Thanks Kevin,
The part mechanism certainly seems like a good logical step in
updating specific sections of the page, I like it! :)
I had a look at a lambda in the named scope, but this seemed to
restrict what I was trying to achieve with my particular models and
fields.
What I have managed to build so far is:
my controller method -----
def finishedArticle
@myOption = params[:stateSelect]
if @myOption == 'Latest'
@page =
Page.finished_pages.latest_finished.apply_scopes( :search =>
[params[:search], :page, :created_at ], :order_by =>
parse_sort_param(:page, :created_at )).paginate(:per_page => 25, :page
=> params[:page])
else
@page = Page.finished_pages.apply_scopes( :search =>
[params[:search], :page, :created_at], :order_by =>
parse_sort_param(:page, :created_at :)).paginate(:per_page =>
25, :page => params[:page])
end
end
Then in my view for finished Articles, I have:
<%= select_tag "stateSelect", options_for_select(['All', 'Latest'],
'All'), { :onchange => remote_function(
:update => 'finishedArticles',
:with => 'Form.Element.serialize(this)',
:url => {:action =>
'finishedArticles'}) } %>
<table-plus part='finished_article_table' with="&@page fields="page,
created_at" >
</table-plus>
I feel like I am almost there with what I am trying to achieve, the
webpage loads initially with all of the finished articles showing in
the table, and when I use the select menu, to choose 'Latest, I can
see from the console that the correct data is extracted from the
database - and has picked up the chained named scope - (if @myOption =
'Latest' .... Page.finished_pages.latest_finished), however, I cannot
get the contents of the table to update. If I change :update =>
'finishedArticles', to :update => ''finished_article_table', I get a
blank page with the text 'Latest' shown in the top corner?
I have thought about trying to use render :update do |page|
page.replace_html, 'theTable' 'relevant code to replace table'- but I
am unsure how to call the html correctly here to render the changed
table on the webpage?
Any help here would be greatly appreciated!
Thanks again
Pete
