# ActiveAdminDatetimepicker

Adds XDSoft's DateTime picker as a `date_time_picker` input for forms, and `date_time_range` for filters.

## Installation

Add this line to your application's `Gemfile`:

```ruby
gem 'active_admin_datetimepicker'
```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install active_admin_datetimepicker

Add the following line into `app/assets/stylesheets/active_admin.css.scss`:

```css
@import "active_admin_datetimepicker";
```

Add the following line into `app/assets/javascripts/active_admin.js`:

```javascript
//= require active_admin_datetimepicker
```


## Usage

This plugin adds the `date_time_picker` input and `date_time_range` filter, which use the [XDSoft DateTime Picker gem](https://github.com/shekibobo/xdan-datetimepicker-rails).

The `date_time_picker` input accepts many of the options available to the standard jQueryUI Datepicker. For example:

```ruby
  # Index page filters
  filter :created_at, as: :date_time_range

  # New/Edit form
  form do |f|
    f.input :starts_at, as: :date_time_picker, datepicker_options: { min_date: "2013-10-8",        max_date: "+3D" }
    f.input :ends_at,   as: :date_time_picker, datepicker_options: { min_date: 3.days.ago.to_date, max_date: "+1W +5D" }
  end
```

## Override behaviour in initializer

```ruby
# This if for the front-end JavaScript side
ActiveAdminDatetimepicker::Base.default_datetime_picker_options = {
    defaultDate: proc { Time.current.strftime("%Y-%m-%d 00:00") }
}
# This if for the Ruby backend
ActiveAdminDatetimepicker::Base.format = "%Y-%m-%d %H:%M:%S"
```

## Change datetime format

If you want to change the format you need to make sure that front-end and back-end formats are identical.
And remember JS and Ruby datetime format have different syntaxes.

Create configuration file `config/initializers/init_datetimepicker.rb`:

```ruby
# Example "11/03/2016 13:00"
ActiveAdminDatetimepicker::Base.default_datetime_picker_options = {
    format: 'd/m/Y H:i', # JS format
    defaultTime: proc { Time.current.strftime('%H:00') } # not necessary
}
ActiveAdminDatetimepicker::Base.format = "%d/%m/%Y %H:%M" # Ruby format
```
