Cannot update qty after clearing magento db

f you failed to create a new product from admin and you’ll get an error message something like this SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`cataloginventory_stock_item`, CONSTRAINT `FK_CATALOGINVENTORY_STOCK_ITEM_STOCK` FOREIGN KEY (`stock_id`) REFERENCES `cataloginventory_stock` (`stock_id`) ON DELETE CASCADE ON UPDATE) You have to check whether you deleted entry from cataloginventory_stock table. If yes then please use below query to add new product. INSERT INTO cataloginventory_stock SET stock_name = ‘Default’; for product link insert into `catalog_product_link_type`(`link_type_id`,`code`) values (1,'relation'),(2,'bundle'),(3,'super'),(4,'up_sell'),(5,'cross_sell'); insert into `catalog_product_link_attribute`(`product_link_attribute_id`,`link_type_id`,`product_link_attribute_code`,`data_type`) values (1,2,'qty','decimal'),(2,1,'position','int'),(3,4,'position','int'),(4,5,'position','int'),(6,1,'qty','decimal'),(7,3,'position','int'),(8,3,'qty','decimal'); insert into `cataloginventory_stock`(`stock_id`,`stock_name`) values (1,'Default');

magento sql 常用用法

  $resource = Mage::getSingleton('core/resource');  
  $tableName_votes = $resource->getTableName('jselfless/votes');  
  $tableName_image = $resource->getTableName('jselfless/image');  
  $collection = Mage::getModel('jselfless/woman')->getCollection();  
  $collection->getSelect()->reset(Zend_Db_Select::COLUMNS);  
  $collection->getSelect()->columns(array('items_count'=>'count(main_table.id)'));  
  $collection->addFieldToFilter('main_table.year',date('Y'));  
  $collection->addFieldToFilter('image.type','main');  
  $collection->addFieldToFilter('award',array('eq'=>''));  
  $collection->getSelect()->join(array('votes' => $tableName_votes), 'main_table.id = votes.selfless_woman_id', '');  
  $collection->getSelect()->join(array('image' => $tableName_image), 'main_table.id = image.selfless_woman_id', array('image.*'));  
  $collection->getSelect()->group('main_table.id');  
  $collection->getSelect()->Order('items_count desc');  
  $collection->getSelect()->Order('votes.created_at desc');  
  $collection->getSelect()->Order('main_table.updated_at desc');  
  $collection->getSelect()->limit(10,$postData['offset']);  

Cannot find the ACL permission in the permission list

In my custom module, i have created the adminhtml.xml for it.
However  in the system > permission , i cannot find the checkbox that allows me to assign permission to the user.

After exploring the xml, i found that i was missing <title> tag between the section node and the <children> node.

For the build-in section, e.g. <report>, we can skip the <title> tag because it will load the default value that magento assign to it.( anyway you can still add it to override the default one)

However in my case, <suepreport> is a custom new tag, so i must specify the <title> tag for it!

After adding the title tag,  i finally see it in the admin permission tree! Great!

<resources>
<admin>

                    <report>
                        <children>

SQLSTATE[23000] Duplicate entry 'xxx' for key 'PRIMARY'

Problem:

When saving related product, it shows an error :

magento  SQLSTATE[23000]  Duplicate entry '959' for key 'PRIMARY'

Reason:

yes it right, the key is really duplicate in the table

after checking the related product table --- catalog_entity_product_link, the auto increment of 'link_id' is 950 but the latest record is '959', and it doesnt make sense

Solution: 

(1) increase the auto increment to 959  , SET AUTO_INCREMENT = 959

or

(2) delete the record after 950, and then save these related product again
