Active Admin has been one of the most used Administration panel in the Ruby on Rails world. It’s so easy to use. Although, I must admit looking for the right resource for customization is pain.

Here is how to Add Custom Labels to Active Admin Filters

  filter :user_name, as: :string
  filter :user_email, as: :string, label: 'User Email'
  filter :logged_in_time, label: 'Logged In Date'
  filter :logged_out_time, label: 'Logged Out Date'

The filters would automatically use the column name appended by the table name if you are using an associated table’s field. The label field would allow you to add your own custom labels to filter.

There are some things that we just need to do to finish something fast. It’s inefficient but we can get back to later on. One of those examples is retrieving the fields you need from the database.

# Optimized way to get data 
SELECT first_name, last_name FROM users;
# Non-optimized way to get data
SELECT * FROM users;

In React, there some instances that we need to pass in props from one component to another and we are just too tired to do it right now. Here is a cool way.

Best way / Optimized

const { first_name, last_name, address } = this.props;
<ChildComponent
  first_name={first_name}
  last_name={last_name}
  address={address}
/>

Cool way / Non-optimized

<ChildComponent
 {...this.props}
/>

Remember that this isn’t the optimized thing to do
