[@DennisIvy]

Thank you!

[@taharehman6439]

sorry

[@GabrielRibeiro-xr3bx]

Hey man, The best about your tutorials is that you show the errors. Sometimes that`s more important for the learning process than the rest. Specially to me, as a complete begginer, sometimes a mispelled word makes me break my head, as I have not yet gained the ability to understand the complete inner works of the code. Showing the little errors you make, makes me more skilled to deal with my own, I guess. Thanks for the amazing work.

[@justmeldin6062]

You my man, you are THE BEST teacher I have ever seen in my life. Best teacher I have ever seen and not just in industry of coding and computer science, I mean in general. I hope that you continue in this endeavor of teaching and breaking down hard topics. You nailed everything here...tact, speed, level of voice, how much you stay on certain issue, how you explain and connect the dots... every single part of your lets say style of explanation is such that immediately sticks in my head. Don't get complacent and work hard as you already do. Think that you are not good enough :) Peace bro

[@yoip1234]

Thank you Dennis for running this series. It's one of the best tutorials that I have seen. You have done a great job!

I can't believe that way of handling forms. Django is so powerful! Thanks for this playlist!

[@parthaprateempatra4278]

This is a very nice video which doesn't use generic classes for CRUD instead makes everything from scratch to allow more flexibility

[@damilareadeniyi1195]

I really like your series I watched a bunch of other tutorial and did not understand much. They gloss over a lot of things and don't explain it well for beginners. I think the fact that you are self taught makes it easier to understand most people situation.

[@nihalsaket]

Great content overall. However, I found following a lot of things in this particular video (pt 10) a bit tricky. What I really like about your Django tutorial is that you explain every syntax/keyword you write. Found you rushing from 9:00 to 12:00 in (pt 10). Would be great if you can post an explainer video for pt 10 in case you have the bandwidth to do so.

[@ionutmuntean2177]

yeah, at 08:25 I didn't understand either why the if-check if we know that we always get a POST request?

[@82-sagarshah17]

Sir I attend other tutorials in KZbin and I confused so much and my competence go down and there codes are more complicated... After watching you video I got everything in easy way ...

[@DennisIvy]

Yes I agree. Keeping things simple with as much vanilla Django as possible but we will be using lots of JS in the next projects. I plan on making a rest API course and then using that api to render data for a twitter clone app :)

[@TjaartSwanepoel]

Dude, your content is brilliant. Thanks. Keep 'em coming. IDEA for a video, please consider doing a video on form elements like custom radio buttons and check boxes as well as date and time pickers. You could also please do a video on drop down boxes that refresh one another, like when you select a category, the second dropdown is refreshed with its sub categpries etc and then the products of that sub category(actually currently struggling with that one).

[@DennisIvy]

Thank you Tjaart! Pretty much everything you mentioned is on my todo list :) These are all things I struggled with when I first started. I wanted to make them into their own separate videos so I can cover each concept thoroughly.

For the load static you had to put it in the "navbar" template because it did not inherit from the" base.htlm" although in the order_form you don't need to put it because the load static is already in the base.html

[@Serwik42]

You saved my entire life bro I love you

[@ionutmuntean2177]

At 08:25 I didn't understand: why the if-check if we know that we always get a POST request? EDIT: I think I got it (actually this is a bit of a revelation for me, hopefully it helps other people that are just starting with web development, too) The way I answered myself is as follows: basically, with any URL that you access in this whole wide world YOU FIRST MAKE A GET request. And so - in our case - the first time you actually access "/create_order" you actually do not want to make any modifications to the DB, but what you'd rather want is for the form to be displayed to you, so that you AFTERWARDS CAN actually fill the form and then click submit which then in turn sends a POST method, which makes our app access the same createOrder again but this time with a POST request, thus the flow of the code will enter the if-check there.

[@TheNoviceCreator]

in the redirect you can specify the name of the url, so that (as you explained previously) it will not suffer of url changes

[@danilotavares77]

Hi Dennis! Thank you for you videos. They are really helpful. One question, if I may: in a case that you need to create a register using a form that has require foreign key field in the model, would you use the model form? How to handle the situation when you need to create not just the record for the main form bu also a new register in the foreign table?

keep up the good work, man. i'm in love with ur tutorials. but why u use model form instead of class based view? bcos u said earlier u'd explain it later but i didnt catch u mention in this video.

[@elnazdehkharghani6121]

Dear Dennis, I have finished this video till at the end of it but I have got a problem with order_form.html. I can not see my form fields there. I can only see forms attributes name there in disable formats without any drop-down menu :( my output is only theses in grey and disabled: ==> (Customer: Product: Status:)

Thanks 4 content. But i have a question what is use of action attribute of form that you only used in delete order? U didnt use action in rest other cases like create or update

[@dannyargueta5821]

Great video ! I want to know how to make an update without passing the id though the url. I think this could be unsecured cuz everyone can type some ramdom id and get access to ramdom row from the database, same as Delete process. so if you can help me with this I'll really appreciate it. thank you so much

[@masterhipster8358]

Hi Dennis, love your videos.. can you plz tell how we update date also while user update data.. In this videos the date was not updated.. Its will help to me if you guide me

[@mychromebook9935]

how are you passing request.POST into the function OrderForm(request.POST, instance=order) ? 16:14 Seems confusing when Order(model.Model) and OrderForm(ModelForm)

[@aleksandarradovic2960]

Thank you so much for these videos! I just have one question: Should paths in urls.py be with dashes or underscores? Those paths are displayed in the web address later on, and djangoproject website has dashes in their website instead of underscores. I cannot find a definitive clear answer on the web, but my guess is that dashes are preferred. Example: path('create-order'...) instead of path('create_order'...).

[@adityamahajan1238]

This was really a nice work, I really liked the way you take things from very basic to advanced level, also thanks for not having a sophisticated front end, I was using basic HTML so was able to follow, lol! One thing that helped me was how you used POST method to make a PATCH request. Another thing you can add is to PATCH only few fields in our model, I did by creating a second form and inheriting required fields from the model, is there any other way to do that without creating another form?

[@cezar-alexandrujavad5731]

the Form is not showing...like it shows to you at min 8:05

[@juanespinosareinoso7094]

I really like your tutorial. Kudos Dennis for the great work. Keep your amazing work. I have a question: In the tutorial you are creating an "createOrder view" from the admin/general dashboard. How about if you are inside a user-info view (only the user info appears when they login), how should be the view if the user wants to create an order? I am a little bit confused on how to call the orders for that specific user to create a new order. Thank you so much in advance.

Thanks the course is great and the most valuable. But i have a question in the delete form at 21:23 ,why do we need the action? Every thing is controlled inside views.py>deleteOrder function, am i wrong?

[@DennisIvy]

Action is telling the form which page we are sending the data to. It will then send the data to the view associated with that URL. If we left it blank it still would have worked because by default it will send the the URL of the page you are on but its best practice to specify exactly where you want the data to go.

I found a solution. When referencing a model in html the function {% for x in y %}. This means when referencing in the href, you have to use x not y. For example href="{% url 'path' pk=x.id %}. Hope this helps. Any questions just reply. :)
