Django创建没有关键字参数的模型实例

Question

In Django, if you want to create a model you can do it as follows:

class SomeModel(models.Model):
    a = models.CharField(max_length=10)
    b = models.CharField(max_length=20)
    c = models.CharField(max_length=30)
    d = models.CharField(max_length=40)
    e = models.CharField(max_length=50)
    f = models.CharField(max_length=60)

Now if you want to create an instance in the shell, you have to do:

> abcdef = SomeModel(a="stuff", b="stuff", c="stuff", d="stuff", e="stuff", f="stuff")

This gets really annoying if you have to keep creating model instances with long property names. Is there a way to simply send the arguments like you would with a normal Python object (as in without having to name the variables and just send the variables in order) ?

Like this:

> abcdef = SomeModel("stuff", "stuff", "stuff", "stuff", "stuff", "stuff")

As you would with a standard Python class in the init function.

Thanks :)

Here is my actual Python model:

class School(models.Model):
    urn = models.CharField(max_length=6)
    name = models.CharField(max_length=100)
    house = models.CharField(max_length=50)
    street = models.CharField(max_length=50)
    county = models.CharField(max_length=50)
    postcode = models.CharField(max_length=8)
    def __unicode__(self):
        return str(
            'URN: ' + self.urn + ', ' +
            'Name: ' + self.name + ', ' +
            'House: ' + self.house + ', ' +
            'Street: ' + self.street + ', ' +
            'County: ' + self.county + ', ' +
            'Postcode: ' + self.postcode + ', '
            )

Answer 1

Have you tried the following code:

obj = SomeModel(None, "a_stuff", "b_stuff", "c_stuff", "d_stuff", "e_stuff", "f_stuff")
obj.save()

Hope these helps.

Answer 2

you can create instance by doing

abcdef = SomeModel()

Since instantiating doesnot touch the database, you can assign values later and then do .save() .
