Keyword Arguments: `geom_name` => The name of the geometry field to use for the model. `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. `multi_geom` => Boolean (default: False) - specify as multigeometry. �>Data source parameter must be a string or a DataSource object.���N�_�field) � isinstance�strr � TypeError�fields�lower� geom_type�to_multi�upper)� data_source� geom_name� layer_key� multi_geom�_mappingr �mfield�gtype� r �d/home/gouroczh/virtualenv/pat/3.9/lib/python3.9/site-packages/django/contrib/gis/utils/ogrinspect.py�mapping s$ � r c O s d� t| 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)�args�kwargsr r r � ogrinspect: s Dr& NTc # s� t | t�rt| �} nt | t�r ntd��| | } | j��fdd�} | | ��| | �� | |�} � �fdd�}|r�dV dV dV dV d | V t�| j| j| j�D �]N\}}}}|� � }|d d � d kr�|d 7 }||�}|t u �r |� � | v �rd||||f V nd||dd � f V q�|t u �r>d||dd � f V q�|t u �r`d||dd � f V q�|t u �r|d|||f V q�|tu �r�d||dd � f V q�|tu �r�d||dd � f V q�|tu �r�d||dd � f V q�td||f ��q�| j}|�r|�� |j}|d u �r\| jd u �r*d}n0| jj}|d u �rBd}n|dk�rRd}nd| }nd| }d|||f V |�r�dV d | V d S ) z� Helper routine for `ogrinspect` that generates GeoDjango models corresponding to the given data source.
