[英]Insert data into with pymongo and flask
when i click on submit button i get an error which says: 当我单击提交按钮时,出现错误提示:
"TypeError: 'Collection' object is not callable. If you meant to call the 'insert' method on a 'Database' object it is failing because no such method exists."
“ TypeError:'Collection'对象不可调用。如果您打算在'Database'对象上调用'insert'方法,则该方法将失败,因为不存在这样的方法。”
here is my signin.py code : 这是我的signin.py代码:
from flask import Flask, request, render_template
from pymongo import MongoClient
@app = Flask(__name__)
connection = MongoClient()
db = connection.project #database name.
collection = connection.signup # collection name.
@app.route('/signin/')
def index_show():
return render_template('signin.html')
@app.route('/signin/', methods = ['POST'])
def signup_form():
username = request.form['user']
passowrd = request.form['pass']
collection.insert({'user': username, 'passoword': passowrd})
if __name__ == '__main__':
app.run(debug = True)
my html file code is here : 我的html文件代码在这里:
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>
<form method="post" action=".">
<input type="text" name="user" /><br/><br/>
<input type="password" name="pass" /><br/><br/>
<input type="submit" name="submit" /><br/><br/>
</form>
</body>
The method has been deprecated and is changed to .insert_one()
in the pymongo 3.x driver, there is also .insert_many()
for multiple document creation: 该方法已被弃用,并在pymongo 3.x驱动程序中更改为
.insert_one()
,还有.insert_many()
用于创建多个文档:
collection.insert_one({'user': username, 'passoword': passowrd})
The .insert()
method is now only supported in the 2.x and lower series. 现在,仅2.x及更低版本中支持
.insert()
方法。
I think, the root cause is in this line: 我认为,根本原因在于:
collection = connection.signup # collection name.
Contrary to the comment, you're getting a DB named signup
. 与注释相反,您得到一个名为
signup
的数据库。 That should rather be: 那应该是:
collection = db.signup
please do make sure that you do this to an existing database,object has been returned successfully. 请确保对现有数据库执行此操作,对象已成功返回。 here is my code:
这是我的代码:
from pymongo import MongoClient
client=MongoClient()
db=client.testdb
new={"shopclues":1234,"rating":3}
result=db.testdb.insert_one(new)
result.inserted_id
ObjectId('59e2f0f2031b4b0b27ecfa09')
