JavaScript. The definitive guide to django 2nd edition. Python and Web: Building Dynamic Web Forms in Web2Py from Ground – Part II. In the first tutorial of this series, we dived into the basics of creating web forms in Web2Py. We saw how easy it is to create dynamic web forms and how smoothly their inputs sync with the database. Assuming that you have followed it, let’s play even harder. 1. Updating and Deleting Form Records: Many of you should be wondering about how the form data provided through this form can be edited, updated or even deleted? Well, this is simple. First, let’s recall the form_a function that we have created in the default.py controller: def form_a(): form = SQLFORM(db.registration) if form.process().accepted: response.flash = ‘You have successfully submitted the form’ elif form.errors: response.flash = 'Please check your form for errors' else: response.flash = 'This form cannot be left empty!

' This is a very meanly written controller function (I admit it), which only supports the insertion of input data. Well, we have added a ‘bit’ something in the above function, so allow me to explain it all. Bootstrap. Critica/INSTALL at master · brunobord/critica. Stripped-down Django Tutorial | Tony Abou-Assaleh.

The django official tutorial consists of 4 parts, unnecessarily long, mixes commands with text, and omit some important details. Here is an attempt at providing a more complete and more condensed version of the tutorial. Et Voilà! These steps cover most of the 4-part tutorial, excluding templating the admin area and using the generic views. For completeness, I include a sample apache config file that uses virtual hosts so you can go through this tutorial with apache. <VirtualHost *> ServerAdmin webmaster@localhost ServerName django-tutorial.osrd.org DocumentRoot /path/to/django-projects/mysite <Directory /path/to/django-projects/mysite > Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> ErrorLog /var/log/apache2/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg.

Oscar ships with two sample projects: a ‘sandbox’ site, which is a vanilla install of Oscar using the default templates and styles, and a fully featured ‘demo’ site which demonstrates how Oscar can be re-skinned and customised to model a domain. The sandbox site¶ The sandbox site is a minimal implementation of Oscar where everything is left in its default state. It is useful for exploring Oscar’s functionality and developing new features. It only has one notable customisation on top of Oscar’s core: A profile class is specified which defines a few simple fields.

Note that some things are deliberately not implemented within core Oscar as they are domain-specific. All tax is set to zero.No shipping methods are specified. The sandbox is, in effect, the blank canvas upon which you can build your site. The demo site¶ The demo site is the reference Oscar project as it illustrates how Oscar can be redesigned and customised to build an realistic e-commerce store.

You can use it to create general graphics and it can be used to create custom widgets. It's worth knowing about. The canvas widget is "just another widget" and in this sense you already know quite a lot about how to use it, but there a few specifics that make it more than "just a widget".

The canvas widget can be added to a suitable container often the root window in the usual way. For example the simplest canvas setup program you can imagine is: from tkinter import *root=Tk()w = Canvas(root, width=500, height=500)w.pack()root.mainloop() This creates a canvas widget 500x500 pixels and sizes the root window to fit. You can also add a border to the canvas, but there is one small problem - it sits inside the canvas coordinate system which means you can't draw in the space it occupies. For now to create a canvas without a border or anything that obscures the edges of the coordinate system use: A Retained Vector Drawing system w.delete(ALL) Full Web Framework Python Django Tutorial XI Blog - Advanced Template - Linux/Ubuntu/Windows.

Python & Web: Building Dynamic Web Forms in Web2Py from Ground – Part III. Welcome to the third and final tutorial in the series of creating dynamic web forms using Web2Py. In the second tutorial of this series, we talked about editing/updating/deleting the submitted form records as well as management of those records using an ingenious function named SQLFORM.grid(), which allowed us to import and manage our form records in a pre-built environment having security features enabled.

In this third, and final tutorial of the series, I would like to shed some light on how multiple web forms can exist on a single page, how a single form can submit data to multiple tables, and finally, a hint about modifying CSS of your web form (which is a common practice in classical PHP based web forms). Okay, let’s go. 1. Multiple Forms on a Single Page: As the header suggests, we are going to integrate more than one web forms on a single page, arranged serially against each other. Now we have two database tables named ‘registration’ and ‘personal’ having following fields: personal: Stephenmcd / mezzanine / source / Mezzanine is a powerful, consistent, and flexible content management platform.

Built using the Django framework, Mezzanine provides a simple yet highly extensible architecture that encourages diving in and hacking on the code. Mezzanine is BSD licensed and supported by a diverse and active community. In some ways, Mezzanine resembles tools such as Wordpress that provide an intuitive interface for managing pages, blog posts, form data, store products, and other types of content. But Mezzanine is also different. Unlike many other platforms that make extensive use of modules or reusable applications, Mezzanine provides most of its functionality by default. This approach yields a more integrated and efficient platform. Visit the Mezzanine project page to see some of the great sites people have built using Mezzanine. Features In addition to the usual features provided by Django such as MVC architecture, ORM, templating, caching and an automatic admin interface, Mezzanine provides the following:

Your First Application. To add the first view to your application, define an HTML template that will be used to display this view. Add a div element with the data-options attribute set to dxView.Give a name to the view by assigning a configuration object with the name option specified. The specified name will be used to identify the view.

The framework follows the Model View ViewModel (MVVM) pattern to provide a clean separation of the user interface from the business logic. An application consists of a set of Views defined by an HTML5 markup and the accompanying resources (images and CSS3 styles). Views can be bound to the corresponding ViewModels via the Knockout JavaScript library. The ViewModel is basically your custom JavaScript code, which is responsible for providing data from the Model to the View taking into account different user interactions. Actually, the HTML template presented above is a View of the "home" view in terms of the MVVM pattern, because no css classes are used in this template.

Web2Py - pyfpdf - web framework integration for PDF report and templates support - Simple PDF generation for Python (FPDF PHP port) AKA fpdf.py. At this point you could go to web2py AppAdmin and start to define your document templates, or use import/export functions to reuse your already defined formats! Note: if you used designer.py to create the templates, and you want to import the templates with the Web2Py database admin you will have to modify the file. So; designer.py outputs a file like this: {{{line0;T;20.0;13.0;190.0;13.0;times;10.0;0;0;0;0;65535;C;;0line1;T;20.0;67.0;190.0;67.0;times;10.0;0;0;0;0;65535;C;;0name0;T;21;14;104;25;times;16.0;0;0;0;0;0;C;;2title0;T;64;26;104;30;times;10.0;0;0;0;0;0;C;;2}}} You will have to make it look lke this: A simple python script should do the trick.

After defining and filling your database, you can use PyFPDF [Templates] directly reading rows elements from the web2py database: For example, for an invoice, in a controller you could write:{{{def invoice(): from gluon.contrib.pyfpdf import Template import os.path # generate sample invoice (according Argentina's regulations) # last page?

In particular, some mathematical expressions are not translated correctly. The goal of this book is to teach you to think like a computer scientist. This way of thinking combines some of the best features of mathematics, engineering, and natural science. Like mathematicians, computer scientists use formal languages to denote ideas (specifically computations).

Like engineers, they design things, assembling components into systems and evaluating tradeoffs among alternatives. Like scientists, they observe the behavior of complex systems, form hypotheses, and test predictions. The single most important skill for a computer scientist is problem solving. On one level, you will be learning to program, a useful skill by itself. 1.1 The Python programming language The programming language you will be learning is Python.

Follow this step by step process to create your own stylish contact form completely out of HTML5 and CSS3. We’ll be using a couple of the handy new features in HTML5 to add cool functionality to our form, while making use of cool CSS3 properties to recreate our Photoshop concept purely in code. The design we’ll be building features all the things that make a rich interface; gradients, highlights and shadows! We’ll create a visual concept in Photoshop first of all, but when it comes to building the form we’ll recreate every effect with HTML5 and CSS3. View the HTML5/CSS3 form demo Open up Photoshop and create a new document. Add a dark to light blue gradient to the background, then draw a rectangle in the centre to contain the form. Use Photoshop layer styles to add a subtle drop shadow at around 30% opacity and a thin 1px stroke using a very light grey.

Add a title to the design using the darker blue colour swatch. The visual concept is now complete. <! Chapter 1: The way of the program. Go programming. The Go Programming Language. Making a Beautiful HTML5 Portfolio. Martin Angelov In today’s tutorial we will be making a beautiful HTML5 portfolio powered by jQuery and the Quicksand plugin. You can use it to showcase your latest work and it is fully customizable, so potentially you could expand it to do much more.

The HTML The first step is to write down the markup of a new HTML5 document. Index.html <! In the body, there are a number of the new HTML5 elements. The #stage unordered list holds our portfolio items. You can put whatever you want in these li items and customize the portfolio further. Beautiful HTML5 Portfolio with jQuery The jQuery What the Quicksand plugin does, is compare two unordered lists of items, find the matching LIs inside them, and animate them to their new positions. First we need to listen for the ready event (the earliest point in the loading of the page where we can access the DOM), and loop through all the li items detecting the associated tags. script.js – Part 1 Each tag is added to the itemsByTags object as an array.
