surrounding template. This way we can, for example, use the same partial form template for both creating a new author and editing an existing author. If used together with a :collection option, the call will render the template once for each element of the container passed with the option. You will see an example of this in the Listing Authors section later in this chapter, where we output a similar table row for each author we have in the system. More information about rendering partials in Rails can be found in the Rails API docs at http://api.rubyonrails.org/classes/ActionController/Base.html#M000206.

One simple type of database can be stored in a text file in a format commonly known as CSV. CSV stands for Comma-Separated Values, and means that for each item of data you re storing, you can have multiple attributes separated with commas. The dummy data in your text.txt file in the previous section used CSV data. To recap, text.txt initially contained this code:

Fred Bloggs,Manager,Male,45 Laura Smith,Cook,Female,23 Debbie Watts,Professor,Female,38

We can also send the message and wait for a reply. If the reply comes within the timeout period, the method returns Some(response), otherwise the method returns None:

Each line represents a different person, and commas separate the attributes relating to each person. The commas allow you to access (and change) each attribute separately. Ruby s standard library includes a library called csv that allows you to use text files containing CSV data as simple databases that are easy to read, create, and manipulate.

val msgs2: Option[List[String]] = ChatServer2 ! (500, GetMessages) match { case Some(Messages(msg)) => Some(msg) case Some(_) => None // got a response we didn't understand case None => None // timeout }

The template first creates a <form> tag with the form_tag helper, pointing it to the create action. Then it renders the actual form, which we will implement in a minute using a partial template. Next, our template outputs a submit button for the form and closes it. Finally, we show a link to the index page listing all the authors (although we haven t implemented that page yet). Next, we need to create the partial template for the actual form. Create a new file app/views/admin/author/_form.rhtml and add the following form to it: <%= error_messages_for 'author' %> <p><label for="author_first_name">First name</label><br/> <%= text_field 'author', 'first_name' %></p> <p><label for="author_last_name">Last name</label><br/> <%= text_field 'author', 'last_name' %></p> In the form, we use two useful Rails helper methods: error_messages_for outputs the validation error notification if there are problems with the form input. text_field is a form helper that creates a text field element for a given object attribute in this case, author s first and last names. The real value of text_field can be seen when a user inputs something invalid to the form. Rails will automatically mark the field with CSS class fieldWithErrors, so you can use CSS to make the field stand out from other fields. If we run our functional test again, we can see it pass. Opening http://localhost:3000/ admin/author/new in a browser, we can see that we have implemented the first part of adding a new author, as shown in Figure 2-1.

The CSV class provided by csv manages the manipulation of the data for you:

["Fred Bloggs", "Manager", "Male", "45"] ["Laura Smith", "Cook", "Female", "23"] ["Debbie Watts", "Professor", "Female", "38"]

In the previous example, we send the GetMessages message to ChatServer2 and wait 500 milliseconds for a response. Let s look at the messages and the ChatServer2 implementation:

You open the text.txt file by using CSV.open, and each line (that is, each individual person in the file) is passed into the block one by one. The inspect method demonstrates that each entry is now represented in array form. This makes it easier to read the data than when it was in its plain text form. You can also use CSV alongside the File class:
