Given two related Django models A and B in a OneToMany relationship: models.py class A(models.Model): name = models.CharField(max_length=5) class B(models.Model): name = models.CharField(max_length=5) a = models.ForeignKey(A) And given (potentially non-optimal) Tastypie resources: api.py class AResource(ModelResource): bs = fields.ToManyField( 'projectname.api.BResource', 'bs', full = True) class Meta: queryset = A.objects.all() class BResource(ModelResource): a = fields.ToOneField( AResource, 'a', full = True) class Meta: queryset = B.objects.all() Let's assume the database is empty so far.

I have two associated tables. Venues and Specials . A venue can have many specials . Once a user has created a venue I wish to allow them to create a special on the venues#index page. By using nested resources I have achieved the desired URL: /venues/5/specials/new . However, my current code results with: No route matches {:controller=>"specials", :format=>nil} I'm guessing the error is with my SpecialsController and the def new and def create functions. I would like the URL to take me to a form page where I can enter new data for the specials <%= link_to 'Add Special', new_venue_special_path

I'm working out an algorithm to get permutations like 123 132 213 231 312 321 I'm doing it using nested foreach loops. for (..) { for(..) { for(..) { echo $i . $j . $k . "<br />"; } } } Problem is those # of nested loops are optimized for 3-spot permutations. How can I could I dynamically set the number of nested for loops to generate 4-letter or 5-letter permutations? Recursive method is the way to go. But you can also use eval function like: $loop = iteration('i',10) . iteration('j',10). iteration('k',10). iteration('l',10); $loop .= "print \"\$i \$j \$k \$l\\n\";"; // $loop now has: for($i

I have inherited a project recently that uses UI-Router to route between states in a management portal site. There are certain complexities to this portal that require our states to primarily be siblings, rather than related parent/child. This has created an issue getting breadcrumbs to work using ncyBreadcrumb. Before I ditch ncy and develop something of my own, I am wondering if there is a way to resolve my issues. The classic ui-router example is the contact list. You may have an index state, underneath which you have contacts.list and contacts.details . Both of the contacts states are

I've loaded my iTunes song data into a MySQL database and I'm trying to use PHP to get a JSON feed of album information. This code.. <?php /* Connect to database */ require ('include/connect.php'); /* Build the query */ $query = "SELECT a.album,a.name,a.artist,a.year AS track_year, b.year AS album_year FROM staging a, (SELECT album, MAX(year) AS year FROM staging GROUP BY album) b WHERE a.album = b.album"; /* Loop through the results and build a JSON array for the data table */ $result = $mysqli->query($query); $info = array(); while ($row = $result->fetch_array(MYSQLI_ASSOC)) { if (!isset(

I'd like to group some of my Vue.js methods together in a sort of "submethod" class, but I only seem to be able to have single level methods. For example, if I wanted to have a set of methods dealing purely with button actions: new Vue({ el: '#app', data: { }, methods: { buttonHandlers: { handler1: function() { dosomething; }, handler2: function() { dosomething; } } } }); I would expect to be able to then use something like: <button v-on:click="buttonHandlers.handler1">Click Me</button> but nothing happens. I have tried forcing the function to run by adding brackets: <button v-on:click=
