refactoring - Rails helper methods with conditional parameters -


sometimes in rails views, have duplicated code, because have set parameters of rails helper method according conditions. like:

<% if %>   <%= link_to "target", @target, class: "target-a" %> <% else %>   <%= link_to "target", @target, class: "target-b" %> <% end %>

or example:

<% if tooltip == false %>   <%= image_tag picture.url(size), class: "img-responsive #{css_class}" %> <% else %>   <%= image_tag picture.url(size), class: "img-responsive #{css_class}", data: { toggle: "tooltip", placement: "bottom" }, title: "#{picture.name}" %> <% end %>

is there way of writing in more elegant way (without repeating whole helper)?

thanks

you can isolate differences in options hash , merge differences shared base options hash:

<%   link_options =      if       {}     else       { data: { toggle: "tooltip", placement: "bottom" }, title: "#{picture.name}" }     end %> <%= image_tag picture.url(size),                link_options.merge(class: "img-responsive #{css_class}") %>

or, better yet, same sort of thing in own, custom helper method. using helper method preferable because have method can tested, re-used, named (in self-documenting manner), etc.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
