[web2py] Re: How to represent dynamic fields in table
On a related note, is there a way to control the order/ sequence of the generated fields?

[web2py] Re: How to represent dynamic fields in table
The problem is that a set comprehension is being used, when it should be a
list comprehension.
Instead of:
*{Field(name,...) for name in fields}
it should be:
*[Field(name,...) for name in fields]

Try:

Here is complete definition of tables:
fields=[]

fields.append(row.effort_month.strftime('%b_%Y'))
db.define_table(monthly_projections,
Field('employee', 'reference auth_user', default=auth.

Field('costcode', 'reference costcodes', notnull=True),
*{Field(name, 'integer', default=0, represent = lambdavalue
, row: DIV(value if value else '-',_class='month', _id=str(row.id) +'.'+
name)) for name in fields}
)
Thanks for your help,

Thank you Anthony, that worked like a charm. Is this technique I should
learn in Python or Web2Py?

That's just Python. When the lambda's are called, they get the value of
name from the scope in which they were defined, so all the lambdas will use
the last value of name, which is the last month. Instead, you should pass
in name as an argument to each lambda, which will put it in the scope of
the lambda.
