ActionView::Base 中未定义的方法`html_fallback_for_js'

Question

我最近将一个项目升级为

ruby 3.2.2

和

rails 6.1

我遇到了

ActionView::Base

的问题。通过最近的升级，我需要将 3 个参数传递给

ActionView::Base.new

，而不是 2 个。从文档来看，

ActionView

现在接收

lookup_context, assigns, controller

view = ActionView::Base.new(
  ActionController::Base.view_paths, 
 {
  client: client,  
  report: self.report, 
},
nil
)

所以我通过传递

nil

来修复它（如上所示），但现在我得到了一个不同的错误：

actionview

版本是

6.1.7.3

Answer 1

在 Rails 6.1 中

ActionView::Base.new

需要 3 个参数：lookup_context、分配、控制器

但是您传递了

ActionView::PathSet

实例而不是

ActionView::LookupContext

这个对象没有这样的getter，这就是你有错误的原因

而不是将此包装路径设置到查找上下文中。另外，在新的 Ruby 中，如果名称与键名称相同，则不需要重复值

view =
  ActionView::Base.new(
    ActionView::LookupContext.new(ActionController::Base.view_paths),
    { client:, report: },
    nil,
  )

之后就可以使用这个视图进行渲染了

Answer 2

来自这个答案

我已将通话从

ActionView::Base.new

更改为

ActionView::Base.with_empty_template_cache.new

也是从上下文到

LookupContext

的参数之一，如下所示： 从

ActionController::Base.view_paths

到

ActionView::LookupContext.new(ActionController::Base.view_paths)

现在的通话如下所示：

   view = ActionView::Base.with_empty_template_cache.new(
      ActionView::LookupContext.new(ActionController::Base.view_paths), 
     {
      client: client, 
      report: self.report, 
    }, nil
    )
