Ruby-On-Rails how to display image uploaded by user

I am using Carrierwave so that a user can upload an image. I am making a blog website. I have no errors but the image is not appearing. I want the image to appear in the post VIEW. Here is my code:

Post.rb

mount_uploader :image, ImageUploader

Posts _form.html.erb

  <div>
    <%= form_for @post do |f|%>
    <%= f.label :image %>
    <%= f.file_field :image %>
  </div>

image_uploader.rb

  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

  def extension_white_list
    %w(jpg jpeg gif png)
  end

Posts show.html.erb

<strong>Image:</strong>
    <%= image_tag @post.image_url%>
</p>

When I run my application and view a post it just says Image: with no image underneath it.

UPDATE:

I installed ImageMagick/GraphicsMagick, and when I go to save post it says:

1 error prohibited this post from being saved:
Image Failed to manipulate with MiniMagick, maybe it is not an image? `Original Error: ImageMagick/GraphicsMagick is not installed`

and underneath it displays the image but it wont save the post.

While form_for sets encoding multipart automatically, but in my projects I still define it. Try this:

<%= form_for(@post, hmtl: { multipart: true } ) do |f| %>
