Hi all
I'm pretty new to web2py and web development in general. I'm really stuck
with something and haven't been able to find a tutorial which can help me
out etc. I was wondering if some one could point me in the right direction.
I have three tables. I want to upload a csv, and update each table in
sequence, so a newly generated primary key can be passed to each
successive table.
(1)
db.define_table('study_info',
Field('title'))
One to
many relationship
(2)
db.define_table('core_data',
Field('study_info_id', 'reference study_info'),
Field('taxon_name', type = 'string',
comment='Classification of sample collected'))
(3)
db.define_table('sample_data',
One to many relationship
Field('Core_data_ID', 'reference'),
Field('value', type = 'double'))
So just to clarify , data gets entered into the first table, the primary
key from table 1 is then passed to the foreign key of 2, then same again
for 2 to 3.
I managed to the function working to update one table from a csv, but tried
a few things out from there but nothing worked. Would i somehow modify this
using a for loop?
def import_csv():
from gluon.sqlhtml import form_factory
form = SQLFORM.factory(Field('csvfile','upload',uploadfield=False))
if form.process().accepted:
db.study_info.import_from_csv_file(request.vars.csvfile.file)
redirect(URL('index'))
return dict(form=form)
Thanks in advance
Matt
