Ruby on rails 参数传递到URL Ruby on Rails,ruby-on-rails,ruby,routes,params,Ruby On Rails,Ruby,Routes,Params,我的form_标签搜索功能无法正确地将我重定向到可以查看搜索结果的位置，我遇到了一些问题。昨天工作正常，单击搜索的提交按钮后，向pets控制器search方法发出get请求，然后我被重定向到显示结果的results.html.erb页面问题是，现在当我提交搜索时，它只是刷新页面（index.html.erb），我的参数被传递到URL，但没有显示我搜索的“宠物” http://localhost:3000/?utf8=%E2%9C%93&authenticity_token=iDXug

我的

form_标签

搜索功能无法正确地将我重定向到可以查看搜索结果的位置，我遇到了一些问题。昨天工作正常，单击搜索的提交按钮后，向

pets

控制器

search

方法发出

get

请求，然后我被重定向到显示结果的

results.html.erb

页面

问题是，现在当我提交搜索时，它只是刷新页面（

index.html.erb

），我的参数被传递到URL，但没有显示我搜索的“宠物”

http://localhost:3000/?utf8=%E2%9C%93&authenticity_token=iDXugIhTyjknCMpPh2P5x7voNMSQ3Y7Aa1HIZPA7xqZ9Oj4CAuVc5eJPqfE1CLwxXAsCebgPuNWqpOk381TlvQ%3D%3D&pets%5Bzip_code%5D=10019&pets%5Bspecies%5D=Cat&pets%5Bbreed%5D=&pets%5Bage%5D=&pets%5Bsex%5D=&pets%5Bsize%5D=&commit=Find+Pets%21

之前，它只是重定向我的结果页面

localhost:3000/results

这是我的宠物控制器

class PetsController < ApplicationController



  def index #index page will render search form
    @pet = Pet.new
    #send form data in params to create
  end


  def search
    @pets = Pet.where(clean_params)
    render :results
  end

  private

  def thinned_params
    params["pets"].delete_if {|k, v| v.empty?}
  end

  def clean_params
    thinned_params.permit(:species, :zip_code, :sex, :size, :breed, :age)
  end

end

最后…我的路线。rb

所以我的问题是，为什么我的参数会被传递到URL，而URL应该只点击

pets

控制器中的

search

方法，并将我重定向到显示信息的结果页面？第二个问题，很明显，我能做些什么来解决这个问题

更新这是单击“搜索”按钮时我的控制台的输出

耙路径

根据您的路由文件，搜索操作只接受POST（不接受GET）：

这似乎是合适的，因此只需将表单操作更改为使用POST方法：

form_tag :controller => 'pets', :action => 'search', :method => :post

您的路线是

POST

，但这毫无意义，您是否正在尝试更新或更换宠物？不，你有宠物的名单。您已经在表单中调用了一个

GET

请求，因此您可以保留该请求，然后进行更改

post'/pets/search'=>“pets#search”

至

get'/pets/search'=>“pets#search”

更多。

不完全是，你更多的是

获取宠物列表，而不是更新或替换宠物。你发布了一堆表单变量。除非你想在URL中使用这些垃圾，否则使用POST。不完全是这样，你应该看看它们的意思是什么“GET方法意味着检索任何信息（以实体的形式）由请求URI标识。如果请求URI指的是数据生成流程，则应将生成的数据作为响应中的实体返回，而不是流程的源文本，除非该文本恰好是流程的输出。”“POST方法用于请求源服务器接受请求中包含的实体，作为请求行中请求URI标识的资源的新从属。这篇文章的设计是为了让一个统一的方法涵盖以下功能：“看看我对注入式答案的评论。尝试了两种解决方案，仍然是同一个问题……：（没错，是的，我完全同意你的观点。约定重于配置：）为什么索引会创建一个新的宠物？索引和搜索应该是一个动作（索引），现在我看一下。请发布您发出请求时的web服务器日志输出。这些日志将告诉您服务器认为您在请求什么，以及它试图告诉浏览器什么。现在，检查更新OK命令行上的rake routes的结果如何？查看实际的路由特德。
