Question

我正在尝试在Django表单选择字段中设置一些默认值，在该字段中我向用户询问他的生日和他所居住的城市，我已经尝试过在表单中传递参数“ initial”并添加属性值，但是不起作用。

这是我的代码...

forms.py

class RegisterForm2(forms.Form):
    gender = forms.ChoiceField(choices = gender_choices,required=True)

    birthdate = forms.DateField(widget 
                =forms.SelectDateWidget(years=range(1900, 2020)))

    marital_status = forms.ChoiceField(choices = marital_status, 
                     required=True)

    districts = forms.ChoiceField(choices = districts, required=True)

    city = forms.CharField(widget = forms.TextInput(attrs= 
       {'id':'id_cidade', 'placeholder':'Nome da cidade onde vives'}))

    job = forms.CharField(widget = forms.TextInput(attrs= 
          {'id':'id_profissao', 'placeholder':'A tua Profissão'}))

    class meta:
        model = UserRegister
        fields = ['gender',
              'birthdate',
              'marital_status',
              'districts',
              'city',
              'job']

choices.py

gender_choices = (('F', 'Feminino'), ('M', 'Masculino'))

marital_status = (('S','Solteiro'), ('D', 'Divorciado'), ('V', 
                                       'Viuvo'), ('C', 'Casado'))

districts = (('Aveiro','Aveiro'), ('Beja','Beja'), ('Braga','Braga'), 
        ('Bragança','Bragança'), ('Castelo Branco','Castelo Branco'),
        ('Coimbra','Coimbra'), ('Évora', 'Évora'),('Faro','Faro'), 
('Guarda','Guarda'),('Ilha da Madeira','Ilha da Madeira'),('Ilha dos 
Açores','Ilha dos Açores'),('Leiria','Leiria'),('Lisboa','Lisboa'), 
         ('Portalegre','Portalegre'),('Porto','Porto'), 
('Santarém','Santarém'),('Setúbal','Setúbal'),('Viana do 
Castelo','Viana do Castelo'),
         ('Vila Real','Vila Real'),('Viseu','Viseu'))

Answer 1

默认情况下，ChoiceField的初始值是它的第一个元组，如果您和任何初始值都将该值作为快速元组传递。

gender_choices = (('initial', "choose"),('F', 'Feminino'), ('M', 'Masculino'))

Answer 2

你可以试试吗

MALE = 'M'
FEMALE = 'F'
gender_choices = (
           (MALE, 'Feminino'), 
           (FEMALE, 'Masculino'))

对于应该起作用的所有选择都这样做。
