減少在軌URL長度

Question

我有這種形式：

<h1> Global data management </h1> </br> </br> 
<h2>Enter the conditions and click "find" option to search for users based on conditions. </br> Or click the "List" option to list all the data. </h2> 
</br></br></br> 
<%= form_for(:find_field, url: find_field_path , method: :get) do |f| %> 
<div class="row"> 
     <div class="span8 offset1"> 
     <div class = "row"> 
      <div class = "span4"> 
       <div class="field"> 
       <%= f.label :data_type_choice, "Data type" %> 
       <%= f.select :data_type_choice, [["all","all"],["2D","2D"],["3D","3D"],["2D3C","2D3C"],["3D3C","3D3C"]] , :name => nil%> 
       </div> 
       </br></br> 
       <h3> COMPLETED WITHIN </h3>:</br> 
       <div class="field"> 
       <%= f.label :from_date_choice , "From date " %> 
       <%= f.date_select :from_date_choice , :name => nil%> 
       </div>   
      </div> 

      <div class = "span4">  
       <div class="field"> 
       <%= f.label :basin_choice, "Basin" %> 
       <%= f.select :basin_choice, [["all","all"],["Cauvery","Cauvery"],["KG-PG","KG-PG"],["others","others"]] , :name => nil %> 
       </div>  
       </br></br> 
       <h3>&nbsp</h3> 
       <div class="field"> 
       <%= f.label :to_date_choice , "To date " %> 
       <%= f.date_select :to_date_choice , :name => nil %> 
       </div> 
      </div> 
     </div>  

       </br></br> 
       <%= f.submit " Search ", class: "btn btn-large btn-primary" %> 

     </div> 
</div> 
<% end %> 

一切完美，所有的參數都正確傳遞等，但在我嘗試顯示的結果來看，我得到一個巨大的網址一樣所以：在這個railscast 顯示：「名稱=>無」爲什麼會這樣，我怎麼能減少URL大小隻是「HTTP：//本地主機：3000 /全球

http://localhost:3000/global/data/find?utf8=%E2%9C%93&find_field%5Bdata_type_choice%5D=2D&find_field%5Bfrom_date_choice%281i%29%5D=2012&find_field%5Bfrom_date_choice%282i%29%5D=7&find_field%5Bfrom_date_choice%283i%29%5D=9&find_field%5Bbasin_choice%5D=KG-PG&find_field%5Bto_date_choice%281i%29%5D=2012&find_field%5Bto_date_choice%282i%29%5D=7&find_field%5Bto_date_choice%283i%29%5D=9&commit=++Search++ 

香港專業教育學院使用嘗試/ data/find「？

編輯：

這是fields_controller我find方法：

def find 

    @data_type_choice = params[:find_field][:data_type_choice] 
    @basin_choice = params[:find_field][:basin_choice] 
    @from_date_choice = params[:find_field][:from_date_choice] 
    @to_date_choice = params[:find_field][:to_date_choice] 

    end 

我也想展示的形式通過find.html.erb像這樣輸入的數據：

<h1><%= @data_type_choice %> dsfgdfsg</h1> 

如果我使它成爲一個post請求，erb不會被渲染！我能做什麼？

謝謝:)

Answer 1

只需將您的方法從GET更改爲POST，並相應地更改路由。

嘗試

<%= form_for(:find_field, url: find_field_path , method: :post) do |f| %> 

你的路由文件應符合的要求爲POST。
