PostgreSQL/PostGISへのポリゴン座標

Question

私はポリゴン座標のgeojsonファイルを持っています。 psycopg2 apiを使用してpythonでpostgreSQLデータベースに座標を挿入しようとしています。ここで私は、彼らがこの形式である必要があるのpostgresに挿入する

"geometry": { "type": "Polygon", "coordinates": [ [ [ -74.0407457, 40.7130407 ], [ -74.0406424, 40.7130291 ], [ -74.0406471, 40.7130128 ], [ -74.0406625, 40.7130141 ], [ -74.0406659, 40.7130016 ], [ -74.0406531, 40.7129996 ], [ -74.0406377, 40.7129826 ], [ -74.0406401, 40.7129721 ], [ -74.04062, 40.7129693 ], [ -74.0406173, 40.7129823 ], [ -74.0405894, 40.7129785 ], [ -74.0405874, 40.7129932 ], [ -74.0405764, 40.7129914 ], [ -74.040574, 40.7129998 ], [ -74.040519, 40.7129937 ], [ -74.0405227, 40.7129752 ], [ -74.0404268, 40.712964 ], [ -74.0404235, 40.7129823 ], [ -74.0403662, 40.7129765 ], [ -74.0403675, 40.7129671 ], [ -74.0403578, 40.712966 ], [ -74.0403605, 40.7129508 ], [ -74.0403303, 40.7129475 ], [ -74.0403326, 40.7129368 ], [ -74.0403165, 40.7129348 ], [ -74.0403149, 40.7129465 ], [ -74.0402931, 40.7129571 ], [ -74.04028, 40.7129551 ], [ -74.040276, 40.7129698 ], [ -74.0402941, 40.7129737 ], [ -74.0402917, 40.7129805 ], [ -74.0403102, 40.7129828 ], [ -74.0403028, 40.7130151 ], [ -74.0403256, 40.7130184 ], [ -74.0403179, 40.7130608 ], [ -74.0403085, 40.7130596 ], [ -74.0403071, 40.7130669 ], [ -74.0402867, 40.7130646 ], [ -74.0402827, 40.7130875 ], [ -74.0402706, 40.7130862 ], [ -74.0402689, 40.7130962 ], [ -74.0402522, 40.7130944 ], [ -74.0402495, 40.7131083 ], [ -74.0402629, 40.7131104 ], [ -74.0402773, 40.7131251 ], [ -74.040275, 40.7131371 ], [ -74.040291, 40.7131388 ], [ -74.0402931, 40.7131256 ], [ -74.0403256, 40.7131292 ], [ -74.0403286, 40.7131144 ], [ -74.0403387, 40.7131155 ], [ -74.0403407, 40.7131078 ], [ -74.040398, 40.7131147 ], [ -74.040394, 40.713131 ], [ -74.0404902, 40.7131434 ], [ -74.0404939, 40.7131272 ], [ -74.0405492, 40.7131327 ], [ -74.0405469, 40.7131401 ], [ -74.0405573, 40.7131414 ], [ -74.0405546, 40.7131546 ], [ -74.0405864, 40.7131594 ], [ -74.0405841, 40.7131709 ], [ -74.0405978, 40.7131726 ], [ -74.0405998, 40.7131635 ], [ -74.040623, 40.7131516 ], [ -74.0406364, 40.7131531 ], [ -74.0406394, 40.7131363 ], [ -74.0406226, 40.7131343 ], [ -74.0406257, 40.7131211 ], [ -74.0407266, 40.713133 ], [ -74.0406843, 40.7133394 ], [ -74.0401087, 40.7132723 ], [ -74.0401036, 40.7132987 ], [ -74.0400151, 40.7132885 ], [ -74.0400165, 40.7132847 ], [ -74.0399266, 40.7132743 ], [ -74.0400315, 40.712747 ], [ -74.0407879, 40.7128354 ], [ -74.0407457, 40.7130407 ] ], [ [ -74.0400371, 40.7131942 ], [ -74.0401257, 40.7132042 ], [ -74.0401615, 40.7130218 ], [ -74.0400729, 40.7130118 ], [ -74.0400371, 40.7131942 ] ] ] } 

で働いている座標（以下座標はhttp://www.postgis.net/docs/ST_GeomFromText.htmlからです）

SELECT ST_GeomFromText('POLYGON((-71.1776585052917 42.3902909739571,-71.1776820268866 42.3903701743239, 
-71.1776063012595 42.3903825660754,-71.1775826583081 42.3903033653531,-71.1776585052917 42.3902909739571))'); 

がある基本的にリストはタプルであることが必要と座標ペアは緯度の長い値を区切るコンマを持つことができず、座標の周りに「または」がありません

このタイプのデータ形式を作成する方法を見つけることができません

私はこれを試してみました：

geojson = json.dumps(i['geometry']) 
qry = "insert into AbeBuildings (geom) values(ST_SetSRID(ST_GeomFromGeoJSON(%s), 4326));" 
cur.execute(qry,(geojson)) 

エラーが

{"type": "Polygon", "coordinates": [[[-74.0410635, 40.7112018], [-74.0409077, 40.7119448], [-74.0408936, 40.7119431], [-74.0402319, 40.7118572], [-74.0403913, 40.7111239], [-74.0406334, 40.711153], [-74.0405859, 40.7113794], [-74.0406154, 40.7113997], [-74.0407442, 40.7114119], [-74.0407737, 40.7113936], [-74.04082, 40.7111725], [-74.0410635, 40.7112018]], [[-74.0406941, 40.7118065], [-74.0407382, 40.7116013], [-74.0405315, 40.7115758], [-74.0404874, 40.711781], [-74.0406941, 40.7118065]]]}

    cur.execute(qry,(geojson)) 
TypeError: not all arguments converted during string formatting 

Answer 1

言うPsycopg2はあなただけで一つの値を指定し、リストまたはタプルする引数が必要です。 次のようにお試しください：

cur.execute(qry, (geojson,))
