I'm using mongodb and django, so I decided to utilize djongo as the connector - djongo doc - that been said I'm trying to display the content I find on querys in django templates - busca.html - but I can't find a way to display the Embedded models.
busca.html
{% extends 'app/base.html' %}
{% block cabecalho %}
{% load staticfiles %}
<title>SDF{{ numero }}</title>
{% endblock%}
{% block conteudo %}
<section class="bg-light">
<div class="container ">
<div class="col-lg-12 h-100 text-center text-lg-left my-auto">
<h1 class="text-muted medium mb-4 mb-lg-0">SDF{{ numero }</h1>
<br>
{{ sdf }}
</div>
</div>
</section>
{% endblock %}
Doing that only display the number - 'numero' - of the sdf.
Thanks.
{{ sdf }} calls the __str__ method of your model, which returns numero as defined. To display all the fields use {{ sdf.numero }}, {{ sdf.decomposicao }}, {{ sdf.data_insercao }}. I believe that you could access fields of your embedded model with dot notation, for example {{ sdf.decomposicao.tirosina }}.

am new to Django and am trying to create a blog site where users can sign up and post articles, but my problem is how can I display a user's post on the user's profile page so that when other users reading the post clicks on the author's name it takes them to the post.author's profile page with the post.author's recent post listed and not the request.user's post. here is my code.
here is accounts/views.py
views.py
#login_required()
def user_profile_view(request, username):
post = User.objects.filter(courses__author=username)
context = {'courses': courses}
return render(request, 'accounts/user_profile_view.html', context)
and here is post/models.py
models.py
class Posts(models.Model):
author = models.ForeignKey(User, on_delete=models.CASCADE)
cover = ProcessedImageField(upload_to='post_featured_image',
processors=[ResizeToFill(600, 300)],
format='png',
options={'quality': 80},
blank=True)
slug = models.SlugField()
title = models.CharField(max_length=200)
body = models.TextField()
summary = models.TextField(max_length=200)
here is the template
post_list.html
{% extends 'base.html' %}
{% load static %}
{% block content %}
<div class="col-lg-6">
{% for course in courses_list %}
<div class="central-meta item">
<div class="user-post">
<div class="friend-info">
{% if post.author.profile.avatar %}

{% else %}
<img src="{% static 'default.ico' %}" alt="">
{% endif %}
<div class="friend-name">

<p><span>{{ post.summary|capfirst }}</span></p>
</div>
</div>
</div>
</div>
</div>
{% endfor %}
</div>
{% endblock content %}
here is my accounts/urls.py
urls.py
app_name = 'accounts'
urlpatterns = [
path('accounts/profile/<str:username>/', user_profile_view, name='user_profile'),
]
you should be able do that, easy and via lots of ways.
make a post model like this:
class Post(models.Model):
author = foreign_key(User, related_name="posts", on_delete=models.CASCADE)
title = char_field()
content ........
so with that related name you will be able to reverse from user to its posts too!.
in your template do this:
{{ post.author }}
this link will redirect user to the posts author dashboard if you arrange the urls pattern correctly.
then for sorting authors posts, you have to pass the dashboard_owner to the template and use this name instead of user which normally will refer to the request.user -> user who are visiting the page
{% for post in dash_owner.posts.all %}
<li> <a href="{{ post.get_abslute_url }}" target="_blink">
{{ post.title }} </a> </li>
{% endfor %}
in views.py
def dashboard(request, owner_id=None)
if owner_id:
dash_owner = get_or_404(User, id=owner_id)
elif request.user.is_authenticated:
dash_owner = User.objectd.get(id=request.user.id)
return render(request, 'dashboard.html', {'dash_owner': dash_owner})
in urls.py -> urlpatterns:
path('dashboard/<int:owner_id>/', views.dashboard, name="dashboard")
this is the idea behind that, but for get the better result, you may need to clearly define the get_absolute_url of User model, to give you the url which machts to
'dashboard/<int:id/'
or another way is instead of that, do this:
{{ post.author }}
I am struggling to see a way to style a django form in the style of a uikit horizontal form. UIKit has the styling I want and Django has the validation and templating I want.A way to implement a datepicker too would be useful.
I have tried the plain django form template with .as_p and .as_table. I have also tried to use Meta and widgets but couldn't get that to work. I can't see how I can add the needed uikit tags to each element and add the uk-form-controls div.
template.html
<form class="uk-form-horizontal uk-margin-large uk-align-center">
<div class="uk-margin">
<label class="uk-form-label" for="form-horizontal-text">Job Title</label>
<div class="uk-form-controls">
<input class="uk-input uk-form-width-large" id="form-horizontal-text" type="text" placeholder="Some text...">
</div>
</div>
forms.py
class job_form(forms.Form):
job_title = forms.CharField(label='Job Title', max_length=50)
hiring_manager = forms.CharField(label='Hiring Manager', max_length=50)
job_description = forms.CharField(label='Job Description', max_length=50)
salary = forms.IntegerField()
closing_date = forms.DateField()
I am expecting to be able to have the uikit form styling with the templating and validation of django forms but am yet to get it to work.
Django has a variety of ways to override the form behavior and layout. I see you are using forms.Form instance. Simply add your classes to the form class like:
class NiceForm(forms.Form):
solid_field=forms.CharField(widget=forms.TextInput(attrs={'class': 'uk-form-input'}))
Although it is simple, but sluggish, when you want introduce breaking changes to the layout, I would override the template (or render method if you like) to bundle a reusable widget. Simple example to extract the form to external reusable template as you can render them manually as HTML like documentation.
Leave the form clean and use templatetag to override classes:
# _form_icludes.html
{% for field in form.visible_fields %}
<fieldset class="uk-fieldset">
<div class="uk-margin">
<label class="uk-form-label" for="{{ field.id_for_label }}">{{ field.label }}</label>
<div class="uk-form-controls">
{% if field.field.widget.input_type == 'select' %}
{{ field | add_css_cls:'uk-select'}}
{% elif field.field.widget.input_type == 'option'%}
{{ field | add_css_cls:'uk-option'}}
{% elif field.field.widget.input_type == 'checkbox'%}
{{ field | add_css_cls:'uk-checkbox'}}
{% elif field.field.widget.input_type == 'select'%}
{{ field | add_css_cls:'uk-select'}}
{% elif field.field.widget.input_type == 'file'%}
{{ field }}
{% else %}
{{ field | add_css_cls:'uk-input'}}
{% endif %}
{% if field.help_text %}
<span class="uk-text-small uk-text-left uk-text-italic">
{{ field.help_text }}
</span>
{% endif %}
{% if field.errors %}
{% for error in field.errors %}
<p class="uk-flex uk-flex-middle uk-text-danger ">
<span data-uk-icon="icon:warning" class="uk-text-danger uk-margin-small-right"></span>
{{ error | escape }}
<p/>
</div>
{% endfor %}
{% endif %}
</div>
</fieldset>
{% endfor %}
# add_css_cls
from django import template
register = template.Library()
#register.filter
def add_css_cls(value, arg):
css_classes = value.field.widget.attrs.get('class', '').split(' ')
if css_classes and arg not in css_classes:
css_classes = '%s %s' % (css_classes, arg)
return value.as_widget(attrs={'class': css_classes})
There are many different ways.
I have a ModelForm that posts news items to a database, and it uses a javascript textarea to allow the authorized poster to insert certain pieces of HTML to style text, like bold and italics. However, since I have the template output using the "safe" filter, it outputs all the HTML the form widget tries to pass on. This includes a bothersome <br> tag that never goes away, making it so you can submit without form validation reading the field as empty and stopping you. How can I make that I can not only filter the <br> tag, but completely remove it from the data? Here is relevant code:
Models.py:
from django.db import models
from django.forms import ModelForm, forms
from django.contrib.auth.models import User
# Create your models here.
class NewsItem(models.Model):
user = models.ForeignKey(User)
date = models.DateField(auto_now=True)
news = models.TextField(max_length=100000, blank=False, help_text='HELP TEXT')
def __unicode__(self):
return u'%s %s %s' % (self.user, self.date, self.news)
class NewsForm(ModelForm):
class Meta:
model = NewsItem
exclude=('user','date',)
Views.py:
from news.models import NewsForm, NewsItem
from django.shortcuts import render
from django.http import HttpResponseRedirect, HttpResponse
def news(request):
if request.method == 'POST':
item = NewsItem(user=request.user)
form = NewsForm(request.POST, instance=item)
if form.is_valid():
form.save()
return HttpResponseRedirect('/news/')
else:
form = NewsForm()
news_list = NewsItem.objects.all()
return render(request, 'news_list.html', {'news_list': news_list, 'form': form})
news_list.html:
{% extends "base.html" %}
{% block title %}News in the Corps{% endblock %}
{% block content %}
<h2 id="page_h">News in the Corps</h2>
{% if user.is_authenticated %}
<h3>Post News</h3>
<script src="{{ STATIC_URL }}nicEdit.js" type="text/javascript"></script>
<script type="text/javascript">bkLib.onDomLoaded(nicEditors.allTextAreas);</script>
<div id="news_poster">
<form id="news_poster" action="/news/" method="POST">{% csrf_token %}
{{ form }}
<input type="submit" value="Submit" />
</form>
</div>
{% endif %}
<ul id="events_list">
{% if news_list %}
<div id="news_list">
{% for news in news_list %}
{% if news.id == 1 %}
<hr />
{% endif %}
<div id="{{ news.id }}" class="news_item">
<p class="poster">Posted By: {{ news.user }} | Posted On: {{ news.date }} | Link</p>
<div id="news_item">
{{ news.news|safe }}
</div>
</div>
<hr />
{% endfor %}
</div>
{% endif %}
</ul>
{% endblock %}
You can try the removetags template filter:
{{ news.news|removetags:"br"|safe }}
I can't help but thinking that the "removetags" as Timmy O'Mahony suggested might work if it was structured like this:
{{ news.news|safe|removetags:"br"}}
Give it a shot and see if it works. I would reply, but my karma's not height enough to directly reply to an answer with a suggestion.
Wanted effect is passing the id to the request handler and populating the form with that entity. How doable is it with a template? Here are my form, request handler and template
class AForm(djangoforms.ModelForm):
text = forms.CharField(widget=forms.Textarea(attrs={'rows':'11','cols':'70','class':'foo'}),label=_("content").capitalize())
class Meta:
model = A
fields = ['category','currency','price','title','phonenumber','postaladress','name','text','email'] #change the order
class FileUploadFormHandler(I18NHandler):
def get(self):
cookie_django_language = self.request.get('hl', '')
if cookie_django_language:
if cookie_django_language == 'unset':
del self.request.COOKIES['django_language']
else:
self.request.COOKIES['django_language'] = cookie_django_language
translation.activate(cookie_django_language)
self.render_template("upload.html", {
'form': AForm(),
'form_url': blobstore.create_upload_url('/fileupload'),
'logout_url': users.create_logout_url('/'),
})
<table>
{% for field in form %}
<tr><td>
<div class="fieldWrapper">
{{ form.title.errors }}
<label for="id_subject">{% filter capfirst %}{% trans "headline" %}{% endfilter %}</label></td><td>
{{ form.title }}</td></tr>
</div><tr><td>
<div class="fieldWrapper">
{{ form.category.errors }}
<label for="id_subject">{% filter capfirst %}{% trans "content" %}{% endfilter %}</label></td><td>
You should initialize your form with the entity you want to show:
form = AForm(instance = some_model_instance)
I'm having some trouble using get_absolute_url in a template. It seems to work fine if I just pass in one of my store objects and say {{ store.get_absolute_url }}, but if I have to iterate through a dictionary of stores and then use the get_absolute_url function, it returns nothing. Exactly what I'm doing is below:
class Store(EthicalObject):
type = "Store"
name = models.CharField(max_length=50)
company = models.ForeignKey(Company, verbose_name="Company", null=True, blank=True)
location = models.OneToOneField(Location, verbose_name="Location", null=True, blank=True)
products = models.ManyToManyField('Product', related_name="%(class)s_related", db_table=u'ethicsdb_products_to_stores', blank=True)
companies = models.ManyToManyField('Company', related_name="%(class)s_related", db_table=u'ethicsdb_companies_to_stores', blank=True)
def get_absolute_url(self):
return ('store_details', [str(self.id)])
get_absolute_url = models.permalink(get_absolute_url)
This works:
views.py:
def fetch_sidebar_data(shop_object):
sidebar_modules = {}
if shop_object.content_type.name == 'company':
sidebar_modules['related_stores'] = shop_object.stores.all()
sidebar_modules['related_products'] = shop_object.products.all()
if shop_object.content_type.name == 'store':
sidebar_modules['related_companies'] = shop_object.companies.all()
sidebar_modules['related_products'] = shop_object.products.all()
if shop_object.content_type.name == 'product':
sidebar_modules['related_stores'] = shop_object.stores.all()
sidebar_modules['related_companies'] = shop_object.companies.all()
sidebar_modules['tags'] = shop_object.tags
return sidebar_modules['related_stores'][1]
def company_details(request, company_id):
company = get_object_or_404(Company, id=company_id)
sidebar_modules = fetch_sidebar_data(company)
return render_to_response('company/details.html', {'company': company, 'sidebar_modules': sidebar_modules}, context_instance=RequestContext(request))

{% block sidebar_content %}

This doesn't work:

def fetch_sidebar_data(shop_object):
sidebar_modules = {}
if shop_object.content_type.name == 'company':
sidebar_modules['related_stores'] = shop_object.stores.all()

In the second one, I just get no return from get_absolute_url. I know it's working in other places when I print it out. Is this a Django bug, the inability to use get_absolute_url in a dictionary of dictionaries?
Wow, that was a rather convoluted question.
Your problem is here: {% for related_store in module.values %}
module is a QuerySet. .values is calling the QuerySet method which returns a dictionary containing the field values for each row. A dictionary has no get_absolute_url attribute, and get_absolute_url isn't a field in the model.
Just use {% for related_store in module %} and you'll be dealing with actual model instances rather than dictionaries, which means {{ related_store.get_absolute_url }} will work fine.
