4. Clone or download application to your django project directory::

   wget https://github.com/djk2/django-popup-view-field/archive/master.zip -O /tmp/master.zip unzip /tmp/master.zip -d /tmp/ cd my_project_dir cp -r /tmp/django-popup-view-field-master/django_popup_view_field/ ./

Add django_popup_view_field to your INSTALLED_APPS setting ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

settings.py ::

INSTALLED_APPS = [
    ...
    'bootstrap3',    # If you use django-bootstrap3
    'crispy_forms',  # If you user django-crispy-forms

    'django_popup_view_field',
    ...
]

# If you want use bootstrap4 then uncomment
# DJANGO_POPUP_VIEW_FIELD_TEMPLATE_PACK = 'bootstrap4'

Warning: Is recommended use django-bootstrap3/django-bootstrap4 or django-crispy-forms to render forms and fields, but this is not necessary. You can still write django templates using pure CSS from bootstrap3/4. More information about bootstrap forms in here: http://getbootstrap.com/css/#forms

Add the django_popup_view_field urls to your root url patterns ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ urls.py ::

urlpatterns = [
    ...
    url(
        r'^django_popup_view_field/',
        include('django_popup_view_field.urls', namespace="django_popup_view_field")
    ),
]

Note: The URL path can be whatever you want, but you must include 'django_popup_view_field.urls' with the 'django_popup_view_field' namespace. You may leave out the namespace in Django >= 1.9

In your base template, add django_popup_view_field_javascript tag ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ django_popup_view_field_javascript template tag load all required javascripts and template-scripts for application. Tag should be append before body close tag and after jQuery and Bootstrap scripts.

base.html ::

<!DOCTYPE html>
{% load django_popup_view_field_tags %}

<html>
    <head>
        ...
        <!-- Bootstrap CSS should be here -->
        ...
    </head>

    <body>
        ...
        ...
        <!-- jQuery script should be here -->
        <!-- Bootstrap javascripts should be here -->
        ...
        ...
        {% django_popup_view_field_javascript %}
    </body>
</html>

Settings

DJANGO_POPUP_VIEW_FIELD_TEMPLATE_PACK ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Since version 0.6.0, django-popup-view-fields has built-in support for bootstrap4 also. To enable support for bootstrap4 you have to set DJANGO_POPUP_VIEW_FIELD_TEMPLATE_PACK to "bootstrap4" value.

• bootstrap3 - this setting will be load javascript and html templates for bootstrap3. This is a default value

• bootstrap4 - this setting will be load javascript and html templates for bootstrap4.

Value of DJANGO_POPUP_VIEW_FIELD_TEMPLATE_PACK is changing behavior of '{% django_popup_view_field_javascript %}' tag and PopupViewWidget class. Template scripts_include.html is using this flag to decide which template and javascript will be load. PopupViewWidget class is using this flag to decide which template for field should be load.

Simple Example

.. image:: https://raw.githubusercontent.com/djk2/django-popup-view-field/master/doc/static/simple_example.png :alt: Simple Example - screenshot

Create PopupView ^^^^^^^^^^^^^^^^^

Html content rendered by this view will be loaded into bootstrap dialog. Create your popup view same as normal django view.

| Your popup view must be subclass of django.views.generic.View

templates/myapp/popups/colors.html ::

<ul>
    <li data-popup-view-value="red" style="background:red;"> red hat </li>
    <li data-popup-view-value="blue" style="background:blue;"> blue sky </li>
    <li data-popup-view-value="green" style="background:green;"> green planet </li>
    <li data-popup-view-value="pink" style="background:pink;"> pink car </li>
</ul>

If user click on the element with the attribute data-popup-view-value, the value of this attribute will be set in form field and dialog will close.

|

If you want set content of element as value in form field, use html() for attribute::

<li data-popup-view-value="html()"> This text will be use :) </li>

popups.py ::

from django.views.generic import TemplateView
from django_popup_view_field.registry import registry_popup_view

class ColorsPopupView(TemplateView):
    template_name = 'myapp/popups/colors.html'

# REGISTER IS IMPORTANT
registry_popup_view.register(ColorsPopupView)

Remember that you must register your popup view. After register you can run your popup view by call url::

..../django_popup_view_field/ColorsPopupView

In template you can get url to popup view using url tag::

{% url "django_popup_view_field:get_popup_view" 'ColorsPopupView' %}

After register you can unregister your popup view::

registry_popup_view.unregister(ColorsPopupView)

# or unregister by view name

registry_popup_view.unregister_by_name('ColorsPopupView')

You can also get popup view class by name::

view_class = registry_popup_view.get('ColorsPopupView')
view_class.as_view()

Create Form with PopupViewField ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ forms.py ::

from django import forms
from django_popup_view_field.fields import PopupViewField
from myapp.popups import ColorsPopupView

class ColorForm(forms.Form):

    color = PopupViewField(
        view_class=ColorsPopupView,
        popup_dialog_title='What is your favorite color',
        attrs={'readonly': True},
        required=True,
        help_text='be honest'
    )

**class PopupViewField(view_class, popup_dialog_title, *args, kwargs)

• view_class - required - popup view class, view to render dialog content, must be subclass of django.views.generic.View
• popup_dialog_title - not required - Title for dialog, default Popup Dialog: Select value
• attrs - not required - provides attributes for Widget
• args and kwargs are default for CharField

Create typical FormView ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ views.py ::

from django.views.generic import FormView
from myapp.forms import ColorForm
from django.http import HttpResponse

class ColorFormView(FormView):
    template_name = "myapp/color_form.html"
    form_class = ColorForm

    def form_valid(self, form):
        color = form.cleaned_data.get("color")
        return HttpResponse("Your color: {0}".format(color))

Template using django-crispy-forms

templates/myapp/color_form.html ::

{% extends "base.html" %}
{% load crispy_forms_tags %}
{% crispy form %}

Template using django-bootstrap3

templates/myapp/color_form.html ::

{% extends "base.html" %}
{% load bootstrap3 %}

<form action="." method="post" class="form">
    {% csrf_token %}
    {% bootstrap_form form %}
    {% buttons %}
        <button type="submit" class="btn btn-primary">Submit</button>
    {% endbuttons %}
</form>

Template with pure bootstrap3 css (without django-bootstrap3 and crispy)

templates/myapp/color_form.html ::

{% extends "base.html" %}
<form action="." method="post" class="form">
    <div class="form-group">
        <label class="control-label"> {{ form.color.label }} </label>
        {{ form.color }}
    </div>
    <button type="submit" class="btn btn-primary">Submit</button>
</form>

callback_data attribute

If you want pass extra parameters to your popup view, you should use callback_data attribute for PopupViewField. This argument should be dictionary or OrderedDict. This dictionary containing yours parameters will be encoded to ASCII text string and added to url address. In your popup view You can take this parameters from request.GET.

popups.py ::

from django.views.generic import View
from django_popup_view_field.registry import registry_popup_view

class FooPopupView(View):
    def get(self, request):
        print(request.GET['extra_param'])  # --> will be "Foo Bar"
        print(request.GET['my_pk'])        # --> will be 666
        ....

# REGISTER IS IMPORTANT
registry_popup_view.register(FooPopupView)

forms.py ::

from django import forms
from django_popup_view_field.fields import PopupViewField

class FooForm(forms.Form):

    some_field = PopupViewField(
        view_class=FooPopupView,
        callback_data={
            'extra_param': 'Foo Bar',
            'my_pk': 666
        }
    )

Model ^^^^^^^ models.py ::

from django.db import models


class Country(models.Model):
    code = models.CharField(max_length=2, primary_key=True)
    name = models.CharField(max_length=256)


class ExampleUser(models.Model):
    first_name = models.CharField(max_length=30)

PopupView ^^^^^^^^^^ templates/myapp/popups/country.html ::

<ul>
    {% for country in countries %}

popups.py ::

class CountryPopupView(TemplateView):

template_name = "myapp/popups/country.html"
countries = None

def get(self, request, *args, **kwargs):
    self.countries = Country.objects.all()
