Minimal layer setup for Zope3
Project description
This package provides a minimal layer setup for Zope3.
Minimal Browser Layer for Zope 3
This package contains the minimal layer. This layer supports a correct set of component registration and can be used for inheritation in custom skins.
Right now the default implementation in Zope3 has different restriction in the traversal concept and use to much registration on the default layer.
IMinimalBrowserLayer Interface
The minimal layer is useful for build custom presentation skins without access to ZMI menus like zmi_views etc. This means there is no menu item registred if you use this layer.
This layer is NOT derived from IDefaultBrowserLayer. Therefore it provides only a minimal set of the most important public views such as @@absolute_url. The following packages are accounted:
zope.app.http.exception
zope.app.publication
zope.app.publisher.browser
zope.app.traversing
zope.app.traversing.browser
Testing
For testing the IMinimalBrowserLayer layer we use the testing skin defined in the tests package which uses the IMinimalBrowserLayer layer as the only base layer. This means, that our testing skin provides only the views defined in the minimal package and it’s testing views defined in tests.
Login as manager first:
>>> from zope.testbrowser.testing import Browser
>>> manager = Browser()
>>> manager.addHeader('Authorization', 'Basic mgr:mgrpw')
Check if we can access the page.html view which is registred in the ftesting.zcml file with our skin:
>>> manager = Browser() >>> manager.addHeader('Authorization', 'Basic mgr:mgrpw') >>> skinURL = 'http://localhost/++skin++MinimalTesting' >>> manager.open(skinURL + '/page.html') >>> manager.url 'http://localhost/++skin++MinimalTesting/page.html'>>> print manager.contents <BLANKLINE> <html> <head> <title>testing</title> </head> <body> <BLANKLINE> test page <BLANKLINE> </body> </html> <BLANKLINE> <BLANKLINE>
Now check the not found page which is a exception view on the exception zope.publisher.interfaces.INotFound:
>>> manager.open(skinURL + '/foobar.html') Traceback (most recent call last): ... HTTPError: HTTP Error 404: Not Found>>> print manager.contents <BLANKLINE> <html> <head> <title>testing</title> </head> <body> <div> <br /> <br /> <h3> The page you are trying to access is not available </h3> <br /> <b> Please try the following: </b> <br /> <ol> <li> Make sure that the Web site address is spelled correctly. </li> <li> <a href="javascript:history.back(1);"> Go back and try another URL. </a> </li> </ol> </div> </body> </html> <BLANKLINE> <BLANKLINE>
And check the user error page which is a view registred for zope.exceptions.interfaces.IUserError exceptions:
>>> manager.open(skinURL + '/@@usererror.html') >>> print manager.contents <BLANKLINE> <html> <head> <title>testing</title> </head> <body> <div> <div>simply user error</div> </div> </body> </html> <BLANKLINE> <BLANKLINE>
And check error view registred for zope.interface.common.interfaces.IException:
>>> manager.open(skinURL + '/@@systemerror.html')
>>> print manager.contents
<BLANKLINE>
<html>
<head>
<title>testing</title>
</head>
<body>
<div>
<br />
<br />
<h3>A system error occurred</h3>
<br />
<b>Please contact the administrator.</b>
<a href="javascript:history.back(1);">
Go back and try another URL.
</a>
</div>
</body>
</html>
<BLANKLINE>
<BLANKLINE>
And check the zope.security.interfaces.IUnauthorized view, use a new unregistred user (test browser) for this:
>>> unauthorized = Browser() >>> unauthorized.open(skinURL + '/@@forbidden.html') Traceback (most recent call last): ... HTTPError: HTTP Error 401: Unauthorized>>> print unauthorized.contents <BLANKLINE> <html> <head> <title>testing</title> </head> <body> <div> <BLANKLINE> <h1>Unauthorized</h1> <BLANKLINE> <p>You are not authorized</p> <BLANKLINE> </div> </body> </html> <BLANKLINE> <BLANKLINE>
CHANGES
1.2.0 (2009-02-21)
Security issue: The traverser defined for IMinimalBrowserLayer was a trusted adapter, so the security proxy got removed from each traversed object. Thus all sub-objects were publically accessable, too.
1.1.0 (2009-02-19)
Fixed dependency warning about ISite.
Fixed tests to work with newer zope.testbrowser.
Using zope.container instead of zope.app.container.
Made sure that long_description renders properly on pypi.
1.0.1 (2008-01-24)
Bug: Improved meta-data.
1.0.0 (2008-01-21)
Restructure: Move z3c.layer.minimal package to it’s own top level package from z3c.layer to z3c.layer.minimal.
0.2.3 (2007-11-07)
Forward-Bug: Due to a bug in mechanize, the testbrowser throws httperror_seek_wrapper instead of HTTPError errors. Thanks to RE normalizers, the code will now work whether the bug is fixed or not in mechanize.
0.2.2 (2007-10-31)
Bug: Fixed package meta-data.
Bug: Fixed test failures due to depency updates.
Restructure: Fixed deprecation warninf for ZopeSecurityPolicy.
0.2.1 (2007-??-??)
