[Archivesspace_Users_Group] RoR Guidance/Help with Index Page

[Brian Hoffman]

Hi Maura,

Are you trying to add a controller to ArchivesSpace or are you trying to create a standalone web app? If the former, you should probably package it as a plugin. More info here:

https://github.com/archivesspace/archivesspace/blob/master/plugins/PLUGINS_README.md

Either way, it would be easier to diagnose your issue if you put an actual repository on Github.

Also, although this doesn’t look right

def index

def pickImage(directory)
  dirSize=directory.length
  ranNum=0+rand(dirSize)
  fileName=directory[ranNum]
  return fileName
end
end


Instead:

def index

 @filename = pickImage

end

def pickImage(directory)
  dirSize=directory.length
  ranNum=0+rand(dirSize)
  directory[ranNum]
end

Then in a typical RoR system @filename will be available to views/index.html.erb


Brian

Hoping someone with more experience may be able to offer a little guidance as the stuff I've read hasn't been super helpful (in part because I'm already working with pre-built stuff rather than starting entirely from scratch).

I found the index controller (I believe), the site_controller.rb and put the code inside (and outside on a few tries) the def index end block, and then added an <img src="<%= @img1 %>" /> to my index.html.erb file but no variable is found (the page display but its like the img tag is empty).
