MultipleChoiceCommaField - CheckboxSelectMultiple value sequence as a single string, comma-separated. Since I frequently want to store multiple-selected choice items as a single field in the model, I found it convenient to write a custom field class. The code uses the comma as a separator, but it could be easily generalized to use any delimiter.
This view will enable you to generate OpenOffice documents from templates written in OpenOffice 2.x Just make sure that there is no OO tag in between your code (no change in formatting etc.). content.xml is a valid XML file, so you can do some preprocessing using xml.dom.minidom. I would also recommend caching (just save the zip file without content.xml and content.xml on its own).
How to use it {% pycall os.path.abspath(".") %} {% pycall os.path.abspath(".") as path %} This is the {{ path }}. Syntax {% pycall module.function(...) [as variable_name] %} If there is no as variable_name, the result will be output directly.
Sometimes you need to see the json representation of an object, here is how I do it :)
As you can see, if you using django-rest-framework, you will found many different response format. This middleware to solve all of these problems with Standard API Response. All HTTP Response status stored into json response, not in HTTP Status (because mobile application, like android can't fetch the response body when HTTP Status >= 400).
Makes it possible to add a filtering condition directly after the aggregate function (or possible, `aggregate(expression) WITHIN GROUP (ordering clause)`. This is mostly useful if the annotation has two or more expressions, so it's possible to compare the result with and without the applied filter; it's more compact than using `Case`. It's suggested to add `values` to the queryset to get a proper group by. Usage example: `books = Book.objects.values('publisher__name').annotate( count=Count('*'), filtercount=Filter(expression=Count('publisher__name'), condition=Q(rating__gte=5)) ) ` Supported on Postgresql 9.4+. Possible other third-party backends.
Dynamic Paginator Mixin for Django 1.8.* - 1.9.*, also work for CBV (Class Bassed View) but not for "django generic view".
Fields that support HTML optgroups. Adapted from [this snippet](https://djangosnippets.org/snippets/1968/) and updated to work with latest version of Django (1.9) and additional ModelMultipleChoiceField support added. Example Usage: tag = GroupedModelChoiceField(queryset=Tag.objects.all(), group_by_field='parent') positions = GroupedModelMultiChoiceField(queryset=Position.objects.all(), group_by_field='agency')
I've reimplemented the code I found somewhere on the web within my models file. The earlier version was incapable of converting all formats to JPG while this code converts all formats and compresses all of them successfully. You need to have PILLOW installed for this to work.
`<h3>Page: {{ page.number }} of {{ page.paginator.num_pages }}</h3> {% if page.has_previous or page.has_next %} <div> {% if page.has_previous %} <a href="{% url_add_query page=page.previous_page_number %}">{% endif %}« Previous {% if page.has_previous %}</a>{% endif %} | {% if page.has_next %} <a href="{% url_add_query page=page.next_page_number %}">{% endif %} Next »{% if page.has_next %}</a>{% endif %} </div> {% endif %}`
A widget for a checkbox multi select, adapted from the RadioSelect widget, which allows you to iterate over each choice in the template rather than outputting the whole thing as a ul in one go. {{ form.field.label_tag }} {% for option in form.field %} <span>{{ option }}</span> {% endfor %}
This only works with Point geometry. [video](http://www.youtube.com/watch?v=gZ7_n177sTE&list=HL1351725584&feature=mh_lolz) Rename the snippet as gmgdav3.js and save it to template/admin with [gmgdav3.html](http://djangosnippets.org/snippets/2840/) * - *models.py*: ` from django.contrib.gis.db import models` ` class point(models.Model):` ` address = models.CharField(max_length=100, help_text='Press "Tab" to refresh the map')` ` longitude = models.FloatField(help_text='WGS84 Decimal Degree. Press "Tab" to refresh the map')` ` latitude = models.FloatField(help_text='WGS84 Decimal Degree. Press "Tab" to refresh the map')` ` in_geom = models.PointField('shp', srid=4326)` ` objects = models.GeoManager()` ` def __unicode__(self):` ` return str(self.address)` * - *admin.py*: ` from models import * ` ` from django.conf import settings` ` from django.contrib.gis import admin` ` from django.contrib.gis.geos import GEOSGeometry` ` class GoogleAdmin(admin.OSMGeoAdmin):` ` g = GEOSGeometry('POINT (9.191884 45.464254)') # Set map center` ` g.set_srid(4326)` ` g.transform(900913)` ` default_lon = int(g.x)` ` default_lat = int(g.y)` ` default_zoom = 7` ` extra_js = ["http://maps.google.com/maps/api/js?v=3.2&sensor=false"]` ` map_template = 'gmgdav3.html'` ` admin.site.register(point, GoogleAdmin)` ` # admin.site.register(your other models...,...)`
#### this is the right and working way

A *SimpleListFilter* derived class that can be used to filter by taggit tags in the admin. To use, simply add this class to the *list_filter* attribute of your ModelAdmin class. Ex.: class ItemAdmin(admin.ModelAdmin): list_display = ('name', 'unit', 'amount') list_filter = ('unit', TaggitListFilter) Based in [ModelAdmin.list_filter documentation](https://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.ModelAdmin.list_filter).
