[web2py] long running rpc call
Hi, We're making a number of rpc calls to other services using jsonrpc, and a few of them are particularly long running. I'd rather not use the scheduler, but instead was wondering if I could associate a jsonrpc httpclient in python to the current context so that longer tasks wouldn't block other incoming requests. I tried initially to just do a setattr on current (it's thread local storage as far as I understand), but that doesn't seem to work. Anyone have better ideas? Or am I just doing this completely wrong.

The issue is that a python list is returned, instead of a dict or just a string, therefore bypassing any of the generic views and auto-concatenating the list into a single string when accessed. Matt A list directly (see the code fragment below). Since generic.json serializes response._vars, it doesn't care about anything in env. You *could* write a view that accepts a dict with a list (or dict) as a well-known name and serialize that, but it's not what generic.json does.

The explanation isn't quite clear. I believe he's returning a list, intending that to be serialized as JSON. But web2py serializes anything that's not a dict as a string, so generic.json (for example) is never used. The question is: what should happen when a controller returns a list? The JSON serializer is happy to serialize a list. Is there any downside in doing it? Does it make any sense right now for a controller to return a list? Exactly. Apologies for lack of clarity.

I've tracked the issue down to gluon/main.py:231 where it checks if page is a dict, and what seems to be happening is that the valid json string above is instead being concatenated as a string representation. Adding this below the check for dict seems to fix it, but I'm not sure how well it fixes the problem: elif isinstance(page, list): response._vars = page run_view_in(response._view_**environment) page = response.body.getvalue() Any suggestions for other ways to go about fixing this?

There is surprisingly little information on the internet related to
these messages, but it seems (from a post on Cherokees forums) that
this indicates that the user is unable to access the /etc/shadow file.
I can verify that the nginx and uwsgi configurations are correct, and

Does anyone have a clue what's going on here? I'm getting to the point
that maybe web2py's pam auth module is the culprit, but I am very

[web2py] basic auth with custom get_or_create_user call
Hello, In our project we need to create a temporary user for the web2py app so that a remote system can send back a singe status update. In order to do this, when the command is sent out we create a temporary user like this: settings[serverUser] = str(uuid.uuid4()) settings[serverPassword] = str(uuid.uuid4()) user = auth.get_or_create_user(dict(username=settings[serverUser], password=settings[serverPassword])) This adds the user/password to the database just fine, however, login fails because of this line in login_bare: password = table_user[passfield].validate(password)[0] if I remove this line, the password is as expected, which leads me to think that we are not adding the password in the first case properly. Does it need to be hashed some way? Matt

Hmm I can't seem to get this working. I should probably have mentioned
that we are using basic auth to use this user on the client side. When
I hash the password and insert it into the database it is not hashing
the password passed in from basic login. Does this mean that we should
be changing the basic method to hash the password that it finds
there also? like this:
(username, password) = base64.b64decode(basic[6:]).split(':')
password = db.auth_user.password.validate(str(uuid.uuid4()))[0]
return self.login_bare(username, password)
Just to be clear, I'll reiterate what we're trying to do here.
A temporary user is created in the system with a uuid username and
uuid password like this:
settings[serverUser] = str(uuid.uuid4())
settings[serverPassword] =
db.auth_user.password.validate(str(uuid.uuid4()))[0]
user = auth.get_or_create_user(dict(username=settings[serverUser],
password=settings[serverPassword]))
then, on the client side, we are using curl to call a restful action
on the server using this login info, like this:
curl https://localhost:2345/some/rest/verb -u serverUser
from above:serverPassword from above
and its still redirecting. I can confirm that the passwords passed in
to login_bare are the same until this is called:
password = table_user[passfield].validate(password)[0]
settings[serverPassword] =
db.auth_user.password.validate(str(uuid.uuid4()))[0]

Aren't passwords always hashed when entered in the database? If so,
why aren't they hashed in the basic method before they are sent to
login_bare?

[web2py] basic authentication using pam

Re: [web2py] Re: login form errors
When I looked at how the generated sample app handled showing that there was an error with logging in, it showed the message in a flash area in the view. To be clear here: the controller is a two-liner: def user(): return dict(form=auth()) so there is no setup in the controller, as it relates to flash at least. This lead me to believe that whatever is going on in the creation of the auth form, it places errors into the session.flash variable, and I figured I could just add that to my view and the error would show up. This was not the case. What I'm really asking here is how to access that error information. It doesn't appear in session.flash, it doesn't appear in form.errors.

When an invalid username/password is entered the page simply reloads without any indication of what the error was. I tried to display the flash (we are not currently using the session flash, so this had to be added to this page) and that has no info in it, I have also tried to display auth.login_form()'s errors, which do not exist either.

[web2py] access to extra template files
Hello, I am trying to dynamically load templates that I have stored in a subdirectory of one of my views. The structure looks like this: app/ views/ test/ index.html list.html edit.html add.html templates/ first.html second.html (I hope that formatting is preserved..) I have this set up because I want to show different profiles for each test item - this is a composition. For edit, this works just fine, in the template I use include to import the proper template based on the type of the member variable. The problem I face now, is that in add I want to have a select box that loads the proper template, but have no idea how to actually load this file from the browser-side (this seems the only solution, without having to reload the whole page with the proper template). Is there a way to reference these html files from the browser side? http://site/app/test/templates/first.html does not work, for instance. Matt
[web2py] serving a zip file
Hi, In our project, we are trying to provide the ability to download a dataset in a zipped format. We've been transitioning old code to use web2py, and while I've been able to serve files using web2py elsewhere (images, for instance), I can't quite figure out how to serve this particular file. Below is the code I've come up with. When I take out the code to zip the file, it serves perfectly. Does anyone have experience with this? filename = %s-backup % (time.strftime(%Y%m%d-%H%M)) raw_data = a bunch of data stream = cStringIO.StringIO() zip_file = zipfile.ZipFile(stream, w, zipfile.ZIP_DEFLATED, False) zip_file.writestr(filename, raw_data) response.headers['Content-Type'] = application/octet-stream response.headers['Content-Disposition'] = attachment; filename=%s%s.bin % (time.strftime(%Y%m%d-%H%M), filename) return response.stream(stream, request=request) Thanks, Matt

Re: [web2py] Re: checkbox input default value
I'm using the Field in a rather unconventional way - I just have a
number of Field objects in a class that I refer to as my model (its
not actually connected to any database), and I use the SQLFORM.factory
to generate the form. The actual Field entry in the form looks like
this:
AutoStart = Field('AutoStart', 'boolean',
label=T(info))
in the view I use it inside a custom form like so:
dd{{=form.custom.widget.AutoStart}}{{=form.custom.label.AutoStart}}/dd
the resulting HTML is:
ddinput class=boolean id=no_table_AutoStart name=AutoStart
type=checkbox value=oninfo/dd
pretty straight forward, but you can see that the value is somehow there.

[web2py] composite views
Good morning, I have a situation where I want to display composite views (a view for an object inside a view for its parent object). I have a class Connection that has a Profile associated with it. Profile can be one of a number of different subclasses (AProfile, BProfile, CProfile). I also have views associated for each of the profiles, within a template directory under the views/connection directory. The way I've tried to go about solving this is to make a view.html (associated with the view() method in the controller) as a base template with a block for profile_section inside of it. Then, in each of the profile templates, I extend view.html and then fill out the block for the profile. The problem I am now facing is how to properly route to the right template file from within the controller's view method. I know I could just create a new method in the controller for each profile type, but I'd rather not do that if possible. I also think that a simple redirect is not the right solution here. Can anyone advise as to the best way to do this? Or am I just on the wrong track with the whole extend idea? Thank you, Matt

Do you need the field's widget or it's represent (they're two different

{{=A.B.represent(your_value, optional_record)}}
Would be similar for the widget.

From what I read in the source, I determined that was how to do it.
However, when I try to call represent that way I'm getting an error
that the 'NoneType' object is not callable.
This is what I've got:
model:
class Test:
name = Field('name', 'string')
view:
{{=terminal.name.represent(test)}}

Hello,
Is there a way to specify a value for the representation of a Field
object? I have a class (lets call it A) with a Field object member
variable (lets call it B), in my view I call {{=A.B.represent}} in
order to display the default widget for this field. I would like to
fill that widget with a value as well, is that possible?

Ah, I see. Is there a way to leverage the representations defined in
SQLFORM.factory for this? SQLFORM.factory worked to a certain degree
for my needs, but it also did not give me much freedom to design the
view the way I wanted. Instead, I've ended up creating this model
with the fields that I want, and I'm placing them one by one in the
view. The actual widgets that were rendered by SQLFORM.factory were
just fine - so can I use those somehow?

You can use SQLFORM.factory and still have complete control over the form
layout/appearance --
see http://web2py.com/book/default/chapter/07#Custom-forms.
But if you want to access any of the SQLFORM widgets independently, they are
of the form SQLFORM.widgets.[field type].widget --
see http://web2py.com/book/default/chapter/07#Widgets.

Somehow I completely missed this! Many apologies. Still, using this
approach I am still unclear as to how I might fill those widgets
when I'm using the SQLFORM custom form method. Ideally, I would fill
the form from the controller before display. I've tried:
- form.vars.var = value
- form.custom.var.widget.value = value
Neither of which work. Is this possible?

Re: [web2py] Re: xmlrpc backend
I think I will end up just writing my own model for this (a la Anthony's suggestion), but the problem remains that model as it relates to web2py presumes SQL, and that fact limits design. While it would be possible to write an XMLRPC adapter to the DAL, that is sort of like jamming a square piece into a triangle hole - more than not you'll probably end up wishing you just used the direct database connection! I think the long term solution to this problem is to decouple the data models from database access.

So for the fourth time: We could add an XMLRPC adapter to the DAL that instead of making SQL calls, could build an XML version of the query that could be passed on to another web2py app via xmlrpc. That app could then return the results as XML, which is then converted back to Row objects and returned to the application, making XMLRPC remote database access completely transparent and make things like SQLFORM.grid work. The only problem I see (aside from there being a lot of work to do) would be security. We would have to make web2py apps acts as a db service, like it does with CAS, and restrict who can access the XMLRPC-DB service. But this would be VERY cool and extremely helpful in building scalable (multi-tier) apps. I would be interested in helping to write code to make this happen.
