I am having a problem with Django forms. I am currently using the request.POST to validate the POST within views.
I want to send inputed-data(radio type) from my template with the same name.
In my template.py:
<form method="post" action="{% url 'app:AnsSubmission' %}">
{% csrf_token %}
{% for i in Exam %}
<div class="form-group col-xl-12">
<label>{{ i.question }}</label>
<div class="radio">
<label><input type="radio" class="mx-2" name="givenAns" array_column="{{ i.pk }} value="True" required>True</label>
</div>
<div class="radio">
<label><input type="radio" class="mx-2" name="givenAns" array_column="{{ i.pk }} value="False" required>False</label>
</div>
</div>
{% endfor %}
<button type="submit" class="btn btn-primary">Submit</button>
</form>
And willing to fetch these data in views.py like:
givenAns_list = request.POST.getlist('givenAns')
for i in givenAns_list:
this_givenAns = givenAns_list[i]
But the problem here is this radio type input field doesn't take value for the same name(not as a list I wish). If I select answer of 2nd question, the 1st one's selection is unselected.
Please suggest how can I fix this?

I am trying to extend the UserCreationForm using a Bootstrap layout style for the field username. After the input tag in the registration form, I would like to add a div element like an example that I have readapted from the Bootstrap page: i.e. suggesting the user to enter the same username as the company domain.
Let's focus to the bare minimum. The form readapted from Bootstrap is:
<form class="row gy-2 gx-3 align-items-center method="POST" action="{% url 'register' %} ">
<div class="col-auto">
<div class="input-group">
<input type="text" name="username" class="form-control" placeholder="your.username" id="id_username">
<div class="input-group-text">#company.domain.com</div>
</div>
</div>
<div class="col-auto">
<button type="submit" class="btn btn-primary">Submit</button>
</div>
</form>
Which produces the following:
For the moment, I am using only {{form.as_p}} in my html template file:
<form class="row gy-2 gx-3 align-items-center method="POST" action="{% url 'register' %} ">
{{form.as_p}}
<div class="col-auto">
<button type="submit" class="btn btn-primary">Submit</button>
</div>
</form>
And I don't know how to add the <div class="input-group-text">#company.domain.com</div> part embedded in a <div class="input-group">...</div> block.
My actual forms.py is a bit more complex, but readapted for this minimum example it contains the widget attributes as follows:
class SignupForm(UserCreationForm):
username = forms.CharField(label="",
widget=forms.TextInput(attrs={'class': 'form-control', 'placeholder': 'your.username'}))
class Meta:
model = User
fields = (
'username',
)
Without additional libraries, is there a way to extend the widget attributes? Is it even possible to use {{form.as_p}} as I am currently doing or should I use another method?
If you want to use only {{ form.as_p }} with bootstrap then you need to install django-bootstrap.
Install it using pip:
pip install django-bootstrap4
After installation, add it in INSTALLED_APPS in settings.py file.
INSTALLED_APPS = [
'bootstrap4',
]
And in templates, you need to load it.
{% load bootstrap4 %}
{% bootstrap_messages %}
<form class="row gy-2 gx-3 align-items-center method="POST" action="{% url 'register' %} ">
{% csrf_token %}
{% bootstrap_form form %} # added `form` here. we don't need to use with as_p.
<div class="form-group">
<button type="submit" class="btn btn-primary">Submit</button>
</div>
</form>
This is the way you can use bootstrap along with {{ form.as_p }}
OR
Try another way:
Simply you can use {{ form.username }} inside an input tag in template.
For Example:
<input type="text" value="{{ form.username }}">
<form class="row gy-2 gx-3 align-items-center method="POST" action="{% url 'register' %} ">
<div class="col-auto">
<div class="input-group">
<input type="text" name="username" class="form-control" placeholder="your.username" id="id_username" value="{{ form.username }}"> #Added here
<div class="input-group-text">#company.domain.com</div>
</div>
</div>
<div class="col-auto">
<button type="submit" class="btn btn-primary">Submit</button>
</div>
</form>
How do i allow to display a particular form content after the user clicks on checkbox Yes or No
for e.g.if the user clicks on yes checkbox display the form to be filled if user clicks No display another form part to be filled
I want to add it here like in my applyonline.html
{% extends "pmmvyapp/base.html" %}
{% load crispy_forms_tags %}
{% load static %}
{% block content%}
<div class="col-md-8">
<form method="post" action="/add_aganwadi/">
{% csrf_token %}
<div class="form-group">
<div class=" mb-4">
<h6><u>Please Fill up the details below (Note that all the fields are required)</u></h6>
</div>
<legend class="border-bottom mb-4" ,align="center">Beneficiary Details</legend>
<label for="formGropuNameInput">Does Beneficiary have a Driving License Card?*</label>
<div class="form-check form-check-inline">
{% if..... %}
<input class="form-check-input" type="checkbox" id="inlineCheckbox1" value="option1">
<label class="form-check-label" for="inlineCheckbox1">Yes</label>
{% else %}
</div>
<div class="form-check form-check-inline">
<input class="form-check-input" type="checkbox" id="inlineCheckbox2" value="option2">
<label class="form-check-label" for="inlineCheckbox2">No</label>
</div>
</div>
{% endif %}
<button type="submit" class="btn btn-primary" style="margin-bottom:10px ">Submit</button>
</form>
</div>
{% endblock %}
I want to know if I can use the if statement to achieve this and if so how?
if you don't have any problem in including angularjs in form page and radio button instead of check box this below sample code image i used previously will help you
I have used django allauth for user registration and login. I have used the {{ form.has_errors }} in template to show an error but the error is not displayed in the template. What might be the reason for not showing an error in the template?
The code from allauth login.html(account/login.html)
{% block content %}
<div class="login-box">
<div class="row">
<div class="col-xs-12 col-sm-12 col-md-6 col-md-offset-3 login-area">
<span class="error">
{% if form.has_errors %}
<p>Your username and password didn't match. Please try again.</p>
{% endif %}
</span>
<div class="panel panel-default">
<div class="panel-heading login-header">{% trans "Sign In" %}</div>
<div class="panel-body">
<form class="login" method="POST" action="{% url 'account_login' %}">
{% csrf_token %}
<div class="form-group form-group-lg">
<label for="emailAddress">Email address</label>
<input type="email" class="form-control" id="emailAddress id_login" name="login" placeholder="Email">
</div>
<div class="form-group form-group-lg">
<label for="password">Password</label>
<input type="password" class="form-control" id="password id_password" name="password" placeholder="Password">
</div>
<div class="form-group">
{% if redirect_field_value %}
<input type="hidden" name="{{ redirect_field_name }}" value="{{ redirect_field_value }}" />
{% endif %}
</div>
<button class="btn-block signin-btn btn-sm btn-primary pull-right m-t-n-xs" type="submit">{% trans "Sign In" %}</button>
</form>
</div>
<div class="panel-footer">
<a class="button secondaryAction" href="{% url 'account_reset_password' %}">{% trans "Forgot Password?" %}</a>
</div>
</div>
</div>
</div>
</div>
{% endblock %}
Try this one. Errors raised by the form which is not attached to field are stored in non_field_errors
{% if form.non_field_errors %}
<ul class='form-errors'>
{% for error in form.non_field_errors %}
<li>{{ error }}</li>
{% endfor %}
</ul>
{% endif %}
or if you want to display in your way try this one
{% if form.errors %}
<p>Your username and password didn't match. Please try again.</p>
{% endif %}
Seems to be a misunderstanding of has_error
his method returns a boolean designating whether a field has an error
with a specific error code. If code is None, it will return True if
the field contains any errors at all.
Coupled with the fact that you are rendering the form manually. Generally there are two types of form errors, non field errors and errors associated with each field (when their validation fails). The above method accepts a field name as a parameter and returns true if the field has failed validation.
You have several options, including continuing with your current approach but checking for form.errors instead of form.has_error or displaying the error with each field separately.
I have an app which reads the questions from database and display them .I need to enter the response to it and save it back in the database.Is it possible to do it without using forms
My HTML section
<form id="survey" method="post" action="/Survey/restricted/" class="form col-md-12 center-block">
{% csrf_token %}
{% for b in obj1 %}
<textarea class="form-control">{{b.question}}</textarea>
<textarea class="form-control" rows="3" name="response1" width="100%;">{{b.response}}</textarea>
{% endfor %}
<input type="submit" name="submit" class="btn btn-success" value="Submit Response" />
</form>
I tried to access the data after entering the response and submitting using
res=request.POST.get('response1')
but it returns none
You should move the response1 field outside the loop, but then it should be passed as a separate field (e.g. response), not as part of the obj1 list of questions (or not passed at all if keeping the previous answer is unnecessary).
<form id="survey" method="post" action="/Survey/restricted/" class="form col-md-12 center-block">
{% csrf_token %}
{% for b in obj1 %}
<textarea class="form-control">{{b.question}}</textarea>
{% endfor %}
<textarea class="form-control" rows="3" name="response1" width="100%;">{{response}}</textarea>
<input type="submit" name="submit" class="btn btn-success" value="Submit Response" />
</form>
Also, I think the questions should not be editable (i.e. disabled, or not a textarea altogether)
Okay, so I've created a simple purchase form which makes use of some custom form fields. I've rendered a simple form to test if it works properly, and it does, as shown below.
<form id="category_form" method="post" action="/purchase/">
{% csrf_token %}
{% for hidden in form.hidden_fields %}
{{ hidden }}
{% endfor %}
{% for field in form.visible_fields %}
{{ field.errors }}
{{ field.help_text }}
{{ field }}
{% endfor %}
<input type="submit" name="submit" value="Make purchase" />
</form>
Now, I wish to style it to Bootstrap 3. I've managed to style it with no problems using the django widget tweaks package. However, when I submit the form, I get this error 'NoneType' object has no attribute 'replace' I've tried it without the widget tweaks and I still get the same error.
Any ideas why this may be the case? The original form works fine unstyled, but as soon as I style it I get the above error. Now if my understanding is correct, Django takes one field and styles corresponding fields the same, but, some of my field types are different. i.e. dropdowns and text boxes, which can't be styled the same way. I'm not sure what the best way around this is.
views.py
def checkout(request):
if request.method == 'POST':
form = PurchaseForm(request.POST)
if form.is_valid():
form.save(commit=True)
return index(request) # Change this to point to the confirmation page
else:
print (form.errors)
else:
form = PurchaseForm()
return render(request, 'ticket/checkout.html', {'form': form})

I would suggest using the python package django-bootstrap3 to style your forms. It can be found at https://github.com/dyve/django-bootstrap3
Hope this helps!
I am not sure whether I understand your question correctly. However I noticed that 1. there seems no tag in your form.
2. maybe you can use plain html instead of other tag( {{ form.security_code|attr:"id:cvv-number"|attr:"name:cvv-number" ****}} ), such as
3. to validate form, you may try to write something like :
{% if form.password.errors %}
{% for error in form.password.errors %} {{ error}} {% endfor %} {% endif %}
Hope you figure out this problem as soon as possible.
