用户使用Devise和Rails登录时打开模式

Question

I have a rails app with Devise . I would like to open a modal dialog when a user sign in the website.

My current solution is that add a url params in after_sign_in_path_for method:

def after_sign_in_path_for(resource_or_scope)
  root_url(sign_in: true)
end

And then I can check the url params in javascript:

<script type="text/javascript">
  <% if params[:sign_in] %>
    $(document).ready(function() {
      $('#login-message-modal').modal()
    });
  <% end %>
</script>

But I feel it is tricky. Does anyone know any better solution?

Cheers

Answer 1

def after_sign_in_path_for(resource_or_scope)
  flash[:modal] = '#login-message-modal'
  root_url
end

and

<script>
  ....
  <% if flash[:modal] %>
     $('<%= flash[:modal] %>').modal();
  <% end %>
</script>
