[PYTHON] Todo App mit Django-Bootstrap-Modal-Forms-Plugin

Überblick

Ich habe eine Beispiel-App mit dem Modal-Formular von Bootstrap mit CreateView und UpdateView von Django erstellt. Ich verwende "BSModalCreateView" und "BSModalUpdateView", die Plug-Ins mit dem Namen "django-bootstrap-modal-forms" sind. Ich konnte keine japanische Referenz oder eine kleine Beispiel-App finden und habe sie zusammengefasst.

Umgebung

Python 3.8.0 Django 3.0.4 Bootstrap 4.1.3 Plugin: django-bootstrap-modal-forms

Installation

1. Installieren Sie das Plugin django-bootstrap-modal-forms

pip install django-bootstrap-modal-forms

2. Installieren Sie django-widget-tweaks

pip install django-widget-tweaks

Weise

Bearbeiten Sie settings.py

# myproject/myproject/settings.py  
INSTALLED_APPS = [
    ~
    'bootstrap_modal_forms',
    'widget_tweaks'
]

Modell zu verwenden

# mypeoject/myapp/models.py
import datetime
from django.db import models


class TodoItem(models.Model):
    item = models.CharField(max_length=50)
    item_date = models.DateField(default=datetime.date.today)
    user = models.ForeignKey(
        'auth.User',
        on_delete=models.CASCADE
    )

    def __str__(self):
        return self.item

Forms.py bearbeiten

# mypeoject/myapp/forms.py
from bootstrap_modal_forms.forms import BSModalForm
from modalform.models import TodoItem


class CreateUpdateTodoItemForm(BSModalForm):
    class Meta:
        model = TodoItem
        fields = ['item', 'item_date']

Views.py bearbeiten

# mypeoject/myapp/views.py
from bootstrap_modal_forms.generic import BSModalCreateView, BSModalUpdateView
from modalform.forms import CreateUpdateTodoItemForm
from modalform.models import TodoItem


def show_todo_items(request):
    all_items = TodoItem.objects.filter(user=request.user)
    return render(request, 'show_todo_items.html', {'all_items': all_items})


class CreateTodoItemFormView(BSModalCreateView):
    template_name = 'create_modal_form.html'
    form_class = CreateUpdateTodoItemForm
    success_message = 'Success: Item was created.'
    success_url = reverse_lazy('show_todo_items')

    def form_valid(self, form):
        form.instance.user_id = self.request.user.id
        return super(CreateTodoItemFormView, self).form_valid(form)


class UpdateTodoItemFormView(BSModalUpdateView):
    model = TodoItem
    template_name = 'update_modal_form.html'
    form_class = CreateUpdateTodoItemForm
    success_message = 'Success: Item was updated.'
    success_url = reverse_lazy('show_todo_items')


def delete_todo_item(request, todo_id):
    item = TodoItem.objects.get(pk=todo_id)
    item.delete()
    messages.success(request, ('Deleted successfully!'))
    return redirect('show_todo_items')

Bearbeiten von urls.py

from django.urls import path
from modalform import views

urlpatterns = [
    path('', views.show_todo_items, name='show_todo_items'),
    path('create_todo_item/', views.CreateTodoItemFormView.as_view(), name='create_todo_item'),
    path('update_todo_item/<int:pk>', views.UpdateTodoItemFormView.as_view(), name='update_todo_item'),
    path('delete_todo_item/<todo_id>', views.delete_todo_item, name='delete_todo_item'),
]

Vorlage erstellen (html)

Show_todo_items.html erstellen

{% extends 'base.html' %}
{% load static %}
~
{% block content %}
    <!--Todo zusätzliches Formular-->
    <form class="form-inline my-2 my-lg-0" method="POST" enctype="multipart/form-data">

                            <button type="button" class="bg-light rounded"><a href="{% url 'delete_todo_item' i.id %}"><span class="fa fa-pencil">×</span></a></button>
                        </td>

            {% endfor %}
            </tbody>
        </table>

    });

{% endblock content %}

Create_modal_form.html

{% load widget_tweaks %}

<form method="post" action="" autocomplete="off">
  {% csrf_token %}
  <div class="modal-header">
    <h3 class="modal-title">Create Item</h3>
    <button type="button" class="close" data-dismiss="modal" aria-label="Close">
      <span aria-hidden="true">&times;</span>
    </button>
  </div>

  <div class="modal-body">
    <div class="{% if form.non_field_errors %}invalid{% endif %} mb-2">
      {% for error in form.non_field_errors %}
        {{ error }}
      {% endfor %}
    </div>

    {% for field in form %}
      <div class="form-group">
        <label for="{{ field.id_for_label }}">{{ field.label }}</label>
        {% render_field field class="form-control" placeholder=field.label %}
        <div class="{% if field.errors %} invalid{% endif %}">
          {% for error in field.errors %}
            <p class="help-block">{{ error }}</p>
          {% endfor %}
        </div>
      </div>
    {% endfor %}
  </div>

  <div class="modal-footer">
    <button type="button" class="btn btn-outline-secondary my-2 my-sm-0" data-dismiss="modal">Close</button>
    <button id="create" class="btn btn-outline-secondary my-2 my-sm-0" type="submit">Save</button>
  </div>

</form>

<script type="text/javascript">
    $('#id_item_date').datepicker({
        dateFormat: 'yy-mm-dd',
        autocomplete: "off"
    })
</script>

• In diesem Beispiel wird die Datumsauswahl verwendet, um das Datum anzuzeigen. Die Formular-ID wird automatisch durch "id_field name" zugewiesen.

Update_modal_form.html erstellen

{% load widget_tweaks %}

<form method="post" action="" autocomplete="off">
  {% csrf_token %}
  <div class="modal-header">
    <h3 class="modal-title">Update Item</h3>
    <button type="button" class="close" data-dismiss="modal" aria-label="Close">
      <span aria-hidden="true">&times;</span>
    </button>
  </div>

  <div class="modal-body">
    <div class="{% if form.non_field_errors %}invalid{% endif %} mb-2">
      {% for error in form.non_field_errors %}
        {{ error }}
      {% endfor %}
    </div>

    {% for field in form %}
      <div class="form-group">
        <label for="{{ field.id_for_label }}">{{ field.label }}</label>
        {% render_field field class="form-control" placeholder=field.label %}
        <div class="{% if field.errors %} invalid{% endif %}">
          {% for error in field.errors %}
            <p class="help-block">{{ error }}</p>
          {% endfor %}
        </div>
      </div>
    {% endfor %}
  </div>

  <div class="modal-footer">
    <button type="button" class="btn btn-outline-secondary my-2 my-sm-0" data-dismiss="modal">Close</button>
    <button id="update" class="btn btn-outline-secondary my-2 my-sm-0" type="submit">Update</button>
  </div>

</form>

<script type="text/javascript">
    $('#id_item_date').datepicker({
        dateFormat: 'yy-mm-dd',
        autocomplete: "off"
    })
</script>

• Es ist fast dasselbe wie create_modal_form.html. Ich habe gerade den Modaltitel in Element erstellen → Element aktualisieren und die Schaltfläche zum Aktualisieren → Speichern geändert. Github Der Code der Beispiel-App wird auf Github hochgeladen. Ein Demo-Video wird auch in der Readme-Datei veröffentlicht, sodass es leichter zu verstehen ist, wenn Sie die folgende Seite sehen.

Zusammenfassung

Ich habe vorgestellt, wie ein modales CreateView- und UpdateView-Formular für Bootstrap4 mithilfe des Plug-Ins django-bootstrap-modal-forms erstellt wird.

Ich konnte in Django kein Beispiel mit modaler Form finden, daher hoffe ich, dass Sie darauf verweisen können.
