Thanks for any help
Your post_detail.html extends base.html, hence any content you wish to render must be inside some block and this block also must be present in the parent template (base.html here). You currently have some content outside any block and hence they aren't rendered. Put the HTML inside the block and it will show up:
{% extends 'base.html' %}
{% block content %}
<div class="post-entry">
<h2>{{ post.title }}</h2>
<p>{{ post.body }}</p>
</div>
<p>+ Edit Blog Post</p>
<p>+ Delete Blog Post</p>
<img src="{{ post.header_image.url|default_if_none:'fox.jpeg' }}">
{{ post.body|urlize }}

Pagination with ListView django

I want to create app with search and pagination. Pagination didn't work with ListView.
When I click on the link "next" I am moving from start page http://127.0.0.1:8001/ ---> to the http://127.0.0.1:8001/?city=2 but elements of the list did not change.
And next click to the "next" link did not changes the url ( http://127.0.0.1:8001/?city=2 --> http://127.0.0.1:8001/?city=2).
Could you help me to find error?
I think that error in *.html file, but can't find it
My code:
models.py
from django.db import models
class City(models.Model):
name = models.CharField(max_length=255)
state = models.CharField(max_length=255)
class Meta:
verbose_name_plural = "cities"
def __str__(self):
return self.name
urls.py
# cities/urls.py
from django.urls import path
from . import views
from .views import HomePageView, SearchResultsView
urlpatterns = [
path('search/', SearchResultsView.as_view(), name='search_results'),
path('', HomePageView.as_view(), name='home'),
path('city/<int:pk>/', views.city_detail, name='city_detail'),
]
views.py
from django.shortcuts import render
from django.views.generic import TemplateView, ListView
from .models import City
from django.db.models import Q
from django.shortcuts import render, get_object_or_404
class HomePageView(ListView):
model = City
template_name = 'cities/home.html'
paginate_by = 3
def city_detail(request, pk):
city = get_object_or_404(City, pk=pk)
return render(request, 'cities/city_detail.html', {'city': city})
class SearchResultsView(ListView):
model = City
template_name = 'cities/search_results.html'
def get_queryset(self): # new
query = self.request.GET.get('q')
object_list = City.objects.filter(
Q(name__icontains=query) | Q(state__icontains=query)
)
return object_list
home.html
<!-- templates/home.html -->
<h1>HomePage</h1>
<form action="{% url 'search_results' %}" method="get">
<input name="q" type="text" placeholder="Search...">
</form>
<ul>
{% for city in object_list %}
<li>
<h1>{{ city.name }}</h1>
</li>
{% endfor %}
</ul>
{{page_obj}}
<div class="pagination">
<span class="page-links">
{% if page_obj.has_previous %}
previous
{% endif %}
<span class="page-current">
Page {{ page_obj.number }} of {{ page_obj.paginator.num_pages }}.
</span>
{% if page_obj.has_next %}
next
{% endif %}
</span>
</div>
The standard name for the page query parameter is 'page' You should either change the name of the queryparameter, or render the template with the ?page= parameter.
Option 1: Changing the page_kwarg
You can change that by altering the page_kwarg attribute [Django-doc]:
class HomePageView(ListView):
model = City
template_name = 'cities/home.html'
paginate_by = 3
page_kwarg = 'city'
Option 2: Changing the template
It might be more sensical however to simply change the template, such that it uses page as parameter:
<div class="pagination">
<span class="page-links">
{% if page_obj.has_previous %}
previous
{% endif %}
<span class="page-current">
Page {{ page_obj.number }} of {{ page_obj.paginator.num_pages }}.
</span>
{% if page_obj.has_next %}
next
{% endif %}
</span>
</div>

Can I anyone please help me where I got wrong or what I need to, I just got stuck on this. Initially, it was working fine when I click New post on nav bar, it would lead me to the form when I can input text and author but now when I click there, I get this NoReverseMatch at /post/new/ Reverse for 'post_publish' with keyword arguments '{'pk': ''}' not found.
Thank you.
My first guess is that post object is null here:
<a class = 'btn btn-primary' href=" {% url 'post_publish' pk=post.pk
%}">Publish</a>
But to be sure we need a full stack strace.
EDIT #1
We are still missing the traceback, i cannot see it in your picture, but my answer is still valid. post.pk is None, you should replace it with object.pk since you're using a Detailview.

Django: return form data on the same page

How can I add "headers" to context so it's accessible in templates. I guess it needs to be pass to get request somehow? What would be the pythonic way to pass this variable to a get method in FormView class?
views.py
class IndexView(FormView):
template_name = 'index.html'
form_class = CheckForm
success_url = reverse_lazy('index')
def form_valid(self, form, **kwargs):
context = self.get_context_data(**kwargs)
context['headers'] = form.result()
return super(IndexView, self).form_valid(form)
index.html
<form action="." method="post" name="url" id="url" novalidate>
{{ form.as_p }}
{% csrf_token %}
<button type="submit">Check</button>
{% if headers %}
{% for k,v in headers %}
{{ k }}: {{ v }}<br>
{% endfor %}
{% else %}
<br>No data
{% endif %}
forms.py
from django import forms
import requests
class CheckForm(forms.Form):
url = forms.URLField(max_length=255, label='')
def result(self):
cd = self.cleaned_data
url = cd['url']
r = requests.get(url)
r.headers
return r
urls.py
urlpatterns = [
url(r'^$', views.IndexView.as_view(), name='index'),
]
I am pretty sure you want to use messages
from django.contrib import messages
So now you can add some stuff and send it to the next template.
messages.success(request, u"Success message - text only")
In template :
{% if messages %}
<ul class="messages">
{% for message in messages %}
<li{% if message.tags %} class="{{ message.tags }}"{% endif %}>
{% if message.level == DEFAULT_MESSAGE_LEVELS.ERROR %}Important: {% endif %}
{{ message }}
</li>
{% endfor %}
</ul>
{% endif %}
Main problem is the redirect on success. This will throw another get request to same window. In your case this is not desired as you want to capitalize on the data from the form.
views.py
import requests
class IndexView(FormView):
template_name = 'index.html'
form_class = CheckForm
def form_valid(self, form, **kwargs):
context = self.get_context_data()
context['headers'] = form.get_headers()
return self.render_to_response(context)
forms.py
import requests
from django import forms
class CheckForm(forms.Form):
url = forms.URLField(max_length=255, label='')
def get_headers(self):
if self.cleaned_data:
url = self.cleaned_data['url']
return requests.get(url).headers

index.html

Had a similar requirement and passed the custom context (here a processed file) and the original form instance in form_valid() to a render method instead of the forms default HttpResponseRedirect.
# forms.py
class MyForm(forms.Form):
file = forms.FileField()
# views.py
class MyFormView(FormView):
template_name = 'path/to/template/mytemplate.html'
form_class = MyForm
def get_success_url(self):
return self.request.path
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
context['processed_data'] = None
return context
def do_some_processing(self, file):
# process file...
return processed_data
def form_valid(self, form):
form = super().form_valid(form)
custom_context = {
"form": self.form_class,
"processed_data": self.do_some_processing(self.request.FILES['file']),
}
context = self.get_context_data(form=form)
context.update(custom_context)
return render(self.request, self.template_name, context)
# mytemplate.html
<form method="POST" enctype="multipart/form-data">
{% csrf_token %}
{{ form.as_p }}
<button type="submit">Submit</button>
</form>
<pre>
{{ processed_data }}
</pre>

Django dynamic homepage

I have a lots of apps, but I want to generate all app's data on my homepage. Here's my apps:blog,members
I want to show blogs and my members on my homepage
I know that if I want to generate one app's data,I can do this:
blog/urls.py:
urlpatterns = [
url(r'^$', ListView.as_view(
queryset=Post.objects.all().order_by("-date")[:10],
template_name='blog1.html')),
and in blog1.html:
{% extends "index.html" %}
{% block blog %}
{% for post in blog_post %}
<div id="blog-wrapper" class="bgrid-third s-bgrid-half mob-bgrid-whole group">
<article class="bgrid">
<h5>{{ post.date }} </h5>
<h3><div class = "entry-title">{{ post.title }}</div></h3>
<p>{{ post.user }}</p>
<p><div class = "post_body">{{ post.body|safe|linebreaks }}</div></p>
</article>
</div>
{% endfor %}
{% endblock %}
{% block member %}
Here when I go to the url,I can see all blogs I write,but now I want to see blogs and members(another app) on one page, so how can I do this?
I would suggest you to use ListView's get_context_data method.
Create view in your project's views.py:
from django.views.generic import ListView
# Import your models here.
class HomepageView(ListView):
model = Post
ordering = '-date'
template_name = 'blog1.html'
context_object_name = 'posts'
def get_context_data(self, **kwargs):
context = super(HomepageView, self).get_context_data(**kwargs)
context['members'] = Member.objects.all()
return context
def get_queryset(self):
return super(HomepageView, self).get_queryset()[:10]
Then, change urls.py:
from django.conf.urls import url
# Import ``HomepageView`` here.
urlpatterns = [
url(r'^$', HomepageView.as_view(), name='homepage'),
# Other patterns here.
]
Now you can access posts using posts variable and members using members variable.
from .models import Post
from member.models import UserProfile
def get_data():
return {
"post": Post.objects.all().order_by("-date")[:10],
"user": UserProfile.objects.all()[:10]
}
then in my blog1.html:
{% extends "index.html" %}
{% block blog %}
{% for post in object_list.post %}
<div id="blog-wrapper" class="bgrid-third s-bgrid-half mob-bgrid-whole group">
<article class="bgrid">
<h5>{{ post.date }} </h5>
<h3><div class = "entry-title">{{ post.title }}</div></h3>
<p>{{ post.user }}</p>
<p><div class = "post_body">{{ post.body|safe|linebreaks }}</div></p>
</article>
</div>
{% endfor %}
{% endblock %}
{% block member %}
{% for post in object_list.user %}
<div class="bgrid member">
<div class="member-header">
<div class="member-pic">
<img src="{{ post.portrait }}" alt=""/>
</div>
<div class="member-name">
<h3>{{ post.user }}</h3>
<span>Creative Director</span>
</div>
</div>
<p>{{ post.intro }}</p>
<ul class="member-social">
<li><i class="fa fa-google-plus"></i></li>
<li><i class="fa fa-github"></i></li>
</ul>
</div> <!-- /member -->
{% endfor %}
{% endblock %}
