So I am creating auto-generating school schedule app in django.
I try to make a list on a page where user can choose different years of classes (For example if someone want to check groups of 4th year) and now i am facing reverse link problem.
Here is the code:
views.py
#adding students
def addStudent(request):
if request.method == "POST":
year = request.POST["year"]
faculty = request.POST["faculty"]
number = request.POST["group_number"]
f = Students(group_year = year, group_title = faculty, group_number = number)
f.save()
return render(request, "app/AddingForms/addStudents.html")
#viewing
def viewStudents(request, year_id):
arr = Students.objects.filter(group_year = year_id)
context = {"year_id":year_id, 'students':arr}
return render(request, "app/AddingForms/Studentslist.html", context)
models.py
class Students(models.Model):
group_year = models.IntegerField()
group_title = models.CharField(max_length= 10)
group_number = models.IntegerField()
lessons = models.ManyToManyField(Lesson)
def __str__(self):
return self.group_title
urls.py:
#FOR CORE APP
app_name = "scheduleapp"
urlpatterns = [
path("", views.index, name = 'index'),
path("profile/", views.index, name = "profile"),
path("about/", views.about, name = "about"),
path("add/", views.addingMenu, name = "adding"),
path("add-student/", views.addStudent, name = "addStudent"),
path("add-lesson/", views.addLesson, name = "addLesson"),
path("add-teacher/", views.addTeacher, name = "addTeacher"),
path("add-student/<int:year_id>", views.viewStudents, name = "viewStudents")
]
html link
<ul class="list-group">
<li class="list-group-item active" aria-current="true">Currently Active Groups:</li>
<a href = "{% url 'scheduleapp:viewStudents' year_id %}"><li class="list-group-item">1st Year</li></a>
</ul>
What should I do in order to fix this bug?
Here your value of year_id is empty. You need to properly add it to context of the view that is currently visible.
<a href = "{% url 'scheduleapp:viewStudents' year_id %}">
