hello,

I've tried to create a simple CharField in a Form and show it in my webbrowser
but I didn't see anything on my webbrowser?


Below my code:

forms.py
from django import forms



class  menuForm(forms.Form):
    image = forms.CharField(initial = 'Your Name')
    date = forms.DateField()
   

   


urls.py
from django.urls import path
from . import views

urlpatterns = [
    path('', views.menu),    

]

Views.py
from django.shortcuts import render
from django.http import HttpResponse
from .forms import menuForm

def menu(request):
    frm = menuForm()
   
    return  render(request, 'base.html',  {' form ': frm} )
   


html-file

<html lang="de">

<head>
    <title> Menu</title>
   
</head>
<body>
Hallo
    <p>{{ frm }}</p>
   
</body>
</html>

I can only see "Hallo" on my webbrowser but no input for a CharField?

Can anybody help?

instead of  <p>{{ frm }}</p>, try:

 <p>{{ form }}</p>

I think you'll understand what you did wrong.

You passed form to template, so you have to refer to that.

There's one more error in your code, and it's right here:

> return render(request, 'base.html', {' form ': frm} )

As you can see above, you're passing a context variable by the name of
“ form ” with a leading an trailing space to the template engine. As
far as I know, context variables cannot contain spaces, because there
is no way to actually refer to them from the template itself.
Honestly, I'm surprised that doesn't raise an error.

Regardless, you should remove the spaces around “form”, and then
you'll be able to refer to the form as, well, “form” in your template.

Good luck,

Michal

Hi Michal,

yes that was the error.
Thank you so much.
Strange that no error was shown.
