django admin fieldsets - 添加相关模型的字段 [英] django admin fieldsets - adding fields of related models

问题描述

我有一个与 User 的OneToOne关系的模型 Employee 。我正在尝试在员工管理员中添加一些用户字段（ first_name，last_name，username，email ），以便直接从员工添加/更改窗体中编辑这些字段，但我还没有想出如何做到这一点。

我看到另一个时间以类似的方式做这种事情，但现在我有一个字段集错误：

为Employee指定的未知字段（first_name）。检查类EmployeeAdmin的字段/ fieldsets / exclude属性

这里是代码：

 ＃FIELDSETS 
 default_employee_fieldset =（
（'General'，{
'fields'：（
（'user'，'full_name' ，），
），
}），
＃..OTHER字段不包括
）
 
 finance_fields_employee_fieldset = [
 '，{
'fields'：（
（'full_name'，），
（'first_name'，'last_name'）

＃..没有包含

 self.fields ['last_name'] = forms.CharField（_（'last name'），max_length = 30，blank = True）
 
如果在kwargs中的instance：
 user = kwargs ['instance']。user 
 self.fields ['first_name']。initial = user.first_name 
 self.fields ['last_name' ] .initial = user.last_name

解决方案

管理员找不到user_name的原因是在类级别上没有在您的自定义表单上定义user_name字段。它仅在 __ init __ 中定义。当管理员检查可用字段的表单时，它只能访问类，而不是初始化的表单。所以检查表单类不会显示user_name可用。

直接在类级别定义所有字段，而不是窗体的 __ init __ 方法。如果您不需要所有情况的所有字段，则根据需要从 __ init __ 方法中的表单的字段字典中根据需要删除字段。

您也可以按照相反的方向执行此操作 - 将员工信息添加到用户编辑页面？这可以按照 https ：//docs.djangoproject.com/en/1.4/topics/auth/#adding-userprofile-fields-to-the-admin 。

最后，似乎你正在到达可能更容易实现所需功能的阶段，而不使用管理员 - 而Django的管理员确实有很多可扩展性功能，在某些时候编写自己的实现将比使用Admin更容易。 p>

I have a model Employee with a OneToOne relationship with User. I'm trying to include in the Employee admin some User fields (first_name, last_name, username, email), in order to edit those fields directly from the Employee Add/Change form, but I still haven't figured out how to do it.

I see another time do this kind of thing in a similar way, but now I have a fieldset error:

Any help on this?

解决方案

The reason Admin doesn't find user_name is that the user_name field isn't defined on your custom form at class level. It is only defined in __init__. When the admin inspects the form for available fields it has access only to the class, not an initialized form. So inspecting the form class doesn't show that user_name is available.

Define all the fields directly on class level instead of the form's __init__ method. If you don't need all the fields for all cases, then delete fields as needed from the form's fields dictionary in the __init__ method as needed.

You could maybe also do this in the reverse direction - adding Employee information to User edit page? This can be done as documented in https://docs.djangoproject.com/en/1.4/topics/auth/#adding-userprofile-fields-to-the-admin.

Finally, it seems you are reaching the stage where it might be easier to implement the features you want without using Admin - while Django's Admin does have a lot of extensibility features, at some point writing your own implementation will be easier than using Admin.
