  1. POAccessing Django Model Methods Through TastyPie
    text
    copied!<p>I am trying to access a purchase method that I have written inside my item model through a TastyPie API. Here is the method:</p> <pre><code>def purchase(self, buyer): sold = False seller = self.seller if self.for_sale != False: if seller != buyer: self.for_sale = False sold = True return sold </code></pre> <p>I have confirmed that this function works in the shell. Here is the purchase function I have written in the resource to call my model method:</p> <pre><code>def prepend_urls(self): return [ url(r'^(?P&lt;resource_name&gt;%s)/(?P&lt;pk&gt;\w[\w/-]*)/purchase%s$' % (self._meta.resource_name, trailing_slash()), self.wrap_view('purchase'), name = 'api_item_purchase'), ] def purchase(self, request, **kwargs): self.method_check(request, allowed = ['post']) data = self.deserialize(request, request.body, format = request.META.get('CONTENT_TYPE', 'application/json')) item_id = data.get('item_id', '') print item_id buyer = request.user print buyer item = Item.objects.get(pk = item_id) print item return self.create_response(request, item.purchase(buyer)) </code></pre> <p>I'm basing this off of another stack that I found:</p> <p><a href="https://stackoverflow.com/questions/14085865/exposing-model-method-with-tastypie">Exposing model method with Tastypie</a></p> <p>but it doesn't seem to be working, I get 200 server ok in addition to "JSON text did not start with array or object and option to allow fragments not set" but the method never actually gets called.</p>
