iterating through form fields with rows

[aetag...@gmail.com]

I have a table defined with 3 input fields and then an upload field. The upload field is used to take the values that are entered by the user and input them into a file which contains all form field values from the session.

The form is generated dynamically, so the number of form fields varies with each session. 

I am stuck on figuring out how to capture the individual form field values. I am unsure if maybe I should be reading these into an array and then populating the file? 

If the form that is generated contains only one instance of the form fields, I can grab these values by doing row.field1, row.field2, row.field3.

I was wondering if web2py contains a method for dealing with the multiple instances of form fields?

For example, if the user created two instances of the form fields I would capture values like this:

row.field1_0, row.field2_0, row.field3_0

row.field1_1, row.field2_1, row.field2_1

However this does not work..

I have tried doing variations of the following:

for i in row.field1:

    print row.field1

When I run this with a session containing the form with two instances of form fields it will show me the values that were inputted for that session in field1_0, as well as field1_1. So I am able to at least see that it is capturing the separate entries in the single form. I am just not sure how can I can iterate through the form fields or if there is a keyword or method within web2py which will allow me to do this so I can place them accordingly before the file is uploaded.

for i in range(0, number_of_total_fields):

    row[field+i]

Hi!

Just for clarity: 

row.field_name - access to field value of record retrieved from DB ( by db().select() ) 

form.vars.field_name - access to field value of submitted form (  after form.process() )

form.vars - just a Storage() object  like a dict()

form.vars.keys() - list of all field_names

form.vars.values() - list of all field_values

What worked for me was utilizing row.values(), because I was doing this within the models file!

I haven't been able to find any documentation in regards to using it but that is what I was looking for! Thank you!
