About

This application is an inventory management system that is built to address the needs of Diaper Banks as directly and explicitly as possible. Diaper Banks maintain inventory, receive donations and other means of intaking diapers (and related supplies), and issue Distributions to community partner organizations. Like any non-profit, they also need to perform reports on this data, and have day-to-day operational information they need as well. This application aims to serve all those needs, as well as facilitate, wherever possible the general operations of the Diaper Bank themselves (eg. through using barcode readers, scale weighing, inventory audits).

Closed Beta

There are currently 5 Diaper Banks, across America, that are working with our organization to use and provide critical feedback about the functionality of the application. We are grateful for their involvement, and value their input as key stakeholders.

Origins

This project took what we built for the Portland Diaper Bank in 2016 and turned it into a multitenant application, something that all diaper banks can use. We re-used models, code and other documentation where applicable as well as implemented new features and functionality requested by the prime stakeholder (PDXDB). We're super excited to have had Rachel Alston, the director of the Portland Diaper Bank, attending our event in 2017, providing guidance and giving us the best chance of success!

Development

Ruby Version

This app uses Ruby version 2.5.3, indicated in /.ruby-version and Gemfile, which will be auto-selected if you use a Ruby versioning manager like rvm or rbenv.

Database Configuration

This app uses PostgreSQL for all environments. You'll also need to create the dev and test databases, the app is expecting them to be named diaper_development and diaper_test, respectively. This should all be handled with rails db:setup.

Create your .env with database credentials

Be sure to create a .env file in the root of the app that includes the following lines (change to whatever is appropriate for your system):

PG_USERNAME=username
PG_PASSWORD=password

If you're getting the error PG::ConnectionBad: fe_sendauth: no password supplied, it's because you have probably not done this.

Seed the database

From the root of the app, run bundle exec rake db:seed. This will create some initial data to use while testing the app and developing new features, including setting up the default user.

Login

To login, use these default credentials:

Organization Admin
  Email: org_admin1@example.com
  Password: password

User
  Email: user_1@example.com
  Password: password

Contributing

Please feel free to contribute! While we welcome all contributions to this app, pull-requests that address outstanding Issues and have appropriate test coverage for them will be strongly prioritized. In particular, addressing issues that are tagged with the next milestone should be prioritized higher.

To contribute, do these things:

• Identify an issue you want to work on that is not currently assigned to anyone
• Assign it to yourself (so that no one else works on it while you are)
• (If not already a Contributor, fork the repo first)
• Checkout a new issue branch -- there's no absolute requirements on this, but we encourage the branch name format XXX-brief-description-of-feature where XXX is the issue number.
• Do the work -- discuss any questions on the Issues as needed (we try to be pretty good about answering questions!)
• (If you created a new model, run bundle exec annotate from the root of the app)
• Create tests to provide proof that your work fixes the Issue (if you need help with this, please reach out!)
• Commit locally, using descriptive commit messages that acknowledge, to the best of your ability, the parts of the app that are affected by the commit.
• Run the tests and make sure they run green; if they don't, fix whatever broke so that the tests pass
• Final commit if any tests had to be fixed
• Push up the branch
• Create a Pull Request - Please indicate which issue it addresses in your pull-request title.

Squashing Commits

Squashing your own commits before pushing is totally fine. Please don't squash other people's commits. (Everyone who contributes here deserves credit for their work! :) ). Also, consider the balance of "polluting the git log with commit messages" vs. "providing useful detail about the history of changes in the git log". If you have several (or many) smaller commits that all serve one purpose, and these can be squashed into a single commit whose message describes the thing, you're encouraged to squash.

There's no hard and fast rule here about this (for now), just use your best judgement.

Pull Request Merging

At that point, someone will work with you on doing a code review (typically pretty minor unless it's a very significant PR). If TravisCI gives 👍 to the PR merging, we can then merge your code in; if your feature branch was in this main repository, the branch will be deleted after the PR is merged.

Stay Scoped

Try to keep your PRs limited to one particular issue and don't make changes that are out of scope for that issue. If you notice something that needs attention but is out-of-scope, please create a new issue.

Testing

Run all the tests with:

bundle exec rails spec

This app uses RSpec, Capybara, and FactoryBot for testing. Make sure the tests run clean & green before submitting a Pull Request. If you are inexperienced in writing tests or get stuck on one, please reach out so one of us can help you. :)

The one situation where you probably don't need to write new tests is when simple re-stylings are done (ie. the page may look slightly different but the Test suite is unaffected by those changes).

In-flight Pull Requests

Sometimes we want to get a PR up there and going so that other people can review it or provide feedback, but maybe it's incomplete. This is OK, but if you do it, please tag your PR with in-progress label so that we know not to review / merge it.

Additional Notes

• The generated schema.rb file may include or omit id: :serial for create table, and null: false for t.datetime. According to Aaron, this can safely be ignored, and it is probably best to commit the schema.rb only if you have committed anything that would change the DB schema (i.e. a migration).
• If you have trouble relating to SSL libraries installing Ruby using rvm or rbenv on a Mac, you may need to add a command line option to specify the location of the SSL libraries. Assuming you are using brew, this will probably result in a command looking something like:

rvm install 2.5.3 --with-openssl-dir=`brew --prefix openssl` .

Becoming a Repo Contributor

Users that are frequent contributors and are involved in discussion (join the slack channel! :)) may be given direct Contributor access to the Repo so they can submit Pull Requests directly, instead of Forking first.
