reason (for example, by throwing a integrityerror exception but not catching it, all the savepoint will be rolled back)
Take a look at the sample code to learn how to play the save point.
@transaction. Atomic () def save_points (self,save=true): user = User.create (' JJ ', ' Inception ', ' JJ ', ' 1234 ') SP1 = Transaction.savepoint () user.name = ' Zheli hui Guadiao, t.t ' user.stripe_id = 4 user.save () if Save: transaction.savepoint_c
transaction can be cut into more "lightweight" transactions, and can be partially rolled back or partially committed.
But be aware that the entire transaction is being rolled back for nothing (for example, because the Integrityerror exception is thrown but not caught, all of the savepoint will be rolled back)
Take a look at the sample code to see how to play the savepoint.

Book Introduction: The author of this book is Wang Han, Qing Wei Long, Wang Zhaoxiang, Blue Sky Works (according to the book is the domestic and Silicon Valley geek). Earlier this year, I rubbed my classmate's Samsung Gear, feeling very shocked: Holy Shit,this is the future ... Then to the IRC lab experience of Microsoft HoloLens and HTC Vive, that immersive experience is really fascinating. In the spirit of reading magazines from the library to borrow this book, to understand the status of

However, it is difficult to learn a network with very strong performance, and its difficulties come from many aspects. Recently, a lot of work has been proposed to improve the performance of the network from the dimension of space, such as embedding multi-scale information in Inception structure, aggregating the characteristics of many different fields to obtain the performance gain, and taking the contextual inf

In the previous CNN we studied, the number of filter, size, pool parameters are to be specified by ourselves, inception can learn parameters to help us automatically choose the best filter,pool combination

In this project, 5 algorithms for experiments are KNN, SVM, BP Neural Network, CNN and Migration Learning. We used the following three ways to experiment KNN, SVM, BP Neural network is what we can learn in school. Powerful and easy to deploy. So the first step, we mainly use Sklearn t
In the April 2015, after the March GDC (game Developers Conference) and F8 (the Facebook Developers Conference), VR (virtual reality) continues to be controversial in the tech world.

popped up, the new queue header is V2 (if the queue is empty at this time, the theorem is true ), therefore, if d [VR] ≤ d [V1] + 1 ≤ d [V2] + 1, the remaining inequality remains true. Therefore, V2 is the topic of the team. To insert a node into the queue, You need to carefully analyze the process BFs. In the 16th rows of BFS, when vertex v joins the queue to become VR + 1, the queue header V1 is actually
