我有2个控制器:欢迎(处理主页)和邀请(帮助人们创建/管理邀请)。我试图在邀请视图中的两个部分上使用相同的welcome.html.erb
:_form.html.erb
(用于创建邀请)和_results.html.erb
(通过Ajax在同一welcome.html.erb
上显示邀请页)。
邀请的查看文件夹中也有create.js.erb
。
输入工作正常,但没有实时更新。我仍然需要刷新页面。有人知道我在做什么错吗?
_form.html.erb
代码是:
<h3 class="section_title"> Express meeting request IR </h3>
<div id="theform">
<%= simple_form_for invitation do |f| %>
<%= f.error_notification %>
<%= f.error_notification message: f.object.errors[:base].to_sentence if f.object.errors[:base].present? %>
<%= f.label "Dest." %>
<%= f.collection_select(:guest_id, User.all, :id, :full_name, {}, class: "selectpicker", title: "Choose recipient", multiple: true, data: {style: "form-control", size: "200", width: "100%"}) %>
<br><br>
<%= f.input :event_id %>
<%= f.input :start %>
<%= f.input :title %>
<%= f.input :type_of_event %>
<%= f.label "Memo" %> <br>
<%= f.text_area :memo, as: :text, class: "text_area_iro", rows: 5 %>
<div class="form-actions">
<%= f.button :submit, class: "btn-custom"%>
</div>
<% end %>
</div>
_result.html.erb
(某些表格标题已删除)如下:
<% @invitationsR.each do |invitation| %>
<tr>
<td><%= find_name(invitation.user_id) %></td>
<td><%= invitation.start %></td>
<td><%= TypeEvenement.find_by(id: invitation.type_of_event).type_name %> </td> </tr>
<% end %>
create.js.erb
如下:
$("#theform").html("<%= escape_javascript(render :partial => 'invitations/result', :locals => {:invitation => @invitation}) %>");
Welcome.html.erb
看起来
<%= render :partial => 'invitations/form', :locals => {:invitation => Invitation.new} %>
<%= render :partial => 'invitations/result', :locals => {:invitations => @invitations} %>
控制器和普通的new和create方法一样。 创建方法如下:
def create
@listmail = params[:invitation][:guest_id]
@listmail = @listmail.join(' ').split
@listmail.each do |v|
@invitation = current_user.invitations.build(invitation_params)
@invitation.guest_id = v
puts(v)
@invitation.save!
end
if @invitation.save
redirect_to invitations_path
else
render 'new'
end
end

您有一些错别字和遗漏之处。
在您的create方法中,您需要定义一个名为@invitations
的实例变量,您将在局部变量中将其作为局部变量传递到create.js.erb
文件中:
def create
---- skip code ----
@invitation.save!
end
@invitations = current_user.invitations # define this one
if @invitation.save
---- skip code ----
end
现在您定义了变量,因此在create.js.erb
文件中将是:
$("#theform").html("<%= escape_javascript(render :partial => 'invitations/result', :locals => {:invitations => @invitations}) %>");
在_result.html.erb
中:
<% invitations.each do |invitation| %>
## Content
<% end %>
答案 1 :(得分:2)
1 =>添加远程:remote=> true
,以通过ajax请求提交表单。
<%= simple_form_for invitation, id: "invitation_form", :remote=> true do |f| %>
###Content
<%end%>
2 =>将结果部分包装在一个单独的ID中,如下所示:-
<%= render :partial => 'invitations/form', :locals => {:invitation => Invitation.new} %>
<div id "result_partial">
<%= render :partial => 'invitations/result', :locals => {:invitations => @invitations} %>
</div>
3 =>始终最好在局部即局部使用局部变量(邀请而不是@invitations)
在_result.html.erb
<% invitations.each do |invitation| %>
<tr>
<td><%= find_name(invitation.user_id) %></td>
<td><%= invitation.start %></td>
<td><%= TypeEvenement.find_by(id: invitation.type_of_event).type_name %> </td>
</tr>
<% end %>
4 =>重构创建动作(即始终使用应以html或js格式响应的格式)
def create
@listmail = params[:invitation][:guest_id]
@listmail = @listmail.join(' ').split
@listmail.each do |v|
@invitation = current_user.invitations.build(invitation_params)
@invitation.guest_id = v
puts(v)
if @invitation.save!
@invitations = current_user.invitations #get all invitations including new invitations that has been saved just now
respond_to do |format|
format.html{ redirect_to invitations_path }
format.js { render :layout => false }
end
else
window.location = "http://localhost:3000/invitations.new";
end
end
end
5 =>回复后
$('#invitation_form').[0].reset(); #reset form
$("#result_partial").html("<%= j render partial: 'invitations/result', :locals => {:invitation => @invitation}) %>"); #Refresh only results
答案 2 :(得分:1)
以下代码可在Ajax验证后清除表单:
$("#result_partial").html("<%= j render partial: 'invitations/result', :locals => {:invitation => @invitation} %>");
$("#result2_partial").html("<%= j render partial: 'invitations/result2', :locals => {:invitation => @invitation} %>");
$("#theform").remove();
$('#invitation_form').html("<%= j render partial: 'invitations/form', :locals => {:invitation => Invitation.new} %>");
别忘了用以下命令重置select2项:
$(document).ready(function(){$('#invitation_guest_id').select2({
placeholder: "Contact name, list or company",
minimumInputLength: 3
});
});
