How to define a Doctrine mappedSuperclass using XML or YAML instead of annotation mapping

阅读更多关于 How to define a Doctrine mappedSuperclass using XML or YAML instead of annotation mapping

问题 The following script comes from https://www.doctrine-project.org/projects/doctrine-orm/en/2.6/reference/inheritance-mapping.html#mapped-superclasses, and was only changed to include a second sub-class. It is my understanding that MappedSuperclassBase cannot exist by itself but must be extended by one and only one sub-class (i.e. either EntitySubClassOne or EntitySubClassTwo ), and is the same concept as supertype/subtype for SQL. Agree? How is a super/sub type defined using either YAML or XML

Table Inheritance with Doctrine

阅读更多关于 Table Inheritance with Doctrine

NTRODUCTION Lately we had several projects where we had to store in a database very different items that shared a common state. As an example take the RocketLab website you are reading: Events and BlogPosts are aggregated in the LabLog list as if they were similar items. And indeed they all have a Title, a Date and a Description. But if you get the detail page of an Event or a BlogPost you can see that they actually don’t contain the same information: a BlogPost contains essentially formatted text when an Event contains more structured information such as the place where the event will take

Using Redis for Doctrine Caching in Symfony2

阅读更多关于 Using Redis for Doctrine Caching in Symfony2

Redis is an open source key-value cache and storage, which designed to be very fast since it uses in-memory datasets. Of course, you can persist your data by dumping it to the disk if you need it. Redis supports different data structures such as strings, lists, sets/sorted sets, hashes; atomic operations on these types, master-slave asynchronous replication, transactions, etc. If you are using Doctrine with Symfony, Redis is a great tool to be used for caching, which is very easy to setup and it can drastically improve performance of your application. Doctrine supports 3 types of caching :

Best way to store chat messages and files

阅读更多关于 Best way to store chat messages and files

问题 I would like to know what do you think about storing chat messages in a database? I need to be able to bind other stuff to them (like files, or contacts) and using a database is the best way I see for now. The same question comes for files, because they can be bound to chat messages, I have to store them in the database too.. With thousands of messages and files I wonder about performance drops and database size. What do you think considering I'm using PHP with MySQL/Doctrine? 回答1: I think
