Drupal 7 Fields and Friends

Here's a quick little list of fields related moudules that have come in very handy lately:

http://drupal.org/project/field_collection.  This module lets you create a field that is a collection of fields.  For example if you need to create a route that contains an arbitrary number of paths, you would create a field collection that contains a path field.  The user can then add as many paths to the route as they need.  Drag and drop re-ordering is supported as well.

http://drupal.org/project/filefield_sources.  This module simply makes it easy to re-use already uploaded files.

http://drupal.org/project/references.  The sucessor to node reference this module lets you reference nodes and users in a field.

There are also a few modules I have not tried but might come in handy:

http://drupal.org/project/viewreference.  This lets you reference a view from within a field on a node, just like node reference.

http://drupal.org/project/field_group.  This lets you put fields into groups that then appear as "tabs" on the node edit form.
