I ll start with the PATTERNS tab because there are several topics I need to cover first before moving to general and punctuation SETTINGS Click the NODE PATHS link to view URL replacement patterns for all content types, as shown in Figure 7-2 You can set both the Default path pattern and the content-type specific pattern from this fieldset All system content types are listed on this page and are blank by default; if a content type does not have a pattern, then it displays the Default path pattern Click the REPLACEMENT PATTERNS link to view a list of tokens that automatically generate values depending on the node These are placed into the fields above (such as Default path pattern) and include a number of values, such as the node s ID, content type, taxonomy term, created date, and more.

return save(bid); } private Bid save(Bid bid) { entityManager.persist(bid); return bid; } }

The true magic of the code in listing 2.8 lies in the EntityManager interface. One interesting way to think about the EntityManager interface is as an interpreter between the object-oriented and relational worlds. The manager reads the ORM mapping annotations like @Table and @Column on the Bid entity and figures out how to save the entity into the database. The EntityManager is injected into the PlaceBid bean through the @PersistenceContext annotation b. Similar to the name parameter of the @Resource annotation in listing 2.5, the unitName parameter of the @PersistenceContext annotation points to the persistence unit specific to ActionBazaar. A persistence unit is a group of entities packaged together in an application module. You ll learn more about persistence units in chapters 9 and 11. In the save method, the EntityManager persist method is called to save the Bid data into the database C. After the persist method returns, a SQL statement much like the following is issued against the database to insert a record corresponding to the bid:

6. Locate the Projection section and change the Y value to 160, as in Figure 7-13.

INSERT INTO BIDS (BID_ID, BID_DATE, BIDDER_ID, BID_AMOUNT, ITEM_ID) VALUES (52, NULL, 60, 20000.50, 100)

The Internal feed alias te x t setting is used to generate aliases to specific nodes RSS feeds When building and managing a site, there are times when you create nodes before configuring Pathauto Selecting BULK UPDATE tab to automatically create URLs for each node without an alias upon save There are also times when you make configuration changes to Pathauto and you want to update all old URLs to the new path pattern The easiest way to do this is to click the DELETE ALIASES tab, delete all the content aliases, and then go back and Select the types of un-aliased paths for which to generate URL aliases from the BULK UPDATE tab.

It might be instructive to look back at listing 2.7 now to see how the EntityManager figures out the SQL to generate by looking at the object-relational mapping annotations on the Bid entity. Recall that the @Table annotation specifies that the bid record should be saved in the BIDS table while each of the @Column annotations in listing 2.7 tells JPA which Bid entity field maps to which column in the BIDS table. For example, the bidId property maps to the BIDS.BID_ID column, the bidAmount property maps to the BIDS.BID_AMOUNT column, and so on. As we

Having trouble finding properties in the Properties panel You can always start typing whatever property you are looking for in the Search field at the top of the Properties panel. This will filter your properties for you. For example, say you want the Projection Transform property. You can type Projection in the Search field, and every property with the letters Projection in it will be displayed. Other properties will be hidden. There is also a search field for the Asset Library.
