Question

This is how I post a Micropost as current_user (Devise):

microposts_controller.rb:

 def create
    @user = current_user
    @micropost = @user.microposts.new(params[:micropost])
    @micropost.save
    redirect_to @micropost
  end

This is how I post a comment in a micropost:

comments_controller.rb:

  def create
    @micropost = Micropost.find(params[:micropost_id])
    @comment = @micropost.comments.create(params[:comment])
    redirect_to micropost_path(@micropost)
  end

Now I would like to post a comment as current_user

Any suggestions in order to accomplish this?

microposts/show.html.erb

<h2>Add a comment:</h2>
<%= form_for([@micropost, @micropost.comments.build]) do |f| %>
  <div class="field">
    <%= f.label :content %><br />
    <%= f.text_area :content %>
  </div>
  <div class="actions">
    <%= f.submit %>
  </div>
<% end %>

EDIT:

Not sure if you need to see this but here are the models:

comment.rb:

class Comment < ActiveRecord::Base
  attr_accessible :content, :user_id

  belongs_to :micropost
  belongs_to :user
end

micropost.rb

class Micropost < ActiveRecord::Base
  attr_accessible :title, :content

  belongs_to :user
  has_many :comments
end

user.rb

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :token_authenticatable, :encryptable, :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  # Setup accessible (or protected) attributes for your model
  attr_accessible :email, :password, :password_confirmation, :remember_me

  has_many :microposts
  has_many :comments
end

Try this in your comments_controller:

def create
  @micropost = Micropost.find(params[:micropost_id])
  comment_attr = params[:comment].merge :user_id => current_user.id
  @comment = @micropost.comments.create(comment_attr)
  redirect_to micropost_path(@micropost)
end

Until now, I think your comments didn’t have a user attached to them..

Edit – I changed :user to be :user_id. makes more sense, since we don’t have a comment yet.
