How to get all the menus of a user through program?

[Velu Narasimman]

Hi,

    I am using MenusPlugin for displaying submenus. I need to get all the menus that are about to be displayed for a user even before he logs into the site.  Is it possible? If yes, how shall I do it in a back-end program? Please share me your ideas.

    Thanks in advance.

Well, I am getting menu as a dictionary as shown below,

{'mainnav': [{'active': False, 'name': 'project', 'label': <Element "a">}, {'active': False, 'name': 'added_common', 'label': <Element "a">}, {'active': False, 'name': 'admin', 'label': <Element "a">}, {'active': False, 'name': 'reports', 'label': <Element "a">}, {'active': False, 'name': 'metrics', 'label': <Element "a">}, {'active': False, 'name': 'mytimesheet', 'label': <Element "a">}, {'active': True, 'name': 'myprojects', 'label': <Element "a">}, {'active': False, 'name': 'timesheetapproval', 'label': <Element "a">}], 'metanav': [{'active': False, 'name': 'login', 'label': u'logged in as karthikeyan.nagaraja'}, {'active': False, 'name': 'logout', 'label': <Element "a">}, {'active': False, 'name': 'prefs', 'label': <Element "a">}, {'active': False, 'name': 'about', 'label': <Element "a">}]}

I get this, when I refresh the web page in my browser. These menus are dynamic, differs among different users based on the permissions that they have in system. But I wish to generate this without using a browser. So how can I make a web request handling in program itself and the above menus?

So you know about XML-RPC-Plugin [1]?

IMHO this is the most standardized non-browser access to enabled Trac sites.

Are you calling Chrome.get_navigation_items?

https://trac.edgewall.org/browser/tags/trac-1.4/trac/web/chrome.py#L862

You'll need to make a MockRequest. For examples, I believe this is done in a few plugins, but I don't recall which off-hand.

I suppose you could use MockRequest from the test module:

https://trac.edgewall.org/browser/tags/trac-1.4/trac/test.py#L151

Or better might be to extract and modify this code to meet your needs:

https://trac.edgewall.org/browser/tags/trac-1.4/trac/web/chrome.py?marks=947-952#L947

With regard to the mock Request object, navigation contributors only check permissions like "PERM in req.perm", so your mock could just return True for that case.

I want to achieve this without making a HTTP request from browser. I guess the chrome.get_navigation_items will work only if there is a web request. Isn't it? Otherwise, I wish to make it without authenticating/bypassing authentication and everything within a python script file. Is this possible? Please share me your ideas.

Yes, you can use from Python. The samples shown are part of the Trac API. You'll need to Mock out the Request object.
