Hi have a question about several tags, I do not understand if they are
RoR tags os something else
this is my form, I wrote it following the book "Simply Rails 2" in
chapter 6:
<% form_for @contacto do |f| %>
<p><label>Your Name:<br /><%= f.text_field :name, :size
=> 25
%></label></p>
<p><label>Your email:<br /> <%= f.text_field :email, :size
=> 25
%></label></p>
<p><label>Message:<br /><%= f.text_area :body, :rows =>
10, :cols => 30
%></label></p>
<p><label><%= submit_tag ''Submit'' %>
</label></p>
<% end %>
This is another form I found on "open source social network - from the
apress book"
<%= error_messages_for :page %>
<% form_for :page, :url => pages_url, :html => { :method => :post }
do
|f| -%>
<p>Title:<br /><%= f.text_field :title, :size => 60
%></p>
<p>Body:<br /><%= f.text_area :body, :rows => 20, :cols
=> 60 %></p>
<%= submit_tag ''Save'' %> or <%= link_to
''cancel'', pages_url %>
<% end -%>
questions:
- is "error_messages_for" a RoR reserved statement?
- in this expression ":url => pages_url", where does pages_url
come
from?
- in this expression ":html => { :method => :post } " why o
I need
a post?
- what is the difference between using "@contacto" and
":contacto",
in form_for. <% form_for @contacto ... or <% form_for :contacto
