I started my blog “hellocoding.wordpress.com” in 2013. WordPress.com provides the basic functionality of posting the post for free. It does not give the way to embed JavaScript and does not offer much control over your blog.
After a few years of blogging in WordPress.com, I realised that I want more control over my site so that I can improve my SEO, make a page redirection and make my site how I want in every possible way.
Today i was working on a project where i required to add the invisible button. I tried different methods like making button transparent, adding the image in the button. But then i came to know about this solution. I think that this is probably the best solution.
Steps to add invisible button in Unity3D 1. Add the Button. (UI -> Button)
2. Edit the height and width of the button according to your fit.
Converting list of images to PDF in Ubuntu Let’s use ImageMagick tool. Normally it is installed in Ubuntu. If you need to install it then run:
sudo apt-get install imagemagick Then you can convert it by using:
convert image_1.jpg image_2.jpg output.pdf You can specify any numbers of images but the last argument must be a name of your PDF file along with extension (.pdf).
Adding the watermark in the PDF file We use Python script for adding watermark to each page in the PDF file.
While learning Python in the beginning, i skipped the portion of the chapters on Decorators. After i worked on Flask and Django, I was introduced with the Decorators.
Let us consider a simple flask app example:
@app.route("/") def hello(): return "Hello World!" In this code the line with @ symbol is decorators. Decorators is one of the important feature in Python that you must learn to master it. It is not that hard, so let us learn it.
Sometimes you may find deleting the commit history of your github project repository useful. You can easily delete the commit history by following the procedure below.
It is always useful to keep the backup of your repository in your computer before removing all the commit history.
Let us start by cloning a github project. I am cloning ‘myproject’, you clone yours.
git clone https://github.com/acsudeep/myproject.git Since all the commit history are in the “.
Create folder ’templates’ inside ‘shortenersite’ and then inside ’templates’ create folder ‘shortenersite’.
Inside “shortenersite/templates/shortenersite/” create ‘base.html’ and ‘index.html’. So now paste the following to them.
[shortenersite/templates/shortenersite/base.html]
{% raw %} <!DOCTYPE html> <html> <head> <title>{% block title %}Welcome to mysite{% endblock %}</title> {% load staticfiles %} <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/css/bootstrap.min.css"> <link rel="stylesheet" type="text/css" href="{% static 'shortenersite/css/custom.css' %}" /> <script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script> <meta name="viewport" content="width=device-width, initial-scale=1"> </head> <script type="text/javascript"> $(function() { $('#submitButton').click(function() { $.ajax({ type: "POST", url: "/makeshort/", data: { 'url' : $('#url').
Now we will be working with our actual URLs and Views of our site.
Open up your “urlshortener/urls.py” and add the following code to it:
[urlshortener/urls.py]
from django.conf.urls import patterns, include, url from django.contrib import admin urlpatterns = patterns('', url(r'^admin/', include(admin.site.urls)), # if the URL pattern match /admin/ then open up admin panel url(r'', include('shortenersite.urls', namespace='shortenersite')), # if anything rather then /admin/ then it will look for shortenersite/urls ) Next, create a new file ‘urls.
Now, Let us create a Django app. From your project’s root directory run this command
django-admin startapp shortenersite This will create a new folder ‘shortenersite’ inside our root directory which is actually a Django app. You can see the following files and folder inside shortenersite:
migrations - Contains database migration file.
admin.py - We will use this file to configure Django Admin settings for this app.
models.py - Contains the model (generally model.
Creating a Django project
django-admin startproject urlshortener Now you will see new directory “urlshortener”. Now our folder structure looks something like:
tutorial/ - py3env - urlshortener - urlshortener = __init__.py = settings.py = urls.py = wsgi.py = manage.py (Folder is denoted as - and file is denoted by =)
The folder “urlshortener” just inside “tutorial” is our root directory. And we will work inside this root directory from now on wards.
