If you are using Django model form than you have to do something like this first create form class
class Kesif_Form(ModelForm):
class Meta:
model = Iletisim
fields = '__all__'#here you to defined specific you field or all the field
than you have to submit it like this
def kesif_kayit(request):
if request.method=='POST':
form = Kesif_Form(request.POST)
if form.is_valid():
form.save()
return redirect('index')
else:
form = Kesif_Form()
context={'form' : form}
return render(request,'index.html',context)
you don't have save it manually Django Model Form will save it for you.

Django unable to upload image file

I was trying out ImageField in the models, But Image upload do not work when I try to upload from the forms. But it works when I upload it from the admin page.
Any way to debug is also helpful
My model-
class Inventory(models.Model):
"""docstring for Inventory"""
name = models.CharField(max_length=100,default='Something')
image = models.ImageField(null=True, blank=True)
description = models.CharField(max_length=100, default='Describe Something')
price = models.IntegerField( default=0)
My Form-
class InventoryForm(forms.ModelForm):
class Meta:
model = Inventory
fields = ['name','description','price','image']
widgets = {
'name' : forms.TextInput(attrs={"placeholder":"Name", "onfocus":"this.value = '';","onblur":"if (this.value=='') this.value = this.defaultValue","required":""}),
'description' : forms.TextInput(attrs={"placeholder":"Email", "onfocus":"this.value = '';","onblur":"if (this.value=='') this.value = this.defaultValue","required":""}),
'price' : forms.NumberInput(attrs={"placeholder":"Price","onfocus":"this.value = '';","onblur":"if (this.value=='') this.value = this.defaultValue","required":""}),
}
Settings -
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, "media/")
template -
<form action="" method="post" enctype="multipart/form-data"> {% csrf_token %}
{{form}}
<input type="submit" value="Send">
</form>
url -
from django.contrib import admin
from django.urls import path, include, re_path
from django.conf import settings
from django.conf.urls.static import static
urlpatterns = [
path('',include('inventory.urls')),
path('<int:id>',include('inventory.urls')),
path('admin/', admin.site.urls),
]+ static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
My Views-
def index(request):
form = InventoryForm(request.POST or None)
if form.is_valid():
form.save()
form = InventoryForm()
else:
form = InventoryForm()
inventory = Inventory.objects.all()
context = {'form' : form, 'all_inventory' : inventory}
return render(request, 'inventory/index.html',context)
Regards,
Deepak Dash

In your views.py. Change:
form = InventoryForm(request.POST or None)
to
form = InventoryForm(request.POST, request.FILES or None)
Because, Files in django post request are in request.FILES dictionary. You have to send that to forms as well.

How about adding upload_to in models in image field and add default image also this will come in handy later on or not your choice:
models.py
class Inventory(models.Model):
"""docstring for Inventory"""
name = models.CharField(max_length=100,default='Something')
image = models.ImageField(upload_to='/your_file_name/',default='default.png')
description = models.CharField(max_length=100, default='Describe Something')
price = models.IntegerField(default=0)

Search field in Django is not redirecting to detail view

I am adding a search field in my blog so people can put the name of the blog they want to read and a list of items come up and after clicking on any of the list items, it will redirect to the detail view. However, in my case,If I put anything in search, it is not redirecting to a detail view but going to http://127.0.0.1:8000/home/search/2 instead of http://127.0.0.1:8000/home/list/2/.
I have posted my models, views, URLs and template files below.
Is there any reverse method I need to use here to redirect and what changes I need in my template file?
models.py
from django.db import models
class Category(models.Model):
cat_name = models.CharField(max_length = 256, blank = True)
def __str__(self):
return self.cat_name
class Blog(models.Model):
name = models.CharField(max_length = 256, blank = True)
pub_date = models.DateTimeField('date published')
text = models.TextField(blank = True)
category = models.ForeignKey(Category, on_delete=models.CASCADE,
related_name='categories', verbose_name = 'blog_categories')
def __str__(self):
return self.name
views.py
from django.shortcuts import render
from homepage.models import Blog
from django.views.generic import TemplateView, ListView, DetailView
from homepage import models
from django.db.models import Q
class Home(TemplateView):
template_name = 'homepage/index.html'
class BlogListView(ListView):
context_object_name = 'blogs'
model = models.Blog
template_name = 'homepage/blog_list.html'
class BlogDetailView(DetailView):
context_object_name = 'blogs_detail'
model = models.Blog
template_name = 'homepage/blog_detail.html'
def get_queryset(self):
query = self.request.GET.get('q')
return Blog.objects.filter(
Q(name__icontains = query) | Q(name__icontains = query) )
class SearchResultsListView(ListView):
model = Blog
context_object_name = 'blog_list'
template_name = 'homepage/search_result_list.html'
def get_queryset(self):
query = self.request.GET.get('q')
return Blog.objects.filter(
Q(name__icontains = query) | Q(name__icontains = query) )
urls.py
from django.urls import path
from homepage import views
from homepage.views import SearchResultsListView
app_name = 'homepage'
urlpatterns = [
path('', views.Home.as_view(), name = 'index'),
path('list/', views.BlogListView.as_view(), name = 'blog-list'),
path('list/<int:pk>/', views.BlogDetailView.as_view(), name = 'blog-list'),
path('search/', SearchResultsListView.as_view(), name = 'search_result'),
]
index.html
<div class="grid-item-1">
<h1>G</h1>
<input type="button" name="" value="Back to Home" placeholder="">
<form action="{% url 'home:search_result' %}" method = 'get'>
<input type="text" name="q" placeholder="search">
</form>
</div>
search_result_list.html
{% for blog in blog_list %}
<ul>
<li>
{{blog.name}}
{{blog.address}}
here
</li>
</ul>
{% endfor %}
the URL redirects to http://127.0.0.1:8000/home/search/2 and its a 404 page.
how can I redirect it to the detail view page http://127.0.0.1:8000/home/list/1/ and see the detail of the list pulled by search result.

The reason this happens is because {{ blog.id }} just contains a number, for example 2. It will be appended to the URL. You can fix this by prepending the URL with a slash (/) and write list with:
{{blog.name}}
{{blog.address}}
here
But it is likely better to make use of the {% url … %} template tag [Django-doc]:
{{blog.name}}
{{blog.address}}
here
In your BlogDetailView, there is no q parameter, so you can remove the get_queryset:
class BlogDetailView(DetailView):
context_object_name = 'blogs_detail'
model = models.Blog
template_name = 'homepage/blog_detail.html'
# no get_queryset
Furthermore perhaps you should consider renaming the DetailView from blog-list, to blog-detail, or something similar.

Elasticsearch does not return any values. Django

I'm trying to add a search engine for my blog project using ElasticSearch. I think I did everything correctly (using this tutorial), but whatever I write in the search engine, she always returns no results. My database has records and everything looks good. What can happen? Why can not return any results?
Any help will be very appreciated

It's hard to pinpoint exactly where things are breaking without running your application. However, here are some pointers that could help you pinpoint the source of the issue.
Think of your Django application as several layers (following the MVC pattern):
Front-end (view layer): your browser parses and displays the search.html, which has a form on it. The view is what the end user sees and interacts with.
Routing (controller layer): urls.py with map from the URL to the right controller function (in views.py). The controller layer is responsible for getting the right data to return to the user.
Persistence (model layer): models.py and document.py define abstractions and logic to interact (read from and write to) the data stored in your ElasticSearch instance.
Here you're asking "I do an action in the front-end and I don't get the expected result, where is the issue?". The issue could be in any of the above three layers; you should first try to narrow the issue down to one of those layers.
You should try to answer the following questions:
Does your form data make it to the server? (i.e. does the view <> controller interaction work as expected) For this you should use your browser's developer tools to see if you have any error there
Is the controller making the right request to the model? For this you should put print statements or breakpoints (see this question) in the the right function in views.py
Does the model layer query ElasticSearch in the right way? This a harder to debug because Django hides the details of that from you.

Django - Form value ERROR [Simple?]

I will provide all the details necessary to this issue.
Issue description:
I store some input fields with the Django forms (i.e. FormPredmet)
After that I save the form in a model called > Predmet
When pulling the data I have an issue that I didn't have with ModelForm
When printing or displaying (on the page) the Predmet.predavacIme object I get:
<input type="text" name="Ime_Predavaca" value="Elvir" maxlength="50" required id="id_Ime_Predavaca" /> <input type="text" name="Ime_Predavaca" value="Elvir" maxlength="50" required id="id_Ime_Predavaca" /> <input type="text" name="Ime_Predavaca" value="Dzenan" maxlength="50" required id="id_Ime_Predavaca" /> <input type="text" name="Ime_Predavaca" value="Petko" maxlength="50" required id="id_Ime_Predavaca" />
Instead I just wanted a single value of each of these:
Desired output: Elvir,Elvir, Dzenan, Petko
Summary:
I get data using FormPredmet(forms.Form) this is I think the issue
then save the data to the Model Predmet
I try getting any obj for instance: myobj = Predmet.objects.get(pk=1)
after printing one of it's fields print(myobj.imePredavaca())
Instead of a value like "Elvir" I get HTML..input.. (did I store html?)

predavacPrezime=self['Prezime_Predavaca'],
imePredmeta=self['Ime_Predmeta'], razred=razredPredmeta)
myModel.save()

You have to clean form data before you save it into the model. Form returns all data with HTML tags. You can check more in the docs. In your case you need to do something like this:
def save(self, razredID):
razredPredmeta = ModelRazred.objects.get(pk=razredID)
myModel = Predmet(predavacIme=self.cleaned_data['Ime_Predavaca'],
predavacPrezime=self.cleaned_data['Prezime_Predavaca'],
imePredmeta=self.cleaned_data['Ime_Predmeta'], razred=razredPredmeta)
myModel.save()
Also I would recommend to move a save() method from your Form to your View - it is more readable to save models there, forms only process form data.
