【问题描述】:
我是 Rails 新手,我环顾四周,发现这里的解决方案似乎都不起作用。我觉得我错过了一些重要的东西。
我正在尝试将 /views/names/_form.html.erb 中的部分内容渲染到具有不同控制器 /views/posts/index.html.erb 的另一个文件中。我不断收到以下错误。
app/views/names/_form.html.erb 其中第 1 行提出:
表单中的第一个参数不能包含 nil 或为空 提取的源代码(第 1 行附近):
禁止保存此>name:
我的HTML代码如下:
<div class="modal" id="myModal">
<h1>Company Name</h1>
<div class="modal-body">
<%= render :partial => '/names/form' %>
...etc...
我的名字控制器如下:
class NamesController < ApplicationController
before_action :set_name, only: [:show, :edit, :update, :destroy]
def index
@names = Name.all
end
def show
end
def new
@name = Name.new
end
def edit
end
def create
@name = Name.new(name_params)
respond_to do |format|
if @name.save
format.html { rredirect_to @name, notice: 'Post created' }
format.json { render :show, status: :created, location: @name }
else
format.html { render :new }
format.json { render json: @name.errors, status: :unprocessable_entity }
end
end
end
我的 Posts 控制器如下:
class PostsController < ApplicationController
before_action :set_post, only: [:show, :edit, :update, :destroy]
before_action :authenticate_user!, except: [:index]
# before_filter :first_time_visiting?
# GET /posts
# GET /posts.json
def index
@posts = Post.all
end
# GET /posts/1
# GET /posts/1.json
def show
@posts = Post.all
end
# GET /posts/new
def new
@post = current_user.posts.build
end
# GET /posts/1/edit
def edit
end
# POST /posts
# POST /posts.json
def create
@post = current_user.posts.build(post_params)
respond_to do |format|
if @post.save
format.html { redirect_to @post, notice: 'Post was successfully created.' }
format.json { render :show, status: :created, location: @post }
else
format.html { render :new }
format.json { render json: @post.errors, status: :unprocessable_entity }
end
end
end
最后这是我的路线文件
Rails.application.routes.draw do
resources :posts
devise_for :users
resources :names
root 'index#home'
get "about" => 'index#about'
get "contact" => 'index#contact'
get 'closings' => 'index#closings'
get 'signin' => 'users#sign_in'
非常感谢您的帮助。

对不起,澄清html代码是为views/posts/index.html.erb
