[@subikeshps2289]

To convert the inputs to integer, the int() function works good, even with double quotes. Perhaps in this video, the refresh didn't work correctly. Great explanation sir. I really like your tutorials.

[@thirumalairajan3540]

thanks bro you have solved my doubt

[@skviknesh]

Flow explained above SIMPLIFIED: Here we need to enter 2 numbers, add them & print result in new page. 1. In the home.html create a form to add 2 numbers home page. a. Need 2 text fields to get values & button to submit it. 2. Need a page to display the results (result.html) - create it. 3. Created a new page, need to register in "urls.py". 4. Now, page is created & registered in URL's => now we need logic for it. a. Create a function to add in "views.py" which gets the response from "home.html b. And return to "result.html 5. Finally, in "result.html" receive response in a variable. 6. DONE. Create a page -> register it in urls -> write logic in views -> receive in results.

[@varunkrishnaKyathanpally]

Awesome tutorial. I understood that once we practice Django more, we can play with it.

[@manpreetkaur6908]

Excellent stuff... I always watch your tutorials whenever get stuck...

[@sauravrai5840]

Great explanation and love the energy and passion which you teach :)

[@olkhovskyrus]

Another solution to add numbers but not strings is to wrap variables in int() as we sum them. In my case it was c = int(a) + int(b)

[@Canadoloteluguammai]

Hi Navin, can you explain me what does render module does ? In 6:42 return render(request,"result.html",{'result':res}) what does the third argument does ? how to create that and can someone explain me in brief?

Hey, Navin! Is it absolutely necessary to have knowledge of HTML/CSS and JavaScript before starting Django or Can we learn it as we work on Django along the way? Your tutorials are awesome by the way. :)

[@friendlycreeper1045]

It is necessary to have knowledge of HTML/CSS but not javascript cuz we are replacing it with python (Django). You can learn them along the way too

[@djameleddinechahrat4926]

sir, can i use opencv with django?

[@306Drago]

In home.html you have to change the input type from "text" to int, then only it will accept addition.

[@rohansoudey6005]

In path() what is use of name="" ?

[@hasib4joy]

If in the future you have to call the path. you can simply call them by the name. suppose calling the result page by /result, you can call call them by the name result. You will get the impact when you will have numbers of urls under one app.

[@s2rthoughts425]

i think you can use the name instead of page
