Some comments:
In FK there is already stuff for error formatting. For example, if there's an error, the input tag will contain class="error" so you can mark that as "red" or something (look in the examples). Also, it's easier on your typing if you make a short-name reference to the form object in your local name space, like "f = self.form". Then you can just do f.lname.tag().
But there's nothing "wrong" with what you're doing; there's just already some plumbing for some of it.
This seems to work though I have a couple of questions about it.
1. When I click on the Submit button, if I do not enter a Middle Name, the form will not POST successfully. That is strange considering that Middle Name is not mandatory. If I enter anything in Middle Name, the form will POST. The only difference I can see between Middle Name and the other fields is that it is not mandatory and as such, I do not test for an error condition. How can I get the form to POST with a blank Middle Name field?
Hmm. That shouldn't happen. It's possible that it's getting confused by the lack of a Validator set declaration in the constructor of your field. IE,
newForm.addField(Fields.TextField('mname',label="Middle Name"))may have to be:
newForm.addField(Fields.TextField('mname', [ ], label="Middle Name"))If that's the case, that's a bad bug on our parts. Send me your actual code and I'll take a look.
2. I am using SQLObject to map the PostgreSQL tables to Python objects. I have that part prototyped and working. Once I get past the hurdle above, I have to transfer the contents of the form fields above to the Person object attributes. According to the Class Reference, I think I should be using self.form.value(fieldName) to do this. e.g.
if self.form.isSuccessful(): newPerson = Person( firstName = self.form.value(fname), middleName = self.form.value(mname), lastName = self.form.value(lname), )
... where Person is a SQLObject class corresponding to a PostgreSQL table. Am I on the right track?
That will certainly work. Alternatively, you can poke at each field:
newPerson = Person(
firstName = self.form.fname.value(),
middleName = self.form.mname.value(),
[etc]
)Or, better yet, just get the whole values bundle as a dictionary:
values = self.form.values()
newPerson = Person( firstName=values['fname'], middleName=values['mname'] ) etc...
