TimestampState
This gem adds methods and scopes to your Rails models to easily interact with state flags that are stored as timestamp (datetime) values.
For example, if you have a published_at column in your Product model, then this gem adds things like product.published? and product.publish! that get and set the published_at value respectively.
Installation
Install the gem and add to the application's Gemfile by executing:
$ bundle add timestamp_states
If bundler is not being used to manage dependencies, install the gem by executing:
$ gem install timestamp_states
Usage
- Add
_atcolumn to your DB if it doesn't already exist. Example:bundle exec rails g migration AddPublishedAtToProducts published_at:datetime && bundle exec rails db:migrate - Add
timestamp_state :column_nameto your model. Example:timestamp_state :published_at
Model methods:
Product.first.published? # true of false
Product.first.publish # sets value to now
Product.first.publish! # sets value to now and saves
Product.first.timestamp_states # returns [:published]Scopes:
Product.published # gets all published products
Product.not_published # gets all unpublished products
Product.published_at(1.day.ago..Time.now.utc) # gets all published products within the last day
Product.published_at("2023-10-28 to 2023-11-29") # gets all published products within that date range (useful for filters with Flatpickr JS)Callbacks:
after_publish :do_something # runs the callback after the product is published (after the timestamp is set AND saved)
before_publish :do_something # runs the callback before the product is published (after the timestamp is set AND saved)Development
