Which of the following best describes the 'View' component in MVC architecture?
- It handles user input and communication between Model and Controller.
- It manages the user interface and presentation logic.
- It represents the application's data and business logic.
- It stores configuration settings for the application.
In MVC architecture, the 'View' component manages the user interface and presentation logic. It is responsible for displaying data to the user and formatting it appropriately. The View should remain decoupled from the business logic to ensure code maintainability and flexibility.
What advanced technique does CodeIgniter provide for managing complex database schemas?
- Data Seeding
- Database Migrations
- Eloquent ORM
- Query Caching
CodeIgniter provides the concept of Database Migrations, allowing developers to version control database schema changes and manage complex database schemas over time. This ensures smooth database schema evolution as the application evolves.
What is the role of resource controllers in RESTful API development using CodeIgniter?
- Resource controllers are only used for authentication in RESTful APIs.
- Resource controllers are optional in CodeIgniter RESTful API development.
- Resource controllers in CodeIgniter handle the CRUD operations for a specific resource in a RESTful API.
- Resource controllers manage database connections for RESTful APIs.
Resource controllers play a crucial role in handling CRUD operations for a specific resource in a RESTful API developed using CodeIgniter. They facilitate the implementation of RESTful principles, enabling easy management of resources through standard HTTP methods like GET, POST, PUT, and DELETE.
The configuration of the log threshold in CodeIgniter is done in the ________ file.
- config.php
- database.php
- log.php
- routes.php
The configuration of the log threshold in CodeIgniter is done in the config.php file. It allows developers to set the level of errors to be logged.
To prevent direct access to a controller's method in CodeIgniter, prefix the method name with ________.
- private
- public
- secret
- underscore
To prevent direct access, prefix the method name with an underscore (_). CodeIgniter considers methods with an underscore as private, making them inaccessible via a URL. This enhances security by restricting direct access to internal methods.
In CodeIgniter, which method is recommended for sending form data to a view?
- $this->form->open()
- $this->load->form()
- $this->load->form_open()
- $this->load->helper('form')
The recommended method for sending form data to a view in CodeIgniter is by loading the form helper using $this->load->helper('form'). This helper provides functions to create form elements and handle form submissions efficiently.
To simulate a database in unit tests, CodeIgniter recommends using ________.
- FakeDatabase
- MockDatabase
- SimDatabase
- TestDatabase
CodeIgniter suggests using the CIUnitTestCase class and the DBUnitTestCaseTrait trait to simulate a database in unit tests. This helps in testing database interactions without affecting the actual database.
For a CodeIgniter API that dynamically converts database query results to XML and JSON, the most critical aspect to optimize for performance is ________.
- Caching the API responses
- Database query optimization
- Output compression
- XML and JSON parsing
In a CodeIgniter API converting database query results to XML and JSON, the most critical aspect for performance optimization is optimizing the underlying database queries. Efficient queries contribute significantly to overall API response time.
In CodeIgniter, how are complex data relationships managed in a RESTful API serving multiple related resources?
- CodeIgniter relies on raw SQL queries for managing complex data relationships.
- CodeIgniter uses middleware for managing complex data relationships in RESTful APIs.
- CodeIgniter uses the ORM (Object-Relational Mapping) feature to handle complex data relationships in RESTful APIs.
- Complex data relationships are not supported in CodeIgniter RESTful APIs.
CodeIgniter leverages its ORM feature to manage complex data relationships in RESTful APIs efficiently. The ORM simplifies database interactions, allowing developers to define and work with relationships between different resources. This enhances the maintainability and readability of the code, making it easier to handle complex data scenarios in a RESTful API context.
The ________ function in CodeIgniter's Query Builder is essential for debugging by returning the final query string.
- debug_query()
- final_query()
- get_query()
- last_query()
The correct function for retrieving the final query string in CodeIgniter's Query Builder is last_query(). It is a valuable tool for debugging, as it allows developers to inspect the actual SQL query that was generated by the Query Builder.
