Certificate button "download" doesn't appear on student dashboard

[Saikou Balde]

Hello guys,

I have a Cypress Fullstack installed on Ubuntu 14

While I generate a certificate for a single user, the "download certificate" button doesn't appear onto the dashboard. See the attached screeshot.

I use the following command to generate to certificate for a single user.

"./manage.py lms --settings aws regenerate_user -u ho...@example.com -c course-v1:edX+DemoX+Demo_Course --insecure"

Here is what I see inside the "edx.log"

template = lookup_template(namespace, template_name)

And when use the generate certificate report command I have the following lines wich show that the lcertificate has been generated and is downloadable.

Is there anyone that has alreday faced the same error?

Looks like a permissions issue: [Errno 13] Permission denied: '/tmp/mako_lms/35b4de82addd2666f931e3dcd3a9da25/chemicalequationinput.html.py’ Does your user account on the fullstack instance have permission to access that file?

Also, edX does not support running Open edX on Ubuntu 14.04. We recommend using Ubuntu 12.04.

The regenerate_user management command must be run as user www-data on the full stack.  See

    https://github.com/edx/configuration/wiki/edX-Managing-the-Full-Stack#generate-certificates-after-a-course-ends

for further details.

Hello Sven,

I ran it as "www-data” and able to generate the certificate.

I can see the certificate when i copy paste the download link from the database table “certificate_generatedcertificate” to my browser.

Unfortunately, I still don’t have the “download” button on my dashboard.

I recompiled the assets and restarted the edxapp but it doesn’t change anything.

Regards,

Saikou

We are facing the same issue.

Is it resolved? If so, Can you help us on this?

Looking forward.

Thanks.

[Sivakumar]

Initially, I ran the following command to generate the certificate,

sudo -u www-data /edx/bin/python.edxapp ./manage.py lms --settings aws ungenerated_certs -c course-v1:XXXX+SA101+2016_T1

At that time, I was able to download the certificate from the dashboard.

After some time, I ran the same command, after that I was not able to see download option in Dashboard and status remains "Your Certificate is Generating"

In certs-stdout.log file, I see following one,

2016-03-21 15:47:39,303 CRITICAL 30980 [certificates.gen_cert] gen_cert.py:263 - I/O error (2): No such file or directory opening /edx/app/certs/certificates/template_data/v1-cert-templates/certificate-template-XXXX-SA101.pdf

Initially, above issue did not pop up. After the running certificate generation command again, issue appeared. I don't know how to resolve this.

Can someone help me to resolve this.?

Looking forward.

Thanks.

[Sivakumar]

Hi,

Does anyone have an answer to this?

Looking Forward.

Thanks.

[Stuart O'Day]

Does the pdf file exist in the /edx/app/certs/certificates/template_data/v1-cert-templates/ directory?  Is it owned by 'certs' and world readable (-rw-r--r-- permissions when performing ls -l)?

Is your lms running on http or https?  If http need to add the option --insecure to the command line.

[Sivakumar]

There is no pdf file for the course which i have created in /edx/app/certs/certificates/template_data/v1-cert-templates/ directory. I can see the pdf file for DemoX course.

What am I missing here? What should I do to generate the pdf file?

Thanks.

[Sivakumar]

Hi,

Any Update on this?

Thanks.

[ees...@u.uchile.cl]

Hi,

You need to have a pdf to your course (try to copy the demoX course for test)

[Sivakumar]

Thanks for your prompt response.

If I copy the file, it is working perfectly.

Should I do this every time before issuing certificates (or) is there any way to automate it?

Regards,

Sivakumar.

[ees...@u.uchile.cl]

Yes, you have to do every time.  I do not if there is a automatic way.

[Sivakumar]

This is not a feasible solution.

There should be an automated way to do this.

Does someone have an idea where I am going wrong?

Looking forward.

Thanks.

Hello guys,

I have the same problem in Hawthorn, was any solution found to this?

Thanks.
