I'm trying to save a object 'Animal' with the data from my form but im getting a error.
This is my view:
def addAnimal(request):
if request.user.id == None:
return render(request, "deny.html")
else:
if request.method == 'POST':
animal_name = request.POST['animal_name']
animal_type = request.POST['animal_type']
animal_age = request.POST['animal_age']
animal_port = request.POST['animal_port']
animal = Animal(animal_name=animal_name, animal_age=animal_type, animal_type=animal_age, animal_port=animal_port)
animal.save()
return render(request, "home.html", args)
This is the model im trying to save:
class Animal(models.Model):
animal_name = models.CharField(max_length=255)
animal_age = models.ManyToManyField(Age)
animal_type = models.ManyToManyField(Type)
animal_port = models.ManyToManyField(Port)
def __str__(self):
return self.animal_name
And this is my form:
<form method="post" class="form-signin" action="{% url 'addAnimal' %}">
{% csrf_token %}
<img class="mb-4" src="{% static 'images/logo_transparent.png' %}" alt="" width="300" height="300">
<h1 class="h3 mb-3 font-weight-normal text-white">Adicione o seu Animal de Estimação</h1>
<input type="text" id="animal_name" name="animal_name" class="form-control"
placeholder="Nome do Seu Animal de Estimação">
<select class="form-control" id="animal_type" name="ration_type">
<option value="Cão">Cão</option>
<option value="Gato">Gato</option>
</select>
<select class="form-control" id="animal_age" name="animal_age">
<option value="Junior">Junior</option>
<option value="Adulto">Adulto</option>
<option value="Senior">Senior</option>
</select>
<select class="form-control" id="animal_port" name="animal_port">
<option value="Pequeno">Pequeno</option>
<option value="Médio">Médio</option>
<option value="Grande">Grande</option>
</select>
<div>  </div>
<button class="btn btn-lg btn-primary btn-block" type="submit">Adicionar</button>
</form>
And a print if you nedd so:
Update
Im getting a new error:
TypeError at /addAnimal/
Direct assignment to the forward side of a many-to-many set is prohibited. Use animal_age.set() instead.
How can I solve it?
This is because of your POST request.
Try request.POST.get() instead. And/or when you're taking in attributes from POST, try typing for example request.POST['animal name', None] or request.POST.get('animal name', None) Where None can be replaced with any default value. It's a null checking issue I think.

Hey I got this Code to remove my keys:
class AKeysRemove(DeleteView, ProgramContextMixin):
model = AKeys
template_name = 'administration/keys/remove.html'
def dispatch(self, request, *args, **kwargs):
return super(AKeysRemove, self).dispatch(request, *args, **kwargs)
def get_success_url(self):
return reverse('akeys_index', args=[self.get_program_id()])
def delete(self, request, *args, **kwargs):
# Get the query parameters from the request
is_active = request.GET.get('is_active')
category = request.GET.get('category')
# Build a Q object to filter AccessKeys by is_active and category
q_filter = Q()
if is_active is not None:
q_filter &= Q(is_active=is_active)
if category is not None:
q_filter &= Q(category=category)
# Check if there are any filters
has_filters = is_active is not None or category is not None
# Delete the AKeys that match the filter, or just the one AKey
if has_filters:
queryset = self.get_queryset().filter(q_filter)
deleted_count, _ = queryset.delete()
if deleted_count == 1:
messages.success(request, f"One AKey deleted.")
else:
messages.success(request, f"{deleted_count} AKeys deleted.")
else:
obj = self.get_object()
obj.delete()
messages.success(request, f"AKey {obj} deleted.")
return redirect(self.get_success_url())
My url looks like this:
re_path(r'^p/(?P<p_id>[0-9]+)/keys/(?P<pk>[0-9]+)/delete/?$', AKeysRemove.as_view(), name='akeys_delete'),
Deleting one Single Key works fine, but I build myself a filter to delete Keys from a certain category or if they're active or not (is_active)
<div class="row" style="margin-top: 10px">
<div class="col-md-12">
<form method="POST" action="{% url 'akeys_delete' p.id %}" id="delete-akeys-form">
<div class="form-group">
<label for="category-filter">Category:</label>
<select name="category" id="category-filter" class="form-control">
<option value="">All</option>
{% for category in acategories %}
<option value="{{ category.name }}">{{ category.name }}</option>
{% endfor %}
</select>
</div>
<div class="form-group">
<label for="active-filter">Status:</label>
<select name="is_active" id="active-filter" class="form-control">
<option value="">All</option>
<option value="true">Active</option>
<option value="false">Inactive</option>
</select>
</div>
<button type="submit" class="btn btn-default">Delete</button>
</form>
</div>
</div>
The problem now is that when I open my site I get the obvious error:
Reverse for 'akeys_delete' with arguments '(3,)' not found. 1 pattern(s) tried: ['admin/p/(?P<p_id>[0-9]+)/keys/(?P<pk>[0-9]+)/delete/?$']
Which I understand, since its missing the key.pk, I just can't really figure out how I could re-write my code to accept both single objects to delete and multiple?
I'm thankful for any help :)
I assume you want to support multiple functionality with same view. In that case, why not write two urls pointing to the same view, like this:
re_path(r'^p/(?P<p_id>[0-9]+)/keys/(?P<pk>[0-9]+)/delete/?$', AKeysRemove.as_view(), name='akeys_delete'),
re_path(r'^p/(?P<p_id>[0-9]+)/keys/delete/?$', AKeysRemove.as_view(), name='akeys_multi_delete'),
And update the url in template:
<form method="POST" action="{% url 'akeys_multi_delete' p.id %}" id="delete-akeys-form">
This question already has answers here:

You have provided HttpReponse only for POST and valid form. You should give the standard response (with empty form) for fresh entries or posting with errors. Like this:
#login_required
def update_department(request, department_code):
dep_up = Departments.objects.get(department_code=department_code)
if request.method == "POST":
form = DepartmentsForm(request.POST, instance = dep_up)
if form.is_valid():
...
return HttpResponseRedirect('department_list')
form = DepartmentsForm()
return render(request, 'template.html', context={'form': form})
I want to Update/Edit my details on my form. I want to pull the existing details from the database and have them populate on the form, without having the user start from the beginning.

acadYear=self.request.get_all('acadYear') returns a list - apparently in Unicode - which need to become string for putting into data store.
I have tried the following
(1) Use an intermediate variable = does not work.
(2) Encoding to UTF-8 - can't because the list does not have an encode method.
(3) I don't know which element would be chosen [0] or [1]. Hence I can't try
acadYear=self.request.get_all('acadYear')[0].encode('UTF-8').
Such a simple thing - but - why it had to be so complex!
Any help is appreciated. I am losing face before kids.
You have a typo in this line:
<select id="acadYear" name"acadYear">
You need to add an "=" after "name". Because of this typo, your browser is not sending the data for the select field.
