I'm new to Django and I have a problem that makes me quite confused. I have a page when users click to change profile, the corresponding page shows up and lets users update their profile. Here is my model:
from django.db import models
import os
from django.db import models
from django.contrib.auth.models import User
from django.conf import settings
from django.utils import timezone
from django.db.models.signals import post_save
from django.dispatch import receiver
# Create your models here.
class Account(models.Model):
user = models.ForeignKey(User, on_delete="CASCADE")
phone = models.CharField(max_length=18)
room = models.CharField(max_length=8)
dob = models.DateField(default=timezone.datetime.now())
active = models.BooleanField(default=True)
avatar = models.ImageField(upload_to='images/', default=os.path.join(settings.STATIC_ROOT, 'avatar.png'))
def __str__(self):
return self.user.username
Here are my forms:
class UserForm(forms.ModelForm):
first_name = forms.CharField(max_length=100,
widget=forms.TextInput(attrs={'class': 'uk-input', 'placeholder': 'Last Name'}))
last_name = forms.CharField(max_length=100,
widget=forms.TextInput(attrs={'class': 'uk-input', 'placeholder': 'Last Name'}))
class Meta:
model = User
fields = ['first_name', 'last_name', 'email']
class ProfileForm(forms.ModelForm):
class Meta:
model = Account
fields = ['phone', 'room', 'dob', 'active', 'avatar']
And I have my views.py like this:
def show_form(request):
user_basic_info = UserForm(request.POST)
form = ProfileForm(request.POST)
if form.is_valid() and user_basic_info.is_valid():
form.save() and user_basic_info.save()
messages.sucess(request, _('Your profile has been successfully updated'))
redirect('my_account')
else:
UserForm()
ProfileForm()
context = {
'user_basic_info': user_basic_info,
'form': form,
}
return render(request, 'my_account.html', context)
Here is my_account.html template:
{% extends 'base.html' %}
{% block title %}My account{% endblock %}
{% block breadcrumb %}
<li class="breadcrumb-item active">Update your information</li>
{% endblock %}
{% block content %}
<div class="row">
<div class="col-lg-6 col-md-8 col-sm-10">
<form method="post" novalidate>
{% csrf_token %}
{% include 'includes/form.html' %}
<button type="submit" class="btn btn-success">Save changes</button>
</form>
</div>
</div>
{% endblock %}
And forms.html:
{% load widget_tweaks %}
<table>
<div class="form-group">############
{{ user_basic_info }} ############# This displays first_name, last_name and email. Also the problem's here, I want to make 2 forms in one form with a better style like the form below.
</div>############
</table>
{% if form.non_field_errors %}
<div class="alert alert-danger" role="alert">
{% for error in form.non_field_errors %}
<p{% if forloop.last %} class="mb-0"{% endif %}>{{ error }}</p>
{% endfor %}
</div>
{% endif %}
{% for field in form %}
<div class="form-group">
{{ field.label_tag }} {% if form.is_bound %} {% if field.errors %} {% render_field field class="form-control is-invalid" %} {% for error in field.errors %}
<div class="invalid-feedback">
{{ error }}
</div>
{% endfor %} {% else %} {% render_field field class="form-control is-valid" %} {% endif %} {% else %} {% render_field field class="form-control" %} {% endif %} {% if field.help_text %}
<small class="form-text text-muted">
{{ field.help_text|safe }}
</small> {% endif %}
</div>
{% endfor %}
So when users want to change their profile, those fields first_name, last_name, email, phone, room, dob, active, avatar need to be displayed. But the first 3 fields belong to the User model and the rest fields are defined in my Account model. I want when users submit the form, those fields are linked together, e.g Account is an instance of User and that information is properly saved to the database in Account model (I have watched some tutorials but I still cannot properly do it). And when logging to the page, login authentication using User model, but when updating the profile it's Account model and User model, but there is no relationship between them, how can I fix all of those errors, thanks in advance.
you need to use OneToOne Relationship here since each user has only one and unique profile details. so in your models.py use :-
user = models.OneToOneField(User, on_delete=models.CASCADE)
If you use default user there is 4 way to extends it so here i give a link follow them,
if you use default user you need to use Usercreation form for Register because the user model have password encryption algorithmuse so when you use you user define form it will not store your password
follow instruction for extends user abstract base model
extends user using
registration form using usercreation form
Define view of save data
follow instruction for extends user using one to one
Create new model Profile and give one to one relationship
Create registration form usring model.formplus additional fields you want to take from user define in form class explicity
in view save form and add user reference in Profile model using create method
link:
extend user model
if you use usercreation form
go through i give link if you got error let me know

I want to display just one field from my form that I have created but I am getting 'Could not parse the remainder:' error
Here is my forms.py file
from django import forms
from .models import *
class ProductForm(forms.ModelForm):
class Meta:
model = Product
fields = ('prod_name', 'company', 'quantity', 'price', 'units', 'prod_type')
Here is my html file
{% extends 'base.html' %}
{% block body %}
<div class="container">
<form method="POST">
<br>
{% csrf_token %}
{% for field in form %}
{% if field.name=='units' %}
<div class ="form-form row">
<label for="id_{{field.name}}" class="col-2 col-form-label">{{field.label}}</label>
<div class ="col-10">
{{field}}
</div>
</div>
{% endif %}
{% endfor %}
<button type="submit" class="btn btn-primary" name="button">Update Sales</button>
</form>
</div>
{% endblock %}
I just want to display units in my webpage for this module that I am creating
I think you try to solve the problem on the wrong level. You can just construct a form with one field:
from django import forms
from .models import *
class UnitProductForm(forms.ModelForm):
class Meta:
model = Product
fields = ('units',)
If you need the other form as well, you can just create an extra one, with a different name, like here UnitProductForm.
Using a form with a subset of fields is not only easier to render. The form will not make modifications to fields of a model object if these are not specified, even if these items are passed in a (forged) POST request. So it makes it more safe to use as well.
If you want to display only prod_name field then you can do it:
{
from django import forms
from .models import *
class ProductForm(forms.ModelForm):
class Meta:
model = Product
fields = ('prod_name')
}
Displaying just one field can be controlled from the templates like:
{% extends 'base.html' %}
{% block body %}
<div class="container">
<form method="POST">
{% csrf_token %}
{{ form.units.label_tag }} /*Shows the label for the input field */
{{ form.units }} /*Shows the input field */
<button type="submit" class="btn btn-primary" name="button">Update Sales</button>
</form>
</div>
{% endblock %}
This is from the official documentation, found here.
Note that you will have to handle creation of the object in the backend, if you choose to display only certain fields like this.
I am using django-filter==2.1.0 for implementing search filter. I already implement it. But now i need to search by clicking checkbox not by search button. My codes are given below:
models.py
class Book(models.Model):
name = models.CharField(max_length=100)
publication = models.ForeignKey(Publication, on_delete=models.CASCADE)
filters.py
class BookFilter(django_filters.FilterSet):
publication = django_filters.ModelMultipleChoiceFilter(queryset=Publication.objects.all(),
widget= forms.CheckboxSelectMultiple)
class Meta:
model = Book
fields = ['publication']
views.py
def test_view(request):
book_list = Book.objects.all()
book_filter = BookFilter(request.GET, queryset=book_list)
temp = book_filter.form
return render(request, 'test.html', {'filter': book_filter})
template
{% extends 'base.html' %}
{% load widget_tweaks %}
{% block content %}
<form method="get">
{% for choice in filter.form.publication %}
<label>
{{ choice.tag }}
<span class="max-content-width">{{ choice.choice_label }}</span>
</label>
{% endfor %}
<button type="submit">Search</button>
</form>
<ul>
{% for book in filter.qs %}
<li>{{ book.name }}</li>
{% endfor %}
</ul>
{% endblock %}
It's working properly. But i want to add widget = forms.CheckboxInput(attrs={'onclick': 'this.form.submit();'}) in my filters.py for checkbox input. I don't understand how can i add another widget. Please help me to solve this problem.
Create a widget, write JavaScript script and use Media metaclass on widget to use it. After this just use your widget on your checkbox field.
I am getting error message the UnboundLocalError local variable 'Assumptions' referenced before assignment (after line else:). I wonder how is that even possible given that Assumptions is a model and is imported to the views.py. Any advise how to solve it would be highly appreciated. Also, I am trying to create multiple forms based on Assumptions modelform and save them into the database model Assumptions. Please advise if this code is the correct design pattern. Thank you.
views.py
from django.shortcuts import render
from .forms import modelformset_factory, AssumptionsForm
from .models import Assumptions
def get_assumptions(request):
if request.method == 'POST':
if 'name' in request.POST:
formset = modelformset_factory(Assumptions, form = AssumptionsForm, extra = 5)
if formset.is_valid():
print('valid form')
for form in formset:
print('Looping forms')
Assumptions = form.save(commit='False')
Assumptions.Name = 'name'
Assumptions.save()
else:
formset = modelformset_factory(Assumptions, form = AssumptionsForm, extra = 5)
return render(request, 'assumptions.html', {'formset': formset})
assumptions.html
<div class="form">
<form action="" method="post">
{% csrf_token %}
{{ formset.management_form }}
{{ formset.non_form_errors.as_ul }}
{% for name in ['A', 'B'] %}
<h1>var</h1>
<table id="formset" class="form">
{% for form in formset.forms %}
{% if forloop.first %}
<thead><tr>
{% for field in form.visible_fields %}
<th>{{ field.label|capfirst }}</th>
{% endfor %}
</tr></thead>
{% endif %}
<tr class="{% cycle 'row1' 'row2' %}">
{% for field in form.visible_fields %}
<td>
{# Include the hidden fields in the form #}
{% if forloop.first %}
{% for hidden in form.hidden_fields %}
{{ hidden }}
{% endfor %}
{% endif %}
{{ field.errors.as_ul }}
{{ field }}
</td>
{% endfor %}
</tr>
{% endfor %}
</table>
<input type="submit", name='name', value="save" />
{% endfor %}
</form>
</div>
forms.py
from django import forms
from django.forms import modelformset_factory, ModelForm
from .models import Assumptions
class AssumptionsForm(ModelForm):
class Meta:
model = Assumptions
fields = ['Worst', 'Base', 'Best']
exclude = ['Name']
models.py
from django.db import models
from django.forms import ModelForm
class Assumptions(models.Model):
Worst = models.FloatField(null=True, blank=True, default=None)
Base = models.FloatField(null=True, blank=True, default=None)
Best = models.FloatField(null=True, blank=True, default=None)
Name = models.TextField(null=True, blank=True, default=None)
You are shadowing the imported Assumptions name by assigning a new value to it here:
Assumptions = form.save(commit='False')
You should use a different name for your model instance. The usual practice is to use a lowercase name, i.e.
assumptions = form.save(commit='False')
assumptions.Name = 'name'
assumptions.save()
What I'm trying to accomplish is to extend UserCreationForm to add an e-mail field for each user when they sign- up. Currently I have a form from UserCreationForm with username and password but no e-mail. I extend it with the forms.py file and implement it in my views.py. But when I run tests and look at the signup page the e-mail field is not found.
views.py:
from django.shortcuts import render, redirect
from django.contrib.auth.forms import UserCreationForm
from django.contrib.auth import login as auth_login
from .forms import SignUpForm
# Create your views here.
def signup(request):
if request.method == 'POST':
form = SignUpForm(request.POST)
if form.is_valid():
user = form.save()
auth_login(request, user)
return redirect('index')
else:
form = SignUpForm()
return render(request, 'signup.html', {'form': form})
forms.py:
from django import forms
from django.contrib.auth.forms import UserCreationForm
from django.contrib.auth.models import User
class SignUpForm(UserCreationForm):
email = forms.CharField(max_length = 254, required = True, widget = forms.EmailInput())
class Meta:
model = User
fields = ('username', 'email', 'password1', 'password2')
form.html:
{% load widget_tweaks %}
{% for field in form %}
<div class="form-group">
{{ field.label_tag }}
{% if form.is_bound %}
{% if field.errors %}
{% render_field field class="form-control is-invalid" %}
{% for error in field.errors %}
<div class="invalid-feedback">
{{ error }}
</div>
{% endfor %}
{% else %}
{% render_field field class="form-control is-valid" %}
{% endif %}
{% else %}
{% render_field field class="form-control" %}
{% endif %}
{% if field.help_text %}
<small class="form-text text-muted">
{{ field.help_text|safe }}
</small>
{% endif %}
</div>
{% endfor %}
Now, when I actually go to the sign in page it only presents Username and password fields. However, when I refresh the page or send an invalid form, the e-mail field shows up when the form reloads. It's confirmed that the field is not showing up on initial load when I run tests and get an assertion error:
AssertionError: 0 != 1 : Found 0 instances of 'type="email"' in response (expected 1)
Hi i used formsets in generic FormView like this:
class RequestRecommendationView(FormView):
template_name = "account/stepfour.html"
form_class = formset_factory(StepFourForm)
def form_valid(self,form):
print form.is_valid()
cleaned_data = form.cleaned_data
# return redirect(reverse("some_url_name"))
form for formset_factory is like this:
class StepFourForm(forms.Form):
contact_person = forms.CharField(required=True)
email = forms.EmailField(required=True)
company = forms.CharField(required=True)
request_message = forms.CharField(required=True)
my html structure is like this:
<div style="padding-top:100px;padding-left:10px;">
<h4> Request a Recommendation </h4>
<form method="post" action="">
{% csrf_token %}
<table id="myForm">
<tbody>
{% for f in form %}
{% for field in f %}
<tr>
<td>{{field.label_tag}}</td>
<td>{{field}}</td>
{% for error in field.errors %}
<td><span>{{ error }}</span></td>
{% endfor %}
</tr>
{% endfor %}
{% endfor %}
</tbody>
</table>
<button class="btn btn-primary btn-xlarge" type="submit" name="submit">Request Now</button>
{{ form.management_form }}
</form>
</div>
Then i used django-dynamic-formset (https://code.google.com/p/django-dynamic-formset/)
to add/remove extra forms through these:
<script type="text/javascript">
$(function() {
$('#myForm tbody').formset();
})
</script>
the problem is:
if i leave the form empty,(every field is required), it manages to get to form_valid() of my class-view (though it should not), if i fill one of the fields (leaving others unfilled), it displays the errors associated message successfully. why is this happening ? what should i do to fix it ? is providing form_class a formset is behind all of this ?
This question has been asked 6 years ago, I found it because i faced the same issue, since it is unanswered, I'll provide the solution i found.
according to the documentation to validate a minimum of forms, you have to provide a min_num and set validate_min=True in the formset_factory:
formset = formset_factory(your_form, min_num=2, validate_min=True, extra=2)
