Rails 5 编辑表单找不到嵌套模型的路径 - 路由错误
Rails 5 Edit Form can't find path with nested model - routing error
我有一个控制器可以处理表单的新操作和编辑操作，该表单的模型接受另一个表单的嵌套属性。 'new' 动作效果很好。但是，当我转到编辑表单并提交时，它显示：
Routing Error
No route matches [PATCH] "/admins/employees"
此外，当我在编辑页面时，它不会在那里显示所有当前信息。只有 'email' 显示数据库中当前的内容。通常，编辑页面显示数据库中当前与这些属性相关的内容，但此表单只是空白，电子邮件除外。不幸的是，谷歌搜索这个特定问题并没有找到任何相关或有用的信息。我认为 Rails 3 或其他东西很接近，但不适合我的问题。我正在使用 Rails 5.1.
我的代码如下：
员工控制器
class Admins::EmployeesController < UserActionsController
def index
@employees = User.where(:company => @current_company)
end
def edit
@employee = User.find(params[:id])
end
def update
@employee = User.find(params[:id])
@employee.assign_attributes(employee_params)
if @employee.save
flash[:notice] = "Employee was updated."
redirect_to root_path
else
flash.now[:alert] = "There was an error saving the information. Please try again."
render :edit
end
end
def show
@employee = User.find(params[:id])
end
def new
@employee = User.new
end
def create
@employee = User.new(employee_params)
@employee.company = @current_company
if @employee.save
redirect_to admins_employees_path
else
render :new
end
end
private
def employee_params
params.require(:user).permit(:email, :password, :profile_attributes => [:firstName, :lastName, :title, :fullTime, :startDate])
end
end
Edit.html.erb
<!--BODY-->
<%= render partial: 'form', locals: { employee: @employee, profile_attributes: :profile_attributes } %>
<!--BODY END-->
_form.html.erb
<%= form_for employee, url: admins_employees_path do |f| %>
<div class="col-4 mb-3">
<% if employee.errors.any? %>
<div class="alert alert-danger">
<h4><%= pluralize(employee.errors.count, "error") %>.</h4>
<ul>
<% employee.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="row">
<div class="col p-0 mr-3">
<div class="form-group">
<%= f.label :email %>
<%= f.text_field :email, class: 'form-control' %>
</div>
<div class="form-group">
<%= f.label :password %>
<%= f.text_field :password, class: 'form-control' %>
</div>
<%= f.fields_for profile_attributes do |user_f| %>
<div class="form-group">
<label>First Name</label>
<%= user_f.text_field :firstName, :placeholder => 'First Name', class: 'form-control' %>
</div>
<div class="form-group">

<div class="form-group">

<%= user_f.text_field :startDate, :placeholder => 'Start Date', class: 'form-control' %>
</div>
<% end %>
</div>
<div class="col-12 p-0">
<%= f.submit "Submit", :class => 'btn btn-primary btn-block btn-lg' %>
</div>
</div>
</div>
<% end %>
谢谢！

您可以通过稍微更改代码来消除所有这些错误。
edit.html.erb :
<%= form_for employee, url: admins_employee_path(params[:id]) do |f| %>
<%= render partial: 'form', locals: { employee: @employee, profile_attributes: :profile_attributes, f: f } %>
<% end %>
new.html.erb :
<%= form_for employee, url: admins_employees_path do |f| %>
<%= render partial: 'form', locals: { employee: @employee, profile_attributes: :profile_attributes, f: f } %>
<% end %>
并从 form 部分
中删除表格行和结尾
为了您的信息，我想补充一点，rails 是如此切肉刀，以至于它不需要告诉 url 和 form_for，原因是 [= 中的对象30=]m 是新的，它会在提交时自动点击创建操作，如果对象已经存在，它将在提交时点击更新操作。这就是 partial 和 dry 概念的美妙之处 rails 和 form_for 所以这里
您有一个部分 form 用于编辑和新操作
只需在此处更改一行：- 不需要每次都告诉 url 新的和更新操作。
<%= form_for employee do |f| %>
//your codes for form
<%end%>
也不需要传递 nested_attribites 局部变量，因为它会自动获取 f 对象
<%= render partial: 'form', locals: { employee: @employee } %>
但对于新操作，您需要 build nested_attribute object
def new
@employee = User.new
@employee.profile_attributes.build
end
