Hello All,
Just started to learn web2py and here is an idea that I am trying to
implement. Users creates scenarios, which includes an uploaded file.
After the new scenario is created, the uploaded file should be processed
and computed values written to results table.
So far, I am successful in creating the scenarios and uploading the files.
But, I am not sure where I would write the controller
form.process().accepted.
By the way, I am using SQLFORM.grid and here is complete code. Any help
and/or pointers is highly appreciated.
-----------------
db.py
from gluon.tools import *
db=DAL("sqlite://storage.sqlite")
auth = Auth(db)
auth.define_tables(username=True)
crud = Crud(db)
db.define_table("scenario",
Field('title'),
Field('body', 'text'),
Field('created_on', 'datetime', default=request.now),
Field('created_by', 'reference auth_user', default=db.auth_user.id),
Field('file', 'upload'),
Field('file_status', default='file uploaded'))
db.scenario.created_by.requires=IS_IN_DB(db, db.auth_user.id)
db.scenario.title.requires = IS_NOT_EMPTY()
db.scenario.created_on.readable = False
db.scenario.created_by.readable = False
db.define_table("results",
Field('scenario_id', 'reference scenario'),
Field('amps', 'double'),
Field('volts', 'double'))
default.py
@auth.requires_login()
def index():
query = (db.scenario.created_by == auth.user.id)
grid = SQLFORM.grid(query, selectable=lambda ids: [])
return dict(grid=grid)
default/index.html
{{extend 'layout.html'}}
{{if auth.user.id:}}
<h2>Your Current Scenarios</h2>
{{=grid}}
{{pass}}
------------------
I tested the following code and see that the "form accepted" is flashed.
But, how do I link this form to the "Add" button in the SQLFORM.grid
def scenario():
form = SQLFORM(db.scenario)
if form.process().accepted:
response.flash = "form accepted"
##get the uploaded file, process and write results
return dict(form=form)
Thanks,
PT
