提交后注册表刷新，而不是在 django 中发送 post 请求

Question

I'm trying to register a user but the page refreshes instead of submitting the data.

At the initial stage of my project, it was working properly but when I added some more models and form it's not working and tried to register it stopped working.

and it also doesn't throw any errors

I would also like to request some other suggestions on my code. Thank you.

Answer 1

Well, it's a silly mistake. I think by mistake you put request.POST inplace of request.method .

In your register view change

if request.POST == "POST": 

to

if request.method == "POST":
