未定义的方法`images_path”错误轨道
问题描述:
我得到了一个错误,我不知道它从何而来,这是我的代码images_controller.rb未定义的方法`images_path”错误轨道
class ImagesController < ApplicationController
layout 'home2'
#before_action :set_image, only: [:show, :edit, :update, :destroy]
def crea
@image = Image.new
end
def post
@image = Image.new(params[:images])
end
end
post.html.erb
<h2 align="center">Post your own creation right here !</h2>
<br>
<div align="center">
<%= link_to 'Back', '/showcase', :class => "buttonShow" %>
</div>
<%= simple_form_for @image do |f| %>
<%= f.input :title, :required => true %>
<%= f.input :description, :required => true %>
<%= f.input :nickname, :required => true %>
<%= f.button :submit, "Post !", :class => "buttonShow" %>
<% end %>
的routes.rb
Rails.application.routes.draw do
resources "images", only: [:crea, :post]
resources "contacts", only: [:new, :create]
get 'contacts/contact'
get 'images/crea'
get 'images/post'
get 'auth/auth'
root "auth#auth"
#get 'contact' => 'contacts#contact'
get 'showcase' => 'images#crea'
get 'showcase/post' => 'images#post'
#resources "contacts", only: [:new, :create]

end
我总是相同的错误谁不帮我很多:
undefined method `images_path' for #<#<Class:0x007ffe6c718578>:0x007ffe6c68ab38>
Did you mean? image_alt
根据红宝石错误的代码行,那里的错误应该是是:
<%= simple_form_for @image do |f| %>
这是我的模型:
class Image < ApplicationRecord
attribute :title, :validate => true
attribute :description, :validate => /\A([\w\.%\+\-]+)@([\w\-]+\.)+([\w]{2,})\z/i
attribute :nickname, :validate => /\A([\w\.%\+\-]+)@([\w\-]+\.)+([\w]{2,})\z/i
末
ActiveRecord::Schema.define(version: 20160927210003) do
create_table "contacts", force: :cascade do |t|
t.string "name"
t.string "email"
t.string "message"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
end
create_table "images", force: :cascade do |t|
t.string "title"
t.string "description"
t.string "nickname"
t.string "image_filename"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
end
end
感谢的提前, 再见,
答
默认simple_forms
搜索images_path
与POST
方法,这意味着create
你的控制器的动作
但是你有这个
resources "images", only: [:crea, :post]
# Many other code
get 'images/crea'
你可以尝试改变resources
线
resources "images", only: [:crea, :create]
,并在控制器
class ImagesController < ApplicationController
layout 'home2'
#before_action :set_image, only: [:show, :edit, :update, :destroy]
def crea
@image = Image.new
end
def create
@image = Image.new(params[:images])
end
end
答
在你的routes.rb文件操作:
resources "images", only: [:crea, :post], path: 'images'

谢谢你们,这些解决方案引起关注,像雨果的名字再次形容了,谢谢。 现在,我必须更多地关注命名。
错误仍然存在,我真的不知道为什么它不能正常工作。 – Paul
