【问题描述】:
已阅读有关此问题的许多问题/答案,但似乎没有找到我的解决方法。
这是问题所在:我正在按照 Rails 的入门指南创建一个简单的注解寄存器。我的表单工作 - 可以添加新的和更新注释。然而,当我向索引添加链接时,出现路由错误:
- 这:
<%= button_to "Details", annotation_path(annotation), :class => "btn btn-primary btn-xs"%>导致:没有路由匹配 [POST] "/annotations/5" - 这个:
<%= button_to "Add Annotation", new_annotation_path, :class => "btn btn-primary btn-xs"%>到 没有路由匹配 [POST] "/annotations/new"
感谢您的帮助
Routes.db:
Rails.application.routes.draw do
root 'dashboard#index'
devise_for :users
resources :users, :annotations
控制器:
class AnnotationsController < ApplicationController
def index
@annotations = Annotation.all
end
def show
@annotation = Annotation.find(params[:id])
end
def new
@annotation = Annotation.new
end
def edit
@annotation = Annotation.find(params[:id])
end
def create
@annotation = Annotation.new(annotation_params)
@annotation.save
redirect_to @annotation
end
def update
@annotation = Annotation.find(params[:id])
if @annotation.update(annotation_params)
redirect_to @annotation
else
render 'edit'
end
end
def destroy
@annotation = Annotation.find(params[:id])
@annotation.destroy
redirect_to annotations_path
end
private
def annotation_params
params.require(:annotation).permit(:name, :description)
end
end
还有形式(=部分)
<%= simple_form_for @annotation, url: annotations_path, html: { class: 'form-horizontal' },
wrapper: :horizontal_form,
wrapper_mappings: {
check_boxes: :horizontal_radio_and_checkboxes,
radio_buttons: :horizontal_radio_and_checkboxes,
file: :horizontal_file_input,
boolean: :horizontal_boolean
} do |f| %>
<%= f.error_notification %>
<%= f.input :name, placeholder: 'Enter name' %>
<%= f.input :description, placeholder: 'Description' %>
<%= f.input :file, as: :file %>
<%= f.input :active, as: :boolean %>
<%= f.input :choice, as: :check_boxes,
collection: [
'Option one ...',
'Option two ...'] %>
<%= f.input :documenttype, as: :radio_buttons,
collection: ['Type1', 'Type2'] %>
<%= f.button :submit %>
<% end %>
表格注意:无济于事,我尝试使用<%= simple_form_for :annotation, url: annotations_path,
【问题讨论】:
-
添加
method: :get。button_to默认情况下会执行POST请求,而您的这些路由是GET -
另外,我坚持要仔细调查错误日志。问题本身说“POST”路由不匹配,这意味着该路由不存在,您可以检查为什么会这样。
