当我单击表单中的提交按钮时，创建操作应该有效，但它是由新操作处理的

Question

在我的应用程序中，我有一个应该由创建操作处理的表单，但它是由新操作处理的。这个问题发生在我的 post 任务表单中，但在我的其他表单（注册表）中，它工作得很好（它由创建操作处理）。所以我认为罪魁祸首可能出在我的模型关系中，所以我也会 post 在这里：

用户模型

has_many :client_relationships, class_name: "Task", foreign_key: "client_id", dependent: :destroy

has_many :worker_relationships, class_name: "Task", foreign_key: "worker_id", dependent: :destroy

has_many :worker_tasks, through: :client_relationships, source: :worker

has_many :client_tasks, through: :worker_relationships, source: :client

任务模型

belongs_to :client, class_name: "User"

belongs_to :worker, class_name: "User"

在我的routes.rb

resources :users do
  member do
   get :client_tasks, :worker_tasks
   end
  end

resources :tasks

如果您想知道，我有两个用户在执行任务 table（client_id、worker_id）。我在用户 table 中有一个布尔列来识别他们。我也有约会 table 属于任务，但我没有把它包括在这里。

现在，单击提交按钮后，我从 cmd 中获取了这个：

Processing by TasksController#new as HTML
  Parameters: {"utf8"=>"V", "authenticity_token"=>"e5K/I8TpQJwpqGtapZs7xP4n7i3FF
a9xHVSv7CLVYIsYSomK95x6B+J2hSbr77CHvxI01te8hQ7HOGRTRLANNg==", "task"=>{"category
_id"=>"", "title"=>"", "description"=>"", "pay_type"=>"", "pay_offer"=>"", "coun
ty_id"=>"", "area_id"=>"", "appointments_attributes"=>{"0"=>{"start_date"=>"", "
start_time"=>"", "end_date"=>"", "end_time"=>""}}}, "commit"=>"Create Task"}
ty_id"=>"", "area_id"=>"", "appointments_attributes"=>{"0"=>{"start_date"=>"", "
start_time"=>"", "end_date"=>"", "end_time"=>""}}}, "commit"=>"Create Task"}

我在浏览器上得到这个：

http://localhost:3000/tasks/new?utf8=%E2%9C%93&authenticity_token=e5K%2FI8TpQJwpqGtapZs7xP4n7i3FFa9xHVSv7CLVYIsYSomK95x6B%2BJ2hSbr77CHvxI01te8hQ7HOGRTRLANNg%3D%3D&task%5Bcategory_id%5D=&task%5Btitle%5D=&task%5Bdescription%5D=&task%5Bpay_type%5D=&task%5Bpay_offer%5D=&task%5Bcounty_id%5D=&task%5Barea_id%5D=&task%5Bappointments_attributes%5D%5B0%5D%5Bstart_date%5D=&task%5Bappointments_attributes%5D%5B0%5D%5Bstart_time%5D=&task%5Bappointments_attributes%5D%5B0%5D%5Bend_date%5D=&task%5Bappointments_attributes%5D%5B0%5D%5Bend_time%5D=&commit=Create+Task

以及调试消息（最后 3 行）：

commit: Create Task controller: tasks action: new

它应该是 "action: create" 但它不是。

真是奇葩，为此折腾了一天也解决不了。我正在使用 simple_form 顺便说一句。请帮助我......我是这里的新手:(

在注册表中

<%= simple_form_for @user, html: {class: 'form-horizontal'}, wrapper: :horizontal_input_group do |f| %>
        <%= f.input :first_name %>
        <%= f.input :last_name %>
        <%= f.input :email %>
        <%= f.input :password %>
        <%= f.input :password_confirmation %>
        <%= f.input :county_id %>
        <%= f.input :area_id %>
        <%= f.button :submit %>
        <% end %>

在post任务中

<%= simple_form_for @task, html: {class: 'form-horizontal'}, wrapper: :horizontal_input_group do |f| %>

        <%= field_set_tag '<span class="label label-info">1</span> What task do you require?'.html_safe do %>
        <%= f.input :category_id, collection: Category.order(:name), label_method: :name, value_method: :id, label: "Category", include_blank: "Select a category of task" %>
        <%= f.input :subcategory_id, collection: Category.order(:name), as: :grouped_select, group_method: :subcategories %>
        <% end %>

        <%= field_set_tag '<span class="label label-info">2</span> Tell us about the task.'.html_safe do %>
        <%= f.input :title, placeholder: 'Give a descriptive title for your task'%>
        <%= f.input :description, placeholder: 'Describe your task here...' %>
        <% end %>

        <%= field_set_tag '<span class="label label-info">3</span> What budget do you have in mind?'.html_safe do %>
        <ul class="nav nav-tabs" id="payTypeTabs">
            <%= f.input :pay_type, as: :hidden %>
            <li><a href="#fixed-price-tab" data-toggle="tab">Hire for a fixed price</a></li>
            <li><a href="#per-hour-tab" data-toggle="tab">Hire per hour</a></li>
        </ul>
        <h1></h1>

        <%= f.input :pay_offer, wrapper: :horizontal_input_group do %>
        <span class="input-group-addon">€</span>
        <%= f.input_field :pay_offer, as: :integer, class: "form-control" %>
        <span class="input-group-addon">Euro</span>
        <% end %>

        <% end %>

        <%= field_set_tag '<span class="label label-info">4</span> Where will your task take place?'.html_safe do %>    
        <%= f.input :county_id, collection: County.order(:name), label_method: :name, value_method: :id, label: "County", include_blank: "Select a category of task" %>
        <%= f.input :area_id, collection: County.order(:name), as: :grouped_select, group_method: :areas %>

        <% end %>

        <%= field_set_tag '<span class="label label-info">5</span> Set an initial appointment for this task.'.html_safe, :id => "date_time" do %>
        <% f.simple_fields_for :appointments do |b| %>


        <div class="row">

            <div class="col-md-5 col-md-offset-2"><%= b.input :start_date, label: "Start", wrapper: :horizontal_input_group do %>

                <%= b.input_field :start_date, placeholder: 'Start date', class: "form-control date start" %><span class="input-group-addon"><span class="glyphicon glyphicon-calendar"></span></span>


                <% end %>
            </div>

            <div class="col-md-5"><%= b.input :start_time, label: false, wrapper: :horizontal_input_group do %>


                <%= b.input_field :start_time, placeholder: 'Start time', as: :string, class: "form-control time start" %><span class="input-group-addon"><span class="glyphicon glyphicon-time"></span></span>

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

        <div class="row">
            <div class="col-md-5 col-md-offset-2">
                <%= b.input :end_date, label: "End", wrapper: :horizontal_input_group do %>
                <%= b.input_field :end_date, placeholder: 'End date', class: "form-control date end" %>
                <span class="input-group-addon"><span class="glyphicon glyphicon-calendar"></span></span>

                <span class="input-group-addon"><span class="glyphicon glyphicon-time"></span></span>
                <% end %>
            </div>

            <% end %>
            <% end %>

            <%= f.button :submit %>
            <% end %>

Answer 1

它在第一种情况下有效而在第二种情况下无效，这真的很奇怪。

试试这个，

<%= simple_form_for @task, url: tasks_path, method: :post, html: {class: 'form-horizontal'}, wrapper: :horizontal_input_group do |f| %>

这将强制表单使用 post 方法提交到 tasks_path，该方法会转到创建操作。让我知道它是否有效

此外，这是您的创建方法

        def create 
            @task = current_user.client_relationships.build(task_params) 
            if @task.save 
                flash[:success] = "Micropost created!" 
                redirect_to @current_user 
            else 
                render 'new' 
            end 
        end

几个问题。

1) redirect_to @current_user 没有任何意义，对吧？应该像 user_path(@current_user)

2) 你应该总是做redirect_to和return这样重定向后的代码块就不会被调用。在你的情况下，没关系，因为其余的都在 else 块中

3) 可能是 task.save 失败并呈现新的。使用调试器并检查是否到达 create

的第一行

当我单击表单中的提交按钮时，创建操作应该有效，但它是由新操作处理的

When I click submit button in my form, create action is supposed to work but it is rather processed by new action
