Instance Method Details

#form_for(obj, attrs = {}, &block) ⇒ Object

Generates a resource specific form tag which accepts a block, this also provides automatic resource routing.

<% form_for :person, :action => url(:people) do %>
  <%= text_control :first_name, :label => 'First Name' %>
  <%= text_control :last_name,  :label => 'Last Name' %>
  <%= submit_button 'Create' %>
<% end %>

The HTML generated for this would be:

<form action="/people/create" method="post">
  <label for="person[first_name]">First Name</label><input id="person_first_name" name="person[first_name]" size="30" type="text" />
  <label for="person[last_name]">Last Name</label><input id="person_last_name" name="person[last_name]" size="30" type="text" />
  <input name="commit" type="submit" value="Create" />
</form>

end

#form_tag(attrs = {}, &block) ⇒ Object

Generates a form tag, which accepts a block that is not directly based on resource attributes

<% form_tag(:action => url(:controller => "foo", :action => "bar", :id => 1)) do %>
  <%= text_field :name => 'first_name', :label => 'First Name' %>
  <%= submit_button 'Create' %>
<% end %>

The HTML generated for this would be:

<form action="/foo/bar/1" method="post">
  <label for="first_name">First Name</label><input id="first_name" name="first_name" size="30" type="text" />
  <input name="commit" type="submit" value="Create" />
</form>
