wtf-peewee
this project, based on the code found in wtforms.ext, provides a bridge
between peewee models and wtforms, mapping model fields to form fields.
example usage:
first, create a couple basic models and then use the model_form class factory to create a form for the Entry model:
from peewee import *
from wtfpeewee.orm import model_form
import wtforms
class PasswordField(TextField):
""" Custom-defined field example. """
def wtf_field(self, model, **kwargs):
return wtforms.PasswordField(**kwargs)
class Blog(Model):
name = CharField()
def __unicode__(self):
return self.name
class Entry(Model):
blog = ForeignKeyField(Blog)
title = CharField()
body = TextField()
protected = PasswordField()
def __unicode__(self):
return self.title
# create a form class for use with the Entry model
EntryForm = model_form(Entry)Example implementation for an "edit" view using Flask:
@app.route('/entries/<int:entry_id>/', methods=['GET', 'POST'])
def edit_entry(entry_id):
try:
entry = Entry.get(id=entry_id)
except Entry.DoesNotExist:
abort(404)
if request.method == 'POST':
form = EntryForm(request.form, obj=entry)
if form.validate():
form.populate_obj(entry)
entry.save()
flash('Your entry has been saved')
else:
form = EntryForm(obj=entry)
return render_template('blog/entry_edit.html', form=form, entry=entry)Example template for above view:
{% extends "layout.html" %}
{% block body %}
<h2>Edit {{ entry.title }}</h2>
<form method="post" action="">
{% for field in form %}
<p>{{ field.label }} {{ field }}</p>
{% endfor %}
<p><button type="submit">Submit</button></p>
</form>
{% endblock %}
