Rails posts show up blank, not saving - ruby-on-rails

Question

I tried to submit a new post and I get the error
"Title can't be blank"
So I removed the validations in my model and after trying again and posting something, the post is just blank, no data is saved whatsoever.
I don't know what to do, I stuck on this one, help!
Update!
Here is the form
<% #post.tags.build %>
<%= form_for #post, :html => {:multipart => true } do |post_form| %>
<% if #post.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#post.errors.count, "error") %> prohibited this post from being saved: </h2>
<ul>
<% #post.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= post_form.file_field :photo %>
</div>
<div class="field">
<%= post_form.label :title %><br />
<%= post_form.text_field :title %>
</div>
<div class="field">
<%= post_form.label :url %><br />
<%= post_form.text_field :url %>
</div>
<div class="field">
<%= post_form.label :company %><br />
<%= post_form.text_field :company %>
</div>
<div class="field">
<%= post_form.label :language %><br />
<%= post_form.text_field :language %>
</div>
<div class="field">
<%= post_form.label :framework %><br />
<%= post_form.text_field :framework %>
</div>
<div class="field">
<%= post_form.label :details %><br />
<%= post_form.text_area :details %>
</div>
<h2>Tags</h2>
<%= render :partial => 'tags/form' ,
:locals => {:form => post_form } %>
<div class="actions">
<%= post_form.submit %>
</div>
<% end %>
here is the controller:
class PostsController < ApplicationController
http_basic_authenticate_with :name => "franklinexpress", :password => "osxuser8", :except => [:index, :show, :new, :edit]
#def search
# #posts = Post.search(params[:search])

#posts = Post.search(params[:search])

end

#post = Post.find(params[:id])
respond_to do |format|

def create
#post = Post.new(params[:post])
respond_to do |format|
if #post.save
format.html { redirect_to #post, notice: 'Post was successfully created.' }
format.json { render json: #post, status: :created, location: #post }
else
format.html { render action: "new" }
format.json { render json: #post.errors, status: :unprocessable_entity }
end
end
end
# PUT /posts/1
# PUT /posts/1.json
def update
#post = Post.find(params[:id])
respond_to do |format|
if #post.update_attributes(params[:post])
format.html { redirect_to #post, notice: 'Post was successfully updated.' }
format.json { head :ok }
else
format.html { render action: "edit" }
format.json { render json: #post.errors, status: :unprocessable_entity }
end
end
end
# DELETE /posts/1
# DELETE /posts/1.json
def destroy
#post = Post.find(params[:id])
#post.destroy
respond_to do |format|
format.html { redirect_to posts_url }
format.json { head :ok }
end
end
end
in my model:
class Post < ActiveRecord::Base
validates :title, :presence => true
validates :url, :presence => true
validates :company, :presence => true
validates :language, :presence => true
validates_attachment_size :photo, :less_than => 4.megabytes

has_many :tags

attr_accessor :photo_content_type
attr_accessor :photo_file_size
attr_accessor :photo_updated_at
attr_accessible :photo
accepts_nested_attributes_for :tags, :allow_destroy => :true,
:reject_if => proc { |attrs| attrs.all? { |k, v| v.blank? } }
#paperclip-------------------------------
has_attached_file :photo,

:path => ":rails_root/public/assets/images/:id/:style/:basename.:extension"
#:style => {:small => "150x200>"}
def self.search(search)
if search
where('title LIKE ?', "%#{search}%")
# find(:all, :conditions => ['title LIKE ?', "%#{search}%"])
else
all
end
end
end
and in new.html.erb:
<div id="header-wrap">
<%= image_tag("walLogotiny.png") %>
<div id="searchbartop">
<%= form_tag posts_path, :method => :get do%>
<%= text_field_tag :search, params[:search] ,"size" => 100 %>
<%= submit_tag "Search", :name => nil %>
<% end %>
</div>
</div>
<div id="container">
<h2>New Site Submission</h2>
<%= render 'form' %>
<%= link_to 'Back', posts_path %>
</div>

With this line in your model:
attr_accessible :photo
You make only the photo attribute mass-assignable. All other attributes, including the title, are dropped when you create a new post.
Try this:
attr_accessible :photo, :title
It will now accept the title, but not the other attributes.
edit: didn't see your own comment above, but you figured it out already.
