class schedules(models.model): course_name = models.foreignkey(course) location = models.charfield(max_length=128, choices=location_choices, default='south_plainfield') room = models.charfield(max_length=128, choices=room_choices, default='a') start_date = models.datefield(auto_now=false, auto_now_add=false, default=datetime.date.today) start_time = models.charfield(max_length=128, choices=start_time_choices, default='eight-thirty am') end_time = models.charfield(max_length=128, choices=end_time_choices, default='eight-thirty am') instructor = models.foreignkey(instructor) total_hours = models.charfield(max_length=128, choices=total_hours_choices, default='six') # relevant code here frequency = models.charfield(max_length=128) status = models.charfield(max_length=128, choices=status_choices) interval = models.charfield(max_length=128, choices=interval_choices, default='1 day') initiated_by = models.charfield(max_length=128, null=true) schedule_id = models.integerfield(default=0) forms.py
class scheduleform(forms.modelform): course_name = coursechoicefield(queryset=course.objects.filter(status=true), label="course name", widget=forms.select(attrs={'class': 'form-control'})) location = forms.choicefield(choices=location_choices, initial='south_plainfield', label="location", widget=forms.select(attrs={'class': 'form-control'})) room = forms.choicefield(choices=room_choices, initial='a', label="room", widget=forms.select(attrs={'class': 'form-control'})) start_date = forms.datefield(input_formats=['%m/%d/%y'], label="start date", widget=dateinput(format='%m/%d/%y'), help_text="mm/dd/yyyy") start_time = forms.choicefield(choices=start_time_choices, initial='eight-thirty am', label="start time", widget=forms.select(attrs={'class': 'form-control'})) interval = forms.choicefield(choices=interval_choices, initial='1 day', label="interval", widget=forms.select(attrs={'class': 'form-control'})) # hours_per_class = forms.choicefield(choices=hours_per_class_choices, initial='four_and_half', label="hours per class", widget=forms.select(attrs={'class': 'form-control'})) total_hours = forms.choicefield(choices=total_hours_choices, initial='six', label="total hours", widget=forms.select(attrs={'class': 'form-control'})) instructor = instructorchoicefield(queryset=instructor.objects.all(), label="instructor", widget=forms.select(attrs={'class': 'form-control'})) end_time = forms.choicefield(choices=end_time_choices, initial='eight-thirty am', label="end time", widget=forms.select(attrs={'class': 'form-control'})) # relevant code here frequency = forms.multiplechoicefield(widget=forms.checkboxselectmultiple, choices=frequency_choices, label="frequency", help_text="please select @ least one") status = forms.choicefield(widget=forms.radioselect, choices=status_choices, label="status") class meta: model = schedules fields = ('course_name', 'instructor', 'location', 'room', 'start_date', 'start_time', 'end_time', 'interval', 'total_hours', 'frequency', 'status',) views.py
def update_schedule(request, pk): schedule = get_object_or_404(schedules, pk=pk) form = scheduleform(request.post or none, instance=schedule) if form.is_valid(): form.save() return redirect('schedule_list') return render(request, "schedule/update_schedule.html", {'form':form}) update_schedule.html
{% block main_content %} <style> ul { list-style: none; } </style> <h2>update course schedule</h2> <br> <form id="update_schedule_form" method="post" action=""> {% csrf_token %} <div class="row"> {% field in form %} <div class="col-gl-4 col-md-4"> <div class="form-group"> <strong>{{ field.errors }}</strong> {{ field.label_tag }} {{ field.help_text }} <br> {{ field }} <script></script> </div> </div> {% endfor %} </div> <button type="submit" name="submit">update schedule</button> </form> {% endblock %} for reason, choices checked in frequency field not stay checked when go update form instance, though rest of fields do. know is field accepts multiple choices. curiously, table made returns frequency array. know has been asked before, did not answer, i'm hoping can me dilemma. thanks.
