'db_name' is undefined\

[vrr-data]

Hi, Was trying this out pretty much unchanged on Windows 10 Pro Host with Ubuntu 20.04 Guest. Only change I made was renaming the VM and using ansible_local in the vagrant file. I am using VirtualBox provider not docker.

I get the following error during PostgeSQL database creation. The group_vars/vagrant/vars.yaml has the application name set. The db/tasks/main doesn't seem to reference the group_vars. Not sure if I am doing something wrong or if this is a bug. Please check and let me know.

What is the structure of your group_vars directory? Note that you need to name the subdirectory environment_name, so in your case I believe it should be group_vars/pavillion/vars.yml. See https://github.com/jcalazan/ansible-django-stack#configuring-your-application

Next thing to do would be to run ansible in debug mode and show the output of that here and I'd be happy to help if I can!

[vrr-data]

Thanks for your response and sorry for the long delay. I fell ill for a while but I better now. I changed the group_vars to be group_vars/pavillion/vars.yaml I still see the same error. Other than project_name and app_name I have not changed anything in vars.yml

Line 35 in main.yml is related to the check that fails above.

• name: Ensure database is created become: true become_user: postgres postgresql_db: name: "{{ db_name }}" encoding: UTF-8 lc_collate: en_US.UTF-8 lc_ctype: en_US.UTF-8 template: template0 state: present

Now figuring out how to run ansible_local in debug mode.

[vrr-data]

I added the line debugger: on_failed under line 35 above in main.yml and I get this... I just ran vagrant provision since the VM was already up.

What does your vars.yml file look like?

[vrr-data]

No change from original except to rename django_default_project to my project name on Line #5 and #6 and commenting out Lines #13 and #14 to use offical ppa and default python.

[YPCrumble]

@vrr-data are you using the latest version of this playbook? We changed the way variables are handled such that we now use the group_vars directory for variables. If you are using this version I'd be happy to try to help you debug!

@YPCrumble

I have the same problem, I just clone and try to test provision the server This is a development inventory file

This is group vars file structure look like

This is common I ran ansible-playbook -i development webservers.yml and this is an error

I dont think ansible pick up the group var from group_vars/development/vars.yml, I explored to webserver.yml file the host is set to webservers So I try to change file name to group_vars/webservers/var.yml it worked fine So I still confuse about the project structure, Or do I do something wrong? what is your expected how env and group_vars work together?

I expect that ansible should pick up group_vars from group_vars/{env}/vars and if I have multiple env I just should create inventory per environment and it should pick up the group_vars correctly? Do you have an example project that config this and work collectively so I can try to follow your this repo practice

[YPCrumble]

@prince-tanapong thank you for the detailed report! I just added #188 - would you mind trying that to see if it doesn't solve your issue? I'm surprised that the test suite passed when we first merged this in if the db_name variable doesn't get defined, but it could be some discrepancy between the development inventory and whatever inventory we're using for Molecule tests.
