[web2py] Streaming a file
I need to place a button which opens an online PDF and so far I have this
in reg.py controller
def streamable():
data = urllib2.urlopen("http://www.pdf995.com/samples/pdf.pdf";)
return response.stream(data, 4096)
And this in the view
{{=A('open file', _class="btn btn-sm", _href=URL('reg', 'streamable'))}}
Although this only gives me stream output so a bunch of characters and not
actual pdf, anyone knows how to fix this?
Thank you!

[web2py] Calling a controller function from the view
Hello!
I need to call controller function from a jquery script in view and store
the returned dict into some variable. Looks something like this:
controller.py
def my_function():
return dict()
my_view.html
jQuery(document).ready(function(){
var my_dict = ...
});
Any help appreciated, thanks!

[web2py] Re: Calling a controller function from the view
EDIT:
I found something like this
controller.py
def my_function():
my_dict = dict()
return response.render('my_view.html, my_dict)
my_view.html
jQuery(document).ready(function(){
ajax('{{=URL('my_function')}}',[],'f2');
});
Although this just basically put my entire page into the f2 div and
inserted no dict... Where did I go wrong?

[web2py] Change value of select
I need to change selected option in the view, I know that to change input
value I do it like this: {{form.element('input', _name='field')['_value'] =
"new_value"}}, but how do I do this with select? Also, this needs to be
done in view, not controller so I cannot use default='some_option'.
Any ideas? Thanks!

[web2py] Login 'remember me' not working
Hello, I'm trying to add remember_me option to my auth login form and so
far it looks like this:
controller.py
def index():
auth.settings.remember_me_form=True
auth.settings.long_expiration = 3600*24*30
form = auth()
return dict(form=form)
view.html
{{=form.custom.begin}}
{{=form.custom.widget.email}}
{{=form.custom.widget.password}}
{{=form.custom.widget.remember_me}}
{{=form.custom.widget.submit}}
{{=form.custom.end}}
It doesn't display the remember_me option nor remembers anything, anyone
knows where the problem is?

[web2py] Re: Login 'remember me' not working
Apparently some other code I had in controller was breaking functionality
of this, now I reached the point when it actually displays the remember
button, although upon successful login and log out it doesn't actually
remember my info and nothing gets filled into the login form.

[web2py] Dynamically changing requirement of field in form
Hello.
I have a form in web2py that controls editing and adding new user. But some
fields need different requirements based on when user is being added or
edited. Can I somehow change field requirements in view? I can only detect
this in view. So far I came up with something like this, but it does not
work.
{{userform.custom.widget.name['requires'] = IS_EMAIL(error_message='invalid
email!')}}
Any ideas? Thanks for help.

[web2py] Select returns non existent fields
Hello, I have a problem with select.. I have these tables defined:
db.define_table(
'email',
Field('recipient', 'string', notnull=True),
Field('subject', 'string', length=256, notnull=False),
Field('body', 'text', notnull=False),
Field('html_body', 'text', notnull=False),
)
self.db.define_table(
'attachment',
Field('file_blob_id'),
Field('email_id', db.email, notnull=False)
)
When I insert something into email table and make select like
db(db.email).slelect(), it returns something like this:
, 'id': 27L}>
Why is there the attachment field? How do I remove it to just select real
fields and not relations with other tables? Thank you.

[web2py] Scheduler not creating its tables
Hello, I am trying to use scheduler for the first time in my app and I
cannot get it to work. Tables for scheduler are never really created. This
is my model scheduler.py:
from gluon.scheduler import Scheduler
from gluon import current
scheduler = Scheduler(
storage.mailer_db,
tasks={'send_email': Sender(db).send()},
utc_time=True)
current.scheduler = scheduler
Now, when I get to schedule a task like this
scheduler.queue_task(
'send_email',
pvars={'queue_id': some_id},
start_time=datetime.datetime.utcnow(),
stop_time=datetime.datetime.utcnow() + datetime.timedelta(seconds=600),
application_name="app")
Noting really happens, also worth nothing when I try to start workers with
python web2py.py -K app
I get this error:
NameError: global name 'urllib' is not defined
Any idea on what I might be doing wrong? Thank you!

[web2py] Setting filename to a streamed file
Hello. I have a backend function that is supposed to stream a pdf file, but not instantly download it. It's being called like this .../function_to_create_pdf/323, where the number is some ID. I create a FPDF stream and make function return this response.headers['Content-Type'] = None return response.stream(pdf_stream, 4096, filename="iwanthisname.pdf") Soo the problem is, this works well if I set attachment=True, but since I only want to display this pdf file, the filename is not applied in any way. I get the right document and all that, but the browser tab title is basically just the argument (ID) I passed to the function and if I press the download button it is saved as 323.pdf. I want to edit its name, how can I do this? I tried changing tab name with reponse.title, but it didn't work. Thank you. -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.
