当我的应用程序被推送到 heroku 时,我在应用程序中遇到了一个奇怪的错误。该应用程序在我的本地机器上运行良好。我不知道是不是因为我在本地使用Mysql?
这是我得到的错误:
2012-07-24T17:14:52+00:00 app[web.1]: ActionView::Template::Error (PG::Error: ERROR: argument of AND must be type boolean, not type integer
2012-07-24T17:14:52+00:00 app[web.1]: : SELECT COUNT(*) FROM "users" INNER JOIN "articles_users" ON "users"."id" = "articles_users"."user_id" WHERE "articles_users"."article_id" = 64 AND (1)):
2012-07-24T17:14:52+00:00 app[web.1]: 9: <span>

2012-07-24T17:14:52+00:00 app[web.1]: 11: <%if user_signed_in?%>
2012-07-24T17:14:52+00:00 app[web.1]: 12: <%if a.likes.where(user_id = current_user.id).size == 0%>
2012-07-24T17:14:52+00:00 app[web.1]: 13: <%=image_tag("star.png", :width => "37", :height => "36", "data-action" => "star")%></a><span data-action="likes" style="vertical-align:10px; padding:8px;">
2012-07-24T17:14:52+00:00 app[web.1]: 14: <%else%>
2012-07-24T17:14:52+00:00 app[web.1]: 15: <%= image_tag("star-yellow.png", :width => "37", :height => "36", "data-action" =>"star")%></a><span data-action="likes" style="vertical-align:10px; padding:8px;">
这是我认为的代码:
<a data-action="like" data-id="<%= a.id %>" >
<%if user_signed_in?%>
<%if a.likes.where(user_id = current_user.id).size == 0%>
<%= image_tag("star.png", :width => "37", :height => "36", "data-action" => "star")%></a><span data-action="likes" style="vertical-align:10px; padding:8px;">
<%else%>
<%= image_tag("star-yellow.png", :width => "37", :height => "36", "data-action" => "star")%></a><span data-action="likes" style="vertical-align:10px; padding:8px;">
<%end%>
这里出了什么问题?先谢谢了!
