Rails: Comment Model - Connected to a Micropost_id and User_id - ruby-on-rails

Question

EDIT
The Routing Error has disappeared thanks to carlosramireziii who helped changed the Form to
<%= form_for (#micropost) do |f| %>
<%= fields_for :comments do |ff| %>
<%= ff.text_area :content %>
<% end %>
<div class="CommentButtonContainer">
<%= f.submit "Comment" %>
</div>
<% end %>
But the issue now is that the post will not save, any suggestions?
I am currently making a comments model that is connected to a:
micropost_id :integer and user_id :integer
The problem that I continue to receive is when I post something I get this in return:
Routing Error
No route matches [POST] "/microposts/comments"
This is my routes.eb
Project::Application.routes.draw do
resources :microposts do
resources :comments
end
This is the Comment Form
<%= form_for([#micropost, #micropost.comments.new]) do |f| %>
<%= f.text_area :content %>
<div class="CommentButtonContainer">
<%= f.submit "Comment" %>
</div>
<% end %>
This is the Comment Template
<%= div_for comment do %>
<div class='UserCommentContainer'>
<div class='UserComment'>
<div class='UserName sm'>
Anonymous
</div>
<div class='UserCommentText'>
<%= comment.content %>
</div>
</div>
</div>
<% end %>
And finally this is what is inside the Micropost
<div id='CommentContainer' class='Condensed2'>
<div class='Comment'>
<%= render "comments/form" %>
</div>
<div id='comments'>
<%= render #micropost.comments %>
</div>
</div>
Everything else related to the comments model and controller I have posted below, I have been mulling around this for a long time and could really use help, thank you!
Comments Model
class Comment < ActiveRecord::Base
attr_accessible :content
belongs_to :micropost
validates :content, presence: true, length: { maximum: 140 }
validates :user_id, presence: true
validates :micropost_id, presence: true
default_scope order: 'comments.created_at DESC'
end
Micropost Model
class Micropost < ActiveRecord::Base
belongs_to :user
has_many :comments
validates :user_id, presence: true
end
User Model
class User < ActiveRecord::Base
has_many :microposts
has_many :replies, :through => :microposts, :source => :comments
end
Comments Controller
class CommentsController < ApplicationController
def create
#comment = #micropost.comments.new(params[:comment])
if #comment.save
redirect_to #user
else
redirect_to #user
end
end
end
User Controller
class UsersController < ApplicationController
def show
#user = User.find(params[:id])
#micropost = Micropost.new
#comment = #micropost.comments.new
#microposts = #user.microposts.paginate(page: params[:page])
end
end

I believe the problem is that you are trying to save a new comment on a micropost that hasn't been saved yet. Since you have your comments routes nested underneath the microposts routes, the micropost needs to exist before you can create a new comment.
If you want to create both objects in the same form, you need to use nested model attributes.
Micropost
class Micropost < ActiveRecord::Base
belongs_to :user
has_many :comments
accepts_nested_attributes_for :comments
validates :user_id, presence: true
end
Form
<%= form_for(#micropost) do |f| %>
<%= f.fields_for :comments do |ff %>
<%= ff.text_area :content %>
<% end %>
<div class="CommentButtonContainer">
<%= f.submit "Comment" %>
</div>
<% end %>
