Koloa,
the text_field helper, takes a syntax such as :
text_field("post", "title", "size" => 20), which will build for you
the following html.
<input type="text" id="post_title" name="post[title]" size="20"
value="#{@post.title}" />
Which when received by your controller will give you a params hash as:
params[:post][:title]
sending the above prams to a Post model,
p = Post.new(params[:post]) will initialize the title method of p(a
Post instantiation) with the value typed in the html form.
You should read about helpers here: http://api.rubyonrails.com/ classes/ActionView/Helpers/FormHelper.html#M000389 and this explanation of params should be useful: http:// wiki.rubyonrails.org/rails/pages/UnderstandingRequestParameters
enjoy the ride koloa!
