问题 I want to make a copy from my blog object and its comment. i write some code and it works for blog instance but does not copy its comments. This is my model: class Blog(models.Model): title = models.CharField(max_length=250) body = models.TextField() author = models.ForeignKey(Author, on_delete=models.CASCADE) date_created = models.DateTimeField(auto_now_add=True) class Comment(models.Model): blog = models.ForeignKey(Blog, on_delete=models.CASCADE) text = models.CharField(max_length=500) and

问题 I am sorry if this question seems pretty straight forward. But reading the Keras save and restore help page : https://www.tensorflow.org/beta/tutorials/keras/save_and_restore_models I do not understand how to use the "ModelCheckpoint" for saving during training. The help file mentions it should give 3 files, I see only one, MODEL.ckpt. Here is my code: checkpoint_dir = FolderName + "/tmp/model.ckpt" cp_callback = k.callbacks.ModelCheckpoint(checkpoint_dir,verbose=1,save_weights_only=True)

问题 Spring Boot 2.4.0 , DB is MySql 8 . Data is fetched every 15 seconds from remote with REST and storing it to MySql DB with saveAll() . Which call the save() method for all the given entities. All data has set ID. And I am expecting that if there is no such id at DB - it will be inserted . If such ID is already presented at DB - it will be updated . Here is snipped from the console: Hibernate: insert into iot_entity (controller_ref, description, device_id, device_ref, entity_type_ref, hw

问题 Scene support and multiple windows in iOS 13 have complicated the question of when to save data. A scene delegate's sceneDidEnterBackground might seem like a pretty good place, but there are times when it won't be sufficient: If your scene was frontmost and the user goes to the app switcher and terminates your app, you'll get sceneDidDisconnect and applicationWillTerminate , not sceneDidEnterBackground . If the user switches off the device while your app is frontmost, you'll get

问题 FUNCTIONAL PORTION: The code below saves 2 tabs from an xlsm file to a new xlsx file. the file stays open for editing. ERROR: The xlsm tab has a trigger in the sheet code. That trigger is invalid and causes an error as soon as anything is entered in the xlsx sheet. DESIRED OUTPUT: no error generated when editing the new file FAILED FIX ATTEMPT: I tried to use Scripting to delete the macros but the brand new sheet doesn't give access to its code. I might have done that wrong... Sub seedPro()

问题 Disclaimer : Many of you pointed to a duplicated post, I was aware of it but I believe it's not a fair duplicate as some way of saving/loading might be different for data frames and lists. For instance the packages fst and feather work on data frames but not on lists. My question is specific to lists . I have a ~50M element list and I'd like to save it to a file to share it among different R sessions. I know the native ways of saving in R ( save , save.image , saveRDS ). My point was : would

问题 When I first click the button it doesn't work. On my second click it downloads 1 picture. My 3rd click it downloads 2 pictures. On my 4th click it downloads 3 pictures. So 1-0, 2-1, 3-2, 4-3. They are also downloaded immediately, it doesn't ask where to save. js: function xyz(){ const text =canvas.api.getCanvasAsImage(); const download = document.getElementById('download'); download.addEventListener('click', function(e) { var link = document.createElement('a'); link.download = 'download.png';
