当用户通过私人提交时,我们如何隐藏来自Feed的提交信息以及能够在其公开个人资料中看到它的其他用户？
<%= button_tag(type: 'submit',class: "btn") do %> ... <%= button_tag(type: 'submit',class: "btn",id: "2",name: 'private') do %> ...
我们将下面的内容放在控制器中,但由于私有按钮将包含许多不同的_forms,我是否必须将它放在每个控制器中,还是可以将它放在应用程序控制器中？
if params[:private] # the private action / What do we need to put here? else # normal submit / and here?
我跟着这个铁路播放节目几乎到了T来建立活动饲料：http://railscasts.com/episodes/406-public-activity.
以下是公开个人资料的代码：
users_controller.rb
def show @user = User.find(params[:id]) @habits = @user.habits @valuations = @user.valuations @accomplished_goals = @user.goals.accomplished @unaccomplished_goals = @user.goals.unaccomplished @averaged_quantifieds = @user.quantifieds.averaged @instance_quantifieds = @user.quantifieds.instance end
show.html.erb
<% if @user.habits.any? %>
<h2>Habits</h2>
<h4>Challenges</h4>
<%= render partial: 'habits',locals: {habits: @habits} %>
<% end %>
<% if @user.valuations.any? %>
<h2>Values</h2>
<%= render @valuations %>
<% end %>
<% if @user.goals.any? %>
<h2>Goals</h2>
<h4> Current</h4>
<%= render @unaccomplished_goals %>
<% end %>
<% if @user.goals.any? %>
<h4>Accomplished</h4>
<%= render @accomplished_goals %>
<% end %>
<% if @user.quantifieds.any? %>
<h2>Stats</h2>
<h4>Averaged</h4>
<%= render partial: 'averaged',locals: {habits: @averaged_quantifieds} %>
<% end %>
<% if @user.quantifieds.any? %>
<h4>Instance</h4>
<%= render partial: 'instance',locals: {habits: @instance_quantifieds} %>
<% end %>

有了K的答案,我会在转到用户或用户/ 1,用户/ 2等时收到此错误消息.

这是一个由两部分组成的问题.在这里找到第二部分：How to use private submit to hide from feed?
解决方法
将“private”字段添加到User模型,其默认值为“false”.所有普通用户信息都将被标记为“公共”(因为私有字段的值为false)仅当params [：private]时,私有字段的值才会设置为“true”.
接下来,您可以向用户模型添加一个方法,该方法将仅使用private = false标志(对于公共视图)获取用户的数据.
编辑：
显示公共或私人：
在每个可能被标记为私有的相关模型中添加“私有”字段.不要忘记在迁移中添加它.将private的默认值设置为false.
包括估值和用户迁移/架构
t.boolean :private,default: false
valuation.rb
def public? private == true ? false : true end
user.rb
# gets public valutations or nil,if there's no public valutation
def public_valuations
valuations.find(&:public?)
end
对于每个想要的关系,以同样的方式执行此操作.它使您能够通过获取公共信息
@valuations = @ user.public_valuations
您当前的show动作现在显示所有其他用户的信息 – 公共和私有 – 只有在current_user = @user时才会显示.
最后你必须在show动作中插入一个条件：
def show
@user = User.find(params[:id])
if current_user == @user
@habits = @user.habits
@valuations = @user.valuations
@accomplished_goals = @user.goals.accomplished
@unaccomplished_goals = @user.goals.unaccomplished
@averaged_quantifieds = @user.quantifieds.averaged
@instance_quantifieds = @user.quantifieds.instance
else
@valuations = @user.public_valuations
end
end
该解决方案依赖于current_user,即您必须具有返回当前logged_in用户的对象的方法(可能在会话中). Michael Hartl撰写了一篇关于用户身份验证的精彩tutorial. * RubyonRailsBeginner使用了Hartl教程:)
创建公共或私人记录
由于您已将private的默认值设置为false,因此您可以使用现有代码创建公共条目.
对于私有条目,您必须将user_params中的相应属性设置为true.
编辑params.require：
我将else子句中的[：private]显式设置为false,以便用户可以将其私有属性设置为public,如果需要的话.
def user_params
if params[:private] = true
params.require(:user).permit(:name,:private,:password_confirmation,valuations_attributes: [:name,:private])
else
params[:user][:valuations][:private] = false
params.require(:user).permit(:name,:tag_list])
end
end
Rails Api为您提供了有关嵌套属性的强参数的一些提示.
