When you look database image, same numbers but different id's. How can i insert data to same id with two form fields.
This is create_normal.html
Here is the database
Here is my codes.

I found another way there is no need javascript. Actually i wanna make multiple forms and each datas must belong to one register. And sometimes one register can be own multiple datas. After all searching i found another way to make my project. I made a model with a primary key and then i give foreignkey and onetonefield to other models. Everything solved.
Here is the full project code: https://github.com/eseymenler/demo2

How to change message design in the real time chat

I have real time chat in the project, where i have two types of users: students and teachers. I want to change design of teacher messages. I tried to change consumers.py and tried to work with template but it didn't work. I think that we can do that, if we'll work with consumers.py. Who knows how to implement that?
models.py
class CustomUser(AbstractUser,mixins.GuardianUserMixin):
email = models.EmailField(_('email_address'), unique=True, name='email')
username = models.CharField(_('username'), unique=True, max_length=128)
is_student = models.BooleanField(default=False)
is_teacher = models.BooleanField(default=False)
first_name = models.CharField(max_length=255)
last_name = models.CharField(max_length=255)
USERNAME_FIELD = 'email'
REQUIRED_FIELDS = ['username']
objects = UserManager()
consumers.py
class Consumer(WebsocketConsumer):
def connect(self):
self.room_name=self.scope['url_route']['kwargs']['room_name']
self.room_group_name='chat_%s' % self.room_name
self.name = self.scope['user'].username
if self.scope['user'].is_anonymous:
self.send({'close':True})
else:
async_to_sync(self.channel_layer.group_add)(
self.room_group_name,
self.channel_name
)
async_to_sync(self.channel_layer.group_send)(
self.room_group_name,
{
"type":"chat_message",
"message":self.name+" Joined Chat "
}
)
self.accept()
def disconnect(self, code):
async_to_sync(self.channel_layer.group_send)(
self.room_group_name,
{
"type":"chat_message",
"message":self.name+" Left Chat"
}
)
async_to_sync(self.channel_layer.group_discard)(
self.room_group_name,
self.channel_name
)
def receive(self, text_data=None, bytes_data=None):
text_data_json=json.loads(text_data)
message=text_data_json['message']
async_to_sync(self.channel_layer.group_send)(
self.room_group_name,
{
'type':'chat_message',
'message':self.name+" : "+message
}
)
def chat_message(self,event):
message=event['message']
self.send(text_data=json.dumps({
'message':message
}))
template
<div class="ui form">
<div style="height:400px;width:100%;overflow-y:scroll" id="div_data"></div>
<input type="text" name="message" id="message" placeholder="Message" style="padding:10px;width:100%; border-radius: 0px;">
<script>
var roomName='{{ room_name }}';
var personname='{{ request.user.username }}';
var chatSocket=new WebSocket('ws://'+window.location.host+'/ws/chat/'+roomName+'/');
{% if request.user.is_anonymous %}
window.location.pathname = '{% url 'users:login' %}'
{% endif %}
chatSocket.onmessage=function(e){
var data=JSON.parse(e.data)
var message=data['message']
var div=document.querySelector("#div_data");
div.innerHTML+='<br><img class="ui avatar image" style="margin-left:2px;" src="{{user.profile.get_picture}}"><a style="padding:10px; margin-bottom:8px; " class="ui left pointing grey basic label">'+message+'</a>';
console.log(e)
}
chatSocket.onclose=function(e){
var data=JSON.parse(e.data)
console.log(data)
var message=data['message']
var div=document.querySelector("#div_data");
div.innerHTML+='<br><img class="ui avatar image" src="{% static "img/tom.jpg" %}"><a style="padding:10px; margin-bottom:8px;" class="ui right pointing teal basic label">'+message+'</a>';
}
document.addEventListener("keydown", function(event){
if(event.which == 13){
var message=document.querySelector("#message").value;
if(message.length == 0){
return false
}else{
chatSocket.send(JSON.stringify({'message':message}))
document.querySelector("#message").value=''
}
}
})
</script>

Just add a key "teacher":True or something like that to sent dictionary when a teacher sends.
You have to add some logic somewhere to know if the user is a teacher
def chat_message(self,event):
message=event['message']
dict_to_send = {'message':message}
if self.name in teachers_list:
dict_to_send['teacher'] = True
self.send(text_data=json.dumps(
dict_to_send
))
And then in js:
const data = JSON.parse(e.data);
if(data.teacher){
//this style
{
else{
//that style
}

Django ValidationError after javascript modifies the choice field

I'm working on a job scheduling app for a REST API and I've created a Tasks, Nodes, URL, Adom, BaseOptions, and Jobs tables in Django. The BaseOptions have a foreign key for src_adom and dst_adom and the Jobs have foreign keys for the Task, src_node, dst_node, url and baseOptions. I didn't use a ModelForm but a generic Form instead and just loaded up the initial values and choices for all the fields I need in order to process a job. I did that because I couldn't figure out how to make the form change when the user selects a different node and want to change the select field for the corresponding adoms. I'm using javascript to detect a new node and changing the select field with the appropriate adoms for that node. I get a validation error if I change the initial source and/or destination node and modify the adom selection list. I know it is because my list of choices have changed from what I initially rendered the form with.
Is there a way to change the choices associated with a ChoiceField during the "clean" method? I can't seem to find that in the documents or digging through the Django code on github.

I must confess I didn't go through all the code (it's quite a lot), but at a first glance it looks to me as you should move the initialization of your choices (intTasks, initNodes...) into the __init__ method of your FormClass (ScheduleJobForm).
Because you want the code to be run when you instantiate the class, not when you load the module, right?
So:
class ScheduleJobForm(forms.Form):
selected_node_type = forms.CharField(initial=selectedNodeType, widget=forms.HiddenInput)
task = forms.ChoiceField(choices=initTasks)
# further fields
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
# initialize initNodes and the rest
self.fields["src_node"]=initNodes
# and resp.
The form does not care about Javascript, as it is instantiated in the post request after all the Javascript magic on the frontend.
So there doesn't have to (and cannot) be any interaction between Javascript and your form.

I was able to figure out how to dynamically change the choices by using the getter and setter property of ChoiceField (see github repo).
The change I made was in the ScheduleJobForm view. I added these additional lines before calling 'is_valid':
print("Got a POST request, checking for valid...")
print("Fix the choices in the ADOMs first.")
src_nodeID_name = form['src_node'].value()
dst_nodeID_name = form['dst_node'].value()
src_nodeID = src_nodeID_name.split('.')[0]
dst_nodeID = dst_nodeID_name.split('.')[0]
srcAdoms = []
for adom in Adom.objects.all().filter(fmg_id=src_nodeID).order_by('id'):
adomChoice = adom.id, adom.name
srcAdoms.append(adomChoice)
dstAdoms = []
for adom in Adom.objects.all().filter(fmg_id=dst_nodeID).order_by('id'):
adomChoice = adom.id, adom.name
dstAdoms.append(adomChoice)
form.fields['src_adom'].choices = srcAdoms
form.fields['dst_adom'].choices = dstAdoms
For efficiency, I should probably check changed_data and see if the ADOM's have actually changed or not.

I want to use Django template language with JavaScript syntax

So, I want to get user input from my form (addDatabase.html) and display output of what they entered and let them download txt file with yaml formatted output (output.html).
It was working when I used Django's models.py using request.POST["fieldname"].
What I did was using JS to grab the tag of innerHTML and display out put of it
output.html JS code
var name = document.getElementById("name");
formContents += name.innerHTML + "\n";
var type = document.getElementById("type");
formContents += " " + type.innerHTML + "\n";
But my problem now is since I decided to use form.py using modelform instead of model.py. I don't know how to retrieve data from my model like i did from my model before.
output.html
<li id="type">type: {{ form.type}}</li>
<li id="vlanid">vlan_id: {{ form.vlan_id}}</li>
<li id="rdp">rdp: {{ form.rdp}}</li>
<li id="subnet">subnet:</li>
View.py (using Model from models.py)
def output(request):
Form_info.objects.all()
print("The button is clicekd")
name = request.POST["name"]
type = request.POST["type"]
vlan_id = request.POST["vlanid"]
rdp = request.POST["rdp"]
ip_master = request.POST["ipmaster"]
ip_backup = request.POST["ipbackup"]
vip = request.POST["gateway"]
nat_ip = request.POST["natip"]
cidr = request.POST["cidr"]
dns = request.POST["dns"]
dhcp = request.POST["dhcp"]
dhcp_pool_start = request.POST["dhcpstart"]
dhcp_pool_end = request.POST["dhcpend"]
form_info = Form_info(name=name, type=type, vlan_id=vlan_id, rdp=rdp, ip_master=ip_master, ip_backup=ip_backup,vip=vip, nat_ip=nat_ip, cidr=cidr, dns=dns, dhcp=dhcp, dhcp_pool_start=dhcp_pool_start,dhcp_pool_end=dhcp_pool_end)
form_info.save()
context = {
'form': form_info
}
return render(request, 'niro/output.html')
****View.py using modelform from forms.py****
This is my previous addDatabase function
def addDatabase(request):
# if this is a POST request we need to process the form data
return render(request, 'niro/addDatabase.html')
This is my current AddDatabase function
def addDatabase(request):
if request.method == 'POST':
form = YamlForm(request.POST)
if form.is_valid():
form.save()
# return HttpResponseRedirect('niro/output.html', {'form': form})
return HttpResponseRedirect('.', {'form': form})
else:
form = YamlForm()
return render(request, 'niro/addDatabase.html', {'form': form})
addDatabase.html
So post in here redirect to output.html function when the button is clicked
<div class="container">
<form action="{% url "output" %}" method="post">
{% csrf_token %}
<div class="row name">
<h3>NETWORK</h3>
</div>
<div class="row">
<div class="col-25">
<label for="">NAME:</label>
</div>
<div class="col-75">
<span class="text-danger" small>{{ form.name.errors }}</span>
{{ form.name }}
</div>
</div>
<div class="row">
<div class="col-25">
<label for="type">TYPE:</label>
</div>
<div class="col-75">
<span class="text-danger" small>{{ form.type.errors }}</span>
{{ form.type }}
.
.
.
.
<div class="row button container">
<div class="row button">
<button type="submit" value="submit">SUBMIT</button>
<button type="submit" value="submit">ADD MORE</button>
</div>
</div>
Models.py
BOOLEAN_CHOICES = (
(None, ' '),
(True, 'true'),
(False, 'false')
)
class Form_info(models.Model):
# all the columns
# example = models.CharField(null=Ture, unique=True)
name = models.CharField(max_length=50, null=True)
type = models.CharField(max_length=1, null=True)

nat_ip = models.CharField(max_length=15, blank=True)
# subnetmask might be devided into 2 different fields
cidr = models.CharField(max_length=18, null=True)
dns = models.CharField(max_length=15, null=True)
# boolean dropdown doesnt show
dhcp = models.CharField(null=True, max_length=10)
dhcp_pool_start = models.CharField(max_length=15, null=True)
dhcp_pool_end = models.CharField(max_length=15, null=True)
def get_absolute_url(self):
return reverse('niro:output', kwargs={'pk': self})
def __str__(self):
print("This is models.py")
return self.name + self.name + self.vlan_id + self.rdp + self.cidr + self.dhcp
So I want to modify my views.py on both functions so that way I can display userinput from the form and enables download function with existing JS code using Django modelform. Please help me!!

Error to create formset factory using django-dynamic-formset

I'm trying to use two formset_factory and django dynamic formsets in the same view, but I'm getting this error
[DOM] Found 2 elements with non-unique id #id_form-TOTAL_FORMS:
When I try to put a prefix on the second form it just generates one id then if add more than one item it will save the last item.
I would like to know how to fix this problem and why it happened ?
thanks in advance.

my formset.js file
$('.link-formset').formset({

});

formsets use #id_form-TOTAL_FORMS (and a few other things) to see how many forms there are and were initialy.
If you want to display more than one formset on a single page you'll run into the problem that you end up with two of these objects with the same id. To solve this you can define a prefix for one (or both) of the formsets.
