Required arguments: populate_from Specifies which field, list of fields, or model method the slug will be populated from. populate_from can traverse a ForeignKey relationship by using Django ORM syntax: populate_from = 'related_model__field' Optional arguments: separator Defines the used separator (default: '-') overwrite If set to True, overwrites the slug on every save (default: False) slugify_function Defines the function which will be used to "slugify" a content (default: :py:func:`~django.template.defaultfilters.slugify` ) It is possible to provide custom "slugify" function with the ``slugify_function`` function in a model class. ``slugify_function`` function in a model class takes priority over ``slugify_function`` given as an argument to :py:class:`~AutoSlugField`. Example .. code-block:: python # models.py from django.db import models from django_extensions.db.fields import AutoSlugField class MyModel(models.Model): def slugify_function(self, content): return content.replace('_', '-').lower() title = models.CharField(max_length=42) slug = AutoSlugField(populate_from='title') Inspired by SmileyChris' Unique Slugify snippet: https://www.djangosnippets.org/snippets/690/ csþ| dd¡| dd¡| dd¡}|dur6tdƒ‚n||_t|ƒsvt|ttfƒsX|f}tdd„|Dƒƒsvt d |ƒ‚| d t ¡|_ | d d ¡|_ | d d¡|_ | d ¡| dd¡|_| d¡| dd¡|_| d¡| dt¡|_tƒj|i|¤ŽdS)NÚblankTÚeditableFÚ populate_fromz missing 'populate_from' argumentcss|]}t|tƒVqdSr)rÚstr)rÚerrrÚ £r*z)AutoSlugField.__init__..zB'populate_from' must be str or list[str] or tuple[str], found `%s`Úslugify_functionÚ separatorú-Ú overwriteÚoverwrite_on_addÚallow_duplicatesÚmax_unique_query_attempts)Ú setdefaultÚpoprÚ_populate_fromÚcallablerÚlistÚtupler"Ú TypeErrorr rJrKrMrrNrOÚMAX_UNIQUE_QUERY_ATTEMPTSrPÚsuperÚ__init__)rr7r8rF©r/rrrZ•s*        zAutoSlugField.__init__cCs:dt |j¡}t d||j|¡}t d||fd|¡S)a  Clean up a slug by removing slug separator characters that occur at the beginning or end of a slug.
