I've been trying to use jqxUploadFiles but instead of php I need to use python.
In a code like below;
from flask import request
from flask.ext.uploads import UploadSet, configure_uploads, ALL
def upload_file():
files = UploadSet('files', ALL)
app.config['UPLOADED_FILES_DEST'] = '/uploads'
configure_uploads(app, files)
filename = files.save(request.files['files'])
return filename
where app = Flask(__name__)
but in this project there is;
main = Blueprint('main', __name__)
where it used like @main.route('/', methods=['GET', 'POST'])
and there is a create_app function;
def create_app():
app = Flask(__name__)
app.config.from_object(config['development'])
with app.app_context():
db.app = app
db.init_app(app)
db.create_all()
and it is used in manage.py file;
app = create_app()
manager = Manager(app)
def make_shell_context():
return dict(app=app, db=db)
manager.add_command("shell", Shell(make_context=make_shell_context))
@manager.command
def test():
"""Run the unit tests."""
import unittest
tests = unittest.TestLoader().discover('tests')
unittest.TextTestRunner(verbosity=2).run(tests)
if __name__ == '__main__':
manager.run()
So I need to use a function like "upload_file()" but I couldn't understand how "app" created by "create_app()" and Blueprint() relates to each other and how can I use it in upload_file().
At first, you had better make a file defined app
, and use it from other script file.
Using this app
, you can register Blueprint
object.
The example below is actually a script that worked.
app.py
from flask import Flask
app = Flask(__name__)
main.py
from flask import Blueprint
from flask_script import Server, Manager, Shell
from view import top
from app import app
app.register_blueprint(top.main)
if __name__ == '__main__':
app.run(host='192.168.33.40') # please change host
view/top.py
from flask import Blueprint
main = Blueprint("top", __name__, url_prefix="/")
from flask import request, render_template, redirect
from flask.ext.uploads import UploadSet, configure_uploads, ALL
from app import app
def upload_file():
files = UploadSet('files', ALL)
app.config['UPLOADED_FILES_DEST'] = '/tmp' # please change
configure_uploads(app, files)
filename = files.save(request.files['files'])
return filename
@main.route('/', methods=['GET'])
def index():
return render_template('top/index.html')
@main.route('upload', methods=['GET', 'POST'])
def upload():
upload_file()
return redirect('/')
templates/top/index.html
<form method=POST enctype=multipart/form-data action="/upload">
<input type=file name=files>
<input type=submit value=upload>
</form>
If you have any questions please ask anything!
