How to show only scoped instances of Task model in view - ruby-on-rails

Question

I'm building a Task Manager in Rails. I used scope to get all instances of a Task model that are due today. The scope on the Task model works and is returning only Tasks due today when calling due_today on Tasks in the Rails console. But I can't seem to show these Tasks due today in the view. Do I need to add a conditional?
This is my views index.html.erb
<p id="notice"><%= notice %></p>
<h1>Team's Tasks</h1>
<table>
<thead>
<tr>
<th>Task title</th>
<th>Description</th>
<th>Date assigned</th>
<th>Due date</th>
<th>Overdue?</th>
<th>Completed?</th>
<th colspan="3"></th>
</tr>
</thead>
<tbody>
<% #tasks.each do |task| %>
<tr>
<td><%= task.title %></td>
<td><%= task.description %></td>
<td><%= task.created_at %></td>
<td><%= task.duedate %></td>
<td><%= task.overdue? %></td>
<td><%= task.completed %></td>
<td><%= link_to 'Show', task %></td>
<td><%= link_to 'Edit', edit_task_path(task) %></td>
<td><%= link_to 'Destroy', task, method: :delete, data: { confirm: 'Are you sure?' } %></td>
</tr>
<% end %>
</tbody>
</table>

<h1>Tasks due today.</h1>
<table>
<thead>
<tr>
<th>Task title</th>
<th>Description</th>
<th>Date assigned</th>
<th>Due date</th>
<th>Overdue?</th>
<th>Completed?</th>
<th colspan="3"></th>
</tr>
</thead>
<tbody>
<% #tasks.due_today.each do |task| %>
<tr>
<td><%= task.title %></td>
<td><%= task.description %></td>
<td><%= task.created_at %></td>
<td><%= task.duedate %></td>
<td><%= task.overdue? %></td>

</tr>
<% end %>
</tbody>
</table>
<br>
<p>
<%= link_to 'New Task', new_task_path %>
</p>
this is my Task model
class Task < ApplicationRecord
#use scope on Task model to mark overdue Tasks if the present date is greater than duedate.
scope :overdue, -> { where("duedate < ?", Time.now) }
#use scope on Task model to get only tasks that are due today.
scope :due_today, ->{ where("duedate >= ? AND duedate <= ?", Date.current.beginning_of_day, Date.current.end_of_day) }
end
This is the controller
class TasksController < ApplicationController
before_action :set_task, only: %i[ show edit update destroy ]
# GET /tasks or /tasks.json
# Order all tasks by ascending order
def index
#tasks = Task.all.order(duedate: :asc)
end
# GET /tasks/1 or /tasks/1.json
def show
end
# GET /tasks/new
def new
#task = Task.new
end
# GET /tasks/1/edit
def edit
end
# POST /tasks or /tasks.json
def create
#task = Task.new(task_params)
respond_to do |format|
if #task.save
format.html { redirect_to #task, notice: "Task was successfully created." }
format.json { render :show, status: :created, location: #task }
else
format.html { render :new, status: :unprocessable_entity }
format.json { render json: #task.errors, status: :unprocessable_entity }
end
end
end
# PATCH/PUT /tasks/1 or /tasks/1.json
def update
respond_to do |format|
if #task.update(task_params)
format.html { redirect_to #task, notice: "Task was successfully updated." }
format.json { render :show, status: :ok, location: #task }
else
format.html { render :edit, status: :unprocessable_entity }
format.json { render json: #task.errors, status: :unprocessable_entity }
end
end
end
# DELETE /tasks/1 or /tasks/1.json
def destroy
#task.destroy
respond_to do |format|
format.html { redirect_to tasks_url, notice: "Task was successfully destroyed." }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_task
#task = Task.find(params[:id])
end
# Only allow a list of trusted parameters through.
def task_params
params.require(:task).permit(:title, :description, :duedate, :completed)
end
end

Answer 1

I assume you have a TasksController and an index method there.
try following in the index method
def index
#tasks = Task.due_today
end
let me know if this works

Answer 2

You need to change due_date scope.. use between or date_trunc method.
where("date_trunc('day', duedate)::date = ?", Date.today)
let me know if it works

Answer 3

Got it to work. No changes to the controller. None needed. This is the code.
This is the Task model.
class Task < ApplicationRecord
#use scope on Task model to mark overdue Tasks if the present date is greater than duedate.
scope :overdue, -> { where("duedate < ?", Time.now) }
#use scope on Task model to get Tasks due today.
scope :due_today, ->{ where("duedate >= ? AND duedate <= ?", Date.current.beginning_of_day, Date.current.end_of_day) }
def overdue?
duedate < Time.now
end
def due_today?
duedate >= Date.current.beginning_of_day && duedate <= Date.current.end_of_day
end
end
This is the Task view.
