class ProfileForm(forms.ModelForm):

)
I really cannot understand why this error happens because I did not write user_id in NewUser models.I think Integrity Error means columns cannot be found in Model.OneToOneField can be connected withUser and NewUser's model .I think this error means I should prepare user_id in New User model but if my thinking is right, I cannot understand why.How should I fix this?What should I write it?
This happens because in the NewUser model, the user field is a required field. In the ProfileForm the user field is not included. So when the ProfileForm tries to save the NewUser without user attached to it, it results in the above mentioned error.
What we have to do is to attach the user to the instance before actual save happens:
profile = profile_form.save(commit=False)
profile.user = registered_user # you can get the user from the registerform above
profile.save()

By the way the statement print(f"THe first name is {first_name}") isn't working, meaning the form isn't being accessed however when I hit the submit button, the terminal outputs a POST request
Here is the HTML page in which the data should be shown
It might be that you need to explicitly set the id value for each of the inputs in your modal. You have name specified, but I think id is a more stable option when collecting form data.
If you're running this locally in dev mode (via terminal/cmd line) I would absolutely suggest throwing a breakpoint() in before print(f"The first name is {first_name}") and look at what values request.form actually returns.
i tried creating timer in python but its not being as i wanted so i guess javascript is only going
to help and im not very good in javascript do please help me to create a timer and page should close when timer runs out of time

I was trying to make a basic banking system using Django, in which a user can transfer money to other user. But when I tried to transfer money nothing happens, probably because transfer function in views.py is not being executed.
Here are transaction.html file and transfer function from views.py :
transaction.html
{% extends 'bank/base.html' %}
{% block content %}
<div class="container">
<h2>Transfer Money</h2>
<form action="{% url 'transaction' %}" method="post">
{% csrf_token %}
<label for="s_acc">Select sender details</label>
<select name="s_acc" required>
<option value="select">Select</option>
{% for cust in customer %}
<option value="{{cust.account_number}}">{{cust.name}}: {{cust.account_number}} : {{cust.balance}}</option>
{% endfor %}
</select>
<br>
<label for="amt">Enter amount</label>
<input type="number" name="amt" required>
<br>
<label for="r_acc">Select receiver details</label>
<select name="r_acc" required>
<option value="select">Select</option>
{% for cust in customer %}
<option value="{{cust.account_number}}">{{cust.name}}: {{cust.account_number}} : {{cust.balance}}</option>
{% endfor %}
</select>
<br>
<button type="submit" name="button">TRANSFER</button>
</form>
</div>
{% endblock %}
transfer function from views.py:
def Transfer(request):
customer = Customer.objects.all();
if request.method=="POST":
s_acc = request.POST.get('s_acc')
amt = request.POST.get('amt')
r_acc = request.POST.get('r_acc')
print(s_acc)
print(amt)
print(r_acc)
amt = int(amt)
if((s_acc=='select')or(amt=='select')or(r_acc=='select')or(s_acc==r_acc)):
messages.warning(request,"Account not selected or both the accounts are same")
elif(amt<=0):
messages.warning(request,"Enter valid amount")
else:
for c in customer:
if(c.account_number == s_acc):
s_name = c.name;
if(amt>c.balance):
messages.warning(request,"Insufficient balance")
break
for x in customer:
if(x.account_number == r_acc):
r_name = x.name
r_bal = x.balance
break;
for c in customer:
if c.account_number == s_acc and r_acc!=s_acc and r_acc!= 'select' and amt<=c.balance and amt>0:
q1 = Transaction(sender_name = s_name, amount = amt, receiver_name = r_name )
q1.save()
acc_bal = c.balance - amt
q2 = Customer.objects.filter(account_number = s_acc).update(balance = acc_bal)
q2.save()
acc_bal = r_bal+amt
q3 = Customer.objects.filter(account_number = r_acc).update(balance = acc_bal)
q3.save()
messages.success(request,"Transfer Complete")
return redirect('tranfer_list')
return render(request,'bank/transaction.html',{'customer':customer})
urls.py
from django.urls import path
from bank import views
urlpatterns = [
path('',views.AboutView.as_view(),name = 'about' ),
path('about/', views.AboutView.as_view(),name = 'about'),

Thanks in advance :)
I'm trying to pass the selected id to controller using a route. But nothing happen shown at another blade file. Here, is my code
my blade contain that script
$("#state").on("change", function() {
var id = $(this).val();
console.log(id)
var cuid = document.getElementById("cu").value;
console.log(cuid)
});
state select
<div class="col-md-12 form-group" id="stateBranch">
<label for="sm" class="control-label">{{ __('messages.state') }}</label>
<select name="state" id="state" class="input-sm form-control">
<option value="">{{ __('messages.select') }}</option>
#if(!empty(request()->session()->get('stateList')))
#foreach(request()->session()->get('stateList') as $state)
<option value="{{ $state->st_state_code }}">{{ $state->st_state_desc }}</option>
#endforeach
#endif
</select>
</div>
cu select
<div class="col-md-12 form-group" id="custbranchreport">
<label for="sm" class="control-label">{{ __('messages.module.customer') }}<span class="compulsory"> * </span></label>
<select name="cu" id="cu" class="input-sm form-control" onchange="">
<option value="">{{ __('messages.select') }}</option>
#if(!empty($custList))
#foreach($custList as $cu)
<option value="{{ $cu->cu_customer_ID }}">{{ $cu->cu_customer_Shortname }}-{{ $cu->cu_customer_Name }}</option>
#endforeach
#endif
</select>
<input id="hid" type="hidden" name="hid" value=""/>
</div>
open new window route via onclick
<a class="btn btn-sm btn-default pull-right" type="button" title="Search Branch" onclick="openNewWindow('{{ route('reporting.branchCheckBoxList', ['cu' ,'state']) }}')" ><i class="fa fa-hand-o-up"></i> Choose Branch</a>
routes/web.php
Route::get('reporting/branchCheckBoxList/{cuid}/{stid?}','GenReportController#branchCheckBoxList')->name('reporting.branchCheckBoxList');
Controller
public function branchCheckBoxList(Request $request) {
$cuid = $request->get('cuid');
$stid = $request->get('stid');
return view('report.BranchCheckBoxList', compact('cuid','stid'));
}
You cannot used request in your method arguments considering that you are using a get request in your route, to access those parameters change your controller to this.
public function branchCheckBoxList($cuid, $stid = '') {
$cuid = $cuid;
$stid = $stid;
return view('report.BranchCheckBoxList', compact('cuid','stid'));
}
$(document).on('change','#cu',function(){
{
var state = $('#state option:selected').val();
var cu = $('#cu option:selected').val();
var viewurl = '{{ route("admin.booking.view", [":state",":cu"]) }}';
viewurl = viewurl.replace(':state',state );
var finalurl = viewurl.replace(':cu',cu );
$('a.btn').attr('href',finalurl);
});
and in you route
Route::get('reporting/branchCheckBoxList/{cuid}/{stid?}','GenReportController#branchCheckBoxList')->name('reporting.branchCheckBoxList');
and final in your controller
public function branchCheckBoxList($cuid, $stid = '')
{
$cuid = $cuid;
$stid = $stid;
return view('report.BranchCheckBoxList', compact('cuid','stid'));
}
I wanna put json's data to form.I wrote in index.html

document.addEventListener("DOMContentLoaded", showSex);
for (var i = 0, e = document.querySelectorAll(".form-horizontal select"); i < e.length; i++) {
e[i].addEventListener("change", showSex);
}
</script>
Now REGIST button cannot be sent,so I cannot regist these data.Why does such thing happen?I wanna put var sex data to regist in form.How should I fix this?
how can i sent js data to python?is it impossible?I think I should convert javascript data to python one,but I cannot understand how to do it.
