Hey all, I’m getting a strange, unexplainable error. It returns undefined method `render\_index\_row\_action\_pprove’. I performed a search on my entire application and no such method exists. There is a render\_index\_row\_action\_approve but not a render\_index\_row\_action\_pprove. NoMethodError in Student\_requests#index Showing app/views/resources/index.html.haml where line #20 raised: undefined method `render\_index\_row\_action\_pprove’ for #ActionView::Base:0x105b3a780 Extracted source (around line #20): 17: = render\_index\_row\_index index 18: - resources\_index\_row(rsrc).each do |row| 19: = row 20: = render\_index\_row\_actions(rsrc, resources\_index\_row\_actions(rsrc), options) 21: - options[:with\_limit\_selector] = false 22: = render\_index\_bottom\_pagination\_bar options Is this a rails glitch, perhaps it is reading the method name wrong? Is there anyway to fix this? Thanks for any response. ---

Hi John, I would check your source code in app/views/resources/index.html.haml (or a view helper for that view) for a typo since it’s looking for a method named something similar to what you have (e.g change “render\_index\_row\_action\_pprove” to “render\_index\_row\_action\_approve”) HTH ---

When someone else downloaded a local copy from the repository, they got no such error. So either a modification needs to be made in the development log or there’s nothing else it appears I can do. Thanks for the response. ---

Thanks for the Usually when I get an error shown in a haml file then somewhere (in log or server window maybe) there will be a full trace which may identify a line in a helper causing the problem. I wonder if it some unprintable character is causing the problem so your search does not find it. I presume you have checked that you have no locally modified files. Also check that you have not got any extra files (backup files for example) in views/resources or helper folders. Rails has been known to pick up backup files instead of the correct file. What happens if you check out a new local copy from the repository? Colin ---
