[Drupal] Sort views according to a field term name alphabetical order

If you try to sort a view according to a vocabulary field, it will be sorted by terms tids and not by terms names. Views only sees the data as a bunch of tids. Because of this, allowing the sorting on that column would produce some unintended results.

Instead, you need to create a relationship. Once you've created your Content Taxonomy field, go to your View and add a relationship. Under the "Content" selections, pick the Content Taxonomy field you want sortable. Save that, and now you need to create a new field. Select "Taxonomy: Term" as your field and continue. In the new options and in the "Relationship" dropdown, select the relationship that you just created, make any other changes you'd like, then click the "Update" button. At this point, you should be able to click your "Style: Table" gear and be able to sort by term name. Just remember to save the changes to the View itself! =)
