following is my code to fetch record from table
$joins=array(
array(
'table' => 'users',
'alias' => 'User',
'type' => 'LEFT',
'conditions' => array(
'User.id= Notification.UserId'
)
)
);
// fetching all records
$returnArray = $this->find('all', array(
'fields' => array('Notification.id','User.Name'),
'joins' => $joins,
'order' => 'Notification.id DESC',
'limit'=>'100',
));
In above code my limit is not working coz i am using joins. can anybody tell me how to use limit with joins in cakephp.
Is there any other method to add limit? PLease tell me ASAP
Thanks in advance
I'm not familiar with Cake, but try an integer instead of string with your limit.
$returnArray = $this->find('all', array(
'fields' => array('Notification.id','User.Name'),
'joins' => $joins,
'order' => 'Notification.id DESC',
'limit'=> 100,
));

I want to get related products based on some criteria on product attributes like, the same sku, ean and gtin codes. But my query doesn't return any results. I tried different ways to query the database but all fail. Here is my query.
$sku = $product->get_sku();
$ean = $product->get_attribute( 'EAN' );
$gtin = $product->get_attribute( 'GTIN' );
$query = new WP_Query( array(
'post_type' => array('product'),
'posts_per_page' => 20,
'post_status' => 'publish',
'meta_query' => array(
'relation' => 'OR',
array(
'key' => '_sku',
'value' => $sku,
'compare' => '='
)
),
'tax_query' => array(
array(
'taxonomy' => 'pa_ean',
'field' => 'value',
'terms' => $ean,
'operator' => '=',
),
array(
'taxonomy' => 'pa_gtin',
'field' => 'value',
'terms' => $gtin,
'operator' => '=',
)
)
) );
By the way, if a product has ean code than it doesn't have a gtin and vice versa. It always has a sku which is unique to it self. But I have it added as a check to check if query at least returns value.
I can't find good documentary on this topic and hope someone here can help.
I'm trying to get only those products which have specific brand and category.
in Product model i used this query
$products = $this->find('all', array(
'joins' => array(
array('table' => 'brands_products',
'alias' => 'BrandsProducts',
'type' => 'INNER',
'conditions' => array(
'BrandsProducts.brand_id' => $brandId,
'BrandsProducts.product_id = Product.id'
)
)
),
'group' => 'Product.id'
));
By using above query i can get only those products which has specific brand id.
Exactly i don't know how to use multiple conditions to get data from 2 HABTM tables.
in my example product HABTM relation with Category and Brands.
$products = $this->find('all', array(
'joins' => array(
array('table' => 'brands_products',
'alias' => 'BrandsProducts',
'type' => 'INNER',
'conditions' => array(
'BrandsProducts.brand_id' => $brandId,
'BrandsProducts.product_id = Product.id'
)
),
array('table' => 'categories_products',
'alias' => 'CategoriesProducts',
'type' => 'INNER',
'conditions' => array(
'CategoriesProducts.category_id' => $categoriesId,
'CategoriesProducts.product_id = Product.id'
)
)
),
'group' => 'Product.id'
));
By using this query i got error in db. SO i'm looking how to write proper query to get only those products where brand and category match.
I have a table 'activities' and the columns are grouped by three of its attributes. Now I want to fetch Activity ID that is randomly selected from all the set of groups. The query is as follows:
$act = $this->find('all', array('conditions' => $cond,
'limit' => $limit,
'fields' => array('count(*) as count, Activity.id as id'),
'page' => $page,
'group' => $group,
));
These are the things I tried and none of them worked.
1. Create a self join which should have random records
$this->bindModel(array(
'belongsTo' => array(
'Random' => array(
'className' => 'Activity',
'order' => 'rand()',
'foreignKey' => 'id',
'fields' => 'Random.id'
)
)
));
This failed because the rand() order is appended in the end which simply randomizes all fetched activities.
Added a join option
'joins' => array(
array(
'table' => 'activities',
'alias' => 'Random',
'type' => 'LEFT',
'conditions' => array(
'Activity.id = Random.id'
),
'fields' => 'Random.id',
'order' => 'rand()'
)
This also didn't work as order value is not parsed by Cake
Tried to add condition
'Activity.id >= floor(rand() * (max(Activity.id) - min(Activity.id)) - min(Activity.id))'
Gave a mysql error
Please help me out
Assuming that your query is working:
$act = $this->find('all', array('conditions' => $cond,
'limit' => $limit,
'fields' => array('count(*) as count, Activity.id as id'),
'page' => $page,
'group' => $group,
'order' => 'rand()',
'limit' => '1' // if you only want one random activity ID
));
Ok finally figured it out. We need to hack the way cake php works. In place of table name, I wrote a query to fetch randomly ordered records. Also notice the join type is 'right'. Left join wont produce randomly sorted list
$activities = $this->find('all', array('conditions' => $cond,
'page' => $page,
'limit' => $limit,
'fields' => array('count(*) as count, Random.id as id, max(Activity.modified) as Modified'),
'group' => $group,
'order' => 'Modified desc',
'joins' => array(
array(
'table' => '(select * from activities order by rand())',
'alias' => 'Random',
'type' => 'RIGHT',
'conditions' => array(
'Activity.id = Random.id'
),
)
)
));
I cant get rid of some "duplicates" in this query:
$data = $this->Collection->find('first', array(
'conditions' => array('Collection.id' => $id),
'Collection' => array(
'fields' => array(
'Collection.name'
),
),
'contain' => array(
'Product' => array(
'fields' => array(
'id'
),
'order' => 'lft ASC',
),
'Product.Detail' => array(
'fields' => array(
'product_id', // should occur only once
'image_1_zoom',
'image_1_slide',
'image_1_detail',
'image_1_thumb',
),
))));
Detail belongsTo Product and Product hasMany Detail.
My problem is, that I dont want to get more than one Detail with the same product_id.
I tried 'group' with no success. DISTINCT is not possible, since the other fields have different content and are no "real" duplicates.
Any ideas greatly appreciated! :)
Try putting 'limit'=>1 in your Product.Detail array!
my problem is very simple. I have a table named 'articles' and I'd like to get the first three recent articles order DESC. But I want also these articles be displayed if their publication date is older or equal to today. So I've had an other condition in my request. My cakephp code is the following :
$this->set('lastArticles', $this->Article->find('all', array(
'conditions' => array('Article.visible' => true),
'Article.publication_date <= ' => date('Y-m-d'),
'order' => array('Article.creation_date DESC', 'Article.id DESC'),
'limit' => 3
)));
But the problem is even if the articles with a publication date > date('Y-m-d') these ones are displayed too! Does anyone have an idea ? Thanks in advance for your answer.
Looks like your publication_date condition isn't in the conditions array. Your code should look like this:
$this->set('lastArticles', $this->Article->find('all',
array(
'conditions' => array(
'Article.visible' => true,
'Article.publication_date <= ' => date('Y-m-d')
),
'order' => array(
'Article.creation_date DESC',
'Article.id DESC'
),
'limit' => 3
)));
A bit of extra indentation and whitespace is your friend here.
See this
$conditions = array(
'Article.visible' => true,
'Article.publication_date <= ' => date('Y-m-d')
);
$order = array('Article.creation_date DESC', 'Article.id DESC');
$lastArticles = $this->Article->find('all', array(
'conditions' => $conditions,
'order' => $order,
'limit' => 3
);
$this->set('lastArticles', $lastArticles);
