@husainattar There are failing tests, please push the changes to these.

Hi @sakshi1499 actually I have not much idea with TRAVIS-CI and I have somehow resolved the failure regarding pull request build but I don't know how to resolve the failure regarding CHECK COMMIT MESSAGES.

[sakshi1499]

@husainattar Actually you have 15 commits and one of them doesn't follow the Commit Guidelines so squash them and the new commit should follow the commit guideline.

[husainattar]

@sakshi1499 ohk so I should squash all the 15 commits and create a single one commit as per guidelines?

[SanketDG]

@husainattar There is an issue with the recent commit message checker, it does not allow capital letters in the subject

https://github.com/anitab-org/portal/pull/624 should fix this.

[husainattar]

Ohh Thank you @SanketDG

[SanketDG]

@husainattar Feel free to squash the commits together! That should let go of the errors.

[husainattar]

Hi @SanketDG sir I actually tried everything and also squash the commit but still it provides me check-commits error. I would be grateful if anyone can provide help in this.Thank you

[SanketDG]

@husainattar Should be fixed now! I will review this PR some time later.

[husainattar]

Thank you @SanketDG sir thank you for the help.

[husainattar]

Btw @SanketDG I have included some important additional commands for database and common related issues in documentation. I have just not included on how we can make changes during development and get reflect in running container instantly.

yes squash it and make a single commit with all changes done in description

[Rajpratik71]

Also , @husainattar to update your working branch with Upstream branch , you can do "git rebase" instead of merging it . This approach doesn't create a new commit in your branch.

@husainattar Are you working on this?
