Is it possible Django's administrative panel to make user fields?

Laycee last edited by

Such questions are of particular interest: Is there any way to ask specific fields a particular mask? Is it possible to remove the shooter from the field integer? Is it possible to determine the size of the field and the length of the data input, even if there is a possibility to create a mask, I think it's possible to do it?

Yes, to make changes to the management panel style, perhaps I suggest you look towards the redefinition of admin.py.
In brief, you create and complete the .cs files (in some cases .js) necessary for you to change, and you display references to these files in admin.py, the example of the code:
```
from django.contrib import admin
class MyModelAdmin(admin.ModelAdmin):
    class Media:   
        css = {
             'all': ('/templates/css/admin-extra.css ',)
        }
admin.site.register(MyModel,MyModelAdmin)
```

Try the operation. https://docs.djangoproject.com/es/1.10/ref/models/expressions/#f-expressions :from django.db.models import F listado_facturas = Clasificacion.objects.filter( Q(factura__cliente=1)& Q(factura__trafico__tipo_operacion=1)& Q(factura__trafico__modal=1) & Q(factura__trafico__fecha_cruce=None))\ .order_by().values('factura__valor_factura','factura__id')\ .annotate(total_clasificacion = Sum('total'))\ .filter(factura__valor_factura=F('total_clasificacion')) print(listado_facturas)

There's a working solution:The model creates a method, e.g. get_sitemap_urls:def get_sitemap_urls(self): return [reverse('products:city_product', args=[i.name, self.slug]) for i in self.cities.all()] i.e., actually generate a list based on all, in this case, the cities with which the model relates. And then, sitemap.py Modified method items and locationdef items(self): return list( itertools.chain.from_iterable(( object.get_sitemap_urls() for object in Product.objects.all())) ) def location(self, item): return item Unfortunately, I haven't figured out how to leave the method alive. lastmod

If one/two dates are used in the model, the following characteristics can be simply created:class SomeModel(models.Model): some_date = models.DateField() @property def isoweekday(self): return self.some_date.isoweekday() But if you're more comfortable working with the filter, you need to. https://docs.djangoproject.com/en/3.1/howto/custom-template-tags/ own:from django import template register = template.Library() @register.filter def isoweekday(date): return date.isoweekday()

Your code is wrong, because the difference is always 0, this by these code lines if i == 1: first_price = btc_price #ambas tiene el mismo valor print('the first price is:',first_price) # el valor se resta asi mismo da 0 y toda operacion (* o /) da 0 diferencia = ((btc_price-first_price)/first_price)*100 Suppose btc_price It's 2 let's see what's going on. btc_price = float(2) if i == 1: first_price = btc_price #ambos tienen el valor de 2 print('the first price is:',first_price) diferencia = ((btc_price-first_price)/first_price)*100 #operamos manualmente """ diferencia = ((2-2)/2)*100 diferencia = (0/2)*100 diferencia = 0 * 100 diferencia = 0 """ This causes your condition to never be fulfilled if (diferencia > 0.25)To test your code replace the value of btc and add a print() to see the valuesOjoYou have to be careful with him. continue Since this will cause the cycle to return to the beginning, so it omits what is later, this will cause the times the condition is met to not print the value. From here on it will be omitted, this to have the right result.for i in range(1,minutos_dia): time.sleep(3) btc = {"price":2} btc_price = float(btc["price"]) print( ' ' ) print('the actual value for ADA is:',btc_price) if i == 1: first_price = btc_price print('the first price is:',first_price) print(f'\nlos valores son \nbtc_price={btc_price}\nfirst_price={first_price}\n') diferencia = ((btc_price-first_price)/first_price)*100 print('the % difference is:',diferencia) if (diferencia > 0.25): contador = contador + 1 #continue -> esto omite lo que esta después y vuelve al inicio del ciclo print('Contador:',contador) Departurethe actual value for ADA is: 2.0 the first price is: 2.0 los valores son btc_price=2.0 first_price=2.0 the % difference is: 0.0 Contador: 0 the actual value for ADA is: 2.0 los valores son btc_price=2.0 first_price=2.0 the % difference is: 0.0 Contador: 0 ... #sigue hasta que acaba el ciclo Your question is very confusing, I don't know if you want to keep the value of it. contador or first_price But I tell you if you want to keep the value of first_price because you must declare the variable btc_price outside the cycle and increase as you do with the counter, and if what you want is to maintain and increase the value of contador You're already doing it, the thing is that your condition is never fulfilled for the reasons mentioned above.I did an example to prove that this variable is maintained and increased.Exampleimport random minutos_dia = 2880 contador = 0 for i in range(1,minutos_dia): btc = round(random.random(),3) btc_price = 1 diferencia = btc_price-btc if (diferencia > 0.25): contador += 1 #continue -> esto omite lo que esta después y vuelve al inicio del ciclo print('Contador:',contador) DepartureContador: 1 Contador: 2 Contador: 2 #se imprime dos veces ya que el print() esta fuera de la condición Contador: 3 Contador: 4 Contador: 5 Contador: 6 Contador: 7 Contador: 8 ... #sigue imprimiendo hasta que acabe el ciclo

1 You've got a change in the typewritten 1, you've got a change in the type = input(= get=state) both line and line it up. - Jack_oS yesterday1 You cause a function to get_random_mac_address(), but you don't assign it to the variable. The fact that she's returning random_mac_address doesn't mean that in the next line of "new_mac = random_mac_address" you can operate with that meaning.

I've done it with sesion variables $_SESSION["fails"] So when on the side of the script the credentials are wrong with if / else control when increasing my variable $_SESSION["fails"] and when $_SESSION["fails"] == 3 I make the account lock, it's important to check if $_SESSION["fails"] It's already been set. isset (PHP5 - PHP7) or with ?? de PHP7.4 to avoid being assigned a value.In your code in this part is where I would go: if ($filas > 0) { //Es decir si hay un dato header("location:bienvenido.html"); } else { echo "Error en la autentificación"; $_SESSION['fails'] = $_SESSION['fails'] + 1; if ($_SESSION['fails'] == 3 ) { // Aqui realizas el bloqueo de la cuenta } header("location:index.html"); } Also in your table, you should add something that indicates that the account is blocked, adding a bool field for example "isBlocked", so when you check the fields when you login you may know if it is blocked or not.Already the part of the user who sees everything, you'd have to create roles for your users and just the one who has a role admin you can view the user list and make modifications about any user.

The result of its function is not being saved in any variable (line 5). It should be, for example:resultado = funcao_soma(1,5) print("A soma foi {}".format(resultado)) or if you do not want to use an intermediate variable:print("A soma foi {}".format(funcao_soma(1,5)))

The problem is, you're doing every replace "by shifts." Then first replace 0 by 3. But then you replace the 3 by 0, so you don't get the desired result. In fact, the encryption of the letters will not work properly either, since for example first you change the "a" by "m", but later you change the "m" by "j", so in the end the "aes" remain "jotas" instead of "emes".What you need is a way to make all the changes "at once" in a single replace for that to say. This functionality gives str.translate(). To use it you have to create a "translation sheet" before str.maketrans().Using these things, your code is reduced to a couple of lines:def encriptar(txt): cifra = str.maketrans("abcdefghijklmnopqrstuvwxyz0123456789", "mkwayxhpqfsdjtvrfuoiegcnlb3790285146") return txt.translate(cifra) And you can verify it works:encriptar("1234567890") Get out.7902851463 BonusThe decrypt function is analogous, exchanging the strings used to create the translation table.def desencriptar(txt): cifra = str.maketrans("mkwayxhpqfsdjtvrfuoiegcnlb3790285146", "abcdefghijklmnopqrstuvwxyz0123456789") return txt.translate(cifra)

The decision is very straightforward (directly followed by the text description):max_count = count = 0 # number of positive numbers between negative for n in numbers: if n > 0: # positive: increment count count += 1 max_count = max(max_count, count) elif n < 0: # negative: reset count count = 0 else: # zero: do nothing assert n == 0 print(max_count) The only thinness: if the number is zero, it is neither positive nor negative.

You'll need to write a view inherited from forms.MultiWidgetin which you determine the method __init__with the right types of view, decompress and possibly value_from_datadict♪ We can copy. render of MultiWidget and redesign.Then we'll have to determine our type of field inherited from forms.MultiValueField♪ It's gonna need to indicate the atribut. widgetwith the view you've created, and identify methods. __init__ and compress♪

The simplest way of "going" is to keep it for the right. DataType- a set of parameters, IntegerLet's say they'll be two. min_value and max_value♪And the association between DataSchemeColumn and DataTypeSomething like:class DataType(models.Model): TYPES = ( ('EMAIL', 'Email'), # и т.д. ) name = models.CharField() type = models.CharField(max_length=10, choices=TYPES) class DataTypeParameter(models.Model): name = models.CharField() data_type = models.ForeignKey( DataType, on_delete=models.CASCADE, related_name="parameters") value = models.CharField() # сериализированное значение параметра class DataSchemeColumn(models.Model): name = models.CharField() data_type = models.ForeignKey(DataType, on_delete=models.CASCADE) Inconvenience is that it is necessary to show the parameters manually if they can be different types, or to use other options, how to store different types of values (e.g. several fields of different types of characteristics) string_value♪ int_value etc.).If postgres or mysql are used, these additional parameters may not be stored in a separate collection but in the field of the model itself. DataType type JSONField♪ Then the model DataTypeParameter No need.

You can use the library https://github.com/igorescobar/jQuery-Mask-Plugin , and use https://pt.stackoverflow.com/questions/tagged/regex to check the value of the field. Here’s the example:$(document).ready(function() { var campo = $('.campo'); var alert = $('.erro'); var mascara = "'0.00'"; var fnc = function(v) { // Se o texto do campo tiver o mesmo tamanho // que a variável mascara, incrementa: ,'0.00' e faz o retorno, // caso contrário retorna o valor atual da variável mascara return (v.length === mascara.length) ? mascara += ",'0.00'" : mascara; }; var options = { onKeyPress: function(v, e, f, o) { console.log(v); const reg = /('\d{1}\.\d{2}',?)|(\d+)|(\')/g; let result = true; var test = v.match(reg); if (test) { test.forEach(r => { if (/('\d{1}\.\d{2}',?)/.test(r) === false) { result = false; } }); } // Verifica se o valor da variável 'result' é falso // caso for exibi a mensagem, caso contrário oculta. (result === false) ? alert.show(): alert.hide(); campo.mask(fnc(v), o); } }; campo.mask(mascara, options); });.test { border: 2px solid #ccc; padding: 6px; } .erro { border: 2px solid red; } div.erro { background: #ff7675; border: 0; color: #fff; display: none; font-family: 'Verdana'; font-size: 15px; margin-top: 15px; padding: 12px; }<script src="https://code.jquery.com/jquery-2.2.4.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery.mask/1.14.13/jquery.mask.min.js"></script> <input type="text" class="campo" /> <div class="erro">Dados invalidos</div>Explaining:'Allows simple quotes♪Allows only one type after quotation..Allows a point.♪Allows only two digits after the point.?Allows an optional comma after quotation.|(\d+)|(')Recovers the rest of the value that the user entered, to check this filled correctly.
