How can I display country, and city of an UserType1 object in template?
class UserType1(models.Model):
user=models.OneToOneField(User,parent_link=True,primary_key=True)
country = models.CharField(max_length=50)
city = models.CharField(max_length=50)
def __str__(self):
return str(self.user)
def get_country(self):
return self.country
def get_city(self):
return self.city
I have the below in views.py
def profile(request,userid):
basic_info = User.objects.get(pk=int(userid))
profile = UserType1.objects.filter(user=int(userid))
template_name = 'users/profile.html'
return render(request, template_name, {'userid':userid,'basic_info':basic_info, 'profile':profile})
and the following in template
{% if profile %}
{{ profile.get_city }}
{{ profile.city }}
{% endif %}
Neither worked. Thanks!
It looks like you are accessing properties on a queryset, rather than a model instance, as you haven't called get on UserType1.
Try:
profile = UserType1.objects.get(user=int(userid))
As an aside though, a small change would simplify your code a little:
user = models.OneToOneField(User, parent_link=True, primary_key=True, related_name='profile')
...
basic_info = User.objects.get(pk=int(userid))
profile = basic_info.profile

When I enter my user profile page, I want it to see the total number of orders until today. i tried aggregate and annonate but it's not work. I hope so i use filter method but i don't know how to do it.
Orders count = adet in model
I added ""if siparis.bayi_id == user.id"" so that the user entering can take action on his orders.
Temp Html
{% for siparis in siparis %}
{% if siparis.bayi_id == user.id %}
<strong>{{ a }}</strong><br><small>Siparişler Toplamı</small>
{% endif %}
{% endfor %}
Model Siparis means order
class Siparis(models.Model):
bayi = models.ForeignKey('auth.User', verbose_name='bayi', on_delete=models.CASCADE, related_name='bayi',limit_choices_to={'groups__name': "BayiGrubu"})
urun = models.ForeignKey(Urun, on_delete=models.CASCADE)
adet = models.IntegerField()
tarih = models.DateTimeField()
status = models.BooleanField()
#property
def miktar(self):
return (self.adet * self.urun.fiyat)
#property
def fiyat(self):
return self.urun.fiyat
class Meta:
verbose_name = 'Bayi Sipariş'
verbose_name_plural = 'Bayi Siparişleri'
views
def bayi_bayidetay(request):
siparis = Siparis.objects.all()
urunler = Urun.objects.all()
bayiler = bayi_bilgi.objects.all()
a = Siparis.objects.aggregate(Sum("adet"))
return render(request,'bayi/bayi_detay.html',{'bayiler':bayiler,'siparis':siparis,'urunler':urunler, 'a': a})
Thank you
You can try add filter after a, like this:
a = Siparis.objects.filter(bayi=request.user).aggregate(Sum("adet"))
I have a following models.py for my Django blog, I made a following views.py to pass the value of the slug for my URL parameter.
However I am struggling to create a model in views to get other data(person & description) from Category class.
I have tried some patterns by myself but can not pass them to HTML. (always Error or not showing)
Can you please give me some idea of how to solve this.
models.py
class Category(models.Model):
person = models.CharField(max_length=20)
description = models.TextField()
slug = models.SlugField()
def __str__(self):
return self.person
views.py
def blog_category(request, category):
posts = Post.objects.filter(categories__slug__contains=category).order_by("-created_on").distinct()
context = {"category": category, "posts": posts}
return render(request, "blog_category.html", context)
HTML(Localhost:8000/slug)
{{ person }}
{{ description }}
this is full code of my models.py
class Category(models.Model):
person = models.CharField(max_length=20)
description = models.TextField()
slug = models.SlugField()
def __str__(self):
return self.person
class Recommender(models.Model):
recommender_name = models.CharField(max_length=20)
slug = models.SlugField()
def __str__(self):
return self.recommender_name
class Post(models.Model):
book_title = models.CharField(max_length=255)
author = models.CharField(max_length=255)
book_link = models.CharField(max_length=255)
recommenders = models.ForeignKey("Recommender", on_delete=models.CASCADE,)
source = models.TextField()
source_link = models.CharField(max_length=255)
created_on = models.DateTimeField(auto_now_add=True)
last_modified = models.DateTimeField(auto_now=True)
categories = models.ManyToManyField("Category", related_name="posts")
slug = models.SlugField()
def __str__(self):
return self.book_title
posts = Post.objects.filter(categories__slug__contains=category).order_by("-created_on").distinct()
Is going to return a queryset. It can have more than one instance of the model class (since you are using filter). In your context you are sending this queryset as posts to your templates.
So in your HTML you can use something like this. You need to use a for loop since there can be more than one item in posts.
{% for post in posts %}
{% for category in post.categories.all %}
{{ category.person }}
{{ category.description }}
{% endfor %}
{% endfor %}
I would look at this example.
Namely, if you render the template like it is shown in the example, you should be able to do
{{ category.person }} {{ category.description }}
I'm new in django.I want to retrieve all the records from related models and display the dynamic data in templates. I tried by using raw sql also but i could not display dynamic data templates.
models.py:
class NewRegistration(models.Model):
houseowner_name_en = models.CharField(max_length=30)
ward_no = models.ForeignKey(system_settings.models.Wardno)
contactno = models.CharField(max_length=30)
construction_type = models.ForeignKey(system_settings.models.ConstructionType)
taxpayer_id = models.CharField(max_length=30, blank=True, null=True)
cen = models.IntegerField()
is_forwarded = models.BooleanField(default=False)
class Application(models.Model):
registration_date = models.CharField(max_length=15)
building_use = models.ForeignKey(to=system_settings.models.BuildingUse)
building_category = models.CharField(max_length=30)
building_structure_category = models.ForeignKey(to=system_settings.models.BuildingStructureCategory)
building_storey = models.IntegerField(blank=True, null=True, default=0)
reg = models.ForeignKey(NewRegistration)
class Landowner(models.Model):
landowner_type = models.CharField(max_length=30)
lo_salutation = models.CharField(max_length=30)
lo_name_np = models.CharField(max_length=30)
lo_citizenship_issue_date = models.CharField(max_length=30)
reg = models.ForeignKey(NewRegistration)
views.py:
def export(request):
all_objects = NewRegistrationModel.objects.all()
# houseowner= all_objects.houseownerinfo_set.all()
app_all=Application.objects.all()
landinfo=Landinfo.objects.all()
return render(request, 'exports.html', {'all_objects': all_objects})
I did it like this.
views.py
def export(request):
all_objects = NewRegistration.objects.all()
return render(request, 'exports.html', {'all_objects': all_objects})
exports.html
# in template when displaying
{% for registration in all_objects %}
{{ registration.fiscalyear }}
{% for owner in registration.landowner_set.all %}
{{owner.landowner_type}}
{{owner.lo_wardno}}
{% endfor %}
{% endfor %}
you can use generic.ListView in your views.py file like that:
class Export(generic.ListView):
model = NewRegistration
template_name = "your_template_name.html"
def get_queryset(self):
return NewRegistration.objects.all()
def get_context_data(self, **kwargs):
context = super(Export, self).get_context_data(**kwargs)
context['app_all'] = Application.objects.all()
context['landinfo'] = Landingo.objects.all()
return context
you can accees the datas in your template like that {{ app_all }} or {{ landinfo }}.
Have a quick question. Trying to use a relational model in one DetailView. However, no matter what I try the data does not display. I've tried a few versions of template tags to no avail.
html
{% for parts in relatedparts %}{{ parts.name }}
</div>{% endfor %}
views.py
class ErrorCodeView(DetailView):
context_object_name = 'error_code_details'
model = models.ErrorCodes
template_name = 'error_code_details.html'
def get_context_data(self, **kwargs):
# xxx will be available in the template as the related objects
context = super(ErrorCodeView, self).get_context_data(**kwargs)
context['relatedparts'] = RelatedParts.objects.filter(name=self.get_object())
return context
models.py
class ErrorCodes(models.Model):
name = models.CharField(max_length=256)
description = models.CharField(max_length=400)
instructions = models.CharField(max_length=256)
PartsNeeded = models.CharField(max_length=120, default='')
usercomments = models.CharField(max_length=400, default='', blank=True)
relpic = models.ImageField(upload_to='media/',blank=True)
relpictwo = models.ImageField(upload_to='media/',blank=True)
def __str__(self):
return self.name
def get_absolute_url(self):
return reverse("errorcodes:errorcodeview",kwargs={'name':self.name})
class RelatedParts(models.Model):
name = models.CharField(max_length=256)
related_error_code = models.ForeignKey(ErrorCodes, on_delete=models.PROTECT)
def __str__(self):
return self.name
You don't need to do this at all. You can follow the relationship in the template.
{% for part in object.relatedparts_set.all %}{{ part.name }}{% endfor %}
You don't need any code in the view to enable this.
could it be that "name=self.get_object()" should be "name=self.get_object().name" ?
You currently have:
context['relatedparts'] = RelatedParts.objects.filter(name=self.get_object())
but that is probably producing an empty queryset.
I am working on a product app on Python 2.7 / Django 1.7.
I have a model for product namely 'product_profile' and I want to allow my customer (end user) to ask any thing regarding specific products using a form.
However I am unable to allow user to automatically select the product (foreign key) and the customer has to select from a drop-down which quite irrational. I have also assigned the foreign key in url-variable.
here is my code:
MODEL.PY
class ProductProfile(models.Model):
category = models.ForeignKey(Category)
brand = models.ForeignKey(Brand)
product_name = models.CharField(max_length=128)
model_name = models.CharField(max_length=128)
generation = models.CharField(max_length=128)
processor = models.CharField(max_length=128)
ram = models.DecimalField(max_digits=2, decimal_places=0)
hdd = models.DecimalField(max_digits=6, decimal_places=2)
optical_drive = models.CharField(max_length=128)
display = models.CharField(max_length=128)
card_reader = models.CharField(max_length=128)
blue_tooth = models.CharField(max_length=128)
web_cam = models.CharField(max_length=128)
warranty = models.CharField(max_length=128)
price = models.DecimalField(max_digits=9, decimal_places=2)
condition = models.TextField()
product_image = models.ImageField(upload_to=update_Product_image_filename)
post_date = models.DateTimeField(db_index=True, auto_now_add=True)
# Override th __unicode__() method to return out something meaningful!
def __unicode__(self):
return self.product_name
class Customer_ps_contact(models.Model):
name = models.CharField(max_length=128)
email = models.EmailField(max_length=75)
subject = models.CharField(max_length=128 )
product = models.ForeignKey(ProductProfile)
message = models.TextField()
phone_regex = RegexValidator(regex=r'^\+?1?\d{9,15}$', message="Phone number must be entered in the format:
'+999999999'. Up to 15 digits allowed.")
phone_number = models.CharField(validators=[phone_regex], blank=True, max_length=15) # validators should be a
list
def __unicode__(self):
return self.name
FORM.PY
class Customer_ps_contactForm(forms.ModelForm):
class Meta:
model = Customer_ps_contact
product = forms.ModelChoiceField(queryset=ProductProfile.objects.all(),
widget=forms.HiddenInput())
fields = ('name','email', 'product','subject','message', 'phone_number')
VIEWS.PY
def product_inquiry(request, product_id):
product = ProductProfile.objects.get(pk=product_id)
if request.method == 'POST':
#form = Customer_ps_contactForm(request.POST, initial = {'product': product})
#form = Customer_ps_contactForm(initial = {'product': product.id})
form = Customer_ps_contactForm(request.POST)
if form.is_valid():
form_data_dict = form.cleaned_data
print form_data_dict['product']
mail_customer_enquriy(form_data_dict) # Function to send email to admin
thank_u_customer(form_data_dict) # Function to send email to customers
form = form.save(commit=False)
form.product = product
form.save()
return home(request)
else:
print ("form is not valid")
print (form.errors)
else:
form = Customer_ps_contactForm()
context_dict = {'form':form, 'product': product}
return render(request, 'product/product_inquiry2.html',context_dict)
URL Patterns
urlpatterns = patterns('',
url(r'^inquiry/(?P<product_id>\d+)/$', views.product_inquiry, name='price'), # Only relevent url given
)
Template : product_inquiry2.html
{% extends 'base.html' %}
{% load crispy_forms_tags %}
{% block body_block %}
{% block title %}Product Inquiry{% endblock %}
<div class="row">
<div class="col-md-10 col-md-offset-1">
<h2 style="font-weight:bold">Enquiry regarding '{{product.product_name}}'</h2>
<hr>
<form id="contact_form" method="post" action=""/>
{% csrf_token %}
{{ form | crispy }}
<input class="btn btn-primary pull-right " type="submit" name="submit" value="Submit the Message" />
</form>
</div>
</div>
{% endblock %}
What should I do?
You know what the product is from the id in the url, so there's no need to include it in your form.
To check that the product exists in the database, you can use the get_object_or_404 shortcut.
def product_inquiry(request, product_id):
product = get_object_or_404(ProductProfile, pk=product_id)
Then leave out 'product' from your list of fields, and remove the ModelChoiceField with hidden input widget.
class Customer_ps_contactForm(forms.ModelForm):
class Meta:
model = Customer_ps_contact
fields = ('name','email','subject','message','phone_number')
You are already setting the product when you save it, but it would be clearer to use the variable name instance to make it clearer what's going on. If you change your mail_customer_enquriy and thank_u_customer methods to use the instance instead of cleaned_data, then you won't have to do anything with form.cleaned_data.
if form.is_valid():
instance = form.save(commit=False)
instance.product = product
instance.save()
mail_customer_enquriy(instance) # Function to send email to admin
thank_u_customer(instance) # Function to send email to customers
return home(request)
