Django Management Command To Generate Model Data

Dilla is a command that populates your database with randomized data. You'll need install dilla as an app in the django settings file.

Examples:

  1. Generate data for all models in an app

    python manage.py dilla app_name

  2. Generate data for all models in all apps listed

    python manage.py dilla app_name app_name

  3. Generate data for all models in all apps listed (an alternative to #2)

    python manage.py dilla -a app_name -a app_name

  4. Generate data for supplied models, in the supplied apps

    python manage.py dilla -a app_name -m ModelName

  5. Addition to #4, generate data for multiple models

    python manage.py dilla -a app_name -m ModelName -m AnotherModelName

** The order of app names and model names are important, if a model has a ForeignKey to another model, but there isn't data available yet in the foregn table, problems occur.

** When using -a or -m, you don't need to use full python path.

You configure your models with some information for dilla. Here's some examples:

--models.py:--

class DillaController():

(Optional) this defines the order of how models are populated. (Fixes cross ForeignKey problems)

models=('UserProfile','Venue','Event','Genre','Artist')

class Event(models.Model): venue=models.ForeignKey('Venue') artists=models.ManyToManyField('Artist') date=models.DateTimeField(blank=False,null=False) showtime=models.TimeField(blank=False,null=False) doortime=models.TimeField(blank=False,null=False) covercharge=models.DecimalField(decimal_places=2,max_digits=7) created_at=antaresia_models.ModelCommons.created_at() updated_on=antaresia_models.ModelCommons.updated_on()

usual Dilla meta class

class Dilla():
    skip_model=False
    generate_images=False
    image_fields=None
    resolution="1024x768" #if images, this resolution
    resolutions=('300x340','200x190','100x10','200x90') #if images, use a random resolution from this tuple
    field_extras={ #field extras are for defining custom dilla behavior per field
        'fieldname':{
            'generator':None, #can point to a callable, which must return the desired value. If this is a string, it looks for a method in the dilla.py file.
            'generator_wants_extras':False, #whether or not to pass this "field extra" hash item to the callable
            'random_values':("word","yes","no","1"), #choose a random value from this tuple
            'resolution':'1024x768', #if images, use this image size for this field
            'resolutions':('300x340','200x190','100x10','200x90'), #if images, use a random size from this tuple
            'max':10, #for many to many fields, the maximum associated objects will be 10, so it will take a range like: Model.objects.all().order_by("?")[0:random.randrange(0,max)]
            'spaces':False, #if Char/TextField, whether or not to allow spaces
            'word_count':1, #if Char/TextField, the number of words to generate
            'word_range':(3,7), #a range of words to generate (3-7 words)
            'paragraph_count:1, #if TextField, the number of paragraphs to generate
            'paragraph_range':(3,5), #a range of paragraphs to generate (3 - 5 paragraphs)
            'integer_range':(0,2), #a range for any integer type field (IntegerField,SmallIntegerField,PositiveInteger,PositiveSmallInteger)
            #TODO:'digits_only':True, #if Char/TextField, but want numbers only
            #TODO:'digit_range:(30,400), #a range for digit only creation (default range is (0,9999))
            #TODO:'digit_ranges':((0,20),(30,300)), #chooses random range from this tuple.
            #TODO:'digits_for_words':False|True (Default:False) #generates lipsum words, but then replaces each word with numbers. (like a sentance of numbers)
        },
        'anotherfieldname':{...}
    }
