The title

This example shows how to create a simple file library. It demonstrates batching and sorting. You can click on the column names to sort the files. If you click twice on a column then the files are sorted in reverse order. If you upload more than eight files, then the results will be split up over more than one page. This is called batching.

The files are located in the Files folder. The getFiles script returns a sorted list of files. The getLink and getSize scripts do small formatting tasks to build hyperlinks and format file sizes. The batching is done in the index_html template. The template also makes use of the test function to assign different CSS classes to elements depending on conditions. This is how the sorted column name is bolded and alternate table rows are made gray.

There are no files currently available.

Upload a File

You can add a file to the library by uploading it from your local computer. The addFile script accepts the file upload and creates a new file object in the Files folder. It then returns this page with a confirmation message. For demonstration purposes, only 10 files of no larger than 2Kbytes may be uploaded.

Adding files is protected by the "Add Documents, Images and Files" permission. If you want anonymous users to upload files, you could visit the "Security" tab of the addFile script, and give it the "Manager" proxy role.

breadcrumbs navigation

The title

This example shows how to create simple automatic navigation devices. Take a look at the Navigation folder to see how it was built. The automatically created links on this page allow you to traverse a collection of folders and sub-folders.

Current Folder: Folder ID

Parent Links

The links you see across the top of the page are called breadcrumbs. They show you where you are in the site and let you navigate up the site tree. They are created with a Python-based script, breadcrumbs.py.

Child Links

These automatic links allow you to navigate deeper into the site. These links are created with a Python expression in a Page Template. You could also use a Python-based Script to create the links.

You could customize these links to only show certain sub-folders, rather than listing all sub-folders.

There are no sub-folders here.

Sibling Links

This navigation device allows you to go to sibling folders. A sibling folder is one that is in the same parent as the current folder. The list of siblings is generated by the siblings.py script.

There are no sibling folders here.

The contents of the cart are stored in a session. The session variable items keeps track of the item ids and quantities of items in your shopping cart. The currentItems script uses this information to retrieve records describing the items in the shopping card. The deleteItems script removes items from the shopping cart.

This example shows how to create a simple guest book.

The guest book stores its entries as file objects in the Entries folder. This page displays the entries by looping over a sorted list of entries and displaying each one. The list of entries is created by the getEntries script. The formatEntry script formats each guest book entry. To remove an entry, remove its file from the Entries folder. An alternate version of this application could use ZSQL Methods to store guest book entries in a relational database.

The addEntry.html template provides a form that allows you to sign the guest book. The form is processed by the addEntry script. The addEntry script stores the entry as a file. Adding files is protected by the "Add Documents, Images and Files" permission; if you want anonymous users to sign the guest book, you could visit the 'Security' tab of the addEntry script, and give it the "Manager" proxy role.
