问题描述
我想将参数 recipient 传递给控制器.我可以像这样在我的视图中显示它:
@recipient.username如何将此值传递给 params[:message][:recipient]?请注意，我没有名为消息"的模型.
controllers/messages_controller.rb
def 交付收件人 = User.find_by_username(params[:recipient])主题 = 参数 [:主题]body = params[:body]current_user.send_message(收件人，正文，主题)重定向到:控制器 =>'消息', :action =>'已收到'flash[:notice] = "消息已发送！"结尾views/messages/new.html.erb
:messages, :action => :deliver ) do |f|％＞<div class="field"><%= f.label :subject%><br/><%= f.text_field :subject %><div class="field"><%= f.label :body %><br/><%= f.text_field :body %>
<div class="actions"><%= f.submit %><%结束%>
解决方案 您可以通过为您的 Recipient 分配一个 attr_accessible 键并将其分配给表单来实现.
form_for :message do |f|f.hidden_field :recipient_id, :value =>@recipient.id.to_if.text_field :messagef.提交结尾
一旦您将其传递给您的创建操作，您就可以检查 params[:message][:recipient_id]
并将其传递给数据库.
玩得开心
I'd like to pass the parameter recipient to controller. I can show it in my view like this:
@recipient.username
How can I pass this value to params[:message][:recipient]? Note that I do not have a model called "Message".
controllers/messages_controller.rb
def deliver
recipient = User.find_by_username(params[:recipient])
subject = params[:subject]
body = params[:body]
current_user.send_message(recipient, body, subject)
redirect_to :controller => 'messages', :action => 'received'
flash[:notice] = "message sent!"
end
views/messages/new.html.erb
<td><%= @recipient.username if @recipient %></td>
<%=form_for :messages, url: url_for( :controller => :messages, :action => :deliver ) do |f| %>
<div class="field">
<%= f.label :subject %><br />
<%= f.text_field :subject %>
</div>
<div class="field">
<%= f.label :body %><br />
<%= f.text_field :body %>
</div>
<div class="actions">
<%= f.submit %>
<% end %>
解决方案 You could do this by assigning an attr_accessible key for your Recipient and assign it to the form.
form_for :message do |f|
f.hidden_field :recipient_id, :value => @recipient.id.to_i
f.text_field :message
f.submit
end
once you pass this to your create action you are able to check params[:message][:recipient_id]
and pass this to the db.
Have fun
