Django filters date range filter is not working

I really don't understand how to connect these two fields or should I just create one. On my front, I have a starting date and end date I can not connect to the backend properly using django-filters Please see the below code
My filters.py
class VideoFolderFilter(FilterSet):
name = CharFilter(field_name='name', lookup_expr='icontains', widget=forms.TextInput(attrs={'class': "form-control"}))
subscription_plan = ModelChoiceFilter( label='subscription_plan', queryset=Plans.objects.all())
start_date_range = DateFromToRangeFilter(field_name='start_date_range', widget=forms.TextInput(attrs={'class': "form-control"}))
end_date_range = DateFromToRangeFilter(field_name='end_date_range', widget=forms.TextInput(attrs={'class': "form-control"}))
def get_date_range(self, start_date_range, end_date_range):
return Sample.objects.filter(sampledate__gte=start_date_range,
sampledate__lte=end_date_range)
class Meta:
model = VideoFolder
fields = '__all__'
widgets = {'start_date_range': DateInput(),}
exclude = [ 'thumbnail_link', 'link', 'name']
My views.py
#login_required
def search_videos(request):
if Subscriber.objects.filter(user=request.user).exists():
subscription = Subscriber.objects.get(user=request.user)
else:
message = "Seams like you don't have subscription with us please select one of the plans"
return redirect(reverse('main'))
video_filter = VideoFolderFilter(request.GET, queryset=VideoFolder.objects.filter(type='video').order_by('-created_date'))
videos = video_filter.qs
return render(request, 'search-videos.html', locals())
Should I change the views.py to query if yes how to date range and other fields will be included
And my search-videos.html
<div class="search-video-form-section mb-3">
<p>Use one or more filters to search below</p>
<form method="GET">
<div class="form-group mb-px-20 filter-form">
<label class="text-base">Name Contains</label>
<!-- <input type="text" class="form-control" placeholder="Keyword" /> -->
{{ video_filter.form.name }}
</div>
<div class="d-flex flex-wrap date-box">
<div class="form-group input-field">
<label class="text-base">Start Date</label>
<div class="input-group input-daterange">
{{ video_filter.form.start_date_range }}
</div>
</div>
<div class="form-group input-field">
<label class="text-base">End Date</label>
<div class="input-group input-daterange">
{{ video_filter.form.end_date_range }}
</div>
</div>
</div>
<div class="form-group filter-form">
<label class="text-base">Subscription</label>
{{ video_filter.form.subscription_plan }}
</div>
<button class="btn text-white bg-info mt-4">Search</button>
</form>
</div>

Django HTML for loop with filter

In my django project, I have an HTML that renders questions header, and inside the question headers I have question items. In my model, Question headers and items are two different entities. I need to show for every header, just the items related to that header. As it shows all items for all questions without any filters. Greatly appreciate any help!
Model:
class Question(models.Model):
question = models.CharField(max_length=240)
mission_section = models.ForeignKey('Mission_Section', on_delete=models.CASCADE)
type_question = models.ForeignKey('Type_Question', on_delete=models.CASCADE)
categories_question = models.ForeignKey('Categories_Question', on_delete=models.CASCADE, default=1)
order = models.IntegerField(default=1)
def __str__(self):
return self.question
class Question_Option(models.Model):
question = models.ForeignKey('Question', on_delete=models.CASCADE,default=1)
option = models.CharField(max_length=240)
correct = models.BooleanField()
order = models.IntegerField(default=1)
View:
class Questions(LoginRequiredMixin, FormView):
template_name = "questions.tmpl"
def get(self, request, pk):
context = {
'pk': pk,
'section': Mission_Section.objects.get(pk = pk ),
'questions_items': Question_Option.objects.filter(question__mission_section__pk=pk).order_by('order','pk'),
'questions': Question.objects.filter(mission_section__pk = pk ),
'question_types' : Type_Question.objects.all(),
'questions_categories': Categories_Question.objects.all()}
return render(self.request, self.template_name, context)
HTML
<input type="hidden" class="form-control" id="section" name="section" value="{{section.id}}" required>
<h1>{{ section.name }}</h1>
<div id="contentDiv">
<ol>
{% for question in questions %}
<div name="question" class="form-group" id="question-{{question.id}}" >
<form class='my-ajax-form' id="form-question-{{question.id}}" method='GET' action='.' data-url='{{ request.build_absolute_uri|safe }}'>
<li><div class="input-group">
{% csrf_token %}
{{ form.as_p }}
<input type="text" value= "{{question.id}}" id="question" name="question-hidden" class="form-control">
<input type="text" value= "{{question.question}}" id="question_name_{{question.id}}" class="form-control" aria-label="Amount" onchange="UpdateQuestion({{question.id}})">
</div>
</form>
<br>
<!-- Options -->
<div id = "question_content_{{question.id}}" name="question-options" class="collapse">
<ol class="example list-group">
{% for qi in questions_items %}
<li class="list-group-item d-flex justify-content-between align-items-center" id={{qi.id}} name="opt-{{question.id}}-{{qi.id}}" onclick="setCorrect({{qi.id}},{{question.id}})" contenteditable="true">{{ qi.option }}
<span class="badge badge-warning badge-pill">-</span>
</li>
{% endfor %} </ol>
<div>
<div class="d-flex justify-content-center">Add Option</div>
<div class="d-flex justify-content-center"> <br><i class="fa fa-plus-circle fa-1x" aria-hidden="true"></i></div>
</div>
</div>
</div></li>
{% endfor %} </ol>

using this answer I figured it out Double loop in Django template
What I need is:
<div id = "question_content_{{question.id}}" name="question-options" class="collapse">
{% csrf_token %}
{{ form.as_p }}
<form class='ajax-form-option' id="form-option-{{question.id}}" method='GET' action='.' data-url='{{ request.build_absolute_uri|safe }}'>
<ol class="example list-group">
{% for qi in question.question_option_set.all %}
<li class="list-group-item d-flex justify-content-between align-items-center" id=option-{{qi.id}} name="opt-{{question.id}}-{{qi.id}}">
<div contenteditable="true">{{ qi.option }}</div>
<div>
<button type="button" name='option-check' class="btn btn-light" value={{qi.id}} id="check-option-{{question.id}}-{{qi.id}}">
<i class="fas fa-check"></i>
</button>
<button type="button" class="btn btn-warning" id="delete-option-{{question.id}}-{{qi.id}}" onclick="deleteOption({{qi.id}})">
<i class="fa fa-trash" aria-hidden="true"></i>
</button>
</div>
</li>
{% endfor %} </ol>
<div onclick="CreateOption({{question.id}})">
<div class="d-flex justify-content-center">Add Option</div>
<div class="d-flex justify-content-center"> <br><i class="fa fa-plus-circle fa-1x" aria-hidden="true"></i></div>
</div>
</form>

Django form doesn't appear on template

I'm currently working on a project that require Django Forms but I ended up with some issues. My form doesn't display at all ... No field appear on my template.
So my code :
models.py
class Place(models.Model):
name = models.CharField(max_length=255)
longitudeMax = models.DecimalField(max_digits=8, decimal_places = 4 ,blank=True)
longitudeMin = models.DecimalField(max_digits=8, decimal_places = 4, blank=True)
latitudeMax = models.DecimalField(max_digits=8, decimal_places = 4, blank=True)
latitudeMin = models.DecimalField(max_digits=8, decimal_places = 4, blank=True)
datasetPath = models.CharField(max_length=255)
isActive = models.BooleanField(default=True)
def __str__(self):
return self.name
def get_place(self, name):
return None
forms.py
class NewPlaceForm(forms.Form):
name = forms.CharField(
widget=forms.TextInput(
attrs={
"placeholder" : "Name",
"class": "form-control"
}
))
longMax = forms.DecimalField(
widget=forms.NumberInput(
attrs={
"placeholder" : "Longitude Max",
"class": "form-control"
}
))
longMin = forms.DecimalField(
widget=forms.NumberInput(
attrs={
"placeholder" : "Longitude Min",
"class": "form-control"
}
))
latMax = forms.DecimalField(
widget=forms.NumberInput(
attrs={
"placeholder" : "Latitude Max",
"class": "form-control"
}
))
latMin = forms.DecimalField(
widget=forms.NumberInput(
attrs={
"placeholder" : "Latitude Min",
"class": "form-control"
}
))
class Meta:
model = Place
fields = ('name', 'longitudeMax', 'longitudeMin', 'latitudeMax', 'latitudeMin')
views.py
def upload(request):
msg = None
if request.method == "POST":
form = NewPlaceForm(request.POST)
if form.is_valid():
form.save()
msg = 'Place created'
else:
msg = 'Form is not valid'
else:
form = NewPlaceForm()
return render(request, "pages/place_upload.html", {"form": form, "msg" : msg})
urls.py
from django.urls import path, re_path

<button class="btn btn-danger">Cancel</button>

I don't see why it doesn't work and it's been several days that I try to make it work ... Did I do something wrong ? Have I forgot something ? Because I don't feel like I did and it's getting on my nerve ahaha

Django handles the form rendering out of the box, to display a basic form, try:
<form method="POST" action="{% url 'namespaced:url' %}">
{ csrf_token %}
{{ form.as_p }}
<input type="submit" value="submit">
</form>
That said, it looks like you're using bootstrap in your template, you might find the package django-bootstrap4 useful (https://github.com/zostera/django-bootstrap4).
Quick example:
pip install django-bootstrap4
and add bootstrap4 to your installed apps.
Then in your template:
{% load bootstrap4 %}
{# Load CSS and JavaScript #}
{% bootstrap_css %}
{% bootstrap_javascript jquery='full' %}
<form action="{% url 'namespaced:url' %}" method="post" class="form">
{% csrf_token %}
{% bootstrap_form form %}
{% buttons %}
<button type="submit" class="btn btn-primary">
Submit
</button>
{% endbuttons %}
</form>
If you want, you can render each field manually using:
{% bootstrap_field field %}, so you can do things like <div class="col-md-6">{% bootstrap_field my_field %}</div>, to manually arrange your form fields on the page.

Keep data in the form after submit

I am implementing search by two fields in form in Django.
I want to keep input data after search.
For example I input "C++" and chose "IT"
then I received Default values
I tried to parse request variable --- e.g. data = request.POST.copy()
but did not achieved result. What is the reason of this problem?
How can I solve this problem?
This is my code:
models.py
class Company(models.Model):
name = models.CharField(max_length=200)
about = models.TextField()
def __str__(self):
return self.name
class Vacancy(models.Model):
company_key = models.ForeignKey(Company, on_delete=models.CASCADE)
title = models.CharField(max_length=200)
salary = models.CharField(max_length=200, default='40.000')
text = models.TextField(default="The text about vacancy")
city = models.CharField(max_length=200, default='Москва')
date_str = models.CharField(max_length=50, default='12 сентября')
created_date = models.DateTimeField(default=timezone.now)
published_date = models.DateTimeField(blank=True, null=True)
CHOICES = [
('ALL', 'ALL'),
('IT', 'IT'),
('FINANCE', 'FINANCE'),
('OTHER', 'OTHER'),
]
department = models.CharField(
max_length=20,
choices=CHOICES,
default='ALL',

self.published_date = timezone.now()
self.save()

In your search results template, you should use {{ query }} and {{ query2 }} and a little bit of logic to populate the text and drop-down boxes.

How to filter foreign key in django filter

I want to get the username using the field user (foreignkey)
I don't know how get the username in the view
model.py
class Publication(models.Model):
user = models.ForeignKey(User, on_delete=models.CASCADE)
filters.py
class PublicationFilter(django_filters.FilterSet):
user = django_filters.CharFilter(lookup_expr='exact')
class Meta:
model = Publication
fields = ['user']
views.py
def publication_list(request):
f = PublicationFilter(request.GET, queryset=Publication.objects.all())
return render(request, 'info/filter.html', {'filter':f})
html
<h2>Lista de sus informes</h2>
<p class="profile-data">
<div class="col-md-4 mt-2 mb-3 ">
<div class="row p-1">
<div class="col-md-12">
<form action="" method="get" >
<b> {{ filter.form.as_p }} </b><br>
<button type="submit">Search</button>
</form>
<ul>
<b>{% for profile in filter.qs %} </b><br>
<b>{{ profile.nombre }} </b><br>
<b>{{ profile.user }} </b><br>
Ver perfil<br>
{% endfor %}

You can use '__' : Publication.objects.filter(user__username="John Doe")
