dictionary to mongodb insert all data in one document-CodePudding

I try to import a CSV file in mongodb, but with my code, it inserts all in only one document:

file_path = tk.filedialog.askopenfilename()
mongo_client = MongoClient()
db = mongo_client.football

file_path2 = file_path   ".json"

df = pd.read_csv(file_path)  # loading csv file
df.to_json(file_path2)  # saving to json file
            
with open(file_path2) as f:
    file_data = json.load(f)

db.joueurs.insert_many([file_data])

I want to insert them in differents documents.

CodePudding user response：

Here is a way to read a CSV and load the data into a MongoDB collection. Assuming the data in the file is as follows:

col1,col2
a,1
b,2

The following Python and PyMongo code will create two documents in the collection.

data = []
file_name = "some.csv"

with open(file_name, newline='') as csvfile:
    reader = csv.DictReader(csvfile)    # using Python's csv module
    for row in reader:
        data.append(row)

result = collection.insert_many(data)

The resulting documents in the collection:

{ "_id" : ObjectId("626fc502c9bbf326c869f434"), "col1" : "a", " col2" : "1" }
{ "_id" : ObjectId("626fc502c9bbf326c869f435"), "col1" : "b", " col2" : "2" }
