既然最初的问题已经解决了，我将添加一些其他的方法来实现这一点。你自己完成这一点需要做更多的工作，而且你也不会拥有一些gem可以给你的所有功能。另一方面，它的代码要少得多，而且你可以完全控制一切。此外，如果你只需要有一个字段是可编辑的，安装gem和jquery的开销太大。
设置：

# rails v7.0.4.2
$ rails new hello_edit_in_place -c tailwind
$ cd hello_edit_in_place
$ bin/rails g scaffold User email first_name last_name --skip-timestamps
$ bin/rails db:migrate
$ bin/rails runner "User.create(email: 'admin@localhost', first_name: 'super', last_name: 'admin')"
$ open http://localhost:3000/users
$ bin/dev

class User < ApplicationRecord
  validates :email, presence: true, length: {minimum: 3}
end

Turbo帧

作为一个简单的例子，我将只修改默认表单，而不涉及控制器：
一个二个一个一个
就是这样，每个属性都被呈现，可编辑，电子邮件显示验证错误。另外，因为所有turbo_frame_tag都有唯一的id，所以索引页面上的所有内容都可以与多个用户一起使用。

涡轮流

您也可以使用turbo_stream来获得更大的灵活性，使其更具动态性，但它更像是一个设置。此外，添加在适当位置编辑全名的功能，将 * first_name * 和 * last_name * 字段放在一起：

# config/routes.rb

# NOTE: to not mess with default actions, add new routes
resources :users do
  member do
    get "edit_attribute/:attribute", action: :edit_attribute, as: :edit_attribute
    patch "update_attribute/:attribute", action: :update_attribute, as: :update_attribute
  end
end

# app/views/users/_user.html.erb

# Renders user attributes.
# Required locals: user.

<%= render "attribute", user:, attribute: :email %>
<%= render "attribute", user:, attribute: :name %>

# app/views/users/_attribute.html.erb

# Renders editable attribute.
# Required locals: attribute, user.

<%= tag.div id: dom_id(user, attribute) do %>
  <%= tag.div attribute, class: "mt-4 block mb-1 font-medium" %>
  # NOTE: to make a GET turbo_stream request              vvvvvvvvvvvvvvvvvvvvvvvvvv
  <%= link_to edit_attribute_user_path(user, attribute:), data: {turbo_stream: true} do %>
    # far from perfect, but gotta start somewhere
    <% if user.attribute_names.include? attribute.to_s %>
      <%= user.public_send(attribute) %>
    <% else %>
      # if user doesn't have provided attribute, try to render a partial
      <%= render attribute.to_s, user: %>
    <% end %>
  <% end %>
<% end %>

# app/views/users/_name.html.erb

# Renders custom editable attribute value.
# Required locals: user.

<%= user.first_name %>
<%= user.last_name %>

# app/views/users/_edit_attribute.html.erb

# Renders editable attribute form.
# Required locals: attribute, user.

<%= form_with model: user, url: update_attribute_user_path(user, attribute:) do |f| %>
  <% if user.attribute_names.include? attribute.to_s %>
    <%= f.text_field attribute %>
  <% else %>
    # NOTE: same as before but with `_fields` suffix,
    #       so this requires `name_fields` partial.
    <%= render "#{attribute}_fields", f: %>
  <% end %>
  <%= f.submit "save" %>
<% end %>

# app/views/users/_name_fields.html.erb

# Renders custom attribute form fields.
# Requires locals:
#   f - form builder.

<%= f.text_field :first_name %>
<%= f.text_field :last_name %>

# app/controllers/users_controller.rb

# GET /users/:id/edit_attribute/:attribute
def edit_attribute
  attribute = params[:attribute]
  respond_to do |format|
    format.turbo_stream do
      # render form
      render turbo_stream: turbo_stream.update(
        helpers.dom_id(user, attribute),
        partial: "edit_attribute",
        locals: {user:, attribute:}
      )
    end
  end
end

# PATCH  /users/:id/update_attribute/:attribute
def update_attribute
  attribute = params[:attribute]
  attribute_id = helpers.dom_id(user, attribute)
  respond_to do |format|
    if user.update(user_params)
      format.turbo_stream do
        # render updated attribute
        render turbo_stream: turbo_stream.replace(
          attribute_id,
          partial: "attribute",
          locals: {user:, attribute:}
        )
      end
    else
      format.turbo_stream do
        # render errors
        render turbo_stream: turbo_stream.append(
          attribute_id,
          html: (
            helpers.tag.div id: "#{attribute_id}_errors" do
              # FIXME: doesn't render `first_name` `last_name` errors
              helpers.safe_join user.errors.full_messages_for(attribute), helpers.tag.br
            end
          )
        )
      end
    end
  end
end

  @user ||= User.find(params[:id])
