flask-mongoengine

问题 The journey with Flask, MongoDB and MongoEngine continues. I've (hopefully) synced up the database with my model in a normal fashion, yet when I attempt to query the database for something as simple as an address name, I get this message: mongoengine.errors.InvalidQueryError InvalidQueryError: Not a query object: {'wsgi.multiprocess': False, 'SERVER_SOFTWARE': 'Werkzeug/0.9.6', 'SCRIPT_NAME': '', 'REQUEST_METHOD': 'GET', 'PATH_INFO': '/result', 'SERVER_PROTOCOL': 'HTTP/1.1', 'QUERY_STRING':

问题 I am running Flask with uwsgi threaded mode with processes 4 and using pymongo also flask_mongoengine and uwsgi says "MongoClient opened before fork. Create MongoClient only " I tried connect with connect=False but the result is same lazy-apps = true problem is fixed but it seems that uwsgi needs more time to load what can be done for best performance ? 回答1: app.config['MONGODB_SETTINGS'] = {'DB': 'somedb', "USERNAME": "dbadmin", "PASSWORD":"somepass",'connect': False} And client =

问题 I keep getting the above mentioned error. I have deleted the existing db field id which was set to unique. But on save I got the below exception raise NotUniqueError(message % unicode(err)) NotUniqueError: Tried to save duplicate unique keys (E11000 duplicate key error index: test.users.$id_1 dup key: { : null }) My user table looks like, class Users(db.Document, UserMixin): name = db.StringField(max_length=50) email = db.StringField(max_length=255) password = db.StringField(max_length=255)

问题 I'm just staring out with MongoDB and I'm staring an application with flask-mongoengine and I want to aggregate a few documents. I'm using flask-mongoengine and when trying class MyDocumentModel(db.Document): name = db.StringField(max_length=55) MyDocumentModel.objects.aggregate() I get the error: AttributeError: 'BaseQuerySet' object has no attribute 'aggregate' 回答1: Starting with mongoengine v0.9 (which is currently in development), you will be able to use aggregate() , like you suggested:

问题 I am facing trouble with loading configuration in Flask. from config import config, DevelopmentConfig, TestingConfig, ProductionConfig def create_app(config_name): app = Flask(__name__) app.config.from_object(config[config_name]) # Doesnot load configuration app.config.from_object(DevelopmentConfig) # Loads configuration succesfully. I have checked the type of config[config_name] etc. They are just fine. config file is given as follow. There are no issues with import, object types. If passed

问题 Based on this tutorial I am trying to create a form to get a few measurements. It seems that the part to display the data is working but when using the model_form command to generate the input form it breaks with this error: File "/myproject/lib/python3.4/site-packages/flask_mongoengine/wtf/orm.py", line 49, in convert 'description': field.help_text or '', AttributeError: 'ObjectIdField' object has no attribute 'help_text' The error happens on this line of my code: form_cls = model_form

问题 I've been working with Flask and MongoEngine, and I am having trouble when trying to save an object because of a ReferenceField. This is what my model looks like: class User(UserMixin, db.Document): first_name = db.StringField(max_length=255, required=True) last_name = db.StringField(max_length=255, required=True) email = db.StringField(max_length=255) class Post(db.Document): description = db.StringField(max_length=255, required=True) inserted_at = db.DateTimeField(default=datetime.datetime

问题 I've been using mongoengine for a while now and have a ton of python data processing code that relies on a common set of Object Document Models. Now I need to access the same mongodb instances from Flask. I'd like to use the same ODM definitions. class User(Document): email = StringField(required=True) first_name = StringField(max_length=50) last_name = StringField(max_length=50) The problem is that flask-mongoengine requires you to first set up your flask context "db" and then build your ODM
