Active Record comes with Rails as an object-relation mapper. Rails Active Record maps the class to a table, rows to the objects of that class, and columns to object attributes (data members). It provides an interface and binds tables in a relational database with the Ruby program code that creates, reads, updates, modifies, or deletes database records.

AJAX (Asynchronous Javascript and XML) retrieves the latest information about a particular web page from the server instead of refreshing that page. Rails implements AJAX through the following steps -

• Fires trigger - The user can trigger using a link or a button and modify the data in the field or form. 

• Sends the request to the web server - XMLHttpRequest, a Javascript mthod that sends the data associated with the trigger to handle actions on the webserver. The data can be the ID of a checkbox, a particular text in the entry field, or the whole form. 

• The client receives the fragment - The server-side action handler processes the data and retrieves a fragment of an HTML page to the web client.

• Rails generates the automatic client-side Javascript, which receives the HTML fragment and updates the content.

Rails Migration is a convenient tool to modify your database schema. After running the migration, Rails puts the migration timestamp into an internal table schema_migrations. Instead of managing SQL scripts, the freelance ruby-on-rails developer defines database changes in a domain-specific language. ActiveRecord tracks which migrations have already run.

The Controller in Rails is a part of its Model-View-Controller architecture, which acts as an intermediate between model and view. When the client requests particular data, the controller contacts model and checks if the requested data is present in the database or not. It then carries the data to the view which then is responsible to display the data.

Apart from this, 

• The Rails controller controls helper modules, which increase the capabilities of the view HTML template, without inserting much bulky code.
• It also manages sessions, maintaining user-interactions with the view template.

Rake in Rails is a standalone task management and automation tool that runs ruby on rails applications. Rake is used to describe dependencies,  create databases, perform tests, and run migrations. It also groups the tasks within a namespace The freelance ruby developer can also create custom tasks specifying automatic actions such as database backup, run code analysis tools, etc.

If the page requested is not found, Redirect issues an error message to the browser and tells the browser to issue a new request. While Render is used to design the content and works only when the controller is all set with the variables that need to be rendered.

Polymorphic Association is an ActiveRecord association that connects a database model to multiple other models. Take the example of a social media application where the users model can be connected with the comments model, post_likes model, and posts model.
