parameters

<% for post in @posts %>

<%= link_to_remote "Edit", :url => { :controller => "threads", :action => :new_req }, :with => "'description=#{post.description}'"

<% end %>

When I make a post with the form and enter a description like such:

Description text_area: this is a description that has linebreaks, or... at least, I have pressed enter several times.

It can save fine when made with the form. But in my first code, when I try to set params[:description] = post.description, it doesn't work properly. Not sure why. It only happens when I make a description and hit enter one or more times (have linebreaks)...

Any help is much appreciated!

Thanks

You don't need to use :with for this. But apart from that, the problem
is that you're not escaping the description. The post I linked you to
the other day about the usage of the :with parameter covered both of
these things.

The encodeURIComponent doesn't seem to make a difference.

Mmm.. a user fills out the textarea with a form_for (for a model object). When I do <% for post in @posts %> <%= post.description %> It doesn't show the linebreaks that I entered. So if I enter (into the textarea): dsfksdf (enter) sdfsdf (enter) sfdsdf

I guess it doesn't save it in the first place because with <%= post.description %> I get dskfsdf sdfsdf sfdsdf. But I can't even send that as a parameter to populate a form.

Any suggestions would be greatly appreciated!

Ah, I misunderstood what wasn't working. HTML ignores linebreaks so what you're seeing is normal. you either need to be inserting your own <p> or <br> tags or wrapping your text in <pre> tags. The simple_format helper will do the former for you.

Hey Fred, I'm still having some problems =\

In my first post: <% for post in @posts %>

<%= link_to_remote "Edit", :url => { :controller => "threads", :action => :new_req }, :with => "'description=#{post.description}'"

<% end %>

1. You said I didn't need to use :with. How would I access the post.description otherwise? 2. I used the simple_format helper, so it displays correctly now, but 3. Still having trouble calling my 'new_requirement' action to edit, with: view: <% for post in @posts %>   <%= link_to_remote "Edit", :url => { :controller => "threads", :action => :new_req }, :with=>"'req_id=#{post.requirement_id}' + '&' + 'title=#{post.title}' + '&' + 'description=' + '#{simple_format(post.description)}' + '&' + 'justification=#{post.justification}' + '&' + 'tags=#{post.tags}'", :class=>"edit" %> <% end %>

controller:   def new_requirement     @post = Post.new

    respond_to do |format|           format.html { redirect_to_index}           format.js         end   end

rjs page.replace_html :control, :partial => 'new_req' page[:control].visual_effect :slide_down

partial: <% form_for :post, :url => { :action => :save_requirement } do |form| %> <%= form.text_area :description, :value => params[:description], :class => "textarea" %> <% end %>

Thanks for helping me out!

stick it in the :url hash.

I'm not entirely sure what you're doing here. You're passing a bunch
of parameters to this action but then you're not using any of them.
And why pass all those parameters when you could just as easily pass
the post id ?

Fred

Never mind. Finally, I figured it out. I think passing the post_id instead of all the params made the difference.

Thanks for all the continued help Fred!!!!!!
