I am developing a API which will return entries from a Database. I am using Flask-SQLAlchemy, Flask-Marshmallow, Flask-Admin and Docker to package it all up.
In one file Packages.py I have the following code regarding the database. The class PckagesSchema is the class I've added when trying to get Flash-Marshmallow working.
class Packages(db.Model):
id = db.Column(db.Integer, primary_key=True, autoincrement=True)
trackingnumber = db.Column(db.String(15))
email = db.Column(db.String(80))
localid = db.Column(db.String(80))
class PackagesSchema(ma.ModelSchema):
class Meta:
model = Packages
The in the main file I have the following snippets of code
from app.models import Packages, PackagesSchema
packages_schema = PackagesSchema()
db.create_all()
and then further down the part which will deal with API GET Requests.
@app.route('/packages', methods=['GET'])
def get_packages():
result = packages_schema.dump(Packages).data
return jsonify(result)
at the moment this returns:
{
"email": "Packages.email",
"localid": "Packages.localid",
"trackingnumber": "Packages.trackingnumber"
}
However, there is definitely something in the database as the Flask-Admin app displays its.
This is my first day working with Flask-Marshmallow so I am not that experienced at all and would appreciate any help. I have read https://flask-marshmallow.readthedocs.io/en/latest/ but still stuck.
I just brushed up a little on marshmallow:
@app.route('/packages', methods=['GET'])
def get_packages():
packages = Packages.query.all()
result = packages_schema.dump(packages).data
return jsonify(result)
Should give you everything in there. If you are returning many records, you need to add packages_schema = PackagesSchema(many=True)
.
Also, not sure what version of flask you are running... but pre the latest release, I dont think jsonify would work here since you could not call it on a list. Juts a heads up.
