Hi,

I have rendered a `model.form` multi select checkbox, but when POSTing the data, the checkbox value is not being passed in the request. The other fields are past and added to the database.

```auto
def add_project_view(request):
    form = ProjectForm
    next = request.POST.get('next', '/')
    if request.method == 'POST':
        form = ProjectForm(request.POST)
        if form.is_valid():
            form.save()
            return redirect('/')
        
    else:
        form = ProjectForm()
    return render(request, 'add_project.html', {'form':form})

```

```auto
<div class="parsley-checkbox wd-250 mg-b-0" id="cbWrapper2">												
    {% for checkbox in form.platform %}
        <label class="ckbox"><input data-parsley-class-handler="#cbWrapper2" data-parsley-errors-container="#cbErrorContainer2" data-parsley-mincheck="2" name="{{ checkbox.name }}" type="checkbox" value="{{ checkbox.id }}"><span>{{checkbox}}</span></label> 
    {% endfor %}											
</div>

```

Payload:

```auto
csrfmiddlewaretoken: Kf7y5IyS31oSjOJkR9HqztlE3eorPrv8b1yzEJ5QVfiFkE4WpsDLaIr1Uu3mvamS
name: GroupName2
website: https://test.com
twitter_handle: tom

```

```auto
platforms = [
    ('windows', 'windows'),
    ('linux', 'linux'),
    ('iOS', 'iOS'),
]
class ProjectForm(ModelForm):
    class Meta:
        model = Project
        fields = ('name','website','platform','twitter_handle')

        widgets = {
            'name': forms.TextInput(attrs={'class': 'form-control wd-xl-250'}),
            'website': forms.URLInput(attrs={'class': 'form-control wd-xl-250'}),
            'platform': forms.CheckboxSelectMultiple(attrs={'class':'ckbox'}),
            'twitter_handle': forms.TextInput(attrs={'class': 'form-control wd-xl-250'}),
      
        }

```

So it doesn’t seem to pass in the platform field?

Thanks

I don’t think we’re seeing enough of the template. Seeing the model would help, too.

Sorry Ken, forgot to paste my model.

```auto
class Project(models.Model):
    platforms = [
    ('windows', 'windows'),
    ('linux', 'linux'),
    ('iOS', 'iOS'),
]
    name = models.CharField(max_length=50, blank=False, unique=True)
    website = models.URLField(max_length=50, blank=False)
    platform = models.CharField(max_length=200, blank=True,choices=platforms)
    twitter_handle = models.CharField(max_length=50, blank=False, null=True)

    def __str__ (self):
        return str(self.name)

```

Below is the form

```auto
<form action="#" class="parsley-style-1" id="selectForm2" name="selectForm2" method="POST">
    {% csrf_token %}
    {{ form.non_field_errors }}
    <div class="">
        <div class="d-md-flex mg-b-20">
            <div class="parsley-input" id="fnWrapper">
                <label>Project Name: <span class="tx-danger">*</span></label>
                {{ form.name }}
            </div>
            <div class="parsley-input mg-md-l-20 mg-t-20 mg-md-t-0" id="lnWrapper">
                <label>Project Website: <span class="tx-danger">*</span></label>
                {{ form.website }}
            </div>
            <div class="parsley-input mg-md-l-20 mg-t-20 mg-md-t-0" id="lnWrapper">
                <label>Project Twitter Handle: <span class="tx-danger">*</span></label>
                {{ form.twitter_handle }}
            </div>
        </div>
    </div>											
        <div class="parsley-checkbox wd-250 mg-b-0" id="cbWrapper2">												
            {% for checkbox in form.platform %}
                <label class="ckbox"><input data-parsley-class-handler="#cbWrapper2" data-parsley-errors-container="#cbErrorContainer2" data-parsley-mincheck="2" name="{{ checkbox.name }}" type="checkbox" value="{{ checkbox.id }}"><span>{{checkbox}}</span></label> 
            {% endfor %}											
        </div>										
    </div>
</form>

Your platform field in the model is a CharField. It doesn’t make sense to render that in the form as a multi-select checkbox - only one platform can be selected in that case. I’m guessing there’s some interaction between the two causing this to not work.

That would make sense, but how do I record the selection of the checkbox if it’s not a CharField? How else does a multi-selection checkbox work?

A multi-selection checkbox would be used with (perhaps) something like a ForeignKey related table, or (with some work) a JSONField or a PostgreSQL ArrayField.

Otherwise, if you’re just looking to allow for the selection of one option from a list of choices, then you can use a [CheckBox widget](https://docs.djangoproject.com/en/4.0/ref/forms/widgets/#checkboxinput) for that field. (Or, perhaps more appropriately, radio buttons.)
