No route matches [DELETE], и No route matches [PATCH]?

Получаю ошибки: No route matches [DELETE] при нажатии удалить и No route matches [PATCH] когда редактирую форму при нажатии сохранить
Вот код:
Контроллер /admin/Tasks

class Admin::TasksController < ApplicationController
  before_action :authenticate_user!
def edit
    @project=Project.find(params[:project_id])
    @task=Task.find(params[:id])
  end

  def update
    @project=Project.find(params[:project_id])
    @task=Task.find(params[:id])
    if(@task.update(task_params))
      redirect_to project_path(@project), success: 'Задача успешно обновлена!'
    else
      render 'edit', danger: 'Ошибка обновления'
    end
  end

  def destroy
    @project=Project.find(params[:project_id])
    @task=@project.tasks.find(params[:id])
    @task.destroy
    redirect_to project_path(@project), success: 'Задача успешно удалена!'
  end
