rails reference a column with another name

To reference a column with another name in Ruby on Rails, follow these steps:

1. Migration:
2. Open the migration file associated with the model.
3. Locate the create_table block.
4. Use the t.column or t.column_name method to define the column with the desired name.

5. For example:

   ruby class CreateExampleTable < ActiveRecord::Migration[6.0] def change create_table :example_table do |t| t.string :original_column_name # Other columns... end end end

6. Model:

7. Open the model file associated with the table.
8. Use the alias_attribute method to create an alias for the original column name.

9. For example:

   ruby class ExampleModel < ApplicationRecord alias_attribute :new_column_name, :original_column_name # Other model code... end

10. Database Migration:

11. Run the migration to apply the changes to the database.

    bash rails db:migrate

12. Usage:

13. In your code, use the new column name (new_column_name) instead of the original one.

    ```ruby # Instead of using: ExampleModel.find_by(original_column_name: 'value')

    # Use the alias: ExampleModel.find_by(new_column_name: 'value') ```

This way, you have referenced a column with another name in Ruby on Rails.
