将Django表单值传递给html

Question

I am working on a Django project and I have a form with a username field. I am trying to pass the username (just the value not the whole field that is given by form.username) from the form using form.fields['username'] but I get the following error:

Could not parse the remainder: '['username']' from 'form.fields['username']'

my html is:

{{form.fields['username']}}

and my form is :

class RegisterationForm (forms.Form):

    first_name = forms.CharField(initial = 'eg. John',widget=forms.TextInput(attrs={'class' : 'form-control'}))
    last_name = forms.CharField(initial = 'eg. lennon',widget=forms.TextInput(attrs={'class' : 'form-control'}))
    username = forms.CharField(initial = 'eg. J.Lennon',widget=forms.TextInput(attrs={'class' : 'form-control'}))
    email = forms.EmailField(initial = 'form: example@something.com',widget=forms.TextInput(attrs={'class' : 'form-control'}))
    password = forms.CharField(initial = '******',widget=forms.TextInput(attrs={'class' : 'form-control'}))
    password2 = forms.CharField(initial = '******',widget=forms.TextInput(attrs={'class' : 'form-control'}))

My form is not bounded but since it has initial value I was expecting to see the initial value in the form.fields['username'] but I still get an error. I have passed the form from the view function btw. (when I just put {{form}} I do get the whole form on my HTML)

Answer 1

The correct way to do it is {{form.NAME_OF_THE_FIELD}} so for you it should be {{form.username}}

Edit:

Then to access username value it should be {{ form.username.value }}

Answer 2

As @ddalu5 mentioned the right command for the HTML is

{{from.username.value}}

It is funny how I could not find that anywhere.

Answer 3

{{form.fields['username']}} is invalid django template syntax. You should use {{ form.name_of_field }} instead.

Check django doc about render form fields manually .

You can't do dict lookup in django template using [] , there's only . lookup. Check django doc about the sequence of dot lookup in django template .
