Question

class MyTemplateAdmin(admin.ModelAdmin):
list_display = ('name')
search_fields = ['name']
inlines = [
    Template1Inline,
    Template2Inline,
    Template3Inline,
]

这很好用。但我需要的是让它充满活力。每当管理员向 MyTemplate 模型添加新模板时，都需要将其添加到内联中。

有办法做到这一点吗？如果我对我的问题不够清楚，请发表评论。提前谢谢！

Answer 1

我没有测试过这个，但理论上你可以这样做：

class MyTemplateAdmin(admin.ModelAdmin):
    def __init__(self, *args, **kwargs):
        super(MyTemplateAdmin, self).__init__(*args, **kwargs)
        #see if there are new templates
        #and set the inlines list property

    list_display = ('name')
    search_fields = ['name']

希望能帮到你。

Answer 2

在模板的admin.py中：

class Template1Inline(admin.TabularInline)
  pass

class Template2Inline(admin.TabularInline)
  pass

然后在admin.py中为MyTemplateAdmin：

import sys, inspect, Templates.admin
class MyTemplateAdmin(admin.ModelAdmin):
  list_display = ('name')
  search_fields = ['name']

  def __init__(self, *args, **kwargs):
    inlines = [class_type[1] for class_type in inspect.getmembers(Templates.admin, inspect.isclass)]
    super(MyTemplateAdmin, self).__init__(*args, **kwargs)

Templates.admin可能不正确，具体取决于您的项目设置方式，但关键是您只需导入具有Template1Inline类的模块。

Answer 3

只是一个简单的想法。

from django.contrib import admin
from mymodule import signals

class MyModuleAdmin(admin.ModelAdmin):

    def add_view(self, *args, **kwargs):
        signals.my_dynamic_inline_hook_signal.send(
            sender = self, 
            inlines = self.inlines,
            args = args, 
            kwargs = kwargs
        )

Answer 4

我不完全确定这是你在找什么。您想要内联是同一模型的不同实例吗？动态创建内联的一种方法是使用type（）并将它们添加到get_inline_instances（）

中

-(RequestResult*)makeSyncJsonRequest{

    __block RequestResult *retResult = [[RequestResult alloc] init];
    __block BOOL block = YES;

    dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);

   dispatch_group_t group = dispatch_group_create();

   void (^resultBlock)(RequestResult*) = ^(RequestResult* result){
      if(!retResult.error)
          retResult = result;
      block = NO;
      dispatch_group_leave(group);
  };

  // Add a task to the group
 dispatch_group_async(group, queue, ^{
       // Some asynchronous work

       dispatch_group_enter(group);
       [self makeAsyncJsonRequestWithBlock:resultBlock];
 });

 // Do some other work while the tasks execute.
 // When you cannot make any more forward progress,
 // wait on the group to block the current thread.    
 dispatch_group_wait(group, DISPATCH_TIME_FOREVER);
 return retResult;
}

只需覆盖管理员的get_inline_instances.

def get_inline_instances(self, request, obj=None):
    _inlines = super().get_inline_instances(request, obj=None)
    custom_inline = YourDynamicInline(self.model, self.admin_site)
    _inlines.append(custom_inline)
    return _inlines
