Why can't I filter the data by one known in django&

I have a painted filter in view.py which works wonderfully. When I use a common abbreviation in html code, like {{form.as_p}} or {{form|crispy}}, then I can find the data I need, according to one known one. In my case, this is by course, by semester, by type of subject, by institute, and so on, and when I start writing my html code, in order for the search to give the correct answer, all fields must be filled in, although in forms and models I determined that all fields are not required, it turns out that an error in the html code, but I do not know where(
veiws.py:
def buy_files(request):
bdfiles = FeedFile.objects.all()
# bdfiles = UploadFile.objects.all()
form = FileFilterForm(request.GET)
if form.is_valid():
if form.cleaned_data["number_course"]:
bdfiles = bdfiles.filter(feed__number_course = form.cleaned_data["number_course"])
if form.cleaned_data["number_semestr"]:
bdfiles = bdfiles.filter(feed__number_semestr = form.cleaned_data["number_semestr"])
if form.cleaned_data["subjectt"]:
bdfiles = bdfiles.filter(feed__subjectt = form.cleaned_data["subjectt"])
if form.cleaned_data["type_materials"]:
bdfiles = bdfiles.filter(feed__type_materials = form.cleaned_data["type_materials"])
if form.cleaned_data["institute"]:
bdfiles = bdfiles.filter(feed__institute = form.cleaned_data["institute"])
return render(request, 'chat/files/buyfile.html', {'bdfiles': bdfiles, 'form':form})

forms.py
class FileFilterForm(forms.Form):
number_course = forms.IntegerField(label='Курс',required=False, widget=forms.NumberInput(attrs={'class': 'form-control'}))
number_semestr = forms.IntegerField(label='Семестр',required=False, widget=forms.NumberInput(attrs={'class': 'form-control'}))
subjectt = forms.CharField(label='Дисциплина',required=False,widget=forms.TextInput(attrs={'class': 'form-control'}))
type_materials = forms.CharField(label='Тип материала',required=False,widget=forms.TextInput(attrs={'class': 'form-control'}))
institute = forms.CharField(label='Институт',required=False,widget=forms.TextInput(attrs={'class': 'form-control'}))

When you generate a form by something like {{form.as_p}}, all the fields are generated and submitted, even if some of the values associated with them are empty because no choice is made by the user.
When you write out only a few fields, the missing fields aren't submitted at all.
That means, in your views.py, when you refer to them by
form.cleaned_data["number_course"]
you might get an invalid key error, as no data by that name was submitted.
To fix, you can use
form.cleaned_data.get('number_course')
...which should return None if there is no such key, rather than erroring out

Not getting your quetion perfectly But you will get Idea By below code:
<select id="" class="" name="">
{% for i in Product %}
<option value="{{ i.name }}">
{{i.name }}
</option>
{% endfor %}
</select>
Basically you need to use jinja html and loop with the data/model(here Product) which is given from view.py(function) and then you can access each column of model(here name).

To do this you should create a serialiser and pass that as part of the context to the frontend and loop through that.
visit this link to see how t make a serializer docs
After you have created your serializer and lets say you named it ProductSerializer, you then add the below line to the place that passes data to that order page screen in the frontend. The below line serializes your raw queryset and passes it to your frontend to be consumable.
products = Product.objects.all()
products = ProductSerializer(cart, many=True)
context = {"products": products}
Then in your frontend you can access this and loop through like so:
<select id="" class="" name="">
{% for product in products %}
<option value="{{ product.name }}">
{{product.name }}
</option>
{% endfor %}
</select>

How to use 3 seperate filters on 1 page?

I have a page on which are 3 separate forms.
With form 1 I can filter on name (typed in by user) with form method Post
With form 2 I can filter on level (from list) with form method Get
With form 3 I want to filter on school (from list) also with form method Get

<!-- ### END Filters ### -->
Currently form 1 and 2 work, giving a filtered list a little lower on the same page.
form 3 is working too (the right choice is visible behind the URL) but the filtered list stays empty.
part of views.py:
def spells(request):
if request.method == "POST":
spellz = request.POST.get('filter-search-name')
spells = Underdark_Spells.objects.filter(Q(spell_name__icontains=spellz)).order_by('spell_name')
return render(request, 'spells.html', {'spells': spells})
elif request.method == "GET":
level = request.GET.get('filter-search-level')
spells = Underdark_Spells.objects.filter(Q(spell_level=level)).order_by('spell_name')
return render(request, 'spells.html', {'spells': spells})
elif request.method == "GET":
school = request.GET.get('filter-search-school')
spells = Underdark_Spells.objects.filter(Q(spell_school=school)).order_by('spell_name')
return render(request, 'spells.html', {'spells': spells})
else:
spells = Underdark_Spells.objects.all().order_by('spell_name')
return render(request, 'spells.html', {'spells': spells})
def __str__(self):
return self.name
I think the problem is with the way I set it up with if and elif
It looks like this way I can not use request method twice in the same if statement.
If I comment out form 2 code in views.py then form 3 works like a charm.
Is there a way to make it work like this or do i have to create a seperate def for each GET?

You can not have identical conditions in two different if/elif blocks.
Instead you can do this as below:
...
elif request.method == "GET":
if request.GET.get('filter-search-level'):
level = request.GET.get('filter-search-level')
spells = Underdark_Spells.objects.filter(Q(spell_level=level)).order_by('spell_name')
elif request.GET.get('filter-search-school'):
school = request.GET.get('filter-search-school')
spells = Underdark_Spells.objects.filter(Q(spell_school=school)).order_by('spell_name')
return render(request, 'spells.html', {'spells': spells})

You should add a check to see if the item is in the querystring, so:
def spells(request):
if request.method == 'POST' and 'filter-search-name' in request.POST:
spellz = request.POST.get('filter-search-name')
spells = Underdark_Spells.objects.filter(Q(spell_name__icontains=spellz))
elif request.method == 'GET' and 'filter-search-level' in request.POST:
level = request.GET.get('filter-search-level')
spells = Underdark_Spells.objects.filter(Q(spell_level=level))
elif request.method == 'GET' and 'filter-search-school' in request.POST:
school = request.GET.get('filter-search-school')
spells = Underdark_Spells.objects.filter(Q(spell_school=school))
else:
spells = Underdark_Spells.objects.all()
spells = spells.order_by('spell_name')
return render(request, 'spells.html', {'spells': spells})
That being said, the code looks quite "ugly" with a lot of duplicated code. It is also strange to make use of a GET or POST request to search for data. Typically a GET request is used to filter data, a POST request is used to update entities. By using three different forms, you also make it impossible to simply select a level and a school for example to apply two filters.
I would advise to make use of one form where you have multiple items, and make use of django-filter [GitHub] or at least of Django forms [Django-doc] to remove boilerplate code.

Django Forms posting not working - Django simply renders the page again

Basically I have set up a form to create organizations. When I hit the Save button, it simply renders the page again - the POST is not working.
See my code below:

Any help would be greatly appreciated. If you need any additional info, let me know and I will edit the post.

I did not find any code to show the errors in html.
According to the function in views, if the form is not valid, then it renders the page with the form.
Try to add {{form.errors}} to you the html file to see if it has errors?

I managed to solve it.
views.py
#login_required
def organization_add(request):
if request.method == 'POST':
form = OrganizationAddForm(request.POST)
if form.is_valid():
form.organization_code = form.cleaned_data['organization_code']
form.company_name = form.cleaned_data['company_name']
form.legal_name = form.cleaned_data['legal_name']
form.business_registration_no = form.cleaned_data['business_registration_no']
form.vat_registration_no = form.cleaned_data['vat_registration_no']
form.industry_distribution = form.cleaned_data['industry_distribution']
form.industry_education = form.cleaned_data['industry_education']
form.industry_healthcare = form.cleaned_data['industry_healthcare']
form.industry_manufacturing = form.cleaned_data['industry_manufacturing']
form.industry_retail = form.cleaned_data['industry_retail']
form.industry_services = form.cleaned_data['industry_services']
form.effective_start_date = form.cleaned_data['effective_start_date']
form.effective_end_date = form.cleaned_data['effective_end_date']
org = form.save(commit=False)
org.created_by = request.user
org.last_updated_by = request.user
org.save()
return redirect('organizations_settings')
else:
form = OrganizationAddForm()
return render(request, 'settings/add_organization.html', {'form': form})
The issue was that it was not able to capture the user email for the Created By and Last Updated By fields.
This is resolved by using:
org = form.save(commit=False)
org.created_by = request.user
org.last_updated_by = request.user
Note that the following two posts helped me:

MultiSelect field in Django 2 is not working

I'm working on a project using Python(3.7) and Django(2) in which I need to create a multi-select field inside one of my form.
Here's what I have tried:
from models.py:
class ExperimentModel(models.Model):
user = models.ForeignKey(User, related_name='experiments',
on_delete=models.CASCADE)
name = models.CharField(max_length=255)
start_date = models.DateField()
change_date = models.DateField()
end_date = models.DateField()
assets = models.CharField(max_length=450, choices=choices)
goals = models.CharField(max_length=255, blank=True)
comments = models.TextField(max_length=1000)
created_at = models.DateTimeField(auto_now=True)
From forms.py:
class ExperimentForm(forms.ModelForm):
choices = (

assets = forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple,
choices=choices)
class Meta:
model = ExperimentModel
fields = ('user', 'name', 'start_date', 'change_date', 'end_date', 'assets',
'goals', 'comments')
From template.html:
<form method="POST" action="{% url 'new-experiment' %}">
{% if form.errors %}
{% for field in form %}
{% for error in field.errors %}
<div class="alert alert-danger">
<strong>{{ error|escape }}</strong>
</div>
{% endfor %}
{% endfor %}
{% for error in form.non_field_errors %}
<div class="alert alert-danger">

{% endif %}

form = ExperimentForm(post_data)

if form.is_valid():
print('form valid')
form.save(commit=False)
form.user = request.user
form.save()
return HttpResponseRedirect(reverse_lazy('all-experiments'))
else:
return HttpResponseRedirect(reverse_lazy('new-experiment'))
When I select the only one option from multiple assets, the experiment has been created but when select multiple options the request failed, what's can wrong here?
How can I achieve the multi-select functionality for assets for experiment Model?
Also, no error is displaying in the template, even though I have printed the errors in the template, but doesn't any error is displaying on the template.
Thanks in advance!
