<https://stackoverflow.com/questions/44457374/how-should-i-do-this-in-django#>
I was thinking about making a Hostel Allocation Web application. It has
models, Student, Room, Hostel. What I want is to create a function that
allocates students after each year. For that, I thought in the student view
each student after completing his four years of stay can click on vacate
hostel after completing his degree, and for others, I want to create
something that allocates them, Now there are certain constraints, there are
Undergraduate students with degree period 4 years and each year has access
to different types of rooms, First-year triple sharing, second and
third-year double sharing and fourth-year single rooms. Also, a Hostel has
Ph.D. students as well but their stay period is not defined.
So, what I was thinking is that First years should be allotted by uploading
a CSV file and I have made that part, So the next part is to allot
subsequent years based on their preferences, So how could I make something
like this in Django that allows them to make it based on their preference,
I was thinking each student would be given a unique token, and while
filling for rooms one student can do for a room, and that token needs to be
entered. Is this the right way or should I do something else. I am a newbie
please suggest me a good way to do this.
models.py
class Student(models.Model):
name = models.CharField(max_length = 40,help_text = "Name of the student")
entry_number = models.CharField(max_length = 11,help_text = "Entry Number
of a student")
hostel_name = models.ForeignKey('Hostel', on_delete = models.SET_NULL,null
= True)
room = models.ForeignKey('Room',on_delete = models.SET_NULL,null = True)
CHOICES = (
('m','Male'),
('f','Female'),
('e','Engaged'),
)
gender = models.CharField(max_length=1,choices=CHOICES)
def __str__(self):
return '%s, %s' % (self.name,self.entry_number)
def get_absolute_url(self):
return reverse('student-detail',args=[str(self.id)])
class Meta:
verbose_name="Student Record"
class Hostel(models.Model):
name= models.CharField(max_length= 15)
locality= models.URLField(max_length= 200, blank= True,
default='',help_text='Google maps URL of the hostel')
total_rooms= models.PositiveSmallIntegerField(null=True, blank =True)
CHOICES = (
('m', 'Male'),
('f', 'Female'),
('e', 'Engaged'),
)
gender = models.CharField(max_length=1, choices=CHOICES,
verbose_name=_('Type of Hostel'), help_text='Either Boys/Girls or Married
students Hostel')
def __str__(self):
return self.name
def get_absolute_url(self):
return reverse('hostel-detail',args=[str(self.id)])
class Meta:

class Room(models.Model):
hostel= models.ForeignKey(Hostel, on_delete=models.CASCADE)

wing= models.CharField(max_length = 1, blank=True)
comment= models.CharField(max_length = 100,blank=True, default = "comment
here")
room_capacity =
models.PositiveSmallIntegerField(validators=[MaxValueValidator(3),])
room_accomodation= models.PositiveSmallIntegerField()
