2 Issues - On load component hiding ; Separate find methods


#1

I have been working on developing a blog site using rails. This is my
first rails application, hence I am fairly new to rails development.
Over the past week, I have encountered a few issues and hence I am
putting them all in one post here. Please feel free to comment on any
of the below mentioned issues:

  1. On my blog post I have my blog entries and their respective
    comments. The visibility of the comments is toggled using a link. When
    my blog page loads, the comments are being displayed by default.
    However I want to hide the comments on page load and show them only
    when the “Comments” link is clicked. I am using rjs to toggle the
    visibility. Is there a way to hide the comments on page load? The code
    that I have is shown below:

//Comments link: (blog.html.erb)
<%= link_to_remote pluralize(blogentry.comments.size, ‘Comment’), :url
=> { :action => ‘show_comments’, :entry => blogentry}%>

//RJS Templates : (show_comments.js.rjs)
entry = params[:entry]
page.visual_effect :toggle_blind, “Comment_box_#{entry}” , :duration
=> 0.5, :fps => 50

  1. I have also tried to categorize and archive the blog entries. For
    that I am calling custom find methods. They are working fine and
    everything is being done in the same method in the controller. Also I
    have a single view file. However I would like to know if there is a
    better way of doing this. Should I perform the find in separate
    methods and have separate view files for each find (like separate view
    for archives and categories)? Although I don’t think that would be a
    DRY implementation. The code is shown below:

//page controller
def blog
@category = Category.find_by_name(params[:category_name])
if (params[:category_name])
@blogentries = Blogentry.find_all_by_category_id(@category.id)
elsif (params[:month] && params[:year] )
start = Time.mktime(params[:year], params[:month])
@blogentries = Blogentry.find(:all, :conditions => ['created_at

? and created_at < ?’, start, start.next_month])
else
@blogentries = Blogentry.find(:all)
end
end

//blog.html.erb
<% for blogentry in @blogentries %>

<%= h blogentry.title %>
<%=h blogentry.body %>
<% end %>

//layout.html.erb (only the sidebar code with Archives and
Categories).
//This file provides the category, month and year required for
categorizing and archiving //respectively.

CATEGORIES
<% for category in @categories%> <% @entry = Blogentry.findforCatergoryid(category.id) %> <%= link_to category.name.upcase + "(#{@entry.length})", category_entries_path(category.name)%> <% end%>
ARCHIVES
<% @entries_by_month.each do |month, entry|%> <%= link_to month.strftime('%B %Y').upcase, archive_path (month.strftime('%Y'), month.strftime('%m'))%> <% end%>

Any help here will be be greatly appreciated.

Thanks,
vishy

to answer your first question, hiding the comments by default is easy.
simply add a “display:none” to the CSS for the divs you wish to be
hidden initially.
