# 🛠️ Day 6: Django Forms – Beginner’s Web Dev Series

Yesterday, we learned how to create models and display them using views and templates. Today, you’ll learn how to let users **input data** into your project — using Django Forms.

Forms may look like regular HTML input fields on the surface, but Django gives you a powerful Pythonic way to **define, validate, and manage** them.

## 📍What You’ll Learn

* What Django Forms are and why they matter
    
* `forms.Form` vs `forms.ModelForm`
    
* Handling form submission and validation
    
* Rendering forms in templates
    
* Using CSRF tokens and protecting your data
    
* Building your first dynamic form

## What Are Forms in Django?

> A form is Django’s way of collecting input from users — cleanly and safely.

You can create a form in two ways:

* `forms.Form` – When you want to define each field manually
    
* `forms.ModelForm` – When you want to generate the form directly from a model
    

---

## Create a Basic Form – `forms.Form`

```python
# forms.py
from django import forms

class ContactForm(forms.Form):
    name = forms.CharField(max_length=100)
    email = forms.EmailField()
    message = forms.CharField(widget=forms.Textarea)
```

---

## Handle the Form in Views

```python
# views.py
from django.shortcuts import render
from .forms import ContactForm

def contact_view(request):
    form = ContactForm(request.POST or None)
    if form.is_valid():
        # process form.cleaned_data
        print(form.cleaned_data)
        return render(request, 'thank_you.html')
    return render(request, 'contact.html', {'form': form})
```

---

## Use the Form in a Template

```html
<!-- templates/contact.html -->
<h1>Contact Us</h1>
<form method="POST">
  {% csrf_token %}
  {{ form.as_p }}
  <button type="submit">Send</button>
</form>
```

---

## CSRF Token – Your First Security Layer

Django protects every POST form using a CSRF token. Just include `{% csrf_token %}` in your form.

> Without it, Django will block the request with a 403 error.

---

## Using `ModelForm` – Quicker Way with Models

```python
# models.py
class Feedback(models.Model):
    name = models.CharField(max_length=100)
    feedback = models.TextField()
```

```python
# forms.py
from django import forms
from .models import Feedback

class FeedbackForm(forms.ModelForm):
    class Meta:
        model = Feedback
        fields = ['name', 'feedback']
```

```python
# views.py
def feedback_view(request):
    form = FeedbackForm(request.POST or None)
    if form.is_valid():
        form.save()
        return render(request, 'thank_you.html')
    return render(request, 'feedback.html', {'form': form})
```

---

## 🎨 Styling Forms with Widgets

```python
class StyledForm(forms.Form):
    name = forms.CharField(widget=forms.TextInput(attrs={
        'class': 'form-control',
        'placeholder': 'Your name'
    }))
```

---

## ✅ Task for Day 6

Create a Contact Form with:

* Name, email, and message fields
    
* Submit button
    
* A thank-you page after submission
    
* Add a new model called `Feedback`
    
* Use `ModelForm` to save it
    
* Show success message using `messages.success`
    

---

## 🚀 What’s Next?

Tomorrow, on **Day 7**, we will:

* Django default authentication
    
* Protected views
