django Select or RadioSelect does not work.

[Poorna Thanneeru]

Hi,

Below is my code. If I use
  widget=forms.CheckboxSelectMultiple or SelectMultiple, it works for me.
But if I use Select or RadioSelect (I want only one to be selected): this doesn't work.

If I use 'Select', I get the list of versions  (e.g 5.6 and 5.7). If I select 5.7 and click on 'Upgrade', it returns with a message saying 'Enter the list of values'. Not sure what's wrong with 'Select'?

Thanks in advance.

                self.fields[instance_choice[0]] = forms.MultipleChoiceField(
                    label=_("Available Versions"),
                    required=False,
                    widget=forms.Select(
                        attrs={'class': 'switched',
                               'data-switch-on': 'instance',
                               dataKey: instance_choice[0]}))

                # Populate field with choices
                version_choices = []

                try:
                    # Retrieve the available datastore versions
                    ds_versions = trove_api.trove.datastore_version_list(request, instance.datastore['type'])
                except Exception as e:
                    logging.error("%s: Exception received trying to retrieve datastore versions for datastore %s. "
                                  "Exception is: %s",
                                  __method__, instance.datastore['type'], e)

                for avail_version in ds_versions:
                    version_choices.append((avail_version.name, avail_version.name))

                    self.fields[instance_choice[0]].choices = version_choices
