I have created a custom html template with basic checkboxes to select a value and return the value to the Django admin page.
I have done a 100 times before, but now the value of the selected superprofile does not get captured by the variable "selected_value" in the admin.py
The if statement "if request.method == 'POST':" is getting triggered but i keep getting the value of "selected_value" as none
Driving me crazy, I cannot find anything wrong in the code
The Html template
{% extends "admin/base_site.html" %}
{% load i18n admin_urls static admin_modify %}
{% block extrahead %}
{{ media }}
{% endblock %}
{% block content %}
<form class="change_superprofile_parent_form" method="POST" class="change_superprofile_parent_form">{% csrf_token %}
{% for superprofile in superprofiles %}
<input type="checkbox" name="superprofile_selected" {{ superprofile.checked }} value="{{ superprofile }}"> {{ superprofile }}<br>
{% endfor %}
<input type="submit" value="Submit">
</form>
{% endblock %}
Django admin.py
def change_superprofile_parent(self, request, queryset):
"""
Action to change the superprofile of the selected
"""
queryset = queryset.values_list("id", flat=True)
if request.method == 'POST':
selected_value = request.POST.getlist('superprofile_selected')
eligible_superprofiles = SuperProfile.objects.filter(status='Active')
return render(
request, 'admin/auth/user/change_superprofile_parent.html', context={
'superprofiles': eligible_superprofiles,
}
)

This the html code
def staffApply(request,pk):
if request.method == 'POST':
selected_domestic_works = request.POST.getlist('domestic_works')
formsets = []
if 'cook' in selected_domestic_works:

if 'driver' in selected_domestic_works:
formsets.append(DriverForm(request.POST,prefix='driver'))
print(formsets)
return render(request, 'staffApply2.html', {'formsets': formsets})

enter code here
This is my views.py
class CookingForm(ModelForm):
food_cooked=(('veg','veg'),
('non-veg','non-veg'),
('both','both')
)
class Meta:
model = Cook
fields = '__all__'
exclude=['user']
widgets={
'food_cooked':forms.widgets.RadioSelect(),
'type_of_cuisine':forms.widgets.CheckboxSelectMultiple()
}
This is my forms.py
I am getting the fields to type. But I am not getting hte label for those fields. Please help me fix this.
class Cook(models.Model):
food_cooked=(('veg','veg'),
('non-veg','non-veg'),
('both','both')

('SouthIndian','SouthIndian'),
('Chettinadu','Chettinadu'),
('Chinese','Chinese'),
)
user=models.ForeignKey(User,on_delete=models.CASCADE)
food_cooked=models.CharField(choices=food_cooked,max_length=30)
type_of_cuisine=models.CharField(choices=type_of_cuisine,max_length=30)
experience=models.IntegerField()
wages_expected=models.IntegerField()
dishwashing_flag=models.BooleanField()
wages_for_dishwashing=models.IntegerField(null=True)
desc=models.TextField(max_length=200)
This is my models.py
You have one extra loop, with the wrong naming so you cannot access {{ field.label }} on your loops its like you are trying something like {{ form.field.attribute.label }}, the correct way would be the following:
{% for form in formsets %}
<form method="post">
{% for field in form %}
<div>
<label for="{{ field.auto_id }}">{{ field.label }}</label>
{{ field }}
{% for error in field.errors %}
<p>{{ error }}</p>
{% endfor %}
</div>
{% endfor %}
<input type="submit" value="Submit">
</form>
{% endfor %}
That being said, you can also use Django form rendering options, instead of doing it manually.
{% for form in formsets %}
<form method="post">
{{form.as_p}}
<input type="submit" value="Submit">
</form>
{% endfor %}

I have a form with 2 CharFields. Both have label="xyz".
If I use this form in a formset, the lables are not shown in the HTML
I have tried looking at the rendered HTML and the label is missing. I have tried just a form and that works.
Forms:
class WindingVoltsSpecifier(forms.Form):
winding_name = forms.CharField(max_length=20, label="Winding name")
voltages = forms.CharField(max_length=20, label="Voltages")
View:
def add_mains_transformer_primary_configs(request):
# Add a new config
# Create the formset, specifying the form and formset we want to use.
# From https://whoisnicoleharris.com/2015/01/06/implementing-django-formsets.html
VoltsSpecifierFormSet = formset_factory(WindingVoltsSpecifier)
if request.method == 'POST':
pass
else:
mt_config_form = MainsTransformerConfiguration()
volts_formset = VoltsSpecifierFormSet()
context = {
'mt_config_form' : mt_config_form,
'volts_formset' : volts_formset,
}
return render(request, 'designer/mains_configs.html', context)
Template:
{% extends 'designer/base.html' %}
{% load crispy_forms_tags %}
{% block title %}configuration{% endblock %}
{% block content %}
{% load static %}
<h1>Configuration</h1>
<form method="post">
{% csrf_token %}
{{ mt_config_form|crispy }}
{{ volts_formset.management_form|crispy }}
{% for volts_form in volts_formset %}
<table>
{% for form in volts_form %}
{{ form }}
{% endfor %}
<table>
<!--<div class="volts-formset">
{{ volts_form.winding_name }}
{{ volts_form.voltages }}
</div>
-->
{% endfor %}
{% if volts_formset.non_form_errors %}
{% for error in volts_formset.non_form_errors %}
{{ error|escape }}
{% endfor %}
{% endif %}
<input type="submit" value="Update Profile" class="button" />
</form>
<script>
$('.volts-formset').formset({
addText: 'add winding',
deleteText: 'remove'
});
</script>
{% endblock %}
I would expect the label to be beside the field.
Labels are not rendered with fields, you will have to do a {{ FIELD.label_tag }}.
It will be something like this:
<table>
{% for field in volts_form %}
{{ field.label_tag }}
{{ field }}
{% endfor %}
<table>
More info: Looping over the forms fields - Django documentation
Hope this solution to works!
{% for field in volts_forms %}
{{ field.name}} <!-- label name -->
{{ field }}<!-- ex. input -->
{% endfor %}
I am trying to call a python view method res() on django template but its not getting call.
This is my View
class make_incrementor(object):
def __init__(self, start):
self.count=start
def __call__(self, jump=1):
self.count += jump
return self.count
#property
def res(self):
self.count =0
return self.count
def EditSchemeDefinition(request, scheme_id):
iterator_subtopic = make_incrementor(0)
scheme_recs = scheme.objects.get(id=scheme_id)
view_val = {
'iterator_subtopic': iterator_subtopic,
"scheme_recs": scheme_recs,
}
return render(request, "edit.html", view_val)
I am Trying to Increment the count and later resetting it to 0 after a level But its reset method is not getting call from the Django template.
This is my edit.html page
<td id="subTopic" class="subTopic">
{% for strand in scheme_recs.stand_ids.all %}
{{ iterator_subtopic.res }}
{% for sub_strand in strand.sub_strand_ids.all %}
{% for topic in sub_strand.topic_ids.all %}
{% for subtopic in topic.sub_topic_ids.all %}
<input id="subTopic{{ iterator_subtopic }}" class="len"
value="{{ subtopic.name }}">
<br>
{% endfor %}
{% endfor %}
{% endfor %}
{% endfor %}
</td>
my {{ iterator_subtopic.res }} is not getting the call and the value of iterator_subtopic is not get set to 0 again. The Function and its call is working fine on Terminal but not rendering in django template.
Please correct me where i am doing wrong.
Thanks in advance.
Since your make_incrementor class has a __call__ method, I believe that {{ iterator_subtopic.res }} will first call iterator_subtopic(), which will return the count integer. It will then try to access the res attribute of the count integer (which doesn't exist), so it will output the empty string ''.
I simply modify my make_incrementor class methods like:-
class make_incrementor(object):
count = 0
def __init__(self, start):
self.count = start
def inc(self, jump=1):
self.count += jump
return self.count
def res(self):
self.count = 0
return self.count
def EditSchemeDefinition(request, scheme_id):
iterator_subtopic = make_incrementor(0)
scheme_recs = scheme.objects.get(id=scheme_id)
view_val = {
'iterator_subtopic': iterator_subtopic,
"scheme_recs": scheme_recs,
}
return render(request, "edit.html", view_val)
Later in my django template I called its method like:-
<td id="subTopic" class="subTopic">
<p hidden value="{{ iterator_subtopic.res }}"></p>
{% for strand in scheme_recs.stand_ids.all %}
{{ iterator_subtopic.res }}
{% for sub_strand in strand.sub_strand_ids.all %}
{% for topic in sub_strand.topic_ids.all %}
{% for subtopic in topic.sub_topic_ids.all %}
<input id="subTopic{{ iterator_subtopic.inc }}" class="len"
value="{{ subtopic.name }}">
<br>
{% endfor %}
{% endfor %}
{% endfor %}
{% endfor %}
And its done. Now i am getting my expected output.
I have this code(which doesn't give me expected result)
#subject_content.html
{% block main-menu %}
{% include "subject_base.html" %}
{% endblock %}
#subject_base.html
....
....
<div id="homework" class="tab-section">
<h2>Homework</h2>
{% include "subject_file_upload.html" %}
</div>
child template:
#subject_file_upload.html
<form action="." method="post" enctype="multipart/form-data">{% csrf_token %}
{{ form.as_p }}
<input type="submit" value="submit">
</form>
and my view
#views.py
#login_required
def subject(request,username, subject):
if request.method == "POST":
form = CarsForm(request.POST, request.FILES)
if form.is_valid():
form.save()
return HttpResponseRedirect("/")
form = CarsForm()
return render_to_response('subject_content.html', {'form':form}, context_instance=RequestContext(request))
The above code creates HTML in the way I want it to be, however the form does not update database.
BUT,
If I skip the middle template and go directly to the uploading form, it works fine:
#subject_content.html
{% block main-menu %}
{% include "subject_file_upload.html" %}
{% endblock %}
Help me please to make it work with middle template.
I want to do this, because I don't wan't to type the same code more than once.
Like #Besnik suggested, it's pretty simple:
{% include "subject_file_upload.html" with form=form foo=bar %}
The documentation for include mentions this. It also mentions that you can use only to render the template with the given variables only, without inheriting any other variables.
Thank you #Besnik
