Task List Rails

We are going to build the task list using our new rails knowledge. This project will enable us to keep track of and persist, add, edit and remove tasks.

Baseline

Once you've achieved this baseline, take a walk around the room and see if you can answer questions or help other teams.

This project...

• will need to be isolated into a gemset called 'TaskListRails'
  • create the necessary files for RVM to recognize a gemset
• requires you to create a Rails 4.2.2 application
  • create and run a model and migration for a Task model
  • conform to Rails conventions on naming and inflection

Wave 1

This wave is where we will introduce the view layer where we begin interacting with our application via the browser.

• Use the provided seed data to create a script that will pre-populate your database with a given set of tasks.
  • Hint: research rake db:seed
• Set up necessary controller(s) and route(s) that you will need in order to display a task from the database
• Create a root route for your application that directs users to the list of tasks
  • The list of tasks should include the name of the task and an indicator of it is complete or not.
  • Each task name in the list should link to a show action that will render a new view for the user.
    • The show view should include the complete information about the task: name, description, completion status, and completion date.
• All markup in all views should have semantic relevance.
• Add some basic styles to your task list.

Wave 2

In this wave we will add the first set of user interactivity and persistence.

• Be able to create a new task:
  • The home page should contain a link to Add a new task. This will give the user a form to fill out with the appropriate task fields.
  • After the new task is added, the site should take the user back to the home page which displays the full list of tasks. The new task that was just added should be included in the full list of tasks.
• Be able to delete an existing task:
  • Add a route and controller action whose responsibility is deleting a task (RESTful routes)
  • On the home page, add a button or link for each task that will, once clicked...
    1. Ask the user to confirm that they definitely want to delete the task.
    2. Delete the task from the database and redirect the user back to the list of remaining tasks

Wave 3

In this wave we will extend the interactivity with users, allowing them to edit existing tasks in a couple of different ways. As always, follow RESTful conventions when implementing these features.

• Add the ability for the user to mark a task complete
  • Add a button to the list of tasks on the home page that, when clicked, will mark a task complete.
  • Update the database with the task's completed date
• Add the ability for the user to edit a task's details.
  • Add an edit action that renders a form allowing the user to update all the fields of a task.
  • Submitting the form from the edit action should update the existing task; not create a new one.
    • Research: ActiveRecord's update method.
  • Link to the edit action from the task's show page.
  • DRY up your code by reusing the view code from the new functionality
    • Research: Rendering partials in Rails.

Final Wave!

In this wave, we explore creating ActiveRecord associations by creating belongs_to and has_many relationships.

• Create a model & migration for a new Person object.
  • at a minimum, a Person should have a name
• Create seed data to add at least three Person records to the database.
• Each Task in your database can be assigned to a Person, indicating that Person is responsible for completing the Task.
  • Express the relationship between Person and Task using belongs_to and has_many
  • Update your Task index and show actions to include displaying the Person's name to which the Task belongs.
  • Update your Task's new and edit actions to allow for selecting an existing Person to which the Task should be associated.
• Add a new people (the plural of Person) controller with the following routes and actions
  • index action: Show a list of all people in the database.
    • Link each Person's name to their show action.
    • The index should include a count of how many uncompleted tasks are assigned to each Person.
  • show action: show all of the Person's information
• Create a custom route and action for showing a complete list of a Person's tasks, both complete and incomplete.
  • The url of this page should look something like http://localhost:5000/people/1/tasks.
  • Link to this action from a Person's show view.
• Deploy your completed app to Heroku.
