Django 0 : Form Field Rendering Enhancements
Django 5.0 introduced field group and field group templates. These concepts enable developers to render different parts of a form field easily, like errors, help texts, labels, and widgets. Developers can access each form field “{{ form.name_of_field }}” in templates in Django forms. Each field comprises an “as_field_group()” function that renders the various parts of the form field. Therefore, the “as_field_group()” function helps developers create generic templates for organizing field elements in the preferred/required layout.
Django, by default, uses the “django/forms/field.html” template and the “django/forms/div.html” form style. However, developers can customize the “django/forms/field.html” template on a Customization options:
- Per-project basis: Developers can set “field_template_name” in the project-level “FORM_RENDERER” to customize the template for an entire project.
- Per-field basis: Developers can define the field in a form class with template_name=”your_custom_template.html”.
- Per-request basis: Developers can use the “BoundField.render()” method and specify a different template name to customize the template on a request basis.
Forms in django:
Python3
# Example Code for Form Types class MyForm(forms.Form): name = forms.CharField(label='Name', max_length=100) email = forms.EmailField(label='Email') file = forms.FileField(label='File') |
Creating Forms in Django :
Python3
from django import forms class ContactForm(forms.Form): name = forms.CharField(max_length=100) message = forms.CharField(widget=forms.Textarea) |
Customized Form Example :
Python3
from django.shortcuts import render def my_view(request): if request.method == 'POST': form = MyForm(request.POST) if form.is_valid(): # Process the form data name = form.cleaned_data['name'] email = form.cleaned_data['email'] age = form.cleaned_data['age'] # … Else: form = MyForm() return render(request, 'my_template.html', {'form': form}) |
Rendering Form Fields:
HTML
<form method="post"> {% csrf_token %} {% for field in form %} <div class="form-group"> {{ field.label_tag }} {{ field }} {% if field.help_text %} <small class="form-text text-muted">{{ field.help_text }}</small> {% endif %} {% for error in field.errors %} <div class="alert alert-danger">{{ error }}</div> {% endfor %} </div> {% endfor %} <button type="submit">Submit</button> </form> |
