I filled a column in my database with some information, but is filling all records with all elements in each space of the column, and I would like that each element take a place in the column forming a kind of list. This is the query that I'm using.
$data = DB::table('incidencias')
->join('clientes_incid', 'clientes_incid.rif', '=', 'incidencias.rif')
->select('incidencias.rif')
->distinct()
->get();
DB::table('incidencias')->update(['resultado' => $data]);
I want to store each element of the array in a diferent row but in the same column
Can somebody help me?
I think you want every index in $data should be save as new record in database. To do that you can do this using loop.
Here edited
foreach ($data as $val) {
$exist=DB::table('incidencias')->where('resultado', $val)->count();
if($exist ==0){
DB::table('incidencias')->insert(['resultado' => $val]);
}
}
As in you query You are using update. To update you need to specify which record you want to update? You should provide some key to find record and update that. In your query you are geting record and updating all records.
I have a model download which has two three properties. Those properties are 'id' , 'user_id' , 'file_id'.
Whenever a user downloads a file a download record is created.
I want to grab all downloads that have both a unique file_id and unique user_id.
How is this accomplished.
A collection might come from a relationship and needs filtering afterward. Below is a tested working solution in laravel 5.7 and most probably in later versions also:
$unique = $collection->unique(function ($item)
{
return $item['brand'] . $item['model'];
});
Here is an article about this: http://laravel.at.jeffsbox.eu/laravel-5-eloquent-collection-methods-unique
You can use the groupBy method.
$downloads = DB::table('downloads')
->groupBy('file_id')
->groupBy('user_id')
->get();
OR
You can use the distinct method.
$downloads = DB::table('downloads')->distinct()->get();
protected function _prepareCollection()
{
$collection = Mage::getResourceModel($this->_getCollectionClass());
$collection->getSelect()->join('sales_flat_order_address', 'main_table.entity_id = sales_flat_order_address.parent_id',array('company'));
$this->setCollection($collection);
}
I use the above code to add a company field on order listing grid.
but it shows "Item (Mage_Sales_Model_Order) with the same id "1038" already exist"
Maybe try an inner join instead:
$collection->getSelect()->joinInner(
array(
'order_address' => 'sales_flat_order_address'
),
'order_address.parent_id = main_table.entity_id'
);
Also, echo out your SQL and see what the collection returns, then try and run that sql on your database. This should help you figure out what you're doing wrong.
echo $collection->getSelect()->__toString();
Keep in mind that alone won't add the column to the grid. You'll need to add the column in _prepareColumns()
EDIT:
Actually, thinking about it, an inner join probably won't help you here. The issue you have is that sales_flat_order_address contains multiple entries for every parent_id, so you need to account for duplicates by using GROUP BY or SELECT DISTINCT. try something like this:
$collection->getSelect()->joinInner(
array(
'order_address' => 'sales_flat_order_address'
),
'order_address.parent_id = main_table.entity_id'
)->group(array('entity_id', 'parent_id'));
It's not perfect, but what you're trying to do is inherently imperfect, as one order has many addresses. The alternative is to explicitly join with only the billing address, or only the shipping address.
I'm trying to use the MAX function of MySQL to retrieve the latest dates from my table.
$_updates = Mage::getModel('ticket/updates')->getCollection();
$_updates->getSelect()->columns('MAX(created) as max_created')->group(array('status_id'));
This is the resulting query:
SELECT `main_table`.*, MAX(created) AS `max_created` FROM `em_ticket_updates` AS `main_table` GROUP BY `status_id`
The problem with this is that if all the fields are included (main_table.*) it does not function correctly.
Is there a way to remove main_table.* from the query and only use specific fields?
Thanks.
A Zend trick can be used here.
$_updates->getSelect()
->reset(Zend_Db_Select::COLUMNS)
->columns('MAX(created) as max_created')
->group(array('status_id'));
NOTE:
For EAV collection you must re-add the entity_id or you will have an error when the collection is loaded.
$collection = Mage::getModel('catalog/product')
->getCollection();
$collection->getSelect()
->reset(Zend_Db_Select::COLUMNS)
->columns(array('entity_id'));
$collection
->addAttributeToSelect(array('image','small_image','thumbnail'))
->addFieldToFilter('entity_id', array('in' => $simple_ids));
Magento provide addFieldToSelect() fumctionality. Use below code to get specific field.
$Collection = Mage::getModel('showdown/votes')->getCollection();
$Collection->addFieldToSelect('id');
I recognise this is an old post but I thought I'd post an alternative solution.
I had a similar problem myself, I eventually searched through the source until I reached Zend_Db_Select After consulting the Zend Documentation (Example 8).
$select = $db->select()
->from(array('p' => 'products'),
array('product_id', 'product_name'));
Just need to use "getColumnValues"
$_updates = Mage::getModel('ticket/updates')->getCollection();
$columnValues = $_updates->getColumnValues('Your Column Name');
I want to pre-filter* data in the invoice grid visible in Magento's admin panel.
Here is a question that I asked earlier, and this one is related to the solution presented for that, hence it might act as a good explanation.
So, I am modifying the Mage_Adminhtml_Block_Sales_Invoice_Grid::_prepareCollection method so that it first fetches customer referred by the logged in admin. Then it will fetch orders from these customer(s) - ideally only the order id's - Then join this collection to sales/order_invoice_grid, to get invoices to be listed for this admin.
Based on the last answer and using these docs, following are 3 ways I have tried joining this information: (Code Sample 1)
$collection = Mage::getResourceModel('customer/customer_collection');
$collection->joinTable('sales/order_grid', 'customer_id=entity_id', array('*'));
$collection->joinTable('sales/invoice_grid', 'order_id=main_table.entity_id', array('*'));
When I do the above, I see the following error:
A joint field with this alias (0) is already declared.
#0 /var/www/magento/app/code/core/Mage/Eav/Model/Entity/Collection/Abstract.php(706): Mage::exception('Mage_Eav', 'A joint field w...')
#1 /var/www/magento/app/code/local/Myproject/Adminhtml/Block/Sales/Invoice/Grid.php(41): Mage_Eav_Model_Entity_Collection_Abstract->joinTable('sales/invoice_g...', 'order_id=main_t...', Array)
#2 /var/www/magento/app/code/core/Mage/Adminhtml/Block/Widget/Grid.php(576): Myproject_Adminhtml_Block_Sales_Invoice_Grid->_prepareCollection()
#3 /var/www/magento/app/code/core/Mage/Adminhtml/Block/Widget/Grid.php(582): Mage_Adminhtml_Block_Widget_Grid->_prepareGrid()
If I remove the second call to joinTable, the above code works, but it is not what I want.
The other method I tried is with this code:
$collection = Mage::getResourceModel('customer/customer_collection');
$collection->joinTable('sales/order_grid', 'customer_id=entity_id', array('entity_id as order_entity_id'));
$collection->joinTable('sales/invoice_grid', 'order_id=main_table.entity_id', array('*'));
Here the error appears in the second line, where I am actually trying to alias the field order.entity_id so that it does not conflict with invoice tables entity_id. However that produces an error like:
Item (Mage_Customer_Model_Customer)
with the same id "1" already exist
I only need order id's so that I can get related invoices, which suggests that I can also use joinField function, which I tried as follows:
$collection = Mage::getResourceModel('customer/customer_collection');
$collection->joinField('order_entity_id', 'sales/order_grid', 'entity_id', 'customer_id=entity_id' , null, 'left');
But it gives me the following error:
Item (Mage_Customer_Model_Customer) with the same id "1" already exist
I am looking for a solution that joins customer->invoices.
By pre-filter I mean that data listed in the grid is filtered even before anything is presented in the grid.
Ok, now my code looks like:
$collection =
Mage::getResourceModel('customer/customer_collection');
$collection->joinTable('sales/order_grid', 'customer_id=entity_id', array('entity_id' => 'order_entity_id'));
And the error that I get is:
SELECT `e`.*, `sales_flat_order_grid`.`order_entity_id` AS `entity_id` FROM `customer_entity` AS `e`
INNER JOIN `sales_flat_order_grid` ON (sales_flat_order_grid.customer_id=e.entity_id) WHERE (e.entity_type_id = '1') ORDER BY `e`.`created_at` desc, `e`.`created_at` desc LIMIT 20
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'sales_flat_order_grid.order_entity_id' in 'field list'
Here is the total of my test script. To use put it in a file at the Magento root and type it's URL directly in your browser, it is not handled by Magento's controllers. This is a good way of experimenting as it is not as influenced by other modules, page layouts, etc.
<pre><?php
require 'app/Mage.php';
Mage::app();
$collection = Mage::getResourceModel('customer/customer_collection');
$collection->getSelect()->reset('columns');
$collection->joinTable('sales/order_grid', 'customer_id=entity_id', array('order_entity_id' => 'entity_id'));
$collection->joinTable('sales/invoice_grid', 'order_id=order_entity_id', array('*'));
foreach ($collection as $invoice)
print_r($invoice->debug());
?></pre>
As with your previous question I choose to reset the initial columns because I don't believe in giving the database more work than necessary. However it's not essential, the test still succeeds without it.
If this doesn't work in your installation then we need to consider what that outside influence could be.
The error "A joint field with this alias (0) is already declared." occurs because it uses array keys as aliases. Since you have two joinTable() calls, each with an array, it is trying to use the zero-based index of both and obviously having a conflict.
So instead of
array('entity_id as order_entity_id')
try
array('entity_id' => 'order_entity_id')
to avoid the conflict.
I finally did achieve this by going from invoice->order->customer as 'Anda B' suggested. I am just pasting my solution here as a reference, but will be using this solution from clockworkgeek, since it seems much cleaner. And my solution still needs to be made cleaner by getting the 'id' of eav_attribute (agent_id) from the database at runtime, instead of hard coding it, as pasted here:
class Myproject_Adminhtml_Block_Sales_Invoice_Grid extends Mage_Adminhtml_Block_Sales_Invoice_Grid
{
const AGENT_ID_ATTRIBUTE_ID = 118;
protected function _prepareCollection()
{
$collection = Mage::getResourceModel($this->_getCollectionClass());
$collection->join('order_grid', 'order_id = order_grid.entity_id', array ('order_entity_id' => 'order_grid.entity_id'));
$collection->getSelect()->join( 'customer_entity', 'customer_id = customer_entity.entity_id', array('customer_entity_id' => 'entity_id', 'email'));
$collection->getSelect()->joinLeft( 'customer_entity_int', 'customer_entity_int.entity_id = customer_entity.entity_id AND attribute_id = ' . Myproject_Adminhtml_Block_Sales_Invoice_Grid::AGENT_ID_ATTRIBUTE_ID,
array('attribute_entity_id' => 'customer_entity_int.entity_id', 'attribute_id' , 'value'));
//Apply Desired Data Filters here
$this->setCollection($collection);
return $collection;
It gives you this error "Item (Mage_Customer_Model_Customer) with the same id "1" already exist" because a customer can have multiple orders and so could have two or more entries with the same customer id - you are creating a collection of customers and you must have unique entries in the collection.
You have to start from invoices and join them with the customers.
The simplest way I found out from the magento forum ,
In the
protected function _prepareCollection()
{
$collection = Mage::getResourceModel('customer/customer_collection')
We can use custom queries as
$collection->getSelect()->columns(array('filename' => new Zend_Db_Expr ("(SELECT filename FROM cat WHERE customer_id =e.entity_id)")));
and it works
$this->setCollection($collection);
var_dump($collection);
