[web2py] Making a field non-editable, but writable using SQLFORM
I have a situation where I need to adjust an SQLFORM field to be non-editable. I can do that with .writable = False, but that seems to also prevents database I/O for that field. What I'm trying to do is set a default that cannot be changed. Is there a way to set an SQLFORM field so that it appears as a label on the form itself, but is still writable for the database? For reference, I'm doing this with a field in the form returned by auth.register, so I cannot insert code between the form creation and the accepts call. I believe I'm restricted to working with the model before calling auth.register, or by using custom forms. Jay
Re: [web2py] Making a field non-editable, but writable using SQLFORM
That doesn't seem to affect the HTML form output at all for me. I've also tried changing the widget to LABEL, but that results in the same problem with the value not being transmitted back via the form. What I'd like to be able to do is set the readonly attribute of the input tag; but I don't know how to do that in this context, where I cannot insert code between the creation on the SQLFORM and the accepts call.

Re: [web2py] Re: Making a field non-editable, but writable using SQLFORM
I'd been thinking I needed to do that between form creation and the
accepts call, but you're right, it works even after that point. I
make the call to auth.register, and then modify the readonly
attribute, and it works fine.
Thanks!

Jay, you can do:
form.element('#tablename_fieldname')['_readonly']=True

[web2py] Controller specific models
I've been unable to get my controller specific model to work in 1.96.4. Here's what I've got set up, can anyone point out the error? Controller: email.py, in app/controllers/email.py Model: email/settings.py in app/models/email/settings.py My understanding is that email/settings.py should be run for any page invoked in email.py. That isn't happening (verified with a print statement, just to make sure something else weird wasn't going on). Alternatively, if anyone has an example app that demonstrates using controller specific models, I can try running that to see if I've somehow broken web2py. Thanks, Jay
[web2py] Changing columns for TEXTAREA
I thought this might have gotten lost in the philosophical discussions
about line breaks, so figured I'd post it as a separate thread:
Using the advice given in a previous post, I'm doing this to try to
change the rows and columns for a TEXTAREA:
form=SQLFORM(db.contest,record=contest,submit_button=T(Save
Changes),fields=[name,description],_style='width:100%')
form.element('textarea')['_rows']=30
form.element('textarea')['_cols']=80
This works, in that the HTML output does have cols=80 and rows=30.
And the number of rows does change appropriately.
However, the number of columns displayed for the textarea does not
change, despite the HTML having the right value.
Is there something else that could be overriding the number of
columns? Something in Javascript perhaps?

[web2py] Two questions: one about markmin and one about SQLFORM
I've searched, but not found any information that helps me at my current level of web2py experience. Question 1: how do you insert a single line break (e.g. br/) in markmin? I've seen two spaces at the end of lines, but that doesn't seem to work for me. I've seen that you can use br as a separator instead of p, but that isn't what I want. I just want to put a single line break in specific spots in the content. Question 2: How can I alter the attributes of form elements using SLQFORM? Specifically, I want to change the number of rows and columns in a textarea, but I could see wanting to alter attributes of any form element. The answer is probably to create a custom widget for the field in the model, but I haven't been able to come up with anything that has any effect.
