Rails 错误“NoMethodError"- 我的第一个 ruby​​ 应用 [英] Rails error "NoMethodError" - My first ruby app

问题描述

我对 Rails 完全陌生，所以答案可能很简单.这是:

I am absolutely and totally new to rails, so the answer is probably very simple. Here goes:

我的页面出现此错误

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

undefined method `tasks_path' for #

这是视图:

<% 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 %>

控制器:

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

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

和模型:

我看不出有什么问题，但就像我说的，到目前为止我一无所知.谢谢！

I can't see a problem, but like I said, I'm clueless so far. Thanks!

class Task < ActiveRecord::Base
    validates_presence_of :description

    belongs_to :priority
    has_and_belongs_to_many :staff
    has_and_belongs_to_many :catagory

end

推荐答案

你有吗

map.resources :tasks
