Cannot Load Query Data Could Not Find Condition

Using custom finder methods will let you re-use your queries and make testing easier. A good way of optimizing association loading for hasMany and belongsToMany associations is by using the subquery strategy: $query = $articles->find()->contain([ 'Comments' => [ 'strategy' => 'subquery', 'queryBuilder' Board index The team • Delete all board cookies • All times are UTC - 5 hours © Copyright Ventis Media Inc. | Powered by phpBB Sitemap | Contact | Privacy You should refer to the Lazy Loading Associations and Loading Additional Associations sections for more information. have a peek at this web-site

By default results will be buffered in memory allowing you to iterate a result set multiple times, or cache and iterate the results. In that case you should use an array passing foreignKey and queryBuilder: $query = $articles->find()->contain([ 'Authors' => [ 'foreignKey' => false, 'queryBuilder' => function ($q) { return $q->where(...); // http://www.mediamonkey.com/forum/viewtopic.php?f=6&t=39127

In addition to making serialization easy, result sets are a ‘Collection' object and support the same methods that collection objects do. Failing to select foreign key fields will cause associated data to not be present in the final result. You may also want to use the get() method if you are loading entities by primary key. If you need work with a data set that does not fit into memory you can disable buffering on the query to stream results: $query->bufferResults(false); Turning buffering off has a few

Eager Loading Associations¶ By default CakePHP does not load any associated data when using find(). If the query has not been executed, a LIMIT 1 clause will be applied: // In a controller or table method. $query = $articles->find('all', [ 'order' => ['Articles.created' => The next step in the map-reduce process is to consolidate the final results. For each status created in the mapper, the $reducer function will be called so you can do any extra processing.

If you both match and contain the same association, you can expect to get both the _matchingData and standard association properties in your results. If you need full control over the query that is generated, you can tell contain() to not append the foreignKey constraints to the generated query.

Like find(), get() also has caching integrated. Tip If you need to manage more advanced trees of data, consider using Tree instead. Please login or register. You could, for example, find all the authors with no published articles in the last 10 days: $query = $authorsTable ->find() ->notMatching('Articles', function ($q) { return $q->where(['Articles.created >=' => new \DateTime('-10

Modifying Results with Map/Reduce¬∂ More often than not, find operations require post-processing the data that is found in the database. Copyright © 2003–2009 PunBB. The data from the association that is ‘matched' will be available on the _matchingData property of entities. For each call to the reducer, it will receive a list of followers per user: // $friends list will look like // repeated numbers mean that the relationship existed in both

Your cache administrator is webmaster. Check This Out Converting to JSON respects hidden & virtual field settings on all entity objects within a result set. For the rest of the association types you can use every clause that the query object provides. For example, if you wanted to get the first comment of an article as an association: $articles->hasOne('FirstComment', [ 'className' => 'Comments', 'foreignKey' => 'article_id' ]); In order to correctly fetch the

Note The first() method will return null if no results are found. The system returned: (22) Invalid argument The remote host or network may be down. While this section discusses the different ways you can find and load entities, you should read the Entities section for more information on entities. Source This is extremely simple to do with the ORM in CakePHP: // In a controller or table method. $query = $articles->find(); $query->matching('Tags', function ($q) { return $q->where(['Tags.name' => 'CakePHP']); }); You

Debugging Queries and ResultSets¶ Since the ORM now returns Collections and Entities, debugging these objects can be more complicated than in previous CakePHP versions. The queries generated by eager loading can better leverage joins, allowing more efficient queries to be made.

Result set objects will lazily load rows from the underlying prepared statement.

The find method provides an easy and extensible way to find the data you are interested in: // In a controller or table method. // Find all the articles $query = The system returned: (22) Invalid argument The remote host or network may be down. While entities' getter methods can take care of most of the virtual property generation or special data formatting, sometimes you need to change the data structure in a more fundamental way. Result sets allow you to cache/serialize or JSON encode results for API results: // In a controller or table method. $results = $query->all(); // Serialized $serialized = serialize($results); // Json $json

This finder allows you to access data stored in an ‘adjacency list' style table. However, it is possible and recommended that you implement your own finder methods. Eager loading helps avoid many of the potential performance problems surrounding lazy-loading in an ORM. have a peek here This can help with testing as there are fewer methods to mock: // In a controller or table method. $query = $articles->find('all', [ 'conditions' => ['Articles.created >' => new DateTime('-10 days')],

Finder methods are the ideal way to package up commonly used queries, allowing you to abstract query details into a simple to use method. This is due to limitations in PDO. This is useful when using aggregating functions. having add a HAVING clause to your query. join define additional custom joins. order order the result set.
