[@johntwalkerv1647]

Just getting into these after digging through some other tutorials. Got to say, these are the best I've seen by far! I found your "I sold my Django app" video, and searched your uploads to see this. Great job! Thank you for your efforts here!

[@cesaralvarez9436]

The same as I, Dennis is a really good teacher.

[@jakobfredriksson2272]

My young intelligent man, THANK YOU! It's astonishing how hard it has been finding a simple, yet brilliant, tutorial like this one. I'm actually quite confident in python programming in general but since I began to learn Django (or web development in general) this summer I've been completely lost due to the logic -the relationship - between views, templates and models. Yes, I've read the docs quite a lot but find them inconsistent in some regards but after this tutorial most, if not all, of my frustration disappeared. Wish you all the best!

[@rachiddz8656]

I was about to give up. I came back again after watching Ivy's videos. Thanks bro.

Dennis, thanks a lot for your effort and dedication! Great tutorial with clear explanations of core concepts. I have got a suggestion)) It would be great if there would be a video tutorial which shows how to render data from 2 database tables, which have the one-to-many relationship, into one table on the webpage (it would be great if custom-template tags could also be covered)

This is awesome django tutorial! Im appreciated for uploading your video.

[@nahidosen]

You just saved my life. Thanks

[@amazonfbaphotographer7333]

What I don't understand is how you decide to place "for example" the code for total orders, pending order, etc in the views.py section/file. I guess it's obvious so everything is organized, but still, have trouble understanding the decision-making on naming the files. Thank Dennis, learned a lot in these past days of going through your channel and courses!

Hey Dennis, i'm stuck and really i don't know why. When i set on views orders and customers with ***.objects.all(), i get this error "Exception Value: 'function' object has no attribute 'objects'". Maybe is something stupid, but i cannot understand where's my mistake.

Just check which model gave that error then Just change the model name,it conflicts on the naming convention,so just change the model name.💯 Fix.I fixed it in that way.

sir ,all the queries u have written in views.py like total_customers =customers.count()...is these queries are same if i changed the database..let say mongoDB.?

[@mokk7134]

mongo isnt sql database so possibly there are other queries

[@rababmahdi2920]

delivered = orders.filter(status="Delivered").count() would you please explain this line of code once again? specially this:- status="Delivered".

[@DennisIvy]

So because we are using the "filter()" method instead of "all()" we can filter by the "Order" models "status" attribute. So we are saying "Give us all orders that have the value of "Delivered" in the status field." Then because "orders.filter(status="Delivered")" returns a queryset/list with all the orders containing the status of "Delivered" we can use the count method to total up how many orders are in that queryset/list and return the total number. Its the equivalent of running the python len() method on a list. Does that make sense?

[@fahanfarooq3844]

hey i tried using __str__(return self.customer ,self.product) in the Order class that worked just fine till now.Now, it shows type error (returned non string type "tuple") but without that chunk the code works fine! why so?

[@tonyd9120]

You can only return a string. In the order model both customer and product are foreign key references to their respective models. I haven't tried it but you could probably make it valid by using "return self.customer.name, self.product.name". This way it is a string as both the name fields are strings.

[@fahanfarooq3844]

@@tonyd9120 still the same error !

[@787ankur]

You can convert them to string using string formatting def __str__(self): return f'{self.status}_{self.customer.name}_{self.product.name}'

So if it is possible, will be very thankful if you can help me. I try to doo link in my table to database info, as in your video: {% for order in orders %} {{order.contract.client_contr.company_name}} And it is work. when try to get info from child table into Parent table, without any problem. But when I need to get the same result from parent table to Child, I can't do that. example: {{order.statusesorder_set.num_waybill}} I didn't get any info from it. I even try to use related_name and still didn't get any info This table StatusesOrder has ForeignKey to Orders class StatusesOrder(models.Model): order_stat = models.ForeignKey(Orders, null=True, on_delete=models.PROTECT, related_name='statorder') So I will be very thankful if you can give me advice!
