django-utensils =============== A collection of reusable components to help build Django projects. Installation ------------ To install the latest stable release: :: pip install django-utensils To get the latest dev version, install directly form GitHub like so: :: pip install -e git://github.com/code-kitchen/django-utensils.git#egg=django-utensils Many of the template tags require the ``request`` object. You need to add 'django.template.context\_processors.request' (Django 1.6 and 17) or 'django.template.context\_processors.request' (Django 1.8) to the template context processors in your settings. To use the ``AddressedModel`` you will need to add ``countries_plus`` to your ``INSTALLED_APPS`` setting. Forms ----- ``SearchForm`` ~~~~~~~~~~~~~~ Generic search form that can be used on any page. Used by ``viewmixins.SearchFormMixin``. ``UniqueModelFieldsMixin`` ~~~~~~~~~~~~~~~~~~~~~~~~~~ Mixin that enforces unique fields on ModelForm form fields. Must be left of ModelForm when defining the form class (see https://code.djangoproject.com/ticket/13075). There are two ways to list your unique fields depending on whether or not you want case insensitivity. .. code:: python unique_fields = ['name', 'username'] unique_fields = ['name', {'field': 'username', 'case_insensitive': True}] Middleware ---------- Hidden site ~~~~~~~~~~~ By adding ``utensils.middleware.HiddenSiteMiddleware`` to your ``MIDDLEWARE_CLASSES`` you can prevent people from viewing your site unless they use a query string parameter. The parameter is not needed for subsequent visits (unless cookies are cleared). This is a quick and simple method to keep prying eyes off your staging server for example. Provide the parameter name in the settings variable ``HIDDEN_SITE_SECRET``. For example: .. code:: python MIDDLEWARE_CLASSES += ('utensils.middleware.HiddenSiteMiddleware',) HIDDEN_SITE_SECRET = 'whisky' Using the built-in development server browsing to http://localhost/ will give the message "ACCESS DENIED". Browing to http://localhost/?whisky will succeed. Subsequent visits to http://localhost/ (no ``?whisky``) with the same browser will succeed until cookies are cleared or the cookie expires (currently set to a year). View mixins ----------- Collection of mixins for class-based views. List view pagination ~~~~~~~~~~~~~~~~~~~~ The ``PaginateMixin`` returns the paginate by setting used by the pagination template tag ``{% pagination %}`` so the Django ``ListView`` functions can use it. You will need to add ``utensils.context_processors.pagination`` to your context processors for the template tag to work. Set ``settings.PAGINATION_PAGE_SIZES`` to control the page size, if not set the default ``[20, 50, 100]`` is used. List view ordering ~~~~~~~~~~~~~~~~~~ The ``OrderByMixin`` allows easy ordering of list views. By including it the template tag (``{% order_by 'field_name' %}``) is given sorting context variables to work with. ``get_queryset`` is overidden to make use of these and order the object list. Generic single-field search ~~~~~~~~~~~~~~~~~~~~~~~~~~~ The ``SearchFormMixin`` provides a handy way to add search to list views. Add the ``search_form`` manually in your template or use the included fragment ``{% include 'fragments/_search.html' %}``. Specify the fields you wish to search on, and how, by including a ``search_fields`` dictionary on your view like so: .. code:: python class CustomerListView(SearchFormMixin, ListView): model = Customer search_fields = { 'user__email': 'icontains', 'first_name': 'icontains', 'last_name': 'icontains', 'postal_code': 'icontains', } ``MessageMixin`` ~~~~~~~~~~~~~~~~ By including and providing ``success_message`` and/or ``error_message`` attributes on your view class, messages will be added automatically to the request objects on events suchs as valid and invalid forms and formsets, object deletion etc. ``PermissionRequiredMixin`` ~~~~~~~~~~~~~~~~~~~~~~~~~~~ This mixin verfies the user is logged in and has the required permissions to access the view. It's a modified version of the django-braces mixin with an added bypass. Setting ``permission_required = False`` allows you to skip the check whilst keeping the mixin in a base view used across a project, for example. Settings: - ``permission_required`` - the permission to check for or False to skip check - ``login_url`` - the login url of site - ``redirect_field_name`` - defaults to "next" - ``raise_exception`` - defaults to False - raise 403 if set to True ``RedirectToNextMixin`` ~~~~~~~~~~~~~~~~~~~~~~~ If a ``next`` query string parameter is preset on a ``post()`` call it is assigned to the instance ``success_url``. ``StaffViewMixin`` ~~~~~~~~~~~~~~~~~~ Combines ``MessageMixin``, ``RedirectToNextMixin``, ``StaffuserRequiredMixin`` (from django-brances), ``PermissionRequiredMixin`` to create a useful mixin that can be used on all staff views. Views ----- ``BaseListView`` ~~~~~~~~~~~~~~~~ This view combines the pagination, order by and search mixins and adds an optional query set filter description that your templates can use. .. code:: python class ActiveCustomerList(BaseListView): filter_description = u"Active" queryset = Customer.active.all() .. code:: html {% block content %} <h2> {% if filter_description %} {{ filter_description|title }} customers {% else %} Customers {% endif %} </h2>  {% end block %} Yields: .. code:: html <h2>Active customers<h2>  ``SetModelFieldView`` ~~~~~~~~~~~~~~~~~~~~~ This view can be used to set the value of a field on a model instance. GET will display a template (and should be used as a confirmation page) and the value will be set on POST. The view uses ``django.views.generic.detail.BaseDetailView`` to provide ``get_object()``. .. code:: python class CustomerInactiveView(SetModelFieldView): """ Ask the user if they're sure they want to make the customer inactive. If they confirm by submitting the form set is_active to False and save. """ model = Customer field = 'is_active' value = False template_name = "customers/customer_inactive.html" If you require more control and want to introduce some logic when selecting the value or field to alter you can override ``get_field()`` and ``get_value()`` instead of setting the ``field`` and ``value`` class attributes. Storage ------- S3 ~~ The ``storage`` modules provides a way to easily store static or media files on Amazon S3. To use you will need to update your ``settings`` with the appropriate configuration, something like this: .. code:: python AWS = { 'STATIC': { 'location': 'static', # AWS_LOCATION 'querystring_auth': False, # AWS_QUERYSTRING_AUTH 'default_acl': 'public-read', # AWS_DEFAULT_ACL }, 'MEDIA': { 'location': 'media', # AWS_LOCATION 'querystring_auth': True, # AWS_QUERYSTRING_AUTH 'default_acl': 'private', # AWS_DEFAULT_ACL }, } AWS_ACCESS_KEY_ID = 'XXXXXXXXXXXXXXXXXXXX' AWS_SECRET_ACCESS_KEY = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX' AWS_STORAGE_BUCKET_NAME = 'bucket' AWS_PRELOAD_METADATA = True AWS_S3_SECURE_URLS = False STATICFILES_STORAGE = 'utensils.storage.StaticRootS3BotoStorage' DEFAULT_FILE_STORAGE = 'utensils.storage.MediaRootS3BotoStorage' Miscellaneous utils ------------------- There are utility functions in the ``utils`` module that deal with a range of things. Some are used by other parts of the library.
