i') as time_start,
TIME_FORMAT(time_end, '%H:%i') as time_end
FROM bookings
WHERE datepicker = ?", [$date]);
I know that solution is not efficient, so I wanted to create a method in my function to do the same thing, however I can't find a way to enclode the time_start field with the mysql function TIME_FORMAT() using ->find() method.
update.
I have tried using virtual fields and I got only an Indirect modification of overloaded property has no effect error.
You want to use virtual fields for these. So in your case you'd want something like this:-
public $virtualFields = array(
'time_start' => "TIME_FORMAT(time_start, '%H:%i')",
'time_end' => "TIME_FORMAT(time_end, '%H:%i')"
);
These are defined within the relevant model.

i am very new in Laravel,currently working with Laravel4.I am trying to add a multiple column search functionality in my project.I can do single column eloquent search query,But honestly i have no idea how to do multiple column eloquent search query in laravel.I have two drop down menu
1.Locatiom
2.blood group.
i want to search an user having certain blood group against certain location.That is, user will select a location and blood group from those two drop down menu at a time and hit the search button.
In my database,i have two column, one contains the location and another contains the blood group of a certain user. Now,what should be the eloquent query for such a search?
Simply chain where for each field you need to search through:
// AND
$results = SomeModel::where('location', $location)->where('blood_group', $bloodGroup)->get();
// OR
$results = SomeModel::where('location', $location)->orWhere('blood_group', $bloodGroup)->get();
You can make it easier to work with thanks to the scopes:
// SomeModel class
public function scopeSearchLocation($query, $location)
{
if ($location) $query->where('location', $location);
}
public function scopeSearchBloodGroup($query, $bloodGroup)
{
if ($bloodGroup) $query->where('blood_group', $bloodGroup);
}
// then
SomeModel::searchBloodGroup($bloodGroup)->searchLocation($location)->get();
Just a sensible example, adjust it to your needs.
This is a great way but I think there is an error somewhere as laravel would not allow you to access a non-static function so instead of using
SomeModel::searchBloodGroup($bloodGroup)->searchLocation($location)->get();
you could simply use
SomeModel::BloodGroup($bloodGroup)->Location($location)->get();
take note of the searchBloodGroup has been changed to BloodGroup, that's how you will use it for all others also.
$errors = $connection->table('test_sessions_table')
->where('user_id', $user->id)
->where('status_question', 'false')->count('status_question');
in this method your code takes the following form
SQL code
select count(`status_question`) as aggregate from `test_sessions_table` where `user_id` = ? and `status_question` = ?
orWhere your code will look like this
$errors = $connection->table('test_sessions_table')
->where('user_id', $user->id)
->orWhere('status_question', 'false')->count('status_question');
SQL code
select count(`status_question`) as aggregate from `test_sessions_table` where `user_id` = ? or `status_question` = ?
Personally, I recommend using two ‘where’
//Earlier in the code, in each Model:
query = ModelName::select('table_name.*')
//Later in the code in a function in a Trait class that is always called
if ($column == 'group_by')
{
$thing_query->groupBy($value);
$thing_query->select(DB::raw('COUNT('.$value.') as count'));
}
Is there a way to append or include a separate select function in the eloquent query builder?
The actual ->select() is set earlier and then this function is called. I'd like to add the count column conditionally in this later function that has the query passed into it.
For future reference, you can use the addSelect() function.
It would be good to have in the documentation, but you'll find it here in the API: http://laravel.com/api/4.2/Illuminate/Database/Query/Builder.html#method_addSelect
Yeah you just insert the block you wanna execute as a function....according to the documentation on Parameter Grouping , you can do like so...by passing the Where a function...
This code below probably wont do what you want, but, its something for you to build off of, and play around with.
DB::table('users')
->where('name', '=', 'John')
->orWhere(function($query)
{
$query->group_by($value);
->select(DB::raw('COUNT('.$value.') as count'));
})
->get();
Try this:
$thing_query->groupBy($value)->get(DB::raw('COUNT('.$value.') as count'));
Also,if you are just trying to get the count and not select multiple things you can use ->count() instead of ->get()
I'm new to cakephp. I'm trying to search through mysql tables. I want to use nested query.
class TableController extends AppController{
.
.
public function show(){
$this->set('discouns', $this->DiscounsController->query("SELECT * FROM discoun as Discoun WHERE gcil_id = 1"));//(SELECT id FROM gcils WHERE genre = 'Shoes' AND company_name = 'Adidas')"));
}
}
Error:
Error: Call to a member function query() on a non-object
I've also tried
public function show(){
$this->DiscounsController->query("SELECT * FROM count as Count WHERE ctr_id = (SELECT id FROM ctrs WHERE genre = 'Shoes' AND company_name = 'Adidas')");
}
Error:
Error: Call to a member function query() on a non-object
File: C:\xampp\htdocs\cakephppro\myapp\Controller\CountsController.php
Please help. I've been trying this for last few hours. :/
As mentioned in the comments there are a few problems with your code.
Firstly, you are trying to call the query() method on a Controller, whereas you should be executing it on a Model, as it is models that handle database queries and the controller should simply be used to call these methods to get the data and pass them to the view.
The second thing is that you are executing a very simple SQL query raw instead of using CakePHPs built in functions <- Be sure to read this page in full.
Now for your problem, as long as you have setup your model relationships correctly and followed the correct naming conventions, this should be your code to run your SQL query from that controller:
public function show(){
$this->set('discouns', $this->Discouns->find('all', array(
'conditions' => array(
'gcil_id' => 1,
'genre' => 'shoes',
'company_name' => 'Adidas'
)
));
}
query() is not a Controller, but a Model method. That's what the error (Call to a member function on a non-object) is trying to tell you.
So the correct call would be:
$this->Discount->query()
But you are calling this in a TableController, so unless Table and Discount have some type of relationship, you won't be able to call query().
If the Table does have a relationship defined you will be able to call:
$this->Table->Discount->query()
Please not that query() is only used when performing complex SQL queries in scenarios where the standard methods (find, save, delete, etc.) are less practical.
$this->Counts->find('all',array(
'conditions' => array(
'ctrs.genre' => 'Shoes',
'ctrs.company_name' => 'Adidas'
), 'recursive' => 1
));
The above is with tables named counts and ctrs.
This is assuming you have the model set up to have some sort of relationship between the counts table and the ctrs table. It's kind of hard to tell in your code exactly what you tables are.
The CakePHP book should have all the answers you need. One of the reasons to run CakePHP over regular PHP is the FIND statement. Once you have your models set up correctly, using the find statement should be really easy.

I have a query to select all the rows from the hire table and display them in a random order.
DB::table('hire_bikes')->order_by(\DB::raw('RAND()'))->get();
I now want to be able to put
concat(SUBSTRING_INDEX(description, " ",25), "...") AS description
into the SELECT part of the query, so that I can select * from the table and a shortened description.
I know this is possible by running a raw query, but I was hoping to be able to do this using Fluent or at least partial Fluent (like above).
How can I do it?
You can actually use select AS without using DB::raw(). Just pass in an array into the select() method like so:
$event = Events::select(['name AS title', 'description AS content'])->first();
// Or just pass multiple parameters
$event = Events::select('name AS title', 'description AS Content');
$event->title;
$event->content;
I tested it.
Also, I'd suggest against using a DB:raw() query to perform a concatenation of your description field. If you're using an eloquent model, you can use accessors and mutators to perform this for you so if you ever need a limited description, you can simply output it in your view and not have to use the same query every time to get a limited description. For example:
class Book extends Eloquent
{
public function getLimitedDescriptionAttribute()
{
return str_limit($this->attributes['description'], $limit = 100, $end = '...');
}
}
In your view:
#foreach($books as $book)
{{ $book->limited_description }}
#endforeach
Example Output (not accurate to limit):
The description of this book is...
I'd also advise against using the DB facade because it always utilizes your default connection. If you're querying a secondary connection, it won't take this into account unless you actively specify it using:
DB::connection('secondary')->table('hire_bikes')->select(['name as title'])->get();
Just to note, if you use a select AS (name AS title) and you wish to update your the model, you will still have to set the proper attribute name that coincides with your database column.
For example, this will cause an exception because the title column does not exist in your database table:
$event = Events::select('name AS title')->first();
$event->title = 'New name';
$event->save(); // Generates exception, 'title' column does not exist.
You can do this by adding a DB::raw() to a select an array in your fluent query. I tested this locally and it works fine.
DB::table('hire_bikes')
->select(
array(
'title',
'url',
'image',
DB::raw('concat(SUBSTRING_INDEX(description, " ",25),"...") AS description'),
'category'
)
)
->order_by(\DB::raw('RAND()'))
->get();
select(array(DB::raw('latitude as lat'), DB::raw('longitude as lon')))
I have extended the Mage_Adminhtml_Block_Sales_Order_Grid class with a custom module to add several customer attributes (Magento EE 1.10) to the grid.
I added the custom attributes to the collection in my MyCompany_MyModule_Block_Adminhtml_Order_Grid class in the _prepareCollection() method using three joins like this:
protected function _prepareCollection()
{
$collection = Mage::getResourceModel($this->_getCollectionClass());
//get the table names for the customer attributes we'll need
$customerEntityVarchar = Mage::getSingleton('core/resource')
->getTableName('customer_entity_varchar');
$customerEntityInt = Mage::getSingleton('core/resource')
->getTableName('customer_entity_int');
// add left joins to display the necessary customer attribute values
$collection->getSelect()->joinLeft(array(
'customer_entity_int_table'=>$customerEntityInt),
'`main_table`.`customer_id`=`customer_entity_int_table`.`entity_id`
AND `customer_entity_int_table`.`attribute_id`=148',
array('bureau'=>'value'));
$collection->getSelect()->joinLeft(array(
'customer_entity_varchar_table'=>$customerEntityVarchar),
'`main_table`.`customer_id`=`customer_entity_varchar_table`.`entity_id`
AND `customer_entity_varchar_table`.`attribute_id`=149',
array('index_code'=>'value'));
$collection->getSelect()->joinLeft(array(
'customer_entity_varchar_2_table'=>$customerEntityVarchar),
'`main_table`.`customer_id`=`customer_entity_varchar_2_table`.`entity_id`
AND `customer_entity_varchar_2_table`.`attribute_id`=150',
array('did_number'=>'value'));
$this->setCollection($collection);
return parent::_prepareCollection();
}
UPDATE: While everything displays fine when viewing orders, things are not fine when I try to search / filter orders by any of the text join fields (index_code or did_number). The result is a SQL error: "SQLSTATE[23000]: Integrity constraint violation: 1052 Column 'store_id' in where clause is ambiguous."
This problem also exists if I remove all but one of the leftJoin() statements, so something is going wrong with both (either) of the joins with the customer_entity_varchar table.
As now there are two columns with the name store_id, you have to specify filter_index when you add the column to the grid:
$this->addColumn('store_id', array(
...
'filter_index'=>'main_table.store_id',
));
So that it knows which one you are referring while filtering.
I hope it helps!
More than likely it is because you are joining customer_entity_varchar_table twice.
$collection->getSelect()->joinLeft(array(
'customer_entity_varchar_table'=>$customerEntityVarchar),
'`main_table`.`customer_id`=`customer_entity_varchar_table`.`entity_id`
AND `customer_entity_varchar_table`.`attribute_id`=149',
array('index_code'=>'value'));
$collection->getSelect()->joinLeft(array(
'customer_entity_varchar_2_table'=>$customerEntityVarchar),
'`main_table`.`customer_id`=`customer_entity_varchar_2_table`.`entity_id`
AND `customer_entity_varchar_2_table`.`attribute_id`=150',
array('did_number'=>'value'));
You may want to combine those, you can also try and print the SQL to see what the Query looks like:
$collection->getSelect()->getSelectSql();

The problem appears to exist in two different places. One case is if logged in as a user with a single store, the other as a user who can filter various stores.
Single store user
The solution I went with was to override the addAttributeToFilter method on the collection class. Not knowing exactly what changing the Enterprise_AdminGws_Model_Collections::addStoreAttributeToFilter method would affect other behavior I wanted to avoid that, and I found adding a filter index in Mage_Adminhtml_Block_Sales_Order_Grid as Javier suggested did not work.
Instead I added the following method to Mage_Sales_Model_Resource_Order_Grid_Collection:
/**
* {#inheritdoc}
*/
public function addAttributeToFilter($attribute, $condition = null)
{
if (is_string($attribute) && 'store_id' == $attribute) {
$attribute = 'main_table.' . $attribute;
}
return parent::addFieldToFilter($attribute, $condition);
}

Multi-store user
If a user can filter orders by store at admin/sales_order, the following change is also needed to Mage_Adminhtml_Block_Sales_Order_Grid around line 75:
if (!Mage::app()->isSingleStoreMode()) {
$this->addColumn('store_id', array(
'header' => Mage::helper('sales')->__('Purchased From (Store)'),
'index' => 'store_id',
'type' => 'store',
'store_view'=> true,
'display_deleted' => true,
'filter_index' => 'main_table.store_id',
));
}

I had the same bug, after grepping the code, I finally found the troublemaker which is in the Enterprise_AdminGws_Model_Collections class at line ~235:
/**
* Add store_id attribute to filter of EAV-collection
*
* #param Mage_Eav_Model_Entity_Collection_Abstract $collection
*/
public function addStoreAttributeToFilter($collection)
{
$collection->addAttributeToFilter('store_id', array('in' => $this->_role->getStoreIds()));
}
You have to replace 'store_id' by 'main_table.store_id', of course you'll have to extend that particular method in your own rewrite to stick into Magento guidelines :p
Hope it helps!
