Python Django - Admin Interface

Python Django - Admin Interface

Django provides a ready-to-use user interface for administrative activities. Django automatically generates admin UI based on your project models.

Starting the Admin Interface

The Admin interface depends on the django.countrib module. To have it working you need to make sure some modules are imported in the INSTALLED_APPS and MIDDLEWARE_CLASSES tuples of the myproject/settings.py file.

For INSTALLED_APPS make sure you have −

INSTALLED_APPS = (
   'django.contrib.admin',
   'django.contrib.auth',
   'django.contrib.contenttypes',
   'django.contrib.sessions',
   'django.contrib.messages',
   'django.contrib.staticfiles',
   'myapp', #created application myapp folder
)

For MIDDLEWARE_CLASSES −

MIDDLEWARE_CLASSES = [
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

Before launching your server, to access your Admin Interface, you need to initiate the database −

C:\myprojectdjango>python manage.py migrate

migrate will create necessary tables or collections depending on your db type, necessary for the admin interface to run.

Create user

C:\myprojectdjango>python manage.py createsuperuser

input username, email address and password
Superuser created succesfully

Now to start the Admin Interface, we need to make sure we have configured a URL for our admin interface. Open the myproject/url.py and you should have something like −

 
from django.conf.urls import patterns, include, url
from django.contrib import admin

from django.contrib import admin
admin.autodiscover()

urlpatterns = [
    url(r'^admin/', admin.site.urls),
]

Now just run the server.

 C:\myprojectdjango>python manage.py runserver

 And your admin interface is accessible at: http://127.0.0.1:8000/admin/

login using created username and password

Python Django - Install Create project and run

Python Django - Install Create project and run

Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design. Django makes it easier to build better web apps quickly and with less code.

You can download the latest version of Django from the link http://www.djangoproject.com/download 

Windows Installation

C:\>pip install Django==1.9.7
c:\>python -c "import django; print(django.get_version())"

Create a Project
c:\>django-admin startproject myprojectdjango

This will create a "myprojectdjango" folder with the following structure −
myprojectdjango/
   manage.py
   myproject/
      __init__.py
      settings.py
      urls.py
      wsgi.py

manage.py − This file is kind of your project local django-admin for interacting with your project via command line (start the development server, sync db...). To get a full list of command accessible via manage.py you can use the code −
__init__.py − Just for python, treat this folder as package.
settings.py − As the name indicates, your project settings.
urls.py − All links of your project and the function to call. A kind of ToC of your project.
wsgi.py − If you need to deploy your project over WSGI.

Setting Up Your Project
Your project is set up in the subfolder myproject/settings.py. Following are some important options you might need to set −

DEBUG = True

This option lets you set if your project is in debug mode or not. Debug mode lets you get more information about your project's error. Never set it to ‘True’ for a live project. However, this has to be set to ‘True’ if you want the Django light server to serve static files. Do it only in the development mode.

DATABASES = {
   'default': {
      'ENGINE': 'django.db.backends.sqlite3',
      'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
      'USER': '',
      'PASSWORD': '',
      'HOST': '',
      'PORT': '',
   }
}

Database is set in the ‘Database’ dictionary. The example above is for SQLite engine. As stated earlier, Django also supports −

MySQL (django.db.backends.mysql)
PostGreSQL (django.db.backends.postgresql_psycopg2)
Oracle (django.db.backends.oracle) and NoSQL DB
MongoDB (django_mongodb_engine)
Before setting any new engine, make sure you have the correct db driver installed.

Now that your project is created and configured make sure it's working −

c:\>myprojectdjango>python manage.py runserver

Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.

WordPress – Adding custom fields to the post

WordPress – Adding custom fields to the post

This extra custom fields data is known as meta-data. Meta data allow you to add some additional data to the post.

Edit current theme's functions.php below code 

/*
* Add the Custom Meta Box
*/

function add_custom_meta_box() {

nbsp;               }
        echo '</td></tr>';
    }
    
    echo '</table>';
    
}

// Save the custom meta data
function save_custom_meta($post_id) {

    global $custom_meta_fields;
     
    // verify nonce
    if (!wp_verify_nonce($_POST['custom_meta_box_nonce'], basename(__FILE__))) 
        return $post_id;
        
    // check autosave
    if (defined('DOING_AUTOSAVE') && DOING_AUTOSAVE)
        return $post_id;
        
    // check permissions
    if ('page' == $_POST['post_type']) {
        if (!current_user_can('edit_page', $post_id))
            return $post_id;
        } elseif (!current_user_can('edit_post', $post_id)) {
            return $post_id;
    }
     
    // loop through fields and save the data
    foreach ($custom_meta_fields as $field) {
        $old = get_post_meta($post_id, $field['id'], true);
        $new = $_POST[$field['id']];
        if ($new && $new != $old) {
            update_post_meta($post_id, $field['id'], $new);
        } elseif ('' == $new && $old) {
            delete_post_meta($post_id, $field['id'], $old);
        }
    }
}
add_action('save_post', 'save_custom_meta');

Go to the post adding page and you can see the custom meta box and custom post fields under the post content editor.

Display the Custom Field Value

Edit current theme's single.php and add this code below

<?php 
    // Get the post meta data
    $meta = get_post_meta( get_the_ID() );
    
    // Get custom meta value
    $post_author_name = $meta['custom_author_name'][0];
    $post_photo_author = $meta['custom_photo_author'][0];
?>
<p>Author: <?php echo $post_author_name; ?> </p>
<p>Photo: <img src="<?php echo $post_photo_author; ?>"/> </p>

        $paypalURL = $this->paypal_lib->paypal_url;        
        $result    = $this->paypal_lib->curlPost($paypalURL,$paypalInfo);

            //insert the transaction data into the database
            $this->product->insertTransaction($data);
        }
    }
}

Model (Product) Creation

Product model has two methods, getRows() and insertTransaction(). getRows()

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Product extends CI_Model{
    //get and return product rows
    public function getRows($id = ''){
        $this->db->select('id,name,image,price');
        $this->db->from('products');
        if($id){
            $this->db->where('id',$id);
            $query = $this->db->get();
            $result = $query->row_array();
        }else{
            $this->db->order_by('name','asc');
            $query = $this->db->get();
            $result = $query->result_array();
        }
        return !empty($result)?$result:false;
    }
    //insert transaction data
    public function insertTransaction($data = array()){
        $insert = $this->db->insert('payments',$data);
        return $insert?true:false;
    }
}

View Creation

Into the views directory, we’ll create two folders called products and paypal. products/ holds the view file of the Products controller and paypal/ holds the view files of Paypal controller.

products:
This directory has only one view file (index.php). This file holds the HTML for all the products listing.

<div class="row">
    <?php if(!empty($products)): foreach($products as $product): ?>
    <div class="thumbnail">
        <img src="<?php echo base_url().'assets/images/'.$product['image']; ?>" alt="">
        <div class="caption">
            <h4 class="pull-right">$<?php echo $product['price']; ?> USD</h4>
            <h4><a href="javascript:void(0);"><?php echo $product['name']; ?></a></h4>
        </div>
        <a href="<?php echo base_url().'products/buy/'.$product['id']; ?>"><img src="<?php echo base_url(); ?>assets/images/x-click-but01.gif" style="width: 70px;"></a>
    </div>
    <?php endforeach; endif; ?>
</div>

paypal:
This directory has two view file, success.php and cancel.php.
The success.php file holds the HTML for displaying the transaction success notification.

<div>
    <h2>Dear Member</h2>
    <span>Your payment was successful, thank you for purchase.</span><br/>
    <span>Item Number : 
        <strong><?php echo $item_number; ?></strong>
    </span><br/>
    <span>TXN ID : 
        <strong><?php echo $txn_id; ?></strong>
    </span><br/>
    <span>Amount Paid : 
        <strong>$<?php echo $payment_amt.' '.$currency_code; ?></strong>
    </span><br/>
    <span>Payment Status : 
        <strong><?php echo $status; ?></strong>
    </span><br/>
</div>

The cancel.php file holds the HTML for displaying the transaction cancel notification.

<div>
    <h3>Dear Member</h3>
    <p>We are sorry! Your last transaction was cancelled.</p>
</div>

paypal_lib.php file will be placed in the application/libraries/ directory and paypallib_config.php file will be placed in the application/config/ directory.
