17. Relationships Because of the relationship, you know some things about the other person.

18. What is a relationships? Content User Author’s Name Content type (taxonomy) Image • Menu category • Starters • Appetizers

19. Why? You want to maintain a single copy / instance of your data. Your web site reference the single copy / instance of your data. If you change the data, it is changed through out the web site.

20. Relationships Author / user create a content node An image is associated with a content node A taxonomy term associated with a content node Another entity associated with a content node

21. How do you create arelationship? Kind of like setting up a taxonomy entry. Remember, an entity references another entity! Setup a content type of Waiter / staff Setup a content type of menu dish On the Customer Order, we will “connect” the customer order to both the Waiter / staff and menu dish content types.

26. Univ. of Hard Knocks Suggestions for Views • Include node type in field name • Easily find field in views list of fields.

27. Relationship Examples • Display an customer order (Example 8) • Restaurant customer order relationships: • Waiter / staff • Item order reference menu dish

28. Relationship / SQL View • INNER JOIN: • Returns all rows when there is at least one match in BOTH tables. • Require relationship = Y • LEFT JOIN: • Return all rows from the left table, and the matched rows from the right table. • Require relationship = N

29. ViewsAdd relationships • Views – Add relationship (Example 8) • Referenced – Read entity referenced from source • View is based upon Customer Order and reading Staff, and Dish information • Referencing – Read source from entity reference • View is based upon Staff and reading Customer Order information.

30. Download a table into a CSV file modules: views_data_export The module view data export will allow you to download your table view into a comma separated value (CSV) file.

31. Download a table into a CSV file (Example 9) Data export is exposed on your view

32. Download a table into a CSV file (Example 10) Choose “Data Export” from the +Add in views Notice your Format is CSV File

33. Download a table into a CSV file • You can put replacement patterns in the file name • Setting • The text “by deselection this, the xml file…” is a bit misleading. • Need to check “Provide as file” if you want a download file!

34. Download a table into a CSV file • Make sure you specify: • A path • I used <view_path>_dnld • Attach to – The view to attach the download. • Batch export – Yes if big download • Pager = Display all items

35. Views conditionals module: views_conditional You want to check some condition before you decided to the field should be displayed. In my case, I check a person’s role before decide if they have the permissions to see a specific field. Example

36. UHK Suggestions for Views • Name content types in singular • Names views in plural • If using multiple views: • “All displays” vs “this page” • Structure -> Views -> Settings • Show the SQL query • Make input required BEFORE views runs.

37. UHK Suggestions for Views • Page views with same path. • Bad – only one view will appear in the menu • Good – if the different views have different role permission, you can have multiple views under one menu item – and role appropriate view will appear. • With views aggregation – do not sort the data. Let the aggregation do it. • Don’t forget to put in No Results message in your view.
