MARC21 Library Standards

Library of Congress

What is Marc record ? A Marc record is a MAchine-Readable Cataloging record

Machine-readable means that a computer, can read and interpret the data in a record. The following pages will explain why this is important and how it is made possible.

Cataloging records come in two types: 1) Bibliographic records, which contain information about a book, serial, sound recording, videorecording, etc., and 2) Authority records, which contain standardized forms for names, titles, and subjects that are used on bibliographic records and provide cross references in catalogs

Call number: The librarian uses a Dewey Decimal or Library of Congress classification schedule to select the call number for an item. The purpose of the call number is to place items on the same subject together on the same shelf in the library. Most items are sub-arranged alphabetically by author. The second part of the call number usually represents the author's name, facilitating this sub arrangement. In other words, it is a system of numbers Dewey Decimal  used to mark and arrange mostly non-fiction books

Topic 19 - Using Dropdown Helper

In some extend , we might use multidropdown for our input which generally passing array values , type , name and manymore. Heres how we do it in laravel. Starting form create widget and respective helper and then call them using Laravel expression { ! Form::classhelper !! }

Widget Layout 

<select name = {{$name}} {{ $type }} class="{!! $class !!} select2" {!! $extra !!} style="width:100%">

    @if(is_array($option))
        @foreach($option as $id => $key)
            @if(is_array($key))
                <optgroup label="{{ $id }}">
                    @foreach($key as $optid => $opt)
                        <option value="{{ $optid }}" {!! (!empty($value) && in_array($optid, $value)) ? 'selected' : '' !!}>{{ $opt }}</option>
                    @endforeach
                </optgroup>
            @else
                <option value="{{ $id }}" {!! (!empty($value) && in_array($id, $value)) ? 'selected' : '' !!}>{{ $key }}</option>
            @endif
        @endforeach
    @else
        <option value=""></option>
        @foreach($option as $option)
            <option value="{{ $option->id }}" {!! (!empty($value) && in_array($option->id, $value)) ? 'selected' : '' !!}>{{ $option->name }}</option>
        @endforeach
    @endif
</select>

Class Helper

public static function multiDropdown($name = 'dropdown', $option = array(), $value = array(), $additional = ''){
        $classmsg = "form-control";
        $additional = Forms::additional($additional, $classmsg);
        $data = array(
            'name' => $name,
            'option' => $option,
            'value' => (!empty($value) && !is_array($value)) ? array($value) : $value,
            'extra' => $additional['extra'],
            'class' => $additional['class'],
            'type' => 'multiple'
        );

        return view('widget.form_dropdown')->with($data);
    }

Form View

<div class="form-group">
    <label class="col-lg-2 control-label">Course</label>
    <div class="col-lg-10">
        {!! Form::MultiDropdown('course[]',$course,'') !!}
    </div>
  </div>

Controller 

public function store(Request $request)
    {
      $catalogue = new Catalogue;
      $purchase = date('Y-m-d', strtotime($request["date_purchase"]));
      $request["date_purchase"] = $purchase;
      // $catalogueid = $request['catalogueid'];
      //
      $request['subject'] = implode(',',$request->input('subject'));
      $request['course'] = implode(',',$request->input('course'));
      $catalogue->insert($request->except('_token'));


      \Session::flash('alert-success', 'Cataloge Successfully Added');
      return redirect(route('catalogue.index'));
    }

Accessing rules ( 3 method ) 

Method 1 - By Controller 

  public function edit($id)
    {
      $typeselection = array(
        '' => '',
        '1' => 'Book',
        '2' => 'Journal',
        '3' => 'Dissertation'
      );

     $data = array(
            'breadcrumb' => array('Library', 'Catalogue','Update'),
            'content' => 'library.catalogue.form',
            'title' => 'Update Catalogoue',
            'type_selection' => $typeselection,
            'type' => 2,
        );
      return view('layouts.template')->with($data);
    }

then ,  call by writing this :

{{$item_status[$catalogue->item_status]}}

Method 2 - By Model

  public function getStatusNameAttribute()
    {
      if ($this->item_status == '1') {
        return 'On Shelf';
      }
      else if ($this->item_status == '2') {
        return 'Lost';
      }
      else if ($this->item_status == '3') {
        return 'Damage';
      }
    }

then ,  call by writing this :

{{$catalogue->StatusName}}

Method 3 - By Repository

Topic 18 - Laravel SoftDeletes

What is soft delete?

Soft delete often use to hold value or record that user might delete and restore back when needed (involve database and crud ). Soft delete require Illuminate\Database\Eloquent\SoftDeletes and declared on a model. Here is our example that might help you:

Model View 

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;

class Catalogue extends Model
{
  /**
   * The attributes that are mass assignable.
   *
   * @var array
   */

   use softDeletes;

    protected $fillable = array('id','type','status');

    protected $dates = ['deleted_at'];

}

Controller 

  public function destroy($id)
  {
    $alumni = Alumni::findOrFail($id);
    $alumni->deleted();
  }

Soft delete will not remove permanently your record instead 'deleted_at' will tell you the timestamp of your record has been deleted and thus hide the record from showing it to the user .

Possible Ways of Naming Route

Calling by giving snake case

Route::resource('patron_profile','Setting\Library\PatronProfileController');

route('patron_profile.index');

Calling by giving an alias

Route::resource('profile','Setting\Library\PatronProfileController',[

          'as' => 'patron'

        ]);

route('patron.profile.index');

Laravel Query Log - Check Query & Array Pass

Enable Query Log

Laravel can optionally log in memory all queries that have been run for the current request. Be aware that in some cases, such as when inserting a large number of rows, this can cause the application to use excess memory. To enable the log, you may use the enableQueryLog( ) method:

\DB::enableQueryLog();
        Alumni::with('alumni_careers')->findOrFail($id);
        $result = \DB::getQueryLog();
        dump($result);

With the code above , we can check wether the alumni table has relationship with alumni_careers table as define in model class. The output will be like below :

Laravel - Change Date Format

Change Date Time Format (Laravel 5.3 Above)

Below shows how the the default time picker were change into date time format that can be safe into database . This also could be use to display user date into view page.

public function update(Request $request, $id)
{
  $alumni = Alumni::find($id); //retrieve fields from model class
  date('Y-m-d', strtotime($request["dob"])); //change date format to save in database
  $alumni->update($request->except('_token')); //return all request inputs

  \Session::flash('alert-success', 'Profile Successfully Updated'); //session flash
  return redirect(route('profile.index')); //redirect
}

Topic 17 - Laravel Repository

Introduction

Just to remember laravel repository is not mandatory for laravel projects but represent as collection of specific type of entities where we write those functions and information on interface and then implement them on repositories to provide a cleaner way and easy to read for our controllers and can be used repetitively (over and over) .


Repositories interface --------------- belongs to -----> domain layer
Implementation repositories ------- belongs to ------> application-service layer

Domain Layer 

The domain model layer contains information and functionality related to what it means to be a User. It should map conceptually onto something that exists physically in the real world or a clearly defined concept in the problem space.

Service Layer

The service contains information and functionality related to performing atomic units of work. It should map conceptually onto tasks that are performed on or by members of the Domain model. A single atomic task performed by clicking a button in the application generally involves many members of the Domain working together.

Benefit of Use

1. Using repositories make our controllers less verbose , loosely coupled and easier to read.

2. Represent as concept of storage collection for specific type of entitiy (model)

3. Abstract storage mechanism for authoritative collection of entities.

4. Freedom to swap out data stores at a later date.

Without Repository 

class AlumniController extends Controllers{

  public function index(){
    $alumni = Alumni:all();
    return View::make('alumni.index',compact('alumni'));
  }

  public function create(){
    return View::make('alumni.create');
  }

  public function show($id){
    $alumni=Alumni::find($id);
    return View::make('alumni.show',compact('alumni'));
  }
}

With Repositories

1: Create the Repository Folder

2: Create class Interface

<?php
namespace App\Repositories\Alumni;

interface AlumniRepository
{
    public function getAll();

    public function show($id);

}

3: Create class Repository

<?php

namespace App\Repositories\Alumni;
use App\Models\Alumni;

class EloquentAlumni implements AlumniRepository
{

  private $model;

  public function __construct(Alumni $model)
  {
    $this->model = $model;
  }

  public function getAll(){
    return Alumni::all();
  }

  public function show($id){
    return Alumni::find($id);
  }

}

4: Create Backend Service Provider

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;

class BackendServiceProvider  extends ServiceProvider
{
    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {
        //
    }

    /**
     * Register any application services.
     *
     * @return void
     */
    public function register()
    {
      $this->app->bind('App\Repositories\Alumni\AlumniRepository', 'App\Repositories\Alumni\EloquentAlumni');
    }
}

5: Update Providers in Config/App.php

  'providers' => [
       .

       .
        App\Providers\BackendServiceProvider::class,

    ],

6: Update Your Controller

class AlumniController extends Controller
{  
    protected $alumni;

    public function __construct(AlumniRepository $alumni)
    {
      $this->alumni = $alumni;
    }

    public function index()
    {
      $alumni = $this->alumni->getAll(); // use function index in alumni interface & repository

      return view('layouts.template',compact('alumni'));
    }
}

Bootstrap Touchspin

Introduction

Bootstrap Touchspin is something that benefits and easy to use concept when working with value or numeric input . An example below shows how we increase / decrease user salary inside form bootstrap.

<div class="form-group">
    <label class="col-sm-2 control-label" >Salary</label>
    <div class="col-sm-10">
        <input id="demo1" type="text" value="0" class="form-control"           data-min="0" data-step="1.0" data-decimals="2" data-prefix="$" 
          style="display: block;">
    </div>
</div>

Example Script

  <script>
            $("input[name='demo1']").TouchSpin({
                min: 0,
                max: 10000,
                step: 1.0,
                decimals: 2,
                boostat: 5,
                maxboostedstep: 10,
                postfix: '$'
            });
        </script>

The use / meaning 

• value = initial value to be displayed
• data-min = minimum data that allowed 
• data-decimals = shows the number of decimals
• data-prefix = set the symbol of currency or any logical symbol

Datatable Custom Filter

Getting Started

Custom filter is very handy for developers to filtering their data to desired output hence able to provide a report based on a filtering they want. This topic will show the example on how to filter date search inside a datatable . Consistently consist of html , css and javascript accordingly.

HTML

<div class="row">
  <div class="large-6 columns">
    <label for="start">Start Date</label>
    <input id="start" type="date" /><br />
  </div>
  <div class="large-6 columns">
    <label for="end">End Date</label>
    <input id="end" type="date" /><br />
  </div>
</div>
<div class="row">
  <div class="large-12 columns">
    <button class="button radius" id="filter">Filter</button>
    <button id="clearFilter" class="button radius secondary">Clear Filter</button>
  </div>
</div>
<div class="row">
  <div class="large-12 columns">
    <table id="oTable">
      <thead>
        <tr>
          <th>Name</th>
          <th>Date</th>
        </tr>
      </thead>
    </table>
  </div>
</div>

CSS

body {
  padding: 20px;
}
td, th {
  min-width: 300px;
  text-align:left;
}

JAVASCRIPT

$(function(){
  // Basic Setup
  var $tableSel = $('#oTable');
  $tableSel.dataTable({
    'aaData': dummyData,
    'aoColumns': [
      {'mData': 'name'},
      {'mData': 'registered'}
    ],
    'sDom': '' // Hiding the datatables ui
  });
  
  $('#filter').on('click', function(e){
    e.preventDefault();
    var startDate = $('#start').val(),
        endDate = $('#end').val();
    
    filterByDate(1, startDate, endDate); // We call our filter function
    
    $tableSel.dataTable().fnDraw(); // Manually redraw the table after filtering
  });
  
  // Clear the filter. Unlike normal filters in Datatables,
  // custom filters need to be removed from the afnFiltering array.
  $('#clearFilter').on('click', function(e){
    e.preventDefault();
    $.fn.dataTableExt.afnFiltering.length = 0;
    $tableSel.dataTable().fnDraw();
  });
  
});

/* Our main filter function
 * We pass the column location, the start date, and the end date
 */
var filterByDate = function(column, startDate, endDate) {
  // Custom filter syntax requires pushing the new filter to the global filter array
  $.fn.dataTableExt.afnFiltering.push(
      function( oSettings, aData, iDataIndex ) {
       var rowDate = normalizeDate(aData[column]),
              start = normalizeDate(startDate),
              end = normalizeDate(endDate);
          
          // If our date from the row is between the start and end
          if (start <= rowDate && rowDate <= end) {
            return true;
          } else if (rowDate >= start && end === '' && start !== ''){
            return true;
          } else if (rowDate <= end && start === '' && end !== ''){
            return true;
          } else {
            return false;
          }
        }
  );
 };

// converts date strings to a Date object, then normalized into a YYYYMMMDD format (ex: 20131220). Makes comparing dates easier. ex: 20131220 > 20121220
var normalizeDate = function(dateString) {
  var date = new Date(dateString);
  var normalized = date.getFullYear() + '' + (("0" + (date.getMonth() + 1)).slice(-2)) + '' + ("0" + date.getDate()).slice(-2);
  return normalized;
}

// Filler data for demo (thanks to http://json-generator.com)
var dummyData = [
    {
        "name": "Chasity Stanton",
        "registered": "1992-08-12"
    },
    {
