闪存不在Rails的相同视图中显示。
闪存不在Rails的相同视图中显示。
提问于 2022-04-04 07:50:44
在成功地更新对象之后，我需要在相同的视图(：编辑)中显示闪存。如果我重定向到另一个动作-一切都正常。但当我需要呆在里面时:编辑-不起作用。谁能给我解释一下我的错误..。谢谢!
我的控制器中有以下代码片段：
def edit
@setting = Setting.find_by(slug: current_user)
end
def update
@setting = Setting.find_by(slug: current_user)
if @setting.update(settings_params)
flash[:success] = I18n.t('admin.settings.edit.success')
else
flash[:danger] = I18n.t('admin.settings.edit.not_saved')
end
redirect_to edit_admin_setting_url(user: current_user)
endroutes.rb
scope ":user/" do
namespace :admin do
resource :setting, only: [:edit, :update]
end
end和edit.html.erb
<% if flash[:success].present? %>
<div class="<%= classes + "alert-success" %>">
<%= icon("fas", "check") %>
<%= flash[:success] %>
<button type="button" class="close" data-dismiss="alert" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<% end %>我也试过：
flash.now[:success] = I18n.t('admin.settings.edit.success')
render :edit也不管用。

在Rails 7中，turbo希望POST / PUT /修补程序表单提交可以重定向，通常是创建和更新控制器操作。
若要呈现模板，响应必须具有无效状态(如:unprocessable_entity )，否则turbo将在浏览器控制台中显示错误：
turbo.es2017-esm.js:2115 Error: Form responses must redirect to another location
at k.requestSucceededWithResponse (turbo.es2017-esm.js:679)
at A.receive (turbo.es2017-esm.js:450)
at A.perform (turbo.es2017-esm.js:431)这是设置更新操作的一种方法：
# GET /:user/admin/setting/edit
#
# renders edit.html.erb
def edit
@setting = Setting.find_by(slug: current_user)
end
# PATCH /:user/admin/setting
#
# redirects to user on success
# renders edit.html.erb on failure
def update
@setting = Setting.find_by(slug: current_user)
if @setting.update(settings_params)
# when setting updated
flash[:success] = "Success" # set a message to show on the next request;
# we have to redirect to another url
redirect_to user_url(current_user)
# redirect some place else, like user profile
# this means we're done with `update` action
# and with current request
else # when update/validation failed
# we cannot redirect, because we'll loose our
# invalid object and all validation errors
# NOTE: sometimes if redirect is required
# errors can be assigned to `flash`
flash.now[:danger] = "Oops" # set a message to show in this request;
# we have to render a response
# NOTE: this might be unnecessary, because form
# will also show validation errors
render :edit, status: :unprocessable_entity
# render edit.html.erb template,
# this means we're staying in `update` action
# and in current request
# NOTE: this has nothing to do with `edit`
# action at the top
end
end您还可以使用rails生成器获得一个快速启动代码，并举例说明一切如何工作。
