pyramid

I managed to make a Pyramid 1.2 WSGI app run on Google App Engine SDK 1.7. However, my current project uses several new Pyramid 1.3 features and I'm stuck on a WebOb version issue. Here's the error message: VersionConflict: (WebOb 1.1.1 (/home/matt/Python/google_appengine/lib/webob_1_1_1), Requirement.parse('WebOb>=1.2dev') Is there something I can do or I must wait for a new GAE release? A fairly reliable way to manage your pyramid application and it's dependencies on appengine is via the pyramid_appengine library which generates a skeleton project that uses buildout . disclaimer: I wrote

I have some experience with different web frameworks (Django, web.py, Pyramid and CherryPy), and I'm wondering in which one will it be easier and hopefully cleaner to implement a route dispatcher to a different "view/handler" based on the "Accept" header and the HTTP method e.g.: Accept: application/json POST /post/ is handled different than: Accept: text/html POST /post/ So the request gets routed to the particular view of the corresponding handler of the MIME "application/json" and the HTTP method "POST". I do know how to implement something like that in CherryPy, but I lose the use of the

I'm having some problems using SQLAlchemy in Pyramid. Although I can find examples of what I need, they're normally very short and lacking. So I've ended up with patchy code that barely makes any sense. So I'm hoping someone could give a fuller example of what I need to do. I have 4 databases all with the same schema. I want to be able to work on them from one Pyramid app, sometimes listing all "orders" from all 4 databases, sometimes just listing all "orders" from "site1". As the schemas are the same, I also use the same model classes for the databases. I've tried it with both sqlahelper and

I have a simple root resource factory: class Root: __acl__ = [ (Allow, Authenticated, 'edit') ] Now for some "special" routes, I need to create another resource factory config.add_route('special', '/special/test', factory=SpecialFactory) class SpecialFactory: __acl__ = [ (Allow, Authenticated, 'special_edit') ] Now, I want to make Root the parent of SpecialFactory -- how should I do it? Is this the right way... class SpecialFactory: def __init__(self, request): self.request = request self.__parent__ = Root(request) self.__name__ = 'special' __acl__ = [ (Allow, Authenticated, 'special_edit') ]

I am using sqlite database and I declared the models as in this gist https://gist.github.com/mmahesh/7245561 I have added a model instance with transaction manager as with transaction.manager: model = Users(username='example',name='Example', email_primary='m@m.com', _password='example') DBSession.add(model) Whenever I execute initialize_sample_db development.ini, this error shows up sqlalchemy.exc.IntegrityError: (IntegrityError) constraint failed 'INSERT INTO users (name, username, email_primary, email_secondary, _password, bio) VALUES (?, ?, ?, ?, ?, ?)' ('Example', 'example', 'm@m.com',

How should I do a while ( x < y ) in jinja2? I've seen the jinja2 docs, it seems like they only support for loop for a declared variable of array and while() is not supported at all. I think your closest alternative with Jinja2 would be to use a for with range : {% range number from 3 to 6 %} {{ number }} (...) {% endrange %} And you can pass the variables from your program to use them in the loop. 来源： https://stackoverflow.com/questions/13668025/how-to-do-a-while-x-y-in-jinja2

Trying to upload multiple files at once using python. The upload.html source code is as followed: <form name="frmRegister" method="post" accept-charset="utf-8" enctype="multipart/form-data" class="form-horizontal"> <div class="control-group"> <div class="controls"> <input type="file" name="files" multiple='multiple'> </div> </div> <div class="control-group"> <div class="controls"> <input class="btn btn-primary" type="submit" name="btnSubmit" value="Add Product" /> </div> </div> </form> in my admin.py: @view_config(context="mycart:resources.Product", name="add", renderer='admin/mall/product/add

I'm trying to implement Pyramid's Security features in my website but I'm having some trouble figuring out how to use it. I've been reading over this tutorial and this example , as well as the Pyramid docs, and I can't figure out how to implement an authorization policy for single page IDs. For example, I have the following URL scheme: /pages /pages/12 /pages obviously lists the available pages and /pages/:id is where you can read/comment on the page. The documentation/examples I've read have shown that you can implement group level ACS's by providing a groupfinder callback with a list of

I'm quite new to Python. I've downloaded the Pyramid Framework and have been trying to understand it. It uses many separate tools for its work. For example some PasteDeploy . I tried to read PasteDeploy 's manual but can't understand anything. There is almost no valuable examples and explanation. Just syntax. All I understood is that it uses .egg format everywhere. It is based on .egg format: [composite:main] use = egg:Paste#urlmap [app:home] use = egg:Paste#static [app:blogapp] use = egg:BlogApp At the same time I found that .egg format is going to be thrown away from Python's package's
