I am trying something with django and i need clone the form elements.
I found some code, it works but it inserts the different table id. I wanna clone two form fields with js clone code. It clones and then post the fields, when i looked the database, i see two fields inserterd tho different ids. How can i fix this?
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
I'm making a website where you can post jobs to an 'explore page', and I was then wondering how I would go about making it so that when a job is posted to that 'explore page', that job will also be posted to a page where the person who posted the job can manage all of the jobs they have posted i.e. edit, delete. I can post jobs to the explore page but I need to find a way for the job to save to the 'employers' page

I hope I've given you enough information + code to answer my question. Sorry about the confusing wording of the title too, I struggled to put that sentence together.
The easiest way is to use ListView from django.views.generic.list.ListView
You may override get_queryset to get desired behaviour:
def get_queryset(self):
qs = super().get_queryset()
qs = qs.filter(user=self.request.user)
return qs
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.
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">

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!!
I'm working on a web app project. I had a problem with file upload. Then I realized that my team mate changed the default submit button in create_form.html. It works like in 5. and 6. and i need to collect file data as well.
What should I add to .js files to submit and save file?
forms.py
class DocumentUpload(forms.ModelForm):
class Meta:
model = Form
fields = ('file',)
models.py
class Form(TimeStampedModel, TitleSlugDescriptionModel):
author = models.ForeignKey(User, on_delete=models.CASCADE)
title = models.CharField(max_length=512)
is_final = models.BooleanField(default=False)
is_public = models.BooleanField(default=False)
is_result_public = models.BooleanField(default=False)
file = models.FileField(null=True, blank=True)
def __str__(self):
return self.title
def get_absolute_url(self):
return reverse('form-detail', kwargs={'slug': self.slug})
views.py

if request.method == 'POST':
user = request.user
data = ParseRequest(request.POST)
print(data.questions())
print(data.form())

parsed_questions = data.questions()
# tworzy formularz o podanych parametrach
formfile = DocumentUpload(request.POST, request.FILES or None)
if formfile.is_valid():
form = formfile.save(commit=False)
print(form)
form.author = user
form.title = parsed_form['title']
form.is_final = parsed_form['is_final']
form.is_result_public = parsed_form['is_result_public']
form.description = parsed_form['description']
form.save()
# zapisuje pytania z ankiety wraz z odpowienimi pytaniami

question = Question(form=form, question=d['question'])
question.save()
# dla kazdego pytania zapisz wszystkie opcje odpowiadania
for opt in d['options']:
option = Option(question=question, option=opt)
option.save()
return render(request, 'forms/form_form.html', {})
else:
form = DocumentUpload()
return render(request, 'forms/form_form.html', {'form': form})
