Django admin：按URL传递变量 [英] Django admin: pass variable by URL

问题描述

我想通过URL将变量传递给django管理员中的另一个页面。
它似乎不工作，我想传递变量/？name = hello，并通过request.GET.get [name，]来捕获它，但url变成/？ e = 1。
如果我使用默认参数'q'，它是有效的，但它会有冲突。
似乎这个问题只是django-admin。我需要通过url不要发布...
有谁知道如何解决这个问题

i want to pass a variable by URL to another page in django admin. it seems it is not working, i want to pass the variable "/?name=hello", and catch it by request.GET.get["name",""].but the url becomes "/?e=1" after it passed. if i use the default parameter'q', it works, but it will have a conflict. it seems this problem is django-admin only. and i need pass it by url not post... does any one knows how to solve this problem

谢谢

推荐答案

问题在于 name 不存在，当 get_query_set 尝试将其解析为模型字段。因此，一个 incorrectLookupParameters（）异常被引发，这反过来又重定向到不是很有帮助的e = 1url。 Django 1.4中引入了custom filterspecs，解决了这个问题。在此之前，一个可能的解决方案是动态地覆盖您的 ModelAdmins get_changelist返回的 ChangeList ）方法

The problem is that the lookup name does not exist when the get_query_set tries to resolve it as a model field. Thus an IncorrectLookupParameters() exception is raised which in turn redirects to the not very helpful "e=1" url. This problem is solved in Django 1.4 with the introduction of custom filterspecs. Until then one possible solution is to dynamically overwrite the ChangeList class returned by your ModelAdmins get_changelist() method.

此解决方案适用于Django 1.3：

This solution works on Django 1.3:

class MyModelAdmin(ModelAdmin):

    def get_changelist(self, request, **kwargs):
        changelist_class = super(MyModelAdmin, self).get_changelist(request, 
                                                                 **kwargs)

        class CustomChangeList(changelist_class):
            def __init__(self, request, *args, **kwargs):
                self._name = request.GET.get('name')
                super(CustomChangeList, self).__init__(request, *args, **kwargs)

            def get_query_set(self, *args, **kwargs):
                if self._name:
                    del self.params['name']

                qs = super(CustomChangeList, self).get_query_set(*args, **kwargs)

                if self._name:
                    return qs.filter([FILTER WHAT YOU WANT HERE...])

                return qs


        return CustomChangeList
