</a></p> Finally, you ll need to update the listhtml template so that the pager() method of the paginator is named pager() rather than commentr() after the automatic rename and so that the paginator displays information relevant to the comments rather than pages Here s the updated version:.

When working with databases with several tables, it is important to have a normalized structure. Under normal circumstances, no information should appear more than once. An example of the opposite is if the salaries table contains the lastname and id. In such a case, changing the lastname requires two UPDATE calls. The tables used this far are pretty simple, but try to remember to keep data in only one place (which might sometimes require additional id columns just to tie things together). This is a time well spent because it makes the structure easier to work with. This introduction to SQL only scratches the surface of database design and join statements. There are many more aspects to take into account before implementing a complex database, and there are numerous other ways of joining tables and creating relationships. Some of them are standardized, and others are very dependent on the database server you are using. Before implementing any complex database design I suggest that you consult you database server s documentation as well as books focusing on the topic.

Now that we have covered some basics of how the Internet works, we will introduce our code example, a simple web server that we will be using to illustrate various security design concepts later in this chapter and the next. Before we present the code for the simple web server, we ll briefly review the basics of how web servers work. We have intentionally simplified our explanation so that we can focus on only the essential details, so if you re a web veteran, please don t be alarmed at how many details we ve omitted!

<%inherit file="/base/index.html" /> <%def name="heading()"><h1>Comment List</h1></%def> <%def name="buildrow(comment, odd=True)"> <tr class="${odd and 'odd' or 'even'}"> <td valign="top"> ${h.link_to( comment.id, h.url_for( controller=u'comment', action='view', id=unicode(comment.id) ) )} </td> <td valign="top"> ${h.link_to( comment.name, h.url_for( controller=u'comment', action='edit', id=unicode(comment.id) ) )} </td> <td valign="top">${comment.created.strftime('%c')}</td> </tr> </%def> % if len(c.paginator): <p>${ c.paginator.pager('$link_first $link_previous $first_item to $last_item of $item_count $link_next $link_last') }</p> <table class="paginator"><tr><th>Comment ID</th><th>Comment Title</th> <th>Posted</th></tr> <% counter=0 %> % for item in c.paginator: ${buildrow(item, counter%2)} <% counter += 1 %> % endfor </table> <p>${ c.paginator.pager('~2~') }</p> % else: <p> No comments have yet been created. <a href="${h.url_for(controller='comment', action='new')}">Add one</a>. </p> % endif At this point, you would be able to perform all the usual actions on comments such as add, edit, and remove if it weren t for the fact they also need a pageid. Now you can start the server and see what you have: $ paster serve --reload development.ini Visit http://localhost:5000/comment/new, and you should see the comment form shown in Figure 14-1.

When querying for data, the database can perform calculations on the data before returning it. You saw such an example earlier in the chapter when COUNT(*) was used to count the number of family members for each lastname. There are a whole range of mathematical functions available in SQL. Some of the most common include SUM, MIN, and MAX, which are used to summarize the values of a column or to get the minimum or maximum value. These functions provide you with a powerful tool. When used in SELECT statements, it is possible to combine these functions with GROUP BY clauses to calculate results based on groups of rows. The results from these calculations can be combined using normal arithmetic operations such as +, -, *, and /. The following statement uses the SUM function, division, and COUNT(*) to calculate the average annual salary for each family: SELECT names.lastname, SUM(salaries.annual)/COUNT(*) AS 'Average', MIN(salaries.annual) AS 'Minimum', MAX(salaries.annual) AS 'Maximum' FROM names LEFT JOIN salaries ON names.id = salaries.id GROUP BY names.lastname Because you do a left join, the family members that do not have an income will be included in the COUNT(*), but not in the functions summarizing and picking out the minimum and maximum values. This means that the minimum salary for those named Doe stays at 900,
