Question

我的form_tag搜索功能存在一些问题，我没有正确地将我重定向到可以查看搜索结果的地方。它昨天工作正常，点击搜索的提交按钮后，get控制器pets方法的search请求被触发，然后我被重定向到{{1}显示结果的页面。

问题在于，现在当我提交搜索时，它只是刷新页面（results.html.erb）并且我的参数被传递到URL但是没有显示我搜索的“宠物”。

index.html.erb

在重新定位结果页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

这是我的宠物控制器

localhost:3000/results

我的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欢迎#index：

form_tag

最后......我的 routes.rb

<form class="form-horizontal">
<%= form_tag :controller => 'pets', :action => 'search', :method => 'get' do %>
 <%= label_tag('pets[zip_code]', "Zipcode") %>
 <%= text_field_tag('pets[zip_code]') %>
 <%= label_tag('pets[species]', "Type") %>
 <%= select_tag('pets[species]', options_for_select([["Dog","Dog"],["Cat","Cat"],["Rabbit", "Rabbit"], ["Small & Furry","Smallfurry"],["Horse", "Horse"],["Pig", "Pig"],["Reptile", "Reptile"],["Bird", "Bird"],["Barnyard", "Barnyard"]])) %>
  <%= label_tag('pets[breed]', "Breed") %>
  <%= text_field_tag('pets[breed]', nil, class: 'typeahead') %>
  <%= label_tag('pets[age]', "Age") %>
  <%= select_tag('pets[age]', options_for_select([["None",""],["Baby","Baby"],["Young","Young"],["Adult", "Adult"], ["Senior","Senior"]])) %>
  <%= label_tag('pets[sex]', "Gender") %>
  <%= select_tag('pets[sex]', options_for_select([["None",""],["Male","M"],["Female","F"]])) %>
    <%= label_tag('pets[size]', "Size") %>
  <%= select_tag('pets[size]', options_for_select([["None",""],["Small","S"],["Medium","M"], ["Large", "L"], ["Xtra Large", "XL"]])) %>

 <%= submit_tag "Find Pets!" %>
 <%end%>
</form>

所以我的问题是为什么我的params传递到URL时它应该只是点击Rails.application.routes.draw do devise_for :users resources :users # resources :pets root 'welcome#index' get '/pets' => 'pets#index' post '/pets/search' => 'pets#search' resources :favorite_pets get '/my_pets' => 'users#my_pets' end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，显然，我该怎么做才能解决这个问题？

更新这是我点击“搜索”按钮时控制台的输出。

Answer 1

根据您的路线文件，搜索操作只接受POST（不是GET）：

post '/pets/search' => 'pets#search'

这似乎合适，所以只需更改表单操作即可使用POST方法：

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

Answer 2

您的路线是POST，但这没有任何意义，您是否正在尝试更新或更换宠物？不，你得到一份宠物清单。您已在表单中调用GET请求，因此您可以保留该请求并进行更改 post '/pets/search' => 'pets#search'至get '/pets/search' => 'pets#search'
