better Django Developer by doing a pet project My name is Zhenya Kosmak Now I work as a product manager but I have years of quite serious commercial experience using Django And even now I strive to code for at least hours weekly I deeply believe the best way to master any framework Django as well is to build a truly big pet project So a few bits of my recent pet project experience The pet project s name is Palianytsia It s a tool for enriching Ukrainian vocabulary and generally studying Ukrainian Now months after project public launch we have DAU daily active users across all clients web app iOS and Android apps and a sufficient audience K followers on Instagram The back end of this product is entirely on Django It must be noted that a great developer in the modern world couldn t be imagined as a single player Many tough challenges show up particularly in teamwork So it would be a rather more quality experience if you start your pet project with a team containing competent people for such roles as product owner designer and project manager Your pet project should solve a sufficient number of most standard back end tasks The tasks have to be real not synthetical Here are examples of how you can set them up Main featureIn our case it was a search mechanism on top of ElasticSearch We have a database of sentences from different sources and the task of this API endpoint is to return the most relevant sentences for each query We have additional aspects on this The sentences must show different contexts in which the user s input was used Also the search results should come from various sources in order to include principally different ways to use the search phrase This task teaches you how to work with ElasticSearch and customize its ordering Also you practice using DRF to build quality API endpoints here If you want to obtain excellent documentation of such endpoints you might use drf spectacular or else as well Data collectionDjango developer must be a Python professional as well Not all the everyday tasks are covered with some Django libraries but they still have to be solved HTTP scraping is one of the most standard ones We needed to collect articles from websites to provide users with comprehensive examples of each word or phrase usage So we ve built some abstract parser classes for most routine needs BaseParser We define general parsing logic here BaseFeedPaginationParser We use it to collect article URLs when the website s feeds are paginated i e the URLs of the feed look like page gt BaseFeedCrawlerParser On some sites there were no paginated URLs they had only infinite scroll or Next page URLs on each page This parser works with such websites Also we use it for Wikipedia BaseArticleParser This guy is used for collecting the content of each article Such class hierarchy was a definitely productive solution After finishing work on these classes developing a parser was mainly like writing a config file For example class DetectorMediaBaseFeedParser BaseFeedParser start date datetime date def feed urls self gt List str return f self base url archive d strftime Y m d for d in date range self start date today class DetectorMediaBaseArticleParser BaseArticleParser paragraphs selector artelem gt p def extract paragraphs self dom HtmlElement gt List str Current markup paragraphs super extract paragraphs dom if paragraphs return paragraphs Old br only markup content cssselect one dom artelem paragraphs split br into paragraphs lxml content if content else return paragraphsYou can only guess what a mess we could get if we developed each parser separately It s also an excellent practice for requests asyncio or anything else you prefer to get the data from websites When you ve made similar scrapers from scratch…This task also teaches you how to orchestrate those parsers We had to gather millions of articles based on our estimates and we wanted to be able to collect all data from all sites in hours So we have to use a tasks queue to ensure the solution is efficient and scalable The most common approach on the Django stack is to use celery but we prefer dramatiq as the most lightweight and still productive one Bringing such a solution to a stable and scalable level is also a very effective way to improve your coding skills Last but not least we need a state here We have to save each gathered URL and article content after scraping so we wouldn t lose the work results if our server crashes And the content is stored in S Wasabi cloud storage Here is your practice with PostgreSQL or any other RDBMS you d like and S as well Data processingOkay we have articles what s next We need a database of Ukrainian sentences split properly with filtered artifacts such as BB code parts or broken HTML which occurs on most websites normalized we don t need repeated spaces or else As input we have a PostgreSQL table with articles each article is stored on S storage and split into paragraphs So we ve got such tasks Split a paragraph into a list of sentences The job looks easier than it is No way it s something like paragraph split it s way harder For some direction you can look at this StackOverflow question Skip all paragraphs with mostly non Ukrainian content Filter out trash content Let s add some rd party toolsSometimes when you want to say something in one language you can only recall the word or phrase in another So let s add Google Translate so that our users would be able to enter queries using any language and we will search for translation in our database It s a nice opportunity to practice using dependencies google cloud translate storing credentials and even developing a cache mechanic The last one would be helpful to decrease the number of requests sent to the API so that we will spend less By the way if you send less than K characters monthly you wouldn t even be charged with Google Cloud cause it s free under that limit And one more tricky task The user searches a query Should you or shouldn t you translate it There are several ways to solve this issue We decided to go this way we stem and normalize all the words from the query then we find all of them in our dictionary of Ukrainian words We definitely shouldn t go for a translation if we found all of them Else way we better get it User related mechanicsWe need authentication authorization registration password recovery ーall that boring stuff It s a good chance to practice django allauth dj rest auth djangorestframework simplejwt Remember such things Users shouldn t be logged out for no reason so cookies shouldn t expire in one hour Their credentials must be safe so that should be HTTP only cookies and data kept secure on the server side All errors must be processed intuitively and logically so the front end part will be easy to develop Developing rd party authentications is also a good idea for new technical experience Adding Google or Facebook as sign up methods might be a more intriguing task than you d imagine Should we do some automated tests This many tests we ve made Of course we should But please don t do it like your home assignment at university Choose the most vulnerable parts of projects for future developer mistakes and cover them up In our case we made such ElasticSearch test for disk usage RAM and response speed Actually we did this before all else in this project as a part of the proof of concept stage We filled the ElasticSearch DB with dummy data and used ApacheBench and some write only Python scripts to test the performance on the production level server Performance tests on the primary endpoint to ensure we ll endure the load These tests were added to the stable code base so that we could rerun the test when needed Unit tests for parsers text processing mechanics and string utilities So that we can be sure that our technical solutions would be changed only in a conscious way Bottom lineLet s summarize On such a pet project you can effectively learn General business logic development When you have a real world task the coding experience becomes more fluent Work with mainly used databases Any project relies on them so if your task is challenging enough you may learn those well Task queues They become vital just as you encounter any IO bound CPU bound or high loaded objective Choose high restrictions and you learn it well for sure rd parties They are an integral part of any product The more you learn the better you re ready for the next ones Network libraries Not to say vital but an omnipresent piece of knowledge you d definitely need Any pet project will acquire your attention on this point Tests Not homework but real salvation of doing error twice It s almost the same as spending a year on a commercial project But you can do it yourself and if you are patient and stubborn enough you can master it So think about it And the last thing If you are thinking about something bigger than a pet project you can talk with me directly or check out our cases on Daiquiri Team	2022-08-16 16:23:44
海外TECH	DEV Community	What display: block does?	https://dev.to/melnik909/what-display-block-does-56mh	What display block does In my experience a lot of problems with CSS happen because developers have problems understanding the display property So I created a live cheat sheet In this article I ll talk about display block But before embarking on reading I leave the link on my Substack newsletter about CSS You know what to make Let s go Default behavior The width property of elements with display block fills up all available space by the text direction The height property of elements with display block is calculated automatically depending on the content If the content of elements with display block doesn t fit on one line then browsers will move it to a new line The elements with dispay block always start on a new line Box model features The width and height properties can be set to elements with dispay block The padding and border properties can be applied too But surprises wait for us when using margins because they might end up outside the parent And if we set the border or padding property for the parent margins stop to end up outside it That will work in the case when using vertical paddings or borders but doesn t with horizontal When adding padding or borders with only one side margins will stop ending up outside the parent with this side but will still with the opposite Margins stop to end up outside the parent after adding the overflow property with a value that s different from visible In the case of the parent with a few items margins before the first and after the last element end up outside the parent In this case adding the border padding and overflow property for the parent ceases this margin behavior The margins of adjacent elements with display block collapse too The browsers choose the biggest between the two The padding border and overflow properties can t change it P S Get more free tips about CSS directly to your inboxThank you so much my sponsors Ben Rinehart Jesse Willard Tanya Ten Konstantinos Kapenekakis	2022-08-16 16:20:52
