Question

令人惊讶的是，我无法通过这个简单的form_tag向我发送一段时间......这对我的上一个项目起作用了。我做了它的副本，使用了不同的Ruby版本，现在它不起作用。试过很多东西，但它不起作用。

我有这个块：

<div class="row">
  <div class="col-md-8">
    <div id="light-pagination" class="pagination"></div>
  </div>
  <div class="col-md-4" style='float:right'>
    <%= form_tag("/go_to_show_question", class: "form-inline", method: "get") do %>
        <%= hidden_field_tag(:id, @question_group.id) %>
        <%= search_field_tag :question, '', size: 5, class: 'form-control' %> 
        <%= submit_tag r("tests.go_to_question"), class: 'btn btn-default' %>
    <% end %>
  </div>
</div><br>

我正在输入一个数字，然后点击“转到问题”。它只发送：

{"controller"=>"question_groups", "action"=>"go_to_show_question", "locale"=>"en"}

＆＃39; id＆＃39;和＆＃39;问题＆＃39;？他们为什么不一起被送到一起？

我相信这是一个愚蠢的东西，但我无法找到它...之前有效。我相信我没有改变它。

这是生成的HTML

<div class="row">
  <div class="col-md-8">
    <div id="light-pagination" class="pagination"></div>
  </div>
  <div class="col-md-4" style='float:right'>
    <form class="form-inline" action="/go_to_show_question" accept-charset="UTF-8" method="get"><input name="utf8" type="hidden" value="&#x2713;" />
      <input type="hidden" name="id" id="id" value="28" />
      <input type="search" name="question" id="question" value="" size="5" class="form-control" /> 
      <input type="submit" name="commit" value="Go to question" class="btn btn-default" />
    </form>          
  </div>
</div><br>

路线：

Rails.application.routes.draw do

  ... other routes ...

  scope ":locale", locale: /#{I18n.config.available_locales.join("|")}/ do

    ... other routes ...

    get 'go_to_show_question' => 'question_groups#go_to_show_question'

    ... other routes ...

  end
  get '*path', to: redirect("/#{(I18n.locale)}/%{path}"), constraints: lambda { |req| !req.path.starts_with? "/#{I18n.locale}/" }
  match '', to: redirect("/#{(I18n.locale)}"), via: [:get, :post, :put, :delete]
end

控制器：

class QuestionGroupsController < ApplicationController
  def go_to_show_question
    redirect_to show_question_group_path(:id => params[:id], :question => (params[:question].to_i - 1))
  end
end

此请求到达我的控制器。但没有身份证，问题参数。

这是Log

Processing by QuestionGroupsController#go_to_show_question as HTML

找到答案：

<%= form_tag("/en/go_to_show_question", class: "form-inline", method: "get") do %>
        <%= hidden_field_tag(:id, @question_group.id) %>
        <%= search_field_tag :question, '', size: 5, class: 'form-control' %> 
        <%= submit_tag r("tests.go_to_question"), class: 'btn btn-default' %>
    <% end %>

我只是没有在我的表单URL前面添加语言环境。即使通过我的路线工作正常，但是：locale范围解析了请求并删除了我的参数。

就像

Started GET "/go_to_show_question?utf8=%E2%9C%93&id=28&question=88&commit=Go+to+question" for 127.0.0.1 at 2017-01-07 16:41:08 +0100

解析为

Started GET "/en/go_to_show_question" for 127.0.0.1 at 2017-01-07 16:41:08 +0100
Processing by QuestionGroupsController#go_to_show_question as HTML
  Parameters: {"locale"=>"en"}

rails form_tag不再工作
