Greetings All,
I hope you all understand what I am writing here. Lots of views involve
displaying date from static 'look up' tables: states, countries, type...
>From all of the documentation I have read, the standard code conduct seems
@look_up_object = LookUpModel.find .where. conditions => ids match
I pursued that structure, and for long listings, so many calls to database
really bothered me.
So I re-wrote the code on look-up for my case static item_conditions,
containing only two field: conditions and item_conditions_id:
In the view I now have, following found parent records:
<% @icond = Itemconditions.find(:all, :readonly) %>
<% @ih = Hash.new %>
<% @ih2 = Hash.new %>
<% @ih = @icond.to_a.map(&:serializable_hash) %>
<% for kv in @ih %>
<% @ih2[kv.fetch("item_conditions_id")] = kv.fetch("conditions")
%>
<% end %>
And then later for iterative record output I have in the view, ldr as the
parent data source
<label class="item_listing">Condition: <%=
@ih2[ldr.item_condition_id.to_s] %></label>
Benchmarked this and vastly faster. Deployed it, no problems/errors. I
have researched Ruby and Ruby on Rails API. I have not found a simpler,
more native approach. Masters if you are aware of Ruby on Rails way,
please let me know.
Thanks,
Liz McGurty
