How to use a function in another class and modify it Django

Question

Sup, need to use a function in a different class without losing the model, while still being able to change the function(not important, I can rewrite func into more flexible func). Can't solve this issue at least 10 hours. Google didnt help =( I know code is a little dirty, I will clean that :D

Don't worry

I have same header with form and another form in all pages.

Need form from class head in class stockpage. And everyone template and future classes as well.

Views

class head(View):
    template_name = "dental/mainpage.html"
    model = signup
    def get(self,request):
        if request.method == 'GET':
            form = UserSign
            return render(request, "dental/mainpage.html", {"form": form})
    def FormSign(self,request):
        if request.method == 'POST':
            form = UserSign
            if form.is_valid():
                body = {
                    'Name': form.cleaned_data['Name'],
                    'email': form.cleaned_data['email'],
                    'Number': form.cleaned_data['Number'],
                }
                info_user = "\n".join(body.values())
                send_mail(
                    'Sign',
                    info_user,
                    '[email protected]',
                    ['[email protected]'],
                    fail_silently=False) 
                return render(request, "dental/mainpage.html", {"form": form})   #self.template_name
            return render(request, "dental/mainpage.html", {"form": form})                     

class stockpage(ListView):
    template_name = "dental/stocks.html"
    model = stock
    context_object_name = "stocks"

@Som-1 code rewritten a million times. I know how to write correctly:D need form from class head in class stockpage. And everyone template and future classes as well. — Eric_Reinhart

You should just use a FormView, and you can use an {% include %}d fragment for the form on each page (or inherit it as a block from a super-template). — AKX

Try adding separate view for handling the form with hidden field for url to redirect to. Django's default auth views work like this. Also custom context processor may help to provide the form for all pages without overriding all their get or get_context_data methods.

Consider the example:

forms.py:

class MyForm(forms.Form):
    next_url = forms.CharField(widget=forms.HiddenInput, required=False)
    name = forms.CharField()
    password = forms.CharField(widget=forms.PasswordInput)

context_processors.py:

def my_form_context_processor(request):
    my_form = MyForm()
    my_form.fields['next_url'].initial = request.get_full_path()
    return {'my_form': my_form}

settings.py:

TEMPLATES = [
    {
        ...
        'OPTIONS': {
            'context_processors': [
                ...
                'my_app.context_processors.my_form_context_processor',
            ],
        },
    },
]

views.py:

class MyFormView(FormView):
    form_class = MyForm
    template_name = 'my_form.html'

    def form_valid(self, form):
        # ...
        next_url = form.cleaned_data.get('next_url')
        if not next_url:
            next_url = reverse('my_app:home')  # default
        return HttpResponseRedirect(next_url)


class ViewA(TemplateView):
    template_name = 'template_a.html'


class ViewB(TemplateView):
    template_name = 'template_b.html'

template_a.html:

{% include "my_form.html" %}

<h1>A</h1>

template_b.html:

{% include "my_form.html" %}

<h1>B</h1>

my_form.html:

<form action="{% url 'my_app:my_form' %}" method="POST">
    {% csrf_token %}
    {{ my_form.as_p }}
    <p><input type="submit" value="Go!"></p>
</form>

swears at "next" in context_processors.py and at url 'api:my_form' but there I don't know what I need to put. Help sansei! =)

Som-1 Over a year ago

what does it say for 'next'? As for 'api:my_form' you should reverse your url of the form view. E.g. in my urls it's like follows: path('my-form-view/', MyFormView.as_view(), name='my_form'), and the app name is api, then i reverse it as api:my_form.

Som-1 Over a year ago

also, next is a keyword in python. In case your editor swears on it, you may rename it to something like next_url or redirect_to, etc.

Eric_Reinhart Over a year ago

thx greatfully. I need to go, but I guess i will do that eventually.

Eric_Reinhart Over a year ago
