django-nominopolitan 0.0.15

Neapolitan with namespaces - Django CRUD views

Nominopolitan

This is an opinionated extension package for the excellent neapolitan package. It adds these features:

• Namespaced URL handling
• Display related field name (using str()) in lists and details (instead of numeric id)
• Support @property values in list view
• Separate create form if create_form_class specified
• Support for crispy-forms if installed in project
• Support for rendering templates using htmx
• Support for modal display of CRUD view actions (requires htmx and Alpine)
• Allow specification of base_template_path (to your base.html template)
• Allow override of all nominopolitan templates by specifying templates_path
• Support for extra_actions to add additional actions to list views
• Styled using bulma (I know, it would be better with tailwind - let me know if you want to help)
• Header title context for partial updates (so the title is updated without a page reload)
• Management command nm_mktemplate to copy required nominopolitan template (analagous to neapolitan's mktemplate)
• FYI it uses django-template-partials under the hood.

This is a very early alpha release; expect many breaking changes. You might prefer to just fork or copy and use whatever you need. Hopefully some or all of these features may make their way into neapolitan over time.

Installation

With pip: pip install django-nominopolitan

Poetry: poetry add django-nominopolitan

Configuration

Add these to your settings.py:

INSTALLED_APPS = [
    ...
    "nominopolitan", # put this before neapolitan
    "neapolitan",    # this is required to use the `NominopolitanMixin`
    ...
]

In addition:

1. If you want to set use_htmx = True, then make sure htmx is installed in your base template and django_htmx is installed.
2. If you want to set use_modal = True, it requires use_htmx=True (see above) and alpinejs is installed in your base template.

Usage

The best starting point is neapolitan's docs. The basic idea is to specify model-based CRUD views using:

# neapolitan approach
class ProjectView(CRUDView):
    model = projects.models.Project
    fields = ["name", "owner", "last_review", "has_tests", "has_docs", "status"]

The nominopolitan mixin adds a number of features to this. The values below are indicative examples.

from nominopolitan.mixins import NominopolitanMixin
from neapolitan.views import CRUDView

class ProjectCRUDView(NominopolitanMixin, CRUDView):
    # *******************************************************************
    # Standard neapolitan attributes
    model = models.Project
    fields = [
        "name", "project_owner", "project_manager", "due_date",
        ]

    form_class = forms.ProjectForm # standard neapolitan setting if needed
    # ...other standard neapolitan attributes
    # ******************************************************************
    # nominopolitan attributes

    fields = 'all' # if you want to include all fields
    fields = None # you can omit the fields attribute, in which case it will default to all fields

    properties = ["is_overdue",] # if you want to include @property fields in the list view
        # properties = 'all' if you want to include all @property fields

    # sometimes you want additional fields in the detail view
    detail_fields = ["name", "project_owner", "project_manager", "due_date", "description",]
        # or 'all' to use all model fields, or 'fields' to use the fields attribute
        # if you leave detail_fields to None, it will default to the same as in the fields attribute

    detail_properties = 'all' # if you want to include all @property fields
        # or a list of valid properties
        # or 'properties' to use the properties attribute

    namespace = "my_app_name" # specify the namespace 
        # if your urls.py has app_name = "my_app_name"

    create_form_class = forms.ProjectCreateForm # if you want a separate create form
        # the update form always uses form_class


    use_crispy = True # will default to True if you have `crispy-forms` installed
        # if you set it to True without crispy-forms installed, it will resolve to False
        # if you set it to False with crispy-forms installed, it will resolve to False

    base_template_path = "core/base.html" # defaults to inbuilt "nominopolitan/base.html"
    templates_path = "neapolitan" # if you want to override all the templates in another app
        # including one of your own apps; eg templates_path = "my_app_name/nominopolitan" 
        # and then place in my_app_name/templates/my_app_name/nominopolitan

    use_htmx = True # if you want the View, Detail, Delete and Create forms to use htmx
        # if you do not set use_modal = True, the CRUD templates will be rendered to the
        # hx-target used for the list view
        # Requires:
            # htmx installed in your base template
            # django_htmx installed and configured in your settings

    use_modal = True #If you want to use the modal specified in object_list.html for all action links.
        # This will target the modal (id="modalContent") specified in object_list.html
        # Requires:
            # use_htmx = True
            # Alpine installed in your base template
            # htmx installed in your base template
            # django_htmx installed and configured in your settings

    extra_actions = [ # adds additional actions for each record in the list
        {
            "url_name": "fstp:do_something",  # namespace:url_pattern
            "text": "Do Something",
            "needs_pk": False,  # if the URL needs the object's primary key
            "hx_post": True, # use POST request instead of the default GET
            "button_class": "is-primary", # semantic colour for button (defaults to "is-link")
            "htmx_target": "content", # htmx target for the extra action response 
                # (if use_htmx is True)
                # NB if you have use_modal = True and do NOT specify htmx_target, then response
                # will be directed to the modal 
        },
    ]

nm_mktemplate management command

This is the same as neapolitan's mktemplate command except it copies from the nominopolitan templates instead of the neapolitan templates.

It's the same syntax as neapolitan's mktemplate command:

python manage.py nm_mktemplate <app_name>.<model_name> --<suffix>

Status

Extremely early alpha. No tests. Limited docs. Suggest at this stage just use it as a reference and take what you need. It works for me.
