Foirmeacha API GeodJangoLink to this heading#

\n

Soláthraíonn GeodJango roinnt réimsí foirme speisialaithe agus giuirléidí d'fhonn sonraí geolocálaithe a thaispeáint agus a chur in eagar ar léarscáil. De réir réamhshocraithe, úsáideann siad léarscáileanna OpenLayers faoi thiomáint, le bonn ciseal WMS a sholáthraíonn NASA.

Chomh maith leis na rialt:ref: argóintí réimse foirm <core-field-arguments>, glacann réimsí foirme GeodJango na hargóintí roghnacha seo a leanas.

\nField.sridLink to this definition#
\n

Is é seo an cód SRID ar chóir luach an réimse a athrú. Mar shampla, má tá an giuirléid léarscáileanna SRID difriúil ón SRID a úsáideann d'fheidhmchlár nó do bhunachar sonraí níos ginearálta, tiontóidh an réimse luachanna ionchuir go huathoibríoch go SRID sin.

max_geom_collectionsLink to this heading#

\n
\n
\nField.max_geom_collectionsLink to this definition#
\n
\n

The maximum number of geometry collections the field accepts before\nrefusing to parse the input and raising a\nValidationError. This guards against crashes\nin the underlying GEOS library when parsing deeply nested\nGEOMETRYCOLLECTION input. It defaults to 198.

\n

The limit is applied differently depending on the input format: for\nwell-known text (WKT) it bounds the nesting depth, while for well-known\nbinary (WKB and hex-encoded WKB) it bounds the total number of geometry\ncollections (both breadth and depth). As a result, the same value may\naccept a wide, shallow collection as WKT but reject it as WKB. For GeoJSON,\nthe limit is not applied at all, since GDAL parses that input type instead.

\n

Increase this value (or set to None) only if you must accept\nlegitimately deep geometries, since doing so reduces protection against\nfatal errors.
