You add a context processor that takes place in the bootstrap process. For instance I needed access to two forms in all my templates and views. Because I do login and signup as a modal in my base template.

It allows you to do some really nice things without repeating yourself

Example in settings.py.

TEMPLATES = [
{
"BACKEND": "django.template.backends.django.DjangoTemplates",
"DIRS": [os.path.join(PROJECT_ROOT, "templates")],
"OPTIONS": {
"debug": DEBUG,
"context_processors": context_processors,
"loaders": loaders,
"string_if_invalid": '<< MISSING VARIABLE "%s" >>' if DEBUG else "",
},
}
]

@jyoost I'll have a look. Thanks! :)

I don't think it will work for my use-case as I don't use templates.

Hey, I've been looking into generic foreign keys, and I've been wondering if you can limit the field type choices for them

For example if you have a model like this

class Message(models.Model):
    message = models.CharField(max_length=100)

    source_type = models.ForeignKey(ContentType, null=True, on_delete=models.SET_NULL,)
    source_id = models.PositiveIntegerField(null=True)
    source = GenericForeignKey('source_type', 'source_id', )

How can you limit the foreign key to be for only two or three types of models ?

I've thought of adding a validator to the type field but I have a feeling there's a better way

Is this the right place to ask questions, if one seached the Internet for a couple of hours?

Max Wittig

@max-wittig

if so. Anybody knows how to do

SELECT id, name, something FROM something

without using values and by using database operations, when the model is more complicated?

Example:

class SomeComplicatedModel(models.Model):
    id = models.IntegerField(primary_key=True)
    name = models.CharField(max_length=2000)
    description = models.CharField(max_length=2000, null=True, blank=True)
    members = models.ManyToManyField("GitlabUser")
    url = models.URLField(null=True, blank=True)
    namespace = models.CharField(max_length=2000)
    KIND_CHOICES = [(GROUP_TYPE, GROUP_TYPE), (USER_TYPE, USER_TYPE)]
    kind = models.CharField(choices=KIND_CHOICES, max_length=20)
    update_uuid = models.UUIDField()

    def __str__(self):
        return f"{self.id} | {self.namespace}"

How do I access only kind from using values?

This is complicated as values is only accepting positional arguments. So I might be able to access id and name using

SomeComplicatedModel.objects.all().values("id", "name")

but if I don't need name, things get complicated

Thanks for any help! Hope this is the right channel

Hey

i need help with some project which i was unable to run as it shows Using the URLconf defined in djangosite.urls, Django tried these URL patterns, in this order: --> The current URL, , didn't match any of these.

can someone help me

matrixbot

@matrixbot

Ajira Hi sundeep, what is the url you tried to reach and what are the patterns in your djangosite/urls.py file ?

matrixbot

@matrixbot

defiance There is (or used to be) a legit reason to start your urlpatterns with an empty string; I can't remember what that is or if it's still relevant; anyone?
