python - Permissions for a site only -

-

I have a multilingual Django project. Every language is a separate subdomain so we use the "site" application and Have decided to create a separate site for.

On that project, I also have a "page" application, which is similar to CMS. Users can create pages containing content and they will appear on the appropriate language site.

I am now looking to be able to manage advanced permissions. What I need to do is, in the Admin app, a user only allows to create and update pages for one (or more) specific language / site.

What would be the cleaner to do something like this

Edit: Chris I

, I am making a decorator who checks whether the user is appropriate for the user or not the group who is reaching Lang, Chris accepts the answer for this example. In the "normal" view, I do the following: 

  def view (self): # if you want to return Return_to_presson ('Page1', {} , See requestcontent (request)) = group_require (see)

If the user is in the group, then that method will return, otherwise it will return a "login denied" error.

And in my admin, I do the following: 

  class PageAdmin (admin.ModelAdmin): list_display = ('title', 'published') field = [( None, {'field': ['title', 'slug', 'whatever_field_use_heave']}), DEF is_ad_promotion (auto, request): return_group_required (requested) Admin.site.register (page, pageadmin) < / Code>

where in_group_required is similarly the group_required method described above but if we have access or not, then only true or false return on the basis of its basis Will come

And because we use them very much in the previous examples, you will tell here what I have in my group and group-wise methods 

  def group_required ( Return_decorator def in_group (request): language (func): def _decorator (request, * args, ** kwargs): if not in_group (request): return HttpResponse ("login denied") return func (* args, ** kwargs) Language.objects.get (site__domain__exact = request.get_host ()) for group in group.group.all (): if request.user () in group.user_set.all: return correct return incorrect

You add per group / group of languages ​​and groups accordingly.

Then, you can check whether the request.user.groups belongs to the group. (You can do this with the decorator: 

  def group_required (func): def _decorator (request, * args, ** kwargs): hostname = request.META.get ('HTTP_HOST' ) Lang = hostname.split (".") [0] If request.user.groups do not have a gender: return HttpResponse ("Access denied") return func (* args, ** kwargs) _decorator  < / Pre> 
 (Correct / Modify the code according to your needs ...)

MySql variables and php -

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

url rewriting - How to implement the returnurl like SO in PHP? -

-
This URL should work even after the rewrite. Is this possible? Otherwise, I can only hardcoded everything If you are trying to create a login system with redirection You need to use the HTTP_REFERER header to find out where the user came from so that you can send it back there. The best way to do this is to use something like this in your login form: // - Login php & Lt; Input type = "password" name = "password" /> & Lt; Input type = "hidden" name = "returnrelale" value = "& lt ;? php echo $ redirectURL ;? & gt;" / & Gt; & Lt; / Form & gt; Please note that some ISP, browser or proxy will delete the referrer header, so you can not rely on each user to work fully. If you use a statement, to check whether the header exists or not, you can send those users back to the homepage or whatever. Edit If you are looking to use $ _SERVER ['REQUEST_URI'], if you are running Apache It sho...

kernel - How to create a "Block device" in Windows -

-
For people familiar with Linux, it is possible to create a module and register it as a block device. This allows the user to mount it as a regular disk (whereas all block I / O is controlled by the module, for example USB-MastStorage). Is there a way to do this in windows? (Windows needs to create a volume. Raw data will come from the interface with justification.) Thanks The easiest way (and this is not easy!) Is to write one, you can do it also with KMDF. The latest issue of the "NT Insider" of the OSR is an article in how to do this, but it not is going to be easy anyway You will learn a ton, though, So if you are interested in kernel development, then this is a good way to start!
