About

Flask-MongoEngine is a Flask extension that provides integration with MongoEngine. It handles connection management for your app. You can also use WTForms as model forms for your models.

Documentation

You can find the documentation at https://flask-mongoengine.readthedocs.io

Installation

You can install this package using pypi: pip install flask-mongoengine

Tests

To run the test suite, ensure you are running a local copy of Flask-MongoEngine and simply run: pytest.

To run the test suite on every supported versions of Python, PyPy and MongoEngine you can use tox. Ensure tox and each supported Python, PyPy versions are installed in your environment:

# Install tox
$ pip install tox
# Run the test suites

    Next Milestone Questions & Call for Maintainers!

    @anemitz & @thomasst do you guys have any plans for the next milestone / release of flask-mongoengine?

    Unfortunately, I dont have the time available at the minute to fix the issues and push a release. If you are in the same boat, I'm happy to try and draft in more maintainers!

    Any potential maintainers - please post here if you want to help further flask-mongoengine - I'm happy to mentor as well!

    i would love to be able to have a mongomock connection if app.config['TESTING'] is true this would allow easier testing of the flask application (otherwise an in-memory mongo like the one implemented in ming would be great)

    Hello, I think that the PyPI package needs to be updated. The stable branch contains changes since it was last uploaded (about year ago).

    Document and fix connection code

    Reverting/ fixing changes from https://github.com/MongoEngine/flask-mongoengine/pull/231. Relevant criticism: https://github.com/MongoEngine/flask-mongoengine/pull/231#issuecomment-255568259.

    The main goal of this PR is to fix a buggy connection code introduced in v0.8. It also makes the code cleaner and easier to understand through a better separation of responsibilities and a better documentation.

    This is unfortunately dropping support for mongomock, but many things were broken about it to begin with. We should revisit adding it in the future, though personally I don't see a point for it... In the age of Travis/CircleCI/etc., it's so easy to run a real MongoDB in your tests.

    Things to test manually:

    • [x] Connecting to multiple mongos in a sharded cluster
    • [x] Connecting to a replica set
    • [x] Connecting to a server that requires authentication
    • [x] All of the above via a MongoDB URI

    Fixes #266 #283 #282 #259 #258 #254 #250 #247 #267

    while assigning replicaSet parameter, the replicaSet is gone. This is because of the below code...

    In master branch, flask_mongoengine/connection.py, line 265:

    if conn_setting.pop('replicaset', None):
        resolved['replicaSet'] = conn_setting.pop('replicaset', None)
    

    what is f***ing going on lol

    Because dict.pop() will return and also remove specific key value pair from dict, so we cannot do dict.pop() twice. Actually this code should be:

    replica_set = conn_setting.pop('replicaset', None)
    if replica_set:
        resolved['replicaSet'] = replica_set

  • Model form generator now accepts wtf custom 'validators' and 'filters' on model field definition.

    Model form generator now accepts wtf custom 'validators' and 'filters' on model field definition.

    Added a wrapper sub-class WtfBaseField to allow additional WTForm field parameters and settings needed by flask-mongoengine, without necessarily going through to the core mongoengine BaseField.

    • flask_mongoengine/__init__.py has patching to redirect wtf mongoengine Fields of base BaseField to use WtfBaseField
    • wtf/orm.py now has 'validators' and 'filters' allowed on behalf wtf model field generator.

    Example:

     class Contact(db.Document)
        telephone = db.StringField(
            required=True,
            validators=[
              validators.InputRequired(message=u'Missing telephone.'),
            ],
            max_length=50

  • Omit CSRF token when populating model instance with form data (Fix #436)

    Omit CSRF token when populating model instance with form data (Fix #436)

    Fix #436

    When no model instance was provided to ModelForm, ModelForm.save() creates the model instance itself.

    Preivously, the instance was initialized with values from Form.data which contains all form fields. This causes an error with e.g. CSRF-protected forms, because an auxiliary parameter such as csrf_token is expected to be a field declared on the model. (The problem is also described here.)

    With this PR, the field values are passed via Form.populate_obj() instead of Form.data, as the method respects field-specific rules, i.e. omits CSRFTokenFields.

  • FieldDoesNotExist error when saving WTForms model form submitted with CSRF token

    FieldDoesNotExist error when saving WTForms model form submitted with CSRF token

    Bug

    When saving a WTForms model form that includes a CSRF token, the token is added as a field value to the model instance. E.g.:

    class MyModel(db.Document):
        pass
    MyForm = model_form(MyModel)
    form = MyForm(request.POST)
    form.save()
    

    With CSRF protection enabled, this raises an exception such as:

    mongoengine.errors.FieldDoesNotExist: The fields "{'csrf_token'}" do not exist on the document "MyModel"

    Expected behavior

    When saving the form submission, the CSRF token gets omitted, as it's not a declared field on the model.

  • Rewrite connection module

    Rewrite connection module

    I had a time to look at connection module, that originally was made in 2016-2017. In nearest past there was a lot of question and bugs related to connection. By my opinion our old connection module did a lot of work, that should not be done in this package at all. For example there is some things that by my opinion is not correct:

    • Setting of some connection defaults - we should not do it, as same defaults will be set in upstream mongoengine/pymongo packages. We do not do anything with these defaults, but do the work that hard to track. Also as it is hard to track changes in parent packages, that should be implemented here.
    • Replacing mongomock urls - in this package mongomock support was dropped in version 0.8.1, but mongomock settings handled by mongoengine upstream package. We should not try to do the work, that is done in package with much more contributtors.
    • Different behavior on dict or list settings - old implementation had two types in return of connection functions. In case one db used it was dict, in case of multiple dbs it was list. It is not correct and can be considered as unexpected behavior.

    So at the end this Pull request will:

    • Removed unexpected set of defaults. User is now fully responsible to set correct defaults, or defaults from upstream mongoengine and pymongo will be used.
    • Connection property of flask-mongoengine MongoEngine class now will always return dict with one or many database connections.
    • Connection handling now the same for one connection or many connections. Before this PR it was difference when 1 or many DB used.
    • Updated tests for new behavior.

    TODO before merge:

    • Documentation update

    Should fix:

    • #385
    • #381
    • #386
    • Probably #420

    I honestly hope for any comments, and for some test users, as it is deep flask-mongoengine behavior change. Code reviews are welcomed on any stage.
