similar to: Idiomatic way to change partial''s behavior based on caller

i''m working on a _post.rhtml partial, and it displays one blog post. i''m accessing this partial on the list.rhtml and the show.rhtml what i''d like is to only show the "link" link on the list.rhtml and not on the show page. <%= post.title%> <br /> <%= post.body%> <%= link_to

hi all this works <%= render :partial => "admin/works/work", :collection => @artist.works %> but this doesn''t <%= render :partial => "admin/works/worklist", :collection => @artist.works %> even though the partial _work.rhtml and _worklist.rhtml are identical. worklist.rhtml throws undefined local variable or method

Considering the python code: for k, v in d.items(): do_something(k); do_something_else(v) I have the following for R: for (i in c(1:length(d))) { do_something(names(d[i])); do_something_else(d[[i]]) } This does not seem seems idiomatic. What is the best way of doing the same with R? Thanks. Luis

Hello. I''m using the Agile Web Dev. book 1st Edition and I''m puzzled by the code on pp. 83-84. <%= link_to ''Add to Cart'', {:action => ''add_to_cart'', :id => product }, :class => ''addtocart'' %> def add_to_cart product = Product.find(params[:id]) @cart = find_cart

Folks, I''m trying to write a validating filter that checks if the user exists and renders XML if not. Most of the controllers will be returning XML on some error or other so I''m including RenderError in ApplicationController. Is my approach a sound one? Also, is there a shorter and more idiomatic way of writing this: if @user.nil? render_user_exists

I have proposals and members can vote for them. In my proposal view I have a little div where the currently logged in member can vote: <div id="vote_div" class="vote"> Your vote: <% if @member_vote %> You have voted for this proposal<br /> <%= start_form_tag :action => "delete_vote" %> <%= hidden_field_tag :id,

Hello, I have a vector of 1,000,000 numbers and another vector of 1,000 divisors. What I'd like to do is to divide the first 1,000 numbers of the first vector by the first divisor, then the next 1,000 by the second divisor and so on. I came up with this, but I was wondering if there is a more idiomatic, R-like way to write it: x <- ... divs <- ... for (i in seq(from = 1, to = 1000000,

Is there a more elegant way of writing this? def verify_user @user = User.find_by_username params[:username] if @user.nil? message = xml.error do |xm| xm.message "User does not exists: #{params[:username]}" end render :xml => message return false else true end end Thanks, Joel --

I''m doing layouts and I have a question on how to process <%= ... %> tags within partials. I have a standard.rhtml file with : <div id="header"><%= render_partial "layouts/header" %></div> and my _header.rhtml contains a tag as such: <link_to "Categories", :controller => "categories", :action=> "list"

I have a class which stores as one of its attributes a day of the week as an integer (0-6, 0=Sunday, standard UNIXy values). I want, obviously, the views to show the weekday name and the forms to provide a drop-down with the weekday names. Essentially it''s a vrtual attribute whose value is the localized weekday name, which maps to the integer value that''s actually stored.

Go API functions returned (<val>, *GuestfsError) that made code like this fail to build: n, err := os.Stdin.Read(buf) if err != nil { log.Fatal(err) } n, err = g.Pwrite_device(dev, buf[:n], off) ... As err should be of error (interface) type as of the stdlib call, and should be of *GuestfsError type as of the libguestfs call. The concrete error value that

Hey guys, I''m having a little trouble working out partials. I have successfully made a partial work in my list.rhtml, but as I see it on the 15min introductry video. They guy uses one partial on multipul pages. At the moment I am trying this in my show.rhtml, I write <%= render :partial => "journal" %> and I get this. NoMethodError in Write#show > > Showing

Hi RoR Community, in Ryan Bates Railscasts Episode #262 he put the index code <% for message in @messages %> <div class="message"> <div class="created_at"><%= message.created_at.strftime("%B %d, %Y") %></div> <div class="content"> <%= message.content %> </div> <div

I have been trying all kinds of different ways to produce what I think should be a simple effect, but have not had any luck yet and apparently I am not following the general idea... What I am trying to accomplish is the following (part 1 works and part 2 does not): 1. One of my views has a link_to_remote which updates a div container with a table of data my example is <div

Prefer named constants over magic numbers in the 'struct option' list, and expand the list of enums for long-only options so that the call to getopt_long() can switch directly to every option, rather than needing a lengthy if/else chain that grows for every new long option.

my view contains a call to a partial: <%= render(:partial => ''item_list'', :collection => @keyword.synonyms, :locals => { :action_delete => "removesynonym", and_some_other_stuff }) %> _item_list.rhtml contains: <%= link_to ( image_tag(''/images/deletebutton.png''), { :action => action_delete, :id =>

I have a search page with a text_field as below <%= text_field ''program'', ''program_name'' %> After I perform the search in my controller I go to a search results view which shows search results and uses Rails pagination. Now how to pass the search paramters (i.e. params[:program][:program_name] in my controller) to the pagination links (next and

Hi, Sebastian Kanthak of the file_column-Plugin wrote once: "is the photo object inside a local variable or an instance variable (e.g. photo or @photo)? url_for_file_column only works with instance variables, like all other active record form helpers. Could this be the problem?" So I''m using file_column in a partial, e.g. <%= render (:partial => "product",

I think the link_to helper method is quite confusing with its arguments order: link_to body, url link_to "Click me", @person Why is it thay way round? I want to make a "link to [the] person", so I would expect the order to be: link_to @person, "Click me" It reads much more natural. You don''t "link to [the] body", you "link to
