Hello everyone:) Links that I have in 'navbar' overlaps each other when I make a transition into another link. For instance, I have a navbar menu with four different links (home, catalog, distributors and contacts) and 'home' is a base webpage. I.e when I make a transition from the base webpage 'http://127.0.0.1:8000/' to catalog I get this http://127.0.0.1:8000/catalog (all right) but then I make a transition into section 'distributors' and then I get this 'http://127.0.0.1:8000/catalog/distributors (and it's not normal) How to rectify this?
My url patterns seems right :/
urlpatterns = [
url(r'^$', views.home, name='home'),
url(r'^catalog/$', views.catalog, name='catalog'),
url(r'^distributors/$', views.distributors, name='distributors'),
url(r'^contacts/$', views.contacts, name='Contacts'),
]

Can someone help me with this problem? Django version 1.11.2
As #David D. answered, you should use the method of url building as it provides you flexibility.
But, if for some reason you want that absolute URLs should be specified in href, then while using absolute urls the above problem can be solved by prepending a forward slash to each url name when assigning to href.
So your new urls should look like :
CATALOG
DISTRIBUTORS
CONTACTS
The reason it works is that / represents root of website, so using '/' routes you to the root and using '/catalog' routes you to the catalog page directly from the root.
The problem is the way you use links in your Django templates.
Take a look to: https://docs.djangoproject.com/en/2.0/ref/templates/builtins/#url
You have to use a {% url 'url-name-here' %} sothat Django will build url by itself.
For example, in your case:
<div class="image"><p>CATALOG</p></div>
This way:
it's a lot easier for you, you just provide the url name and let Django generated the real url.
you don't repeat yourself; if you want to change the path of the url, you only need to do it one time in urls.py.

I have aproblem when i try to render the JSON data in the HTML template.
I dont know if the problem is in the Python code or in the HTML code.
I've tested the python code of the search funtion (returns a JSON with a list o products) and returns a valid JSON (the JSON than i expected).
But i still havig issues with the HTML.
I've searched a lot, but nothing helped me.
The function of the HTML template is to display the products of my ecommerce. In this template i'll show the results of a previous search.
Here is the code of the python app:
search = request.form['search']
if search != "":
for product in mycol.find({"name": {"$regex": f".*{search}.*", "$options": "i"}}):
datainfo = json.loads(json_util.dumps(product))
return render_template("search.html", product=datainfo)
else:
return render_template("index.html")
The HTML card code:
<div>
<div class="results_container">
<div class="row">
<div class="card">
<ul>
{% for product in product %}
<li class="table-row">
<div id="Product">{{product['name']}}</div>
<div id="Price">{{product['price']}}</div>
<div id="Description">{{product['description']}}</div>
<div id="Category">{{product['category']}}</div>
<div id="Seller">{{product['user_name']}}</div>
<div>
Buy
</div>
</li>
{% endfor %}
</ul>
</div>
</div>
</div>
</div>

I have a lot of html pages that are formatted differently but the content that interests me is the same , for example :
Page_1.html :
<div class = "block_person">
<div class="persons"><span>Jules Rodrigez</span></div>
<div class="contents"><h1>Jules Rodrigez is a programmer specialized in machine learning</h1></div>
</div>
<div class = "block_person">
<div class="persons"><span>James Alfonso</span></div>
<div class="contents"><h1>James is a singer</h1></div>
</div>
page_2.html :
<div class="many_speakers" >
<div class="speakers"><h1>Jules Rodrigez</h1></div>
<div class="summary"><span>Jules Rodrigez is a programmer specialized in data science</span></div>
</div>
<div class="many_speakers" >
<div class="speakers"><h1>Peka Yaya</h1></div>
<div class="summary"><span>Peka is a professor</span></div>
</div>
<div class="many_speakers" >
<div class="speakers"><h1>Cristiano dimaria</h1></div>
<div class="summary"><span>Cristiano is a football player</span></div>
</div>
from a page html (page_1 or page_2), i want to get a list of objects like :
from page_1.html
[{"person":"Jules Rodrigez","content":"Jules Rodrigez is a programmer specialized in machine learning"},{"person":"James Alfonso","content":"James is a singer"}]
the problem is that each page is formatted with an structure : how can we detect in an html page that a block is repeated several times and therefore it contains the requested information : for example in the page_1.html the bloc which is repeated several times is :
<div class = "block_person">
<div class="persons"><span>Jules Rodrigez</span></div>
<div class="contents"><h1>Jules Rodrigez is a programmer specialized in machine learning</h1></div>
</div>
I have set up Django templates, which include index.html, header.html and footer.html.
In footer.html, I want to set dynamically a phone number, email and address. I can see I can pass it through context from views.py, but footer.html will included in all the templates, so I will need to pass it in every function in views.py, which is not good.
So what I want is to create one common function and I want to call it from footer.html. Is that the right way to do this? Or if you have any other idea, then please let me know how to do that.
views.py:
def index(request):
portal_contact_email = preferences.MyPreferences.portal_contact_email
context = {'portal_contact_email': portal_contact_email,}
return render(request, 'mysite/index.html', context)
footer.html:
<footer class="bg-dark footer-section">
<div class="section">
<div class="container">
<div class="row">
<div class="col-md-4">
<h5 class="text-light">Email</h5>
<p class="text-white paragraph-lg font-secondary">{{ portal_contact_email }} </p>
</div>
<div class="col-md-4">
<h5 class="text-light">Phone</h5>
<p class="text-white paragraph-lg font-secondary"></p>
</div>
<div class="col-md-4">
<h5 class="text-light">Address</h5>
<p class="text-white paragraph-lg font-secondary"></p>
</div>
</div>
</div>
</div>
<div class="border-top text-center border-dark py-5">
<p class="mb-0 text-light">Copyright #<script>
var CurrentYear = new Date().getFullYear()
document.write(CurrentYear)
</script>
{# a theme by themefisher.com#}
</p>
</div>
</footer>
For this purpose you could create a custom ContextProcessor.
According to the docs, ContextProcessors
take a request object as their argument and return a dictionary of items to be merged into the context
A custom ContextProcessor in your case could look like this:
def footer_data(request):
return {'phone_number': 'xyz', ...}
Then append it to your settings.py so it is actually being used:
TEMPLATES = [
{
...
'OPTIONS': {
'context_processors': [
'myapp.my_context_processors.footer_data',
...
And in your templates you can access these variables simply with {{ phone_numer }}.

The above code is the front end part HTML here I want to pass a parameter into the urls.py by clicking a box and depends on the parameter which we pass the data should be fetched.
urls.py
url(r'^list_of_employees/<string>/$', views.Pay_slip_list , name='emp_pay_list'),
This is the code which I am using in urls.py to pass parameter.
views.py
def Pay_slip_list(request, department):
hello = employees.objects.select_related('employee_name', 'employee_auth').filter(department=department)
return render(request, 'hr/emp_pay_list.html', {'hello': hello})
And this is the views.py part where I am fetching data from the database based on the string/parameter passed after clicking the box.
Your URL pattern must look like
from django.urls import path, re_path
path('list_of_employees/<str:department>/', views.Pay_slip_list , name='emp_pay_list'),
or use re_path
re_path(r'^list_of_employees/(?P<department>[\w\-]+)/$', views.Pay_slip_list , name='emp_pay_list')
use path instead of url for Django version >= 2.0, or use re_path for complex patterns, re_path is same as url method in lower versions
I am trying to send data from django views.py file to angularjs controller.js file but unable to send it.
The problem is this that I am unable to send data from views file to controller. And when I run my code then the value {%steps%} doesn't change to the value I have assigned in views file.
I don't want to use Django rest framework for doing this.
Is there any other way of achieving this? If yes, then please help me out.
views.py:
from django.shortcuts import render
from django.conf import settings
from user_data.models import GetData
import json
def home(req):
return render(req, 'index.html')
def userData(req):
if req.method == 'GET':
user_data = GetData().getAllData()
context_dict = {'user_data1' : json.dumps(user_data[0]),
'user_data2' : json.dumps(user_data[1]),
'user_steps' : json.dumps(2000)}
return render(req, 'index.html', context_dict)
controller.js :
'use strict';
MetronicApp.controller('DashboardController', function($rootScope, $scope, $http, $timeout) {
$scope.$on('$viewContentLoaded', function() {
// initialize core components
Metronic.initAjax();
});
$scope.steps = {{user_steps|safe}};

This is basically what I have done in one of my major django projects (but I am not 100% sure, whether this is or this ain't what you are looking for, as an answer).
So, instead of views.py, I have made a custom.py file in which I make custom APIs and call them (using urlpatterns) in the urls.py of my django app. And I have another set of APIs for which I am using django rest framework, for which I make viewsets rather than simple views. Just in case, you are interested, you might like reading this SO link.
But since, you specifically mentioned that you don't want to use django rest frameworks, I will give you an example of the custom.py file, as mentioned above.
Below you will find a sample of an API defined in a custom.py,
#api_view(['GET'])
def get_user_details(request):
"""
API View that gives a user detail
---
parameters:
- name: email
description: The email of the user based on which his/her information has been extracted
required: true
type: string
responseMessages:
- code: 400
message: Email required as GET parameters.
message: User not found.
- code: 200
mesage: User details sent successfully
consumes:
- application/json
- application/xml
produces:
- application/json
- application/xml
"""
email = request.query_params.get('email', None)
if email is None:
return HttpResponseBadRequest("Email required as GET parameters.")
try:
user = User.objects.get(username=email)
except User.DoesNotExist:
return HttpResponseBadRequest("User not found.")
response_data = {'id': user.id, 'first_name': user.first_name, 'last_name': user.last_name,}
return HttpResponse(json.dumps(response_data), content_type="application/json")
And subsequently, the urls.py in my django app looks like:
urlpatterns = router.urls
urlpatterns = urlpatterns + [
url(r'get_user_details/', get_user_details),
]
My controller would look something like this:
CheckEmail : function (current) {
return $http({
method: 'GET',
url: baseAPI + 'admin/get_user_details/',
params: {email: current},
})
},
And then subsequently, you may be able to render the variable you wish to print in your html file using handles.
Hope, it helps.
