text_field(object_name, method, options = {}) public

Returns an input tag of the "text" type tailored for accessing a specified attribute (identified by method) on an object assigned to the template (identified by object). Additional options on the input tag can be passed as a hash with options.

Examples (call, result): 

  text_field("post", "title", "size" => 20)
    <input type="text" id="post_title" name="post[title]" size="20" value="#{@post.title}" />

Force initial value

If you want to force an initial value for your text_field which is normally based on your object attribute value, you can use :

text_field :ecard, :sender, :value => 'contact@host.com'

Alternative force initial value

@Bounga - Thanks for the suggestion. Didn’t know about that method. An alternative method I have used is just to assign the default value to the object in your controller. For example your “new” action might now look like:

def new
  @ecard = Ecard.new params[:ecard]
  @ecard.sender ||= 'contact@host.com'
end

Re: Force initial value

An alternative to @eric_programmer’s would be to extract it entirely from the controller logic…

class Person
  def sender
    self[:sender] || 'contact@host.com'
  end
end

There are a ton of ways to do it, but making this a business logic decision will let you get the same logic from any possible implementation angle. Scripts, web service, etc.
