django_payubiz is wrapper for payubiz payment gateway for django based web application. I can see the internet many of the developers are asking about following doubt

• Getting error while creatig hash val
• Redirection is not happening
• Transaction failure

be cool now you don't worry about the these things i have the solution for this.

Installation
* Install django_payubiz from PYPI repository or clone the package from the [django_payubiz repo](https://github.com/renjithsraj/django_payubiz.git)
    `pip install payu_biz`

Settings

Step 1 :
    * Include the `payu_biz` package in to the INSTALLED_APPS
    
        `INSTALLED_APPS = (
                'django.contrib.auth',
                'django.contrib.contenttypes',
                'django.contrib.sessions',
                'django.contrib.sites',
                'django.contrib.messages',
                'django.contrib.staticfiles',
                'home',
                'payu_biz' ## Package
            )``
    
Step 2:
    Add following parameters in the project settings.py(project/settings.py)

    Note : For the Testing purpose you don't need to include ['PAYMENT_MODE',
    'MERCHANT_KEY','MERCHANT_SALT'] in the projects.

    * PAYMENT_MODE
      * The value should be one of the items from the list ['production', 'test']
          `PAYMENT_MODE = "production" ` `default will be "test"`

    * MERCHANT_KEY
       * merchant_key from payu. default value will be included builtin in the package.
           `MERCHANT_KEY = "xxxxxxxx" `

    * MERCHANT_SALT
       * merchant_salt from payu. default value will be included builtin in the package.
          `MERCHANT_SALT = "xxxxxxxx" `

    * SUCCESS_URL
      * Where to redirect while transaction is succeeded.
          `SUCCESS_URL = "www.example.com/success/" `

    * FAILURE_URL
      * Where to redirect while transaction got failure.
          `FAILURE_URL = "www.example.com/failure/" `

    * CANCEL_URL
      * Where to redirect while transaction got canceld
          `CANCEL_URL = "www.example.com/cancel/"

         cleaned_data = {
                'txnid': "aaaaassss", 'amount': 450000, 'productinfo': "sample_produ",
