django forms set field order

Question

I am trying to set the fieldorder of my form. but somehow it just stays in alphabetical order. Anyone has some suggestions? i tried class Meta: fields = ["field", "field"] and adding a keyOrder in the init

form:

class HangarFilterForm(forms.Form):

    FIELDS = [
        ("", ""),
        ("warp", "Warp"),
        ("cargo_space", "Cargo Space"),
        ("smuggle_bay", "Smuggle Bay"),
        ("dock", "Dock/Undock"),
        ("enter_warp", "Enter Warp"),
        ("fuel_bay", "Fuel Bay"),
        ("fuel_cost", "Fuel Cost"),
    ]

    PER_PAGE = [
        (10, ""),
        (5, "5 ships"),
        (10, "10 ships"),
        (25, "25 ships"),
        (50, "50 ships"),
    ]

    field_1 = forms.ChoiceField(choices=FIELDS, label="1st attribute", required=False)
    field_2 = forms.ChoiceField(choices=FIELDS, label="2nd attribute", required=False)
    per_page = forms.ChoiceField(choices=PER_PAGE, required=False)

    def __init__(self, *args, **kwargs):
        super(HangarFilterForm, self).__init__(*args, **kwargs)
        self.fields['planet'] = forms.ChoiceField(
                        choices=[("", "")] + [ (o.id, o.name) for o in    lanet.objects.all().order_by("name")], 
                        required=False)
        self.fields['type'] = forms.ChoiceField(
                        choices=[("", "")] + [ (o[0], o[1]) for o in ShipTemplate.SHIP_TYPES], required=False)
        self.fields.keyOrder = ["planet", "type", "field_1", "field_2", "per_page"]

In Django 1.9, new way of forcing the order of form's fields has been added : field_order.

Take a look (link to version 1.9): https://docs.djangoproject.com/en/1.9/ref/forms/api/#django.forms.Form.field_order

(and a link to dev version): https://docs.djangoproject.com/en/dev/ref/forms/api/#django.forms.Form.field_order

Find below a short example (using Django 1.9)

models.py:

from django.db import models

class Project(models.Model):
     end_date = models.DateField(verbose_name='End date',
                                blank=True)

    start_date = models.DateField(verbose_name='Start date',
                                  blank=True)

    title = models.CharField(max_length=255,
                             blank=False,
                             verbose_name='Title')

    def __str__(self):
        return self.title

forms.py

from django.forms import ModelForm, DateTimeField, SelectDateWidget

from XXX.models import Project

class ProjectForm(ModelForm):
    class Meta:
        model = Project
        fields = '__all__'

    start_date = DateTimeField(widget=SelectDateWidget)
    end_date = DateTimeField(widget=SelectDateWidget)

    field_order = ['start_date', 'end_date']

In this example the fields will be rearranged to:

1. start_date <== using the list in the form class
2. end_date <== using the list in the form class
3. title <== not mentioned in the list, thus using the default ordering

I tried setting fields in Meta part of form in django 2.1 and it also did the trick:

class MyForm(forms.ModelForm):
    ...

    class Meta:
        model = Contact
        fields = ('field_1', 'field_2', 'field_3', 'field_4',)
