sqlalchemy / examples / association /


Examples illustrating the usage of the "association object" pattern,
where an intermediary class mediates the relationship between two
classes that are associated in a many-to-many pattern.

This directory includes the following examples:

* - illustrate a many-to-many relationship between an
  "Order" and a collection of "Item" objects, associating a purchase price
  with each via an association object called "OrderItem"
* - same example as basic_association, adding in
  usage of :mod:`sqlalchemy.ext.associationproxy` to make explicit references
  to "OrderItem" optional.
* - an advanced association proxy example which
  illustrates nesting of association proxies to produce multi-level Python
  collections, in this case a dictionary with string keys and sets of integers
  as values, which conceal the underlying mapped classes.

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.

Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
