I'm trying to put my catalog in cache by team.
Price may vary by team.
But if the price is not set for a product I need to send the "default" team value", and can't find an easy way to do this.
$teams = Team::all();
foreach ($teams as $team) {
$teamId = $team->id;
$catalog = Cache::rememberForever('catalog-' . $team->id, function () use ($teamId) {
$catalog = Category::with(['products.prices' => function ($q) use ($teamId) {
$q->where("team_id", $teamId); // and if no result $q->where("team_id",1);
}])->all();
return $catalog;
});
}
I was searching with queries like $q->whereNotExist, but I can't find a way to do it correctly. They may be some other way to do this via Product or Price model (and mutator), but I also stuck here.
Thank you.

I have two models customer and orders. They are already fecthed separately
$customers = customer::all();
$orders = orders::all();
customerID=1 has orderID : 1, 2,4 customerID=2 has orderID : 3,5,9
They are related (hasMany, belongsTo) but the problem is inside my for a certain reason they are separated but I want to send them as response in API using toJson or ToArray as one data having the orders nested to their correct customers.
How can I achieve that linking to have at the end one variable $customersWithOrders that should be transformed to JSON ?
I am using laravel 5.5
I don't know what the context is. Defining relationships as other answers mentioned is a good solution.
In addition, I recently read a pretty good article about this specific scenario.
So you can also do something like this, if you have already retrieved customers and orders:
$customers = Customer::all();
$orders = Order::all();
return $customers->each(function ($customers) use ($orders) {
$customer->setRelation('orders', $orders->where('customer_id', $customer->id));
});
If you already have a relation you just use it. For example, in model Customer.php:
public function orders()
{
return $this->hasMany(Order::class);
}
Then you'd get customer orders by calling $customer->orders
If you already have defined relations, you can simply fetch data with eager loading
// in customer model
public function orders()
{
return $this->hasMany(orders::class, 'orderID');
}
// in controller
$customersWithOrders = customer::with('orders')->get();
return response()->json(['customersWithOrders' => $customersWithOrders]);
// in js
for (let customer in response.customersWithOrders){
let orders = customer.orders
}
Let's take the example from the doc : https://laravel.com/docs/5.7/eloquent-relationships#many-to-many-polymorphic-relations it's easy to get all posts with their tags count doing Post::withCount('tags')->get().
But how to get all tags with their usage count ? To have them ordered by most used / less used.
If I do Tag::withCount(['video', 'post'])->get() I will have 2 attributes videos_count and posts_count. In my case I would like a unique taggables_count that will be the sum of the two. In a perfect world by adding a subselect querying the pivot table.
I would suggest simply doing the call you already did, which is Tag::withCount(['video', 'post'])->get(), and add this to your Tag model:
// Tag.php
class Tag
{
...
// Create an attribute that can be called using 'taggables_count'
public function getTaggablesCountAttribute()
{
return $this->videos_count + $this->posts_count;
}
...
}
and then in your loop (or however you use the items in the collection):
#foreach($tags as $tag)
{{ $tag->taggables_count }}
#endforeach
This setup requires you to get the Tags with the withCount['video', 'post'] though. If you do not, you will likely get 0in return for $tag->taggables_count.
If you're really concerned about speed, you would have to create the query manually and do the addition in there.
So after more searching I find out there is no way to do it with only in one query due to the fact that in mysql we can't do a select on subselet results. So doing Tag::withCount(['videos', 'posts']) and trying to sum in the query the videos_count and posts_count will not work. My best approach was to create a scope that read results in the pivot table :
public function scopeWithTaggablesCount($query) {
if (is_null($query->getQuery()->columns)) {
$query->select($query->getQuery()->from . '.*');
}
$query->selectSub(function ($query) {
$query->selectRaw('count(*)')
->from('taggables')
->whereColumn('taggables.tag_id', 'tags.id');
}, 'taggables_count');
return $query;
}
To use it :
$tags = Tag::withTaggablesCount()->orderBy('name', 'ASC')->get();
So now we have a taggables_count for each tag and it can be used to order by. Hope it can help others.
I have areas. Each area have N curses
So, each curse belongsTo only one area.
My class
class Area extends Model
{
public function curses()
{
return $this->hasMany('App\Curse');
}
}
My Controller
public function getCursesByAreaId()
{
$areaId = Input::get('areaId'); //ID of selected Area
//area_id is a field of table CURSE. A FK to Area.
$areas = Area::with('curses')->where('area_id', $areaId)->get();
foreach($areas as $area)
{
var_dump($areas);
}
}
Curse Model
class Curseextends Model
{
protected $fillable =
[
'description',
'area_id'
];
}
Using the laravel's debugbar, I see that the query being executed is this:
select * from "areas" where "area_id" = '2'
Isn't it supose to run the relational query ? (with the joins)
Already checked if I'm receiving the right id and it's ok.
the problem is that it's bringing no data at all.
You need something like the following:
$areas = Area::whereHas('curses', function($query) use ($areaId) {
$query->where('area_id', $areaId);
})
->with('curses')
->get();
The whereHas is required only if you want to get the areas that has matching curses.
But, I think you can do it like this way if you only need the related curses because one curse only belong to a single area so, if have the area then you'll get all the curses attached to it:
$area = Area::with('curses')->find($areaId); // Single area
// Access the curses
$curses = $area->curses; // collection of curses
I think you are using relational area_id which is present in curse table, try retrieving the ID of area by id not by area_id, something like this:
$areas = Area::where('id', $areaId)->with('curses')->get();
Hope you get the solution.
Try this :
$areas = Area::whereHas('curses', function($area_query) use ($area_id) {
$area_query->where('area_id', $area_id)
})
->with('curses')
->get();
I'm trying to create a tag cloud in Laravel 4.1, tags can belong to many posts, and posts can have many tags. I'm using a pivot table to achieve this (post_tag).
So far I've come up with this to fetch the tags and check how many times it's used:
public static function tagCloud($tags, $max = 10) {
foreach($tags->toArray() as $tag) {
$count = DB::table('post_tag')
->where('tag_id', $tag['id'])
->count();
$cloud[$tag['slug']] = $count;
}
sd($cloud);
}
I pass Tag::all() to the above function. Obviously that's going to fire a crazy amount of queries on the database, which is what I'm trying to avoid. Normally you'd use eager loading to fix this problem, but it seems the documentation does not mention anything about eager loading pivot tables in combination with aggregates.
I hope someone can shine a light on how to optimize this current function or can point me in the right direction of a better alternative.
Sometimes it's just hard reduce them, but Laravel Cache is your friend:
$users = DB::table('users')->remember(10)->get();
It will remember your query for 10 minutes.
I believe you have a many-to-many relationship with posts in your tags table like this:
public function posts()
{
return $this->belongsToMany('Post');
}
So, you are able to do something like this:
$tags = Tag::with('posts')->get();
Then you may loop though the tags to find out how many posts each tag contains, like this:
foreach($tags as $tag) {
$tag->posts->count();
};
So, you may write your function like this:
public function scopeTagCloude($query) {
$cloud = [];
$query->with('posts')->get()->each(function($tag) use (&$cloud) {
$cloud[$tag['slug']] = $tag->posts->count();
});
return $cloud;
}
You may call this function like this:
$tagCloude = Tag::tagCloude();
If you dd($tagCloude) then you'll get something like this (example is taken from my blog app):
array (size=4)
'general' => int 4
'special' => int 5
'ordinary' => int 5
'extra_ordinary' => int 2
I want to check if there is a sales promotion on the product then stick the promotion label on that product on category list page. But I don't know how to loop through all the shopping cart rules and retrieve the products/categories associated to each rule.

Thanks seanbreeden, but I can't pull the skus from $conditions. var_dump($conditions); shows this:

but when I loop through $conditions i.e.
$rules = Mage::getResourceModel('salesrule/rule_collection')->load();
foreach ($rules as $rule) {
$conditions = $rule->getConditionsSerialized();
foreach ($conditions as $condition) {
var_dump($condition);
}
}
it doesn't show anything so don't really know how to pull skus here.
EDIT2
As Alaxandre suggested, I'm not using unserialized approach. I'm doing it like this now:
$rules = Mage::getResourceModel('salesrule/rule_collection')->load();
foreach ($rules as $rule) {
if ($rule->getIsActive()) {
//print_r($rule->getData());
$rule = Mage::getModel('salesrule/rule')->load($rule->getId());
$conditions = $rule->getConditions();
$conditions = $rule->getConditions()->asArray();
foreach( $conditions['conditions'] as $_conditions ):
foreach( $_conditions['conditions'] as $_condition ):
$string = explode(',', $_condition['value']);
for ($i=0; $i<count($string); $i++) {
$skus[] = trim($string[$i]);
}
endforeach;
endforeach;
}
}
return $skus;
And then checking in list page if sku matches within $skus array then show the label. But again there are limitation with this approach as well. I'm think of another approach (I'm not sure if thats is possible).
Thinking of creating a new table (to save the sales rules products).Everytime save the sales rule, catch the save rule event and update the table with Rule name and all the associated products. Then on the list page check that table, if products exist in the table, show the appropriate label. Now I think the event is adminhtml_controller_salesrule_prepare_save (not 100% sure) but I don't know how to get the sku from the rule condition in the observer to save in the new table.
I would suggest you to do it like this. When you had a product to cart, each rules are checked to calculate the final price and reduction. You can know which rules are applied to each item of your cart. In the table sales_flat_quote_item you have the column applied_rule_ids. I think you can access to this in php, by a function getAllItemsInCart or something like this (you have to find out). After you do $item->getAppliedRuleIds() and finally you can get the name of the rule apply to an item (product).
Good luck :)
Edit:
I read again your request and I think my answer doesn't fit with your request.
Your case is even more complicated. For each product on your catalog page you have to apply all the rules of your website. But Mage_SalesRule_Model_Validator process expect item and not product...
If you have lot of rules this task will slow down your catalog and this is really not good! The best would be to cache this result of the rules label in the database, may be in the table catalog_category_product or... (and even better to generate this cache automatically).
Edit2:
Other possibility would be to have a new field in rule creation where you set manually the related products (sku). You save this data in the table salesrule or in a new table salesrule_related_sku.
Then when you display the catalog you check for the sku and if the rule still active.
This solution would be the easiest one :-)
You could pull the getMatchingProductsIds from /app/code/core/Mage/CatalogRule/Model/Rule.php and compare them with the skus displayed on the category list page.
$catalog_rule = Mage::getModel('catalogrule/rule')->load(1); // ID of your catalog rule here, or you could leave off ->load(1) and iterate through ->getCollection() instead
$catalog_rule_skus = $catalog_rule->getMatchingProductIds();
hth
EDIT
Here's a way to get the serialized conditions:
$rules = Mage::getResourceModel('salesrule/rule_collection')->load();
foreach ($rules as $rule) {
$conditions = $rule->getConditionsSerialized();
var_dump($conditions);
}
EDIT 2
There would have to be a better way to do this. The only way I could pull that data was to unserialize then iterate with foreach through each layer. Anyone have any better ideas for this? This works but is very sloppy.
$rules = Mage::getResourceModel('salesrule/rule_collection')->load();
foreach ($rules as $rule) {
if ($rule->getIsActive()) {
$conditions = $rule->getConditionsSerialized();
$unserialized_conditions = unserialize($conditions);
$unserialized_conditions_compact = array();
foreach($unserialized_conditions as $key => $value) {
$unserialized_conditions_compact[] = compact('key', 'value');
}
for ($i=0;$i<count($unserialized_conditions_compact);$i++) {
if (in_array("conditions",$unserialized_conditions_compact[$i])) {
foreach($unserialized_conditions_compact[$i] as $key => $value) {
foreach($value as $key1 => $value1) {
foreach($value1 as $key2 => $value2) {
foreach($value2 as $key3 => $value3) {
$skus[] = explode(",",$value3['value']);
}
}
}
}
}
}
}
}
var_dump($skus);
The rules are associated to all product for a website. There is no rules set for a specific products/categories from the database point of view. For each product in the cart, Magento will validate all the rules you have for a website. This operation is done in the class Mage_SalesRule_Model_Validator. The only way to solve your request is to extend the function process from this class (at least I think so :p).
I wanted the same thing as you want. I wanted to get associated SKUS, Category Ids and any other conditions value to generate Google feeds to be used in Google merchant promotions.
I have used the recursive function to reach to last children of the condition and fetch its value.
I am checking based on the attribute value of the condition. If an attribute value is blank then go one step down and check if attribute value present and if so then fetch the value of it otherwise continue to go down.
Here is the code that I used to fetch values. Which will also work for the case, when two conditions are on the same level.
public function get_value_recursively($value){
foreach($value as $key => $new_value) {
if(strlen($new_value[attribute]) == 0){
$value = $new_value[conditions];
return $this->get_value_recursively($value);
}else{
$resultSet = array();
if (count($value) > 1){
for ($i=0;$i<count($value);$i++) {
$resultSet[] = array('attribute' => $value[$i][attribute], 'value' => $value[$i][value]);
}
$result = $resultSet;
}else{
$result = array('attribute' => $new_value[attribute], 'value' => $new_value[value]);
}
return json_encode($result, JSON_FORCE_OBJECT);
}
}
}
according to #seanbreeden answer you can call this function from first foreach
It will return the result like this :
{"0":{"attribute":"category_ids","value":"5, 15"},"1":{"attribute":"sku","value":"msj000, msj001, msj002"}}
P.S. I am not PHP dev. So, Ignore layman style code. :)
