Rails：如何强制表单发布而不是修补？ [英] Rails: How to force a form to post rather than patch?

问题描述

项目/展览上的表单创建新任务的效果很好，但是，在项目/展示和任务/在任务/显示它想要编辑任务，因为我需要从我的任务控制器的show动作中调用任务ID。

我需要修改这个表单总是创建新的任务。

我试过 method：post 但是rails仍然插入< ; input type =hiddenname =_ methodvalue =patch/> 放入HTML中。

和形式：

pre $ code＃任务控制器
def show
@projects = Project.all
@project = Project.find（params [：project_id]）
@task = Task.find（params [：id]）
@tasks = @ project.tasks.all
end

def创建
@project = Project.find（params [：project_id]）
@task = @ project.tasks.new（task_params）
@ task.save
redirect_to @project
结束

#Form
<％= form_for（[@ project，@task]）do | f | ％GT;
<％= f.text_field：title％>
<％= f.submit％>
<％end％>

有没有办法强制rails始终从这个表单创建新任务？

解决方案

尝试使用现有任务的属性分配新任务对象。

 ＃任务控制器
 def show 
 @projects = Project.all 
 @project = Project.find（params [：project_id]）
 @task = Task.find（params [：id]）
 @new_task = Task.new（title： @ task.title）
 @tasks = @ project.tasks.all 
结束
 
＃... 
 
 #Form 
< b< ;％= form_for（[@ project，@new_task]）do | f | ％GT; 
<％= f.text_field：title％> 
<％= f.submit％> 
<％end％> 
  

I have a form for creating tasks which is displayed on both projects/show and tasks/show.

The form on projects/show creates new tasks fine, but on tasks/show it wants to edit the task, since I need to call the task ID from within the show action of my tasks controller.

I need to modify this form to always create new tasks.

I tried method: post but rails still inserts <input type="hidden" name="_method" value="patch" /> into the HTML.

Here are my controllers and the form:

# Tasks Controller
def show
   @projects = Project.all
   @project = Project.find(params[:project_id])
   @task = Task.find(params[:id])
   @tasks = @project.tasks.all
end

def create
   @project = Project.find(params[:project_id])
   @task = @project.tasks.new(task_params)
   @task.save
   redirect_to @project
end

#Form
  <%= form_for([@project, @task]) do |f| %>
      <%= f.text_field :title %>
      <%= f.submit %>
  <% end %>

Is there any way to force rails to always create new tasks from this form?

解决方案

Try assigning a new task object using the existing task's attributes. That way the form will POST rather than PATCH:

# Tasks Controller
def show
   @projects = Project.all
   @project = Project.find(params[:project_id])
   @task = Task.find(params[:id])
   @new_task = Task.new(title: @task.title)
   @tasks = @project.tasks.all
end

# ...

#Form
<%= form_for([@project, @new_task]) do |f| %>
    <%= f.text_field :title %>
    <%= f.submit %>
<% end %>
