Is there a way to append data (e.g. {:foo => 6}) for all json responses so codes such as render :json => {..} would become {"foo": 6, ...}?
I tried to create a json layout in app/views/application.json.erb but didn't seem to make a difference.
The code I'm using is often similar to:
respond_to do |format|
format.html
format.json { render json: {..} }
end
I kind of got it working when using a json view but it is a bit cumbersome to create a view for each response.
使用active_model_serializers，定义一个自定义序列化程序并为每个模型的序列化程序继承它。
假设我们有Bar一个Baz模型。然后我们为每个定义序列化器：
class FooSerializer < ActiveModel::Serializer
attributes :foo
def foo
6
end
end
class BarSerializer < FooSerializer
attributes :id, :attr_one, :attr_two
# ...
end
class BazSerializer < FooSerializer
attributes :id, :attr_1, :attr_2
# ...
end
这应该{ foo: 6 }在包含这些模型的每个响应中返回。例子：
{ bar: { foo: 6, id: 1, attr_one: "something", attr_two: "something" } }
{ baz: { foo: 6, id: 1, attr_1: "something", attr_2: "something" } }
您可以拥有布局并设置通用属性。您可以通过解析产量来休息。
