"##;#   g F   " ,E e****,,HY Oc@dt|i|S)a Given a data source (either a string or a DataSource object) and a string model name this function will generate a GeoDjango model. Usage: >>> from django.contrib.gis.utils import ogrinspect >>> ogrinspect('/path/to/shapefile.shp','NewModel') ...will print model definition to stout or put this in a Python script and use to redirect the output to a new model like: $ python generate_model.py > myapp/models.py # generate_model.py from django.contrib.gis.utils import ogrinspect shp_file = 'data/mapping_hacks/world_borders.shp' model_name = 'WorldBorders' print(ogrinspect(shp_file, model_name, multi_geom=True, srid=4326, geom_name='shapes', blank=True)) Required Arguments `datasource` => string or DataSource object to file pointer `model name` => string of name of new model class to create Optional Keyword Arguments `geom_name` => For specifying the model name for the Geometry Field. Otherwise will default to `geom` `layer_key` => The key for specifying which layer in the DataSource to use; defaults to 0 (the first layer). May be an integer index or a string identifier for the layer. `srid` => The SRID to use for the Geometry Field. If it can be determined, the SRID of the datasource is used. `multi_geom` => Boolean (default: False) - specify as multigeometry. `name_field` => String - specifies a field name to return for the __str__() method (which will be generated if specified). `imports` => Boolean (default: True) - set to False to omit the `from django.contrib.gis.db import models` code from the autogenerated models thus avoiding duplicated imports when building more than one model by batching ogrinspect() `decimal` => Boolean or sequence (default: False). When set to True all generated model fields corresponding to the `OFTReal` type will be `DecimalField` instead of `FloatField`. A sequence of specific field names to generate as `DecimalField` may also be used. `blank` => Boolean or sequence (default: False). When set to True all generated model fields will have `blank=True`. If the user wants to give specific fields to have blank, then a list/tuple of OGR field names may be used. `null` => Boolean (default: False) - When set to True all generated model fields will have `null=True`. If the user wants to specify give specific fields to have null, then a list/tuple of OGR field names may be used. Note: Call the _ogrinspect() helper to do the heavy lifting.  )join _ogrinspect)argskwargss r ogrinspectr);s$H 99[$1&11 2 22r"NTc #Kt|trt|}n%t|trntd||} | jfd} | | | | | |} fd}|rdVdVdVdVd|zVt | j| j| jD]6\}}}}| }|dd d kr|d z }||}|tur6| | vr d ||||fzVed |d|dd dVy|turd |d|dd dV|turd |d|dd dV|turd |d||dV|turd |d|dd dV|turd |d|dd dV|t urd |d|dd dV#td|d|| j}|r||j}|*| jd}n%| jj}|d}n|dkrd}n d|z}nd|z}d |d|d|dV|r dVd|zVd Sd S)z Helper routine for `ogrinspect` that generates GeoDjango models corresponding to the given data source.
