In this step, you’ll set up the SQLite database you’ll use to store your data (the blog posts for your application). See How To Install and Use SQLite on Ubuntu 20.04.

PrerequisitesĪ local Python 3 programming environment, follow the tutorial for your distribution in How To Install and Set Up a Local Programming Environment for Python 3 series. Users can create, edit, and delete individual posts. The web application will be a basic blog that displays posts on the index page. In this tutorial, you’ll build a small web application that demonstrates how to use SQLite with Flask to perform basic data manipulation covering CRUD: Create, Read, Update, and Delete. Using SQLite with Python also requires minimal setup compared to other database engines. SQLite works well with Python because the Python standard library provides the sqlite3 module, which you can use to interact with any SQLite database without having to install anything. SQLite is a simple and fast open source SQL engine that can be used with Python to store and manipulate application data. For example, you might not want users to add posts with no titles.įlask is a lightweight Python web framework that provides useful tools and features for creating web applications in the Python Language. The actions you perform to manipulate data will depend on specific features in your application. In a web application, these requirements might be a user adding a new post, deleting a post, or deleting their account, which might or might not delete their posts. You can add data to a database, retrieve it, modify it, or delete it, depending on different requirements and conditions. For example, in a social media application, you have a database where user data (personal information, posts, comments, followers) is stored in a way that can be efficiently manipulated. You use a database to store and maintain persistent data that can be retrieved and manipulated efficiently. In web applications, you usually need a database, which is an organized collection of data. Hope this helps and that the company fixes the minor disappearances.The author selected the Free and Open Source Fund to receive a donation as part of the Write for DOnations program. This weird glitch has caused a lot of people to think there stuff is gone and throw the flash drive away or return it. Until the company solves this problem, I’m giving it 4 stars. Just plug the thing into a laptop when things disappear after a few days and everything will come back. You can save all of your things accordingly. It’s inconvenient but that is the only complain I have about this thing. Then take the flash drive and plug it into your phone again. Weird right? Plug it in, you will find everything you saved on the computer. Your files will disappear after a little bit but all you have to do is plug the flash drive into a computer or laptop. So for all of you that say “it stopped working” there’s an easy fix. HOWEVER, I found out how to get them back. So, I got this app and the flash drive, and like everyone said, it stopped working after a week. So, I-FlashDeviceHD developers, I’m open to apologies, refunds and replacements! Needless to say, I’m more than a little peeved about this little adventure, and out somewheres in the neighbourhood of $40. And because it’s sent from China, with a return address in Chinese only, my local post office couldn’t take it (a company from a country that utilises a non-latin/roman alphabet probably has a good return policy if it has the address in the languages of both countries involved - the post office may require it. And that’s where I read that it my iPhone 7+ is not compatible - it only goes up to 6! I checked before ordering for compatibility issues and found no exclusions. So it’s now a few months later and I’m u, “Maybe they fixed the app, give it another try!” And fix it they did. Should have taken that “Evelyn Woods” speed reading class years ago, because I just couldn’t glean a thing in those 5 seconds. App would my be visible for less than five seconds, then disappear. I thought maybe I could get some answers after downloading the app. The device, no click - in fact, it mmost of the time. Power cord fits snugly into the phone with a palpable click. It looks just like the tab on the power cord from all angles. When I got the “device” it didn’t really seem to fit into to phone. If you’re here, you’ve already “paid” (and regretting it)
