I have a queryset which lists all users in an admin group. I am using this queryset for a dropdown field in a django template. This works but only lists actual users. But I want to add an additional option of 'all' to the dropdown. How to best do this? I can't append the queryset.
forms.py
indexer_name = forms.ModelChoiceField(
queryset=User.objects.filter(groups__name='indexers'),
initial='all',
required=True
)
template form:
<form action="{% url 'indexer_epg_search'%}" method="post">
{% csrf_token %}
<div class="row g-2 my-3">
<div class="col-md">
<div class="form-floating">
{{ form_indexer.indexer_name|add_class:"form-select"|attr:"placeholder:by Indexer" }}
<label for="id_indexer_name">by Indexer</label>
</div>
</div>

You need to add "enctype="multipart/form-data" to your form, so:
<form method="post" enctype="multipart/form-data">
See detailed explanation is this elaborate answer:
What does enctype='multipart/form-data' mean?
I have some field created by Django form and there are some other data I want to post to other form using jQuery(Ajax).
Is there any way to post them to different tables with two different ways at the same time?
form.py
class MyForm(forms.ModelForm):
class Meta:
model = models.Planning
fields = ['title','description','open','owner','upload_time']
template
<form id="myform" action="" method="POST" enctype="multipart/form-data">
{% csrf_token %}
{{ form.management_form }}
<div id="select_country">
<p style="display: inline;">country</p>
<select id="city">
<option selected disabled hidden>please choose</option>
{% for x in areas %}
<option value="{{x.area_country}}">{{x.area_country}}</option>
{% endfor %}
</select>
<select id="areas" name="my_areas"></select>
<br>
<div class="my_detail">
</div>
<br>
</div>
<div id="content_loi" class="col-lg-4">
<div class="col-lg-12" id="list"></div>
<div class="col-lg-12"">
<label>title:{{form.title}}</label>
<p><b>description:</b>{{form.description}}</p>
<button type="submit" class="btn btn-default" style="margin:0 auto;">submit</button>
</div>
</div>
</form>
I want to store the chosen areas and foreign key to another table with ajax
view
def make_list(request):
template = get_template('index.html')
areas = models.Area.objects.values('area_country').distinct()
max_my_id = models.RoutePlanning.objects.all().aggregate(Max('my_id'))
my_id = int(max_my_id['my_id__max']) + 1
#city = request.POST.get('my_areas')
if request.method == 'POST':
form = forms.MyForm(request.POST,initial={'owner':username,'route_id':my_id,'route_upload_time':datetime.now()})
if form.is_valid():
form.save()
return HttpResponseRedirect('/make_player')
else:
loi_form = forms.MyForm(initial={'owner':username,'route_id':my_id,'route_upload_time':datetime.now()})
request_context = RequestContext(request)
request_context.push(locals())
html = template.render(request_context)
return HttpResponse(html)
Trying to create a component under October CMS which create a ToDo list (Look at this video). Adding an item works fine but now I'm trying to set up and Ajax handler to delete one element when a button is clicked.
Thi is the html code:
<form>
<div class="panel panel-default">
<div class="panel-heading">
<h3 class="panel-title">Tasks assigned to: {{ __SELF__.name }}</h3>
</div>
<div class="panel-body">
<div class="input-group">
<input name="task" type="text" id="inputItem" class="form-control" value="" \>
<span class="input-group-btn">
<button type="submit" class="btn btn-primary"
data-request="{{ __SELF__ }}::onAddItem"
data-request-success="$('#inputItem').val('')"
data-request-update="'{{ __SELF__ }}::tasks': '#result'"
>Add</button>
</span>
</div>
<ul class="list-group" id="result">
{% partial __SELF__ ~ '::tasks' tasks=__SELF__.tasks removeId=__SELF__.removeId %}
</ul>
</div>
</div>
<form>
and the code of the component (named tasks) that render the list of tasks:
{% if tasks|length > 0 %}
{% for i in 0..tasks|length-1 %}
<li class="list-group-item">
{{ tasks[i] }}
<button class="close pull-right"
data request="{{ __SELF__ }}::onRemoveItem"
data-request-success="console.log(data)"
>
×
</button>
</li>
{% endfor %}
{% endif %}
Lastly the code of the handler (don't do so much):
public function onRemoveItem()
{
return [
'Name' => 'Federico';
];
}
Now, I set up the handler onRemoveItem putting its data-request in a button and, as explained on this page, clicking the button should start the handler's execution but this don't happen, while all works correctly in the Add button that insert the tasks in the database.
Can someone explain me what I'm doing wrong?

EDIT:
Solved, I had to link the framework js in the layout file
This question already has an answer here:
Django template/view issues with carousel
(1 answer)
Closed 7 years ago.
OK, so here's the deal:
This is currently what I'm working on:
See the two arrows at the top? That's where a carousel of pictures should be. However, there are no pictures in this carousel. That is, until I click the 'Upload' Button.
So, my goal is to make the pictures appear on the first page before I even click the 'upload' button.
How can I fix this problem? I'm kind of a noob at Django, and writing this code is like pulling teeth.
My code:
Index.html
{% extends 'webportal/defaults.html' %}
{% block body %}
{% include 'webportal/carousel.html' %}
<br/>
<div class="container">
<div class="row">
<div class="col-md-12">
<p> So far we have been able to establish what the user tables will be have created or are in process of
creating
the ability to create, update, destroy users.</p>
</div>
</div>
<div class="row">
<div class="col-md-12">
<p> For now this ability is limited to the main user table, however the models will be easily extended
to other
tables as they are needed</p>
</div>
</div>
<div class="row">
<div class="col-md-12">
<p> Also not a lot of thought has gone into styling yet, we know that the page is suppose to resemble
the parent
organizations page. Right now we have been more focused on getting each individual component
working. Later we
will merge them into a whole. </p>
</div>
</div>
</div>
{% include 'webportal/info_row.html' with one=one two=two three=three %}
{% endblock %}
Carousel.html:
{% load staticfiles %}
{% load filename %}
<div class="container">
<div class="row">
<div class="col-md-12">
<div id="myCarousel" class="carousel slide" data-ride="carousel">
<div class="carousel-inner" role="listbox">
{% for document in documents %}
<div class="item {% if forloop.first %} active {% endif %}">
<div class="row">
<div class="col">
<li>{{document.docfile.name}}</li>
<img src = "{{STATIC_URL}}img/{{document|filename}}" >
<p align="center"><form style="text-align:center" action="{% url 'webportal:delete' %}" method="post" enctype="multipart/form-data">
{% csrf_token %}
<p>{{ form.non_field_errors }}</p>
<p>{{ form.Document.label_tag }} {{ form.Document.help_text }}</p>
<p>
{{ form.Document.errors }}
{{ form.Document.docfile }}
</p>
<p><input type="submit" value="Delete" /></p>
</form></p>
</div>
</div>
</div>
{% endfor %}
</div>
<a class="left carousel-control" href="#myCarousel" role="button" data-slide="prev">
<span class="glyphicon glyphicon-chevron-left"></span>
<span class="sr-only">Previous</span>
</a>

<!-- /.carousel -->
</div>
</div>
<form action="{% url 'webportal:carousel' %}" method="post" enctype="multipart/form-data">
{% csrf_token %}
<p>{{ form.non_field_errors }}</p>
<p>{{ form.docfile.label_tag }} {{ form.docfile.help_text }}</p>
<p>
{{ form.docfile.errors }}
{{ form.docfile }}
</p>
<p><input type="submit" value="Upload" /></p>
</form>

)
If there is a way to do this, does it involve ajax? I asked this again because of a lack of an adequate answer.
You should pass the documents context variable to the template in the view which handles the /alzheimers/ page.
UPDATE: The view you should change is the views.boostrap(). So rendering of the template will be something like this:
def bootstrap(request):
...
return render_to_response('webportal/bootstrap.html',
{'documents': Document.objects.all()},
context_instance=RequestContext(request)
)
