Hi Sandeep,

I installed the app in pythonanywhere cloud and tried to view the index.html file. it said :Requires web2py 2.15.5 or newer

Then I commented out the below two lines from db.py and tried again. But then it gave errors:

if request.global_settings.web2py_version < "2.15.5":

  raise HTTP(500, "Requires web2py 2.15.5 or newer")

Error ticket for "payumoney"

Ticket ID

I think this error getting because of version. I have tested on both versions 2.16.1 and 2.17.2 that working fine.

Here is demo

Thanks

[Arindam Dasgupta]

Hi Sandeep,

In my pythonanywhere page I can see the following version . So my version is 2.7.6 or 2.14.6 ?

Now I am getting a upgrade option here to version 2.17.2 but it is telling that is is an experimental one. So how do I upgrade it to one of your version ( 2.16.1 or 2.17.2). And also I I do, then will my existing apps be still there or I will have to reinstall them?

Sorry If I am asking too much questions. Thanks in advance. :-)

[sandeep patel]

Currently, you are using python 2.7.6 and web2py 2.14.6 version.

I have tested this app on python3.6.6 and web2py 2.16.1 and 2.17.2.

You can upgrade directly by clicking on the button(upgrade new to version 2.17.2).

But be careful first take back-up of your apps :)

Thanks/

[Arindam Dasgupta]

Hi I backed up my apps and clicked on the upgrade button. The result is that web2py version got changed to 2.17.2 but python version is still 2.7.6. Now how to upgrade to python 3.6.6 Please don't answer my question today. Because I know it is too much for today . :-)

[Arindam Dasgupta]

Hi sandeep,

At last I have figured it out myself and the python version is now 3.6.0

And after this change your payumoney app is also running. :-)

Thanks.

[Lovedie JC]

What about python 2.7 compatibility

[sandeep patel]

@Lovedie,

This app generated with python3 so if you are directly installing that app from git in your application folder then this will raise an error.

If you want to use with Python 2.7. these are the following steps.

1. Create a new app in your web2py environment.

2. Copy index, success, and failure function form git and import also required the library too.

3. Downloads index, success, and failure file from git and past your /view/default folder.

4. Change MERCHANT_KEY, Key, SALT with real ids

Now Payment Gateway will work.

Thanks

Sandeep Patel

[Arindam Dasgupta]

Hi Sandeep,

I have used your method and used the following ids :

def index():

    MERCHANT_KEY = "hKiHd2aX"

    key="hKiHd2aX"

    SALT = "byRHoBc0pq"

    PAYU_BASE_URL = "https://sandboxsecure.payu.in/_payment"

The code is working only when MERCHANT_KEY=key. But in your mail it seemed that MERCHANT_KEY and key are different things. From payumoney I got a merchant ID (like 6130012), merchant key and a salt.

The test transaction is completing (I am also getting an SMS) and it is taking me to the success page. But I am getting a ticket in the success page. And if I click the ticket I am getting a blank page. I cannot figure out what is wrong.. I have not changed any code I just put the correct IDs and the name/ email/ phone no. etc. Please help.

And yes, My website is http and not https yet.

 

BR//Arindam

 

[sandeep patel]

Yes, Arindam  MERCHANT_KEY  and Key both are the same. when you clicked on Internal error link than Admin is disabled because insecure channel message is shown in your browser because of your URL not secure.

you can test on localhost URL instead of this.

Thanks

Hi Sandeep,

The payment gateway worked after I used an "https" site. However I have some doubts :

1) I have to press the pay now button twice to get it working. What should I change so that one press is sufficient?

2) I had to modify the return statement of success function the following way because success.html is using a variable "c" which is not returned from the function leading to a error :

return dict(txnid=txnid,status=status,amount=amount,c=c)

3) There are some print statements in the success function. But where it is printing these lines..?

     print ("Thank You. Your order status is ", status)

And Thank you truly for the help you did to me. :-)

Best Regards,

Arindam

best regards,

stifan 

[Arindam Dasgupta]

Hi Stifan,

Not I did not put web2py server on windows. I am using python anywhere cloud :

Hi,

Have you had some time to look at the issue as to why I need to click two times in the Pay Now button to make the transactions?

Best Regards,

Arindam 

[sandeep patel]

@Arindas,

I have updated default.py and index.html in the git repository. Please check it.

Now transactions make in one click and Even you can change user info and pricing programmatically in a wen2py way. 

Let me know if you have any questions

Thanks

[Arindam Dasgupta]

Sandeep,

Thank you so much. I will check this and let you know the results. 

No matter how much I appreciate you it will never be sufficient!! Thanks a lot.

Regards,

Arindam

[Arindam Dasgupta]

Hi Sandeep,
I am facing a serious problem while using this app. It is automatically loging me out of the application after making the payment and reaching the success page. Due to this i am not able to use session.auth.user.id variable from the success page. Do you have a solution for this?
Thanks.Arindam.

Hi, I figured out that the problem i mentioned is due to the web2py version only. I need to downgrade it to 2.17.1 . But i dont know how. Transferring the whole app to a different pythonanywhere account is an option. But that road is blocked too as i just bought an ssl certificate for this account.

The previous version should be tagged in the git repository.  You will need to do a recursive pull/download to get the DAL files.
