The final association Cake can recognize for database table relationships is the has and belongs to many relationship. This relationship is powerful but also a little difficult to master. The more you experiment with has and belongs to many associations, the easier it will be to use them in your applications. In short, I ve already discussed a one-to-one relationship with the hasOne association, and the hasMany association shows you how a one-to-many relationship is managed in Cake. What about a many-to-many relationship

taken to receive the response from the server, because the entire page is still sent. The only difference is that the page is updated without a distracting flicker. Small as that advantage seems, it can make a major difference in how your web page feels to the person using it.

As you ve seen, when the UpdatePanel performs its callback, the web page code runs in exactly the same way as if the page had been posted back. The only difference is the means of communication (the page uses an asynchronous call to get the new data) and the way the received data is dealt with (the UpdatePanel refreshes its inner content, but the remainder of the page is not changed). For that reason, you don t need to make significant changes to your server-side code or deal with new error conditions.

That said, problems can occur when performing an asynchronous postback just as they do when performing a synchronous postback. To find out what happens, you can add code like this to the event handler for the Page.Load event, which causes an unhandled exception to occur when an asynchronous callback takes place: If Me.IsPostBack Then Throw New ApplicationException("This operation failed.") End If When the web page throws an unhandled exception, the error is caught by the ScriptManager and passed back to the client. The client-side JavaScript then throws a JavaScript error. What happens next depends on your browser settings, but usually browsers are configured to quietly suppress JavaScript errors. In Internet Explorer, an Error on page message appears in the status bar that indicates the problem. If you double-click this notification, a dialog box appears with the full details, as shown in Figure 25-3.

Many web sites use tags to order their content. Many blogs, rather than assigning one category to a post, will have a list of tags that can be assigned multiple times to multiple stories, and vice versa. This is a many-to-many relationship between posts and tags. One post can have many tags, and each tag can belong to many posts. Structurally, the database can handle many-to-many relationships only if there is a third table that saves these associations. In the post-to-tag example, a third table named something like posts_tags would be created. In it would be just two fields: post_id and tag_id. By having a third table, you maintain the flexibility needed to list as many relationships as the application would need to save; there is no limit to the number of associations in either direction because the third table can continually save more records. As you can imagine, Cake saves a great deal of time in managing this association. Just like the $hasOne and $hasMany attributes, you create a has and belongs to many association by entering the $hasAndBelongsToMany attribute in the model. You can also test has and belongs to many associations in the scaffold. Rather than view a select menu for a one-to-many relationship, Cake s scaffolding will render a multiple-select menu. In this way, you can test the association in the same manner that you tested the has many relationship earlier.

Figure 25-3. Displaying a client-side message about a server-side error There s another option for dealing with the errors that occur during an asynchronous postback. You can use custom error pages, just as you do with ordinary web pages. All you need to do is add the <customErrors> element to the web.config file, as you did in 8. For example, here s a <customErrors> element that redirects all errors to the page named ErrorPage.aspx: <customErrors defaultRedirect="ErrorPage.aspx" mode="On"></customErrors> Now, when the PageRequestManager is informed of an error it will redirect the browser to ErrorPage.aspx. It also adds an aspxerrorpath query string argument to the URL that indicates the URL of the page where the problem originated, as shown here: http://localhost/Ajax/ErrorPage.aspx aspxerrorpath=/Ajax/UpdatePanels.aspx
