Fixing a NoReverseMatch Error for a Django Project
I am trying to fix a No Reverse Match error for my django project but I am unable to figure out the reason and the sequence of thinking to fix it. My objective is to click on a button and change the status of a boolean from False to True and if the status is False to appear and if it is true disappear. Here is the model: class Workout(models.Model): active = models.BooleanField(default=False) Here is the view: def change_status(request, pk): url = request.META.get('HTTP_REFERER') # get last url startsession = Workout.objects.get(id=pk) startsession.active = True startsession.save() return HttpResponseRedirect(url) Here is the template: {% if startsession.active %} <button disabled="disabled" type="button">Start the workout</button> {% else %} <a href="{% url 'my_gym:bla' startsession.pk %}"> <--------Error here <button type="button">Start the workout</button> </a> {% endif %} here is the url: path('workout/bla/<int:pk>/', change_status, name='bla'), and finally here is the error Traceback: Traceback (most recent call last): File "C:\Users\User\Desktop\Portfolio\venv\lib\site-packages\django\core\handlers\exception.py", line 47, in inner response = get_response(request) File "C:\Users\User\Desktop\Portfolio\venv\lib\site-packages\django\core\handlers\base.py", line 204, in _get_response response = response.render() File "C:\Users\User\Desktop\Portfolio\venv\lib\site-packages\django\template\response.py", line 105, in render self.content = self.rendered_content File "C:\Users\User\Desktop\Portfolio\venv\lib\site-packages\django\template\response.py", line 83, in rendered_content return template.render(context, self._request) File "C:\Users\User\Desktop\Portfolio\venv\lib\site-packages\django\template\backends\django.py", line 61, in render return self.template.render(context) File "C:\Users\User\Desktop\Portfolio\venv\lib\site-packages\django\template\base.py", line 170, in render return self._render(context) File … -

Zero Values Not Shown in Integer Field of Django Form
In a Django project, I have a very simple form with three integer fields: class SpecItemForm(forms.Form): n1 = forms.IntegerField() n2 = forms.IntegerField() n3 = forms.IntegerField() def __init__(self, *args, **kwargs): super(SpecItemForm, self).__init__(*args, **kwargs) I instantiate the form from views.py with code like this: initial_values = {} initial_values['n1'] = 1 initial_values['n2'] = 0 initial_values['n3'] = 3 form = SpecItemForm(initial=initial_values) I expect the form to be rendered with the specified initial values for the three integer fields but this only works for non-zero initial values. For instance, in the example above, I see the initial values for fields n1 and n3 (initial values are, respectively, '1' and '3') but not for n2. Why is an initial value of zero not rendered? -

Django dynamic filter from user input with json date
I need to have a dynamic filter for the user(Admin). There the Admin inputs a date and based on that date Admin sees results to that corresponding date. My problem right now is, I convert it to json bc I dont think that django can do that. the model would be like that class employeemodel(etc): name = etc something = etc from date 1 = date 1 status 1 = status 1 to date 1 = to date 1 from date 2 = date 2 status 2 = status 2 to date 2 = to date 2 I cant lookup every entry in that model, so I have a _set in my tempalte bc the user(admin) searches for entries from user(staff) {% for i in something.employeemoddel_set.all %} {{i.from date 1}} {{i.status 1}} {{i.to date 1}} {{i.from date 2}} {{i.status 2}} {{i.to date 2}} etc Now the admin user sees all entries from one staff user. Admin now needs to have an input field where he can enter a date. Based on that date the entry from staff user in the employeemodel now should show either status 1 or 2 or nothing bc of the date input from Admin. How should … -

How to configure Django Dynamic Menu with the URLs.py
My app is generating a list that would be the side menu, like this: Views.py: def generate_menu(request): array = [] deviceList = [] f1 = open('dictionary.txt', 'r') array = f1.read() array = literal_eval(array) for i in sorted(array): deviceList.append(i) f1.close() context.update({'deviceList': deviceList}) return render(request, "device_list.html", context) Now in my Template, I am doing this to create the menu based on dic file: device_list.html: <nav id="sidebar"> <ul class="list-unstyled components"> <li class="active"> <a href="device_list">Device List</a> </li> {% block devices %} {% for each in deviceList %} <li> <form action="/{{each}}" method="POST"> {% csrf_token %} {{ form.as_p }} <button type="submit" value={{each}} name='DEVICES'>{{each}}</button> </form> </li> {% endfor %} {% endblock %} </ul> </nav> URLs.py: url(r'^$', app.views.index), url(r'^(?P<string>.+)$', app.views.generate_menu, name='DEVICES'), and it doesn't work here. So how can I change the URL in a way to accept all kind of request like http://127.0.0.1/Device* because all device list names, are different and they need their own url. So I need to have a url path that is dynamic. -
