Mission: add buttons to change the status of a task
HOWTO:
migration - add status column to tasks
add_column :tasks, :status, :string, null: false, default: "planned"
task.rb - list available statuses
validates :status, presence: true
STATUSES = [:planned, :progress, :done]
tasks_controller.rb - add action to change status
def change_status
@task = Task.find(params[:id])
if params[:status].present? && Task::STATUSES.include?(params[:status].to_sym)
@task.update(status: params[:status])
end
redirect_to @task, notice: "Status updated to #{@task.status}"
end
routes.rb - add actionable link to change status.
resources :tasks do
member do
patch :change_status
end
end
tasks/show.html.erb
<% Task::STATUSES.each do |status| %>
<%= link_to change_status_task_path(@task, status: status), method: :patch do %>
<%= status %>
<% end %>
<% end %>
Voila, that's it!
