Pluck_to_hash

Overview

The pluck_to_hash method is a powerful extension of ActiveRecord that simplifies the process of retrieving multiple columns from your database. Traditional methods return an array of arrays, but this gem returns an array of hashes, making it significantly easier to work with your data, especially when rendering JSON or accessing individual fields in your views. This method is particularly useful for developers looking to streamline their data handling in Ruby on Rails applications.

With the added support for pluck_to_struct since version 0.3.0, this functionality now returns an array of structs, providing even greater flexibility for data manipulation. The gem’s performance metrics have shown impressive results, being remarkably faster than other methods like select and as_json, making it a compelling choice for those needing efficient data access.

Features

• Array of Hashes: Returns an array of hashes instead of arrays, enhancing clarity and ease of use when handling multiple columns.

• Supports pluck_to_struct: Allows retrieval of data as structs, offering a more structured approach to data management.

• Performance Boost: Benchmarks indicate that pluck_to_hash is nearly 4 times faster than select and 8 times faster than as_json, making it an efficient option for large datasets.

• Flexible Hash Type: By default, uses HashWithIndifferentAccess, but allows specification of different hash types if needed.

• Alias Support: Offers shorter alias methods like pluck_h and pluck_s, speeding up your coding and enhancing readability.

• Block Parameters: Accepts block parameters for advanced data manipulation and greater customization in how data is processed.

• Compatibility: Can be used seamlessly with Sinatra or non-Rails frameworks by utilizing a version that removes ActiveSupport dependencies.

• Open Source Contribution: Welcomes community contributions through GitHub, promoting collaboration and feature enhancements.
