Make a model form field not required

[Brendan Edwards]

Hi,

I am having some issues with making my form/model fields not required. Currently this is the code that I have:

forms.py:

class startRound(forms.ModelForm):

player_2 = forms.CharField(widget=forms.TextInput(attrs={'disabled':'True', 'hidden':'True', 'id':'player_2'}))

player_3 = forms.CharField(widget=forms.TextInput(attrs={'disabled':'True', 'hidden':'True', 'id':'player_3'}))

player_4 = forms.CharField(widget=forms.TextInput(attrs={'disabled':'True', 'hidden':'True', 'id':'player_4'}))

class Meta:

model = parentRounds

models.py

class parentRounds(models.Model):

Name = models.CharField(max_length=200)

player_1 = models.CharField(max_length=25)

player_2 = models.CharField(max_length=25, null=True, blank=True)

player_3 = models.CharField(max_length=25, null=True, blank=True)

player_4 = models.CharField(max_length=25, null=True, blank=True)

started_on = models.DateTimeField(auto_now_add=True)

completed = models.BooleanField(default = False)

The template is just the generic {{ form.player_1 }} with some jquery to hide/show player 2,3,4 depending on the select box value for number of players. Before I started adding jquery code to the template, this worked fine.

Any ideas what could have happened?!

Thanks in advance!

Now you just redefine fields with required=True by default. You need update widgets in __init__.

class startRound(forms.ModelForm):

class Meta:

model = parentRounds

        def __init__(self, *args, **kwargs):

                forms.ModelForm.__init__(self, *args, **kwargs)

                self.fields['player_2'].widget = forms.TextInput(attrs={'disabled':'True', 'hidden':'True', 'id':'player_2'})
                self.fields['player_3'].widget = forms.TextInput(attrs={'disabled':'True', 'hidden':'True', 'id':'player_3'})
                self.fields['player_4'].widget = forms.TextInput(attrs={'disabled':'True', 'hidden':'True', 'id':'player_4'})

Works like a charm, but I don't completely understand why that is necessary. When I defined the text input as hidden and disabled, it overwrote the initial settings of that field? 

what exactly does this line do?
