Hello,
I am trying to write my first web application{, in django}. And I'm getting
a little bit stuck on the following point:
I want an application for classify my Wine, which could be red or white.
Here is the point where I can't manage to
get on (maybe its not the good way to design a database).
$ less wine/models.py
[...]
class Color(models.Model):
class Meta:
abstract = True
tone = models.CharField(len = 32, choices = SOMETHING)
class RedColor(Color):
R_COLORS = (("ligth red", "light red"),
("red", "red"),
("dark red", "dark red"))
# tell Color() that the SOMETHING must be equals to R_COLORS
class WhiteColor(Color):
W_COLORS = (("light white", "light white"),
("white", "white"),
("dark white", "dark white"))
# tell Color() that the SOMETHING must be equals to W_COLORS
In other words I want to have the color class abtract for holding the field
"tone" because this field is shared between both wine with white and red
color. I also want that, regarding the colors of the wine the user is only
allowed to perform some slightly change on the colors tones.
My problems are :
1. I don't know how to translate this into correct Python/Django
2. I don't know if its a good idea to build the database regarding the
value to be stored into
If someone can give me some direction, it will be great !
See u !
PS: I will have the same problem for different tables within the
application (the light reflection, the grappe variety...)
PPS: I will certainly have the same problems when I will write the same
kind of application for classifying beers.
