Creating sitemap of Dynamic URLs in your Django Application

A site map can be a hierarchical list of pages, an organization chart, or an XML document that provides instructions to search engine crawl bots.

Why sitemaps are required:

XML Sitemaps are important for SEO because they make it easier for Google to find your site’s pages—this is important because Google ranks web PAGES, not just websites. There is no downside of having an XML Sitemap and having one can improve your SEO, so we highly recommend them.

Example:

The sitemap for this blog can be found at http://thepythondjango.com/sitemap_index.xml .

Steps to add Sitemaps to your Django Application:

Create a file sitemap.py in your app.

Create two different classes in sitemap.py file, one for static pages and another for Dynamic URLs.

Let’s assume your website sell some product where product details are stored in the database. Once a new product is added to the database, you want that product page to be searchable by search engines. We need to add all such product pages/URLs to sitemaps.

Static Sitemap:

Define a class StaticSitemap in your sitemap.py file. Define the mandatory function items in it which will return the list of objects.

These objects will be passed to the location method which will create URL from these objects.

from django.contrib.sitemaps import Sitemap
from django.core.urlresolvers import reverse

class StaticSitemap(Sitemap):

    def items(self):
        return [
            'myapp:terms_and_conditions',
            'myapp:contact_us',
            'myapp:about_us'
        ]

    def location(self, item):
        return reverse(item)

Here in items function, we are returning appname:url_name which will be used by location method to convert into an absolute URL.

Refer you app’s urls.py file for URL names.

Dynamic Sitemap:

Similarly, we will create Dynamic sitemap by fetching values from DB.

from mystore.models import ProductDetailsModel


class ProductSitemap(Sitemap):

    def items(self):
        return ProductDetailsModel.objects.all()

    def location(self, item):
        return reverse('myapp:product', args=[item.product_id])

Here we are getting all products from the database and generating URLs like http:example.com/product/12.

Adding sitemaps in URLconf:

Now add these sitemap class in URLconf. Edit the project’s urls.py file and add below code in it.

from mystore.sitemap import  StaticSitemap, ProductSitemap
from django.contrib.sitemaps.views import sitemap


sitemaps = {
 'pages': StaticSitemap,
 'products': ProductSitemap,
}

urlpatterns += [
    url(r'^sitemap.xml
Now reload your server and go to ```localhost:8000/sitemap.xml``` and you will be able to see your sitemap there.

The only thing to keep in mind while dealing with audio posts is to make sure that you use the external_url parameter or data. You cannot use both at the same time. * caption - a string, the caption for your post * external_url - a string, the url of the site that hosts the audio file * data - a string, the filepath of the audio file you want to upload to Tumblr

#Creating a video post from local file
client.create_video(blogName, caption="testing", data="/Users/johnb/testing/ok/blah.mov")

Editing a post

Updating a post requires you knowing what type a post you're updating. You'll be able to supply to the post any of the options given above for updates.

client.edit_post(blogName, id=post_id, type="text", title="Updated")
client.edit_post(blogName, id=post_id, type="photo", data="/Users/johnb/mega/awesome.jpg")

Reblogging a Post

Reblogging a post just requires knowing the post id and the reblog key, which is supplied in the JSON of any post object.

client.reblog(blogName, id=125356, reblog_key="reblog_key")

Deleting a post

Deleting just requires that you own the post and have the post id

client.delete_post(blogName, 123456) # Deletes your post :(

A note on tags: When passing tags, as params, please pass them as a list (not a comma-separated string):

client.create_text(blogName, tags=['hello', 'world'], ...)

Getting notes for a post

In order to get the notes for a post, you need to have the post id and the blog that it is on.

data = client.notes(blogName, id='123456')

The results include a timestamp you can use to make future calls.

data = client.notes(blogName, id='123456', before_timestamp=data["_links"]["next"]["query_params"]["before_timestamp"])

Tagged Methods

# get posts with a given tag
client.tagged(tag, **params)

Using the interactive console

This client comes with a nice interactive console to run you through the OAuth process, grab your tokens (and store them for future use).

You'll need pyyaml installed to run it, but then it's just:

$ python interactive-console.py

and away you go! Tokens are stored in ~/.tumblr and are also shared by other Tumblr API clients like the Ruby client.

Running tests

The tests (and coverage reports) are run with nose, like this:

python setup.py test

Django admin full Customization step by step

Welcome to my blog , hey everyone in this article you learn how to customize the Django app and view in the article you will know how to register  and unregister  models from the admin view how to add filtering how to add a custom input field, and a button that triggers an action on all objects and even how to change the look of your app and page using the Django suit package let’s get started.

How to create a Django project and a Django application

To start off create a new folder for the Django project and move into it
Here I called django-quick-start the main folder that will hold the project. Pay attention, this is not the actual Django project, but just its “home”. Once inside the new folder create a Python virtual environment and activate it (note, these are two distinct commands)
Pay attention again: django_quick_start now is the actual Django project created inside the django-quick-start folder. The name of this home folder doesn’t matter, but Django projects cannot have dashes in the name. That’s the reason for these underscores in django_quick_start.
Pay also attention to the dot in django-admin startproject django_quick_start … With the dot we can avoid additional folder nesting.

How model queries work in Django

How model queries work in Django

Welcome to my blog, hey everyone in this article we are going to be working with queries in Django so for any web app that you build your going to want to write a query so you can retrieve information from your database so in this article I’ll be showing you all the different ways that you can write queries and it should cover about 90% of the cases that you’ll have when you’re writing your code the other 10% depend on your specific use case you may have to get more complicated but for the most part what I cover in this article should be able to help you so let’s start with the model that I have I’ve already created it.

**Read More : **How to make Chatbot in Python.

Read More : Django Admin Full Customization step by step

let’s just get into this diagram that I made so in here:

django queries aboutDescribe each parameter in Django querset

we’re making a simple query for the myModel table so we want to pull out all the information in the database so we have this variable which is gonna hold a return value and we have our myModel models so this is simply the myModel model name so whatever you named your model just make sure you specify that and we’re gonna access the objects attribute once we get that object’s attribute we can simply use the all method and this will return all the information in the database so we’re gonna start with all and then we will go into getting single items filtering that data and go to our command prompt.

Here and we’ll actually start making our queries from here to do this let’s just go ahead and run** Python manage.py shell** and I am in my project file so make sure you’re in there when you start and what this does is it gives us an interactive shell to actually start working with our data so this is a lot like the Python shell but because we did manage.py it allows us to do things a Django way and actually query our database now open up the command prompt and let’s go ahead and start making our first queries.

7 Mistakes You Should Avoid While Building a Django Application

Django…We all know the popularity of this Python framework. Django has become the first choice of developers to build their web applications. It is a free and open-source Python framework. Django can easily solve a lot of common development challenges. It allows you to build flexible and well-structured web applications.

A lot of common features of Django such as a built-in admin panel, ORM (object-relational mapping tool), Routing, templating have made the task easier for developers. They do not require spending so much time on implementing these things from scratch.

One of the most killer features of Django is the built-in Admin panel. With this feature, you can configure a lot of things such as an access control list, row-level permissions, and actions, filters, orders, widgets, forms, extra URL helpers, etc.

Django ORM works with all major databases out of the box. It supports all the major SQL queries which you can use in your application. Templating engine of Django is also very, very flexible and powerful at the same time. Even a lot of features are available in Django, developers still make a lot of mistakes while building an application. In this blog, we will discuss some common mistakes which you should avoid while building a Django application.
