Rails ActiveRecord date between

📝 Hey there, tech enthusiasts!

👋 Welcome back to another exciting blog post where we dive deep into the world of technology. Today, we have a burning question to address: how can we use Rails ActiveRecord to query comments made within a specific date range? Let's get started! 💪

🔎 In this scenario, our user needs to query comments based on the created_at field, which is a part of the standard timestamps in Rails. The selected date is coming from a date_select form input. The user wishes to find all comments made on a particular day, right down to the last second.

💡 The user already provided an example SQL query as a reference. In SQL, we could use the BETWEEN keyword with the desired date range to achieve our goal. But let's explore how we can accomplish the same task using the power of ActiveRecord, the ORM (Object-Relational Mapping) in Rails.

🔑 Solution: Using ActiveRecord to Query Comments within a Date Range

To accomplish this task with ActiveRecord, we can make use of the rich querying capabilities it offers. Here's the step-by-step process to perform the desired query:

1. Parse the date_select parameters: The first step is to take the selected date values from the date_select input and convert them into a Date object. Let's assume the selected date values are stored in the variables year, month, and day.

selected_date = Date.new(year, month, day)

1. Build the date range: Next, we need to construct a range from the beginning of the selected day to the end of the day. We can use the beginning_of_day and end_of_day methods provided by Rails ActiveSupport to achieve this.

range = selected_date.beginning_of_day..selected_date.end_of_day

1. Query the comments table: Finally, we can use the range we created to query the comments table in our database and retrieve all the comments within the specified date range using the where method.

comments = Comment.where(created_at: range)

And that's it! 🎉 We have successfully queried the comments table in ActiveRecord to find all the comments made within the selected date range.
