Django templates {% block content %} can contain only two form fields? - django

The question is: Can we send in the form into the template with more than 2 fields(I'm sure it should be possible). Please, advice what might be the issue:
I've created the form with 3 fields:
class Email(forms.Form):
owner = forms.ChoiceField(choices=['Tyler', 'Aleks'])
title = forms.CharField(max_length=150, label='Name the stuff')
file = forms.FilePathField(path=path, label='Enter the path')
Afterward, operated it in view, where I'm sending form object to the template:
def mail_distribution(request):
if request.method == 'POST':
form = Email(request.POST)
if form.is_valid():
render(request, 'general/email.html', {'form': form})
else:
form = Email()
return render(request, 'general/email.html', {'form': form})
Here is the template itself:
{% extends 'general/base.html' %}
{% block content %}
<form class="form-vertical" action="mail_distrib" role="form" method="post">
{% csrf_token %}
<div class="form-group" style="display: inherit">
<center>
{{form.title}}
</center>
</div>
<div class="form-group" style="display: inherit">
<center>
{{form.owner}}
</center>
</div>
<div class="form-group" style="display: inherit">
<center>
{{form.file}}
</center>
</div>
<center><input type="submit" value="OK"></center>
</form>
{% endblock %}
Afterwards I get the error:
*Error during template rendering
In template E:\Tyler\Projects\Web_dev\dj_api\Scripts\distribution\general\templates\general\email.html, error at line 13
too many values to unpack (expected 2)
line13 - 13 {{form.owner}}*

Change choices attribute in owner fields like this
owner = forms.ChoiceField(choices=[('Tyler','Tyler'), ('Aleks', 'Aleks')])

How to save checkbox value in django?

I am using checkboxes in Html and everytime I refresh my page, the checkboxes are unchecked again. How do I prevent this from happening ? Do I have to use JS ?
I tought about booleans fields but I don't really know how to implement them ...
I looked at other threads and it talked about javascript, but I do not understand anything at all about it, nor how to implement it.
Here is my code :
views.py :
'
#login_required(login_url='/login')
def home(request):
check=False
MyToDo = Todo.objects.filter(user=request.user)
formtoDo = forms.TodoForm()
if request.method == 'POST' and 'todosub' in request.POST:
formtoDo = forms.TodoForm(request.POST)
if formtoDo.is_valid():
todoit = formtoDo.save(commit=False)
todoit.user = request.user
todoit.save()
return HttpResponseRedirect('/home?')
[...]
data ={'form': form, 'formtoDo': formtoDo, 'MyToDo': MyToDo, 'check':check}
return render(request, "capygenda/entries.html", data)
'
html :
<form method="POST", class="Entry">
{% csrf_token %}
<p>{{ formtoDo|crispy}} <button type="submit" name="todosub" >Add</button></p>
</form>
{% csrf_token %}
{% for toto in MyToDo %}
<form method="POST">
{% csrf_token %}
<ul class="list">
<li class="list-item">
<input type="checkbox" class="hidden-box" id="{{ toto.id }}" autocomplete="off"/>
<label for="{{ toto.id }}" class="check--label">
<span class="check--label-box"></span>
<span class="check--label-text">{{ toto }}</span>
</label>
<button class="button-24" role="button">Delete</button>
</ul>
</form>
Two steps:
In your views, if the form is submitted i.e., when request.method == 'POST' is True, pass another parameter {'checked: 'checked'}:
if request.method == 'POST' and 'todosub' in request.POST:
formtoDo = forms.TodoForm(request.POST)
if formtoDo.is_valid():
todoit = formtoDo.save(commit=False)
todoit.user = request.user
todoit.save()
return HttpResponseRedirect('/home?')
[...]
# ---- here look at the last item ----
data ={'form': form, 'formtoDo': formtoDo, 'MyToDo': MyToDo, 'check':check, 'checked':'checked'}
return render(request, "capygenda/entries.html", data
In your template, place that variable as an attribute in the input HTML element:
<input type="checkbox" class="hidden-box" id="{{ toto.id }}" autocomplete="off" {{ checked }}/>
This way, the checked attribute of the input will be dynamically placed. If it was passed via POST method, you have it. Otherwise, it's just empty.
add checked in the input field if you want it to keep it pre-checked or dependent on View values.
<input {% if checked %} checked{% endif %}"/>

How to render template after failed form validation?

urls.py:
urlpatterns = [
path('employee/add_employee/', views.add_employee, name='add-employee'),
path('employee/add_employee/add/', views.add_employee_action, name='add-employee-action'),
]
I have add-employee page and some forms to fill there.
views.py:
def add_employee(request):
personal_form = PersonalEmployeeForm()
history_form = EmployeeHistoryForm()
return render(
request,
'sections/add_employee.html',
context={
'personal_form': personal_form,
'history_form': history_form,
}
)
def add_employee_action(request):
if request.method == "POST":
personal_form = PersonalEmployeeForm(request.POST)
history_form = EmployeeHistoryForm(request.POST)
if personal_form.is_valid() and history_form.is_valid():
# here is some logic with models
return redirect('add-employee')
else:
personal_form = PersonalEmployeeForm()
history_form = EmployeeHistoryForm()
return render(
request,
'sections/add_employee.html',
context={
'personal_form': personal_form,
'history_form': history_form,
}
)
template:
<form id="a-submit-form" action="add/" method="POST">
{% csrf_token %}
<div class="column-wrapper">
<div class="column">
<div class="form-wrapper">
{% for field in personal_form.visible_fields %}
{% include "elements/forms/form_line.html" %}
<br>
{% endfor %}
</div>
</div>
<div class="column">
<div class="form-wrapper">
{% for field in history_form.visible_fields %}
{% include "elements/forms/form_line.html" %}
<br>
{% endfor %}
</div>
</div>
</div>
<div class="button-bar-wrapper">
<div class="button_bar">
<a class="a-button positive" id="submit">Добавить</a>
<a class="a-button" href="{% url 'employee' %}">Сотрудники</a>
<a class="a-button" href="{% url 'index' %}">На главуную</a>
</div>
</div>
</form>
Submitting by <a> element is tested and worked well with jQuery script.
The problem is after submitting invalid forms I have a page with blah-blah/employee/add_employee/add/ URL. And if I try to submit forms again I have a page with blah-blah/employee/add_employee/add/add/ URL, which is incorrect. How can I render the page with blah-blah/employee/add_employee/ URL and show all error messages?
This is likely because you have written a relative URL in the <form> tag of the sections/add_employee.html template. The template thus contains something like:
<form method="post" action="add/">
...
</form>
You can use a URL with the {% url … %} template tag [Django-doc]:
<form method="post" action="{% url 'add-employee-action' %}">
...
</form>
Furthermore one usually uses the same path to handle both the GET and the POST request. So in fact you might simply remove the 'add-employee' path.

Django: How to add comments under post

I have trouble adding comments under my posts on the website I'm creating using Django.
This is my story.html file, which is supposed to show the story title, the story itself, all the comments of the story and give users the ability to add a new comment. Although the form is shown, it is not usable. Even though I have added comments to the stories manually through admin, none of them is shown.
{% extends "pinkrubies/base.html" %}
{% block content %}
<div class="post-preview">
<h2 class="post-title"> {{ story.title }}</h2>
<p class="post-subtitle">
{{ story.story }}
</p>
</div>
<div class="post-preview">
{% for com in latest_comments %}
<div class="post-preview">
<p class="post-subtitle"> {{ comment.com }} </p>
</div>
{% endfor %}
</div>
{% if user_id %}
<div class="post-preview">
<form action="{% url 'pinkrubies:story' user.id story.id %}" method="post">
{% csrf_token %}
<div class="form-group">
<p class="post-title">
Comments
</p>
<textarea id="text" name="text"class="form-control" placeholder="Comment" rows="4">{{ comment.com }}
</textarea>
</div>
<button type="submit" class="btn btn-primary"> Submit </button>
</form>
</div>
{% else %}
<p class="post-meta">You must have an account to comment. Log in or Register</p>
{% endif %}
{% endblock %}
views.py
def story_view(request, user_id, story_id):
latest_comments = Comment.objects.order_by('-date')
if story_id is not None:
story = get_object_or_404(Story, pk=story_id)
else:
story = Story()
story.user_id = user_id
if request.method == 'POST':
story.title = request.post.get('title')
story.story = request.post.get('story')
story.date = timezone.now()
story.save()
return HttpResponseRedirect(reverse('pinkrubies:story', args=(user_id,)))
else:
context = {
'user_id': user_id,
'story_id': story_id,
'title': story.title,
'story': story,
'comments': story.comments,
'latest_comments': latest_comments
}
return render(request, 'pinkrubies/story.html', context)
def comment_view(request, comment, user_id):
latest_comments = Comment.objects.order_by('-date')
if request.method == 'POST':
comment.com = request.POST['com']

comment.save()
return HttpResponseRedirect(reverse('pinkrubies:story', args=(user_id,)))
else:
context = {'latest_comments': latest_comments}
return render(request, 'pinkrubies/story.html', context)
I am aware I have added the "latest_comments" in both views, I did that to see if any of it works and it doesn't. I'm not even sure that the comment_view is needed.
Also, when I try to submit a comment, this error is thrown:
AttributeError: 'WSGIRequest' object has no attribute 'post'
in story_view story.title = request.post.get('title')
Any help is welcome!
Thank you !!!
First of all, if you want to get something from POST, you should use request.POST.get('title'); although I would rather use a Form and let it handle the request.
At a first glance, this:
{% for com in latest_comments %}
<div class="post-preview">
<p class="post-subtitle"> {{ comment.com }} </p>
</div>
{% endfor %}
Sould be
{% for comment in latest_comments %}
<div class="post-preview">
<p class="post-subtitle"> {{ comment.com }} </p>
</div>
{% endfor %}
In your code, you're using com to iterate through latest_comments, yet you try to use comment to access com attribute (not sure how your Comment model looks like though)
It's accessed via request.POST. WSGIRequest object does not have a post field it has POST field.
Also, you are not sending the fields you are attempting to read from request.
...
story.title = request.POST.get('title')
story.story = request.POST.get('story')
...
only field you are sending is called text and it should be accessed like this
text = request.POST.get('text')
also template has more errors please check your code once again.

In django, how to use another model data from function based views

So I have a form that updates a key_instance object with a borrower. Currently my app needs the user to enter the name of the borrower, but I want it to display a dropdown list of data from another model the user model to select from, is there anyway to do this in a class based view? Here are my views.py and my template. What I was thinking is that I would like to use a get_list_or_404 on the user model and display it as a drop down list in the template and use that selection to populate the form field.
I manged to get the dropdown list to display in my template but I'm not sure as to how to save that value in my views.
Does anyone know if this is the right way or if this is doable? Thank you!!
views.py
def submit_key_request(request, pk):
"""
View function for renewing a specific keyInstance by admin
"""
key_inst=get_object_or_404(KeyInstance, pk=pk)
names = get_list_or_404(Users)
# If this is a POST request then process the Form data
if request.method == 'POST':
# Create a form instance and populate it with data from the request (binding):
form = UpdateKeyForm(request.POST)
# Check if the form is valid:
if form.is_valid():
# process the data in form.cleaned_data as required (here we just write it to the model due_back field)
key_inst.is_requested = True
key_inst.status = 'r'
key_inst.date_requested = datetime.date.today()
key_inst.borrower = form.cleaned_data['borrower']
key_inst.save()
# redirect to a new URL:
return HttpResponseRedirect(reverse('all-available-keys') )
# If this is a GET (or any other method) create the default form.
else:
form = UpdateKeyForm(initial={'borrower': 'N/A'})
return render(request, 'catalog/keyinstance_request_update.html', {'form': form, 'keyinst':key_inst})
template
{% extends "base_generic.html" %}
{% block content %}
<div class="wrapper">
<div class="centered"> <h1>Request Keys For Room: {{keyinst.roomkey}}</h1></div>
<div class="square-box">
<div class="square-content">
<form action="" method="post" >
{% csrf_token %}
<table style="display: inline-flex">
{{ form}}
</table>
<select name = 'name'>
{% for name in names %}
<option value="{{ name }}">{{ name }}</option>
{% endfor %}
</select>
<p>
(Please use their login name i.e. <b>{{ user.get_username }}</b>)
</p>
<p><input required id="checkBox" type="checkbox" onclick="validate()"> I accept the terms and conditions</p>
<p id="text" style="display:none">You Have Agreed To the Terms and Conditions</p>
<input type="submit" value="Submit" />
</form>
</div>
</div>
</div>
{% endblock %}
Here is how I manged to do it, Not sure if this is the best 'pythonic' or best practice. Please let me know if it's not.
my views.py
def submit_key_request(request, pk):
"""
View function for renewing a specific keyInstance by admin

name = request.POST['name']
key_inst.is_requested = True
key_inst.status = 'r'
key_inst.date_requested = datetime.date.today()
key_inst.borrower = name
key_inst.save()
return HttpResponseRedirect(reverse('all-available-keys') )
# If this is a GET (or any other method) create the default form.
else:
pass
return render(request, 'catalog/keyinstance_request_update.html', {'keyinst':key_inst, 'names':names})

Use two forms at the same time

I want to submit two forms in my template. The reason for that is, that I have two separate models, each with a model form, which I have to submit at the same time to create the desired result:
I have these two forms:
class BootstrapModelForm(ModelForm):
def __init__(self, *args, **kwargs):
super(BootstrapModelForm, self).__init__(*args, **kwargs)
for field in iter(self.fields):
self.fields[field].widget.attrs.update({
'class': 'form-control'
})
class DeckForm(ModelForm):
class Meta:
model = Deck
exclude = ('dust',)
class GuideForm(BootstrapModelForm):
class Meta:
model = Guide
exclude = ('author', 'upvotes', 'downvotes', 'release_date', 'modified', 'deck')
def __init__(self, *args, **kwargs):
super(GuideForm, self).__init__(*args, **kwargs)
self.fields['title'].label = 'Title of your AWESOME Guide!'
self.fields['public'].label = 'Check, when you want to make your guide public'
self.fields['public'].widget.attrs.update({
'class': 'checkbox'
})
self.fields['introduction'].label = 'Introduction (not required, but recommended)'
A deck is a part of the Guide that gets created. Since the user should be able to create his own deck while writing his guide, I need two forms.
In my views I handled it like this:
def guide_create(request):
if request.method == "POST":
deck_form = DeckForm(request.POST)
guide_form = GuideForm(request.POST)
if guide_form.is_valid() and deck_form.is_valid():
new_deck = deck_form.save(commit=False)
new_deck.dust = 0
new_deck.save()
new_guide = deck_form.save(commit=False)
new_guide.author = Account.objects.get(id=request.user.id)
new_guide.deck = Deck.objects.get(id=new_deck.id)
new_guide.save()
else:
print(guide_form.errors)
print(deck_form.errors)
else:
deck_form = DeckForm(prefix = 'DeckForm')
guide_form = GuideForm(prefix = 'GuideForm')
return render(request, 'hsguides/guide_create.html', {
'DeckForm': DeckForm,
'GuideForm': GuideForm,
})
I use commit=False so I still can insert the deck in my guide. Now my problem comes with creating the template. When I submit the forms with my current set up, I receive no errors any more but the guide and the deck aren't saved either!
<div style="width: 60%; margin: 0 auto;">
<form class="form-horizontal" method="POST" action="{% url 'GuideCreate' %}"> {% csrf_token %}
<fieldset>
{% for field in DeckForm %}
{% if field.errors %}
<div class="class-group error">
<label class="control-lable">{{ field.label }}</label>
<div class="controls">{{ field }}
<span class="help-inline">
{% for error in field.errors %}{{ error }}{% endfor %}
</span>
</div>
</div>
{% else %}
<div class="control-group">
<label class="control-label">{{ field.label }}</label>
<div class="controls">{{ field }}</div>
</div>
{% endif %}
{% endfor %}
</fieldset>
<fieldset>
{% for field in GuideForm %}
{% if field.errors %}
<div class="class-group error">
<label class="control-lable">{{ field.label }}</label>
<div class="controls">{{ field }}
<span class="help-inline">
{% for error in field.errors %}{{ error }}{% endfor %}
</span>
</div>
</div>
{% else %}
<div class="control-group">
<label class="control-label">{{ field.label }}</label>
<div class="controls">{{ field }}</div>
</div>
{% endif %}
{% endfor %}
</fieldset>
<div class="form-actions" style="margin-top: 4px;">
<button type="submit" class="btn btn-default">Submit</button>
</div>
</form>
</div>
Edit I don't receive an error message any more, the deck gets created as well but the guide that belongs to it not.
Just Change
return render_to_response('hsguides/guide_create.html', {
'DeckForm': DeckForm,
'GuideForm': GuideForm,
})
to
return render(request,'hsguides/guide_create.html', {
'DeckForm': DeckForm,
'GuideForm': GuideForm,
})
You're saying the guide doesn't get created. I see this line new_guide = deck_form.save(commit=False)..... shouldn't it be new_guide = guide_form.save(commit=False) ?
Not 100% but this might be a mistake. Hopefully, it's not just because you refactored the code for putting it here.
I didnot check the whole thing, but this place is wrong, it should be:
if request.method == "POST":
deck = DeckForm(request.POST)
if deck.is_valid():
# ....
you are not packing the POST data into your forms..
the same goes for the second form as well
Try this, you might forgot to pass the RequestContext:
from django.template import RequestContext
return render_to_response('hsguides/guide_create.html',
{'DeckForm': DeckForm, 'GuideForm': GuideForm},
RequestContext(request))
It passes the csrf token to the template.
