django - PlaceholderAdmin throws () takes exactly 1 argument (2 given) -

I have written a plugin for django-cms, in which it has its own model with a placeholderfield. When I add a placeholder admin to the model administrator, I'm getting this admin on the site:

  Exception type: TemplateSyntaxError exception value: Error while rendering type: & lt; Lambda & gt; () Absolutely takes 1 argument 2 given) Exceptional location: & lt; Blablapath & gt; Presenting in /python2.6/site-packages/cms/forms/widgets.py, line 199    I'm looking for solution only with some problems with Django-cms example Which will run some paths in urls.py without any hesitation, so I think this may be a problem with the URL, especially when I do some magic in my URL. The question is, what terms should be there to be legitimate for the DJENGO-CMS URL? any idea? Any solutions? Anyone had this problem before?   
 
  This problem occurs when you enter  placeholder adminfield  Classes do not classify.  
 For example:  
  from cms.admin.placeholderadmin import placeholder import from placeholder cms.models.fieldsplaceholderfild class MyModel (models.Model): name = model. CharField (max_length = 100) sidebar = placeholder field ('sidebar') class MyAdmin (placeholder): "" "Put your general administrator content here. = ((None, 'field': ('name',),}), ('sidebar', '' square '': ('plug-holder', 'plug-holder-nopage'), 'field': ( 'Sidebar',)}),) Admin.site.register (MyModel, MyAdmin)

visual studio 2010 - How to reinstall MVC 2 tools for VS2010? -



    I uninstalled ASP.Net MVC 2 device for Visual Studio 2010. How can I restore it? MVC2 downloads seem to include only the VS2008 device.   Whatever I said, says that MVC 2 has been included in VS2010, but the installation of an improvement did not fix it, and MVC 2 is not listed. Add VS2010 / Select a component in the Remove screen.      You will get your VS2010ToolsMVC2.msi VS2010 DVD under WCU \ ASPNETMVC - hopefully it will do!    






Git Bash script to check whether repo has any commits? -



    I have a script on which I need to work differently if there is one, which is one or more , Commits. What is the best way to do this?   Something like this will appear in the proxy code.    #! / Bin / bash if [[`git log_count`] ==" 0 "]]; Then there is no commodity for this repo. # What goods ... and echo are "one or more committed!" # What are the other things?    Any ideas?      you can    git rev-parse -verify HEAD    (after :)     This is a pipeline command, and its behavior vs. "  git diff " There is very little possibility to change   I find it more pronounced  rev-parse -verify  means "is this a valid object name?"    This is your  show-ref .  You ask "Is there anything in this safe / head in the safe?"  I ask, "what current  head  exists?"   In practice, both of these are fair tests, because once you have a branch, so to achieve the  HEAD , some mock values will indicate manually lack of editing It is very diffic...
