在渲染之前将表单'author'字段设置为登录用户 [英] Set form 'author' field to logged in user before render

问题描述

我想将我的表单作者字段（models.ForeignKey（User））的默认值设置为当前登录的用户。我想在保存条目之前做到这一点，所以当创建一个条目时，用户不必选择自己才能验证表单。

I want to set the default value of my forms 'author' field (models.ForeignKey(User)) to the currently logged in user. I want to do this before the entry is saved so when creating an entry the user does not have to select themselves in order for the form to validate.

我尝试在我的表单init函数中设置值，但是没有引用请求对象，所以似乎不可能？

I tried setting the value in my form init function, but there is not reference to the request object so it seems impossible?

我没有在这个应用程序中使用django管理面板。

I am not using the django admin panel for this application.

推荐答案

动态初始值适用于我，默认情况下为 Django表单视图：

Dynamic initial values worked for me, for a default Django form view:

if request.method == 'POST': 
    form = ContactForm(request.POST) 
    if form.is_valid(): # All validation rules pass
        # Process the data in form.cleaned_data
        return HttpResponseRedirect('/thanks/') # Redirect after POST
else:
    form = ContactForm(initial={'author': request.user }) 

return render_to_response('contact.html', {
    'form': form,

这将为作者下拉菜单设置未绑定表单的初始值，用户在编辑时仍然可以改变它。

This sets the initial value in the author drop-down for an unbound form, the user could still change it whilst editing.
