Doesn't the save code check that it's not already in a transaction before starting a transaction? |

```->save($entity, ['atomic' => false]);``` |

is the term that says that it shouldn't have a transaction |

```'atomic' => false``` |

I got this `use` but I am not getting how can I convert my code to achieve transactions as you also said `->save()` already has its own `commit` |
| # |
Jun 21st 2021, 18:10 |
kevin.pfeifer |
so everything you expect inside your function needs to be passed via the `use` at the end of the first line, otherwise you don't have access to these variables |
| # |

basically ```$result = 0; $one = function() { var_dump($result); }; $two = function() use ($result) { var_dump($result); }; $three = function() use (and$result) { var_dump($result); }; $result++; $one(); // outputs NULL: $result is not in scope $two(); // outputs int(0): $result was copied $three(); // outputs int(1)``` |

they are called php anonymous functions https://www.php.net/manual/en/functions.anonymous.php |
| # |
Jun 21st 2021, 18:07 |
alamnaryab |
in your second last message you said "need to pass inside via `use`" |
| # |
Jun 21st 2021, 18:07 |
kevin.pfeifer |
yes, thats why you would have to wrap all those ->saveOrFail() inside the ->transactional(); |
| # |
Jun 21st 2021, 18:04 |
alamnaryab |
`->saveOrFail()` will also revert that entity only not all those which saved successfully before it in same process |
| # |
Jun 21st 2021, 18:01 |
kevin.pfeifer |
instead of the normal ->save() function which only returns the $entity with the errors |
| # |
Jun 21st 2021, 18:00 |
kevin.pfeifer |
there is also a `->saveOrFail($entity)` function which throws an exception if something couldn't be saved. |
| # |
Jun 21st 2021, 17:50 |
kevin.pfeifer |
well everything from "outside" the transactional function you need to pass inside via the `use` at the end Other then that it should be pretty much the same from your current logic |
| # |
Jun 21st 2021, 17:47 |
alamnaryab |
But I think I can not use `->transactional()` also because all these entities are not for same model, also each entity properties has foreign keys from previously saved record. and there are some conditional properties. |
| # |
Jun 21st 2021, 17:36 |
kevin.pfeifer |
it seems that usually every `->save($entity)` call has its own transaction, thats why you can't rollback them now |

docs for cakephp 4 https://book.cakephp.org/4/en/orm/saving-data.html#converting-multiple-records But this `->transactional()` function is still present in cake 4 so you could try that I guess :man-shrugging: |
| # |
Jun 21st 2021, 17:35 |
kevin.pfeifer |
looking at https://book.cakephp.org/3/en/orm/saving-data.html#converting-multiple-records there is a `->transactional()` function you could use to wrap all those saves in one transaction ```$this->Model1->getConnection()->transactional(function () use ($articles, $entities) { foreach ($entities as $entity) { $articles->save($entity, ['atomic' => false]); } });``` But this part has been removed from the |

Model2'); } if(!$this->Model9->save(...) ){ throw exception('Could not save Model9'); } $datasource->commit(); }catch(Exception $ex){ $datasource->rollback(); $this->Flash->error($ex->getMessage(). ' Line:'.$ex->getLine()); }``` |
| # |
Jun 21st 2021, 17:23 |
alamnaryab |
in cakephp2 I am having something like this ```$datasource = $this->Model1->getDataSource(); $datasource->begin(); try{ if(!$this->Model1->save(...) ){ throw exception('Could not save Model1'); } if(!$this->Model2->save(...) ){ throw exception('Could not save Model2'); } $this->Model3->id = $this->Model2->id; /////insert statement if(!$this->Model3->save(...) ){ throw exception('Could not save |

kevin.pfeifer |
and you get false back from `$this->Tags->save()` if it didn't save |
| # |
Jun 21st 2021, 17:19 |
kevin.pfeifer |
well `$this->Tags->save()` will not save if there are errors in the entity and therefore you don't have to manually rollback. You have multiple events you can hook into in the `src/Table/MyTable.php` https://book.cakephp.org/3/en/orm/table-objects.html#lifecycle-callbacks But maybe I don't understand your usecase. |

If by forwarding you mean you're just redirecting a user, then it should pick up the session where it left, given that the session cookie is still valid. |
| # |
Jun 21st 2021, 16:28 |
ndm |
Yes, very likely that it doesn't send the session cookie. Depending on what that external thing is, it might not even have that cookie. |
| # |

I wondered if the third party don’t send the cookie if the request wouldn’t contain the session? Is that a thing? As it’s `$this ->getRequest()->getSession()` |
| # |

If something external posts to my application, will the request not include the sesssion? I am writing data before forwarding a user off, and when they return I want to match stuff with the session from before they left, but it’s not preset |

Not with regards to preventing absolute URLs from slipping in, no, `getLoginRedirect()` will prevent that just fine, it just needs to be actually used :) |

so this isn’t an issue with the authentication plugin? I don’t have a “pure” authentication app ready to test it |
| # |

You may want to open an issue with cakedc/users so that they can possibly fix it. |
| # |
Jun 21st 2021, 15:35 |
kevin.pfeifer |
but isn't that exactly what is being discussed here? https://github.com/cakephp/authentication/issues/450 |
| # |
Jun 21st 2021, 15:32 |
kevin.pfeifer |
I can confirm the external redirect from the `redirect_to=<url_encoded-URL>` param when using cakedc/users which is based on the authentication plugin |

we jumped on the Authentication middleware with version 1.x ... I guess we forgot to change this part for 2.x ... I feel a bit stupid now. |
| # |
Jun 21st 2021, 14:31 |
ndm |
`getLoginRedirect()` was introduced with some early 1.x version I think, so at some point the docs were different. |
| # |
Jun 21st 2021, 14:25 |

we actually used that page to build what we have now... has this been changed? or did we just mess things up at some point? |

where do I find docs to do this properly ... or in other words, where do I find docs to read how this should be fixed? |

a.vanniel |
```$redirect = $this->request->getQuery('redirect', [ 'controller' => 'Pages', 'action' => 'display', 'home' ]);``` I think this must be old and has not been updated at some point... |
