python - Returning multiple values independently from __str__ for ModelChoiceField -

i have models.py as:

class foodcategory(models.model):     category = models.charfield(max_length = 50)     content = models.charfield(max_length= 50, null = true,blank=true)     preparation = models.charfield(max_length= 50, null=true, blank=true)     time = models.charfield(max_length=50,null=true, blank=true)     def __str__(self):         return '%s %s %s %s' % (self.category, self.content, self.preparation, self.time) 

now have filled values foodcategory django admin site.and need display these values drop down fields ie dropdown field category, drop down field content , similiarly preparation , time.

forms.py follows:

class foodform(forms.modelform):     category = forms.modelchoicefield(queryset=category.objects.all())     time = forms.modelchoicefield(queryset=category.objects.all())     preparation = forms.modelchoicefield(queryset=category.objects.all())     content = forms.modelchoicefield(queryset=category.objects.all())     class meta:         model = fooditems         fields = ('name','time', 'category', 'content', 'preparation', 'comment',) 

but dropdown fields displaying as:

need seperate starter-soup, veg, american, breakfast category,content, preparation, time respectively

think problem return value of __str__. how can return them individually?

you can achive creating custom modelchoice fields:

class categorymodelchoicefield(modelchoicefield):     def label_from_instance(self, obj):         return obj.category  class timemodelchoicefield(modelchoicefield):     def label_from_instance(self, obj):         return obj.time  class preparationmodelchoicefield(modelchoicefield):     def label_from_instance(self, obj):         return obj.preparation  class contentmodelchoicefield(modelchoicefield):     def label_from_instance(self, obj):         return obj.content 

forms.py :

class foodform(forms.modelform):     category = categorymodelchoicefield(queryset=category.objects.all())     time = timemodelchoicefield(queryset=category.objects.all())     preparation = preparationmodelchoicefield(queryset=category.objects.all())     content = contentmodelchoicefield(queryset=category.objects.all())     class meta:         model = fooditems         fields = ('name','time', 'category', 'content', 'preparation', 'comment',)
