Is it possible to save the javascript html5 geolocation latitude and longitude to the django admin when user uses the geolocation website. The web page goal is to save the user's longitude and latitude values so that the data can be accessed later on when user signs in again.
I found a similar question being asked in stackoverflow years ago but there hasn't been any answer. The link is : Save JavaScript GeoLocation data to Django admin page
It would be great if there this an answer based on this code link.
Another option I read about is to create a html form and set the form to be autopopulated by jQuery from data produced by the javascript html5 geolocation. Again this is quite complicated for a beginner like me.
I would appreciate any bit of help whether by code, tutorial, blog post, examples or links. I don't expect all the programming code to be provided (although I do learn better from examples) but it would help if there are some material/example I could go to, to implement my programming tasks. Thank you.
I am currently up to here with my progress but still am unable to post the latitude and longitude to the django admin page:
code is as following:

It "POST"s the data but it does not appear in the django admin. I trawled many websites searching for answers why but still haven't found any. Thank you again for your help.
I have used jQuery and Ajax to submit the longitude and latitude data to any model you want to store these data in.
in your model.py:
from django.contrib.auth import User
class UserGeoLocation(models.Model):
user = models.OneToOneField(User)
latitude = models.FloatField(blank=False, null=False)
longitude = models.FloatField(blank=False, null=False)
for your view.py
def save_user_geolocation(request):
if request.method == 'POST':
latitude = request.POST['lat']
longitude = request.POST['long']
UserGeoLocation.create(
user = request.user
latitude= latitude,
longitude = longitude,
)
return HttpResponse('')
now that we have the view we can setup a url endpoint to submit the post request
url('^abc/xyz/$', appname.views.save_user_geolocation)
and Finally for the actual form,
$(document).on('submit', '#id', function(e){
e.preventDefault();
$.ajax(
type='POST',
url = 'abc/xyz',
data : {
lat:position.coords.latitude,
long: position.coords.longitude
csrfmiddlewaretoken:$('input[name=csrfmiddlewaretoken]').val()
},
});
for the last step, lets say you used the js code from the example you linked, then you can assign these coordinates value to variables that will be submitted with the post request that gets triggered when the user clicks on the button, the id here is the id of the form you want to submit the data from, and the e.PreventDefault is to stop the page from reloading when you post the data. Finally, the csrf token is required by django to able to submit the form.

I am referring to BugBytes channel on YouTube about sortable menu with Django.
(Django and HTMX #6 (part 1) - Building a Sortable Drag and Drop Interface
)
https://www.youtube.com/watch?v=V-f_yYKUJo8
(Django and HTMX #6 (part 2) - Building a Sortable Drag and Drop Interface
)
https://www.youtube.com/watch?v=5Fuwo4tVXmE
Some people got stuck by the same issue but found a clue getting through it.
I couldn't have any implication.
Same question found in StackOverflow here."Sortable JS breaks upon htmx rendering a partial"
And I don't think that Answer seems to show any solutions.
In my case, following the BugBytes tutorial video and the repository, I made the following Django files.

I've noticed while I was about to post this Question that what if I change the target file to render about sort() function in views.py file???
So I changed sort() function in views.py file like the next!!
def sort(request):
books_order_list = request.POST.getlist('book_order')
print(books_order_list)
all_books = []
for idx, book_pk in enumerate(books_order_list, start=1):
book = Books.objects.get(pk=book_pk)
book.order = idx
book.save()
all_books.append(book)
context = {
'all_books': all_books,
}
return render(request, 'books.html', context)
I change the target template file to render like "list_books.html" to "books.html".
And finally it completely works fine!!
In the tutorial video by BugBytes, the target template file of sort() function in views.py is "film-list.html" upon re-checking.
So now, it must be "films.html".
I hope this will be helpful for future students.
Because there are few resources for reference about HTMX and sortable class of that.
Happy coding!! :D!!
class DownloadForm(FlaskForm):
products = service.get_products()
choices = [(product, product.replace('-', ' '))
for product in products]
application = SelectField(
'Application',
[DataRequired()],
choices=choices
submit = SubmitField('Submit')
#home.route('/downloads/<application_name>', methods=['GET', 'POST'])
def downloads():
download_form = DownloadForm()
My route will be downloads/application_name.
Can I send this routevalue "application_name" to the form to filter out the choices in the Download Form?
I'm new to entire flask and python.
You can use a factory function to use the parameter from the URL to do your database query. Based on this query, a form is then created that can be used within the route.
def download_form_factory(name):
products = [
'Archiver',
'Editor-1',
'Editor-2',
'Music-Player',
'Video-Player'
]
class DownloadForm(FlaskForm):
app = SelectField(
'Application',
choices= [
(product, product.replace('-', ' ')) \
for product in filter(lambda p: name.lower() in p.lower(), products)
]
)
submit = SubmitField('Download')
return DownloadForm
The following example uses an input field of type QuerySelectField from WTForms-SQLAlchemy to facilitate database queries. As you can see above, the functionality is also possible with a normal SelectField.
A number of products are added to the database which, in addition to their name, have an additional property build.
If the user selects a name on the index page, all products that have the selected name are available for selection. He can then choose between the offered versions.
The form is created inside a function. The name to be searched for is passed to this function as a parameter. This can then be used to create the database query.
def download_form_factory(name):
# Create a class of the form.
class DownloadForm(FlaskForm):
# Create the select field
app = QuerySelectField(
# with a label
'Application',
# and the database entries containing the given name as options
query_factory=lambda: Product.query.filter(Product.name.ilike(f'%{name}%')).all(),
# and a label for each of these options.
get_label=lambda p: '%s (Build %s)' % (p.name, p.build),
# An option must be selected by the user.
validators=[InputRequired()]
)
# Create the Submit button.
submit = SubmitField('Download')
# Return the created form class.
return DownloadForm
Within the endpoint, the function mentioned is used and an instance of the form is created, which can be used in the usual way.
#app.route('/download/<string:name>', methods=['GET', 'POST'])
def download(name):
# Create the form and an instance of it.
form = download_form_factory(name)(request.form)
if form.validate_on_submit():
# If the POST request is sent with valid information,
# the form data can be requested.
# The result is the selected database object.
print(form.app.data)
return render_template('download.html', **locals())

I have a django project that I'm trying to add a custom "online" state to (boolean field in a model). I want to refresh a div periodically to show if a user is now online. The div which is refreshed, with the class button-refresh, is in an included HTML file.
The issue is that the include doesn't work with my for loop in the original HTML file, none of the "professionals" data is retrieved from the server. I'm pretty new to django, my assumption is that the refresh_professionals.html file is retrieved with the ajax request and is entirely separate from the all_professionals.html and then included, without ever being a part of the for loop meaning that the {{ professional.professional_profile.online }} syntax doesn't work.
Any ideas on how to fix this issue? If there is a better way to do this, let me know. Thanks.
all_professionals.html
{% for professional in professionals %}
...
{{ professional.name }}
{% include 'professionals/refresh_professionals.html' %}
...
{% endfor %}

{% block postloadjs %}

});

def refresh_professionals(request):
"""A view to refresh the online button section"""
professionals = Professional.objects.all()
context = {
'professionals': professionals,
}
return render(request, 'professionals/refresh_professionals.html', context)
EDIT
I've followed Daniel's advice and am now returning a JSON object. This is the updated code
professionals.js
$(document).ready(function(){
setInterval(function() {
$.ajax({
url: global_url,
type: 'GET',
success: update_professionals,
});
}, 5000)
});
function update_professionals(response){
// unpack the response (context) from our view function:
var professionals = response.professionals;
// update html:
var i;
for (i = 0; i < professionals.length; i++) {
$('#professional-name' + i).text('professionals.name' + i);
};
};
views.py
def refresh_professionals(request):
"""A view to refresh the professionals section page"""
professionals = Professional.objects.all()
professionals = serializers.serialize("json", professionals)
context = json.dumps({
'professionals': professionals,
})
return HttpResponse(context)
The issue I'm facing now is referencing the professionals data. It's returning uncaught errors. The forloop is necessary because in my HTML I've got a series of IDs with a number attached to the end using a django forloop.counter. Any advice would be appreciated. Thanks.
Okay, lets assume we have a view function like so:
from django.http import HttpResponse
import json
def refresh_professionals(request):
"""A view to refresh the online button section"""
professionals = Professional.objects.all()
# convert to json friendly format:
professionals = ...
context = json.dumps({
'professionals': professionals,
})
return HttpResponse(context)
This assumes professionals now looks something like (the actual structure will obviously be different):
professionals = {"id":1, "name":"Jason"}
Now, in our js file we should have an ajax request like so (wrapped in a setInterval method, etc.):
$.ajax({
url: global_url,
type: 'GET',
success: update_professionals, // reference to an ajax-success function
});
And our success function like so:
update_professionals(response) {
// unpack the response (context) from our view function:
// use JSON.parse() to convert a string to json
var professionals = JSON.parse(response.professionals);
// update html:
$('#professional-name').text(professionals.name)
}
This assumes we have an HTML element like so:
<div id="professionals-name"> Sue </div>
The difference is we are using js to update the HTML on the fly instead of trying to re-render an HTML template likely will require a page refresh.
I want to use the signature_pad from https://github.com/szimek/signature_pad to attach an image to a Django Form that gets saved to a server. With the code I have, I can successfully download the image from the signature pad as well as upload an image to the server with a link to the image on the database via Django’s ImageField. However, I can’t get the signature image sent to the server.
I think the two remaining things I need to be able to do are:
Send the image to the signature field form.
Encode the image so I can save it to a server.
I’ve got a couple other non-essential questions: is the image data currently saved in signaturePad.toDataURL until it’s submitted? I don’t know enough to have a preference as to whether the image is sent to the server as a Data URI string or a link to a .PNG file. I imagine a string is easier to deal with down the road, correct?
Here's my models.py
from django.db import models
class testModel(models.Model):
name = models.CharField(max_length=50)
image = models.ImageField(upload_to='signatures/')
signature = models.FileField()
forms.py:
from django import forms
from .models import testModel
class testForm(forms.ModelForm):
class Meta:
model = testModel
fields = '__all__'
widgets = {'signature': forms.HiddenInput()}
views.py:
from django.shortcuts import render
from django.urls import reverse
from django.http import HttpResponse, HttpResponseRedirect
from .Forms import testForm
from .Models import testModel
def testFormPage(request):
if request.method == 'POST':
form = testForm(request.POST, request.FILES)
if form.is_valid():
form.save()
return HttpResponseRedirect('/thanks/')
else:
form = testForm()
return render(request, 'testFormPage.html', {'form': form})
and the the HTML form:
<form action="{% url 'testFormPage' %}" method="post" enctype="multipart/form-data">
<div id="signature-pad" class="signature-pad">
<div class="signature-pad--body">
<canvas></canvas>
<button type="button" class="button save" data-action="save-png">Save as PNG</button>
</div>
</div>
<input type="hidden" name="signature" value="formSig.value" id="formSig">
<input type="submit" value="Submit">
</form>
Rather than copying the entire js app (https://github.com/szimek/signature_pad/tree/master/docs/js), here are the lines I added. I don't really know javascript so I've just tried to Frankenstein together what I've copied here and there.
var savePNGButton = wrapper.querySelector("[data-action=save-png]");
var formSig = wrapper.querySelector("[data-action=formSig]");
// and...
savePNGButton.addEventListener("click", function (event) {
if (signaturePad.isEmpty()) {
alert("Please provide a signature first.");
} else {
var dataURL = signaturePad.toDataURL();
download(dataURL, "signature.png");
}
});
formSig.addEventListener("submit", function(event) {
if (signaturePad.isEmpty()) {
alert("Please provide a signature first.");
} else {
signature.value = signaturePad.toDataURL();
};
I have an sqlite3 database setup with django 1.6 where I want web users to be able to enter text and see it in 3 live tables (high, low and latest) all on the same page. The one page ideally should have text entry, voting, display of the three tables updated when new entries go in or are voted on, and a search if possible if all that gets sorted (personal project, not commercial). I am also on win7 64 if that matters...
Currently I have: a working database the three tables displaying in a web page without update and some web text input via js (and failing to save to the database in Django).
I shied away from forms at first, as they seem to want separate html pages for input. Asking an experienced django coder, he helped me out with some javascript for text entry on the page. He said I didn't need to do it via forms and POST, GET, as the text was just going in with the initial score of 0 and the current datetime.
My issue now is that I cannot get the entered text to save into the database without error.
Since I need to program this in 2-3 weeks and am new to django (and oblivious to javascript, though I've done some Processing with PHP), my questions are;
Am I missing something obvious with the text input save to database?
-and-
Is there a way to have all this using forms and GET, POST in one page
so I can avoid a lot of javascript (unless it is truly easier)?
I am going to start to try to build this with Forms at the moment, but hope for a bit of guidance on best practice from wiser heads.

context = {
'latest_entry_list': Entry.objects.order_by('-pub_date')[:10],

#created_score = '0'
#created_text = 'test'
#e = Entry(text=created_text, score=created_score,pub_date=created_date)
#e.save()
return HttpResponse('done')
I am unsure of defining the fields for populating the Entry....does the above look right?
I can uncomment the e=Entry(etc...) without error,
but when I uncomment the e.save(), the error is:
GET http://127.0.0.1:8000/add/a 500 (INTERNAL SERVER ERROR) jquery.min.js:4
send jquery.min.js:4
n.extend.ajax jquery.min.js:4
n.(anonymous function) jquery.min.js:4
(anonymous function) post.js:15
n.event.dispatch jquery.min.js:3
r.handle
I will be getting on with trying to do this in forms, but wonder if there is some good advice as to if that is possible - I would ideally like to avoid js extras as I am very unfamiliar with it and it would be another level of unknowns at this point. Any input greatly appreciated...
Your mistake in view function add:
created_date = models.DateTimeField('date published', default=datetime.now)
It must be value assign:
created_date = datetime.now()
Not field definition.
In advance you could specify auto_now_add=True in your model: https://docs.djangoproject.com/en/dev/ref/models/fields/#datefield
In that case field will be filled automatically.
Additional:
It is error in urls.py
You should do some fixes:
urls.py:
url(r'^add/$', 'entries.views.add'),
post.js
$("#input").bind("keypress", function(e) {
//enter key pressed
if (e.keyCode == 13) {
var text = $("#input").val();
var args = {'text': text};
$.get("/add/", args).done(function(data) {
console.log("message: " + data);
});
}
});
views.py
def add(request):
created_date = default=datetime.now()
created_score = '0'
created_text = request.GET.get('text')
e = Entry(text=created_text, score=created_score,pub_date=created_date)
e.save()
return HttpResponse('done')
Update - Solution
The solution in addition to the changes below was to add 'from datetime import datetime' in views....
