How do I group Laravel Eloquent results by days when timestamps vary?

Grouping Laravel Eloquent Results by Days

In Laravel, when querying a database, you may encounter the need to group results by days instead of timestamps. Here's a detailed question and answer to address this specific scenario:

Question:

I have a table named page_views, which stores records of page visits along with timestamps, user IP addresses, and page IDs. Despite using the groupBy method, queries don't correctly group data by days due to differences in seconds within the timestamps.

I desire to fetch results based on views per day, which should resemble:

  date          views
  ====          =====
10-11-2013       15
10-12 2013       45
  ...            ...

Can anyone provide insights or solutions?

Answer:

To effectively group results by days, the answer suggests leveraging MySQL's DATE() function, which extracts the date portion from a DateTime value:

DB::table('page_views')
      ->select(DB::raw('DATE(created_at) as date'), DB::raw('count(*) as views'))
      ->groupBy('date')
      ->get();

However, this raw query approach deviates from Eloquent's query builder syntax. For a more Eloquent-oriented solution, the answer presents the following:

$visitorTraffic = PageView::where('created_at', '>=', \Carbon\Carbon::now->subMonth())
                            ->groupBy('date')
                            ->orderBy('date', 'DESC')
                            ->get(array(
                                DB::raw('Date(created_at) as date'),
                                DB::raw('COUNT(*) as "views"')
                            ));

This query utilizes Carbon dates in the initial where clause for comparison and applies appropriate DB raw expressions within the get method to retrieve both the date and view count.
