In this example a have one blog that have multiple posts.
How can I add elements to a collection and keep everything a collection:
$post = collect(['title' => 'Hello', 'content' => 'world']);
$blog->posts->push($post);
And then access it with $blog->posts but instead I have to access it with $blog['posts'].
I have tried:
// First way
$blog = collect(['posts']);
$blog->posts->push($post);
// Second way
$blog = collect();
$blog->put('posts' [$post]);
// Third way
$blog = collect();
$blog->put('posts', collect([]));
$blog->posts->push($post);
I think you want to append new Article to the blog's articles.
In this case you have to do the following, in the below example:
$blog = Blog::find(1);
dump($blog->articles); // Two items retrieved
// New article
$newArticle = new Article([
'title' => 'Article Three',
'content' => 'Article Three',
]);
// Prepend to articles as a collection
$blog->articles->prepend($newArticle);
// Save it into DB [If you want]
// $blog->articles()->save($newArticle);
dd($blog->articles); // The collection updated with the new item.

I wish to add more values to product table in cs- cart documents.
In my country we have requirements for tax name for each product included in invoice.
How can I add value of {{o._tax_name}} into product table in documents invoice and order summary in cscart ?
You could modify or add inside your own addon at path:
/app/addons/my_changes/schemas/snippets/order_products_table.post.php
the code that looks something like this:
$schema['custom_tax_name'] = array(
'class' => '\Tygh\Template\Document\Variables\GenericVariable',
'data' => function (\Tygh\Template\Snippet\Table\ItemContext $context) {
$data = array();
$product = $context->getItem();
$data['tax_name'] = getTaxName($custom_val); //you could have function here to get whatever your needs are
return $data;
},
'arguments' => array('#context', '#config', '#formatter'),
'attributes' => array(
'tax_name'
)
);
After this, clear your cache and then you will see inside Menu: Documents - order.invoice the new value that already created, like this:
{{ custom_tax_name.tax_name }}
I'm using composer require gloudemans/shoppingcart I am not sure how to maintain amount.
When i'm using one route that says add item when i'm using this route adding multiple item
How can i conditionally setup to add item in cart if this is unique
public function bookItem($id) {
$item = Item::where([
'status' => '1',
'id' => $id
])->first();
$product = Cart::add($item->id, $item->name, 1, $item->price); // This should not call always if it has not generated a row id then it should call
Cart::update($product->rowId, ['price' => 200]); // Will update the price if it is differ
return redirect()->route('book.item', ['id' => $item->id]);
}
I am not sure how to manage it. please guide
Looks like the package has a getContents() function that gathers all items into a collection. It also has a search(Closure) function that calls getContents() and then uses Laravel's filter function on the collection and returns the result.
$search = Cart::search(function($key,$value) use ($item) {
return $value === $item->id;
})->first();
if(!empty($search)){
Cart::update($search->rowId, ['price' => 200]);
}
else {
$product = Cart::add($item->id, $item->name, 1, $item->price);
}
Definitely check out the Laravel collection docs if you aren't familiar. This is the entey on filters:
https://laravel.com/docs/5.8/collections#method-filter
I can't fetch last id of created data from related model.
I tried to use $alacarte->id but it doesnt get the right ID of the model.
$order = array(
'os_id' => $orderSlip->id,
'group_id' => $menu['group_id'],
'size' => $menu['size'],
);
$alacarte = $this->menu->find($menu['id']);
$alacarte->orders()->create($order)->save();
return $alacarte->id;
I expect the output of the last created order to be the ID of Model\Order, but the actual output is the ID of the Model\Menu.
[Solved]
I just removed save() after creation.
$menu = $alacarte->orders()->create($order)->save()
changed to
$menu = $alacarte->orders()->create($order)
return $menu->id
i have an array as follows
'topic' =>
array (
'id' => 13,
'title' => 'Macros',
'content' => '<p>Macros. This is the updated content.</p>
',
'created_at' => '2014-02-28 18:36:55',
'updated_at' => '2014-05-14 16:42:14',
'category_id' => '5',
'tags' => 'tags',
'referUrl' => '',
'user_id' => 3,
'videoUrl' => '',
'useDefaultVideoOverlay' => 'true',
'positive' => 0,
'negative' => 1,
'context' => 'macros',
'viewcount' => 60,
'deleted_at' => NULL,
)
I would like to use this array and convert/cast it into the Topic Model . Is there a way this can be done.
thanks
Try creating a new object and passing the array into the constructor
$topic = new Topic($array['topic']);
For creating models from a single item array:
$Topic = new Topic();
$Topic->fill($array);
For creating a collection from an array of items:
$Topic::hydrate($result);
Here is a generic way to do it, not sure if there is a Laravel-specific method -- but this is pretty simple to implement.
You have your Topic class with its properties, and a constructor that will create a new Topic object and assign values to its properties based on an array of $data passed as a parameter.
class Topic
{
public $id;
public $title;
public function __construct(array $data = array())
{
foreach($data as $key => $value) {
$this->$key = $value;
}
}
}
Use it like this:
$Topic = new Topic(array(
'id' => 13,
'title' => 'Marcos',
));
Output:
object(Topic)#1 (2) {
["id"]=>
int(13)
["title"]=>
string(6) "Marcos"
}
It seems that you have data of an existing model there, so:
First, you can use that array to fill only fillable (or not guarded) properties on your model. Mind that if there is no fillable or guarded array on the Topic model you'll get MassAssignmentException.
Then manually assign the rest of the properties if needed.
Finally use newInstance with 2nd param set to true to let Eloquent know it's existing model, not instantiate a new object as it would, again, throw an exception upon saving (due to unique indexes constraints, primary key for a start).
.
$topic = with(new Topic)->newInstance($yourArray, true);
$topic->someProperty = $array['someProperty']; // do that for each attribute that is not fillable (or guarded)
...
$topic->save();
To sum up, it's cumbersome and probably you shouldn't be doing that at all, so the question is: Why you'd like to do that anyway?
Look at these two available methods in L5 newInstance and newFromBuilder
e.g with(new static)->newInstance( $attributes , true ) ;
I would likely create the new instance of the object and then build it that way, then you can actually split some useful reusable things or defaults into the model otherwise what's the point in pushing an array into a model and doing nothing with it - very little besides for normalization.
What I mean is:
$topic = new Topic();
$topic->id = 3489;
$topic->name = 'Test';
And the model would simply be a class with public $id;. You can also set defaults so if you had like resync_topic or whatever property, you can set it as 0 in the model rather than setting 0 in your array.
I came across this question looking for something else. Noticed it was a bit outdated and I have another way that I go about handling the OPs issue. This might be a known way of handling the creation of a model from an array with more recent versions of Laravel.
I add a generic constructor to my class/model
public function __construct(array $attributes = [])
{
parent::__construct($attributes);
}
Then when I want to create a new instance of the model from an array I make a call like this
$topic = new Topic($attrs);
// Then save it if applicable
$topic->save(); // or $topic->saveOrFail();
I hope someone finds this helpful.
When creating a product I can use the following via the API:
$newProductData = array(
'name' => (string)$stockItem->STOCK_DESC,
'websites' => array(1,2), // array(1,2,3,...)
'short_description' => (string)$stockItem->STOCK_DESC,
'description' => (string)$stockItem->LONG_DESC,
'status' => 1,
'weight' => $stockItem->WEIGHT,
'tax_class_id' => 1,
'categories' => array(3108),
'price' => $stockItem->SELL_PRICE
);
$my_set_id = 9; // Use whatever set_id you want here
$type = 'simple';
$mc = new Mage_Catalog_Model_Product_Api();
$mc->create($type, $my_set_id, $stockItem->STOCK_CODE, $newProductData);
When I look into the $mc->create call I see that it does this:
foreach ($product->getTypeInstance(true)->getEditableAttributes($product) as $attribute) {
}
which indicates there is a list of attributes which can be edited against an object.
How do I find these? Is there a specific place this information is found?
Edit: I just did:
Mage::log($product->getTypeInstance(true)->getEditableAttributes($product));
and had a look at the results. It seems all the editable attributes are there which can be found under [attribute_code] => but I would still like a better method of knowing where to look to get this list.
This will depend entirely on the attribute set of the product you're trying to edit, and the configuration of each individual attribute. There's no place in the UI that will list these attributes out for you. Your best bet is to run some custom code for your product
$product = Mage::getModel('catalog/product')->load($product_id);
foreach ($product->getTypeInstance(true)->getEditableAttributes($product) as $code=>$attribute)
{
var_dump($code);
}
Here's how to track this information down. If you jump to the getEditableAttributes method
#File: app/code/core/Mage/Catalog/Model/Product/Type/Abstract.php
public function getEditableAttributes($product = null)
{
$cacheKey = '_cache_editable_attributes';
if (!$this->getProduct($product)->hasData($cacheKey)) {
$editableAttributes = array();
foreach ($this->getSetAttributes($product) as $attributeCode => $attribute) {
if (!is_array($attribute->getApplyTo())
|| count($attribute->getApplyTo())==0
|| in_array($this->getProduct($product)->getTypeId(), $attribute->getApplyTo())) {
$editableAttributes[$attributeCode] = $attribute;
}
}
$this->getProduct($product)->setData($cacheKey, $editableAttributes);
}
return $this->getProduct($product)->getData($cacheKey);
}
You can see that this method gets a list of all the attributes set on a particular product.(i.e. All the attributes that are a member of the product's attribute set). Once it has this list, it goes through each and checks if its apply_to property matches the type id of the current product.
The Apply To attribute is set at
Catalog -> Attributes -> Manage Attributes -> [Pick Attribute]
This form field updates the database table catalog_eav_attribute. If you run the following query you can see examples of this value as is stored
select attribute_id, apply_to from catalog_eav_attribute where apply_to is NOT NULL;
75 simple,configurable,virtual,bundle,downloadable
76 simple,configurable,virtual,bundle,downloadable
77 simple,configurable,virtual,bundle,downloadable
78 simple,configurable,virtual,bundle,downloadable
79 virtual,downloadable
So, get your product's attribute set. Get a list of attributes in that set. Compare the value of the attribute's apply_to field vs. the value of your product's type_id. That will let you build a list of these attributes.
