Ruby on Rails - Render partial from another controller - html

Question

I'm new to rails and I've looked around and none of the solutions on here I've found seem to work. I feel that I am missing something crucial.
I am trying to render a partial from /views/names/_form.html.erb into another file with a different controller /views/posts/index.html.erb. I keep getting the following error.
app/views/names/_form.html.erb where line #1 raised:
First argument in form cannot contain nil or be empty
Extracted source (around line #1):
<%= form_for(#name) do |f| %>
<% if #name.errors.any? %>
<%= pluralize(#name.errors.count, "error") %> prohibited this >name from being saved:
My HTML code is as follows:
<div class="modal" id="myModal">
<h1>Company Name</h1>
<div class="modal-body">
<%= render :partial => '/names/form' %>
...etc...
My Names controller is as follows:
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
My Posts controller is as follows:
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
And finally this is my routes file
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'
Thank you so much for your help.

Add the following line in your post/index method. when to render the partial in your view html , your form try to find the #name object which not found in the post/index method . So we need to initialise #name with new Name object.
def index
#posts = Post.all
#name = Name.new
end
