Re: [web2py] Validating form fields manually

[Mandar Vaze]

Hi,

I have two scenario that require manual validation - Adding a new record 
and updating existing record.
Record only has two fields. It is an associative table for many-to-many 
relationship. I need to ensure that this pair is unique (I considered using 
primarykey=['task', 'owner'] - but it has other problems) 

Since the validation is same, i thought I could use the same function for 
both new/update.
The validation works for "new" but doesn't work for update. 
I allow only 'owner' to be modified - 'task' is shown on the form but it is 
read-only.

After some digging I found that, form.vars does not have 'task' -read-only 
field from the form.
Is there a way get the read-only field from "form" object ?

Any other suggestions for ensuring that task/owner pair is unique during 
update ?

-Mandar

Re: [web2py] Validating form fields manually

[Bruno Rocha]

You can read the read-only or hidden fields from the form directly on
request.vars, instead of form.vars use request.vars and it should work.
