database update after paypal payment

[agoulou...@gmail.com]

hello! I am trying to update my database after paypal has received  the payment from customer. The problem is that I don't really know to do it. This is what I am doing now

here is my model

class SubmitDoc(models.Model):

    Student = 'stu'

    Professional = 'Pro'

    

    Status_CHOICES = (

        (Student, 'Stu'),

        (Professional, 'Pro'),

       

    )

    

    firstName = models.CharField(max_length =100)

    lastName = models.CharField(max_length =100)

    email = models.EmailField()

    Stud_status = models.CharField(

        max_length=3,

        choices=Status_CHOICES,

        default=Student,

    )

    uploadDoc = models.FileField(upload_to='documents/%Y/%m/%d/')   

    comment = models.TextField()

    created_on = models.DateTimeField(auto_now_add=True, editable=False)

    paid = models.BooleanField(default=False)

    finished_read = models.BooleanField(default=False)

    read_by = models.CharField(max_length = 100, default="none")

This is my view function to handle the forms that are submitted

def newSubmit(request):

    save= False

    form = SubmitDocForm(request.POST, request.FILES)

    com =0

    compteur=0

    message ="bon"

    solution = ""

    counted=0

    stud = False

    amount_stu = 0.02

    amount_pro = 0.03

    

   

    if form.is_valid():

        submitDoc = SubmitDoc()

        submitDoc.firstName = form.cleaned_data['firstName'] 

        submitDoc.lastName = form.cleaned_data['lastName']

        submitDoc.email = form.cleaned_data['email']

        submitDoc.Stud_status = form.cleaned_data['Stud_status']

        submitDoc.uploadDoc = form.cleaned_data['uploadDoc'] 

#         submitDoc.like = form.cleaned_data["like"]  

        submitDoc.comment = form.cleaned_data['comment']

        submitDoc.save()

        save = True

#         data = request.FILES["uploadDoc"]

        pathy = submitDoc.uploadDoc.path

        solution= get_docx_text(pathy)

        counted = len(solution.split())

        type_of_doc =  form.cleaned_data['Stud_status']

        

        if  form.cleaned_data['Stud_status'] == "on":

            stud = True

            totals = round(counted*0.02, 2)

        else:

            stud = False

            totals = round(counted *0.03, 2)

        

    else:

        form = SubmitDocForm()

         

    return render(request, 'francais/saved.html', locals())

My problem is that I would like to update the database, the "   paid = models.BooleanField(default=False)"  field to true after the payment is received from paypal.

Here is how I redirect the user to paypal for payment:

<form action="https://www.paypal.com/cgi-bin/webscr" method="post">

<input type="hidden" name="cmd" value="_xclick">

<input type="hidden" name="business" value="francais...@gmail.com">

<input type="hidden" name="item_name" value="Proofreading">

<input type="hidden" name="currency_code" value="CAD">

<input type="hidden" name="amount" value={{totals}}>

<input type="hidden" name="custom" value="paid">

<input id="id_cancel_return" name="cancel_return" type="hidden" value="http://www.example.com/order/21/">

<input id="id_return_url" name="return" type="hidden" value="http://www.example.com/thank-you">

<input type="submit" class="w3-btn w3-white w3-border w3-border-red w3-round-large" value ="Pay with Paypal" name="submit" alt="Make payments with PayPal - it's fast, free and secure!">

</form>

 

    

Please help me to change the paid field to "True".

This code is all irrelevant. This is the important URL:

> <input id="id_return_url"

> name="return" type="hidden" value="http://www.example.com/thank-you">

 

Wouldn't name it "thank-you" either. That would be the final page, but the flow is:

 

- Submit to PayPal

- At above return_url, receive data from PayPal:

- Check for success / failure

- If success:

set paid to True, redirect to /thank-you

- else:

display error and cart

You should use Django-PayPal app. It has views for IPN and PDT, stores transaction details in DB, does TX verification and it fires of a signal when when a successful transaction comes in to your webhook. 

All you have to do is specify some URLs and settings. It'll even render that front end form for you using a Django form. It really is a bomb. 

Cheers,

Hello Michael, 

I am having the same problem. I have no problems submitting the data from my website to paypal. I am using Django 2.0.x and just need the django IPN-listener code in an easy to understand way. I want to receive data back from paypal IPN and be able to store it in my database ie customer name, product_id, transaction_date etc. 

I have read http://django-paypal.readthedocs.io but it is difficult to follow and incomplete when it comes to returning the IPN completion. 

Thanks

Marc
