Django get attributes from foreign key's class
django, foreign-keys, model, python
Solution
It is pretty straight forward.
Try this:
def getdegree(self):
return self.course.degree
Documentation here
You can do this safely because `course` is not a nullable field. If it were, you should have checked for existence of object before accessing its attribute.
Problem
I would like to show one attribute from another class. The current class has a foreign key to class where I want to get the attribute. ``` # models.py class Course(models.Model): name = models.CharField(max_length=100) degree = models.CharField(max_length=15) university = models.ForeignKey(University) def __unicode__(self): return self.name class Module(models.Model): code = models.CharField(max_length=10) course = models.ForeignKey(Course) def __unicode__(self): return self.code def getdegree(self): return Course.objects.filter(degree=self) # admin.py. class ModuleAdmin(admin.ModelAdmin): list_display = ('code','course','getdegree') search_fields = ['name','code'] admin.site.register(Module,ModuleAdmin) ``` So what i'm trying to do is to get the "degree" that a module has using the "getdegree". I read several topics here and also tried the django documentation but i'm not an experienced user so even I guess it's something simple, I can't figure it out. Thanks!
