Editing an object with HTML form instead of Django model form

问题

I am trying to edit my objects using HTML form instead of Django model form. I need to know how to make the view for this (See my incomplete view below in bold)

Intro: I have a very simple html (invisible )form in the right column of my Index.html. when the user clicks on Locate me button. The form automatically fills the users latitude and longitude details and clicks submit(the user does not see the form). I use jQuery to achieve this

    <form method="post" action="#">
        {% csrf_token %}
        <input id="jsLat" type="text" placeholder="latittude" name="LAT">
        <input id="jsLon" type="text" placeholder="longitude" name="LON">
        <button type="submit" id="submit">Submit</button>
    </form>

My models are

class UserLocation(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    lat = models.FloatField(blank=True, null=True)
    lon = models.FloatField(blank=True, null=True)
    point = models.PointField(srid=4326, default='SRID=4326;POINT(0.0 0.0)')

My incomplete view(I need help completing this)

@login_required
def edit_location(request):
    if request.method == 'POST':
      form = ??????????? #don't know how to call the HTML form   
        user = request.user              
        lat = request.POST.get('LAT') #lat is a field in the model see above
        lon = request.POST.get('LON') #lon is a field in the model see above
        form.save(commit=False) #Not sure if I can use this with HTML form
        point = lat (some operation) lon 
        form.save()
     return redirect("home") 

Also in the HTML form action do I use the URL created for this view

回答1:

You don't need a form in your view if you're manually picking the values from request.POST. Just create or modify a model instance directly.

You can create a form class that corresponds to the one you're writing manually to the the validation etc. when receiving data (but without using it to display the form). You'll likely need to add {% csrf_token %} to your html form if you do this (or mark the view csrf exempt).

urls.py

...
(r'^/my/special/url/', views.edit_location),

views.py (manually pulling request.POST parameters, and updating a model):

@login_required
def edit_location(request):
    if request.method == 'POST':
        #location,created = UserLocation.objects.get_or_create(user=request.user)
        location = UserLocation.objects.get_or_create(user=request.user)[0]
        location.lat = request.POST.get('LAT') #lat is a field in the model see above
        location.lon = request.POST.get('LON') #lon is a field in the model see above
        location.point = lat (some operation) lon 
        location.save()
     return redirect("home") 

form:

<form method="post" action="/my/special/url/">
    <input id="jsLat" type="text" placeholder="latittude" name="LAT">
    <input id="jsLon" type="text" placeholder="longitude" name="LON">
    <button type="submit" id="submit">Submit</button>
</form>
