📝 Blog Post: What is the right way to override a setter method in Ruby on Rails?

Are you a Ruby on Rails developer looking for the right way to override a setter method? Look no further! In this blog post, we'll discuss the common issues, easy solutions, and provide you with the proper way to override a setter method in Ruby on Rails. Let's dive right in!

🔍 Understanding the Problem

To better understand the problem, let's take a look at the code snippet provided by the user:

attr_accessible :attribute_name

def attribute_name=(value)
  ... # Some custom operation.

  self[:attribute_name] = value
end

The above code seems to work as expected. However, the user wants to ensure if this is the right way to override a setter method and if any future problems might arise. Great question!

🐛 Potential Issues

By using the code snippet above, you may encounter the following potential issues:

1️⃣ SystemStackError: If you attempt to use self.attribute_name = value instead of self[:attribute_name] = value, you might face a SystemStackError (stack level too deep) as mentioned in the user's note.

🛠️ The Right Way to Override a Setter Method

To override a setter method correctly, you can use the write_attribute method instead of directly assigning the value to self[:attribute_name]. Here's how you can do it:

def attribute_name=(value)
  ... # Some custom operation.

  write_attribute(:attribute_name, value)
end

By using write_attribute, you ensure that the setter method is properly overridden, and you avoid potential issues such as the SystemStackError.
