I'm having an issue, what I need is to save a part number into a database table. So everytime a user enters the SOSS it should be save in my table. This is my code but is not saving anything, not sure what I'm doing wrong.
manifiestos.html
<form action="{% url 'manifiestos' %}" method="post"> {% csrf_token %}
<p><label for="date"> Date:</label> <input type="text" name="date" value={% now "Y-m-d" %} /> </p>
<p><label for="soss"> SOSS:</label> <input type="text" name="soss" id="soss" /> </p>
<input type="submit" value="Submit" />
</form>
models.py
class manifiestos_bts(models.Model):
soss = models.CharField(max_length=50)
date = models.DateTimeField(null=True, blank=True)
user = models.CharField(max_length=50)
forms.py
class ManifiestosForm(forms.Form):
soss = forms.CharField()
date = forms.DateTimeField()
user = forms.CharField()
html_views
#login_required(login_url='/msr/login')
def manifiestos(request):
if request.method == 'POST':
form = ManifiestosForm(request.POST)
if form.is_valid():
soss = request.POST.get('soss', '')
date = request.POST.get('date', '')
manifiestos_obj = manifiestos_bts(soss= soss, date= date)
manifiestos_obj.save()
return HttpResponseRedirect(reverse('manifiestos'))
else:
form = ManifiestosForm()
return render(request, 'manifiestos.html', {'form': form})
urls.py
url(r'^manifiestos$', html_views.manifiestos, name='manifiestos'),
Thanks for your time :)
If you need more details just let me know.
Your form.is_valid() will fail because you are not passing user from your template. Either remove it from ManifiestosForm or pass it from manifiestos.html

How to fetch the current object from the deatailed view page in the review function?
I have added the code here. In Product detailed view page it is rendering the page through which I want to take rating and comment for the product . Is there any other way through which I can get the product, user , star, and rating field value and store it in the data base?
I can point out some ways to retrieve the product_id in your review function.
First approach:
You can pass the product_id as a URL parameter. In this case, I hope the review view is called from the product detail page.
So, your url should be something like:
path('review/<int:product_id>', views.review, name="review),
Your view:
def review(request, *args, **kwargs):
star=request.POST.get('rating')
comment=request.POST.get('comment')
user = request.user
productId = kwargs.get('product_id') # change is here
product = Products.objects.get(id=productId)
review = Rating(product=product,user=user,stars=star,comment=comment)
review.save()
return redirect('/')
Your template:
<form method="POST" action="{% url 'review' object.pk %}">
{% csrf_token %}
<input type="hidden" id="rating-value" name="rating">
<textarea style="margin-top:5px;" class="form-control" rows="3" id="comment" placeholder="Enter your review" name="comment"></textarea>
<button type="submit" style="margin-top:10px;margin-left:5px;" class="btn btn-lg btn-success">Submit</button>
</form>
In the template, the object is the object_name you have given to the product object. You can change the object name by adding:
context_object_name = product
in your ProductDetailView.
Second approach:
Pass the product_id as a form data. You can create a hidden input in your template that will contain the product_id as value. For example:
In your template:
<form method="POST" action="review">
{% csrf_token %}
<input type="hidden" id="rating-value" name="rating">
<input type="hidden" name="product_id" value="{{ object.pk }}"> # add a hidden input field
<textarea style="margin-top:5px;" class="form-control" rows="3" id="comment" placeholder="Enter your review" name="comment"></textarea>
<button type="submit" style="margin-top:10px;margin-left:5px;" class="btn btn-lg btn-success">Submit</button>
</form>
Where object is what I mentioned previously.
Then you can retrieve the product_id in view as:
def review(request,slug):
star=request.POST.get('rating')
comment=request.POST.get('comment')
user = request.user
productId = int(request.POST.get('product_id')) # here
product = Products.objects.get(id=productId)
review = Rating(product=product,user=user,stars=star,comment=comment)
review.save()
return redirect('/')
Currently i am working a project for making a student management system for my college.
I have a User model and a profile model. I also added an attendance model with User as the foreign key. I was stuck in while i started writing the form for entering the attendance.
class Attendance(models.Model):
Student = models.ForeignKey(User, on_delete=models.CASCADE)
Hour = models.CharField(max_length=1, blank=False)
Subject = models.CharField(max_length=8, blank=False)
Date = models.DateTimeField(default=timezone.now)
Presence = models.BooleanField(default=False, blank=False)
def __str__(self):
return f'{self.Student}'
This is my template where query set is names of Users that should be the default value. The number of Users, the number of forms should come. With this template i can create only one object, with the values of the last form iterated. When the <form> is inside forloop i get multiple objects with the same values of lastly iterated form.
<form method="POST" action="{% url 'academics' %}" style=" padding: 5%">
{% csrf_token %}
{% for query in queryset %}
<input type="text" name="Student" class="form-control" required id="id_Student" value="{{query}}">
<input type="text" name="Hour" class="form-control" required id="id_Hour">
<input type="text" name="Subject" class="form-control" required id="id_Subject">
<input type="checkbox" name="Presence" required id="id_Presence">
{% endfor %}
<button type="Submit">Submit</button>
</form>
I came to know about formsets, but i don't know how to implement for a complex thing like this. This is my views.py:
def academics(request):
if request.user.is_staff:
form = forms.AttendanceForm()
context = {
'form': form,
'queryset': User.objects.filter(profile__Year='SY',profile__Department='CSE')
}
if request.method == "POST" :
form = forms.AttendanceForm(request.POST)
if form.is_valid():
student = request.POST.get('Student')
hour = request.POST.get('Hour')
subject = request.POST.get('Subject')
boolean = request.POST.get('Presence')
def bool(boolean):
if boolean == 'on':
return 'True'
else:
return 'False'
form = Attendance(Student=student,Hour=hour,Subject=subject,Presence=bool(boolean))
form.save()
return render(request, 'console/academics.html',context)
else:
context = {
'attends': Attendance.objects.all().exclude(Date=timezone.now()),
'todays': Attendance.objects.filter(Date=timezone.now())[:8]
}
return render(request, 'student/academics.html',context)
Can anyone alter the code on how to use formset here. I know am asking an open help instead of asking doubts. Atleast give me hints or correct video tutorial links please!
This is my first project in Django. I am trying to save rating in Django database but when I click on radio buttons the value doesn't store in database. I have tried solutions of Stack Overflow previously uploaded but none helped me in resolving my issue. I was firstly using RadioSelect in forms.py but still having the same problem.
Here is the code:
Model.py
class Product(models.Model):
title = models.CharField(max_length=120)
brand = models.CharField(max_length=120,default="None")
model = models.CharField(max_length=120,default="None")
slug = models.SlugField(blank=True, unique=True)
category = models.CharField(max_length=120 , default="Phone")
price = models.DecimalField(decimal_places=2, max_digits=20, default=39.99)
class Rating(models.Model):
product=models.ForeignKey(Product,default=None, on_delete=models.PROTECT)
user=models.ForeignKey(User,default=None, on_delete=models.PROTECT)
rating = models.CharField(max_length=120)
Views.py
def add_rating(request,id):
product = get_object_or_404(Product, pk=id)
pro = Product.objects.get(id=id)
if request.method == "POST":
form = RatingForm(request.POST)
if form.is_valid():
product = form.cleaned_data['product']
user = form.cleaned_data['user']
rating = form.cleaned_data['rating']
product = request.POST.get('product', ''),
user = request.POST.get('user', ''),
rating = request.POST.get('rating', ''),
obj = Rating(product=product, user=user, rating=rating)
obj.save()
context = {'obj': obj}
return render(request, 'product/detail.html',context)
else:
form=RatingForm()
return HttpResponse('Please rate the product')
Forms.py
from django import forms
from .models import Rating
class RatingForm(forms.ModelForm):
class Meta:
model = Rating
fields = ('product', 'user','rating')
template.py
<form method="POST" action="{% url 'add_rating' product.id %}">{% csrf_token %}
<ul class="rate-area" style="display:inline;position:absolute">
<input type="radio" id="5-star" name="rating" value="5" /><label for="5- star" title="Amazing">5 stars</label>
<input type="radio" id="4-star" name="rating" value="4" /><label for="4-star" title="Good">4 stars</label>
<input type="radio" id="3-star" name="rating" value="3" /><label for="3-star" title="Average">3 stars</label>
<input type="radio" id="2-star" name="rating" value="2" /><label for="2-star" title="Not Good">2 stars</label>
<input type="radio" id="1-star" name="rating" value="1" /><label for="1-star" title="Bad">1 star</label>
<button type="submit" value="Rate">Rate</button>
</ul>
</form>
You're using a "CharField" on your model while you should be using a "ChoiceField", a ChoiceField would then become a dropdown select.
It would also be easier to use generic editing views; https://docs.djangoproject.com/en/2.2/ref/class-based-views/generic-editing/
I have another model which is like below
class Status(models.Model):
name = models.ForeignKey(User, on_delete=models.CASCADE)
status = models.BooleanField(default=False)
I just want to create a form which will render all users from django User model with upper model connected. When click single Status button it will just save that field. I'm using CreateView. How to do that?
<form method="post" action="">
User1 <input type="checkbox" name="status" />
<input type="submit" name="submit" value="Status"/>
</form>
<form method="post" action="">
User2 <input type="checkbox" name="status" />
<input type="submit" name="submit" value="Status"/>
</form>
<form method="post" action="">
User3 <input type="checkbox" name="status" />
<input type="submit" name="submit" value="Status"/>
</form>
You could use Formsets from Django. Through this way, you can set 2 forms in one, get fields from both forms and save them with a single button.
For example, you have two models bounded by a ForeignKey in your models.py file :
class MyModelA(models.Model):
field1 = ...
field2 = ...
class MyModelB(models.Model):
field1 = ...
field2 = models.ForeignKey(MyModelA, ...)
Then, in your forms.py file, you have to bound these both forms thanks to formsets :
from django.forms.models import inlineformset_factory
from .models import MyModelA, MyModelB
MyFormSet = inlineformset_factory(MyModelA, MyModelB, form=MyModelBForm, extra=1, max_num=1)
With this line, your models will be set into the same django form in your template.
Now, in your views.py file, you have to call your formset :
class MyClassCreateView(CreateView):
model = MyModelA
template_name = 'path/to/your/template'
def get_context_data(self, **kwargs):
context = super(MyClassCreateView, self).get_context_data(**kwargs)
context['my_form'] = MyFormSet(self.request.POST or None)
return context
def form_valid(self, form):
context = self.get_context_data()
document = context['my_form']
if document.is_valid():
self.object = form.save()
document.instance = self.object
document.save()
return super(MyClassCreateView, self).form_valid(form)
And finally, in your template.html file, you can call your formset :
<form method="post" action="" novalidate>
{% csrf_token %}
{{ form }}
{{ my_form }}
<input type="submit" class="btn btn-default" value="{% trans 'Save' %}" />
</form>
Hopfully it could help you to set your Django formsets
I have a model:
class Tour(models.Model):
owner_id = models.ForeignKey(User)
name = models.CharField(max_length=50)
location = models.ManyToManyField(Location)
subscribers = models.ManyToManyField(User, related_name="sub")
tour_date = models.DateField(null=True)
description = models.CharField(max_length=300, null=True)
And a template that includes this form:
<form method="post" action="/mytours/">
{% csrf_token %}
<input name="name" value="{{ name }}" class="pull-left" type="text" placeholder="Type the tour name... "></br>
<input name="tour_date" value="{{ tour_date }}" type="text" id="datepicker" placeholder="Pick a tour date..."/>
<button class="btn" data-dismiss="modal" aria-hidden="true">Cancel</button>
<button type="submit" class="btn btn-primary">Save</button>
</form>
And in my views I am trying to add to my database what is filled in the form:
if request.method == 'POST':
location = Location.objects.get(id=1)
name = request.POST.get('name', '')
tour_date = request.POST.get('tour_date', '')
tour = Tour()
tour.owner_id = user.pk
tour.name = name
tour.tour_date = tour_date
tour.location = location
tour.save()
c = {'name':name, 'tour_date':tour_date, 'tour':tour}
c.update(csrf(request))
return render_to_response("myTours.html", c)
I am new in django and I don't know where is the problem.
You're misunderstanding what to do with the CSRF token. You're creating it on POST, but the point is to create it for the original display of the form on the GET request. It is checked by the middleware on POST, so you don't need to add it there.
You should use the render call as recommended by surfeurX, but on the call that displays the form in the first place.
What I do when I implement forms in django is writing a form class and creating an instance of it in the view. Then pass the instance to the template.
# form class eg. in models.py
from django import forms
class TourForm(forms.Form):
name = forms.CharField(max_length=50)
# in the view
if request.method == 'POST':
form = TourForm(request.POST)
if form.is_valid():
# do your stuff here with form data
else:
form = TourForm() # An unbound form
return render(request, 'myTours.html', {
'form': form,
})
in your template you can display the generated form like this:
<form action="/mytours/" method="post">{% csrf_token %}
{{ form.as_p }}
<input type="submit" value="Save" class="btn btn-primary" />
</form>
for further information just look inside the official django forms documentation
You probably need to add django.middleware.csrf.CsrfViewMiddleware to MIDDLEWARE_CLASSES and add a RequestContext to your response:
return render_to_response("myTours.html", c, context_instance=RequestContext(request))
https://docs.djangoproject.com/en/1.3/ref/contrib/csrf/
How do you render your template ??? I think your csrf_token doesn't print any hidden input, add "request" in your template context like:
return render(request, "template.html", {"var": var})
