How do you make one request for all related objects?

class Модель_1(models.Model): 
    поле = models.IntegerField()


class Модель_2(models.Model):
    модель_1 = models.ForeignKey(Модель_1, related_name="модели_1")


модели_1 = Модель_1.objects.filter(поле="значение")
```
I've chosen models, or part of the models.
Now, as a separate request, it's just one request and without prefetch_related, to select all the Models2 that are linked to the models already selected.
It's just a thought to try to use the values... for the sample. You can't download the bound tables.

ids = модели_1.values_list('id', flat=True)

#или, если queryset уже выбран из базы
ids = [o.id for o in модели_1]

Модель_2.objects.filter(модель_1_id__in=ids)

You can do one job, you don't need a mass.$("input[type=checkbox]:not(:first)").each(function() { $(this).attr({ name: 'checkMess[]', id: $(this).attr('value'), }); });<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <input type="checkbox" value="first"> <input type="checkbox" value="second"> <input type="checkbox" value="third"> <input type="checkbox" value="fourth">

When you have a "one to one" relationship, jpa by default considers that the fetchType is "eager", this means that the daughter entity is loaded into the parent entity by default. To define your relationship well, you have to define what the parent entity of the relationship is and what the daughter is. In the case of the parent entity is where you perform the mappedBy and the cascade within your @OneToOne And in this cascade is where your mistake is. You're putting it in both entities (and I intuit by the code that your relationship is not bidirectional because you're treating your LevelSensor entity like the parent). In an entity you are declaring cascade=CascadeType.ALL and the other cascade=CascadeType.PERSIST the attribute Cascade what it does is to tell jpa how to behave in the relationship between the parent entity and the daughter entity, therefore, by telling him that the cascadeType is persists implies that only "use" the relationship between the two entities at the time of persisting in database and not in the rest of operations. The ideal thing is to use all in this entity to consider that attribute as a daughter entity in the rest of operations as well, you can find more info on this property here: https://docs.oracle.com/cd/E19798-01/821-1841/bnbqm/index.html With this done, I will tell you that hibernate knows perfectly to treat your entity daughter and (just having that attribute filled with an existing id) jpa knows perfectly how to map that relationship and will give you the corresponding exception in case you try to violate it.

When you see the source code of the site you mention, you can see that to generate the table you make a request to a URL that returns the data in CSV format.I show you how to get it with javascript. It's not Python, but the procedure must be the same:const getData = async () => { // Se hace una petición a la URL que contiene los datos let response = await fetch('https://airtmrates.com/rates'); // Se toma la respuesta y se convierte a texto plano let text = await response.text(); // Se genera un array dividiendo el texto en cada salto de linea let lines = text.split('\n'); // Se itera sobre el array for ( let line of lines ) { // Se busca la linea que inicie con "ARS," y si se encuentra, // se convierte la linea en array dividiendola por comas if ( line.startsWith('ARS,') ) return line.split(','); } return []; }; (async () => { let data = await getData(); console.log(data); })();

If not https://django-debug-toolbar.readthedocs.io/en/stable/ or custom middleware is the most appropriate solution to measure the processing time of the request in the context of ListViewin my view, it is redefined dispatch inside ListView:def dispatch(self, *args, **kwargs): start_time = time.time() response = super().dispatch(*args, **kwargs) total = (time.time() - start_time) * 1000 # print(total) # or # response['X-total-time'] = total return response

/users/18030/jony , the OBD won't be able to separate the data into two sets (except two requests). Don't be afraid of the extra cycle, it's not likely to eat more time than the time spent on data transmission (not finding) from the violin to the OBD and vice versa.

An ordinary solution to your problem would be to declare class. ContentViewer Total T:public partial class ContentViewer<T> : UserControl { public ObservableCollection<T> ItemsCollection { ... In your case, however, the problem is that it is impossible in the XAML to declare generic control is only supported by the controllers. specific Like.That's why your class will have to be broken. For example:public partial class ContentViewerBase : UserControl { public ContentViewerBase() { InitializeComponent(); MainGrid.DataContext = this; } } (and the same XAML).In the XAML, you can already be tied to collections, because Binding has a late contact. Collect on top:class ContentViewerGeneric<T> : ContentViewerBase { #region DP ItemsCollections public ObservableCollection<T> ItemsCollection { get { return (ObservableCollection<T>)GetValue(ItemsCollectionProperty); } set { SetValue(ItemsCollectionProperty, value); } } public static readonly DependencyProperty ItemsCollectionProperty = DependencyProperty.Register ( "ItemsCollection", typeof(ObservableCollection<T>), typeof(ContentViewerGeneric<T>)); #endregion } class ContentViewerOfDouble : ContentViewerGeneric<double> { } class ContentViewerOfString : ContentViewerGeneric<string> { } etc.Only " specific " classes such as ContentViewerOfDoubleof course.<local:ContentViewerOfDouble ItemsCollection="..."/>

nginx-app.confSince STATIC_ROOT was not set, even if it works in the virtualenv test environmentThere was a step-by-step error in docker deployment environmentFor the deployment environment, STATIC_ROOT did not understand that collectstatic needed to specify a directory to collect static filesJust because the探 of the Django admin page does not apply, you need to find the causeI think it was difficult to understand in my writing, but I thank you very much for your understanding.

What you need is a type field. FileFieldalready FilePathField It's like a CharField but with some extra methods to find files in a "fuzzy" way.What you should do is declare in your model a type field FileField and in the parameter upload_to place the route relative to the folder to which you want your files to be uploaded.Remember to have your file well configured settings.py with variables MEDIA_ROOT and MEDIA_URL since the files will be uploaded to the folder MEDIA_ROOT/ruta_relativa that you put in your model.More info here https://docs.djangoproject.com/en/2.2/ref/models/fields/#filefield .

What is better is always complicated to assert without a specific context.People think that creating connections costs expensive and that there will be a complicated process. At least that's what I imagine, I'm not in their head. I know that many use this premise, but it may be that they are only copying what they saw wrong there.The fact is that the connection object is a pool, it delivers you a connection according to your need and knows how to manage the connections, and it is a well-thought and developed object by people who understand how to do. Everything works perfectly, with performance in a simplified way.It is even possible to create a simple abstraction to simplify something specific, but to create a Singleton, or a replacement for the connection, as I see in almost all the codes that the staff put here, is absurd, is a antipattern. It is a person who little or nothing understands the subject trying to create something certainly worse for little or no gain.So the two cases presented seem to be wrong. Of course, I didn't see that class. AcessoBancobut almost everyone does wrong.These reported problems probably occur because it is implementing wrong. And the right thing is not to implement any of this. It begins to create new problems to solve the problems that should never exist. If it was necessary an abstraction of this type for any application the .NET would provide. Never implement anything that cannot justify with property.I believe that the problem occurs because people try to create design patterns without even understanding what problem it is solving, this includes DAO or repository, in general it is quite complicated to do right, and almost always does not give the benefit that the person thinks will give, it is just doing what "ever" is doing, without understanding how to do.By the comment it seems not to make sense to have a Singleton, after all it has different connections, it is plural and not singular.

You're trying to tie the user.Useralthough it should be tied to the profil (UserProfile)P. S.:In general, this is not a very good architectural solution, so I suggest you link the post model directly to the user model.Example:... class Post(models.Model): ... current_user = models.ForeignKey(User, ...) After that, the presentation should work without error.

let ascii = {} for( let i = 48; i <= 122; i++ ){ ascii[ i ] = String.fromCharCode(i); } console.log( ascii );And if there's already been such a mass, you can redo it like that:let ascii = []; for (let i = 48; i <= 122; i++) { let ascii_el = String.fromCharCode(i); ascii.push({i, ascii_el}); } let obj = {}; for( let i = 0; i < ascii.length; i++ ){ obj[ ascii[ i ].i ] = ascii[ i ].ascii_el; } console.log( obj );
