  • JSON is not nested in rails view

    - by SeanGeneva
    I have a several models in a heirarchy, 1:many at each level. Each class is associated only with the class above it and the one below it, ie: L1 course, L2 unit, L3 unit layout, L4 layout fields, L5 table fields (not in code, but a sibling of layout fields) I am trying to build a JSON response of the entire hierarchy. def show @course = Course.find(params[:id]) respond_to do |format| format.html # show.html.erb format.json do @course = Course.find(params[:id]) @units = @course.units.all @unit_layouts = UnitLayout.where(:unit_id => @units) @layout_fields = LayoutField.where(:unit_layout_id => @unit_layouts) response = {:course => @course, :units => @units, :unit_layouts => @unit_layouts, :layout_fields => @layout_fields} respond_to do |format| format.json {render :json => response } end end end end The code is bring back the correct values, but the units, unit_layouts and layout_fields are all nested at the same level under course. I would like them to be nested inside their parent.

  • Simple user control for conditionally rendering nested HTML

    - by Goyuix
    What I would like to do, is be able to pass two attributes to a user control, a ListName and a Permission, like so: <uc:check id="uc" List="Shared Documents" Permission="OpenItems" runat="server"> <!-- have some HTML content here that is rendered if the permission is true --> </uc:check> Then in the actual check user control, have something similar to: <%@ Control language="C#" ClassName="check" %> <% // determine permission magic placeholder if (DoesUserHavePermissions(perm)) { // render nested HTML content } else { // abort rendering as to not show nested HTML content } %> I have read the page on creating a templated control on MSDN, and while that would work - it really seems to be a bit overkill for what I am trying to do. Is there a control that already renders content based on a boolean expression or a simpler template example? http://msdn.microsoft.com/en-us/library/36574bf6.aspx

  • Removing items from a nested list Python

    - by johntfoster
    I'm trying to remove items from a nested list in Python. I have a nested list as follows: families = [[0, 1, 2],[0, 1, 2, 3],[0, 1, 2, 3, 4],[1, 2, 3, 4, 5],[2, 3, 4, 5, 6]] I want to remove the entries in each sublist that coorespond to the indexed position of the sublist in the master list. So, for example, I need to remove 0 from the first sublist, 1 from second sublist, etc. I am trying to use a list comrehension do do this. This is what I have tried: familiesNew = [ [ families[i][j] for j in families[i] if i !=j ] for i in range(len(families)) ] This works for range(len(families)) up to 3, however beyond that I get IndexError: list index out of range. I'm not sure why. Can somebody give me an idea of how to do this. Preferably a one-liner (list comprehension). Thanks.

  • jQuery Nested Droppables

    - by John
    I have a nested set of jQuery droppables...one outer droppable that encompasses most of the page and an a set of nested inner droppables on the page. The functionality I want is: If a draggable is dropped outside of any of the inner droppables it should be accepted by the outer droppable. If a draggable is dropped onto any of the inner droppables it should NOT be accepted by the outer droppable, regardless of whether the inner droppable accepts the draggable. So that would be easy if I could guarantee 1+ inner droppables would accept the draggable, because the greedy attribute would make sure it would only get triggered once. Unfortunately the majority of the time the inner droppable will also reject the draggable, meaning the greedy option doesn't really help. Summary: The basic functionality is a set of valid/invalid inner droppables to accept the draggable, but when you toss the draggable outside any of the draggables it gets destroyed by the outer droppable. What's the best way of doing this?

  • Not quite nested inlines?

    - by Lynden Shields
    Not quite sure what to call this, it's not quite nested inlines, but is probably related. I have a 3 level hierarchy of objects, A one-to-many B one-to-many C. Therefore, every C implicitly also belongs to an A. class A(models.Model): stuff = models.CharField("Stuff", max_length=50) class B(models.Model): a = models.ForeignKey(A) class C(models.Model): b = models.ForeignKey(B) I would like all C's that belong to an A to be listed on the admin page for A in an in-line. They do not have to show which B they belong to on the same page. Is this possible or is it the same problem as nested inlines anyway? If it's possible, how do I do it? I'm using django 1.3

  • Select Elements in nested Divs using JQuery

    - by PIKP
    I have the following html markup inside a Div named item and I want to select all the elements (inside nested divs) and clear the values. As shown in following given Jquery I have managed to access elements in each Div by using.children().each(). But the the problem is .children().each()goes one level down at a time from the parent div, so I have repeated the same code block with multiple .children() to access the elements inside nested Divs, can anyone suggest me a method to do this without repeating the code for N number of nested divs . html markup <div class="item"> <input type="hidden" value="1234" name="testVal"> <div class="form-group" id="c1"> <div class="controls "> <input type="text" value="Results" name="s1" maxlength="255" id="id2"> </div> </div> <div class="form-group" id="id4"> <input type="text" value="Results" name="s12" maxlength="255" id="id225"> <div class="form-group" id="id41"> <input type="text" value="Results" name="s12" maxlength="255" id="5"> <div class="form-group" id="id42"> <input type="text" value="Results" name="s12" maxlength="255" id="5"> <div class="form-group" id="id43"> <input type="text" value="Results" name="s12" maxlength="255" id="id224"> </div> </div> </div> </div> </div> My Qjuery script var row = $(".item:first").clone(false).get(0); $(row).children().each(function () { updateElementIndex(this, prefix, formCount); if ($(this).attr('type') == 'text') { $(this).val(''); } if ($(this).attr('type') == 'hidden' && ($(this).attr('name') != 'csrfmiddlewaretoken')) { $(this).val(''); } if ($(this).attr('type') == 'file') { $(this).val(''); } if ($(this).attr('type') == 'checkbox') { $(this).attr('checked', false); } $(this).remove('a'); }); // Relabel or rename all the relevant bits $(row).children().children().each(function () { updateElementIndex(this, prefix, formCount) if ($(this).attr('type') == 'text') { $(this).val(''); } if ($(this).attr('type') == 'hidden' && ($(this).attr('name') != 'csrfmiddlewaretoken')) { $(this).val(''); } if ($(this).attr('type') == 'file') { $(this).val(''); } if ($(this).attr('type') == 'checkbox') { $(this).attr('checked', false); } $(this).remove('a'); });

  • Is it possible to convert this asp to asp.net?

    - by Phil
    I have been tasked with sifting through the worst classic asp spaghetti i've ever come across. The script runs a series of recordsets in sequence, getting 1 record at a time. As the record is built it takes the id and passes it to the next loop, which gets data, and passes on the id to the next loop. It then continues in this manner and builds an unordered list, kicking out the required html as it goes. Here are my efforts so far: have a class delivering data via sqldatareaders and output these to nested repeaters (this failed due to not being able to loop and get the id) Have a datatable populated with all the required data, then datatable.select to filter it out. have 4 datareaders looping and building the ul arraylists (I couldnt get the id's to match up) Please can you suggest the best method (with a bit of sample code if possible) to go about doing this conversion? Here is the code (sorry its long / horrible / spaghetti!!!) <% set RSMenuLevel0 = conn.execute("select id, DepartmentID, GroupingID, Heading, OrderID, Publish, moduleid, url, urltarget " &_ "from Grouping where (DepartmentID = 0 and GroupingID = 0 and Publish <> 0) order by OrderID") %> <% if session("JavaScriptEnabled") = "False" Then %> <% while not RSMenuLevel0.EOF if RSMenuLevel0("Publish") <> 0 then Menu0heading = RSMenuLevel0("Heading") Menu0id = RSMenuLevel0("id") %> <%if RSMenuLevel0("url") > "" and RSMenuLevel0("moduleid") = 0 then%> &nbsp;<a href="http://<%=RSMenuLevel0("url")%>" target="<%=RSMenuLevel0("urltarget")%>"><%=Menu0heading%></a> <%else%> &nbsp;<a href="/default.asp?id=<%=Menu0id%>"><%=Menu0heading%></a> <%end if%> <% end if RSMenuLevel0.MoveNext wend %> <% else %> <ul id="Menu1" class="MM"> <%if home <> 1 then%> <!-- <li><a href="/default.asp"><span class="item">Home</span></a> --> <%end if%> <% numone=0 while not RSMenuLevel0.EOF ' numone = numone + 1 Menu0heading = RSMenuLevel0("Heading") 'itemID = lcase(replace(Menu0heading," ","")) Menu0id = RSMenuLevel0("id") if RSMenuLevel0("url") > "" and RSMenuLevel0("moduleid") = 0 then url = RSMenuLevel0("url") if instr(url,"file:///") > 0 then %> <li><a href="<%=RSMenuLevel0("url")%>" target="<%=RSMenuLevel0("urltarget")%>" <%if numone=1 then%>class="CURRENT"<%end if%>><span class="item"><%=Menu0heading%></span></a> <%else%> <li><a href="http://<%=RSMenuLevel0("url")%>" target="<%=RSMenuLevel0("urltarget")%>" <%if numone=1 then%>class="CURRENT"<%end if%>><span class="item"><%=Menu0heading%></span></a> <%end if%> <%else%> <li><a href="/default.asp?id=<%=RSMenuLevel0("id")%>" <%if numone=1 then%>class="CURRENT"<%end if%>><span class="item"><%=Menu0heading%></span></a> <%end if%> <% set RSMenuLevel1 = conn.execute("select id, DepartmentID, GroupingID, Heading, OrderID, Publish, moduleid, url, urltarget " &_ "from Grouping where (DepartmentID = 0 and GroupingID = " & Menu0id & " and Publish <> 0) order by OrderID") if not RSMenuLevel1.EOF then %> <ul> <% while not RSMenuLevel1.EOF Menu1heading = RSMenuLevel1("Heading") Menu1id = RSMenuLevel1("id") if RSMenuLevel1("url") > "" and RSMenuLevel1("moduleid") = 0 then url = RSMenuLevel1("url") if instr(url,"file:///") > 0 then %> <li><a href="<%=RSMenuLevel1("url")%>" target="<%=RSMenuLevel1("urltarget")%>"><%=Menu1heading%></a> <%else%> <li><a href="http://<%=RSMenuLevel1("url")%>" target="<%=RSMenuLevel1("urltarget")%>"><%=Menu1heading%></a> <%end if%> <%else%> <li><a href="/default.asp?id=<%=RSMenuLevel1("id")%>"><%=Menu1heading%></a> <%end if%> <% set RSMenuLevel2 = conn.execute("select id, DepartmentID, GroupingID, Heading, OrderID, Publish, moduleid, url, urltarget " &_ "from Grouping where (DepartmentID = 0 and GroupingID = " & Menu1id & " and Publish <> 0) order by OrderID") if not RSMenuLevel2.EOF then %> <ul> <% while not RSMenuLevel2.EOF Menu2heading = RSMenuLevel2("Heading") Menu2id = RSMenuLevel2("id") if RSMenuLevel2("url") > "" and RSMenuLevel2("moduleid") = 0 then %> <li><a href="http://<%=RSMenuLevel2("url")%>" target="<%=RSMenuLevel2("urltarget")%>"><%=Menu2heading%></a> <%else%> <li><a href="/default.asp?id=<%=RSMenuLevel2("id")%>"><%=Menu2heading%></a> <%end if%> <% set RSMenuLevel3 = conn.execute("select id, DepartmentID, GroupingID, Heading, OrderID, Publish, moduleid, url, urltarget " &_ "from Grouping where (DepartmentID = 0 and GroupingID = " & Menu2id & " and Publish <> 0) order by OrderID") if not RSMenuLevel3.EOF then %> <ul> <% while not RSMenuLevel3.EOF Menu3heading = RSMenuLevel3("Heading") Menu3id = RSMenuLevel3("id") if RSMenuLevel3("url") > "" and RSMenuLevel3("moduleid") = 0 then %> <li><a href="http://<%=RSMenuLevel3("url")%>" target="<%=RSMenuLevel3("urltarget")%>"><%=Menu3heading%></a></li> <%else%> <li><a href="/default.asp?id=<%=RSMenuLevel3("id")%>"><%=Menu3heading%></a></li> <%end if%> <% RSMenuLevel3.MoveNext wend %> </ul> <% end if RSMenuLevel2.MoveNext %> </li> <% wend %> </ul> <% end if RSMenuLevel1.MoveNext %> </li> <% wend %> </ul> <% end if RSMenuLevel0.MoveNext %> </li> <% wend %> </ul> <% end if %>

  • How to break out from nested doseqs

    - by fizbin
    Hi, I have a question regarding nested doseq loops. In the start function, once I find an answer I set the atom to true, so that the outer loop validation with :while fails. However it seems that it doesn't break it, and the loops keep on going. What's wrong with it? I am also quite confused with the usage of atoms, refs, agents (Why do they have different names for the update functions when then the mechanism is almost the same?) etc. Is it okay to use an atom in this situation as a flag? Obviously I need a a variable like object to store a state. (def pentagonal-list (map (fn [a] (/ (* a (dec (* 3 a))) 2)) (iterate inc 1))) (def found (atom false)) (defn pentagonal? [a] (let [y (/ (inc (Math/sqrt (inc (* 24 a)))) 6) x (mod (* 10 y) 10)] (if (zero? x) true false))) (defn both-pent? [a b] (let [sum (+ b a) diff (- a b)] (if (and (pentagonal? sum) (pentagonal? diff)) true false))) (defn start [] (doseq [x pentagonal-list :while (false? @found)] (doseq [y pentagonal-list :while (<= y x)] (if (both-pent? x y) (do (reset! found true) (println (- x y)))))))

  • Problem using form builder & DOM manipulation in Rails with multiple levels of nested partials

    - by Chris Hart
    I'm having a problem using nested partials with dynamic form builder code (from the "complex form example" code on github) in Rails. I have my top level view "new" (where I attempt to generate the template): <% form_for (@transaction_group) do |txngroup_form| %> <%= txngroup_form.error_messages %> <% content_for :jstemplates do -%> <%= "var transaction='#{generate_template(txngroup_form, :transactions)}'" %> <% end -%> <%= render :partial => 'transaction_group', :locals => { :f => txngroup_form, :txn_group => @transaction_group }%> <% end -%> This renders the transaction_group partial: <div class="content"> <% logger.debug "in partial, class name = " + txn_group.class.name %> <% f.fields_for txn_group.transactions do |txn_form| %> <table id="transactions" class="form"> <tr class="header"><td>Price</td><td>Quantity</td></tr> <%= render :partial => 'transaction', :locals => { :tf => txn_form } %> </table> <% end %> <div>&nbsp;</div><div id="container"> <%= link_to 'Add a transaction', '#transaction', :class => "add_nested_item", :rel => "transactions" %> </div> <div>&nbsp;</div> ... which in turn renders the transaction partial: <tr><td><%= tf.text_field :price, :size => 5 %></td> <td><%= tf.text_field :quantity, :size => 2 %></td></tr> The generate_template code looks like this: def generate_html(form_builder, method, options = {}) options[:object] ||= form_builder.object.class.reflect_on_association(method).klass.new options[:partial] ||= method.to_s.singularize options[:form_builder_local] ||= :f form_builder.fields_for(method, options[:object], :child_index => 'NEW_RECORD') do |f| render(:partial => options[:partial], :locals => { options[:form_builder_local] => f }) end end def generate_template(form_builder, method, options = {}) escape_javascript generate_html(form_builder, method, options) end (Obviously my code is not the most elegant - I was trying to get this nested partial thing worked out first.) My problem is that I get an undefined variable exception from the transaction partial when loading the view: /Users/chris/dev/ss/app/views/transaction_groups/_transaction.html.erb:2:in _run_erb_app47views47transaction_groups47_transaction46html46erb_locals_f_object_transaction' /Users/chris/dev/ss/app/helpers/customers_helper.rb:29:in generate_html' /Users/chris/dev/ss/app/helpers/customers_helper.rb:28:in generate_html' /Users/chris/dev/ss/app/helpers/customers_helper.rb:34:in generate_template' /Users/chris/dev/ss/app/views/transaction_groups/new.html.erb:4:in _run_erb_app47views47transaction_groups47new46html46erb' /Users/chris/dev/ss/app/views/transaction_groups/new.html.erb:3:in _run_erb_app47views47transaction_groups47new46html46erb' /Users/chris/dev/ss/app/views/transaction_groups/new.html.erb:1:in _run_erb_app47views47transaction_groups47new46html46erb' /Users/chris/dev/ss/app/controllers/transaction_groups_controller.rb:17:in new' I'm pretty sure this is because the do loop for form_for hasn't executed yet (?)... I'm not sure that my approach to this problem is the best, but I haven't been able to find a better solution for dynamically adding form partials to the DOM. Basically I need a way to add records to a has_many model dynamically on a nested form. Any recommendations on a way to fix this particular problem or (even better!) a cleaner solution are appreciated. Thanks in advance. Chris

  • Datapager in silverlight 4 -Nested datagrid visibility issue

    - by Archie
    I have a datagrid in silverlight with child datagrid nested in it. Also I have a DataPager on the outer datagrid. The code looks like this: <data:DataGrid x:Name="dgData" Width="600" ItemsSource="{Binding}" AutoGenerateColumns="False" IsReadOnly="True" HorizontalScrollBarVisibility="Hidden" CanUserSortColumns="False" RowDetailsVisibilityChanged="dgData_RowDetailsVisibilityChanged" Margin="20,0" Grid.RowSpan="2"> <data:DataGrid.Columns> <data:DataGridTextColumn Header="Item" Width="*" Binding="{Binding ItemName,Mode=TwoWay}"/> <data:DataGridTextColumn Header="Company" Width="*" Binding="{Binding Company,Mode=TwoWay}"/> </data:DataGrid.Columns> <data:DataGrid.RowDetailsTemplate> <DataTemplate> <data:DataGrid x:Name="dgRowDetail" Width="400" HorizontalScrollBarVisibility="Hidden" AutoGenerateColumns="False" Visibility="Collapsed"> <data:DataGrid.Columns> <data:DataGridTextColumn Header="Date" Width="*" Binding="{Binding Date,Mode=TwoWay}"/> <data:DataGridTextColumn Header="Price" Width="*" Binding="{Binding Price,Mode=TwoWay}"/> </data:DataGrid.Columns> </data:DataGrid> </DataTemplate> </data:DataGrid.RowDetailsTemplate> </data:DataGrid> <data:DataPager x:Name="dpData" HorizontalAlignment="Center" DisplayMode="FirstLastPreviousNextNumeric" Source="{Binding}"/> I have one PagedCollectionView pgv which is bound to outer datagrid as: DataContext = pgv; When the row is clicked I set the child datagrid's ItemsSource property to another PagedCollectionView. My problem is it works fine except for the first row for the first time. When I click on it, it doesn't fire the dgData_RowDetailsVisibilityChanged event. Also, when I click on second row, firstly first row fires the event and then the second row fires it and shows the nested grid. Please help.

  • C# using namespace directive in nested namespaces

    - by MoSlo
    Right, I've usually used 'using' directives as follows using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace AwesomeLib { //awesome award winning class declarations making use of Linq } i've recently seen examples of such as using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace AwesomeLib { //awesome award winning class declarations making use of Linq namespace DataLibrary { using System.Data; //Data access layers and whatnot } } Granted, i understand that i can put USING inside of my namespace declaration. Such a thing makes sense to me if your namespaces are in the same root (they organized). System; namespace 1 {} namespace 2 { System.data; } But what of nested namespaces? Personally, I would leave all USING declarations at the top where you can find them easily. Instead, it looks like they're being spread all over the source file. Is there benefit to the USING directives being used this way in nested namespaces? Such as memory management or the JIT compiler?

  • Nested Linear layout only shows first view after being set from gone to visible in Android

    - by Adam
    Hi guys, I am developing an Android app but I'm still pretty new. I want to have a button, and when you push that button, a few TextViews and Buttons will appear. So I have a main linear layout, and then another linear layout nested inside containing the things I want hidden. I have the nested linear layout set to android:visibility="gone". The problem I am having is that it only shows the first item inside the hidden linear layout instead of all of them. The way I try to make it appear is vgAddView = (ViewGroup)findViewById(R.id.add_details); btnAche.setOnClickListener(new OnClickListener(){ public void onClick(View v){ vgAddView.setVisibility(0); } }); My XML file is this <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <Button android:text="@string/but_stomach_ache" android:id="@+id/but_stomach_ache" android:layout_width="fill_parent" android:layout_height="wrap_content"> </Button> <Button android:text="@string/but_food" android:id="@+id/but_food" android:layout_width="fill_parent" android:layout_height="wrap_content"> </Button> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:id="@+id/add_details" android:visibility="gone"> <TextView android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="@string/when_happen"> </TextView> <Button android:text="@string/happen_now" android:id="@+id/happen_now" android:layout_width="fill_parent" android:layout_height="wrap_content"> </Button> </LinearLayout> </LinearLayout>

  • For "draggable" div tags that are NOT nested: JQuery/JavaScript div tag “containment” approach/algor

    - by Pete Alvin
    Background: I've created an online circuit design application where .draggable() div tags are containers that contain smaller div containers and so forth. Question: For any particular div tag I need to quickly identify if it contains other div tags (that may in turn contain other div tags). -- Since the div tags are draggable, in the DOM they are NOT nested inside each other but I think are absolutely positioned. So I think that a "hit testing" approach is the only way to determine containment, unless there is some "secret" routine built-in somewhere that could help with this. I've searched JQuery and I don't see any built-in routine for this. Does anyone know of an algorithm that's quicker than O(n^2)? Seems like I have to walk the list of div tags in an outer loop (n) and have an inner loop (another n) to compare against all other div tags and do a "containment test" (position, width, height), building a list of contained div tags. That's n-squared. Then I have to build a list of all nested div tags by concatenating contained lists. So the total would be O(n^2)+n. There must be a better way?

  • Nested URLs and Rewrite rules in Apache2

    - by Radha Krishna. S.
    Hi, I need some help with rewrite rules and nested URLs. I am using TikiWiki for my website and am in the process of setting up SE friendly URLs for my projects. Specifically, I have the following rewrite rule for www.example.com/projects to point to a page that lists out all the projects hosted in example. RewriteRule ^Projects$ articles?type=Project [L] This works fine. Now, I would like to point www.example.com/projects/project1 to point to a specific project. I have this rewrite rule RewriteRule ^(Projects/Project1)$ tiki-read_article.php?articleId=6 This works, but partially. The content is all rendered as text but the theme - images/ css etc all go for a toss - the page is completely in text. I understand that this happens 'cause the relative paths in the theme/ css/ images all refer to Projects as the base folder instead of the root of the website. I don't want to touch the CMS portion - change the theme/ css/ image paths in the files, more for reasons of upgradability. Can someone help me understand and write a rule so that the above nested URL works? Regards, Radha

  • Subsonic 3 ActiveRecord nested select for NotIn bug?

    - by Junto
    I have the following Subsonic 3.0 query, which contains a nested NotIn query: public List<Order> GetRandomOrdersForNoReason(int shopId, int typeId) { // build query var q = new SubSonic.Query.Select().Top("1") .From("Order") .Where("ShopId") .IsEqualTo(shopId) .And(OrderTable.CustomerId).NotIn( new Subsonic.Query.Select("CustomerId") .From("Customer") .Where("TypeId") .IsNotEqualTo(typeId)) .OrderDesc("NewId()"); // Output query Debug.WriteLine(q.ToString()); // returned typed list return q.ExecuteTypedList<Order>(); } The internal query appears to be incorrect: SELECT TOP 1 * FROM [Order] WHERE ShopId = @0 AND CustomerId NOT IN (SELECT CustomerId FROM [Customer] WHERE TypeId = @0) ORDER BY NewId() ASC You'll notice that both parameters are @0. I'm assuming that the parameters are enumerated (starting at zero), for each "new" Select query. However, in this case where the two Select queries are nested, I would have expected the output to have two parameters named @0 and @1. My query is based on one that Rob Conery gave on his blog as a preview of the "Pakala" query tool that became Subsonic 3. His example was: int records = new Select(Northwind.Product.Schema) .Where("productid") .In( new Select("productid").From(Northwind.Product.Schema) .Where("categoryid").IsEqualTo(5) ) .GetRecordCount(); Has anyone else seen this behavior? Is it a bug, or is this an error or my part? Since I'm new to Subsonic I'm guessing that this probably programmer error on my part but I'd like confirmation if possible.

    Assume a nested hash structure %old_hash .. my %old_hash; $old_hash{"foo"}{"bar"}{"zonk"} = "hello"; .. which we want to "flatten" (sorry if that's the wrong terminology!) to a non-nested hash using the sub &flatten(...) so that .. my %h = &flatten(\%old_hash); die unless($h{"zonk"} eq "hello"); The following definition of &flatten(...) does the trick: sub flatten { my $hashref = shift; my %hash; my %i = %{$hashref}; foreach my $ii (keys(%i)) { my %j = %{$i{$ii}}; foreach my $jj (keys(%j)) { my %k = %{$j{$jj}}; foreach my $kk (keys(%k)) { my $value = $k{$kk}; $hash{$kk} = $value; } } } return %hash; } While the code given works it is not very readable or clean. My question is two-fold: In what ways does the given code not correspond to modern Perl best practices? Be harsh! :-) How would you clean it up?

  • Same route nested in multiple resources ember.js

    - by Daniel Upton
    I'm building an ember.js app which has a model called "Programme". A user can drill down to a programme by going: Genre > Subgenre > Programme or Folder > List > Programme Here's my router: this.resource('mylists', { path: '/' }, function() { this.resource('folder', { path: '/folder/:folder_id' }, function() { this.resource('list', { path: '/list/:list_id' }, function() { this.resource('programme', { path: '/programme/:programme_id' }); }); }); }); this.resource('catalogue', function() { this.resource('genre', { path: '/genre/:genre_id' }, function() { this.resource('subgenre', { path: '/subgenre/:subgenre_id' }, function() { this.resource('programme', { path: '/programme/:programme_id' }); }); }); }); The UI needs to be deeply nested (the genre view renders in the outlet of the catalogue template, the subgenre in the outlet of the genre template... and so forth). The problem I have is as both generated routes are called ProgrammeRoute when I linkTo the programme route inside the list template, it actually goes to the programme route nested in the subgenre route. What should I be doing here? To work around it I've named one route ListProgrammeRoute and SubgenreProgrammeRoute but that leads to some duplication.

  • binding nested json object value to a form field

    - by Jack
    I am building a dynamic form to edit data in a json object. First, if something like this exists let me know. I would rather not build it but I have searched many times for a tool and have found only tree like structures that require entering quotes. I would be happy to treat all values as strings. This edit functionality is for end users so it needs to be easy an not intimidating. So far I have code that generates nested tables to represent a json object. For each value I display a form field. I would like to bind the form field to the associated nested json value. If I could store a reference to the json value I would build an array of references to each value in a json object tree. I have not found a way to do that with javascript. My last resort approach will be to traverse the table after edits are made. I would rather have dynamic updates but a single submit would be better than nothing. Any ideas? // the json in files nests only a few levels. Here is the format of a simple case, { "researcherid_id":{ "id_key":"researcherid_id", "description":"Use to retrieve bibliometric data", "url_template" :[ { "name": "Author Detail", "url": "http://www.researcherid.com/rid/${key}" } ] } } $.get('file.json',make_json_form); function make_json_form(response) { dataset = $.secureEvalJSON(response); // iterate through the object and generate form field for string values. } // Then after the form is edited I want to display the raw updated json (then I want to save it but that is for another thread) // now I iterate through the form and construct the json object // I would rather have the dataset object var updated on focus out after each edit. function show_json(form_id){ var r = {}; var el = document.getElementById(form_id); table_to_json(r,el,null); $('body').html(formattedJSON(r)); }

  • Hierarchical/Nested Database Structure for Comments

    - by Stephen Melrose
    Hi, I'm trying to figure out the best approach for a database schema for comments. The problem I'm having is that the comments system will need to allow nested/hierarchical comments, and I'm not sure how to design this out properly. My requirements are, Comments can be made on comments, so I need to store the tree hierarchy I need to be able to query the comments in the tree hierarchy order, but efficiently, preferably in a fast single query, but I don't know if this is possible I'd need to make some wierd queries, e.g. pull out the latest 5 root comments, and a maximum of 3 children for each one of those I read an article on the MySQL website on this very subject, http://dev.mysql.com/tech-resources/articles/hierarchical-data.html The "Nested Set Model" in theory sounds like it will do what I need, except I'm worried about querying the thing, and also inserting. If this is the right approach, How would I do my 3rd requirement above? If I have 2000 comments, and I add a new sub-comment on the first comment, that will be a LOT of updating to do. This doesn't seem right to me? Or is there a better approach for the type of data I'm wanting to store and query? Thank you
