Task List

Congratulations! You're submitting your assignment!

Comprehension Questions

Question	Answer
Describe in your own words what the Model is doing in Rails	The Model is the 'business' piece of the MVC. It handles logic and data. Talks to the db.
Describe in your own words what the Controller is doing in Rails	The Controller is like the 'brain' of the app. It is the middleman between User, Views and the Model.
Describe in your own words what the View is doing in Rails	The View displays data to the User that a method has collected. Every method in the controller has a matching html.erb file.
Describe an edge-case controller test you wrote	I wrote nominal cases.
What is the purpose of using strong params? (i.e. the params method in the controller)	Strong params are a security feature. We use them to give permission for which form-data is allowed in our Models.
How are Rails migrations related to Rails models?	Migrations manipulate the db schema (similar to version control for the db) and Models manipulate table data.
Describe one area of Rails that are still unclear on	I'm a day and a half behind on lectures/videos. Partial views are not clear nor is the refactoring. (yet)

Overall Feedback

Overall Feedback	Criteria	yes/no
Green (Meets/Exceeds Standards)	5+ in Code Review && 5+ in Functional Requirements
Yellow (Approaches Standards)	3+ in Code Review && 4+ in Functional Requirements, or the instructor judges that this project needs special attention
Red (Not at Standard)	0-2 in Code Review or 0-3 in Functional Reqs, or assignment is breaking/doesn’t run with less than 5 minutes of debugging, or the instructor judges that this project needs special attention	✔️ See my notes -- namely I have concerns about your project setup

Additional Feedback

Hi Charlotte! Great work on your Task List! (I like the name of it a lot)

Overall, your Rails code looks good, and you definitely have a functional Task List! Great work on accomplishing all of those features!!

These are the main comments I have:

I'm leaving a few comments and suggestions on your code on how to improve it and keep it more Rails-y!
There are a few things missing that I look forward to getting to see you practice in a future project:
- Seeing tests on those edge cases on update, all cases on destroy, and all cases on custom actions (like mark complete) (I know this was optional!)
- Styling!
- Usability improvements for the overall site-- your flow for the "home" route is confusing, and I was lost in your project! You'll see this in your comments, but also I can't see the tasks unless I use the Rails console! Similarly, it's completely hidden from the user if a task is completed or not, unless they know that they should be looking for a blank or filled in task completion date. Details like this help your product be more usable. :)
- refactoring to use strong params and resources with routes!
The biggest thing: I suspect that your project is using SQLite as a database, when we are hoping to set up our projects to use postgresql as a database. I think that you're using a different database because I see different database logs/files compared to what I'm expecting. We setup the postgresql database in the Rails template lesson. It feels important to make sure you're on the right database, so take a second to see what your Rails template looks like, and feel free to ask a classmate or me or the instructors for any help.

Let me know what else we can talk about or ask about!

app/controllers/tasks_controller.rb

+    @today = Date.today
+    @task = Task.find_by(id:params[:id])
+    @task.completed_at = @today


Since today is a variable that only matters in this action, you can leave off the @ and leave it as the local variable today! (You would make it an instance variable @today if you specifically wanted to share it with the view. However, the view that you redirect to at the end of this method doesn't need an @today instance variable shared with it!)

You may even consider just refactoring it to @task.completed_at = Date.today

tildeee · 2020-05-08T22:42:54Z

app/controllers/tasks_controller.rb

+
+  def mark_complete
+    @today = Date.today
+    @task = Task.find_by(id:params[:id])


What happens if there is no Task found? :)

tildeee · 2020-05-08T22:43:05Z

app/controllers/tasks_controller.rb

+    @task = Task.find_by(id:params[:id])
+    @task.completed_at = @today
+    @task.save
+    redirect_to task_path


Subtleties in variables: task_path is the named path that goes to the show page for one given task. tasks_path is the named path that goes to the index page for all tasks. task_path normally takes in a task as a parameter, so it'll be more clear to say redirect_to task_path(@task) or redirect_to task_path(@task.id)

tildeee · 2020-05-08T22:43:19Z

app/controllers/tasks_controller.rb

+    @task =  Task.find_by(id:id)
+
+    if @task.nil?
+      redirect_to '/tasks'


Here, you are redirecting directly to a url '/tasks'. In the small chance that this would change, it'll be better to use named paths. In this case, you'd use the named path tasks_path (much like what you did in the update method)!

tildeee · 2020-05-08T22:43:37Z

app/views/tasks/index.html.erb

+<h1>All Tasks</h1>
+<h3>Click on a Task name to view the details:</h3>
+
+<% if @tasks.length > 0 %>


Your section to add a new task is within this conditional if @tasks.length > 0. That means you can't add any tasks if there are no tasks existing!

tildeee · 2020-05-08T22:43:54Z

config/routes.rb

+  # see https://guides.rubyonrails.org/routing.html
+
+  # verb 'path' to: 'name of controller#action'
+  get '/', to: 'tasks#home', as: 'root'


It might be good to let yourself re-think and simplify your approach to the root path. Here, you declare the rootpath to go to the home action, which is an empty action, has an empty view, and doesn't have tests! It might be interesting for some projects to have a home action or root path of simply another action.

tildeee · 2020-05-08T22:44:33Z

test/controllers/tasks_controller_test.rb

+
      # Act
-      get task_path(task.id)
+      get tasks_path(task.id)


This shouldn't be altered-- the correct request for the show page is a GET to task_path

tildeee · 2020-05-08T22:44:56Z

test/controllers/tasks_controller_test.rb

  let (:task) {
    Task.create name: "sample task", description: "this is an example for a test",
-    completed_at: Time.now + 5.days
+    completed_at: "sample day/time for testing"


Out of curiosity, why did you change this?
