Re: [pylons-discuss] Dynamically-generated PDF to download

does this is:

I want to add a view that returns a FileResponse, as rendered by the print
media, so that particular location results in a download of that PDF, but I
don't want to repeat code.
I don't want to serve a static asset, I want the PDF to be dynamically
created.
Any ideas on how to tackle this best?
Here is an example:
https://github.com/wichert/checking/blob/master/src/checking/invoice.py#L306
https://github.com/wichert/checking/blob/master/src/checking/invoice.py#L306
The basic approach is: generate your data (in this case the PDF file), create a
response object using your data, set the right headers for it and return it
from your view.

Hello Everyone,
Is there a way I can handle HTTP OPTIONS request in pyramid? I am trying to
make a CORS request with a custom header hence it's preflighted and I want to
handle the HTTP OPTIONS request. Any kind of help is appreciated. Thank you.
Handling OPTIONS is no different than handling any other request method as fast
as Pyramid is concerned. The simplest way to do that is to specify the
request_method parameter for the view_config decorator:
@view_config(route_name=‘my-route’, request_method=‘OPTIONS’,
renderer=’string'):
def my_route_options(context, request):
request.response.headers.update({
‘Access-Control-Allow-Methods’: ‘POST,GET,OPTIONS’,
‘Access-Control-Allow-Credentials’: ‘true’})
return ''
If you are writing a REST backend you may also want to look at rest-toolkit
(see http://rest-toolkit.readthedocs.org/en/latest/
http://rest-toolkit.readthedocs.org/en/latest/ ) which will automatically
handle OPTIONS for you.

Oscar,
It's probably safer to pass the translated string as a template variable from
the view callable, since Pyramid's i18n machinery only picks up translation
strings marked via i18n:translate and i18n:attributes in .pt files IIRC.
Basically, you would pass products as a string marked for translation to
your template from the view.
The template would be the following (using your original code)...
pa href=/${request.locale_name}/${products}img src=products.jpg
alt= //a/p
While the view would mark the products string for i18n as follows...
from pyramid.i18n import TranslationString as _
...
@view_config(route_name='products', renderer='templates/products.pt
http://products.pt/')
def products_view():

Thanks Wichert. If I try what you say with nothing else, it doesn't work yet:

However, if I add at the top of the template the following statement, it
works as expected:
?python from pyramid.i18n import TranslationString as _ ?
Is this the way it should work?
It is! You can also use a BeforeRender event to expose _ to all templates. See

The exact response here will vary a bit depending on your authentication
policy. For auth_tkt you should see a couple of Set-Cookie headers that set the
authentication cookie. If you use a session authentication policy you might not
see anything here, or only a Set-Cookie header to set the session cookie.
print(unauthenticated_userid(request))
print(authenticated_userid(request))
Those function only work on an incoming request, not on a response object.
How can I test that authentication has worked?
That depends a bit on your testing style. The most reliable method is to write
an integration test and do a second request and check the response to see if
authentication succeeded. The pure unit-test approach is to insert a mock for
remember() and check if the headers returned by remember() show up in the
response headers.

For example, maybe I'll set a cookie that shouldn't have been set because of the cookie's path attribute, expiry time, or something else I didn't consider (but a browser or proper web client would). request1 = DummyRequest(post=) response1 = views.login(request1) # What's the least error-prone way of turning all the Set-Cookie's from response1 into Cookie's in request2? request2 = DummyRequest(post=.) response2 = views.someotherview(request2) I took a look at the Integration testing and Functional testing sections at http://docs.pylonsproject.org/docs/pyramid/en/latest/narr/testing.html but they don't mention such a workflow.

You can use Lingua 2 with Pyramid 1.4 as well. I would still use Babel for its l10n features (CLDR access) so you get date, time, currency, etc. formatting correct for all locales. One gotcha that tripped us up was that every template (including pyramid_layout panels) needs to have the i18n:domain attribute specified.

For what it's worth: that is by design. Your layout template, or any METAL macro you are calling, might come from a different source and use a different domain than the calling template. If the domain would be passed down when calling a METAL macro you could get very strange results in complex systems where you use multiple domains: depending on where you call a macro from you could get very different results. To guarantee that the i18n behavior is predictable the i18n domain is only managed through the local hierarchy in the template.

If someone picks “password” as username the results will be interesting. Worse things will happen if you other characters. For example what my password is “password@192.168.0.100/“ – will that make the system try to connect to a PostgreSQL server at 192.168.0.100?

You may need to explicitly dispose of the engine. I would recommend to look at
the pytest section of the pyramid_sqlalchemy documentation:
https://pyramid-sqlalchemy.readthedocs.org/en/latest/tests.html#py-test-fixtures
. That describes in detail how you can setup pytest fixtures for SQLAlchemy,
and use this with functional tests of a Pyramid application.

I think that you can translate your urls at generation time:
mapper('blog', '/{lang}/{slug}', controller=''...)
Then in templates/python code:
from pylons.i18n import get_lang
url('blog', lang=get_lang(), slug=_(slug_var))
(dont remember if get_lang() return a string or a list of all accepted
languages)
What I found to be simpler is to leverage some route tricks. I have a
route which looks like this:
map.connect(shop_category, /shop/:category,
controller=shop, action=category,
conditions=dict(function=translate_incoming),
_filter=translate_outgoing)
def translate_incoming(environ, match_dict):
# ... translate the URL data in matchdict to canonical language
def translate_outgoing(match_dict):
# ... translate the URL data in match_dict to target language
that will allow you to use one canonical language everywhere in your
code, and routes will call your two translation things when needed.

Zope also ships with DTML (which is much older than ZPT) which is possibly more similar and possibly more comparable to text-based templating languages. You seem to imply that attribute-style languages such as ZPT (or Genshi/kid/meld/etc.) have to be slower than text-based languages.

I was just playing with this and it seems that the genshi syntax is
somewhat limited. Is that correct?
For example, including a site page just like this example from gensh
blows up.
http://genshi.edgewall.org/wiki/GenshiTutorial#AddingaLayoutTemplate
And even though I know it's not good practice to do the whole?
python ? thing, chameleon seems to blow up on this as well.
To be more precise: chameleon.genshi implements the Genshi XML template
syntax as described in
http://genshi.edgewall.org/wiki/Documentation/0.5.x/xml-templates.html .
?python is not a part of that syntax.
That tutorial does not work due to a limitation chameleon.genshi
currently has: match templates defined in included templates are not
applied to the calling document. That is documented at
http://pypi.python.org/pypi/chameleon.genshi. If enough people ask
Malthe if he can add support for that might be fixed :)

What is the best way to get the output of the background process back to the user? Often the better way of doing this is to run a separate persistent long running process which has an XML-RPC interface and have the web application communicate with the back end process using XML-RPC. This avoids all the mess that can often occur with forking off a web application process. zc.async (see http://packages.python.org/zc.async/1.5.0/ ) might also be interesting.

Re: Plugin architecture
Previously Mike Orr wrote: The most difficult problem seems to be controllers, and the 'controller_scan' argument in Routes which seems useless. (We had to hardcode the controllers in our GUI BILS app because of some incompatibility with py2exe.) Several people have asked how to have controllers in various packages and then pull in a selection of them. The simplest method is stub modules in the controllers directory that import the actual controllers. But maybe we can find something more flexible. If you decide to use zope.component a controller could be a named utility. You could then register it like so: class BaseController(object): This is the standard Pylons base controller class. implements(IPylonsController) class MyController(BaseController): My very own controller. registerUtility(MyController, name=my_controller) and Pylons could get a list of all utilities using something like this: controllers = getUtilitiesFor(IPylonsController) This prevents the need to skin directories as currently happens, and will allow you to put your controllers anywhere you want. You can also selectively do the registerUtility calls, override already registered controllers or remove controller registrations.

The only change for a Pylons user is adding a single line to register the controller. The interface that is used to manage the registrations can be hidden in the BaseController class and internal pylons logic - people may never need to know about it. This gives you a lot of extra flexbility and pluggability, at the expense of asking people to add a single line of code for each controller.

category support for flash
Often it is very useful to have flash/status messages of several different types, for example to be able to differentiate between informational messages, warnings and errors. To do that I made a simple extension to WebHelpers to add category support to its Flash class.

Re: buildout vs virtualenv for pylons and/or other wsgi apps?
Previously Mike Orr wrote: On Sun, Dec 14, 2008 at 8:38 PM, Iain Duncan iaindun...@telus.net wrote: Hi folks, I totally do not want to start a flame war here, but was wondering if people could give me their reasons for preferring buildout or virtualenv for automated builds of pylons apps or other wsgi apps. Virtualenv is more popular because it follows traditional Python usage for the most part. You install packages interactively and can change your mind at any time. Buildout's configuration recipes are hard for many people to memorize, and it's more suited to situations where you know ahead of time exactly which libraries you'll need You can change the configuration and rebuild the environment from scratch, but it's not as easy as installing an experimental package, trying it out, and then uninstalling it if you don't like it.So with virtualenv you can use the same tools for development as you use for deployment, whereas buildout is more of a deployment-only thing. I do not fully agree with that: I use buildout for development all the time. One very very important thing buildout adds is repeatability. I can take my buildout and deploy it it any random other machine and be sure that I will have the exact same environment afterwards, down to exact package versions if needed. Adding more librares with buildout is just as simple as with virtualend, the pattern is just a bit different: instead of running easy_install you add declare the new dependency in setup.py and re-run buildout. This has the advantage of guaranteeing that your dependencies are declared correctly: buildout will happily install everything you need and uninstall everything you do not need to keep the system as clean as possible.

There's no reason you have to use FormEncode, AuthKit, or any of those other pieces unless you want to, and if you are beginner to Python or web development you might off avoiding those pieces and just writing your own ad hoc code. grok is much more pluggable than pylons and has more documentation available (especially if you also consider all zope documentation that works for grok apps as well).

Re: Pyjamas : Python - JS
Previously Eric Ongerth wrote: I have heard that the more you try to make Javascript behave like Python, the more you end up hating Javascript -- but that says nothing about Javascript itself. Javascript is really a different language, with different strengths. Perhaps the best plan is to use Javascript for its strongest points (for example instant-turnkey use of JSON, totally anonymous objects, function mutability, etc.) and do your more Pythonic tasks in Python. Pylons makes it quite easy to leave as much of your logic as you wish in your controllers and keep your client- side view code very very thin. Especially if you use a lightweight, concise JS framework like jQuery to help keep things readable and organized. That still leaves the case of the programmer who says, I want to keep as much logic as possible on the client side to ease my server load, but I hate Javascript. In that case I don't have any good advice. Choose a new carreer :) The claim that Javascript become[s] quickly unreadable for even medium-sized applications really reflects only on the individual programmer/developer and not on the language, honestly. Javascript does not deserve to be compared to (e.g.) php, an unruly beast that literally encourages a mess. Javascript is, at worst, neutral with respect to organization; at best it embodies the heights of abstraction, encapsulation, and readability. It's all up to you. A problem with javascript is that most people using it never get beyond writing tiny bits of code to perform a single effect on a page. With new frameworks making that even simpler that is even more true now than it was a few years ago. But once you get beyond that you will indeed see that javascript is a very nice and fun language.

Beaker seems to be very little documentation online, so hopefully someone can help me out here. I am looking at caching the results of things like expensive function calls and database queries, and beaker seems to be usable as a caching system. What I can't seem to find is how to conveniently handle per-request and forever-lasting caching. In Zope I can do this: from plone.memoize import forever from plone.memoize import view @forever.memoize def expensive_stuff(): The result of this function is cached forever, with the function and its argument as cache keys. @view.memoize def expensive_stuff(): The result of this function is cached during this request only, with the function and its argument as cache keys. as far as I can see there is no direct alternative for beaker, is that correct?

No, paste relies on it to handle entry points in various places. That is a very popular pattern that more and more things are starting to use. Popular, but it's still on unstable ground because Setuptools isn't built into Python yet,. This is just one of a series of problems people have when installing Pylons. It's worth remembering that there aren't many packages that depend on others, much less a multilevel dependency -- Pylons and TurboGears are about it. The zope libraries are much larger and have much more (too many) dependencies than Pylons and Turbogears, by several factors. Unfortunately that puts the onus on us to either fix the Setuptools problems ourselves, complain to the developers, or make Pylons/Paste less dependent on Setuptools. What exactly are 'the setuptools problems'? Entry points and namespaces are very practical and I wouldn't want to loose them. All the installation and index-handling logic in setuptools is probably best replaced. The whole idea of importing an application by entry point when you already know what the module is called and it's already been installed is kind of funny. But in this case, the problem seems to be not entry points or namespace packages but pkg_resources.require. The purpose of pkg_resources.require, according to its documentation, is to guarantee version dependencies are satisfied and to activate eggs that are along sys.path but not on it. I tend to think this whole concept is obsolete now that you can install different versions into different virtual environments. I don't know of anybody who has installed multiple versions of a package into the same directory, and then had two applications that each used pkg_resources.require to activate a different version. On the other hand, I know people who have hesitated to use pkg_resources.require because that makes the application or library depend on Setuptools. I've never used multi-version support or resources.require, and I agree that we have better tools now. I think a problem of setuptools is that it does too many things, and not all of them very well: - namespace handling - entry points - multi-version egg installation - building and uploading eggs - egg installation - remote package searching and downloading pyinstall already does a better job at the last two. A simple implementation of the first two in the standard library would go a long way to improving things.
