ruby-on-rails - Rails 错误 "NoMethodError"- 我的第一个 ruby​​ 应用程序

Question

我对 Rails 完全陌生，所以答案可能非常简单。开始了:

我的页面产生了这个错误

NoMethodError in Tasks#new
Showing app/views/tasks/new.erb where line #3 raised:

undefined method `tasks_path' for #

Here is the view:

<% form_for(@task) do |f| %>
    <%= f.error_messages %>

    <%= f.label :description %>:
    <%= f.text_field :description %><br />

    <%= f.label :priority %>:
    <%= collection_select(:news, :priority_id, Priority.find(:all), :id, :description) %><br />

    <%= f.submit "Add Task" %>

<% end %>

Controller :

class TasksController < ApplicationController
    def index
        @all_tasks = Task.find(:all, :order => :id)
    end

    def new
        @task = Task.new
    end ...(more)

和模型:

我看不出问题，但就像我说的，到目前为止我一无所知。 谢谢!

class Task < ActiveRecord::Base
    validates_presence_of :description

    belongs_to :priority
    has_and_belongs_to_many :staff
    has_and_belongs_to_many :catagory

end

你有吗

map.resources :tasks

在你的 route ？
