I have a Lealfet map in a Laravel Blade view where the user can draw shapes and markers. These features are registered in a GeoJson object, that I stringify and insert in a hidden textarea with name "geojson" to submit it to the server, within a form.
The problem is that I want to save this data as geometry type in my PostgreSQL database, using the PostGis ST_GeomFromGeoJSON() function, but I can't get it to work.
Here is what I tried for now:
$site = new Site;
$data = $request->all();
unset($data['geojson']);
foreach($data as $key=>$d)
{
$site->$key = $d;
}
$geojson = json_decode($request->geojson);
$site->save();
DB::update('update posha_sites set geom = ST_GeomFromGeoJSON(?)
WHERE num_site = ?
AND city_id = ?',
[$geojson, $request->num_site, $city_id->id]
);
Right now I am saving all my data and then trying to insert the geospatial data, as I don't know how I could use a raw query while saving the rest of my data.
When I do that I am getting this error:
Object of class stdClass could not be converted to string
EDIT
Here is the whole migration for the posha_sites table:
public function up()
{
Schema::create('posha_sites', function (Blueprint $table) {
$table->bigIncrements('id');
$table->string('name');
$table->bigInteger('num_site');
$table->string('type', 50)->nullable();
$table->mediumText('adresse')->nullable();
$table->string('cartes_anciennes')->nullable();
$table->string('carte_topo')->nullable();
$table->mediumText('cadastre_remembre')->nullable();
$table->mediumText('cadastre_moderne')->nullable();
$table->mediumText('cadastre_ancien')->nullable();
$table->string('lieu_dit')->nullable();
$table->mediumText('nature_parcelles')->nullable();
$table->mediumText('conditions_acces')->nullable();
$table->string('situation_administrative')->nullable();
$table->string('altitude')->nullable();
$table->string('relief')->nullable();
$table->mediumText('hydrographie')->nullable();
$table->string('geologie')->nullable();
$table->string('vestiges_periode')->nullable();
$table->mediumText('vestiges_nature')->nullable();
$table->mediumText('vestiges_conservation')->nullable();
$table->longText('plans_documents_figures')->nullable();
$table->longText('sources_manuscrites')->nullable();
$table->longText('sources_imprimees')->nullable();
$table->longText('renseignement_oral')->nullable();
$table->longText('bibliographie')->nullable();
$table->longText('histoire')->nullable();
$table->longText('historiographie')->nullable();
$table->longText('description_histoire_monumentale')->nullable();
$table->geometrycollection('geom')->nullable();
$table->string('last_author')->nullable();
$table->integer('tree_id')->unsigned()->nullable();
$table->integer('parent_id')->unsigned()->nullable();
$table->integer('city_id')->unsigned();
$table->timestamps();
});
}
The function ST_GeomFromGeoJSON() is in fact expecting a string so I didn't decode my $geojson variable:
$geojson = $request->geojson;
instead of:
$geojson = json_decode($request->geojson);
But I still get an error:
SQLSTATE[XX000]: Internal error:
7 ERROR: invalid GeoJson representation (SQL: update posha_sites set geom = ST_GeomFromGeoJSON({"type":"FeatureCollection","features":[{"type":"Feature","properties":{},"geometry":{"type":"Point","coordinates":[-0.229114,44.564488]}}]}) WHERE num_site = 248 AND city_id = 5)
Yet I tested my geojson in an online geojson validator and it seems correct.
