Re: how to manage range of hours in models and forms in django1.4

If the days have to be hardcoded (I imagine you have a row/field for each day), then you could use a hardcoded string for the day (not editable nor related to your model), and provide two Time fields. Using Time gives you advantages:

 

* You can use python's DateTime module to calculate the hours

* You can more easily use a funky date/time style widget if you ever need it

* You will avoid making mistakes trying to calculate the hours manually

* You can validate the form data using python's date/time module

 

If you're really open to suggestions (just thinking outside the box, and possible outside of the scope), but you could use a separate table to record all hours recorded rather than just counting the hours as they're entered.

Hi Jon

Yes it is the count of the hours.They will enter in the following manner "-

Monday : 0900-1800, Tuesday and so on ... This will be entered by the user who is filling the form.

Now the text Moday(weekdays can be hardcoded but i personally don't want.)
Now if you see this is a simple CharField where the user enters details for the number_of_hours.
So i want to know what type of model field should i create CharField or Time Field.

If i   go for CharField it will simply save the details like 0900-1800. So if i need to know how many hours that particular person is available for work then how will subtract that from CharField.

So i need help to know what exactly the field i should create such that it satisfies the template look and backened queries also.

I understand that institue_hours_of_operation is a count of the hours the user has worked, is that correct? If so, I suppose you just need to count the hours with each form submition and add that to the current institue_hours_of_operation value. You can do that logic in a few places. In class-based views, I tend to put it in form_valid().

 

Apologies if I've misunderstood :)

Hi

I am developing an event app which has users who publish events , other users also.
Now users have their profile info for which i have made a very common UserProfile Model with all the necessary details in it.

I have a requirement where in UserProfile model i need to display a field institue_hours_of_operation( no. of hours that an institute works)


class UserProfile(models.Model):
    user = models.ForeignKey(User, blank=True, null=True, unique=True)
    first_name = models.CharField(max_length=30, blank=True)
    last_name = models.CharField(max_length=30, blank=True)
    gender = models.CharField(max_length=1, choices=GENDER_CHOICES, blank=True)
    birth_date = models.DateField(auto_now_add=True)
    street_address = models.CharField(max_length=75, blank=True)
    city = models.CharField(max_length=30, blank=True)
    zip_code = models.IntegerField(max_length=7, blank=True, null=True)
    country = models.CharField(max_length=30, blank=True)
    mobile = models.CharField(max_length=15, blank=True)
    home_phone = models.CharField(max_length=15, blank=True)
    primary_email = models.EmailField(max_length=60, blank=True)
    secondary_email = models.EmailField(max_length=60, blank=True)
    institution_name = models.CharField(max_length=100,blank=True,null=True)
    institution_website = models.CharField(max_length=100,blank=True,null=True)


# Field to be added

It will be displayed in html like this

Insitutue hour of operation :       Monday  9.00 - 17.00 (Monday will be hardcoded,Time will be filled by user)
                                              Tuesday 9.00 - 17.00 (Monday will be hardcoded,Time will be filled by user)

                                               and so on

# Note the weekdays like monday,  tuesday they are all hardcoded as requirement but i don't want that to be hardcoded.
Also i am using a django forms  to display this.


How can i design this form field as well in models or What should be the type of this field both in models and forms such that weekdays remain dynamic(i can simply generate them from loop) and the user can fill the time  and when he hits submit it will get saved.


Thanks in advance.
