The form parameters that are posted are: The record will be updated, and the lock_version incremented to 2.Even if you update only a small boolean flag on your record, update_attribute will generate an UPDATE statement that will include all the fields of the record, including huge BLOB and TEXT columns. And solving that problem isn't simple (at least, not that I know. I'm going to use the same scenario from my blog post yesterday.I'm not talking about the invalid record problem anymore, only the problem with an update undoing changes from another update. I added a lock_version column, so Rails will automatically do optimistic locking. Technically, Sphinx is a standalone software package provides fast and relevant full-text search functionality to client applications.
Excepted from this license are code snippets that are explicitely marked as citations from another source.The form will have two fields, a checkbox to indicate if the employee is a manager, and a field to enter a salary.Here's why simply adding a lock_version column doesn't prevent the problem. Just like above, this method does not yet change the attribute in the database.Sphinx is a full-text search engine, publicly distributed under GPL version 2. It was specially designed to integrate well with SQL databases storing the data, and to be easily accessed by scripting languages.Applications can access Sphinx search daemon (searchd) using any of the three different access methods: a) via Sphinx own implementation of My SQL network protocol (using a small SQL subset called Sphinx QL, this is recommended way), b) via native search API (Sphinx API) or c) via My SQL server with a pluggable storage engine (Sphinx SE).
