Thank you for all the videos you dropped on Django. You have spotlighted some features that are buried within the Django documenting that some people might have not seen due to Django’s vast documentation. This showcases the power of Django’s features.
Thanks Jon, that is a very measured analysis of the content in this tutorial. It is very difficult to find and balance the various expectations of the audience.
@@veryacademy You can not always please everyone with the content that is released. Someone always wants something else that you may have not released or based on a project they are working at the time. People need to take the examples that are released and experiment with them or use them as stepping off point to look deeper into the topic that was presented. Thanks again
Hey Fernand. Glad you messaged. Apologies for lack of e-commerce. I am working on v2, don’t have an eta but will focus on some Django relative subjects that can be incorporated
This is great, I'm trying to remove the dependency to elasticsearch in our project. Do you have any advise on how to put everything together (Triagram, SearchRank, full text search) to get search results as close as what elasticsearch would return?
Thaaaaank you so much for this video. I learned a lot. but I have a problem with the index part. It doesn't improve the query time at all, I don't know what the problem is!
Thanks to your lecture, I reviewed bread and butter of django, docker setup, and learned how to improve query performance by using General Inverted Index. May I ask what is prefix-match labels in postgres? It would means that Postgres finds data whether prefix are matching or not, but I'm not sure of it. Suggestion: It would be good to add a statement about q variable, since we might get 'UnboundLocalError' Thank you Xander. I really appreciate it.
Hello everyone, I would like to congratulate you on the quality of your videos. I would like to know if you plan to make a video on django elasticsearch dsl drf? I would like to learn a little more but the documentation is too big and I get lost
Thank you! May I know why do you need to use Docker instead of the regular PGAdmin4? Will this work when deploying the app in AWS Elastic Beanstalk? How do you search using TrigamSimilarity with multiple inputs from the form fields and model fields? Thanks!
***IMPORTANT*** If someone has problems with Django authentication in Postgres or you cant see migrates in pgAdmin, check if you have installed Postgres in your local machine and delete it because conflict occurs and many errors happen
At the end of your video, Book.objects.filter(title__trigram_similar=q).annotate(similar=TrigramSimilarity('title', q)).order_by('-similar') returns an empty list on my machine soI can't tell if GIN_index is working. Could you give us a similar code line that would return some book objects in few milliseconds?
please answer me question on e-commerce project wich is : when i add item to the basket without login i have session id ,and when i login i have different session id but it still remember the item i put in the basket ? is it using the cycle_key() function to obtain new session id while retaining the data inside the old session !?
Hi Abdelrhman, thank you for your question. When you log in you are storing the basket data and the login data in your session. docs.djangoproject.com/en/3.2/topics/http/sessions/
@@veryacademy course_objects.annotate(rank=SearchRank(vector, query)).filter(rank__gte=0.1).order_by('-rank')... Yes found this way to filter now it's fine.. can I use both SearchRank and Trigramsimilarity at the same time?
Yes, you can certainly build APIs (Application Programming Interfaces) that involve Full-Text Search (FTS). Full-Text Search is a technique used to search and retrieve text data from a database, and it's often applied in various applications, including APIs.
Thank you for the reply, I have worked as a backend developer (DRF) before, I'm going to purchase your Django ORM mastery on udemy today, what are your suggestions or road map for someone to master Django?
Hello sir , You are a genius 👏. Can u help me? User has signup in django but if user will not login within a week then sign up is automatically expired? Can u give me some advice for above problems? Please reply
Sure, on signup capture the time/date in a new field called say account created. Make a cron job to check last logged in date and trigger an action. Maybe you flag their account using a Boolean field as expired and another cron job deletes the account after another set time.

Yes it’s ranked the whole queryset, you need to filter

Sorry mate, not sure I understand you?
