Django how to connect user profile model with comment model for showing data from user profile?

I want to show user profile picture publicly in my blog comment section. I tried to use foreignkey in my comment model for connect user profile model then use this in my html for showing profile picture but didn't work.
<img src="{{blogcomment.userprofile.profile_pic.url}}"> #didn't show any profile picture until I manually go to admin panel and set foreignkey of userprofile in my blogcomment model.
here is my full code:
userprofile model
class UserProfile(models.Model):
user = models.ForeignKey(settings.AUTH_USER_MODEL,on_delete=models.CASCADE,related_name="userprofile")
slug = models.SlugField(max_length=2000,unique=True,blank=True,null=True)
profile_pic = models.ImageField(upload_to='profile/images/',validators=[validate_file_size,FileExtensionValidator( ['png','jpg'] )],blank=True,null=True)
blogcomment model:
class BlogComment(models.Model):
blog = models.ForeignKey(Blog,on_delete=models.CASCADE,null=True, blank=True,related_name="blogcomment_blog")
comment = models.TextField(max_length=50000)
name = models.CharField(max_length=250)
userprofile= models.ForeignKey(UserProfile,on_delete=models.CASCADE,null=True,blank=True)
user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name='user_comment',blank=True,null=True)
views.py:
if comment_form.is_valid():
isinstance = comment_form.save(commit=False)
isinstance.user = request.user
isinstance.blog = blog
isinstance.save()
my html template:
{% for q in queryset %}
{{q.user.first_name}}
{{q.comment}}
<img src="{{q.userprofile.profile_pic.url}}">
{%endfor%}
my froms.py
class CommentFrom(forms.ModelForm):
captcha = CaptchaField()
class Meta:
model = BlogComment
fields = ['name','email','comment','parent','sno','blog','user']
my userprofile forms.py
class ProfileFroms(forms.ModelForm):
class Meta:
model = UserProfile
fields = ["profile_pic","mobile","country","website_link","skype","twitter"]
userprofile views.py
class UserProfileUpdate(UpdateView):
model = UserProfile
form_class = ProfileFroms
template_name = 'members/profileupdate.html'
success_url = reverse_lazy('members:user-profile-private')
html template for saving userprofile forms
<form method="POST" enctype="multipart/form-data" runat="server">
{% csrf_token %}
{{form}}
</form>

Finally I solved my problems. As Willem Van Onsem said I am missing somethings in my froms. I need to be save userprofile forignkey with my comment model when any new comment posted. I am using this queryset UserProfile.objects.filter(user=request.user) for find current id then pass this id in forms.
{%for i in user_profile%}
<input type="hidden" name='userprofile' value="{{i.id}}">
{%endfor%}

How to pass data from Django Template to View

I have a template where customer details are displayed, along with a 'Create Lead' button at the bottom. This should take the user to the Lead creation form page where the customer field should be pre-selected.
I'm new to django. Based on responses of previous similar questions, I came up with the below code. But when I click the 'Create Lead' button, the url changes from "http://127.0.0.1:8000/sales/customer/21" to "http://127.0.0.1:8000/sales/customer/21/?customer_id=21" but nothing happens on the page. I tried with POST method and csrf token also, but it gives HTTP ERROR 405. Could some please help here.
Also, I've separate view for creating a Lead, which is sort of duplication of CreateView for Lead. And I believe that's not how it's supposed to be. What is the way to club them both in single view.
Below are the code snippets.
Models.py
class Customer(models.Model):
name = models.CharField(max_length=256)
email = models.EmailField(unique=True)
phone = models.PositiveIntegerField()
class Lead(models.Model):
customer = models.ForeignKey(Customer,related_name='Leads',on_delete=models.PROTECT)
destinations = models.CharField(max_length=256)
lead_source = models.CharField(max_length=256,choices=lead_source_choices,default='FNF')
lead_source_id = models.CharField(max_length=25,blank=True)
lead_status = models.CharField(max_length=25,choices=lead_status_choices,default='NEW')
remarks = models.TextField(blank=True)
trip_id = models.CharField(max_length=10,editable=False,unique=True,default="IN"+uuid.uuid1().hex[:5].upper())
creation_date = models.DateField(auto_now=True)
Forms.py
class LeadForm(forms.ModelForm):
class Meta:
model = Lead
fields = ('customer','destinations','lead_source','lead_source_id','lead_status','remarks')
class LeadFromCustomerForm(forms.ModelForm):
class Meta:
model = Lead
fields = ('destinations','lead_source','lead_source_id','lead_status','remarks')
Template
<form method="GET">
<input type="hidden" name="customer_id" value="{{customer.id}}">
<a href="{% url 'SalesApp:lead_create_from_customer' %}">
<button class="btn btn-warning btn-lg float-right" type="submit">Create Lead</button></a>
</form>
Urls.py
path('lead/create/',views.LeadCreateView.as_view(),name='lead_create'),
path('lead/create/customer/',views.LeadCreateFromCustomerView.as_view(),name='lead_create_from_customer')
Views.py
class LeadCreateView(LoginRequiredMixin,UserPassesTestMixin,CreateView):
form_class = LeadForm
model = Lead
def test_func(self):
return self.request.user.groups.filter(name='Sales').exists()
class LeadCreateFromCustomerView(LoginRequiredMixin,UserPassesTestMixin,CreateView):
form_class = LeadFromCustomerForm
model = Lead
def test_func(self):
return self.request.user.groups.filter(name='Sales').exists()
def form_valid(self,form):
customer_id = self.request.GET.get("value")
form.instance.customer = Customer.objects.get(id=customer_id)
return super(LeadCreateFromCustomerView,self).form_valid(form)

Django access foreignkey fields in a form

I'm working on a Virtual Library app (using Django v2.1, python v3.5) where anyone should be able to access the book catalog and request a loan by simply leaving some personal info like name, surname, email, etc.
These are some of the models in models.py:
class Profile(models.Model):
name = models.CharField(max_length=50)
# more fields like surname, email, phone...
class TrackBook(models.Model):
# Somefields to keep track of date and status...
borrower = models.ForeignKey(Profile, on_delete=models.SET_NULL, null=True, blank=True)
class Book(TrackBook):
#info about title, author, etc.
What I'm trying to do is to update a Book instance's borrower with a Profile instance that I created in the Form.
1)I've tried directly accessing borrower fields in a BookForm, but it didn't work.
# views.py
class BookRequestView(UpdateView):
template_name = 'core/book_request.html'
model = Book
form_class = BookProfileForm
#forms.py
class BookProfileForm(forms.ModelForm):
class Meta:
model = Book
fields = ['borrower']
# book_request.html
<form class="" action="" method="post">
{% csrf_token %}
<div class="row">
{{ form.borrower.name }}
<! -- and all other fields -->
</div>
{% for field in form.hidden_fields %}
{{ field }}
{% endfor %}
<button type="submit" class="btn btn-block btn-success btn-flat">Save</button>
</form>
2) I've tried creating an inlineformset_factory() of Profile model but it doesn't work since what I want to achieve is create a profile form inside the book form, not viceversa. So the example here is not what I'm looking for.
Maybe I'm going out of my mind for a very simple thing, but I can't seem to find any compatible solution for this problem... Any help/suggestion is welcome. Thanks in advance.

You need a form based on Profile, not Book. Your view then needs to create the profile and then set the book's borrower to that.
class BookProfileForm(forms.ModelForm):
book = forms.ModelChoiceField(queryset=Book.objects.all())
class Meta:
model = Profile
fields = ['name', 'address',...]
class BookRequestView(CreateView):
template_name = 'core/book_request.html'
model = Book
form_class = BookProfileForm
def form_valid(self, form):
borrower = form.save()
book = Book.objects.get(self.kwargs['book_id'] # or whatever is in your URL
book.borrower = borrower
book.save()
return redirect(self.get_success_url())

Error Generic detail view must be called with either an object pk or a slug, even with the pk

I'm trying to update records of a view which has a foreign key field, due to this I'm getting an error, since I tried to update another model without a foreign key field and it worked very well.
There are other quetions like this, but in my case I'm passing the pk.
urls.py
urlpatterns = [
url(r'^info/(?P<studentpk>\d+)/update/$', views.updatestudent.as_view(), name="updatestudent"),
]
views.py
class updatestudent(UpdateView):
model = Student
form_class = forms.studentform
template_name = "temp/updatestudent.html"
def get_success_url(self):
return reverse("courses")
updatestudent.html
<form action="" method="post">{% csrf_token %}
{{ form.as_p }}
<input type="submit" value="Update" />
</form>
models.py
class Student(models.Model):
classfk = models.ForeignKey(Class)
name = models.CharField(max_length=100)
birth_date = models.DateField('Birthdate')
def __str__(self):
return self.name
error
AttributeError: Generic detail view updatestudent must be called with either an object pk or a slug.

Django doesn't expect you to use studentpk in the URL pattern. The easiest fix is to use pk instead.
url(r'^info/(?P<pk>\d+)/update/$', views.updatestudent.as_view(), name="updatestudent"),
If you really want to use studentpk, then set pk_url_kwarg in the view.
class updatestudent(UpdateView):
model = Student
form_class = forms.studentform
template_name = "temp/updatestudent.html"
pk_url_kwarg = 'studentpk'
Note that in Python, the recommended style is to name your class based view UpdateStudent, and your form class StudentForm.

How to make django crispy form to hide a particular field?

I'm trying to make my date_modified field as hidden since I have passed datetime.now parameter on defining date_modified field in model.
model.py
class Guide(models.Model):
name = models.CharField(max_length=50)
sno = models.CharField(max_length=50)
date_created = models.DateTimeField(default=datetime.now, blank=True)
date_modified = models.DateTimeField(default=datetime.now, blank=True)
def __unicode__(self):
return unicode(self.name)
views.py
class GuideFormUpdateView(UpdateView):
model = Guide
fields = ['name', 'sno', 'date_modified']
template_name_suffix = '_update_form'
success_url = reverse_lazy('Guides')
corresponding form forms.py looks like
<form role="form" method="POST" action="{% url 'Guideform-edit' object.pk %}"
class="post-form form-horizontal" enctype="multipart/form-data">{% csrf_token %}
{{ form|crispy }}
<button type="submit" value="Upload" class="save btn btn-default btn-primary center-block">Update</button>
</form>
This form displays date_modified field. But I don't want this field on frontend instead I want the value of this field in model or db_table should get updated. I know how to hide this particular field in jquery but I don't want to touch those js tools. Is there any way to make crispy to exclude that particular field like {{ form|crispy|exclude:date_modified }} ..

Instead of using Generic Form that your UpdateView will use implicitly, create your custom Form. And in your custom Form change the widget of the date_modified field.
In your forms.py
from django.forms import ModelForm, HiddenInput
class GuideForm(ModelForm):
def __init__(self, *args, **kwargs):
super(GuideForm, self).__init__(*args, **kwargs)
self.fields['date_modified'].widget = HiddenInput()
class Meta:
fields = ('name', 'sno', 'date_modified', )
model = models.Guide
In your views.py
class GuideFormUpdateView(UpdateView):
model = Guide
form_class = forms.GuideForm
template_name_suffix = '_update_form'
success_url = reverse_lazy('Guides')
To automatically update date_modified whenever you update the record, you need to use attributes auto_now and auto_now_add instead of default. See Docs. So your model will be
class Guide(models.Model):
name = models.CharField(max_length=50)
sno = models.CharField(max_length=50)
date_created = models.DateTimeField(auto_now_add=True, blank=True)
date_modified = models.DateTimeField(auto_now=True, blank=True)
def __unicode__(self):
return unicode(self.name)

You can hide a field in a form class like so:
Field('field_name', type="hidden")
Where Field is from crispy_forms.layout
Don't forget that if he field cannot be left empty, you'll still need to pass an appropriate value before saving it.
Abstract example:
class GuideFormHiddenField(GuideFormUpdateView):
def __init__(self, *args, *kwargs):
Field('date_modified', type="hidden")
This is the easiest way. You can of course make an entirely new form, or implement your fields individual, and use a condition to determine the visibility of a certain field; which would be something like if User.is_authenticated(): ... .

I think this should work:
from django.forms.models import modelform_factory
class GuideFormUpdateView(UpdateView):
model = Guide
form_class = modelform_factory(Guide, widgets={"date_modified": HiddenInput })
fields = ['name', 'sno', 'date_modified']
template_name_suffix = '_update_form'
success_url = reverse_lazy('Guides')
See here modelform_factory.
