I am creating a quiz app in django. here is the model:
class Quiz(models.Model): title = models.CharField(max_length=200) description = models.TextField() publish = models.BooleanField(default=False) def __unicode__(self): return self.title class Question(models.Model): quiz = models.ForeignKey(Quiz) question = models.TextField() hint = models.TextField() def __unicode__(self): return self.question class Option(models.Model): question = models.ForeignKey(Question) option = models.CharField(max_length=250) correct = models.BooleanField(default=False) def __unicode__(self): return self.title
Each question can only have one answer. This is where the problem comes in. I haven't been able to figure out how to write the admin form for Option model such that for each question, only one of the options can have correct=True.
I can use radio buttons for each question but don't know how to restrict them such that only one can be selected for one foreign key.
I'm not sure how that can be done with reverse look up.
I know this is not exactly what you want, but is quite close. Can you go ahead and try this in the admin.py
admin.site.register(Quiz) #admin.site.register(Option) #Include this if required class OptionInline(admin.TabularInline): model = Option @admin.register(Question) class QuestionAdmin(admin.ModelAdmin): inlines = [ OptionInline, ]
How to make radio buttons in Django admin, Django model with choices will make use of select by default. To use radio buttons, you will have to to use the RadioSelect widget. See django In this article, we show how to create radio buttons in a Django form. Radio buttons are a group on buttons on a form that allows a user to make a choice. Only one radio button can be selected. Unlike check boxes, which can allow for multiple items to be selected, with radio buttons, only one item can be selected.
I understood your question like this: you want to change your code because only one option should be right. Why don't you add this line to Question:
right_answer = models.ForeignKey(Option)
Like this, you needn't the boolean
correct. Your also could add a Manager to this who returns any option which should be chooseable (you override the method
get_queryset(), and this manager should have this line at get_qeryset():
q.option_set.all() where q is there Question. (Without this any option, although its matched with another Question, could be marked.)
I'm not sure whether the secont part would work neither whether its a good way, but the first part is the important one.
