- Team, stage 3 project
- Due EOD Friday, 6 PM PST, June 19
- Submit this project with a PR
Much like other e-commerce platforms, your team will make an online store where a wide variety of products can be listed and sold by any user. This project focuses on reinforcing the major components of Rails, model validations, testing, and more complex logic such as user authentication.
- Core comprehension of:
- Routes
- Controllers
- Models
- Views
- User based application logic
- User authentication
- Testing on models and controllers
- Agile practices
- Feature branch management with Git
- Group project ownership
We will build an online platform for listing, selling, reviewing, and buying a wide variety of products listed by multiple merchants.
This platform will support different kinds of users:
- users who never log in, and primarily want to be able to browse products and mange their shopping cart
- users who become merchants by logging in, and primarily want to manage products listed in their online shop
Teams will build this online platform following these principles:
- collaborate in pairs or individually throughout the week
- report to their assigned Project Manager (one of the instructors) and have frequent communication with them
- use a task manager like Trello to track all work
- build a logical user-flow that moves across multiple controllers and models
- use HTML/CSS and Bootstap or another CSS framework to style your website
Please continue to feel free to come to the instructional team with project questions. That said, please only come to instructors with questions in pairs. Before coming to one of us, we ask that both people in the pair have looked into the issue together.
The instructors have found that when multiple people from the same team come to us and they're both looked into the question, the group has more opportunity to support each other and the questions tend to be answered more quickly because the team has thought about their question more thoroughly. It also spreads knowledge of features across the team.
- As a group decide on an app name (this may help lead the aesthetic)
- As a group decide on a team name (this will amuse your instructors)
- Have one person on your team fork/clone the project master as per usual
- Create a new rails app using
rails new . - Add all other team members as collaborators
- Each team member should clone the repo to their computer
- Create a new rails app using
- Figure out your workflow for the project, re: git and task management
- Do you want to use git branches? Pull requests?
- Review the Process Requirements below
- Determine who will be the Stand Up Leader and Task Leader for the first week
- Create a Trello board to use as a Kanban board and ensure that all team members and the PM have access
- Review the Functional Requirements below and create Trello tasks to represent them
- Slack your team name, app name, and invitation link to your Trello board to your Project Manager
- Begin work on drafting an ERD together as a team!
This project must have:
- 90% reported coverage for all controller and model classes using SimpleCov
- Deployment to Heroku
All images used must be hosted on an external service. To use an externally-hosted image, use absolute URLs to the website.
Examples of websites that will host your images:
- Imgur
- Google+ Photos
- Flickr
- TinyPic
You may use any other service besides those examples.
Heroku and Rails have very specific requirements to make images appear correctly after deployment. To avoid distracting yourselves from fighting deployment fires, we recommend using externally hosted images
We expect you to follow this modified Agile process as you work on this project:
Each team will have team leaders who are responsible for keeping track of each team member's contributions. Rotate leader roles at the beginning of the second week; every team member will be in at least one leader role during the project.
The stand up leader has the following responsibilities:
- Determine the daily time for team standup. Once a time is decided, confirm with the PM that this time will work for them
- Notify team members about meeting schedule and ensures that everyone is present and ready
- Take notes about each person's update reported during stand up
- Keep the meeting moving
The task leader has the following responsibilities:
- Leads discussion on task assignment, prioritization, and organization
- Decide if a task should be completed alone or in a pair
- Assign tasks based on...
- Individual comfort
- Desire
- Ability
Make sure they're scheduled and they happen. The ideal stand up meeting is short and it's an important way to start the day on the right page. It's also the best chance to get the team together and ask for help.
Everyone is responsible for keeping the Kanban board accurate at all times.
This means the following:
- When you pick up a task, move the task from the "To do" column to "Doing"
- When you finish a task, move the task from the "Doing" column to "Done"
- When you stop work on a task, move the task from "Doing" back to "To do"
- When a task changes in nature, update the task's name and description and any relevant labels
Do not leave the responsibility of the Kanban board to just one or two people. Stay accountable to your team and the work you are doing.
At the end of each day, your team's assigned Project Manager will review the Trello board to ensure it captures the updates that your team has made throughout the day.
In a real world work environment, a team's success is measured by their product as opposed to each individual's contribution.
Each team will present their progress and respond to questions from their Project Manager at the halfway mark of the project. Every team member will participate in these demos; the PM will ask specific questions regarding:
- The team's progress and plan for completing the project
- The technical decisions and implementation
- Every team member's understanding of the underlying technical structures
On the first Friday, instead of our normal full-class retro, each team will get together and conduct a small-scale retro. One team member should facilitate, this may be the standup leader or someone else. Your retro should focus on the following questions:
- What has gone well?
- What could have gone better?
- Where is our direction still unclear?
It is required on this project that each person follows the workflow of a full-stack developer.
Each person is not required to be an expert on each thing, or to do the work perfectly.
However, after project setup has happened and project feature development is underway, each developer will be responsible for maintaining good practices.
For each task/feature that you work on, you are also responsible for:
- writing all of the unit tests relevant to their feature (nominal and edge cases)
- writing all of the controller tests (nominal and edge cases)
- writing the view code needed for the feature
- running the tests before pushing code
- adhering to the team's standards of git hygiene (PRs, branches, etc)
Do not leave writing the tests to your features to someone else!
This project contains many user stories, some of which are more relevant to our in-class learning goals than others. Here is a rough categorization of how important various features are:
- Browsing products
- Using the shopping cart (adding items, checking out)
- Authentication as a merchant
- CRUD on products, including authorization rules
- Model testing, particularly for any custom logic
- Controller testing
- Product categories
- Basic validations (things that will break the site)
- Tracking product inventory
- Order fulfillment
- Reviews and ratings
- Comprehensive validations, particularly around submitting an order

Each team will present their product in a final presentation to the group on the final Friday. Your presentation should be no more than 7 minutes. The presentation should include every team member and:
- what you learned as individuals and as a group
- a short story-driven demo of interesting features
Your final project must be deployed to Heroku. Your team will open a single pull request for the entire project. There are comprehension questions to answer with your submission that you should complete together as a group. Remember, you can submit a PR and still make some final changes to your code, so don't wait until the last minute.
We ask you and your team members to list specific areas of feedback for instructors. Please be specific about files and lines of code. Please do not give an answer vague, like "testing"! Thank you!
Check out the feedback template which lists the items instructors will be looking for as they evaluate your project.
