Rubyonrails 如何让删除链接响应 Rails 7 中的 turbo_stream 和 html

我已经提到了headers a few次recently次，所以我将这一部分保持简短:

当您发送TURBO_STREAM请求时，优先的第一个格式是turbo_stream.如果没有turbo_stream格式块或turbo_stream.erb模板，则使用html格式.因为turbo可以处理这两个响应，所以它设置Accept标头来确定要运行哪个格式块.你可以从destroy行动中看一看:

puts request.headers["Accept"]
#=> text/vnd.turbo-stream.html, text/html, application/xhtml+xml
#   ^                           ^
#   turbo is first in line      html is second

def destroy
  @model.destroy

  respond_to do |format|
    format.turbo_stream { render turbo_stream: turbo_stream.remove(@model) }
    format.html { redirect_to models_url, notice: "Destroyed." }
  end
end

To get a turbo_stream response

<%= link_to "Turbo destroy", model_path(model),
  data: {turbo_method: :delete}
%>

To get an html response

Rails还可以忽略Accept报头并根据URL扩展来确定格式.呼叫/models/1.html的涡轮增压请求将以html回应.

<%= link_to "HTML turbo destroy", model_path(model, format: :html),
  data: {turbo_method: :delete}
%>

<%= button_to "HTML turbo destroy", model_path(model, format: :html),
  method: :delete
%>

我最不喜欢的turbo: false个选项，讨厌:

<%= button_to "HTML rails destroy", model_path(model),
  method: :delete,
  data: {turbo: false}
%>

Use url/form params to do whatever you want

<%= button_to "Turbo destroy with params", model_path(model),
  method: :delete,
  params: {redirect_to: "/anywhere/you/like"} # or maybe just true/false
%>

def destroy
  @model.destroy

  respond_to do |format|
    # just pass a param and disable the turbo_stream block
    unless params[:redirect_to]
      format.turbo_stream { render turbo_stream: turbo_stream.remove(@model) }
    end
    format.html { redirect_to (params[:redirect_to] || models_url), notice: "Destroyed." }
  end
end

如果这仍然不能解决问题，您可以发送您自己的fetch个请求，并且只为您需要的格式设置一个Accept头.请参阅顶部的链接.
