我想将views.py中的值传递给forms.py

Question

I want to pass values are gotten in views.py to forms.py. I wrote in views.py ,

def app(request):

    if request.method == "POST":
        form = InputForm(data=request.POST)
        if form.is_valid():
            name = form.cleaned_data['name']
            age = form.cleaned_data['age']

in forms.py

class InputForm(forms.Form):
    name = forms.CharField(max_length=100)
    age = forms.CharField(max_length=100)

def logic(self):
   #I want to use views.py’s name&age’s value here

I am new to Django, so how should I write codes to do my ideal thing?

Answer 1

actually you can access data in a form by cleaned_data property (that is a dict object), so as an example checkout save method here:

class CreatePostFrom(forms.Form):
    image = forms.ImageField(required=True)
    des = forms.CharField(required=False, max_length=250)
    location = forms.CharField(required=False, max_length=100)
    tags = forms.CharField(required=False, max_length=250)

    def save(self, user):
        tags = self.cleaned_data["tags"].split()
        for tag in tags:
            Tag.objects.get_or_create(name=tag)
        post = Post.objects.create(user=user,
                                   image=self.cleaned_data["image"],
                                   des=self.cleaned_data["des"],
                                   location=self.cleaned_data["location"])
        post.tags.add(*tags)
        return post

Answer 2

As I said in my comment:

Use variables in Form class.

class InputForm(forms.Form):
    name = forms.CharField(max_length=100)
    name_data = ""
    age = forms.CharField(max_length=100)
    age_date = 0

    def logic(self):
        # I want to use views.py’s name&age’s value here
        # You can play here with your age_data and name_data

And views.py:

def app(request):

if request.method == "POST":
    form = InputForm(data=request.POST)
    if form.is_valid():
        form.name_data = form.cleaned_data['name']
        age.name_data = form.cleaned_data['age']

EDIT ( I needed a coffee, sorry.. )

I have just seen that your cleaned_data come from your form so why not working in it directly like this in form Class:

class InputForm(forms.Form):
    name = forms.CharField(max_length=100)
    age = forms.CharField(max_length=100)

    def logic(self):
        # I want to use views.py’s name&age’s value here
        # Why don't you use cleaned_data['name'] and age from here?
        name = cleaned_data['name']

and simply keep your view like this.

def app(request):

if request.method == "POST":
    form = InputForm(data=request.POST)
    if form.is_valid():
        name = form.cleaned_data['name']
        age = form.cleaned_data['age']

Not sure this will work at 100% procent

but the goal of this answer is not to give you the exact solution but to let you experiment with your problem a bit. As a Python beginer you will learn more if you try by yourself and make a few reasearches.
