How to render a common JS from every action of controller?
问题
例如，我有一个名为Organizations的控制器，其中包括基本的CRUD操作和所有的respond_to JS操作，所以我在控制器的开头写了respond_to块，如下所示：respond_to :js, { only: %i[index destroy create] }，现在想要为所有这些操作渲染通用的JS，即希望在所有操作上渲染index.js.erb，而不是所有操作特定的JS。那么，对于这个问题，有什么解决方案呢？
英文:
For example, I have a controller named Organizations, which includes basic CRUD actions and all the actions respond_to JS, so I wrote the respond_to block at the beginning of the controller respond_to :js, { only: %i[index destroy create] } and now want to render a common JS for all these actions ie want to render index.js.erb on all actions rather than all action specific JS. So What can be the solution for the same?

你可以通过覆盖ActionController::ImplicitRender提供的default_render方法来覆盖隐式渲染。
class OrganizationsController < ApplicationController
def default_render(*args)
# 是否存在特定于操作的模板？
if template_exists?(action_name.to_s, _prefixes, variants: request.variant)
super
# 是否存在可用于索引的模板？
elsif template_exists?('index', _prefixes, variants: request.variant)
render :index, *args
# 我们没有模板。让默认渲染器处理错误
else
super
end
end
# ...
end
英文:
You can override the implicit rendering by overriding the default_render method provided by ActionController::ImplicitRender.
class OrganizationsController < ApplicationController
def default_render(*args)
# is there an action specific template?
if template_exists?(action_name.to_s, _prefixes, variants: request.variant)
super
# is there an index template we can use insted?
elsif template_exists?('index', _prefixes, variants: request.variant)
render :index, *args
# We don't have a template. lets just let the default renderer handle the errors
else
super
end
end
# ...
end
