syntax error, unexpected '\n', expecting :: or '[' or '.' - ruby-on-rails

Question

I am trying to have an image uploader on my app using Paperclip, and my only problem is that I keep getting an Undefined Method error.
I have it set up on github, https://github.com/BBaughn1/savagelysaving
My User Controller:
class UserController < ApplicationController
def create
#user = User.create( user_params )
end
def destroy
#user.image = nil
#user.save
end
private
# Use strong_parameters for attribute whitelisting
# Be sure to update your create() and update() controller methods.
def user_params
params.require(:user).permit(:image)
end
end
Then my Show.html.erb file:
<div id="post_content">
<h1 class="title">
<%= #post.title %>
</h1>
<p class="date">
Submitted <%= time_ago_in_words(#post.created_at) %> Ago
<% if user_signed_in? %>
| <%= link_to 'Edit', edit_post_path(#post) %>
| <%= link_to "Delete", post_path(#post), method: :delete, data: { confirm: 'Are you sure?' } %>
<% end %>
</p>
<p class="body">
<%= #post.body %>
<%= image_tag #post.image.url(:medium) %>
</p>
<div id="comments">
<%= render 'disqus' %>
</div>
</div>
In my post.rb file:
class Post < ActiveRecord::Base
has_many :comments, dependent: :destroy
validates :title, presence: true, length: { minimum: 5 }
validates :body, presence: true
attr_accessor :image
has_attached_file :image, styles: { medium: "300x300>", thumb: "100x100#" }, default_url: "/images/:style/missing.png"
validates_attachment_content_type :image, content_type: /\Aimage\/.*\Z/
end
in my development.rb file:
Rails.application.configure do
***STUFF***
Paperclip.options[:command_path] = "/usr/local/bin/"
end
and posts controller:
class PostsController < ApplicationController
# before_action :find_post, only: [:show, :edit, :update, :destroy]
before_action :authenticate_user!, except: [:index, :show]
def index
#posts = Post.all.order('created_at DESC')
end
def new
#post = Post.new
attr_accessor :image
end
def create
attr_accessor :image
#post = Post.new(post_params)
if #post.save
redirect_to #post
else
render 'new'
end
end
def show
#post = Post.find(params[:id])
end
def edit
#post = Post.find(params[:id])
end
def update
#post = Post.find(params[:id])
attr_accessor :image
if #post.update(params[:post].permit(:title, :body, :image))
redirect_to #post
else
render 'edit'
end
end
def destroy
#post = Post.find(params[:id])
#post.destroy
redirect_to root_path
end
private
def post_params
params.require(:post).permit(:title, :body, :image)
end
end

Answer 1

There is no avatar attribute in your user model but there is an image attribute in your post model.
If you remove below code from user model and move it to post model, the image upload will work
has_attached_file :image, styles: { medium: "300x300>", thumb: "100x100>" }, default_url: "/images/:style/missing.png"
validates_attachment_content_type :image, content_type: /\Aimage\/.*\Z/
This should fix the bug.

Answer 2

I looked at your github to see if you made the same mistake I did. I think you forgot to add imagemagick to your development.rb file. When you install imagemagick on your local machine, it need to see where it's installed; which convert where show where. It might look like this Paperclip.options[:command_path] = "/usr/local/bin/" if not, just copy what it show you and edit what's in the quotes " ".
I hope that helps I know I was having some trouble getting it to work.
