Tips for Maintaining White Space and Line Breaks in Django

Currently, I am working on a project where I aim to showcase a user's code. My approach involves utilizing Django's forms. However, upon submitting the form, the whitespace and line breaks do not seem to be preserved in the output.

I would greatly appreciate any assistance you can provide!

# Here is an example of my form

class VigenereCipherDiscussForm(forms.ModelForm):
    class Meta:
        model = VigenereCipherDiscuss
        fields = ['text', 'share']

        widgets = {
            "text": forms.Textarea(attrs={"class":"form-control", "rows":4}),
            "share": forms.Textarea(attrs={"class":"form-control", "rows":5, "placeholder": "Enter your cipher text or code here to share with others"})
        }

# (stackoverflow retains the line breaks, nicely indents the "class Meta")

If I input this code:

x = 2
if x == 2:
    return "2"
else:
    return None

# I wish for this code to be displayed in the exact format as it is right now!

Despite this, when using Django, the outcome I receive is:

x=2 if x==2: return "2" else return None

Answer №1

Utilize the linebreaks function

Revise your script to:

x=2\nif x==2:\nreturn "2"\nelse:\nreturn None

and in the template:

{{ value|linebreaks }}

Answer №2

If you want to allow users to input code using TinyMCE, it will be converted and saved in HTML format. To display this code on your webpage, add the following line of code in your .html file: {{ value|linebreaks|safe }}. You can see how TinyMCE looks like in this image: https://i.sstatic.net/ibffE.png
