我有一个事件模型:
class Event < ActiveRecord::Base
belongs_to :author, class_name: 'User'
end
我可以输入控制台:
e=Event.last
e.author
在rails_admin中创建新事件时,我不想在表单中显示author_id字段。我想在控制器中设置这样的东西:
@e=Event.new(params)
@e.author_id=current_user.id
@e.save
可以在rails_admin中执行吗?
我在官方维基中找到了这个document,但是我不想使用cancan能力而且我不想在author_id字段中设置一个隐藏字段,因为这样会很危险安全性,事实上POST请求可以使用自定义author_id覆盖。 我想简单地在控制器中分配author_id。 有可能吗?

我没有找到干净的方法在rails_admin中执行此操作。这是一个未解决的问题:https://github.com/sferik/rails_admin/issues/1855。
这可能不是最佳选择,但您可以在create action中覆盖全局逻辑。看看它是如何工作的:https://github.com/sferik/rails_admin/blob/master/lib/rails_admin/config/actions/new.rb。
有一个register_instance_option :controller
块。这意味着您可以通过配置传递此选项。更多信息:https://github.com/sferik/rails_admin/wiki/Actions。
因此,如果您真的需要它,可以编辑/config/initializers/rails_admin.rb
:
RailsAdmin.config do |config|
config.actions do
dashboard # mandatory
index # mandatory
new do
controller do
proc do
if request.get? # NEW
@object = @abstract_model.new
@authorization_adapter && @authorization_adapter.attributes_for(:new, @abstract_model).each do |name, value|
@object.send("#{name}=", value)
end
if object_params = params[@abstract_model.to_param]
@object.set_attributes(@object.attributes.merge(object_params))
end
respond_to do |format|
format.html { render @action.template_name }
format.js { render @action.template_name, layout: false }
end
elsif request.post? # CREATE
@modified_assoc = []
@object = @abstract_model.new
satisfy_strong_params!
sanitize_params_for!(request.xhr? ? :modal : :create)
@object.set_attributes(params[@abstract_model.param_key])
@authorization_adapter && @authorization_adapter.attributes_for(:create, @abstract_model).each do |name, value|
@object.send("#{name}=", value)
end
# customization
if @object.class == Event
# do whatever you want
end
if @object.save
@auditing_adapter && @auditing_adapter.create_object(@object, @abstract_model, _current_user)
respond_to do |format|
format.html { redirect_to_on_success }
format.js { render json: {id: @object.id.to_s, label: @model_config.with(object: @object).object_label} }
end
else
handle_save_error
end
end
end
end
end
export
bulk_delete
show
edit
delete
show_in_app
end
end

我必须进行一次修改并删除satisf_strong_params!它再次非常hacky,但它确实有效:
RailsAdmin.config do |config|
config.actions do
dashboard # mandatory
index # mandatory
new do
controller do
proc do
if request.get? # NEW
@object = @abstract_model.new
@authorization_adapter && @authorization_adapter.attributes_for(:new, @abstract_model).each do |name, value|
@object.send("#{name}=", value)
end
if object_params = params[@abstract_model.to_param]
@object.set_attributes(@object.attributes.merge(object_params))
end
respond_to do |format|
format.html { render @action.template_name }
format.js { render @action.template_name, layout: false }
end
elsif request.post? # CREATE
@modified_assoc = []
@object = @abstract_model.new
satisfy_strong_params!
sanitize_params_for!(request.xhr? ? :modal : :create)
@object.set_attributes(params[@abstract_model.param_key])
@authorization_adapter && @authorization_adapter.attributes_for(:create, @abstract_model).each do |name, value|
@object.send("#{name}=", value)
end
# customization
if @object.class == Event
# do whatever you want
end
if @object.save
@auditing_adapter && @auditing_adapter.create_object(@object, @abstract_model, _current_user)
respond_to do |format|
format.html { redirect_to_on_success }
format.js { render json: {id: @object.id.to_s, label: @model_config.with(object: @object).object_label} }
end
else
handle_save_error
end
end
end
end
end
export
bulk_delete
show
edit
delete
show_in_app
end
