Case-Insensitive Fields in Django Models
If you are trying to figure out how to create a case-insensitive field for your Django models, there are several ways to go about it. If you don’t care about preserving the actual mixed-case version, you can simply convert your strings to lowercase before they get saved to the model. If you are using PostgreSQL … Continue reading Case-Insensitive Fields in Django Models The post Case-Insensitive Fields in Django Models appeared first on concise coder. -
Django acceptance testing automation with robot framework
Testing is a typical phase in the Web application development flow, because a Web application is made of multiple layers of logic starting from HTTP request handling, to request data validation and processing, to template rendering. But testing phase of a Django Application development, it’s really easy. We use Unittest module built in to python standard library to write the test cases to simulate requests, insert the test data and inspect the application’s output. You can perform automated testing in your Django application using different tools. Few of them are, Writing the unit test cases using the python’s test client Writing the unit test cases using the selenium Writing the behavioral test cases using Django-behave framework Writing the generic test cases for acceptance testing using Robot framework In this blog, let's try to learn of what is Robot framework and how to write simple test cases using robot framework. Robot Framework is one of the best testing automation frameworks for acceptance testing. Which can be very useful in the acceptance test-driven development. This framework uses a keyword-driven testing approach, and it has easy-to-use tabular test data syntax, which is a very effective way to achieve user acceptance testing. This framework … -

Combining Inherited Django Forms in the Same FormView
This week, I discovered the power of Django’s generic editing views and was eager to try them out. I had two forms; one inheriting from the other. I could have them each in their own view, but for a better user experience, I wanted it all to happen on one page by allowing the user … Continue reading Combining Inherited Django Forms in the Same FormView The post Combining Inherited Django Forms in the Same FormView appeared first on concise coder. -

U-Nest App Puts College Savings Within Parents’ Reach
These days, saving for college can seem like a daunting prospect. College costs are distinctly on the rise. Between 1987 and 2017, the average tuition for a public four-year institution increased by a whopping 213 percent, and the average tuition for a private four-year institution increased by 129 percent. That’s why it’s unsurprising that many families’ fears about their ability to pay for college are also on the rise.

Filtering and Pagination with Django
If you want to build a list page that allows filtering and pagination, you have to get a few separate things to work together. Django provides some tools for pagination, but the documentation doesn't tell us how to make that work with anything else. Similarly, django_filter makes it relatively easy to add filters to a view, but doesn't tell you how to add pagination (or other things) without breaking the filtering. The heart of the problem is that both features use query parameters, and we need to find a way to let each feature control its own query parameters without breaking the other one. Filters Let's start with a review of filtering, with an example of how you might subclass ListView to add filtering. To make it filter the way you want, you need to create a subclass of FilterSet and set filterset_class to that class. (See that link for how to write a filterset.) class FilteredListView(ListView): filterset_class = None def get_queryset(self): # Get the queryset however you usually would. For example: queryset = super().get_queryset() # Then use the query parameters and the queryset to # instantiate a filterset and save it as an attribute # on the view instance … -

Adding type hints to the Django ORM
It occurred to me that Django's ORM could do with a bit of a revamp to make use of recent developments in the Python language. The main area where I think Django's models are missing out is the lack of type hinting (hardly surprising since Django pre-dates type hints). Adding type hints allows Mypy to detect bugs before you even run your code. It may only save you minutes each time, but multiply that by the number of code + run iterations you do each day, and it can save hours of development time. Multiply that by the lifetime of your project, and it could save weeks or months. A clear win. Typing Django Models I'd love to be able to use type hints with the Django ORM, but it seems that the magic required to create Django models is just too dynamic and would defy any attempts to use typing. Fortunately that may not necessarily be the case. Type hints can be inspected at runtime, and we could use this information when building the model, while still allowing Mypy to analyze our code. Take the following trivial Django model: class Foo(models.Model): count = models.IntegerField(default=0) The same information could be … -

Evennia 0.8 released
After about a year of work and almost 540 commits from close to 20 contributors, Evennia 0.8 is out! Evennia is a Python game server for creating text-based multiplayer games (MUDs, Mushes, etc) using Django and Twisted.Some of the upcoming improvements have been covered by previous dev blogs, such as the completely reworked server infrastructure: as well as the new Online Creation System that allows for editing in-game prototypes using a powerful menu system: Other improvements are in the web client, which supports split-panes out of the box. The user can split the output area in any number of panes, resize as desired and then assign different types of content to each pane. You can also have panes that absorb "all the rest" or "all" of the content. There are still some bits which are a bit shaky and there is still much to do with the web client (for example, not that many outgoing messages yet defaults to being tagged in a way that the webclient recognizes). But it's a step forward!There are many other improvements for developers, such as easier tools for running debuggers and a lot of new utilities and helper functions. The menu-creation tool (EvMenu) has seen … -
