Question

我使用Rails 5.1和＆＃34; redirect_to @ search＆＃34;内部创造行动不起作用。

我的搜索控制器：

class SearchesController < ApplicationController
  def new
    @search = Search.new
  end

  def create
    @search = Search.create!(search_params)
    redirect_to @search # search_path(@search) doesn't work either
  end

  def show
    @search = Search.find(params[:id])
  end

private

  def search_params
    params.require(:search).permit!
  end
end

点击提交按钮创建新的搜索条目后，它不会重定向到显示页面。

我的app / views / searching / new.html.erb：

<div>
  <h1>Advanced Search Form</h1>
    <%= form_with model: @search do |form| %>
      <%= form.text_field :keywords %>
      <%= form.select :ort, options_from_collection_for_select(Imagecapturing.cities, :ort, :city_name, prompt: false, include_blank: false) %>
      <%= form.submit("Suchen", :id=>"button", :class=>"Test", :name=>"submit") %>
    <% end %>
</div>

配置/ routes.rb中：

Rails.application.routes.draw do
  root 'imagecapturings#index'
  resources :searches
end

在＆＃34;由SearchesController处理#show为JS＆＃34; ＆＃34;作为JS＆＃34;问题的一部分？

如何让重定向工作，以便在点击提交按钮后重定向到show动作？

---更新

根据用户罗克韦尔的建议，我将创建动作修改为：

def create
    @search= Search.create!(search_params)
    respond_to do |format|
      if @search
        format.html {redirect_to @search}
        format.json { render :show, status: :created, location: @step }
        format.js { redirect_to @search }
      else
        format.html { render :new }
        format.json { render json: @search.errors, status: :unprocessable_entity }
        format.js { render :new }
      end
    end
  end

但它仍然处理＆＃34;作为JS＆＃34;：

Answer 1

我相信你是对的，Processing by SearchesController#show as JS是造成你错误的原因。如果您回复格式，它应该解决您的问题。我在这里添加了HTML和JSON，但是如果你知道你永远不需要它，你就不需要了，只需要js就可以了。

def create
  @search = Search.new(search_params)

  respond_to do |format|
    if @search.save
      format.html {redirect_to @search}
      format.json { render :show, status: :created, location: @step }
      format.js { redirect_to @search }
    else
      format.html { render :new }
      format.json { render json: @search.errors, status: :unprocessable_entity }
      format.js { render :new }
    end
  end
end

如果您将此作为AJAX发送，您可以指定发送的类型，但我需要查看JS代码以提供解决方案来修复它。

Answer 2

它按预期工作，您可以在日志中看到它，插入完成，然后重定向。

但问题是你问的格式。似乎创建被称为js id（也许您正在使用该格式执行ajax请求，或者您的表单具有remote：true）。然后重定向当然不是视觉上完成的。您需要在没有js格式的情况下创建创建请求，或者不要在控制器上进行重定向并创建＆＃34; create.js＆＃34;执行重定向的视图。但当然它不是最好的解决方案。

如果要进行重定向，最好的方法是更改创建请求的格式。

redirect_to内部控制器动作不起作用
