Why can't select one object in django

I'm creating a ecommerce store using django And tried s many things to do this.index page is working pretty well but I want select specific product when I click .ex: when I click a shoe I want to enter shoe detail page with shoe image and all the necessary details.Here is my home page.And also I highly recommend to check my all code because you can't get any idea with only this code.github source code here.thanks dinindu
{% extends 'store/main.html'%}
{% load static %}
{% block content %}
<style>
img:hover{
opacity: 0.5;
}
</style>
<div class="row">
{% for product in products %}
<div class="col-lg-4">
<a href="{% url 'productDetail' Product.name %}"><img
class="thumbnail" src="{{product.imageURL}}"></a>
<div class="box-element product">
<h6><strong>{{product.name}}</strong></h6>
<hr>
<button data-product="{{product.id}}" data-action="add"
class="btn btn-outline-secondary add-btn update-cart">Add to
Cart</button>
<h4 style="display: inline-block; float:
right"><strong>Rs {{product.price}}</strong></h4>
</div>
</div>
{% endfor %}
</div>
{% endblock content %}

you could do something like this, an adapt it to your project:
Views:
def product_list(request):
products = Product.objects.all()
return render(request,'list.html',{'products': products})
def product_detail(request, id):
product = Product.objects.get(id=id)
return render(request,'detail.html',{'product': product,})
urls:
path('products/', views.product_list, name='product_list'),
path('products/<int:id>/', views.product_detail, name='product_detail')
templates
list.html
{% for product in products %}
<div>
<a href="{% url 'product_detail' product.id %}">
<img src="{ product.image.url }}">
</a>
{{ product.name }}
</div>
{% endfor %}
detail.html
<div>
<img src="{{ product.image.url }}">
<h2>{{ product.name }}</h2>
<h3>{{ product.price }}</h3>
<h4>{{ product.digital }}</h4>
</div>

Changing the size of bootstrap cards in a Django project?

I'm working on a simple Django project with bootstrap. I have a set of cards being displayed on a page, and the cards are showing just fine (Don't mind the place holder images).
I've been reading the bootstrap docs about cards, but since I have less knowledge of CSS than I'd like, I can't figure out how to simply change the size of the cards so they are larger and stacked in rows instead of one column.
This is my HTML template for this page. It just uses a for-loop to go through my projects and make a card for each. You can see I have the title and text worked out, and the URL to 'See Details'.
{% extends "base.html" %}
{% load static %}
{% block page_content %}
<h1>Projects</h1>
<div class="row">
{% for project in projects %}
<div class="col-md-4">
<div class="card mb-2">
<img class="card-img-top" src="{% static project.image %}">
<div class="card-body">
<h5 class="card-title">{{ project.title }}</h5>
<p class="card-text">{{ project.description }}</p>
<a href="{% url 'project_detail' project.pk %}"
class="btn btn-primary">
See Details
</a>
</div>
</div>
</div>
{% endfor %}
</div>
{% endblock %}
The Base.html is just linking to the bootstrap and all the html for the top of the page. Hopefully the fix is a really simple addition to the template, but I haven't had much luck finding info.

You can use row to create grid row for each card object, and remove the col div.
{% extends "base.html" %}
{% load static %}
{% block page_content %}
<h1>Projects</h1>
{% for project in projects %}
<div class="row">
<div class="card mb-2">
<img class="card-img-top" src="{% static project.image %}">
<div class="card-body">
<h5 class="card-title">{{ project.title }}</h5>
<p class="card-text">{{ project.description }}</p>
<a href="{% url 'project_detail' project.pk %}"
class="btn btn-primary">
See Details
</a>
</div>
</div>
</div>
{% endfor %}
{% endblock %}

I want to create a website where users will be posting to the site, How would I make each post appear in a separate card?

Am creating a website where user will be posting information in the site, but when I post in the site, all post appear in a single card while I want each post to appear in a separate card, How would I do this?? would I have to use Javascript in the front end or python in the back end to accomplish this, and how?
Am using python 3.6.8, and django 2.1.8, I have written a code but all post appear in single materialize card
views
def homepage(request):
return render(request=request,
template_name="main/home.html",
context={"documents":Documents.objects.all}
models
class Documents(models.Model):
docs_name = models.CharField(max_length=200)
police_station = models.CharField(max_length=200)
docs_details = models.TextField()
docs_pic = models.ImageField()
def __str__(self):
return self.docs_name
Home template
{% extends 'main/base.html' %}
{% block content %}
<a class="waves-effect waves-light btn" href="">button</a>
<div class="row">
<div class="col s12 m9" >
<div class="card">
<div class="card-image">
{% for Doc in documents %}
<p>{{Doc.docs_name}}</p>
<p>{{Doc.police_station}}</p>
<p>{{Doc.docs_details}}</p>
<p>{{Doc.docs_pic}}</p>
{% endfor %}
</div>
</div>
</div>
</div>
{% endblock %}

Try:
{% extends 'main/base.html' %}
{% block content %}
<a class="waves-effect waves-light btn" href="">button</a>
<div class="row">
<div class="col s12 m9" >
{% for Doc in documents %}
<div class="card">
<div class="card-image">
<p>{{Doc.docs_name}}</p>
<p>{{Doc.police_station}}</p>
<p>{{Doc.docs_details}}</p>
<p>{{Doc.docs_pic}}</p>
</div>
</div>
{% endfor %}
</div>
</div>
{% endblock %}

You can achieve what you desire by simply adding the looping construct outside the <div class="card"> like this :
{% extends 'main/base.html' %}
{% block content %}
<a class="waves-effect waves-light btn" href="">button</a>
<div class="row">
<div class="col s12 m9" >
{% for Doc in documents %}
<div class="card">
<div class="card-image">
<p>{{Doc.docs_name}}</p>
<p>{{Doc.police_station}}</p>
<p>{{Doc.docs_details}}</p>
<p>{{Doc.docs_pic}}</p>
</div>
</div>
{% endfor %}
</div>
</div>
{% endblock %}
This way your card section alone repeats multiple times.
Earlier since the loop was within the card you got all the items within the same card.

Can't display database data in Django

I am working on library website in which I want to display data from database which is Book name and description. But I'm not able to do that. Here is my code
views.py
from django.shortcuts import render
from .models import *
def index(request):
book_list = Book.objects.all()
return render(request,template_name='index.html', context={'book_list':book_list})
index.html
{% extends "base_generic.html" %}
{% block new_books %}
{% for b in book_list %}
<div class="card">
<img class="card-img-top" src=".." alt="Image">
<div class="card-body">
<h5 class="card-title">{{ book_list }} </h5>
<p class="card-text">Hello this is card text</p>
<a class="btn btn-primary">View this book</a>
</div>
</div>
{% endfor %}
{% endblock %}

You should work with b variable instead of book_list inside of for loop.
If your Book model contains title field, your code might look like this:
{% extends "base_generic.html" %}
{% block new_books %}
{% for b in book_list %}
<div class="card">
<img class="card-img-top" src=".." alt="Image">
<div class="card-body">
<h5 class="card-title">{{ b.title }} </h5>
<p class="card-text">Hello this is card text</p>
<a class="btn btn-primary">View this book</a>
</div>
</div>
{% endfor %}
{% endblock %}

Safari not displaying some of my content

so i have an issue where everything works as it should in chrome but in safari some things are just not displayed as if they weren't there.
in my nav it should have products, about, contact and blog in chrome it displays as such, but in safari the contact link is missing. when i checked the inspector its not even hidden its just not in the code.
and one of my filters on the product page again works fine in chrome but in safari the indiviudals tab just doesn't display any content and the medical schools tab is missing one of its items.
product page
<section class="resource-list-block content-block">
<div class="product-overview col-sm-offset-1 col-sm-10 col-xl-offset-1 col-xl-10 resource-list-block__list">
{% for product_page in product_pages %}
{% if product_page.get_content_model.public %}
<div class="col-sm-6 col-md-4 col-xl-4 cover resource-list-block__list__item resource-list-block__list__item--important filterable product-list-block__list__item filtered-cat filtered-filt" data-category="{{ product_page.get_content_model.specialties.all|specialties }}" data-filter="{{ product_page.get_content_model.tags.all|tags }}">
<a href="{{product_page.get_absolute_url}}">
{% include "includes/product-cover.html" with product=product_page.get_content_model.product %}
</a>
</div>
{% endif %}
{% endfor %}
</div>
product-item section
{% load staticfiles compress %}<div class="sans-serif cover-page">
<figure class="figure-cover" style="background-color:#{{product.theme_color}} !important;">
<div class="cover-img center-block"><img src="{{product.element_icon.url}}" class="img-responsive center-block" alt="{{product.title}} Image"></div>
<div class="product-count">
<div class="text-center"><i class="fa fa-calendar"></i><span class="small-text"> {{ product.updates_per_year }} updates per year</span></div>
</div>
<div class="clearfix"></div>
<div class="text-center type-name">
<h3 class="sans-serif">{{ product_page.get_content_model.product_type | upper }}</h3>
<h4 class="sans-serif hidden-md hidden-sm hidden-xs">{{ product_page.get_content_model.editor_text }} <br> {{ product_page.get_content_model.editor_title_text }}</h4>
<h4 class="sans-serif">ISSN {{ product.issn }}</h4>
</div>
</figure>
<figure class="product-content" {% if product.theme_color = 'AF1F24' %} style="background-color:#f2e4e5 !important" {% endif%}>
<div class="cover-img center-block"><img src="{{product.element_icon_alt.url}}" class="img-responsive center-block" alt="{{product.title}} Image"></div>
<div class="clearfix"></div>
<h2 class="text-center type-name">{{ product.title | upper }}</h2>
<figcaption>
<p>{{ product_page.get_content_model.intro }}</p>
</figcaption>
</figure>
and the nav code
{% load pages_tags i18n future %}{% spaceless %}<ul class="decker-menu generic-nav-list generic-nav-list--horizontal theme" id="hero-nav">
{% for child_page in page_branch %}
{% if child_page.in_menu %}
<li class="decker-menu__item">
<a {% if child_page == page or child_page in page.get_ascendants %} class="active important" {% endif %} href="{% if child_page.slug|slice:":4" == 'http' %}{{ child_page.slug }}{% else %} {{ child_page.get_absolute_url }}{% endif %}" >{{ child_page.title }}</a>
</li>
{% endif %}
{% endfor %}<li class="decker-menu__item login-btn"><a href="#">Menu</li></ul>{% endspaceless %}

had to go into mezzanine on safari then remove the content save and refresh the page then go back and re-add it to fix the issue. then repeated that step to fix the issue in firefox.... so weird
thanks!
