While users typically obey the rules and use your site the way it s expected to be used, any reasonable developer prepares for those who don t Django takes a number of precautions to protect against unauthorized access to things like the administration interface and provides decorators to restrict access to application views, but there are still more subtle things to take into account For instance, the sessions framework needs to worry about users altering the session ID in an attempt to hijack another user s session These types of things don t fall under authentication or permissions themselves, but rather a user is attempting to circumvent these usual protections It s important to identify when this occurs, so it can be dealt with appropriately To identify these across the board, Django provides a exception that can be used any time something like this happens.

A transaction is a set of operations that must either succeed or fail as a unit. The goal of a transaction is to ensure that data is always in a valid, consistent state. For example, consider a transaction that transfers $1,000 from account A to account B. Clearly there are two operations: It should deduct $1,000 from account A. It should add $1,000 to account B.

Suppose that an application successfully completes step 1, but, because of some error, step 2 fails This leads to an inconsistent data, because the total amount of money in the system is no longer accurate A full $1,000 has gone missing Transactions help avoid these types of problems by ensuring that changes are committed to a data source only if all the steps are successful So, in this example, if step 2 fails, then the changes made by step 1 will not be committed to the database This ensures that the system stays in one of its two valid states the initial state (with no money transferred) and the final state (with money debited from one account and credited to another) Transactions are characterized by four properties popularly called ACID properties.

ACID is an acronym that represents the following concepts: Atomic: All steps in the transaction should succeed or fail together Unless all the steps from a transaction complete, a transaction is not considered complete Consistent: The transaction takes the underlying database from one stable state to another Isolated: Every transaction is an independent entity One transaction should not affect any other transaction running at the same time Durable: Changes that occur during the transaction are permanently stored on some media, typically a hard disk, before the transaction is declared successful Logs are maintained so that the database can be restored to a valid state even if a hardware or network failure occurs Note that even though these are ideal characteristics of a transaction, they aren t always absolutely attainable.

In many situations, this is thrown and caught in the same application but is provided so that it s possible to reach into the application and use just the portion that raises the exception In other cases, it s left exposed to other applications to handle in whatever way makes the most sense The signed cookies application from 7 is a good example of where suspicious activity can be easily identified and handled If a cookie comes in without a valid signature, it s clear that something fishy is going on and the signature validation code raises a to signify it Since it s designed to work as a hands-free middleware, it also provides code to catch this exception and perform a more useful function by removing the offending cookie from the request before it reaches the view.

One problem is that in order to ensure isolation, the RDBMS needs to lock data so that other users can t access it while the transaction is in progress The more locks you use, and the coarser these locks are, the greater the chance that a user won t be able to perform another task while the transactions are underway In other words, there s often a trade-off between user concurrency and isolation..
