how to update model rails

To update a model in Ruby on Rails, follow these steps:

1. Identify the Model: Determine the model you want to update.

2. Retrieve the Record: Use the appropriate method (e.g., find_by or find) to retrieve the record you want to update.

3. Modify the Record: Update the attributes of the record using the appropriate assignment syntax, for example, record.attribute = new_value.

4. Save the Changes: Call the save method on the record to persist the changes to the database.

5. Handle Validation Errors: If there are validation errors, handle them appropriately to provide feedback to the user or take corrective action.

6. Verify the Update: Check that the record has been successfully updated by inspecting the database or using appropriate queries.

These steps will allow you to effectively update a model in Ruby on Rails.
