active record

Through some nifty lexical analysis, Active Record is able to determine that the Order class will map to the ORDERS table in the database.

It does not currently include Active Record, the powerful domain model library on which Rails database model objects are built.

ActiveRecord's static findById function is an example of a method typically found in an implementation of the active record design pattern.

But I think Active Record has quite a large niche and will improve as the mappings supported by Active Record improve.

Active Record users do not always need to change model objects as the data model changes.

The framework queries two sources of metadata: the Active Record model and a custom metadata file for each model object.

Active Record forced me to build create-table SQL scripts, tying me to an individual database implementation.

Each instance of an active record class is tied to a specific row in a database.

Each active record has methods to access each column, as well as methods to save, delete, or update the row.

Active Record associates a class with a table and dynamically adds an attribute to each class for every column in the database.

Active Record generates the SQL to tell the database to insert the record.

The relational schema is the center of your Active Record universe.

The Streamlined creators could have easily added customization data to Active Record.

The streamlined directory allows additional metadata without pollution of Active Record.

By default, Rails captures enough metadata within Active Record to build a surprisingly sophisticated default user interface.

Let's take at look at a simple (and partial) implementation of the active record design pattern.

You also see nice integration between Active Record (the Rails persistence engine) and the model-view-controller (MVC) framework.

Other lightweight solutions, such as iBATIS and the Active Record design pattern, don't try to do object-relational mapping at all.

Active Record is an object-relational mapping (ORM) that follows a standard ORM model.

A cool feature often provided in active record design pattern implementations is dynamic finder methods.

You use the active record pattern to wrap relational database persistence methods in domain classes.

From the very beginning, Active Record has helped to evolve my understanding of persistence.

So, like Active Record, the RIFE framework uses convention over configuration.

There are many Active Record updates in this release including the introduction of nested transactions.

Active Record relies on language capabilities to extend Rails classes on the fly.

The Streamlined approach lets a single place consolidate common view characteristics, much as Active Record does for persistence concerns.

Active Record adds a custom finder for each of the attributes.

Next, create the classes in your app that will use the active record pattern to model a database table.

Each one reflects on metadata from Active Record and Streamlined.

So Active Record is actively managing the relationship.

Rails creates your project, and you can use Active Record through some nifty Rails tools.

This article will show examples of how to validate a model using Active Record's set of validators.

You can find a list of the Active Record model validations that can be defined in the class scope here.

The best way to show you how Active Record handles persistence is to write some code.

Rails has a somewhat magical component called the Active Record.

In the sweeper, a developer can define an active record event, such as after_save.

In fact, Active Record lets you have a number of different relationships, including these
